Author: Jason Ekstrand <[email protected]> Date: Wed Aug 3 11:41:45 2016 -0700 anv/clear: Clear E5B9G9R9 images as R32_UINT We can't actually clear these images normally because we can't render to them. Instead, we have to manually unpack the rgb9e5 color value on the CPU and clear it as R32_UINT. We still have a bit of work to do to clear non-power-of-two images, but this should get all of the power-of-two clears working on at least Haswell. This fixes three of the new Vulkan CTS tests in the dEQP-VK.api.image_clearing.clear_color_image.* group.
