[xhci] Consume event TRB before reporting completion to USB core

2018-02-19T18:59:45+00:00

Reporting a completion via usb_complete() will pass control outside the scope of xhci.c, and could potentially result in a further call to xhci_event_poll() before returning from usb_complete(). Since we currently update the event consumer counter only after calling usb_complete(), this can result in duplicate completions and consequent corruption of the submission TRB ring structures. Fix by updating the event ring consumer counter before passing control to usb_complete(). Reported-by: Andreas Hammarskjöld Tested-by: Andreas Hammarskjöld Signed-off-by: Michael Brown

[xhci] Assume an invalid PSI table if any invalid PSI value is observed

2018-01-29T21:28:12+00:00

Invalid protocol speed ID tables appear to be increasingly common in the wild, to the point that it is infeasible to apply an explicit XHCI_BAD_PSIV flag for each offending PCI device ID. Fix by assuming an invalid PSI table as soon as any invalid value is reported by the hardware. Signed-off-by: Michael Brown

[xhci] Ensure that zero-length packets are not part of a TRB chain

2015-12-07T22:40:47+00:00

Some xHCI controllers (such as qemu's emulated xHCI controller) do not correctly handle zero-length packets that are part of a TRB chain. The zero-length TRB ends up being squashed and does not result in a zero-length packet as seen by the device. Work around this problem by marking the zero-length packet as belonging to a separate transfer descriptor. Signed-off-by: Michael Brown

[usb] Allow additional settling time for out-of-spec hubs

2015-12-07T13:16:47+00:00

Some hubs (e.g. the Avocent Corp. Virtual Hub on a Lenovo x3550 Integrated Management Module) have been observed to require more than the standard 200ms for ports to stabilise, with the result that devices appear to disconnect and immediately reconnect during the initial bus enumeration. Work around this problem by allowing specific hubs an extra 500ms of settling time. Signed-off-by: Michael Brown
