Quoting Joonas Lahtinen (2021-05-28 10:25:57) > Hi Dave & Daniel, > > Here's drm-intel-gt-next pull request. > > Most notably it has the reworked DG1 uAPI (behind CONFIG_BROKEN) > as requested. Important fix for Gitlab issues #3293 and #3450 and > one another kernel crash. Adds missing workarounds for Gen11 and > Gen12. Hiding of modparams for compiled-out features. Conversion > to use trylock shrinking for BSW VT-d and BXT. > > Then there are the uAPI kerneldoc improvements as part of the DG1 > uAPI rework. Usual amount smaller fixes, code refactoring and > cleanups as prep for upcoming patches. And includes tag 'topic/intel-gen-to-ver-2021-04-19' (but that is already merged to drm-next).
