From d521361755c241a2cfd15e6ce6ef7117e3858f4a Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Wed, 31 Oct 2018 09:28:44 -0700 Subject: [PATCH] drm/i915: Define WA 0870 and kill dead code. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Let's introduce the WA number that is the cause of having NV12 disabled on both SLK and BXT. According to Spec: WA 0870: "Display flickers with NV12 video playback in Y tiling mode. WA: Use YUV422 surface format instead of NV12." v2: remove the useless dead code and consequently avoiding device info flag.
