* sata_fsl: Update RX_WATER_MARK for TRANSCFGPrabhakar Kushwaha2011-03-141-0/+12
| | | | | | | | | | | | | RX_WATER_MARK sets the number of locations in Rx FIFO that can be used before the transport layer instructs the link layer to transmit HOLDS. Note that it can take some time for the HOLDs to get to the other end, and that in the interim there must be enough room in the FIFO to absorb all data that could arrive. Update the new recommended value to 16. Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
* sata_fsl: Fix wrong Device Error Register usagePrabhakar Kushwaha2011-03-141-2/+5
| | | | | | | | | | | | | | | | | | | When a single device error is detected, the device under the error is indicated by the error bit set in the DER. There is a one to one mapping between register bit and devices on Port multiplier(PMP) i.e. bit 0 represents PMP device 0 and bit 1 represents PMP device 1 etc. Current implementation treats Device error register value as device number not set of bits representing multiple device on PMP. It is changed to consider bit level. No need to check for each set bit as all command is going to be aborted.

* ata/pata_arasan_cf: fill dma chan->private from pdata->dma_privViresh Kumar2011-03-142-1/+8
| | | | | | | | | | | Some DMA controllers (eg: drivers/dma/dw_dmac*) allow platform specific configuration for dma transfers. User drivers need to set chan->private field of channel with pointer to configuration data. This patch takes dma_priv data from platform data and passes it to chan->private_data, in order to pass platform specific configuration to DMAC controller.

* libsas: convert to libata new error handlerJames Bottomley2011-03-023-8/+115
| | | | | | | | | | | | | | | | | | The conversion is quite complex given that the libata new error handler has to be hooked into the current libsas timeout and error handling. The way this is done is to process all the failed commands via libsas first, but if they have no underlying sas task (and they're on a sata device) assume they are destined for the libata error handler and send them accordingly. Finally, activate the port recovery of the libata error handler for each port known to the host. This is somewhat suboptimal, since that port may not need recovering, but given the current architecture of the libata error handler, it's the only way; and the spurious activation is harmless.

* libata: separate error handler into usable componentsJames Bottomley2011-03-022-9/+46
| | | | | | | | | | | | | | | | | Right at the moment, the libata error handler is incredibly monolithic. This makes it impossible to use from composite drivers like libsas and ipr which have to handle error themselves in the first instance. The essence of the change is to split the monolithic error handler into two components: one which handles a queue of ata commands for processing and the other which handles the back end of readying a port. This allows the upper error handler fine grained control in calling libsas functions (and making sure they only get called for ATA commands whose lower errors have been fixed up).

* libata: fix eh lockingJames Bottomley2011-03-021-2/+7
| | | | | | | | | | | | The SCSI host eh_cmd_q should be protected by the host lock (not the port lock). This probably doesn't matter that much at the moment, since we try to serialise the add and eh pieces, but it might matter in future for more convenient error handling. Plus this switches libata to the standard eh pattern where you lock, remove from the cmd queue to a local list and unlock and then operate on the local list.

* libata: fix locking for sas pathsJames Bottomley2011-03-021-1/+1
| | | | | | | | | | | | | | For historical reasons, libsas uses the scsi host lock as the ata port lock, and libata always uses the ata host. For the old eh, this was largely irrelevant since the two locks were never mixed inside the code. However, the new eh has a case where it nests acquisition of the host lock inside the port lock (this does look rather deadlock prone). Obviously this would be an instant deadlock if the port lock were the host lock, so switch the libsas paths to use the ata host lock as well.

* libata: plumb sas port scan into standard libata pathsJames Bottomley2011-03-023-25/+24
| | | | | | | | | | | | The function ata_sas_port_init() has always really done its own thing. However, as a precursor to moving to the libata new eh, it has to be properly using the standard libata scan paths. This means separating the current libata scan paths into pieces which can be shared with libsas and pieces which cant (really just the async call and the host scan).

* libata: fix hotplug for drivers which don't implement LPMTejun Heo2011-03-021-1/+1
| | | | | | | | | | | | | | | | | ata_eh_analyze_serror() suppresses hotplug notifications if LPM is being used because LPM generates spurious hotplug events. It compared whether link->lpm_policy was different from ATA_LPM_MAX_POWER to determine whether LPM is enabled; however, this is incorrect as for drivers which don't implement LPM, lpm_policy is always ATA_LPM_UNKNOWN. This disabled hotplug detection for all drivers which don't implement LPM. Fix it by comparing whether lpm_policy is greater than ATA_LPM_MAX_POWER.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IRQ numbering for the IVA and DSP mailboxes was switched due to the wrong ordering in the OMAP2 mbox list. Switch the ordering so DSP is first and matches all the other SoCs. Tested on OMAP2420/n810. Signed-off-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Otherwise we would try to switch the broadcast device into an unsupported mode unconditionally. This went unnoticed so far as the current available broadcast devices support oneshot mode. Seth unearthed this problem while debugging and working around an hpet related BIOS wreckage. Add the necessary check to tick_is_oneshot_available().

They noticed when only 4 bytes were set to 0 instead of 8, everything worked correctly. Mathew pointed out: | | We're supposed to be resetting trampoline_phys_low and | trampoline_phys_high here, which are two 16-bit values. | Writing 64 bits is definitely going to overwrite space | that we're not supposed to be touching. | So limit the area modified to u32.

On a machine with a lot cpus I often saw the last cpu missing. Check for (max) numcpus on every event happening and in the beginning. -> fixes the issue for me.
