We have testcases to ensure that seqno wraparound works fine, so we can forgo forcing everyone to encounter seqno wraparound during early uptime. seqno wraparound incurs a full GPU stall so not forcing it will eliminate one jitter from the early system. Advancing the global next_seqno after a GPU reset is equally pointless. Signed-off-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx>
The real bug is that seqno wraparound forces GPU idle, can we fix that instead?
