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.
