From: Jason Ekstrand Date: Fri, 26 Jul 2019 22:41:59 +0000 (-0500) Subject: isl/formats: R8G8B8_UNORM_SRGB isn't supported on HSW X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7c1b39cf18481f0d15f3ffb1130da4479032d76a;p=mesa.git isl/formats: R8G8B8_UNORM_SRGB isn't supported on HSW On Haswell, the format works but it doesn't properly do an sRGB decode. It appears to act identically to R8G8B8_UNORM. Only Vulkan uses this format so this only affects Vulkan on HSW.
