While reworking image resolves completely in RADV, I found a very weird bug where the only fix was to emit caches immediately after decompressing the source resolve image (after FMASK_DECOMPRESS). I have been struggling this for few hours and figured that it was something related to context rolls (ie. as long the context was rolled out, emitting the flushes immediately was required). It turns out this was a known hardware bug on GFX6 that was implemented in PAL. Though PAL only applies on GFX6 but GFX7-8 are also affected based on my testing. Note that RadeonSI flushes CB_META too. Cc: mesa-stable Signed-off-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/39959> |
