From 5b29b2922afe2b8167a589fc2896a071fc85b693 Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Mon, 2 Feb 2015 17:47:23 +0000 Subject: [PATCH] i965/skl: Implement WaDisable1DDepthStencil Skylake+ doesn't support setting a depth buffer to a 1D surface but it does allow pretending it's a 2D texture with a height of 1 instead. This fixes the GL_DEPTH_COMPONENT_* tests of the copyteximage piglit test (and also seems to avoid a subsequent GPU hang).
