[PATCH 02/21] drm/i915/tgl: Fix macros for TGL SOC based WA

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

 



Fix macros for applying TGL SOC WAs by using INTEL_REVID()
as index to fetch correct revision offset in TGL GT/DISP stepping
table.

Also, remove redundant macros and simplify it to use GT and DISP
macros for getting applicable stepping for TGL.
