Hi Dave & Daniel,
Here goes the first drm-intel-gt-next PR for v6.6.
We have a fix for infinite GPU wait race condition found by CI,
then improved tweakability of RPS algo and fixes to GuC SLPC for
tuning the frequency behavior of the system.
OA report zeroing fix, Aux CCS invalidation fix on Gen12 and
addition of missing W/A for TGL, RKL, DG1, DG2 and ADL.
Then some Meteorlake enabling patches and the usual amount of debugging
and code structure improvements, static checker fixes and fixes for
potential UAF and error handling paths.
Regards, Joonas
PS. Hoping to backmerge drm-next early next week to bring in some
drm-intel-gt-next dependencies before the final PR.
