I've tested on GLK, KBL, CFL Intel NUC devices and got the following
performance results, there is no performance regression per my testing.
and CI build test has passed as well.

Hi Rong,
Please help to trigger 3D performance test on several Gen9 CI test boxes which
different fusing sku with/without “patch v5”, and share the results. Thanks,

Hi Tvrtko,
This WaProgramMgsrForCorrectSliceSpecificMmioReads info can be found on bspec
WA#0575 and it's necessary for GT subslice fuse sku on PC7 exit case while
running VP8 hw encode, it impacted CrOS projects since google disabled VP8 HW
encode feature on Gen9 sku, so that's why we need this
gards,

Thanks Ville,
I'll backport your patch (drm/i915/vbt: Fix HDMI level shifter and max data
rate bitfield sizes) to CrOS kernel for resolving this issue. Please abandon my
patch.
