Hi Dave, Sima, Here is the main pull request for drm-intel-gt-next targeting 6.11. First is the new userspace API for allowing upload of custom context state used for replaying GPU hang error state captures. This will be used by Mesa (see https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27594) for debugging GPU hangs captured in the wild on real hardware. So far that was only possible under simulation and that via some hacks. Also, simulation in general has certain limitations to what hangs it can reproduce. As the UAPI it is intended for Mesa developers only, it is hidden behind a kconfig and runtime enablement switches. Then there are fixes for hangs on Meteorlake due incorrect reduced CCS configuration and a missing video engine workaround. Then fixes for a couple race conditions in multi GT and breadcrumb handling, and a more robust functional level reset by extending the timeout used. A couple tiny cleanups here and there and finally one back-merge which was required to land some display code base refactoring.
