From 7bdccd104bf49861adfd891ea35884f2197e1c44 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Wed, 3 Aug 2016 11:41:45 -0700 Subject: 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.
