To ensure it supports 192 IBs per submission, so we can keep a simplified IB limit in the follow up patch without having to look at IP or GPU version. Signed-off-by: Bas Nieuwenhuizen <bas@xxxxxxxxxxxxxxxxxxx>
I've took the time and double checked the docs and the maximum size of the ring buffer on GFX6 is indeed only 1MiB.
So even with this change sched_hw_submission can still go as high as 512 without problems (the default is 2 or 4 IIRC).
