From: Ville Syrjälä Date: Wed, 21 Jan 2015 17:37:59 +0000 (+0200) Subject: drm/i915: Drop some more CHV pre-production workarounds X-Git-Tag: firefly_0821_release~176^2~1915^2~35^2~136 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=eb973a5e1b780f9f7e1b5b676aaaac75492989bf;p=firefly-linux-kernel-4.4.55.git drm/i915: Drop some more CHV pre-production workarounds Drop WaDisablePwrmtrEvent:chv as it's no longer needed. Also remove the WaSetMaskForGfxBusyness:chv note, but we still leave the GEN6_RP_MEDIA_IS_GFX bit enabled as that's still the recommended setting.
