radv: detect command buffers that do no work and drop them (v2)
If a buffer is just full of flushes we flush things on command buffer submission, so don't bother submitting these. This will reduce some CPU overhead on dota2, which submits a fair few command streams that don't end up drawing anything. v2: reorganise loop to count first then malloc, rename some vars (Bas) Reviewed-by: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> Signed-off-by: Dave Airlie <airlied@redhat.com>
