We have been having problems with the USB-IF Gold Tree tests when plugging and unplugging devices from the tree. I have seen that the reset-device and configure-endpoint commands, which are invoked from xhci_discover_or_reset_device() and xhci_configure_endpoint(), will sometimes time out. After much debugging, I determined that the commands themselves do not actually time out, but rather their completion events do not get delivered to the right place. This happens when the command ring has just wrapped around, and it's enqueue pointer is left pointing to the link TRB. xhci_discover_or_reset_device() and xhci_configure_endpoint() use the enqueue pointer directly as their command TRB pointer, without checking whether it's pointing to the link TRB. When the completion event arrives, if the command TRB is pointing to the link TRB, the check against the command ring dequeue pointer in handle_cmd_in_cmd_wait_list() fails, so the completion inside the command does not get signaled. The patch below fixes the timeout problem for me. This should be queued for the 2.6.35 and 2.6.36 stable trees.

This patch (as1435) fixes an obscure and unlikely race in ehci-hcd. When an async URB is unlinked, the corresponding QH is removed from the async list. If the QH's endpoint is then disabled while the URB is being given back, ehci_endpoint_disable() won't find the QH on the async list, causing it to believe that the QH has been lost. This will lead to a memory leak at best and quite possibly to an oops. The solution is to trust usbcore not to lose track of endpoints. If the QH isn't on the async list then it doesn't need to be taken off the list, but the driver should still wait for the QH to become IDLE before disabling it. In theory this fixes Bugzilla #20182. In fact the race is so rare that it's not possible to tell whether the bug is still present. However, adding delays and making other changes to force the race seems to show that the patch works.

Andiry's xHCI bus suspend patch introduced the possibly of a host controller replaying old commands on the command ring, if the host successfully restores the registers after a resume. After a resume from suspend, the xHCI driver must restore the registers, including the command ring pointer. I had suggested that Andiry set the command ring pointer to the current command ring dequeue pointer, so that the driver wouldn't have to zero the command ring. Unfortunately, setting the command ring pointer to the current dequeue pointer won't work because the register assumes the pointer is 64-byte aligned, and TRBs on the command ring are 16-byte aligned. The lower seven bits will always be masked off, leading to the written pointer being up to 3 TRBs behind the intended pointer. Here's a log excerpt. On init, the xHCI driver places a vendor-specific command on the command ring: [ 215.750958] xhci_hcd 0000:01:00.0: Vendor specific event TRB type = 48 [ 215.750960] xhci_hcd 0000:01:00.0: NEC firmware version 30.25 [ 215.750962] xhci_hcd 0000:01:00.0: Command ring deq = 0x3781e010 (DMA) When we resume, the command ring dequeue pointer to be written should have been 0x3781e010. Instead, it's 0x3781e000: [ 235.557846] xhci_hcd 0000:01:00.0: // Setting command ring address to 0x3781e001 [ 235.557848] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 64'hffffc900100bc038, 64'h3781e001, 4'hf); [ 235.557850] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 32'hffffc900100bc020, 32'h204, 4'hf); [ 235.557866] usb usb9: root hub lost power or was reset (I can't see the results of this bug because the xHCI restore always fails on this box, and the xHCI driver re-allocates everything.) The fix is to zero the command ring and put the software and hardware enqueue and dequeue pointer back to the beginning of the ring. We do this before the system suspends, to be paranoid and prevent the BIOS from starting the host without clearing the command ring pointer, which might cause the host to muck with stale memory. (The pointer isn't required to be in the suspend power well, but it could be.) The command ring pointer is set again after the host resumes.

If the xHCI host controller shares an interrupt line with another device, the xHCI driver needs to check if the interrupt was generated by its hardware. Unfortunately, the user will see a ton of "Spurious interrupt." lines if the other hardware interrupts often. Lawrence found his dmesg output cluttered with this output when the xHCI host shared an interrupt with his i915 hardware. Remove the warning, as sharing an interrupt is a normal thing. This should be applied to the 2.6.36 stable tree. Signed-off-by: NSarah Sharp <sarah.a.sharp@linux.intel.com> Reported-by: NLawrence Rust <lvr@softsystem.co.uk> Cc: stable@kernel.org

The OCTEON II SOC has USB EHCI and OHCI controllers connected directly to the internal I/O bus. This patch adds the necessary 'glue' logic to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II. The OCTEON normally runs big-endian, and the ehci/ohci internal registers have host endianness, so we need to select USB_EHCI_BIG_ENDIAN_MMIO. The ehci and ohci blocks share a common clocking and PHY infrastructure. Initialization of the host controller and PHY clocks is common between the two and is factored out into the octeon2-common.c file. Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in arch/mips/Kconfig in a following patch.

This commit implements port remote wakeup. When a port is in U3 state and resume signaling is detected from a device, the port transitions to the Resume state, and the xHC generates a Port Status Change Event. For USB3 port, software write a '0' to the PLS field to complete the resume signaling. For USB2 port, the resume should be signaling for at least 20ms, irq handler set a timer for port remote wakeup, and then finishes process in hub_control GetPortStatus.

The appropriate flags are set using the information in the platform data structure. MPC83xx system interface registers are not available on MPC512x, so the access to these registers is isolated in MPC512x case. Furthermore the USB controller clocks must be enabled before 512x register accesses which is done by providing platform specific init callback. The MPC512x internal USB PHY doesn't provide supply voltage. For boards using different power switches allow specifying DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault" properties in the device tree USB nodes.
