[edk2] [PATCH 0/3] Check timeout URB again after stopping endpoint
Posted by Ruiyu Ni 8 years, 4 months ago 
This fixes BULK data loss when transfer is detected as timeout but
finished just before stopping endpoint.

Ray,

Does XhciPei need the same update?


Thanks,
Star

Re: [edk2] [PATCH 0/3] Check timeout URB again after stopping endpoint
Posted by Ni, Ruiyu 8 years, 4 months ago 
This patch supports a certain USB device that:
1. contain BULK IN endpoint
2. BULK read from HOST gets timeout if
    a. there is no data from the endpoint in the device
    b. the data comes late

For now, I haven't found any other USB devices that meet the above conditions
except the Bluetooth host controller.
Given the fact PEI USB functionality is merely to support USB storage access,
I don't have chance to test in PEI phase if I made the similar change.

So I don't prefer to update the PEI XHCI module.

If we need to update PEI XHCI in future, we could do a "cherry-pick" later,
with necessary unit test.

Thanks/Ray
