VK_IMAGE_LAYOUT_GENERAL already lands on the conservative aux choice for every usage, since anv_layout_to_aux_state() derives that from the layout's usage flags and GENERAL reports all of them, and video images carry no aux at all. So the layout itself needed no work; what the extension does add is a requirement that the host image copy layout lists name every layout it declares interchangeable with GENERAL. Those layouts can only be offered if a host copy is safe in each of them, and the CPU cannot resolve an aux surface on its way to the image. Create images that carry VK_IMAGE_USAGE_HOST_TRANSFER_BIT without one, which makes every layout equivalent for them and vkTransitionImageLayoutEXT a genuine no-op rather than one justified by only ever offering GENERAL. dEQP-VK.video.encode.h264 goes from 18 to 36 passes out of 120, still with no failures: the general_layout variants were the whole gap. dEQP-VK.image.host_image_copy goes from 2037 passes and one failure to 19140 passes and none, the failure having been the properties test checking exactly this list.
