Subject: [PATCH 0483/1085] usb: xhci: borrow upstream TRB_FETCH quirk on VL805
|
|
hosts
|
|
|
|
This reimplements 5a57342 usb: xhci: add VLI_TRB_CACHE_BUG quirk
|
|
|
|
The downstream implementation required a fair bit of driver surgery to
|
|
allow for truncated ring segments, which needed to shrink by a small
|
|
amount to avoid the cache prefetcher from reading off the end of one
|
|
segment and into another.
|
|
|
|
An upstream implementation for a similar bug on a different controller
|
|
just doubles the size of the memory allocated for ring segments, which
|
|
is a bit more wasteful (+4K per allocation) but means less code churn.
