Subject: [PATCH] xhci: add quirk for host controllers that don't
|
|
update endpoint DCS
|
|
|
|
Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints
|
|
at least, if the xHC halts on a particular TRB due to an error then
|
|
the DCS field in the Out Endpoint Context maintained by the hardware
|
|
is not updated with the current cycle state.
|
|
|
|
Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
|
|
from the TRB that the xHC stopped on.
|
|
|
|
