From: Chad Versace <chad.vers...@intel.com> Begin implementing HiZ for Gen >= 5. Since it's incomplete, the patch series leaves HiZ disabled default. But you can force enable it with env INTEL_USE_HIZ=1.
I did a full Piglit run on Gen 5 and found no regressions. These patches live on my personal hiz branch. What doesn't work ----------------- * Rendering to a window framebuffer with depth or stencil attachment. * Rendering to an FBO with GL_DEPTH_STENCIL_ATTACHMENT. * HiZ/depth resolves. What does work -------------- * Rendering to an FBO with GL_DEPTH_ATTACHMENT and no GL_STENCIL_ATTACHMENT. * Rendering to an FBO with GL_DEPTH_ATTACHMENT and GL_STENCIL_ATTACHMENT.
