[PULL] drm-intel-gt-next

[Tvrtko Ursulin <tursulin@igalia.com>]

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.

Regards,

Tvrtko
