[Mesa-dev] [PATCH] i965/skl: Implement WaDisable1DDepthStencil

2015-02-09 Thread Neil Roberts
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). Bugzilla: https://bugs.freedesktop.
