From d9cf4308ceea3762c1aab48f9c48e12a72162b5a Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Tue, 28 Aug 2018 15:25:23 -0500 Subject: [PATCH] i965/screen: Allow modifiers on sRGB formats This effectively reverts a26693493570a9d0f0fba1be617e01ee7bfff4db which was a misguided attempt at protecting intel_query_dma_buf_modifiers from invalid formats. Unfortunately, in some internal EGL cases, we can get an SRGB format validly in this function. Rejecting such formats caused us to not allow CCS in some cases where we should have been allowing it. This regressed the performance of some SynMark tests as well as GfxBench ALU2, Tessellation and Manhattan 3.0 tests There's some question of whether or not we really should be using SRGB "fourcc" formats that aren't actually in drm_foucc.h but there's not much harm in allowing them through here.
