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.
