Two potential problems, batch re-ordering doesn't really play nicely with fence_server_sync(), so when we switch away from one batch, detect the case that we need to sync, and if so flush. The alternative of trying to track that later batches depend on an earlier batch that had an in-fence is hairy, and the normal use-case would be to sync at the beginning of the frame. But this brings up the second problem, which is that typically we'll get told to sync on an in-fence before the first draw, which means before mesa/st flushes down the framebuffer state to the driver. Which means we don't yet have the correct batch to attach the fence to. So we need to track the in-fence on the context, and transfer it to the batch before draws, etc. Signed-off-by: Rob Clark <robdclark@chromium.org> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6575>
