[PATCH v3 0/6] GEN8+ GPU Watchdog Reset Support

[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.

PATCH v3 of this series was successfully tested from userspace
through an IGT test gem_watchdog --run-subtest basic-bsd1,
that test not in upstream yet.

Also, 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 1 BSD ring.

Michel Thierry (6):
  drm/i915: Add engine reset count in get-reset-stats ioctl

  drm/i915: Watchdog timeout: Ringbuffer command emission for gen8+
  drm/i915: Watchdog timeout: DRM kernel interface to set the timeout
  drm/i915: Watchdog timeout: Include threshold value in error state
  drm/i915: Watchdog timeout: Blindly trust watchdog timeout for reset?
