From: Matt Roper Date: Wed, 11 Mar 2020 16:23:00 +0000 (-0700) Subject: drm/i915: Add Wa_1605460711 / Wa_1408767742 to ICL and EHL X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=34a77b0b7b867d24945be7722ce1543c48161450;p=linux.git drm/i915: Add Wa_1605460711 / Wa_1408767742 to ICL and EHL This workaround appears under two different numbers (and with somewhat confused stepping applicability on ICL). Ultimately it appears we should just implement this for all stepping of ICL and EHL. Note that this is identical to Wa_1407928979:tgl that already exists in our driver too...yet another number referencing the same actual workaround.
