From 423ee8e99aa5ee7ee5133616366099b8379870dc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 3 Jul 2019 23:08:20 +0300 Subject: [PATCH] drm/i915: Disable sprite gamma on ivb-bdw MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We don't currently have any use for the sprite gamma on ivb-bdw. Let's disable it. We already do that on skl+. On pre-ivb there is no way to disable the sprite gamma, and it only affects YCbCr pixel formats, whereas on ivb+ it also affects RGB formats.
