* Intel xhci: Limit number of active endpoints to 64.Sarah Sharp2011-05-274-11/+244
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Panther Point chipset has an xHCI host controller that has a limit to the number of active endpoints it can handle. Ideally, it would signal that it can't handle anymore endpoints by returning a Resource Error for the Configure Endpoint command, but they don't. Instead it needs software to keep track of the number of active endpoints, across configure endpoint commands, reset device commands, disable slot commands, and address device commands. Add a new endpoint context counter, xhci_hcd->num_active_eps, and use it to track the number of endpoints the xHC has active. This gets a little tricky, because commands to change the number of active endpoints can fail. This patch adds a new xHCI quirk for these Intel hosts, and the new code should not have any effect on other xHCI host controllers. Fail a new device allocation if we don't have room for the new default control endpoint. Use the endpoint ring pointers to determine what endpoints were active before a Reset Device command or a Disable Slot command, and drop those once the command completes. Fail a configure endpoint command if it would add too many new endpoints. We have to be a bit over zealous here, and only count the number of new endpoints to be added, without subtracting the number of dropped endpoints. That's because a second configure endpoint command for a different device could sneak in before we know if the first command is completed. If the first command dropped resources, the host controller fails the command for some reason, and we're nearing the limit of endpoints, we could end up oversubscribing the host. To fix this race condition, when evaluating whether a configure endpoint command will fix in our bandwidth budget, only add the new endpoints to xhci->num_active_eps, and don't subtract the dropped endpoints. Ignore changed endpoints (ones that are dropped and then re-added), as that shouldn't effect the host's endpoint resources. When the configure endpoint command completes, subtract off the dropped endpoints. This may mean some configuration changes may temporarily fail, but it's always better to under-subscribe than over-subscribe resources. (Originally my plan had been to push the resource allocation down into the ring allocation functions. However, that would cause us to allocate unnecessary resources when endpoints were changed, because the xHCI driver allocates a new ring for the changed endpoint, and only deletes the old ring once the Configure Endpoint command succeeds. A further complication would have been dealing with the per-device endpoint ring cache.) Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
* Intel xhci: Ignore spurious successful event.Sarah Sharp2011-05-273-0/+20
| | | | | | | | | | | | | | | | | The xHCI host controller in the Panther Point chipset sometimes produces spurious events on the event ring. If it receives a short packet, it first puts a Transfer Event with a short transfer completion code on the event ring. Then it puts a Transfer Event with a successful completion code on the ring for the same TD. The xHCI driver correctly processes the short transfer completion code, gives the URB back to the driver, and then prints a warning in dmesg about the spurious event. These warning messages really fill up dmesg when an HD webcam is plugged into xHCI. This spurious successful event behavior isn't technically disallowed by the xHCI specification, so make the xHCI driver just ignore the spurious completion event.

* Intel xhci: Support EHCI/xHCI port switching.Sarah Sharp2011-05-274-0/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Intel Panther Point chipsets contain an EHCI and xHCI host controller that shares some number of skew-dependent ports. These ports can be switched from the EHCI to the xHCI host (and vice versa) by a hardware MUX that is controlled by registers in the xHCI PCI configuration space. The USB 3.0 SuperSpeed terminations on the xHCI ports can be controlled separately from the USB 2.0 data wires. This switchover mechanism is there to support users who do a custom install of certain non-Linux operating systems that don't have official USB 3.0 support. By default, the ports are under EHCI, SuperSpeed terminations are off, and USB 3.0 devices will show up under the EHCI controller at reduced speeds. (This was more palatable for the marketing folks than having completely dead USB 3.0 ports if no xHCI drivers are available.) Users should be able to turn on xHCI by default through a BIOS option, but users are happiest when they don't have to change random BIOS settings. This patch introduces a driver method to switchover the ports from EHCI to xHCI before the EHCI driver finishes PCI enumeration. We want to switch the ports over before the USB core has the chance to enumerate devices under EHCI, or boot from USB mass storage will fail if the boot device connects under EHCI first, and then gets disconnected when the port switches over to xHCI. Add code to the xHCI PCI quirk to switch the ports from EHCI to xHCI. The PCI quirks code will run before any other PCI probe function is called, so this avoids the issue with boot devices. Another issue is with BIOS behavior during system resume from hibernate. If the BIOS doesn't support xHCI, it may switch the devices under EHCI to allow use of the USB keyboard, mice, and mass storage devices. It's supposed to remember the value of the port routing registers and switch them back when the OS attempts to take control of the xHCI host controller, but we all know not to trust BIOS writers. Make both the xHCI driver and the EHCI driver attempt to switchover the ports in their PCI resume functions. We can't guarantee which PCI device will be resumed first, so this avoids any race conditions. Writing a '1' to an already set port switchover bit or a '0' to a cleared port switchover bit should have no effect. The xHCI PCI configuration registers will be documented in the EDS-level chipset spec, which is not public yet. I have permission from legal and the Intel chipset group to release this patch early to allow good Linux support at product launch. I've tried to document the registers as much as possible, so please let me know if anything is unclear. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

* xhci: STFU: Be quieter during URB submission and completion.Sarah Sharp2011-05-252-37/+15
| | | | | | | | | | | | | | | | | | | | | Unsurprisingly, URBs get submitted and completed a lot in the xHCI driver. If we have to print 10 lines of debug for every URB submitted or completed, then that can cause the whole system to stay in the interrupt handler too long, and can cause Missed Service completion codes for isochronous transfers. Cut down the debugging in the URB submission and completion paths: - Don't squawk about successful transfers, only unsuccessful ones. - Only print the number of bytes transferred if this was a short transfer. - Don't print the endpoint index for successful transfers (will add more debug to failed transfers to show endpoint index there later). - Stop printing MMIO writes. This debugging shows up when the endpoint doorbell is rung a to start a transfer (basically for every URB). - Don't print out the ring enqueue and dequeue pointers - Stop printing when we're pointing to a link TRB.

* xhci: STFU: Don't print event ring dequeue pointer.Sarah Sharp2011-05-251-13/+1
| | | | | | | | | | Stop printing out the event ring dequeue pointer and status register in the operational register set. The host will report an OK status 99% of the time the interrupt handler is called, and usually when it's really hosed, a host controller won't even call the interrupt handler. So the line is really useless. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

| | | | | | | | | | When the xHCI host controller dies, the USB core may attempt to reset the devices to their default configuration before disconnecting them.

* xhci: Clear stopped_td when Stop Endpoint command completes.Sarah Sharp2011-05-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an URB is cancelled, the xHCI driver issues a Stop Endpoint command so that it can manipulate the ring and remove the transfer. The xHC hardware then places a transfer event with the completion code "Stopped" or "Stopped Invalid" to let the driver know what TD it was in the middle of processing. This TD and TRB is stored in ep->stopped_td and ep->stopped_trb. These pointers are also used in handling stalled endpoints. By design, the Stop Endpoint command can race with URB completion. By the time the Stop Endpoint command is handled, the URBs to be cancelled may have been given back to the driver. Unfortunately, the stopped_td and stopped_trb pointers were not getting cleared in this case. The USB core unconditionally tries to reset the toggle bits on any endpoints when a new alternate interface setting is installed. When the xHCI driver saw that ep->stopped_td was still set from the Stop Endpoint command, xhci_reset_endpoint assumed the endpoint was actually stalled, and attempted to clean up the endpoint rings. This would manifest itself in a failed Reset Endpoint command and failed Set TR dequeue Pointer command after a successful Configure Endpoint command. It may have also been causing driver oops when the stopped_td was accessed. This patch should be backported to stable kernels since 2.6.31. Before 2.6.33, stopped_td was found in the xhci_endpoint_ring, not the xhci_virt_ep. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

This one is useful only when working on the main driver or on a subdriver (bug fix, enhancement, new webcam/bridge/sensor or bug fix). It is enabled in the gspca test version which is available from my web site. Signed-off-by: Jean-François Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Unfortunaltely, with time, developers added their stuff into the wrong places. Fix it by moving itens to be at the right place. Also add a new category for sensors and for misc devices that are found only on a certain specific board. While here, fix two bad whitespaces at Kconfig.
