Rather than creating partially within the Gallium create function and monkeypatching on draw time with code split across N different files with tight Gallium dependencies, let's streamline everything into a series of maintainable routines in mesa/src/panfrost with no Gallium dependencies, doing the entire texture creation in one-shot and thus adding absolutely zero draw-time overhead (since we can allocate a BO for the descriptor and upload ahead-of-time, so switching textures is as cheap as switching pointers). Was this worth it? You know, I'm not sure :| Signed-off-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Tested-by: Marge Bot <https://gitlab.freedesktop.org/mesa/mesa/merge_requests/3858> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/merge_requests/3858>
