anv/cmd_buffer: Generalize transition_color_buffer
This moves it to being based on layout_to_aux_usage instead of being hard-coded based on bits of a priori knowledge of how transitions interact with layouts. This conceptually simplifies things because we're now using layout_to_aux_usage and layout_supports_fast_clear to make resolve decisions so changes to those functions will do what one expects. There is a potential bug with window system integration on gen9+ where we wouldn't do a resolve when transitioning to the PRESENT_SRC layout because we just assume that everything that handles CCS_E can handle it all the time. When handing a CCS_E image off to the window system, we may need to do a full resolve if the window system does not support the CCS_E modifier. The only reason why this hasn't been a problem yet is because we don't support modifiers in Vulkan WSI and so we always get X tiling which implies no CCS on gen9+. This patch doesn't actually fix that bug yet but it takes us the first step in that direction by making us actually pick the correct resolve op. In order to handle all of the cases, we need more detailed aux tracking. v2 (Jason Ekstrand): - Make a few more things const - Use the anv_fast_clear_support enum v3 (Jason Ekstrand): - Move an assert and add a better comment Reviewed-by: Topi Pohjolainen <[email protected]> Reviewed-by: Nanley Chery <[email protected]>
