Gen8+ engine-reset

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a rebased on the original patch series from Michel Thierry
that can be found here:

https://patchwork.freedesktop.org/series/21868

Note that this series is only limited to the GPU Watchdog timeout
for execlists as it leaves out support
for GuC based submission for a later time.

The series was also successfully tested from userspace through the
the Intel i965 media driver that is readily found on some
Linux based OS including Ubuntu OS and as well as Chromium OS. The
changes on the i965 media userspace driver are currently under review at

https://github.com/intel/intel-vaapi-driver/pull/429/files

The testbed used on this series included a SKL-based NUC with 
2 BSD rings as well as a KBL-based Chromebook with a 1 BSD ring.
