-5.3.2 Handling MSI-X allocation
-
-Determining the number of MSI-X vectors allocated to a function is
-dependent on the number of MSI capable devices and MSI-X capable
-devices populated in the system. The policy of allocating MSI-X
-vectors to a function is defined as the following:
-
-#of MSI-X vectors allocated to a function = (x - y)/z where
-
-x = 	The number of available PCI vector resources by the time
-	the device driver calls pci_enable_msix(). The PCI vector
-	resources is the sum of the number of unassigned vectors
-	(new) and the number of released vectors when any MSI/MSI-X
-	device driver switches its hardware device back to a legacy
-	mode or is hot-removed.	The number of unassigned vectors
-	may exclude some vectors reserved, as defined in parameter
-	NR_HP_RESERVED_VECTORS, for the case where the system is
-	capable of supporting hot-add/hot-remove operations. Users
-	may change the value defined in NR_HR_RESERVED_VECTORS to
-	meet their specific needs.
-
-y =	The number of MSI capable devices populated in the system.
-	This policy ensures that each MSI capable device has its
-	vector reserved to avoid the case where some MSI-X capable
-	drivers may attempt to claim all available vector resources.
-
-z =	The number of MSI-X capable devices populated in the system.
-	This policy ensures that maximum (x - y) is distributed
-	evenly among MSI-X capable devices.
-
-Note that the PCI subsystem scans y and z during a bus enumeration.
-When the PCI subsystem completes configuring MSI/MSI-X capability
-structure of a device as requested by its device driver, y/z is
-decremented accordingly.
-
-5.3.3 Handling MSI-X shortages
-
-For the case where fewer MSI-X vectors are allocated to a function
-than requested, the function pci_enable_msix() will return the
-maximum number of MSI-X vectors available to the caller. A device
-driver may re-send its request with fewer or equal vectors indicated
-in the return. For example, if a device driver requests 5 vectors, but
-the number of available vectors is 3 vectors, a value of 3 will be
-returned as a result of pci_enable_msix() call. A function could be
-designed for its driver to use only 3 MSI-X table entries as
-different combinations as ABC--, A-B-C, A--CB, etc. Note that this
-patch does not support multiple entries with the same vector. Such
-attempt by a device driver to use 5 MSI-X table entries with 3 vectors
-as ABBCC, AABCC, BCCBA, etc will result as a failure by the function
-pci_enable_msix(). Below are the reasons why supporting multiple
-entries with the same vector is an undesirable solution.
-
-	- The PCI subsystem cannot determine the entry that
-	  generated the message to mask/unmask MSI while handling
-	  software driver ISR. Attempting to walk through all MSI-X
-	  table entries (2048 max) to mask/unmask any match vector
-	  is an undesirable solution.
-
-	- Walking through all MSI-X table entries (2048 max) to handle

-NAPI is a proven (www.cyberus.ca/~hadi/usenix-paper.tgz) technique
-to improve network performance on Linux. For more details please
-read that paper.
-NAPI provides a "inherent mitigation" which is bound by system capacity
-as can be seen from the following data collected by Robert on Gigabit

-packets out of the rx ring. Note from this that the lower the
-load the more we could clean up the rxring
-"Ndone" == is the converse of "Done". Note again, that the higher
-the load the more times we couldn't clean up the rxring.
-
-Observe that:
-when the NIC receives 890Kpackets/sec only 17 rx interrupts are generated. 
-The system cant handle the processing at 1 interrupt/packet at that load level. 
-At lower rates on the other hand, rx interrupts go up and therefore the
-interrupt/packet ratio goes up (as observable from that table). So there is
-possibility that under low enough input, you get one poll call for each
-input packet caused by a single interrupt each time. And if the system 
-cant handle interrupt per packet ratio of 1, then it will just have to 
-chug along ....
-
-
-0) Prerequisites:
-==================
-A driver MAY continue using the old 2.4 technique for interfacing
-to the network stack and not benefit from the NAPI changes.
-NAPI additions to the kernel do not break backward compatibility.
-NAPI, however, requires the following features to be available:
-
-A) DMA ring or enough RAM to store packets in software devices.
-
-B) Ability to turn off interrupts or maybe events that send packets up 
-the stack.
-
-NAPI processes packet events in what is known as dev->poll() method.
-Typically, only packet receive events are processed in dev->poll(). 
-The rest of the events MAY be processed by the regular interrupt handler 
-to reduce processing latency (justified also because there are not that 
-many of them).
-Note, however, NAPI does not enforce that dev->poll() only processes 
-receive events. 
-Tests with the tulip driver indicated slightly increased latency if
-all of the interrupt handler is moved to dev->poll(). Also MII handling
-gets a little trickier.
-The example used in this document is to move the receive processing only
-to dev->poll(); this is shown with the patch for the tulip driver.
-For an example of code that moves all the interrupt driver to 
-dev->poll() look at the ported e1000 code.
-
-There are caveats that might force you to go with moving everything to 
-dev->poll(). Different NICs work differently depending on their status/event 
-acknowledgement setup. 
-There are two types of event register ACK mechanisms.
-	I)  what is known as Clear-on-read (COR).
-	when you read the status/event register, it clears everything!
-	The natsemi and sunbmac NICs are known to do this.
-	In this case your only choice is to move all to dev->poll()
-
-	II) Clear-on-write (COW)
-	 i) you clear the status by writing a 1 in the bit-location you want.
-		These are the majority of the NICs and work the best with NAPI.
-		Put only receive events in dev->poll(); leave the rest in
-		the old interrupt handler.
-	 ii) whatever you write in the status register clears every thing ;->
-		Cant seem to find any supported by Linux which do this. If
-		someone knows such a chip email us please.
-		Move all to dev->poll()
-
-C) Ability to detect new work correctly.
-NAPI works by shutting down event interrupts when there's work and
-turning them on when there's none. 
-New packets might show up in the small window while interrupts were being 
-re-enabled (refer to appendix 2).  A packet might sneak in during the period 
-we are enabling interrupts. We only get to know about such a packet when the 
-next new packet arrives and generates an interrupt. 
-Essentially, there is a small window of opportunity for a race condition
-which for clarity we'll refer to as the "rotting packet".
-
-This is a very important topic and appendix 2 is dedicated for more 
-discussion.
-
-Locking rules and environmental guarantees
-==========================================
-
--Guarantee: Only one CPU at any time can call dev->poll(); this is because
-only one CPU can pick the initial interrupt and hence the initial
-netif_rx_schedule(dev);
-- The core layer invokes devices to send packets in a round robin format.
-This implies receive is totally lockless because of the guarantee that only 
-one CPU is executing it.
--  contention can only be the result of some other CPU accessing the rx
-ring. This happens only in close() and suspend() (when these methods
-try to clean the rx ring); 
-****guarantee: driver authors need not worry about this; synchronization 
-is taken care for them by the top net layer.
--local interrupts are enabled (if you dont move all to dev->poll()). For 
-example link/MII and txcomplete continue functioning just same old way. 
-This improves the latency of processing these events. It is also assumed that 
-the receive interrupt is the largest cause of noise. Note this might not 
-always be true. 
-[according to Manfred Spraul, the winbond insists on sending one 
-txmitcomplete interrupt for each packet (although this can be mitigated)].
-For these broken drivers, move all to dev->poll().
-
-For the rest of this text, we'll assume that dev->poll() only
-processes receive events.
-
-new methods introduce by NAPI
-=============================
-
-a) netif_rx_schedule(dev)
-Called by an IRQ handler to schedule a poll for device
-
-b) netif_rx_schedule_prep(dev)
-puts the device in a state which allows for it to be added to the
-CPU polling list if it is up and running. You can look at this as
-the first half of  netif_rx_schedule(dev) above; the second half
-being c) below.
-
-c) __netif_rx_schedule(dev)
-Add device to the poll list for this CPU; assuming that _prep above
-has already been called and returned 1.
-
-d) netif_rx_reschedule(dev, undo)
-Called to reschedule polling for device specifically for some
-deficient hardware. Read Appendix 2 for more details.
-
-e) netif_rx_complete(dev)
-
-Remove interface from the CPU poll list: it must be in the poll list
-on current cpu. This primitive is called by dev->poll(), when
-it completes its work. The device cannot be out of poll list at this
-call, if it is then clearly it is a BUG(). You'll know ;->
-
-All of the above methods are used below, so keep reading for clarity.
-
-Device driver changes to be made when porting NAPI
-==================================================
-
-Below we describe what kind of changes are required for NAPI to work.
-
-1) introduction of dev->poll() method 
-=====================================
-
-This is the method that is invoked by the network core when it requests
-for new packets from the driver. A driver is allowed to send upto
-dev->quota packets by the current CPU before yielding to the network
-subsystem (so other devices can also get opportunity to send to the stack).
-
-dev->poll() prototype looks as follows:
-int my_poll(struct net_device *dev, int *budget)
-
-budget is the remaining number of packets the network subsystem on the
-current CPU can send up the stack before yielding to other system tasks.
-*Each driver is responsible for decrementing budget by the total number of
-packets sent.
-	Total number of packets cannot exceed dev->quota.
-
-dev->poll() method is invoked by the top layer, the driver just sends if it 
-can to the stack the packet quantity requested.
-
-more on dev->poll() below after the interrupt changes are explained.
-
-2) registering dev->poll() method
-===================================
-
-dev->poll should be set in the dev->probe() method. 
-e.g:
-dev->open = my_open;
-.
-.
-/* two new additions */
-/* first register my poll method */
-dev->poll = my_poll;
-/* next register my weight/quanta; can be overridden in /proc */
-dev->weight = 16;
-.
-.
-dev->stop = my_close;
-
-
-
-3) scheduling dev->poll()
-=============================
-This involves modifying the interrupt handler and the code
-path which takes the packet off the NIC and sends them to the 
-stack.
-
-it's important at this point to introduce the classical D Becker 
-interrupt processor:
-
-------------------
-static irqreturn_t
-netdevice_interrupt(int irq, void *dev_id, struct pt_regs *regs)
-{
-
-	struct net_device *dev = (struct net_device *)dev_instance;
-	struct my_private *tp = (struct my_private *)dev->priv;
-
-	int work_count = my_work_count;
-        status = read_interrupt_status_reg();
-        if (status == 0)
-                return IRQ_NONE; /* Shared IRQ: not us */
-        if (status == 0xffff)
-                return IRQ_HANDLED;      /* Hot unplug */
-        if (status & error)
-		do_some_error_handling()
-        
-	do {
-		acknowledge_ints_ASAP();
-
-		if (status & link_interrupt) {
-			spin_lock(&tp->link_lock);
-			do_some_link_stat_stuff();
-			spin_lock(&tp->link_lock);
-		}
-		
-		if (status & rx_interrupt) {
-			receive_packets(dev);
-		}
-
-		if (status & rx_nobufs) {
-			make_rx_buffs_avail();
-		}
-			
-		if (status & tx_related) {
-			spin_lock(&tp->lock);
-			tx_ring_free(dev);
-			if (tx_died)
-				restart_tx();
-			spin_unlock(&tp->lock);
-		}
-
-		status = read_interrupt_status_reg();
-
-	} while (!(status & error) || more_work_to_be_done);
-	return IRQ_HANDLED;
-}
-
-----------------------------------------------------------------------
-
-We now change this to what is shown below to NAPI-enable it:
-
-----------------------------------------------------------------------
-static irqreturn_t
-netdevice_interrupt(int irq, void *dev_id, struct pt_regs *regs)
-{
-	struct net_device *dev = (struct net_device *)dev_instance;
-	struct my_private *tp = (struct my_private *)dev->priv;
-
-        status = read_interrupt_status_reg();
-        if (status == 0)
-                return IRQ_NONE;         /* Shared IRQ: not us */
-        if (status == 0xffff)
-                return IRQ_HANDLED;         /* Hot unplug */
-        if (status & error)
-		do_some_error_handling();
-        
-	do {
-/************************ start note *********************************/		
-		acknowledge_ints_ASAP();  // dont ack rx and rxnobuff here
-/************************ end note *********************************/		
-
-		if (status & link_interrupt) {
-			spin_lock(&tp->link_lock);
-			do_some_link_stat_stuff();
-			spin_unlock(&tp->link_lock);
-		}
-/************************ start note *********************************/		
-		if (status & rx_interrupt || (status & rx_nobuffs)) {
-			if (netif_rx_schedule_prep(dev)) {
-
-				/* disable interrupts caused 
-			         *	by arriving packets */
-				disable_rx_and_rxnobuff_ints();
-				/* tell system we have work to be done. */
-				__netif_rx_schedule(dev);
-			} else {
-				printk("driver bug! interrupt while in poll\n");
-				/* FIX by disabling interrupts  */
-				disable_rx_and_rxnobuff_ints();
-			}
-		}
-/************************ end note note *********************************/		
-			
-		if (status & tx_related) {
-			spin_lock(&tp->lock);
-			tx_ring_free(dev);
-
-			if (tx_died)
-				restart_tx();
-			spin_unlock(&tp->lock);
-		}
-
-		status = read_interrupt_status_reg();
-
-/************************ start note *********************************/		
-	} while (!(status & error) || more_work_to_be_done(status));
-/************************ end note note *********************************/		
-	return IRQ_HANDLED;
-}
-
----------------------------------------------------------------------
-
-
-We note several things from above:
-
-I) Any interrupt source which is caused by arriving packets is now
-turned off when it occurs. Depending on the hardware, there could be
-several reasons that arriving packets would cause interrupts; these are the
-interrupt sources we wish to avoid. The two common ones are a) a packet 
-arriving (rxint) b) a packet arriving and finding no DMA buffers available
-(rxnobuff) .
-This means also acknowledge_ints_ASAP() will not clear the status
-register for those two items above; clearing is done in the place where 
-proper work is done within NAPI; at the poll() and refill_rx_ring() 
-discussed further below.
-netif_rx_schedule_prep() returns 1 if device is in running state and
-gets successfully added to the core poll list. If we get a zero value
-we can _almost_ assume are already added to the list (instead of not running. 
-Logic based on the fact that you shouldn't get interrupt if not running)
-We rectify this by disabling rx and rxnobuf interrupts.
-
-II) that receive_packets(dev) and make_rx_buffs_avail() may have disappeared.
-These functionalities are still around actually......
-
-infact, receive_packets(dev) is very close to my_poll() and 
-make_rx_buffs_avail() is invoked from my_poll()
-
-4) converting receive_packets() to dev->poll()
-===============================================
-
-We need to convert the classical D Becker receive_packets(dev) to my_poll()
-
-First the typical receive_packets() below:
--------------------------------------------------------------------
-
-/* this is called by interrupt handler */
-static void receive_packets (struct net_device *dev)
-{
-
-	struct my_private *tp = (struct my_private *)dev->priv;
-	rx_ring = tp->rx_ring;
-	cur_rx = tp->cur_rx;
-	int entry = cur_rx % RX_RING_SIZE;
-	int received = 0;
-	int rx_work_limit = tp->dirty_rx + RX_RING_SIZE - tp->cur_rx;
-
-	while (rx_ring_not_empty) {
-		u32 rx_status;
-		unsigned int rx_size;
-		unsigned int pkt_size;
-		struct sk_buff *skb;
-                /* read size+status of next frame from DMA ring buffer */
-		/* the number 16 and 4 are just examples */
-                rx_status = le32_to_cpu (*(u32 *) (rx_ring + ring_offset));
-                rx_size = rx_status >> 16;
-                pkt_size = rx_size - 4;
-
-		/* process errors */
-                if ((rx_size > (MAX_ETH_FRAME_SIZE+4)) ||
-                    (!(rx_status & RxStatusOK))) {
-                        netdrv_rx_err (rx_status, dev, tp, ioaddr);
-                        return;
-                }
-
-                if (--rx_work_limit < 0)
-                        break;
-
-		/* grab a skb */
-                skb = dev_alloc_skb (pkt_size + 2);
-                if (skb) {
-			.
-			.
-			netif_rx (skb);
-			.
-			.
-                } else {  /* OOM */
-			/*seems very driver specific ... some just pass
-			whatever is on the ring already. */
-                }
-
-		/* move to the next skb on the ring */
-		entry = (++tp->cur_rx) % RX_RING_SIZE;
-		received++ ;
-
-        }
-
-	/* store current ring pointer state */
-        tp->cur_rx = cur_rx;
-
-        /* Refill the Rx ring buffers if they are needed */
-	refill_rx_ring();
-	.
-	.
-

-We change it to a new one below; note the additional parameter in
-the call.

-
-From above we note that:
-0) rx_work_limit = dev->quota 
-1) refill_rx_ring() is in charge of clearing the bit for rxnobuff when

-2) We have a done and not_done state.
-3) instead of netif_rx() we call netif_receive_skb() to pass the skb.
-4) we have a new way of handling oom condition
-5) A new outer for (;;) loop has been added. This serves the purpose of
-ensuring that if a new packet has come in, after we are all set and done,
-and we have not exceeded our quota that we continue sending packets up.
- 
-
------------------------------------------------------------
-Poll timer code will need to do the following:

-	
-5) dev->close() and dev->suspend() issues
-==========================================
-The driver writer needn't worry about this; the top net layer takes
-care of it.
-
-6) Adding new Stats to /proc 
-=============================
-In order to debug some of the new features, we introduce new stats
-that need to be collected.
-TODO: Fill this later.
-
-APPENDIX 1: discussion on using ethernet HW FC
-==============================================
-Most chips with FC only send a pause packet when they run out of Rx buffers.
-Since packets are pulled off the DMA ring by a softirq in NAPI,
-if the system is slow in grabbing them and we have a high input
-rate (faster than the system's capacity to remove packets), then theoretically
-there will only be one rx interrupt for all packets during a given packetstorm.
-Under low load, we might have a single interrupt per packet.
-FC should be programmed to apply in the case when the system cant pull out
-packets fast enough i.e send a pause only when you run out of rx buffers.
-Note FC in itself is a good solution but we have found it to not be
-much of a commodity feature (both in NICs and switches) and hence falls
-under the same category as using NIC based mitigation. Also, experiments
-indicate that it's much harder to resolve the resource allocation
-issue (aka lazy receiving that NAPI offers) and hence quantify its usefulness
-proved harder. In any case, FC works even better with NAPI but is not
-necessary.
-
-
-APPENDIX 2: the "rotting packet" race-window avoidance scheme 
-=============================================================
-
-There are two types of associations seen here
-
-1) status/int which honors level triggered IRQ
-
-If a status bit for receive or rxnobuff is set and the corresponding 
-interrupt-enable bit is not on, then no interrupts will be generated. However, 
-as soon as the "interrupt-enable" bit is unmasked, an immediate interrupt is 
-generated.  [assuming the status bit was not turned off].
-Generally the concept of level triggered IRQs in association with a status and
-interrupt-enable CSR register set is used to avoid the race.
-
-If we take the example of the tulip:
-"pending work" is indicated by the status bit(CSR5 in tulip).
-the corresponding interrupt bit (CSR7 in tulip) might be turned off (but
-the CSR5 will continue to be turned on with new packet arrivals even if
-we clear it the first time)
-Very important is the fact that if we turn on the interrupt bit on when
-status is set that an immediate irq is triggered.
- 
-If we cleared the rx ring and proclaimed there was "no more work
-to be done" and then went on to do a few other things;  then when we enable
-interrupts, there is a possibility that a new packet might sneak in during
-this phase. It helps to look at the pseudo code for the tulip poll
-routine:
-
---------------------------
-        do {
-                ACK;
-                while (ring_is_not_empty()) {
-                        work-work-work
-                        if quota is exceeded: exit, no touching irq status/mask
-                }
-                /* No packets, but new can arrive while we are doing this*/
-                CSR5 := read
-                if (CSR5 is not set) {
-                        /* If something arrives in this narrow window here,
-                        *  where the comments are ;-> irq will be generated */
-                        unmask irqs;
-                        exit poll;
-                }
-        } while (rx_status_is_set);
-------------------------
-
-CSR5 bit of interest is only the rx status. 
-If you look at the last if statement: 
-you just finished grabbing all the packets from the rx ring .. you check if
-status bit says there are more packets just in ... it says none; you then
-enable rx interrupts again; if a new packet just came in during this check,
-we are counting that CSR5 will be set in that small window of opportunity
-and that by re-enabling interrupts, we would actually trigger an interrupt
-to register the new packet for processing.
-
-[The above description nay be very verbose, if you have better wording 
-that will make this more understandable, please suggest it.]
-
-2) non-capable hardware
-
-These do not generally respect level triggered IRQs. Normally,
-irqs may be lost while being masked and the only way to leave poll is to do
-a double check for new input after netif_rx_complete() is invoked
-and re-enable polling (after seeing this new input).
-
-Sample code:
-
----------
-	.
-	.
-restart_poll:
-	while (ring_is_not_empty()) {
-		work-work-work
-		if quota is exceeded: exit, not touching irq status/mask
-	}
-	.
-	.
-	.
-	enable_rx_interrupts()
-	netif_rx_complete(dev);
-	if (ring_has_new_packet() && netif_rx_reschedule(dev, received)) {
-		disable_rx_and_rxnobufs()
-		goto restart_poll
-	} while (rx_status_is_set);
----------
-		
-Basically netif_rx_complete() removes us from the poll list, but because a
-new packet which will never be caught due to the possibility of a race
-might come in, we attempt to re-add ourselves to the poll list. 
-

-APPENDIX 3: Scheduling issues.
-==============================
-As seen NAPI moves processing to softirq level. Linux uses the ksoftirqd as the 
-general solution to schedule softirq's to run before next interrupt and by putting 
-them under scheduler control. Also this prevents consecutive softirq's from 
-monopolize the CPU. This also have the effect that the priority of ksoftirq needs 
-to be considered when running very CPU-intensive applications and networking to
-get the proper balance of softirq/user balance. Increasing ksoftirq priority to 0 
-(eventually more) is reported cure problems with low network performance at high 
-CPU load.
-
-Most used processes in a GIGE router:
-USER       PID %CPU %MEM  SIZE   RSS TTY STAT START   TIME COMMAND

+It also supports logging to multiple remote agents by specifying
+parameters for the multiple agents separated by semicolons and the
+complete string enclosed in "quotes", thusly:
+
+ modprobe netconsole netconsole="@/,@10.0.0.2/;@/eth1,6892@10.0.0.3/"
+
 Built-in netconsole starts immediately after the TCP stack is
 initialized and attempts to bring up the supplied dev at the supplied
 address.
 
 The remote host can run either 'netcat -u -l -p <port>' or syslogd.
 
+Dynamic reconfiguration:
+========================
+
+Dynamic reconfigurability is a useful addition to netconsole that enables
+remote logging targets to be dynamically added, removed, or have their
+parameters reconfigured at runtime from a configfs-based userspace interface.
+[ Note that the parameters of netconsole targets that were specified/created
+from the boot/module option are not exposed via this interface, and hence
+cannot be modified dynamically. ]
+
+To include this feature, select CONFIG_NETCONSOLE_DYNAMIC when building the
+netconsole module (or kernel, if netconsole is built-in).
+
+Some examples follow (where configfs is mounted at the /sys/kernel/config
+mountpoint).
+
+To add a remote logging target (target names can be arbitrary):
+
+ cd /sys/kernel/config/netconsole/
+ mkdir target1
+
+Note that newly created targets have default parameter values (as mentioned
+above) and are disabled by default -- they must first be enabled by writing
+"1" to the "enabled" attribute (usually after setting parameters accordingly)
+as described below.
+
+To remove a target:
+
+ rmdir /sys/kernel/config/netconsole/othertarget/
+
+The interface exposes these parameters of a netconsole target to userspace:
+
+	enabled		Is this target currently enabled?	(read-write)
+	dev_name	Local network interface name		(read-write)
+	local_port	Source UDP port to use			(read-write)
+	remote_port	Remote agent's UDP port			(read-write)
+	local_ip	Source IP address to use		(read-write)
+	remote_ip	Remote agent's IP address		(read-write)
+	local_mac	Local interface's MAC address		(read-only)
+	remote_mac	Remote agent's MAC address		(read-write)
+
+The "enabled" attribute is also used to control whether the parameters of
+a target can be updated or not -- you can modify the parameters of only
+disabled targets (i.e. if "enabled" is 0).
+
+To update a target's parameters:
+
+ cat enabled				# check if enabled is 1
+ echo 0 > enabled			# disable the target (if required)
+ echo eth2 > dev_name			# set local interface
+ echo 10.0.0.4 > remote_ip		# update some parameter
+ echo cb:a9:87:65:43:21 > remote_mac	# update more parameters
+ echo 1 > enabled			# enable target again
+
+You can also update the local interface dynamically. This is especially
+useful if you want to use interfaces that have newly come up (and may not
+have existed when netconsole was loaded / initialized).
+
+Miscellaneous notes:
+====================
+
 WARNING: the default target ethernet setting uses the broadcast
 ethernet address to send packets, which can cause increased load on
 other systems on the same ethernet segment.
 
+TIP: some LAN switches may be configured to suppress ethernet broadcasts
+so it is advised to explicitly specify the remote agents' MAC addresses
+from the config parameters passed to netconsole.
+
+TIP: to find out the MAC address of, say, 10.0.0.2, you may try using:
+
+ ping -c 1 10.0.0.2 ; /sbin/arp -n | grep 10.0.0.2
+
+TIP: in case the remote logging agent is on a separate LAN subnet than
+the sender, it is suggested to try specifying the MAC address of the
+default gateway (you may use /sbin/route -n to find it out) as the
+remote MAC address instead.
+
 NOTE: the network device (eth1 in the above case) can run any kind
 of other network traffic, netconsole is not intrusive. Netconsole
 might cause slight delays in other traffic if the volume of kernel
 messages is high, but should have no other impact.
 
+NOTE: if you find that the remote logging agent is not receiving or
+printing all messages from the sender, it is likely that you have set
+the "console_loglevel" parameter (on the sender) to only send high
+priority messages to the console. You can change this at runtime using:
+
+ dmesg -n 8
+
+or by specifying "debug" on the kernel command line at boot, to send
+all kernel messages to the console. A specific value for this parameter
+can also be set using the "loglevel" kernel boot option. See the
+dmesg(8) man page and Documentation/kernel-parameters.txt for details.
+
 Netconsole was designed to be as instantaneous as possible, to
 enable the logging of even the most critical kernel bugs. It works
 from IRQ contexts as well, and does not enable interrupts while

+    are defined:
+
+     - vendor-id : Contains the flash chip's vendor id (1 byte).
+     - device-id : Contains the flash chip's device id (1 byte).
+
+    In addition to the information on the flash bank itself, the
+    device tree may optionally contain additional information
+    describing partitions of the flash address space.  This can be
+    used on platforms which have strong conventions about which
+    portions of the flash are used for what purposes, but which don't
+    use an on-flash partition table such as RedBoot.
+
+    Each partition is represented as a sub-node of the flash device.
+    Each node's name represents the name of the corresponding
+    partition of the flash device.
+
+    Flash partitions
+     - reg : The partition's offset and size within the flash bank.
+     - label : (optional) The label / name for this flash partition.
+       If omitted, the label is taken from the node name (excluding
+       the unit address).
+     - read-only : (optional) This parameter, if present, is a hint to
+       Linux that this flash partition should only be mounted
+       read-only.  This is usually used for flash partitions
+       containing early-boot firmware images or data which should not
+       be clobbered.

+
+   viii) Multi-User RAM (MURAM)
+
+   The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
+
+   Ranges must be set up subject to the following restrictions:
+
+   - Children's reg nodes must be offsets from the start of all muram, even
+     if the user-data area does not begin at zero.
+   - If multiple range entries are used, the difference between the parent
+     address and the child address must be the same in all, so that a single
+     mapping can cover them all while maintaining the ability to determine
+     CPM-side offsets with pointer subtraction.  It is recommended that
+     multiple range entries not be used.
+   - A child address of zero must be translatable, even if no reg resources
+     contain it.
+
+   A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
+   indicate the portion of muram that is usable by the OS for arbitrary
+   purposes.  The data node may have an arbitrary number of reg resources,
+   all of which contribute to the allocatable muram pool.
+
+   Example, based on mpc8272:
+
+	muram@0 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		ranges = <0 0 10000>;
+
+		data@0 {
+			compatible = "fsl,cpm-muram-data";
+			reg = <0 2000 9800 800>;
+		};
+	};
+
+   m) Chipselect/Local Bus
+
+   Properties:
+   - name : Should be localbus
+   - #address-cells : Should be either two or three.  The first cell is the
+                      chipselect number, and the remaining cells are the
+                      offset into the chipselect.
+   - #size-cells : Either one or two, depending on how large each chipselect
+                   can be.
+   - ranges : Each range corresponds to a single chipselect, and cover
+              the entire access window as configured.
+
+   Example:
+	localbus@f0010100 {
+		compatible = "fsl,mpc8272ads-localbus",
+		             "fsl,mpc8272-localbus",
+		             "fsl,pq2-localbus";
+		#address-cells = <2>;
+		#size-cells = <1>;
+		reg = <f0010100 40>;
+
+		ranges = <0 0 fe000000 02000000
+		          1 0 f4500000 00008000>;
+
+		flash@0,0 {
+			compatible = "jedec-flash";
+			reg = <0 0 2000000>;
+			bank-width = <4>;
+			device-width = <1>;
+		};
+
+		board-control@1,0 {
+			reg = <1 0 20>;
+			compatible = "fsl,mpc8272ads-bcsr";
+		};
+	};
+
+
+    n) 4xx/Axon EMAC ethernet nodes
+
+    The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
+    the Axon bridge.  To operate this needs to interact with a ths
+    special McMAL DMA controller, and sometimes an RGMII or ZMII
+    interface.  In addition to the nodes and properties described
+    below, the node for the OPB bus on which the EMAC sits must have a
+    correct clock-frequency property.

+    - interrupts        : <interrupt mapping for EMAC IRQ and WOL IRQ>
+    - interrupt-parent  : optional, if needed for interrupt mapping

+			  Fox Axon: present, whatever value is appropriate for each
+			  EMAC, that is the content of the current (bogus) "phy-port"
+			  property.
+
+    Recommended properties:
+    - linux,network-index : This is the intended "index" of this

+rfkill - RF switch subsystem support
+====================================
+
+1 Implementation details
+2 Driver support
+3 Userspace support
+
+===============================================================================
+1: Implementation details
+
+The rfkill switch subsystem offers support for keys often found on laptops
+to enable wireless devices like WiFi and Bluetooth.
+
+This is done by providing the user 3 possibilities:
+ 1 - The rfkill system handles all events; userspace is not aware of events.
+ 2 - The rfkill system handles all events; userspace is informed about the events.
+ 3 - The rfkill system does not handle events; userspace handles all events.
+
+The buttons to enable and disable the wireless radios are important in
+situations where the user is for example using his laptop on a location where
+wireless radios _must_ be disabled (e.g. airplanes).
+Because of this requirement, userspace support for the keys should not be
+made mandatory. Because userspace might want to perform some additional smarter
+tasks when the key is pressed, rfkill still provides userspace the possibility
+to take over the task to handle the key events.
+
+The system inside the kernel has been split into 2 separate sections:
+	1 - RFKILL
+	2 - RFKILL_INPUT
+
+The first option enables rfkill support and will make sure userspace will
+be notified of any events through the input device. It also creates several
+sysfs entries which can be used by userspace. See section "Userspace support".
+
+The second option provides an rfkill input handler. This handler will
+listen to all rfkill key events and will toggle the radio accordingly.
+With this option enabled userspace could either do nothing or simply
+perform monitoring tasks.
+
+====================================
+2: Driver support
+
+To build a driver with rfkill subsystem support, the driver should
+depend on the Kconfig symbol RFKILL; it should _not_ depend on
+RKFILL_INPUT.
+
+Unless key events trigger an interrupt to which the driver listens, polling
+will be required to determine the key state changes. For this the input
+layer providers the input-polldev handler.
+
+A driver should implement a few steps to correctly make use of the
+rfkill subsystem. First for non-polling drivers:
+
+	- rfkill_allocate()
+	- input_allocate_device()
+	- rfkill_register()
+	- input_register_device()
+
+For polling drivers:
+
+	- rfkill_allocate()
+	- input_allocate_polled_device()
+	- rfkill_register()
+	- input_register_polled_device()
+
+When a key event has been detected, the correct event should be
+sent over the input device which has been registered by the driver.
+
+====================================
+3: Userspace support
+
+For each key an input device will be created which will send out the correct
+key event when the rfkill key has been pressed.
+
+The following sysfs entries will be created:
+
+	name: Name assigned by driver to this key (interface or driver name).
+	type: Name of the key type ("wlan", "bluetooth", etc).
+	state: Current state of the key. 1: On, 0: Off.
+	claim: 1: Userspace handles events, 0: Kernel handles events
+
+Both the "state" and "claim" entries are also writable. For the "state" entry
+this means that when 1 or 0 is written all radios, not yet in the requested
+state, will be will be toggled accordingly.
+For the "claim" entry writing 1 to it means that the kernel no longer handles
+key events even though RFKILL_INPUT input was enabled. When "claim" has been
+set to 0, userspace should make sure that it listens for the input events or
+check the sysfs "state" entry regularly to correctly perform the required
+tasks when the rkfill key is pressed.

+
+Authorizing (or not) your USB devices to connect to the system
+
+(C) 2007 Inaky Perez-Gonzalez <inaky@linux.intel.com> Intel Corporation
+
+This feature allows you to control if a USB device can be used (or
+not) in a system. This feature will allow you to implement a lock-down
+of USB devices, fully controlled by user space.
+
+As of now, when a USB device is connected it is configured and
+it's interfaces inmediately made available to the users. With this
+modification, only if root authorizes the device to be configured will
+then it be possible to use it.
+
+Usage:
+
+Authorize a device to connect:
+
+$ echo 1 > /sys/usb/devices/DEVICE/authorized
+
+Deauthorize a device:
+
+$ echo 0 > /sys/usb/devices/DEVICE/authorized
+
+Set new devices connected to hostX to be deauthorized by default (ie:
+lock down):
+
+$ echo 0 > /sys/bus/devices/usbX/authorized_default
+
+Remove the lock down:
+
+$ echo 1 > /sys/bus/devices/usbX/authorized_default
+
+By default, Wired USB devices are authorized by default to
+connect. Wireless USB hosts deauthorize by default all new connected
+devices (this is so because we need to do an authentication phase
+before authorizing).
+
+
+Example system lockdown (lame)
+-----------------------
+
+Imagine you want to implement a lockdown so only devices of type XYZ
+can be connected (for example, it is a kiosk machine with a visible
+USB port):
+
+boot up
+rc.local ->
+
+ for host in /sys/bus/devices/usb*
+ do
+    echo 0 > $host/authorized_default
+ done
+
+Hookup an script to udev, for new USB devices
+
+ if device_is_my_type $DEV
+ then
+   echo 1 > $device_path/authorized
+ done
+
+
+Now, device_is_my_type() is where the juice for a lockdown is. Just
+checking if the class, type and protocol match something is the worse
+security verification you can make (or the best, for someone willing
+to break it). If you need something secure, use crypto and Certificate
+Authentication or stuff like that. Something simple for an storage key
+could be:
+
+function device_is_my_type()
+{
+   echo 1 > authorized		# temporarily authorize it
+                                # FIXME: make sure none can mount it
+   mount DEVICENODE /mntpoint
+   sum=$(md5sum /mntpoint/.signature)
+   if [ $sum = $(cat /etc/lockdown/keysum) ]
+   then
+        echo "We are good, connected"
+        umount /mntpoint
+        # Other stuff so others can use it
+   else
+        echo 0 > authorized
+   fi
+}
+
+
+Of course, this is lame, you'd want to do a real certificate
+verification stuff with PKI, so you don't depend on a shared secret,
+etc, but you get the idea. Anybody with access to a device gadget kit
+can fake descriptors and device info. Don't trust that. You are
+welcome.

+			Power Management for USB
+
+		 Alan Stern <stern@rowland.harvard.edu>
+
+			    October 5, 2007
+
+
+
+	What is Power Management?
+	-------------------------
+
+Power Management (PM) is the practice of saving energy by suspending
+parts of a computer system when they aren't being used.  While a
+component is "suspended" it is in a nonfunctional low-power state; it
+might even be turned off completely.  A suspended component can be
+"resumed" (returned to a functional full-power state) when the kernel
+needs to use it.  (There also are forms of PM in which components are
+placed in a less functional but still usable state instead of being
+suspended; an example would be reducing the CPU's clock rate.  This
+document will not discuss those other forms.)
+
+When the parts being suspended include the CPU and most of the rest of
+the system, we speak of it as a "system suspend".  When a particular
+device is turned off while the system as a whole remains running, we
+call it a "dynamic suspend" (also known as a "runtime suspend" or
+"selective suspend").  This document concentrates mostly on how
+dynamic PM is implemented in the USB subsystem, although system PM is
+covered to some extent (see Documentation/power/*.txt for more
+information about system PM).
+
+Note: Dynamic PM support for USB is present only if the kernel was
+built with CONFIG_USB_SUSPEND enabled.  System PM support is present
+only if the kernel was built with CONFIG_SUSPEND or CONFIG_HIBERNATION
+enabled.
+
+
+	What is Remote Wakeup?
+	----------------------
+
+When a device has been suspended, it generally doesn't resume until
+the computer tells it to.  Likewise, if the entire computer has been
+suspended, it generally doesn't resume until the user tells it to, say
+by pressing a power button or opening the cover.
+
+However some devices have the capability of resuming by themselves, or
+asking the kernel to resume them, or even telling the entire computer
+to resume.  This capability goes by several names such as "Wake On
+LAN"; we will refer to it generically as "remote wakeup".  When a
+device is enabled for remote wakeup and it is suspended, it may resume
+itself (or send a request to be resumed) in response to some external
+event.  Examples include a suspended keyboard resuming when a key is
+pressed, or a suspended USB hub resuming when a device is plugged in.
+
+
+	When is a USB device idle?
+	--------------------------
+
+A device is idle whenever the kernel thinks it's not busy doing
+anything important and thus is a candidate for being suspended.  The
+exact definition depends on the device's driver; drivers are allowed
+to declare that a device isn't idle even when there's no actual
+communication taking place.  (For example, a hub isn't considered idle
+unless all the devices plugged into that hub are already suspended.)
+In addition, a device isn't considered idle so long as a program keeps
+its usbfs file open, whether or not any I/O is going on.
+
+If a USB device has no driver, its usbfs file isn't open, and it isn't
+being accessed through sysfs, then it definitely is idle.
+
+
+	Forms of dynamic PM
+	-------------------
+
+Dynamic suspends can occur in two ways: manual and automatic.
+"Manual" means that the user has told the kernel to suspend a device,
+whereas "automatic" means that the kernel has decided all by itself to
+suspend a device.  Automatic suspend is called "autosuspend" for
+short.  In general, a device won't be autosuspended unless it has been
+idle for some minimum period of time, the so-called idle-delay time.
+
+Of course, nothing the kernel does on its own initiative should
+prevent the computer or its devices from working properly.  If a
+device has been autosuspended and a program tries to use it, the
+kernel will automatically resume the device (autoresume).  For the
+same reason, an autosuspended device will usually have remote wakeup
+enabled, if the device supports remote wakeup.
+
+It is worth mentioning that many USB drivers don't support
+autosuspend.  In fact, at the time of this writing (Linux 2.6.23) the
+only drivers which do support it are the hub driver, kaweth, asix,
+usblp, usblcd, and usb-skeleton (which doesn't count).  If a
+non-supporting driver is bound to a device, the device won't be
+autosuspended.  In effect, the kernel pretends the device is never
+idle.
+
+We can categorize power management events in two broad classes:
+external and internal.  External events are those triggered by some
+agent outside the USB stack: system suspend/resume (triggered by
+userspace), manual dynamic suspend/resume (also triggered by
+userspace), and remote wakeup (triggered by the device).  Internal
+events are those triggered within the USB stack: autosuspend and
+autoresume.
+
+
+	The user interface for dynamic PM
+	---------------------------------
+
+The user interface for controlling dynamic PM is located in the power/
+subdirectory of each USB device's sysfs directory, that is, in
+/sys/bus/usb/devices/.../power/ where "..." is the device's ID.  The
+relevant attribute files are: wakeup, level, and autosuspend.
+
+	power/wakeup
+
+		This file is empty if the device does not support
+		remote wakeup.  Otherwise the file contains either the
+		word "enabled" or the word "disabled", and you can
+		write those words to the file.  The setting determines
+		whether or not remote wakeup will be enabled when the
+		device is next suspended.  (If the setting is changed
+		while the device is suspended, the change won't take
+		effect until the following suspend.)
+
+	power/level
+
+		This file contains one of three words: "on", "auto",
+		or "suspend".  You can write those words to the file
+		to change the device's setting.
+
+		"on" means that the device should be resumed and
+		autosuspend is not allowed.  (Of course, system
+		suspends are still allowed.)
+
+		"auto" is the normal state in which the kernel is
+		allowed to autosuspend and autoresume the device.
+
+		"suspend" means that the device should remain
+		suspended, and autoresume is not allowed.  (But remote
+		wakeup may still be allowed, since it is controlled
+		separately by the power/wakeup attribute.)
+
+	power/autosuspend
+
+		This file contains an integer value, which is the
+		number of seconds the device should remain idle before
+		the kernel will autosuspend it (the idle-delay time).
+		The default is 2.  0 means to autosuspend as soon as
+		the device becomes idle, and -1 means never to
+		autosuspend.  You can write a number to the file to
+		change the autosuspend idle-delay time.
+
+Writing "-1" to power/autosuspend and writing "on" to power/level do
+essentially the same thing -- they both prevent the device from being
+autosuspended.  Yes, this is a redundancy in the API.
+
+(In 2.6.21 writing "0" to power/autosuspend would prevent the device
+from being autosuspended; the behavior was changed in 2.6.22.  The
+power/autosuspend attribute did not exist prior to 2.6.21, and the
+power/level attribute did not exist prior to 2.6.22.)
+
+
+	Changing the default idle-delay time
+	------------------------------------
+
+The default autosuspend idle-delay time is controlled by a module
+parameter in usbcore.  You can specify the value when usbcore is
+loaded.  For example, to set it to 5 seconds instead of 2 you would
+do:
+
+	modprobe usbcore autosuspend=5
+
+Equivalently, you could add to /etc/modprobe.conf a line saying:
+
+	options usbcore autosuspend=5
+
+Some distributions load the usbcore module very early during the boot
+process, by means of a program or script running from an initramfs
+image.  To alter the parameter value you would have to rebuild that
+image.
+
+If usbcore is compiled into the kernel rather than built as a loadable
+module, you can add
+
+	usbcore.autosuspend=5
+
+to the kernel's boot command line.
+
+Finally, the parameter value can be changed while the system is
+running.  If you do:
+
+	echo 5 >/sys/module/usbcore/parameters/autosuspend
+
+then each new USB device will have its autosuspend idle-delay
+initialized to 5.  (The idle-delay values for already existing devices
+will not be affected.)
+
+Setting the initial default idle-delay to -1 will prevent any
+autosuspend of any USB device.  This is a simple alternative to
+disabling CONFIG_USB_SUSPEND and rebuilding the kernel, and it has the
+added benefit of allowing you to enable autosuspend for selected
+devices.
+
+
+	Warnings
+	--------
+
+The USB specification states that all USB devices must support power
+management.  Nevertheless, the sad fact is that many devices do not
+support it very well.  You can suspend them all right, but when you
+try to resume them they disconnect themselves from the USB bus or
+they stop working entirely.  This seems to be especially prevalent
+among printers and scanners, but plenty of other types of device have
+the same deficiency.
+
+For this reason, by default the kernel disables autosuspend (the
+power/level attribute is initialized to "on") for all devices other
+than hubs.  Hubs, at least, appear to be reasonably well-behaved in
+this regard.
+
+(In 2.6.21 and 2.6.22 this wasn't the case.  Autosuspend was enabled
+by default for almost all USB devices.  A number of people experienced
+problems as a result.)
+
+This means that non-hub devices won't be autosuspended unless the user
+or a program explicitly enables it.  As of this writing there aren't
+any widespread programs which will do this; we hope that in the near
+future device managers such as HAL will take on this added
+responsibility.  In the meantime you can always carry out the
+necessary operations by hand or add them to a udev script.  You can
+also change the idle-delay time; 2 seconds is not the best choice for
+every device.
+
+Sometimes it turns out that even when a device does work okay with
+autosuspend there are still problems.  For example, there are
+experimental patches adding autosuspend support to the usbhid driver,
+which manages keyboards and mice, among other things.  Tests with a
+number of keyboards showed that typing on a suspended keyboard, while
+causing the keyboard to do a remote wakeup all right, would
+nonetheless frequently result in lost keystrokes.  Tests with mice
+showed that some of them would issue a remote-wakeup request in
+response to button presses but not to motion, and some in response to
+neither.
+
+The kernel will not prevent you from enabling autosuspend on devices
+that can't handle it.  It is even possible in theory to damage a
+device by suspending it at the wrong time -- for example, suspending a
+USB hard disk might cause it to spin down without parking the heads.
+(Highly unlikely, but possible.)  Take care.
+
+
+	The driver interface for Power Management
+	-----------------------------------------
+
+The requirements for a USB driver to support external power management
+are pretty modest; the driver need only define
+
+	.suspend
+	.resume
+	.reset_resume
+
+methods in its usb_driver structure, and the reset_resume method is
+optional.  The methods' jobs are quite simple:
+
+	The suspend method is called to warn the driver that the
+	device is going to be suspended.  If the driver returns a
+	negative error code, the suspend will be aborted.  Normally
+	the driver will return 0, in which case it must cancel all
+	outstanding URBs (usb_kill_urb()) and not submit any more.
+
+	The resume method is called to tell the driver that the
+	device has been resumed and the driver can return to normal
+	operation.  URBs may once more be submitted.
+
+	The reset_resume method is called to tell the driver that
+	the device has been resumed and it also has been reset.
+	The driver should redo any necessary device initialization,
+	since the device has probably lost most or all of its state
+	(although the interfaces will be in the same altsettings as
+	before the suspend).
+
+The reset_resume method is used by the USB Persist facility (see
+Documentation/usb/persist.txt) and it can also be used under certain
+circumstances when CONFIG_USB_PERSIST is not enabled.  Currently, if a
+device is reset during a resume and the driver does not have a
+reset_resume method, the driver won't receive any notification about
+the resume.  Later kernels will call the driver's disconnect method;
+2.6.23 doesn't do this.
+
+USB drivers are bound to interfaces, so their suspend and resume
+methods get called when the interfaces are suspended or resumed.  In
+principle one might want to suspend some interfaces on a device (i.e.,
+force the drivers for those interface to stop all activity) without
+suspending the other interfaces.  The USB core doesn't allow this; all
+interfaces are suspended when the device itself is suspended and all
+interfaces are resumed when the device is resumed.  It isn't possible
+to suspend or resume some but not all of a device's interfaces.  The
+closest you can come is to unbind the interfaces' drivers.
+
+
+	The driver interface for autosuspend and autoresume
+	---------------------------------------------------
+
+To support autosuspend and autoresume, a driver should implement all
+three of the methods listed above.  In addition, a driver indicates
+that it supports autosuspend by setting the .supports_autosuspend flag
+in its usb_driver structure.  It is then responsible for informing the
+USB core whenever one of its interfaces becomes busy or idle.  The
+driver does so by calling these three functions:
+
+	int  usb_autopm_get_interface(struct usb_interface *intf);
+	void usb_autopm_put_interface(struct usb_interface *intf);
+	int  usb_autopm_set_interface(struct usb_interface *intf);
+
+The functions work by maintaining a counter in the usb_interface
+structure.  When intf->pm_usage_count is > 0 then the interface is
+deemed to be busy, and the kernel will not autosuspend the interface's
+device.  When intf->pm_usage_count is <= 0 then the interface is
+considered to be idle, and the kernel may autosuspend the device.
+
+(There is a similar pm_usage_count field in struct usb_device,
+associated with the device itself rather than any of its interfaces.
+This field is used only by the USB core.)
+
+The driver owns intf->pm_usage_count; it can modify the value however
+and whenever it likes.  A nice aspect of the usb_autopm_* routines is
+that the changes they make are protected by the usb_device structure's
+PM mutex (udev->pm_mutex); however drivers may change pm_usage_count
+without holding the mutex.
+
+	usb_autopm_get_interface() increments pm_usage_count and
+	attempts an autoresume if the new value is > 0 and the
+	device is suspended.
+
+	usb_autopm_put_interface() decrements pm_usage_count and
+	attempts an autosuspend if the new value is <= 0 and the
+	device isn't suspended.
+
+	usb_autopm_set_interface() leaves pm_usage_count alone.
+	It attempts an autoresume if the value is > 0 and the device
+	is suspended, and it attempts an autosuspend if the value is
+	<= 0 and the device isn't suspended.
+
+There also are a couple of utility routines drivers can use:
+
+	usb_autopm_enable() sets pm_usage_cnt to 1 and then calls
+	usb_autopm_set_interface(), which will attempt an autoresume.
+
+	usb_autopm_disable() sets pm_usage_cnt to 0 and then calls
+	usb_autopm_set_interface(), which will attempt an autosuspend.
+
+The conventional usage pattern is that a driver calls
+usb_autopm_get_interface() in its open routine and
+usb_autopm_put_interface() in its close or release routine.  But
+other patterns are possible.
+
+The autosuspend attempts mentioned above will often fail for one
+reason or another.  For example, the power/level attribute might be
+set to "on", or another interface in the same device might not be
+idle.  This is perfectly normal.  If the reason for failure was that
+the device hasn't been idle for long enough, a delayed workqueue
+routine is automatically set up to carry out the operation when the
+autosuspend idle-delay has expired.
+
+Autoresume attempts also can fail.  This will happen if power/level is
+set to "suspend" or if the device doesn't manage to resume properly.
+Unlike autosuspend, there's no delay for an autoresume.
+
+
+	Other parts of the driver interface
+	-----------------------------------
+
+Sometimes a driver needs to make sure that remote wakeup is enabled
+during autosuspend.  For example, there's not much point
+autosuspending a keyboard if the user can't cause the keyboard to do a
+remote wakeup by typing on it.  If the driver sets
+intf->needs_remote_wakeup to 1, the kernel won't autosuspend the
+device if remote wakeup isn't available or has been disabled through
+the power/wakeup attribute.  (If the device is already autosuspended,
+though, setting this flag won't cause the kernel to autoresume it.
+Normally a driver would set this flag in its probe method, at which
+time the device is guaranteed not to be autosuspended.)
+
+The usb_autopm_* routines have to run in a sleepable process context;
+they must not be called from an interrupt handler or while holding a
+spinlock.  In fact, the entire autosuspend mechanism is not well geared
+toward interrupt-driven operation.  However there is one thing a
+driver can do in an interrupt handler:
+
+	usb_mark_last_busy(struct usb_device *udev);
+
+This sets udev->last_busy to the current time.  udev->last_busy is the
+field used for idle-delay calculations; updating it will cause any
+pending autosuspend to be moved back.  The usb_autopm_* routines will
+also set the last_busy field to the current time.
+
+Calling urb_mark_last_busy() from within an URB completion handler is
+subject to races: The kernel may have just finished deciding the
+device has been idle for long enough but not yet gotten around to
+calling the driver's suspend method.  The driver would have to be
+responsible for synchronizing its suspend method with its URB
+completion handler and causing the autosuspend to fail with -EBUSY if
+an URB had completed too recently.
+
+External suspend calls should never be allowed to fail in this way,
+only autosuspend calls.  The driver can tell them apart by checking
+udev->auto_pm; this flag will be set to 1 for internal PM events
+(autosuspend or autoresume) and 0 for external PM events.
+
+Many of the ingredients in the autosuspend framework are oriented
+towards interfaces: The usb_interface structure contains the
+pm_usage_cnt field, and the usb_autopm_* routines take an interface
+pointer as their argument.  But somewhat confusingly, a few of the
+pieces (usb_mark_last_busy() and udev->auto_pm) use the usb_device
+structure instead.  Drivers need to keep this straight; they can call
+interface_to_usbdev() to find the device structure for a given
+interface.
+
+
+	Locking requirements
+	--------------------
+
+All three suspend/resume methods are always called while holding the
+usb_device's PM mutex.  For external events -- but not necessarily for
+autosuspend or autoresume -- the device semaphore (udev->dev.sem) will
+also be held.  This implies that external suspend/resume events are
+mutually exclusive with calls to probe, disconnect, pre_reset, and
+post_reset; the USB core guarantees that this is true of internal
+suspend/resume events as well.
+
+If a driver wants to block all suspend/resume calls during some
+critical section, it can simply acquire udev->pm_mutex.
+Alternatively, if the critical section might call some of the
+usb_autopm_* routines, the driver can avoid deadlock by doing:
+
+	down(&udev->dev.sem);
+	rc = usb_autopm_get_interface(intf);
+
+and at the end of the critical section:
+
+	if (!rc)
+		usb_autopm_put_interface(intf);
+	up(&udev->dev.sem);
+
+Holding the device semaphore will block all external PM calls, and the
+usb_autopm_get_interface() will prevent any internal PM calls, even if
+it fails.  (Exercise: Why?)
+
+The rules for locking order are:
+
+	Never acquire any device semaphore while holding any PM mutex.
+
+	Never acquire udev->pm_mutex while holding the PM mutex for
+	a device that isn't a descendant of udev.
+
+In other words, PM mutexes should only be acquired going up the device
+tree, and they should be acquired only after locking all the device
+semaphores you need to hold.  These rules don't matter to drivers very
+much; they usually affect just the USB core.
+
+Still, drivers do need to be careful.  For example, many drivers use a
+private mutex to synchronize their normal I/O activities with their
+disconnect method.  Now if the driver supports autosuspend then it
+must call usb_autopm_put_interface() from somewhere -- maybe from its
+close method.  It should make the call while holding the private mutex,
+since a driver shouldn't call any of the usb_autopm_* functions for an
+interface from which it has been unbound.
+
+But the usb_autpm_* routines always acquire the device's PM mutex, and
+consequently the locking order has to be: private mutex first, PM
+mutex second.  Since the suspend method is always called with the PM
+mutex held, it mustn't try to acquire the private mutex.  It has to
+synchronize with the driver's I/O activities in some other way.
+
+
+	Interaction between dynamic PM and system PM
+	--------------------------------------------
+
+Dynamic power management and system power management can interact in
+a couple of ways.
+
+Firstly, a device may already be manually suspended or autosuspended
+when a system suspend occurs.  Since system suspends are supposed to
+be as transparent as possible, the device should remain suspended
+following the system resume.  The 2.6.23 kernel obeys this principle
+for manually suspended devices but not for autosuspended devices; they
+do get resumed when the system wakes up.  (Presumably they will be
+autosuspended again after their idle-delay time expires.)  In later
+kernels this behavior will be fixed.
+
+(There is an exception.  If a device would undergo a reset-resume
+instead of a normal resume, and the device is enabled for remote
+wakeup, then the reset-resume takes place even if the device was
+already suspended when the system suspend began.  The justification is
+that a reset-resume is a kind of remote-wakeup event.  Or to put it
+another way, a device which needs a reset won't be able to generate
+normal remote-wakeup signals, so it ought to be resumed immediately.)
+
+Secondly, a dynamic power-management event may occur as a system
+suspend is underway.  The window for this is short, since system
+suspends don't take long (a few seconds usually), but it can happen.
+For example, a suspended device may send a remote-wakeup signal while
+the system is suspending.  The remote wakeup may succeed, which would
+cause the system suspend to abort.  If the remote wakeup doesn't
+succeed, it may still remain active and thus cause the system to
+resume as soon as the system suspend is complete.  Or the remote
+wakeup may fail and get lost.  Which outcome occurs depends on timing
+and on the hardware and firmware design.
+
+More interestingly, a device might undergo a manual resume or
+autoresume during system suspend.  With current kernels this shouldn't
+happen, because manual resumes must be initiated by userspace and
+autoresumes happen in response to I/O requests, but all user processes
+and I/O should be quiescent during a system suspend -- thanks to the
+freezer.  However there are plans to do away with the freezer, which
+would mean these things would become possible.  If and when this comes
+about, the USB core will carefully arrange matters so that either type
+of resume will block until the entire system has resumed.

- *         screen-blanking and gpm (Stephen Rothwell); Linux 1.99.4
- *    1.2a:Simple change to stop mysterious bug reports with SMP also added
- *	   levels to the printk calls. APM is not defined for SMP machines.

- *         Stephen Rothwell
- *    1.7: Modify driver's cached copy of the disabled/disengaged flags
- *         to reflect current state of APM BIOS.
- *         Chris Rankin <rankinc@bellsouth.net>
- *         Reset interrupt 0 timer to 100Hz after suspend

- *         Try to cope with BIOS's that need to have all display
- *         devices blanked and not just the first one.
- *         Ross Paterson <ross@soi.city.ac.uk>
- *         Fix segment limit setting it has always been wrong as
- *         the segments needed to have byte granularity.
- *         Mark a few things __init.
- *         Add hack to allow power off of SMP systems by popular request.
- *         Use CONFIG_SMP instead of __SMP__
- *         Ignore BOUNCES for three seconds.
- *         Stephen Rothwell
- *   1.10: Fix for Thinkpad return code.
- *         Merge 2.2 and 2.3 drivers.

- *         configurable (default on).
- *         Make debug only a boot time parameter (remove APM_DEBUG).
- *         Try to blank all devices on any error.
- *   1.11: Remove APM dependencies in drivers/char/console.c
- *         Check nr_running to detect if we are idle (from
- *         Borislav Deianov <borislav@lix.polytechnique.fr>)
- *         Fix for bioses that don't zero the top part of the
- *         entrypoint offset (Mario Sitta <sitta@al.unipmn.it>)
- *         (reported by Panos Katsaloulis <teras@writeme.com>).
- *         Real mode power off patch (Walter Hofmann
- *         <Walter.Hofmann@physik.stud.uni-erlangen.de>).
- *   1.12: Remove CONFIG_SMP as the compiler will optimize
- *         the code away anyway (smp_num_cpus == 1 in UP)
- *         noted by Artur Skawina <skawina@geocities.com>.
- *         Make power off under SMP work again.
- *         Fix thinko with initial engaging of BIOS.
- *         Make sure power off only happens on CPU 0
- *         (Paul "Rusty" Russell <rusty@rustcorp.com.au>).
- *         Do error notification to user mode if BIOS calls fail.
- *         Move entrypoint offset fix to ...boot/setup.S
- *         where it belongs (Cosmos <gis88564@cis.nctu.edu.tw>).
- *         Remove smp-power-off. SMP users must now specify
- *         "apm=power-off" on the kernel command line. Suggested
- *         by Jim Avera <jima@hal.com>, modified by Alan Cox
- *         <alan@lxorguk.ukuu.org.uk>.
- *         Register the /proc/apm entry even on SMP so that
- *         scripts that check for it before doing power off
- *         work (Jim Avera <jima@hal.com>).
- *   1.13: Changes for new pm_ interfaces (Andy Henroid
- *         <andy_henroid@yahoo.com>).
- *         Modularize the code.
- *         Fix the Thinkpad (again) :-( (CONFIG_APM_IGNORE_MULTIPLE_SUSPENDS
- *         is now the way life works).
- *         Fix thinko in suspend() (wrong return).
- *         Notify drivers on critical suspend.
- *         Make kapmd absorb more idle time (Pavel Machek <pavel@suse.cz>
- *         modified by sfr).
- *         Disable interrupts while we are suspended (Andy Henroid
- *         <andy_henroid@yahoo.com> fixed by sfr).
- *         Make power off work on SMP again (Tony Hoyle
- *         <tmh@magenta-logic.com> and <zlatko@iskon.hr>) modified by sfr.
- *         Remove CONFIG_APM_SUSPEND_BOUNCE.  The bounce ignore
- *         interval is now configurable.
- *   1.14: Make connection version persist across module unload/load.
- *         Enable and engage power management earlier.
- *         Disengage power management on module unload.
- *         Changed to use the sysrq-register hack for registering the
- *         power off function called by magic sysrq based upon discussions
- *         in irc://irc.openprojects.net/#kernelnewbies
- *         (Crutcher Dunnavant <crutcher+kernel@datastacks.com>).
- *         Make CONFIG_APM_REAL_MODE_POWER_OFF run time configurable.
- *         (Arjan van de Ven <arjanv@redhat.com>) modified by sfr.
- *         Work around byte swap bug in one of the Vaio's BIOS's
- *         (Marc Boucher <marc@mbsi.ca>).
- *         Exposed the disable flag to dmi so that we can handle known
- *         broken APM (Alan Cox <alan@redhat.com>).
- *   1.14ac: If the BIOS says "I slowed the CPU down" then don't spin
- *         calling it - instead idle. (Alan Cox <alan@redhat.com>)
- *         If an APM idle fails log it and idle sensibly
- *   1.15: Don't queue events to clients who open the device O_WRONLY.
- *         Don't expect replies from clients who open the device O_RDONLY.
- *         (Idea from Thomas Hood)
- *         Minor waitqueue cleanups. (John Fremlin <chief@bandits.org>)
- *   1.16: Fix idle calling. (Andreas Steinmetz <ast@domdv.de> et al.)
- *         Notify listeners of standby or suspend events before notifying
- *         drivers. Return EBUSY to ioctl() if suspend is rejected.
- *         (Russell King <rmk@arm.linux.org.uk> and Thomas Hood)
- *         Ignore first resume after we generate our own resume event
- *         after a suspend (Thomas Hood)
- *         Daemonize now gets rid of our controlling terminal (sfr).
- *         CONFIG_APM_CPU_IDLE now just affects the default value of
- *         idle_threshold (sfr).
- *         Change name of kernel apm daemon (as it no longer idles) (sfr).
- *   1.16ac: Fix up SMP support somewhat. You can now force SMP on and we
- *	   make _all_ APM calls on the CPU#0. Fix unsafe sign bug.
- *	   TODO: determine if its "boot CPU" or "CPU0" we want to lock to.

- *
- * Theoritical note:
- *
- *	(see Geode(tm) CS5530 manual (rev.4.1) page.56)
- *
- *	CPU frequency control on NatSemi Geode GX1/GXLV processor and CS55x0
- *	are based on Suspend Moduration.
- *
- *	Suspend Modulation works by asserting and de-asserting the SUSP# pin
- *	to CPU(GX1/GXLV) for configurable durations. When asserting SUSP#
- *	the CPU enters an idle state. GX1 stops its core clock when SUSP# is
- *	asserted then power consumption is reduced.
- *
- *	Suspend Modulation's OFF/ON duration are configurable
- *	with 'Suspend Modulation OFF Count Register'
- *	and 'Suspend Modulation ON Count Register'.
- *	These registers are 8bit counters that represent the number of
- *	32us intervals which the SUSP# pin is asserted(ON)/de-asserted(OFF)
- *	to the processor.
- *
- *	These counters define a ratio which is the effective frequency
- *	of operation of the system.
- *
- *			       OFF Count
- *	F_eff = Fgx * ----------------------
- *	                OFF Count + ON Count
- *
- *	0 <= On Count, Off Count <= 255
- *
- *	From these limits, we can get register values
- *
- *	off_duration + on_duration <= MAX_DURATION
- *	on_duration = off_duration * (stock_freq - freq) / freq
- *
- *      off_duration  =  (freq * DURATION) / stock_freq
- *      on_duration = DURATION - off_duration
- *
- *
- *---------------------------------------------------------------------------
- *
- * ChangeLog:
- *	Dec. 12, 2003	Hiroshi Miura <miura@da-cha.org>
- *		- fix on/off register mistake
- *		- fix cpu_khz calc when it stops cpu modulation.
- *
- *	Dec. 11, 2002	Hiroshi Miura <miura@da-cha.org>
- *		- rewrite for Cyrix MediaGX Cx5510/5520 and
- *		  NatSemi Geode Cs5530(A).
- *
- *	Jul. ??, 2002  Zwane Mwaikambo <zwane@commfireservices.com>
- *		- cs5530_mod patch for 2.4.19-rc1.
- *
- *---------------------------------------------------------------------------
- *
- * Todo
- *	Test on machines with 5510, 5530, 5530A

- *  VIA have currently 3 different versions of Longhaul.
- *  Version 1 (Longhaul) uses the BCR2 MSR at 0x1147.
- *   It is present only in Samuel 1 (C5A), Samuel 2 (C5B) stepping 0.
- *  Version 2 of longhaul is backward compatible with v1, but adds
- *   LONGHAUL MSR for purpose of both frequency and voltage scaling.
- *   Present in Samuel 2 (steppings 1-7 only) (C5B), and Ezra (C5C).
- *  Version 3 of longhaul got renamed to Powersaver and redesigned
- *   to use only the POWERSAVER MSR at 0x110a.
- *   It is present in Ezra-T (C5M), Nehemiah (C5X) and above.
- *   It's pretty much the same feature wise to longhaul v2, though
- *   there is provision for scaling FSB too, but this doesn't work
- *   too well in practice so we don't even try to use this.
- *
- *  BIG FAT DISCLAIMER: Work in progress code. Possibly *dangerous*

-   followed immediately by a far jump instruction, which set CS to a
-   valid value for real mode, and flushes the prefetch queue to avoid
-   running instructions that have already been decoded in protected
-   mode.
-
-   Clears all the flags except ET, especially PG (paging), PE
-   (protected-mode enable) and TS (task switch for coprocessor state
-   save).  Flushes the TLB after paging has been disabled.  Sets CD and
-   NW, to disable the cache on a 486, and invalidates the cache.  This
-   is more like the state of a 486 after reset.  I don't know if
-   something else should be done for other chips.
-
-   More could be done here to set up the registers as if a CPU reset had
-   occurred; hopefully real BIOSs don't assume much. */

- *	- regions configured, but not enabled in the command register
- *	- bogus I/O addresses above 64K used
- *	- expansion ROMs left enabled (this may sound harmless, but given
- *	  the fact the PCI specs explicitly allow address decoders to be
- *	  shared between expansion ROMs and other resource regions, it's
- *	  at least dangerous)
- *
- *  Our solution:
- *	(1) Allocate resources for all buses behind PCI-to-PCI bridges.
- *	    This gives us fixed barriers on where we can allocate.
- *	(2) Allocate resources for all enabled devices.  If there is
- *	    a collision, just mark the resource as unallocated. Also
- *	    disable expansion ROMs during this step.
- *	(3) Try to allocate resources for disabled devices.  If the
- *	    resources were assigned correctly, everything goes well,
- *	    if they weren't, they won't disturb allocation of other
- *	    resources.
- *	(4) Assign new addresses to resources which were either
- *	    not configured at all or misconfigured.  If explicitly
- *	    requested by the user, configure expansion ROM address
- *	    as well.

- *	PIRQ routing for SiS 85C503 router used in several SiS chipsets.
- *	We have to deal with the following issues here:
- *	- vendors have different ideas about the meaning of link values
- *	- some onboard devices (integrated in the chipset) have special
- *	  links and are thus routed differently (i.e. not via PCI INTA-INTD)
- *	- different revision of the router have a different layout for
- *	  the routing registers, particularly for the onchip devices
- *
- *	For all routing registers the common thing is we have one byte
- *	per routeable link which is defined as:
- *		 bit 7      IRQ mapping enabled (0) or disabled (1)
- *		 bits [6:4] reserved (sometimes used for onchip devices)
- *		 bits [3:0] IRQ to map to
- *		     allowed: 3-7, 9-12, 14-15
- *		     reserved: 0, 1, 2, 8, 13
- *
- *	The config-space registers located at 0x41/0x42/0x43/0x44 are
- *	always used to route the normal PCI INT A/B/C/D respectively.
- *	Apparently there are systems implementing PCI routing table using
- *	link values 0x01-0x04 and others using 0x41-0x44 for PCI INTA..D.
- *	We try our best to handle both link mappings.
- *	
- *	Currently (2003-05-21) it appears most SiS chipsets follow the
- *	definition of routing registers from the SiS-5595 southbridge.
- *	According to the SiS 5595 datasheets the revision id's of the
- *	router (ISA-bridge) should be 0x01 or 0xb0.
- *
- *	Furthermore we've also seen lspci dumps with revision 0x00 and 0xb1.
- *	Looks like these are used in a number of SiS 5xx/6xx/7xx chipsets.
- *	They seem to work with the current routing code. However there is
- *	some concern because of the two USB-OHCI HCs (original SiS 5595
- *	had only one). YMMV.
- *
- *	Onchip routing for router rev-id 0x01/0xb0 and probably 0x00/0xb1:
- *
- *	0x61:	IDEIRQ:
- *		bits [6:5] must be written 01
- *		bit 4 channel-select primary (0), secondary (1)
- *
- *	0x62:	USBIRQ:
- *		bit 6 OHCI function disabled (0), enabled (1)
- *	
- *	0x6a:	ACPI/SCI IRQ: bits 4-6 reserved
- *
- *	0x7e:	Data Acq. Module IRQ - bits 4-6 reserved
- *
- *	We support USBIRQ (in addition to INTA-INTD) and keep the
- *	IDE, ACPI and DAQ routing untouched as set by the BIOS.
- *
- *	Currently the only reported exception is the new SiS 65x chipset
- *	which includes the SiS 69x southbridge. Here we have the 85C503
- *	router revision 0x04 and there are changes in the register layout
- *	mostly related to the different USB HCs with USB 2.0 support.
- *
- *	Onchip routing for router rev-id 0x04 (try-and-error observation)

+ *
+ * Software floating emuation for the MPC8xx processor.  I did this mostly
+ * because it was easier than trying to get the libraries compiled for
+ * software floating point.  The goal is still to get the libraries done,
+ * but I lost patience and needed some hacks to at least get init and
+ * shells running.  The first problem is the setjmp/longjmp that save
+ * and restore the floating point registers.
+ *
+ * For this emulation, our working registers are found on the register
+ * save area.

-	  This option supports the 2232 7-port serial card shipped with the
-	  Amiga 2000 and other Zorro-bus machines, dating from 1989.  At
-	  a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
-	  each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
-	  ports were connected with 8 pin DIN connectors on the card bracket,
-	  for which 8 pin to DB25 adapters were supplied. The card also had
-	  jumpers internally to toggle various pinning configurations.
-
-	  This driver can be built as a module; but then "generic_serial"
-	  will also be built as a module. This has to be loaded before
-	  "ser_a2232". If you want to do this, answer M here.

- * Amiga Linux interrupt handling code

- * for more details.
- *
- * 11/07/96: rewritten interrupt handling, irq lists are exists now only for
- *           this sources where it makes sense (VERTB/PORTS/EXTER) and you must
- *           be careful that dev_id for this sources is unique since this the
- *           only possibility to distinguish between different handlers for
- *           free_irq. irq lists also have different irq flags:
- *           - IRQ_FLG_FAST: handler is inserted at top of list (after other
- *                           fast handlers)
- *           - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
- *                           they're executed irq level is set to the previous
- *                           one, but handlers don't need to be reentrant, if
- *                           reentrance occurred, slow handlers will be just
- *                           called again.
- *           The whole interrupt handling for CIAs is moved to cia.c
- *           /Roman Zippel
- *
- * 07/08/99: rewamp of the interrupt handling - we now have two types of
- *           interrupts, normal and fast handlers, fast handlers being
- *           marked with SA_INTERRUPT and runs with all other interrupts
- *           disabled. Normal interrupts disable their own source but
- *           run with all other interrupt sources enabled.
- *           PORTS and EXTER interrupts are always shared even if the
- *           drivers do not explicitly mark this when calling
- *           request_irq which they really should do.
- *           This is similar to the way interrupts are handled on all
- *           other architectures and makes a ton of sense besides
- *           having the advantage of making it easier to share
- *           drivers.

+ *    1.9: Fix small typo.  <laslo@wodip.opole.pl>
+ *         Try to cope with BIOS's that need to have all display
+ *         devices blanked and not just the first one.
+ *         Ross Paterson <ross@soi.city.ac.uk>
+ *         Fix segment limit setting it has always been wrong as
+ *         the segments needed to have byte granularity.
+ *         Mark a few things __init.
+ *         Add hack to allow power off of SMP systems by popular request.
+ *         Use CONFIG_SMP instead of __SMP__
+ *         Ignore BOUNCES for three seconds.
+ *         Stephen Rothwell
+ *   1.10: Fix for Thinkpad return code.

+ *         Remove APM dependencies in drivers/char/sysrq.c
+ *         Reset time across standby.
+ *         Allow more inititialisation on SMP.
+ *         Remove CONFIG_APM_POWER_OFF and make it boot time

+ *         Make debug only a boot time parameter (remove APM_DEBUG).
+ *         Try to blank all devices on any error.
+ *   1.11: Remove APM dependencies in drivers/char/console.c
+ *         Check nr_running to detect if we are idle (from
+ *         Borislav Deianov <borislav@lix.polytechnique.fr>)
+ *         Fix for bioses that don't zero the top part of the
+ *         entrypoint offset (Mario Sitta <sitta@al.unipmn.it>)
+ *         (reported by Panos Katsaloulis <teras@writeme.com>).
+ *         Real mode power off patch (Walter Hofmann
+ *         <Walter.Hofmann@physik.stud.uni-erlangen.de>).
+ *   1.12: Remove CONFIG_SMP as the compiler will optimize
+ *         the code away anyway (smp_num_cpus == 1 in UP)
+ *         noted by Artur Skawina <skawina@geocities.com>.
+ *         Make power off under SMP work again.
+ *         Fix thinko with initial engaging of BIOS.
+ *         Make sure power off only happens on CPU 0

+ *         where it belongs (Cosmos <gis88564@cis.nctu.edu.tw>).
+ *         Remove smp-power-off. SMP users must now specify

+ *         by Jim Avera <jima@hal.com>, modified by Alan Cox
+ *         <alan@lxorguk.ukuu.org.uk>.
+ *         Register the /proc/apm entry even on SMP so that

+ *         work (Jim Avera <jima@hal.com>).
+ *   1.13: Changes for new pm_ interfaces (Andy Henroid
+ *         <andy_henroid@yahoo.com>).
+ *         Modularize the code.
+ *         Fix the Thinkpad (again) :-( (CONFIG_APM_IGNORE_MULTIPLE_SUSPENDS
+ *         is now the way life works).
+ *         Fix thinko in suspend() (wrong return).
+ *         Notify drivers on critical suspend.
+ *         Make kapmd absorb more idle time (Pavel Machek <pavel@suse.cz>
+ *         modified by sfr).
+ *         Disable interrupts while we are suspended (Andy Henroid
+ *         <andy_henroid@yahoo.com> fixed by sfr).
+ *         Make power off work on SMP again (Tony Hoyle
+ *         <tmh@magenta-logic.com> and <zlatko@iskon.hr>) modified by sfr.
+ *         Remove CONFIG_APM_SUSPEND_BOUNCE.  The bounce ignore
+ *         interval is now configurable.
+ *   1.14: Make connection version persist across module unload/load.
+ *         Enable and engage power management earlier.
+ *         Disengage power management on module unload.
+ *         Changed to use the sysrq-register hack for registering the
+ *         power off function called by magic sysrq based upon discussions
+ *         in irc://irc.openprojects.net/#kernelnewbies
+ *         (Crutcher Dunnavant <crutcher+kernel@datastacks.com>).
+ *         Make CONFIG_APM_REAL_MODE_POWER_OFF run time configurable.
+ *         (Arjan van de Ven <arjanv@redhat.com>) modified by sfr.
+ *         Work around byte swap bug in one of the Vaio's BIOS's
+ *         (Marc Boucher <marc@mbsi.ca>).
+ *         Exposed the disable flag to dmi so that we can handle known
+ *         broken APM (Alan Cox <alan@redhat.com>).
+ *   1.14ac: If the BIOS says "I slowed the CPU down" then don't spin
+ *         calling it - instead idle. (Alan Cox <alan@redhat.com>)
+ *         If an APM idle fails log it and idle sensibly
+ *   1.15: Don't queue events to clients who open the device O_WRONLY.
+ *         Don't expect replies from clients who open the device O_RDONLY.
+ *         (Idea from Thomas Hood)
+ *         Minor waitqueue cleanups. (John Fremlin <chief@bandits.org>)
+ *   1.16: Fix idle calling. (Andreas Steinmetz <ast@domdv.de> et al.)
+ *         Notify listeners of standby or suspend events before notifying
+ *         drivers. Return EBUSY to ioctl() if suspend is rejected.
+ *         (Russell King <rmk@arm.linux.org.uk> and Thomas Hood)
+ *         Ignore first resume after we generate our own resume event
+ *         after a suspend (Thomas Hood)
+ *         Daemonize now gets rid of our controlling terminal (sfr).
+ *         CONFIG_APM_CPU_IDLE now just affects the default value of
+ *         idle_threshold (sfr).
+ *         Change name of kernel apm daemon (as it no longer idles) (sfr).
+ *   1.16ac: Fix up SMP support somewhat. You can now force SMP on and we
+ *	   make _all_ APM calls on the CPU#0. Fix unsafe sign bug.
+ *	   TODO: determine if its "boot CPU" or "CPU0" we want to lock to.

+ *
+ * Theoritical note:
+ *
+ *	(see Geode(tm) CS5530 manual (rev.4.1) page.56)
+ *
+ *	CPU frequency control on NatSemi Geode GX1/GXLV processor and CS55x0
+ *	are based on Suspend Moduration.
+ *
+ *	Suspend Modulation works by asserting and de-asserting the SUSP# pin
+ *	to CPU(GX1/GXLV) for configurable durations. When asserting SUSP#
+ *	the CPU enters an idle state. GX1 stops its core clock when SUSP# is
+ *	asserted then power consumption is reduced.
+ *
+ *	Suspend Modulation's OFF/ON duration are configurable
+ *	with 'Suspend Modulation OFF Count Register'
+ *	and 'Suspend Modulation ON Count Register'.
+ *	These registers are 8bit counters that represent the number of
+ *	32us intervals which the SUSP# pin is asserted(ON)/de-asserted(OFF)
+ *	to the processor.
+ *
+ *	These counters define a ratio which is the effective frequency
+ *	of operation of the system.
+ *
+ *			       OFF Count
+ *	F_eff = Fgx * ----------------------
+ *	                OFF Count + ON Count
+ *
+ *	0 <= On Count, Off Count <= 255
+ *
+ *	From these limits, we can get register values
+ *
+ *	off_duration + on_duration <= MAX_DURATION
+ *	on_duration = off_duration * (stock_freq - freq) / freq
+ *
+ *      off_duration  =  (freq * DURATION) / stock_freq
+ *      on_duration = DURATION - off_duration
+ *
+ *
+ *---------------------------------------------------------------------------
+ *
+ * ChangeLog:
+ *	Dec. 12, 2003	Hiroshi Miura <miura@da-cha.org>
+ *		- fix on/off register mistake
+ *		- fix cpu_khz calc when it stops cpu modulation.
+ *
+ *	Dec. 11, 2002	Hiroshi Miura <miura@da-cha.org>
+ *		- rewrite for Cyrix MediaGX Cx5510/5520 and
+ *		  NatSemi Geode Cs5530(A).
+ *
+ *	Jul. ??, 2002  Zwane Mwaikambo <zwane@commfireservices.com>
+ *		- cs5530_mod patch for 2.4.19-rc1.
+ *
+ *---------------------------------------------------------------------------
+ *
+ * Todo
+ *	Test on machines with 5510, 5530, 5530A

+ *
+ *  Known BIOS problems we have to work around:

+ *	  the fact the PCI specs explicitly allow address decoders to be
+ *	  shared between expansion ROMs and other resource regions, it's
+ *	  at least dangerous)
+ *
+ *  Our solution:
+ *	(1) Allocate resources for all buses behind PCI-to-PCI bridges.
+ *	    This gives us fixed barriers on where we can allocate.
+ *	(2) Allocate resources for all enabled devices.  If there is
+ *	    a collision, just mark the resource as unallocated. Also
+ *	    disable expansion ROMs during this step.
+ *	(3) Try to allocate resources for disabled devices.  If the
+ *	    resources were assigned correctly, everything goes well,
+ *	    if they weren't, they won't disturb allocation of other
+ *	    resources.
+ *	(4) Assign new addresses to resources which were either
+ *	    not configured at all or misconfigured.  If explicitly
+ *	    requested by the user, configure expansion ROM address

+ *	PIRQ routing for SiS 85C503 router used in several SiS chipsets.
+ *	We have to deal with the following issues here:
+ *	- vendors have different ideas about the meaning of link values
+ *	- some onboard devices (integrated in the chipset) have special
+ *	  links and are thus routed differently (i.e. not via PCI INTA-INTD)
+ *	- different revision of the router have a different layout for
+ *	  the routing registers, particularly for the onchip devices
+ *
+ *	For all routing registers the common thing is we have one byte
+ *	per routeable link which is defined as:
+ *		 bit 7      IRQ mapping enabled (0) or disabled (1)
+ *		 bits [6:4] reserved (sometimes used for onchip devices)
+ *		 bits [3:0] IRQ to map to
+ *		     allowed: 3-7, 9-12, 14-15
+ *		     reserved: 0, 1, 2, 8, 13
+ *
+ *	The config-space registers located at 0x41/0x42/0x43/0x44 are
+ *	always used to route the normal PCI INT A/B/C/D respectively.
+ *	Apparently there are systems implementing PCI routing table using
+ *	link values 0x01-0x04 and others using 0x41-0x44 for PCI INTA..D.
+ *	We try our best to handle both link mappings.
+ *	
+ *	Currently (2003-05-21) it appears most SiS chipsets follow the
+ *	definition of routing registers from the SiS-5595 southbridge.
+ *	According to the SiS 5595 datasheets the revision id's of the
+ *	router (ISA-bridge) should be 0x01 or 0xb0.
+ *
+ *	Furthermore we've also seen lspci dumps with revision 0x00 and 0xb1.
+ *	Looks like these are used in a number of SiS 5xx/6xx/7xx chipsets.
+ *	They seem to work with the current routing code. However there is
+ *	some concern because of the two USB-OHCI HCs (original SiS 5595
+ *	had only one). YMMV.
+ *
+ *	Onchip routing for router rev-id 0x01/0xb0 and probably 0x00/0xb1:
+ *
+ *	0x61:	IDEIRQ:
+ *		bits [6:5] must be written 01
+ *		bit 4 channel-select primary (0), secondary (1)
+ *
+ *	0x62:	USBIRQ:
+ *		bit 6 OHCI function disabled (0), enabled (1)
+ *	
+ *	0x6a:	ACPI/SCI IRQ: bits 4-6 reserved
+ *
+ *	0x7e:	Data Acq. Module IRQ - bits 4-6 reserved
+ *
+ *	We support USBIRQ (in addition to INTA-INTD) and keep the
+ *	IDE, ACPI and DAQ routing untouched as set by the BIOS.
+ *
+ *	Currently the only reported exception is the new SiS 65x chipset
+ *	which includes the SiS 69x southbridge. Here we have the 85C503
+ *	router revision 0x04 and there are changes in the register layout
+ *	mostly related to the different USB HCs with USB 2.0 support.
+ *
+ *	Onchip routing for router rev-id 0x04 (try-and-error observation)
+ *
+ *	0x60/0x61/0x62/0x63:	1xEHCI and 3xOHCI (companion) USB-HCs
+ *				bit 6-4 are probably unused, not like 5595

- *	Trampoline.S	Derived from Setup.S by Linus Torvalds
- *
- *	4 Jan 1997 Michael Chastain: changed to gnu as.
- *	15 Sept 2005 Eric Biederman: 64bit PIC support
- *
- *	Entry: CS:IP point to the start of our code, we are 
- *	in real mode with no stack, but the rest of the 
- *	trampoline page to make our stack and everything else
- *	is a mystery.
- *
- *	In fact we don't actually need a stack so we don't
- *	set one up.
- *
- *	On entry to trampoline_data, the processor is in real mode
- *	with 16-bit addressing and 16-bit data.  CS has some value
- *	and IP is zero.  Thus, data addresses need to be absolute
- *	(no relocation) and are taken with regard to r_base.
- *
- *	With the addition of trampoline_level4_pgt this code can
- *	now enter a 64bit kernel that lives at arbitrary 64bit
- *	physical addresses.
- *
- *	If you work on this file, check the object module with objdump
- *	--full-contents --reloc to make sure there are no relocation
- *	entries.

-	  is capable of bus-master DMA operation (most Pentium PCI systems),
-	  you will want to say Y here to reduce CPU overhead. You can then use
-	  the "hdparm" utility to enable DMA for drives for which it was not
-	  enabled automatically. By default, DMA is not enabled automatically
-	  for these drives, but you can change that by saying Y to the
-	  following question "Use DMA by default when available". You can get
-	  the latest version of the hdparm utility from
-	  <ftp://ibiblio.org/pub/Linux/system/hardware/>.
-
-	  Read the comments at the beginning of <file:drivers/ide/ide-dma.c>
-	  and the file <file:Documentation/ide.txt> for more information.
-
-	  It is safe to say Y to this question.

+    On Screen Display cx23415 Framebuffer driver
+
+    This module presents the cx23415 OSD (onscreen display) framebuffer memory
+    as a standard Linux /dev/fb style framebuffer device. The framebuffer has
+    support for 8, 16 & 32 bpp packed pixel formats with alpha channel. In 16bpp
+    mode, there is a choice of a three color depths (12, 15 or 16 bits), but no
+    local alpha. The colorspace is selectable between rgb & yuv.
+    Depending on the TV standard configured in the ivtv module at load time,
+    the initial resolution is either 640x400 (NTSC) or 640x480 (PAL) at 8bpp.
+    Video timings are locked to ensure a vertical refresh rate of 50Hz (PAL)
+    or 59.94 (NTSC)

- * generic helper functions for video4linux capture buffers, to handle

- * Right now, bttv, saa7134, saa7146 and cx88 use it.
- *
- * The functions expect the hardware being able to scatter gatter
- * (i.e. the buffers are not linear in physical memory, but fragmented
- * into PAGE_SIZE chunks).  They also assume the driver does not need
- * to touch the video data.
- *
- * device specific map/unmap/sync stuff now are mapped as operations
- * to allow its usage by USB and virtual devices.

+ * - MMC depends on a different chipselect management policy than the
+ *   SPI interface currently supports for shared bus segments:  it needs
+ *   to issue multiple spi_message requests with the chipselect active,
+ *   using the results of one message to decide the next one to issue.
+ *
+ *   Pending updates to the programming interface, this driver expects
+ *   that it not share the bus with other drivers (precluding conflicts).
+ *
+ * - We tell the controller to keep the chipselect active from the
+ *   beginning of an mmc_host_ops.request until the end.  So beware
+ *   of SPI controller drivers that mis-handle the cs_change flag!
+ *
+ *   However, many cards seem OK with chipselect flapping up/down

- *	Digi RightSwitch SE-X loadable device driver for Linux
- *
- *	The RightSwitch is a 4 (EISA) or 6 (PCI) port etherswitch and
- *	a NIC on an internal board.
- *
- *	Author: Rick Richardson, rick@remotepoint.com
- *	Derived from the SVR4.2 (UnixWare) driver for the same card.
- *
- *	Copyright 1995-1996 Digi International Inc.
- *
- *	This software may be used and distributed according to the terms
- *	of the GNU General Public License, incorporated herein by reference.
- *
- *	For information on purchasing a RightSwitch SE-4 or SE-6
- *	board, please contact Digi's sales department at 1-612-912-3444
- *	or 1-800-DIGIBRD.  Outside the U.S., please check our Web page
- *	at http://www.dgii.com for sales offices worldwide.
- *
- *	OPERATION:
- *	When compiled as a loadable module, this driver can operate
- *	the board as either a 4/6 port switch with a 5th or 7th port
- *	that is a conventional NIC interface as far as the host is
- *	concerned, OR as 4/6 independent NICs.  To select multi-NIC
- *	mode, add "nicmode=1" on the insmod load line for the driver.
- *
- *	This driver uses the "dev" common ethernet device structure
- *	and a private "priv" (dev->priv) structure that contains
- *	mostly DGRS-specific information and statistics.  To keep
- *	the code for both the switch mode and the multi-NIC mode
- *	as similar as possible, I have introduced the concept of
- *	"dev0"/"priv0" and "devN"/"privN"  pointer pairs in subroutines
- *	where needed.  The first pair of pointers points to the
- *	"dev" and "priv" structures of the zeroth (0th) device
- *	interface associated with a board.  The second pair of
- *	pointers points to the current (Nth) device interface
- *	for the board: the one for which we are processing data.
- *
- *	In switch mode, the pairs of pointers are always the same,
- *	that is, dev0 == devN and priv0 == privN.  This is just
- *	like previous releases of this driver which did not support
- *	NIC mode.
- *
- *	In multi-NIC mode, the pairs of pointers may be different.
- *	We use the devN and privN pointers to reference just the
- *	name, port number, and statistics for the current interface.
- *	We use the dev0 and priv0 pointers to access the variables
- *	that control access to the board, such as board address
- *	and simulated 82596 variables.  This is because there is
- *	only one "fake" 82596 that serves as the interface to
- *	the board.  We do not want to try to keep the variables
- *	associated with this 82596 in sync across all devices.
- *
- *	This scheme works well.  As you will see, except for
- *	initialization, there is very little difference between
- *	the two modes as far as this driver is concerned.  On the
- *	receive side in NIC mode, the interrupt *always* comes in on
- *	the 0th interface (dev0/priv0).  We then figure out which
- *	real 82596 port it came in on from looking at the "chan"
- *	member that the board firmware adds at the end of each
- *	RBD (a.k.a. TBD). We get the channel number like this:
- *		int chan = ((I596_RBD *) S2H(cbp->xmit.tbdp))->chan;
- *
- *	On the transmit side in multi-NIC mode, we specify the
- *	output 82596 port by setting the new "dstchan" structure
- *	member that is at the end of the RFD, like this:
- *		priv0->rfdp->dstchan = privN->chan;
- *
- *	TODO:
- *	- Multi-NIC mode is not yet supported when the driver is linked
- *	  into the kernel.
- *	- Better handling of multicast addresses.
- *
- *	Fixes:
- *	Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 11/01/2001
- *	- fix dgrs_found_device wrt checking kmalloc return and
- *	rollbacking the partial steps of the whole process when
- *	one of the devices can't be allocated. Fix SET_MODULE_OWNER
- *	on the loop to use devN instead of repeated calls to dev.
- *
- *	davej <davej@suse.de> - 9/2/2001
- *	- Enable PCI device before reading ioaddr/irq

+/*
+ * Following is my most current (2007-07-17) understanding of how the Kingsun
+ * KS-959 dongle is supposed to work. This information was deduced by
+ * reverse-engineering and examining the USB traffic captured with USBSnoopy
+ * from the WinXP driver. Feel free to update here as more of the dongle is
+ * known.
+ *
+ * My most sincere thanks must go to Domen Puncer <domen@coderock.org> for
+ * invaluable help in cracking the obfuscation and padding required for this
+ * dongle.
+ *
+ * General: This dongle exposes one interface with one interrupt IN endpoint.
+ * However, the interrupt endpoint is NOT used at all for this dongle. Instead,
+ * this dongle uses control transfers for everything, including sending and
+ * receiving the IrDA frame data. Apparently the interrupt endpoint is just a
+ * dummy to ensure the dongle has a valid interface to present to the PC.And I
+ * thought the DonShine dongle was weird... In addition, this dongle uses
+ * obfuscation (?!?!), applied at the USB level, to hide the traffic, both sent
+ * and received, from the dongle. I call it obfuscation because the XOR keying
+ * and padding required to produce an USB traffic acceptable for the dongle can
+ * not be explained by any other technical requirement.
+ *
+ * Transmission: To transmit an IrDA frame, the driver must prepare a control
+ * URB with the following as a setup packet:
+ *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
+ *    bRequest        0x09
+ *    wValue          <length of valid data before padding, little endian>
+ *    wIndex          0x0000
+ *    wLength         <length of padded data>
+ * The payload packet must be manually wrapped and escaped (as in stir4200.c),
+ * then padded and obfuscated before being sent. Both padding and obfuscation
+ * are implemented in the procedure obfuscate_tx_buffer(). Suffice to say, the
+ * designer/programmer of the dongle used his name as a source for the
+ * obfuscation. WTF?!
+ * Apparently the dongle cannot handle payloads larger than 256 bytes. The
+ * driver has to perform fragmentation in order to send anything larger than
+ * this limit.
+ *
+ * Reception: To receive data, the driver must poll the dongle regularly (like
+ * kingsun-sir.c) with control URBs and the following as a setup packet:
+ *    bRequestType    USB_DIR_IN | USB_TYPE_CLASS | USB_RECIP_INTERFACE
+ *    bRequest        0x01
+ *    wValue          0x0200
+ *    wIndex          0x0000
+ *    wLength         0x0800 (size of available buffer)
+ * If there is data to be read, it will be returned as the response payload.
+ * This data is (apparently) not padded, but it is obfuscated. To de-obfuscate
+ * it, the driver must XOR every byte, in sequence, with a value that starts at
+ * 1 and is incremented with each byte processed, and then with 0x55. The value
+ * incremented with each byte processed overflows as an unsigned char. The
+ * resulting bytes form a wrapped SIR frame that is unwrapped and unescaped
+ * as in stir4200.c The incremented value is NOT reset with each frame, but is
+ * kept across the entire session with the dongle. Also, the dongle inserts an
+ * extra garbage byte with value 0x95 (after decoding) every 0xff bytes, which
+ * must be skipped.
+ *
+ * Speed change: To change the speed of the dongle, the driver prepares a
+ * control URB with the following as a setup packet:
+ *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
+ *    bRequest        0x09
+ *    wValue          0x0200
+ *    wIndex          0x0001
+ *    wLength         0x0008 (length of the payload)
+ * The payload is a 8-byte record, apparently identical to the one used in
+ * drivers/usb/serial/cypress_m8.c to change speed:
+ *     __u32 baudSpeed;
+ *    unsigned int dataBits : 2;    // 0 - 5 bits 3 - 8 bits
+ *    unsigned int : 1;
+ *    unsigned int stopBits : 1;
+ *    unsigned int parityEnable : 1;
+ *    unsigned int parityType : 1;
+ *    unsigned int : 1;
+ *    unsigned int reset : 1;
+ *    unsigned char reserved[3];    // set to 0
+ *
+ * For now only SIR speeds have been observed with this dongle. Therefore,
+ * nothing is known on what changes (if any) must be done to frame wrapping /
+ * unwrapping for higher than SIR speeds. This driver assumes no change is
+ * necessary and announces support for all the way to 57600 bps. Although the
+ * package announces support for up to 4MBps, tests with a Sony Ericcson K300
+ * phone show corruption when receiving large frames at 115200 bps, the highest
+ * speed announced by the phone. However, transmission at 115200 bps is OK. Go
+ * figure. Since I don't know whether the phone or the dongle is at fault, max
+ * announced speed is 57600 bps until someone produces a device that can run
+ * at higher speeds with this dongle.

+/*
+ * Following is my most current (2007-07-26) understanding of how the Kingsun
+ * 07D0:4100 dongle (sometimes known as the MA-660) is supposed to work. This
+ * information was deduced by examining the USB traffic captured with USBSnoopy
+ * from the WinXP driver. Feel free to update here as more of the dongle is
+ * known.
+ *
+ * General: This dongle exposes one interface with two interrupt endpoints, one
+ * IN and one OUT. In this regard, it is similar to what the Kingsun/Donshine
+ * dongle (07c0:4200) exposes. Traffic is raw and needs to be wrapped and
+ * unwrapped manually as in stir4200, kingsun-sir, and ks959-sir.
+ *
+ * Transmission: To transmit an IrDA frame, it is necessary to wrap it, then
+ * split it into multiple segments of up to 7 bytes each, and transmit each in
+ * sequence. It seems that sending a single big block (like kingsun-sir does)
+ * won't work with this dongle. Each segment needs to be prefixed with a value
+ * equal to (unsigned char)0xF8 + <number of bytes in segment>, inside a payload
+ * of exactly 8 bytes. For example, a segment of 1 byte gets prefixed by 0xF9,
+ * and one of 7 bytes gets prefixed by 0xFF. The bytes at the end of the
+ * payload, not considered by the prefix, are ignored (set to 0 by this
+ * implementation).
+ *
+ * Reception: To receive data, the driver must poll the dongle regularly (like
+ * kingsun-sir.c) with interrupt URBs. If data is available, it will be returned
+ * in payloads from 0 to 8 bytes long. When concatenated, these payloads form
+ * a raw IrDA stream that needs to be unwrapped as in stir4200 and kingsun-sir
+ *
+ * Speed change: To change the speed of the dongle, the driver prepares a
+ * control URB with the following as a setup packet:
+ *    bRequestType    USB_DIR_OUT | USB_TYPE_CLASS | USB_RECIP_INTERFACE
+ *    bRequest        0x09
+ *    wValue          0x0200
+ *    wIndex          0x0001
+ *    wLength         0x0008 (length of the payload)
+ * The payload is a 8-byte record, apparently identical to the one used in
+ * drivers/usb/serial/cypress_m8.c to change speed:
+ *     __u32 baudSpeed;
+ *    unsigned int dataBits : 2;    // 0 - 5 bits 3 - 8 bits
+ *    unsigned int : 1;
+ *    unsigned int stopBits : 1;
+ *    unsigned int parityEnable : 1;
+ *    unsigned int parityType : 1;
+ *    unsigned int : 1;
+ *    unsigned int reset : 1;
+ *    unsigned char reserved[3];    // set to 0
+ *
+ * For now only SIR speeds have been observed with this dongle. Therefore,
+ * nothing is known on what changes (if any) must be done to frame wrapping /
+ * unwrapping for higher than SIR speeds. This driver assumes no change is
+ * necessary and announces support for all the way to 115200 bps.

+ * RX HW/SW interaction overview
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ * There are 2 types of RX communication channels betwean driver and NIC.
+ * 1) RX Free Fifo - RXF - holds descriptors of empty buffers to accept incoming
+ * traffic. This Fifo is filled by SW and is readen by HW. Each descriptor holds
+ * info about buffer's location, size and ID. An ID field is used to identify a
+ * buffer when it's returned with data via RXD Fifo (see below)
+ * 2) RX Data Fifo - RXD - holds descriptors of full buffers. This Fifo is
+ * filled by HW and is readen by SW. Each descriptor holds status and ID.
+ * HW pops descriptor from RXF Fifo, stores ID, fills buffer with incoming data,
+ * via dma moves it into host memory, builds new RXD descriptor with same ID,
+ * pushes it into RXD Fifo and raises interrupt to indicate new RX data.
+ *
+ * Current NIC configuration (registers + firmware) makes NIC use 2 RXF Fifos.
+ * One holds 1.5K packets and another - 26K packets. Depending on incoming
+ * packet size, HW desides on a RXF Fifo to pop buffer from. When packet is
+ * filled with data, HW builds new RXD descriptor for it and push it into single
+ * RXD Fifo.
+ *
+ * RX SW Data Structures
+ * ~~~~~~~~~~~~~~~~~~~~~
+ * skb db - used to keep track of all skbs owned by SW and their dma addresses.
+ * For RX case, ownership lasts from allocating new empty skb for RXF until
+ * accepting full skb from RXD and passing it to OS. Each RXF Fifo has its own
+ * skb db. Implemented as array with bitmask.
+ * fifo - keeps info about fifo's size and location, relevant HW registers,
+ * usage and skb db. Each RXD and RXF Fifo has its own fifo structure.
+ * Implemented as simple struct.
+ *
+ * RX SW Execution Flow
+ * ~~~~~~~~~~~~~~~~~~~~
+ * Upon initialization (ifconfig up) driver creates RX fifos and initializes
+ * relevant registers. At the end of init phase, driver enables interrupts.
+ * NIC sees that there is no RXF buffers and raises
+ * RD_INTR interrupt, isr fills skbs and Rx begins.
+ * Driver has two receive operation modes:
+ *    NAPI - interrupt-driven mixed with polling
+ *    interrupt-driven only
+ *
+ * Interrupt-driven only flow is following. When buffer is ready, HW raises
+ * interrupt and isr is called. isr collects all available packets
+ * (bdx_rx_receive), refills skbs (bdx_rx_alloc_skbs) and exit.
+
+ * Rx buffer allocation note
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~
+ * Driver cares to feed such amount of RxF descriptors that respective amount of
+ * RxD descriptors can not fill entire RxD fifo. The main reason is lack of
+ * overflow check in Bordeaux for RxD fifo free/used size.
+ * FIXME: this is NOT fully implemented, more work should be done
+ *

+ * txdb - used to keep track of all skbs owned by SW and their dma addresses.
+ * For TX case, ownership lasts from geting packet via hard_xmit and until HW
+ * acknowledges sent by TXF descriptors.
+ * Implemented as cyclic buffer.
+ * fifo - keeps info about fifo's size and location, relevant HW registers,
+ * usage and skb db. Each RXD and RXF Fifo has its own fifo structure.
+ * Implemented as simple struct.
+ *
+ * TX SW Execution Flow
+ * ~~~~~~~~~~~~~~~~~~~~
+ * OS calls driver's hard_xmit method with packet to sent.
+ * Driver creates DMA mappings, builds TXD descriptors and kicks HW
+ * by updating TXD WPTR.
+ * When packet is sent, HW write us TXF descriptor and SW frees original skb.
+ * To prevent TXD fifo overflow without reading HW registers every time,
+ * SW deploys "tx level" technique.
+ * Upon strart up, tx level is initialized to TXD fifo length.
+ * For every sent packet, SW gets its TXD descriptor sizei
+ * (from precalculated array) and substructs it from tx level.
+ * The size is also stored in txdb. When TXF ack arrives, SW fetch size of
+ * original TXD descriptor from txdb and adds it to tx level.
+ * When Tx level drops under some predefined treshhold, the driver
+ * stops the TX queue. When TX level rises above that level,
+ * the tx queue is enabled again.
+ *
+ * This technique avoids eccessive reading of RPTR and WPTR registers.
+ * As our benchmarks shows, it adds 1.5 Gbit/sec to NIS's throuput.

+	  b43 is a driver for the Broadcom 43xx series wireless devices.
+
+	  Check "lspci" for something like
+	  "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
+	  to determine whether you own such a device.
+
+	  This driver supports the new BCM43xx IEEE 802.11G devices, but not
+	  the old IEEE 802.11B devices. Old devices are supported by
+	  the b43legacy driver.
+	  Note that this has nothing to do with the standard that your AccessPoint
+	  supports (A, B, G or a combination).
+	  IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
+
+	  It is safe to include both b43 and b43legacy as the underlying glue
+	  layer will automatically load the correct version for your device.
+
+	  This driver uses V4 firmware, which must be installed separately using
+	  b43-fwcutter.
+
+	  This driver can be built as a module (recommended) that will be called "b43".
+	  If unsure, say M.
+
+# Auto-select SSB PCI-HOST support, if possible
+config B43_PCI_AUTOSELECT
+	bool
+	depends on B43 && SSB_PCIHOST_POSSIBLE
+	select SSB_PCIHOST
+	default y

+	depends on B43 && SSB_DRIVER_PCICORE_POSSIBLE
+	select SSB_DRIVER_PCICORE

+	---help---
+	  Broadcom 43xx PCMCIA device support.
+
+	  Support for 16bit PCMCIA devices.
+	  Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
+	  devices, but 32bit CardBUS devices. CardBUS devices are supported
+	  out of the box by b43.
+
+	  With this config option you can drive b43 cards in
+	  CompactFlash formfactor in a PCMCIA adaptor.
+	  CF b43 cards can sometimes be found in handheld PCs.
+
+	  It's safe to select Y here, even if you don't have a B43 PCMCIA device.
+
+	  If unsure, say N.
+
+# LED support
+config B43_LEDS
+	bool
+	depends on B43 && MAC80211_LEDS
+	default y
+
+# RFKILL support
+config B43_RFKILL

+	default y
+
+config B43_DEBUG
+	bool "Broadcom 43xx debugging"
+	depends on B43
+	---help---
+	  Broadcom 43xx debugging messages.
+
+	  Say Y, if you want to find out why the driver does not
+	  work for you.
+

+	depends on B43
+config B43_PIO
+	bool
+	depends on B43

+
+config B43_DMA_AND_PIO_MODE
+	bool "DMA + PIO"
+	select B43_DMA
+	select B43_PIO
+	---help---
+	  Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
+	  data transfer modes.
+	  The actually used mode is selectable through the module
+	  parameter "pio". If the module parameter is pio=0, DMA is used.
+	  Otherwise PIO is used. DMA is default.
+
+	  If unsure, choose this option.
+
+config B43_DMA_MODE
+	bool "DMA (Direct Memory Access) only"
+	select B43_DMA
+	---help---
+	  Only include Direct Memory Access (DMA).
+	  This reduces the size of the driver module, by omitting the PIO code.
+
+config B43_PIO_MODE
+	bool "PIO (Programmed I/O) only"
+	select B43_PIO
+	---help---
+	  Only include Programmed I/O (PIO).
+	  This reduces the size of the driver module, by omitting the DMA code.
+	  Please note that PIO transfers are slow (compared to DMA).
+
+	  Also note that not all devices of the 43xx series support PIO.
+	  The 4306 (Apple Airport Extreme and others) supports PIO, while
+	  the 4318 is known to _not_ support PIO.
+
+	  Only use PIO, if DMA does not work for you.

+	  b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and

+
+	  It is safe to include both b43 and b43legacy as the underlying glue
+	  layer will automatically load the correct version for your device.
+
+	  This driver uses V3 firmware, which must be installed separately using
+	  b43-fwcutter.
+
+	  This driver can be built as a module (recommended) that will be
+	  called "b43legacy". If unsure, say M.

+ * A single _ prefix before a an access function means that no state
+ * check or debug information is printed when that function is called.
+ *
+ * A double __ prefix before an access function means that state is checked

+ *
+ * The non-prefixed name is the #define that maps the caller into a

+ *
+ * If you wish to call the function without any debug or state checking,
+ * you should use the single _ prefix version (as is used by dependent IO
+ * routines, for example _iwl_read_restricted calls the non-check version of
+ * _iwl_read32.)
+ *
+ * These declarations are *extremely* useful in quickly isolating code deltas

+/**
+ * BSM (Bootstrap State Machine)
+ *
+ * The Bootstrap State Machine (BSM) stores a short bootstrap uCode program
+ * in special SRAM that does not power down when the embedded control
+ * processor is sleeping (e.g. for periodic power-saving shutdowns of radio).
+ *
+ * When powering back up after sleeps (or during initial uCode load), the BSM
+ * internally loads the short bootstrap program from the special SRAM into the
+ * embedded processor's instruction SRAM, and starts the processor so it runs
+ * the bootstrap program.
+ *
+ * This bootstrap program loads (via PCI busmaster DMA) instructions and data
+ * images for a uCode program from host DRAM locations.  The host driver
+ * indicates DRAM locations and sizes for instruction and data images via the
+ * four BSM_DRAM_* registers.  Once the bootstrap program loads the new program,
+ * the new program starts automatically.
+ *
+ * The uCode used for open-source drivers includes two programs:
+ *
+ * 1)  Initialization -- performs hardware calibration and sets up some
+ *     internal data, then notifies host via "initialize alive" notification
+ *     (struct iwl_init_alive_resp) that it has completed all of its work.
+ *     After signal from host, it then loads and starts the runtime program.
+ *     The initialization program must be used when initially setting up the
+ *     NIC after loading the driver.
+ *
+ * 2)  Runtime/Protocol -- performs all normal runtime operations.  This
+ *     notifies host via "alive" notification (struct iwl_alive_resp) that it
+ *     is ready to be used.
+ *
+ * When initializing the NIC, the host driver does the following procedure:
+ *
+ * 1)  Load bootstrap program (instructions only, no data image for bootstrap)
+ *     into bootstrap memory.  Use dword writes starting at BSM_SRAM_LOWER_BOUND
+ *
+ * 2)  Point (via BSM_DRAM_*) to the "initialize" uCode data and instruction
+ *     images in host DRAM.
+ *
+ * 3)  Set up BSM to copy from BSM SRAM into uCode instruction SRAM when asked:
+ *     BSM_WR_MEM_SRC_REG = 0
+ *     BSM_WR_MEM_DST_REG = RTC_INST_LOWER_BOUND
+ *     BSM_WR_MEM_DWCOUNT_REG = # dwords in bootstrap instruction image
+ *
+ * 4)  Load bootstrap into instruction SRAM:
+ *     BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START
+ *
+ * 5)  Wait for load completion:
+ *     Poll BSM_WR_CTRL_REG for BSM_WR_CTRL_REG_BIT_START = 0
+ *
+ * 6)  Enable future boot loads whenever NIC's power management triggers it:
+ *     BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START_EN
+ *
+ * 7)  Start the NIC by removing all reset bits:
+ *     CSR_RESET = 0
+ *
+ *     The bootstrap uCode (already in instruction SRAM) loads initialization
+ *     uCode.  Initialization uCode performs data initialization, sends
+ *     "initialize alive" notification to host, and waits for a signal from
+ *     host to load runtime code.
+ *
+ * 4)  Point (via BSM_DRAM_*) to the "runtime" uCode data and instruction
+ *     images in host DRAM.  The last register loaded must be the instruction
+ *     bytecount register ("1" in MSbit tells initialization uCode to load
+ *     the runtime uCode):
+ *     BSM_DRAM_INST_BYTECOUNT_REG = bytecount | BSM_DRAM_INST_LOAD
+ *
+ * 5)  Wait for "alive" notification, then issue normal runtime commands.
+ *
+ * Data caching during power-downs:
+ *
+ * Just before the embedded controller powers down (e.g for automatic
+ * power-saving modes, or for RFKILL), uCode stores (via PCI busmaster DMA)
+ * a current snapshot of the embedded processor's data SRAM into host DRAM.
+ * This caches the data while the embedded processor's memory is powered down.
+ * Location and size are controlled by BSM_DRAM_DATA_* registers.
+ *
+ * NOTE:  Instruction SRAM does not need to be saved, since that doesn't
+ *        change during operation; the original image (from uCode distribution
+ *        file) can be used for reload.
+ *
+ * When powering back up, the BSM loads the bootstrap program.  Bootstrap looks
+ * at the BSM_DRAM_* registers, which now point to the runtime instruction
+ * image and the cached (modified) runtime data (*not* the initialization
+ * uCode).  Bootstrap reloads these runtime images into SRAM, and restarts the
+ * uCode from where it left off before the power-down.
+ *
+ * NOTE:  Initialization uCode does *not* run as part of the save/restore
+ *        procedure.
+ *
+ * This save/restore method is mostly for autonomous power management during
+ * normal operation (result of POWER_TABLE_CMD).  Platform suspend/resume and
+ * RFKILL should use complete restarts (with total re-initialization) of uCode,
+ * allowing total shutdown (including BSM memory).
+ *
+ * Note that, during normal operation, the host DRAM that held the initial
+ * startup data for the runtime code is now being used as a backup data cache
+ * for modified data!  If you need to completely re-initialize the NIC, make
+ * sure that you use the runtime data image from the uCode distribution file,
+ * not the modified/saved runtime data.  You may want to store a separate
+ * "clean" runtime data image in DRAM to avoid disk reads of distribution file.

+/*
+ * Rx theory of operation
+ *
+ * The host allocates 32 DMA target addresses and passes the host address
+ * to the firmware at register IWL_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
+ * 0 to 31
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer it will advance the READ index
+ * and fire the RX interrupt.  The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
+ *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ *   to replensish the iwl->rxq->rx_free.
+ * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
+ *   iwl->rxq is replenished and the READ INDEX is updated (updating the
+ *   'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ *   detached from the iwl->rxq.  The driver 'processed' index is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ *   INDEX is not incremented and iwl->status(RX_STALLED) is set.  If there
+ *   were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * iwl_rx_queue_alloc()       Allocates rx_free
+ * iwl_rx_replenish()         Replenishes rx_free list from rx_used, and calls
+ *                            iwl_rx_queue_restock
+ * iwl_rx_queue_restock()     Moves available buffers from rx_free into Rx
+ *                            queue, updates firmware pointers, and updates
+ *                            the WRITE index.  If insufficient rx_free buffers
+ *                            are available, schedules iwl_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - iwl_rx()             Detach iwl_rx_mem_buffers from pool up to the
+ *                            READ INDEX, detaching the SKB from the pool.
+ *                            Moves the packet buffer from queue to rx_used.
+ *                            Calls iwl_rx_queue_restock to refill any empty

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwl_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel.  We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware.  This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel.  There is no corresponding channel information for that
+ * entry.

+ * notifies host via "initialize alive" that it is complete.
+ *
+ * The host then replaces the BSM_DRAM_* pointer values to point to the
+ * normal runtime uCode instructions and a backup uCode data cache buffer
+ * (filled initially with starting data values for the on-board processor),
+ * then triggers the "initialize" uCode to load and launch the runtime uCode,
+ * which begins normal operation.
+ *
+ * When doing a power-save shutdown, runtime uCode saves data SRAM into
+ * the backup data cache in DRAM before SRAM is powered down.
+ *

+/************************** RX-FUNCTIONS ****************************/
+/*
+ * Rx theory of operation
+ *
+ * The host allocates 32 DMA target addresses and passes the host address
+ * to the firmware at register IWL_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
+ * 0 to 31
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer it will advance the READ index
+ * and fire the RX interrupt.  The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
+ *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ *   to replensish the iwl->rxq->rx_free.
+ * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
+ *   iwl->rxq is replenished and the READ INDEX is updated (updating the
+ *   'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ *   detached from the iwl->rxq.  The driver 'processed' index is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ *   INDEX is not incremented and iwl->status(RX_STALLED) is set.  If there
+ *   were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * iwl_rx_queue_alloc()       Allocates rx_free
+ * iwl_rx_replenish()         Replenishes rx_free list from rx_used, and calls
+ *                            iwl_rx_queue_restock
+ * iwl_rx_queue_restock()     Moves available buffers from rx_free into Rx
+ *                            queue, updates firmware pointers, and updates
+ *                            the WRITE index.  If insufficient rx_free buffers
+ *                            are available, schedules iwl_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - iwl_rx()             Detach iwl_rx_mem_buffers from pool up to the
+ *                            READ INDEX, detaching the SKB from the pool.
+ *                            Moves the packet buffer from queue to rx_used.
+ *                            Calls iwl_rx_queue_restock to refill any empty

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwl_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel.  We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware.  This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel.  There is no corresponding channel information for that
+ * entry.

+ * (filled initially with starting data values for the on-board processor),

+2.1.29 - Fix a deadlock at mount time.
+
+	- During mount the VFS holds s_umount lock on the superblock.  So when
+	  we try to empty the journal $LogFile contents by calling
+	  ntfs_attr_set() when the machine does not have much memory and the
+	  journal is large ntfs_attr_set() results in the VM trying to balance
+	  dirty pages which in turn tries to that the s_umount lock and thus we
+	  get a deadlock.  The solution is to not use ntfs_attr_set() and
+	  instead do the zeroing by hand at the block level rather than page
+	  cache level.
+	- Fix sparse warnings.
+
 2.1.28 - Fix a deadlock.
 
 	- Fix deadlock in fs/ntfs/inode.c::ntfs_put_inode().  Thanks to Sergey

- * read_barrier_depends - Flush all pending reads that subsequents reads

- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier.  All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads.  This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies.  See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- *	CPU 0				CPU 1
- *
- *	b = 2;
- *	memory_barrier();
- *	p = &b;				q = p;
- *					read_barrier_depends();
- *					d = *q;
- * </programlisting>
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends().  However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- *	CPU 0				CPU 1
- *
- *	a = 2;
- *	memory_barrier();
- *	b = 3;				y = b;
- *					read_barrier_depends();
- *					x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b".  Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
- * in cases like this where there are no data dependencies.

+ * read_barrier_depends - Flush all pending reads that subsequents reads
+ * depend on.
+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier.  All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads.  This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies.  See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	b = 2;
+ *	memory_barrier();
+ *	p = &b;				q = p;
+ *					read_barrier_depends();
+ *					d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends().  However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	a = 2;
+ *	memory_barrier();
+ *	b = 3;				y = b;
+ *					read_barrier_depends();
+ *					x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b".  Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
+ * in cases like this where there are no data dependencies.

+ * struct usb_request - describes one i/o request
+ * @buf: Buffer used for data.  Always provide this; some controllers
+ *	only use PIO, or don't use DMA for some endpoints.
+ * @dma: DMA address corresponding to 'buf'.  If you don't set this
+ *	field, and the usb controller needs one, it is responsible
+ *	for mapping and unmapping the buffer.
+ * @length: Length of that data
+ * @no_interrupt: If true, hints that no completion irq is needed.
+ *	Helpful sometimes with deep request queues that are handled
+ *	directly by DMA controllers.
+ * @zero: If true, when writing data, makes the last packet be "short"
+ *     by adding a zero length packet as needed;
+ * @short_not_ok: When reading data, makes short packets be
+ *     treated as errors (queue stops advancing till cleanup).
+ * @complete: Function called when request completes, so this request and
+ *	its buffer may be re-used.
+ *	Reads terminate with a short packet, or when the buffer fills,
+ *	whichever comes first.  When writes terminate, some data bytes
+ *	will usually still be in flight (often in a hardware fifo).
+ *	Errors (for reads or writes) stop the queue from advancing
+ *	until the completion function returns, so that any transfers
+ *	invalidated by the error may first be dequeued.
+ * @context: For use by the completion callback
+ * @list: For use by the gadget driver.
+ * @status: Reports completion code, zero or a negative errno.
+ *	Normally, faults block the transfer queue from advancing until
+ *	the completion callback returns.
+ *	Code "-ESHUTDOWN" indicates completion caused by device disconnect,
+ *	or when the driver disabled the endpoint.
+ * @actual: Reports bytes transferred to/from the buffer.  For reads (OUT
+ *	transfers) this may be less than the requested length.  If the
+ *	short_not_ok flag is set, short reads are treated as errors
+ *	even when status otherwise indicates successful completion.
+ *	Note that for writes (IN transfers) some data bytes may still
+ *	reside in a device-side FIFO when the request is reported as
+ *	complete.
+ *
+ * These are allocated/freed through the endpoint they're used with.  The
+ * hardware's driver can add extra per-request data to the memory it returns,
+ * which often avoids separate memory allocations (potential failures),
+ * later when the request is queued.
+ *
+ * Request flags affect request handling, such as whether a zero length
+ * packet is written (the "zero" flag), whether a short read should be
+ * treated as an error (blocking request queue advance, the "short_not_ok"
+ * flag), or hinting that an interrupt is not required (the "no_interrupt"
+ * flag, for use with deep request queues).
+ *
+ * Bulk endpoints can use any size buffers, and can also be used for interrupt
+ * transfers. interrupt-only endpoints can be much less functional.

+ *	At that point, ep0 is fully initialized, and ep_list holds
+ *	the currently-available endpoints.
+ *	Called in a context that permits sleeping.
+ * @setup: Invoked for ep0 control requests that aren't handled by

+ *	the gadget driver, including descriptor and configuration
+ *	management.  The 16 bit members of the setup data are in
+ *	USB byte order. Called in_interrupt; this may not sleep.  Driver
+ *	queues a response to ep0, or returns negative to stall.
+ * @disconnect: Invoked after all transfers have been stopped,
+ *	when the host is disconnected.  May be called in_interrupt; this
+ *	may not sleep.  Some devices can't detect disconnect, so this might
+ *	not be called except as part of controller shutdown.
+ * @unbind: Invoked when the driver is unbound from a gadget,
+ *	usually from rmmod (after a disconnect is reported).
+ *	Called in a context that permits sleeping.
+ * @suspend: Invoked on USB suspend.  May be called in_interrupt.
+ * @resume: Invoked on USB resume.  May be called in_interrupt.
+ * @driver: Driver model state for this driver.
+ *
+ * Devices are disabled till a gadget driver successfully bind()s, which
+ * means the driver will handle setup() requests needed to enumerate (and
+ * meet "chapter 9" requirements) then do some useful work.
+ *
+ * If gadget->is_otg is true, the gadget driver must provide an OTG
+ * descriptor during enumeration, or else fail the bind() call.  In such
+ * cases, no USB traffic may flow until both bind() returns without
+ * having called usb_gadget_disconnect(), and the USB host stack has
+ * initialized.
+ *
+ * Drivers use hardware-specific knowledge to configure the usb hardware.
+ * endpoint addressing is only one of several hardware characteristics that
+ * are in descriptors the ep0 implementation returns from setup() calls.
+ *
+ * Except for ep0 implementation, most driver code shouldn't need change to
+ * run on top of different usb controllers.  It'll use endpoints set up by
+ * that ep0 implementation.
+ *
+ * The usb controller driver handles a few standard usb requests.  Those
+ * include set_address, and feature flags for devices, interfaces, and
+ * endpoints (the get_status, set_feature, and clear_feature requests).
+ *
+ * Accordingly, the driver's setup() callback must always implement all
+ * get_descriptor requests, returning at least a device descriptor and
+ * a configuration descriptor.  Drivers must make sure the endpoint
+ * descriptors match any hardware constraints. Some hardware also constrains
+ * other descriptors. (The pxa250 allows only configurations 1, 2, or 3).
+ *
+ * The driver's setup() callback must also implement set_configuration,
+ * and should also implement set_interface, get_configuration, and
+ * get_interface.  Setting a configuration (or interface) is where
+ * endpoints should be activated or (config 0) shut down.
+ *
+ * (Note that only the default control endpoint is supported.  Neither
+ * hosts nor devices generally support control traffic except to ep0.)
+ *
+ * Most devices will ignore USB suspend/resume operations, and so will
+ * not provide those callbacks.  However, some may need to change modes
+ * when the host is not longer directing those activities.  For example,
+ * local controls (buttons, dials, etc) may need to be re-enabled since
+ * the (remote) host can't do that any longer; or an error state might
+ * be cleared, to make the device behave identically whether or not
+ * power is maintained.

- * struct usb_request - describes one i/o request
- * @buf: Buffer used for data.  Always provide this; some controllers
- * 	only use PIO, or don't use DMA for some endpoints.
- * @dma: DMA address corresponding to 'buf'.  If you don't set this
- * 	field, and the usb controller needs one, it is responsible
- * 	for mapping and unmapping the buffer.
- * @length: Length of that data
- * @no_interrupt: If true, hints that no completion irq is needed.
- *	Helpful sometimes with deep request queues that are handled
- *	directly by DMA controllers.
- * @zero: If true, when writing data, makes the last packet be "short"
- *     by adding a zero length packet as needed;
- * @short_not_ok: When reading data, makes short packets be
- *     treated as errors (queue stops advancing till cleanup).
- * @complete: Function called when request completes, so this request and
- *	its buffer may be re-used.
- *	Reads terminate with a short packet, or when the buffer fills,
- *	whichever comes first.  When writes terminate, some data bytes
- *	will usually still be in flight (often in a hardware fifo).
- *	Errors (for reads or writes) stop the queue from advancing
- *	until the completion function returns, so that any transfers
- *	invalidated by the error may first be dequeued.
- * @context: For use by the completion callback
- * @list: For use by the gadget driver.
- * @status: Reports completion code, zero or a negative errno.
- * 	Normally, faults block the transfer queue from advancing until
- * 	the completion callback returns.
- * 	Code "-ESHUTDOWN" indicates completion caused by device disconnect,
- * 	or when the driver disabled the endpoint.
- * @actual: Reports bytes transferred to/from the buffer.  For reads (OUT
- * 	transfers) this may be less than the requested length.  If the
- * 	short_not_ok flag is set, short reads are treated as errors
- * 	even when status otherwise indicates successful completion.
- * 	Note that for writes (IN transfers) some data bytes may still
- * 	reside in a device-side FIFO when the request is reported as
- *	complete.
- *
- * These are allocated/freed through the endpoint they're used with.  The
- * hardware's driver can add extra per-request data to the memory it returns,
- * which often avoids separate memory allocations (potential failures),
- * later when the request is queued.
- *
- * Request flags affect request handling, such as whether a zero length
- * packet is written (the "zero" flag), whether a short read should be
- * treated as an error (blocking request queue advance, the "short_not_ok"
- * flag), or hinting that an interrupt is not required (the "no_interrupt"
- * flag, for use with deep request queues).
- *
- * Bulk endpoints can use any size buffers, and can also be used for interrupt
- * transfers. interrupt-only endpoints can be much less functional.

- * This tells the device controller to perform the specified request through

- * request queued; they complete in FIFO order.  Once a gadget driver
- * submits a request, that request may not be examined or modified until it
- * is given back to that driver through the completion callback.
- *
- * Each request is turned into one or more packets.  The controller driver
- * never merges adjacent requests into the same packet.  OUT transfers
- * will sometimes use data that's already buffered in the hardware.
- * Drivers can rely on the fact that the first byte of the request's buffer
- * always corresponds to the first byte of some USB packet, for both

- *
- * Bulk endpoints can queue any amount of data; the transfer is packetized
- * automatically.  The last packet will be short if the request doesn't fill it
- * out completely.  Zero length packets (ZLPs) should be avoided in portable
- * protocols since not all usb hardware can successfully handle zero length
- * packets.  (ZLPs may be explicitly written, and may be implicitly written if
- * the request 'zero' flag is set.)  Bulk endpoints may also be used
- * for interrupt transfers; but the reverse is not true, and some endpoints
- * won't support every interrupt transfer.  (Such as 768 byte packets.)
- *
- * Interrupt-only endpoints are less functional than bulk endpoints, for
- * example by not supporting queueing or not handling buffers that are
- * larger than the endpoint's maxpacket size.  They may also treat data
- * toggle differently.
- *
- * Control endpoints ... after getting a setup() callback, the driver queues
- * one response (even if it would be zero length).  That enables the
- * status ack, after transfering data as specified in the response.  Setup
- * functions may return negative error codes to generate protocol stalls.
- * (Note that some USB device controllers disallow protocol stall responses
- * in some cases.)  When control responses are deferred (the response is
- * written after the setup callback returns), then usb_ep_set_halt() may be
- * used on ep0 to trigger protocol stalls.
- *
- * For periodic endpoints, like interrupt or isochronous ones, the usb host
- * arranges to poll once per interval, and the gadget driver usually will

- * meet "chapter 9" requirements) then do some useful work.
- *
- * If gadget->is_otg is true, the gadget driver must provide an OTG
- * descriptor during enumeration, or else fail the bind() call.  In such
- * cases, no USB traffic may flow until both bind() returns without
- * having called usb_gadget_disconnect(), and the USB host stack has
- * initialized.
- *
- * Drivers use hardware-specific knowledge to configure the usb hardware.
- * endpoint addressing is only one of several hardware characteristics that
- * are in descriptors the ep0 implementation returns from setup() calls.
- *
- * Except for ep0 implementation, most driver code shouldn't need change to
- * run on top of different usb controllers.  It'll use endpoints set up by
- * that ep0 implementation.
- *
- * The usb controller driver handles a few standard usb requests.  Those
- * include set_address, and feature flags for devices, interfaces, and
- * endpoints (the get_status, set_feature, and clear_feature requests).
- *
- * Accordingly, the driver's setup() callback must always implement all
- * get_descriptor requests, returning at least a device descriptor and
- * a configuration descriptor.  Drivers must make sure the endpoint
- * descriptors match any hardware constraints. Some hardware also constrains
- * other descriptors. (The pxa250 allows only configurations 1, 2, or 3).
- *
- * The driver's setup() callback must also implement set_configuration,

- * endpoints should be activated or (config 0) shut down.
- *
- * (Note that only the default control endpoint is supported.  Neither

+ *
+ * This structure contains various callbacks that the driver may
+ * handle or, in some cases, must handle, for example to configure
+ * the hardware to a new channel or to transmit a frame.
+ *
+ * @tx: Handler that 802.11 module calls for each transmitted frame.
+ *	skb contains the buffer starting from the IEEE 802.11 header.
+ *	The low-level driver should send the frame out based on
+ *	configuration in the TX control data. Must be implemented and
+ *	atomic.
+ *
+ * @start: Called before the first netdevice attached to the hardware
+ *	is enabled. This should turn on the hardware and must turn on
+ *	frame reception (for possibly enabled monitor interfaces.)
+ *	Returns negative error codes, these may be seen in userspace,
+ *	or zero.
+ *	When the device is started it should not have a MAC address
+ *	to avoid acknowledging frames before a non-monitor device
+ *	is added.
+ *	Must be implemented.
+ *
+ * @stop: Called after last netdevice attached to the hardware
+ *	is disabled. This should turn off the hardware (at least
+ *	it must turn off frame reception.)
+ *	May be called right after add_interface if that rejects
+ *	an interface.
+ *	Must be implemented.
+ *
+ * @add_interface: Called when a netdevice attached to the hardware is
+ *	enabled. Because it is not called for monitor mode devices, @open
+ *	and @stop must be implemented.
+ *	The driver should perform any initialization it needs before
+ *	the device can be enabled. The initial configuration for the
+ *	interface is given in the conf parameter.
+ *	The callback may refuse to add an interface by returning a
+ *	negative error code (which will be seen in userspace.)
+ *	Must be implemented.
+ *
+ * @remove_interface: Notifies a driver that an interface is going down.
+ *	The @stop callback is called after this if it is the last interface
+ *	and no monitor interfaces are present.
+ *	When all interfaces are removed, the MAC address in the hardware
+ *	must be cleared so the device no longer acknowledges packets,
+ *	the mac_addr member of the conf structure is, however, set to the
+ *	MAC address of the device going away.
+ *	Hence, this callback must be implemented.
+ *
+ * @config: Handler for configuration requests. IEEE 802.11 code calls this
+ *	function to change hardware configuration, e.g., channel.
+ *
+ * @config_interface: Handler for configuration requests related to interfaces
+ *	(e.g. BSSID changes.)
+ *
+ * @configure_filter: Configure the device's RX filter.
+ *	See the section "Frame filtering" for more information.
+ *	This callback must be implemented and atomic.
+ *
+ * @set_tim: Set TIM bit. If the hardware/firmware takes care of beacon
+ *	generation (that is, %IEEE80211_HW_HOST_GEN_BEACON_TEMPLATE is set)
+ *	mac80211 calls this function when a TIM bit must be set or cleared
+ *	for a given AID. Must be atomic.
+ *
+ * @set_key: See the section "Hardware crypto acceleration"
+ *	This callback can sleep, and is only called between add_interface
+ *	and remove_interface calls, i.e. while the interface with the
+ *	given local_address is enabled.
+ *
+ * @set_ieee8021x: Enable/disable IEEE 802.1X. This item requests wlan card
+ *	to pass unencrypted EAPOL-Key frames even when encryption is
+ *	configured. If the wlan card does not require such a configuration,
+ *	this function pointer can be set to NULL.
+ *
+ * @set_port_auth: Set port authorization state (IEEE 802.1X PAE) to be
+ *	authorized (@authorized=1) or unauthorized (=0). This function can be
+ *	used if the wlan hardware or low-level driver implements PAE.
+ *	mac80211 will filter frames based on authorization state in any case,
+ *	so this function pointer can be NULL if low-level driver does not
+ *	require event notification about port state changes.
+ *
+ * @hw_scan: Ask the hardware to service the scan request, no need to start
+ *	the scan state machine in stack.
+ *
+ * @get_stats: return low-level statistics
+ *
+ * @set_privacy_invoked: For devices that generate their own beacons and probe
+ *	response or association responses this updates the state of privacy_invoked
+ *	returns 0 for success or an error number.
+ *
+ * @get_sequence_counter: For devices that have internal sequence counters this
+ *	callback allows mac80211 to access the current value of a counter.
+ *	This callback seems not well-defined, tell us if you need it.
+ *
+ * @set_rts_threshold: Configuration of RTS threshold (if device needs it)
+ *
+ * @set_frag_threshold: Configuration of fragmentation threshold. Assign this if
+ *	the device does fragmentation by itself; if this method is assigned then
+ *	the stack will not do fragmentation.
+ *
+ * @set_retry_limit: Configuration of retry limits (if device needs it)
+ *
+ * @sta_notify: Notifies low level driver about addition or removal
+ *	of assocaited station or AP.
+ *
+ * @erp_ie_changed: Handle ERP IE change notifications. Must be atomic.
+ *
+ * @conf_tx: Configure TX queue parameters (EDCF (aifs, cw_min, cw_max),
+ *	bursting) for a hardware TX queue. The @queue parameter uses the
+ *	%IEEE80211_TX_QUEUE_* constants. Must be atomic.
+ *
+ * @get_tx_stats: Get statistics of the current TX queue status. This is used
+ *	to get number of currently queued packets (queue length), maximum queue
+ *	size (limit), and total number of packets sent using each TX queue
+ *	(count). This information is used for WMM to find out which TX
+ *	queues have room for more packets and by hostapd to provide
+ *	statistics about the current queueing state to external programs.
+ *
+ * @get_tsf: Get the current TSF timer value from firmware/hardware. Currently,
+ *	this is only used for IBSS mode debugging and, as such, is not a
+ *	required function. Must be atomic.
+ *
+ * @reset_tsf: Reset the TSF timer and allow firmware/hardware to synchronize
+ *	with other STAs in the IBSS. This is only used in IBSS mode. This
+ *	function is optional if the firmware/hardware takes full care of
+ *	TSF synchronization.
+ *
+ * @beacon_update: Setup beacon data for IBSS beacons. Unlike access point,
+ *	IBSS uses a fixed beacon frame which is configured using this
+ *	function.
+ *	If the driver returns success (0) from this callback, it owns
+ *	the skb. That means the driver is responsible to kfree_skb() it.
+ *	The control structure is not dynamically allocated. That means the
+ *	driver does not own the pointer and if it needs it somewhere
+ *	outside of the context of this function, it must copy it
+ *	somewhere else.
+ *	This handler is required only for IBSS mode.
+ *
+ * @tx_last_beacon: Determine whether the last IBSS beacon was sent by us.
+ *	This is needed only for IBSS mode and the result of this function is
+ *	used to determine whether to reply to Probe Requests.

+ * SACK block validation.
+ * ----------------------
+ *
+ * SACK block range validation checks that the received SACK block fits to
+ * the expected sequence limits, i.e., it is between SND.UNA and SND.NXT.
+ * Note that SND.UNA is not included to the range though being valid because
+ * it means that the receiver is rather inconsistent with itself reporting
+ * SACK reneging when it should advance SND.UNA. Such SACK block this is
+ * perfectly valid, however, in light of RFC2018 which explicitly states
+ * that "SACK block MUST reflect the newest segment.  Even if the newest
+ * segment is going to be discarded ...", not that it looks very clever
+ * in case of head skb. Due to potentional receiver driven attacks, we
+ * choose to avoid immediate execution of a walk in write queue due to
+ * reneging and defer head skb's loss recovery to standard loss recovery
+ * procedure that will eventually trigger (nothing forbids us doing this).
+ *
+ * Implements also blockage to start_seq wrap-around. Problem lies in the
+ * fact that though start_seq (s) is before end_seq (i.e., not reversed),
+ * there's no guarantee that it will be before snd_nxt (n). The problem
+ * happens when start_seq resides between end_seq wrap (e_w) and snd_nxt
+ * wrap (s_w):
+ *
+ *         <- outs wnd ->                          <- wrapzone ->
+ *         u     e      n                         u_w   e_w  s n_w
+ *         |     |      |                          |     |   |  |

+ *
+ * Current code wouldn't be vulnerable but it's better still to discard such
+ * crazy SACK blocks. Doing this check for start_seq alone closes somewhat
+ * similar case (end_seq after snd_nxt wrap) as earlier reversed check in
+ * snd_nxt wrap -> snd_una region will then become "well defined", i.e.,
+ * equal to the ideal case (infinite seqno space without wrap caused issues).
+ *
