[PATCH 1/2] drm/i915: Update gen12 forcewake table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The bspec's forcewake page was very stale and out of date for recent
platforms.  The hardware team finally provided us with an updated gen12
table (which applies to TGL, RKL, and DG1) and there are a lot of
changes.
