2021-03-24drm/i915/gt: Move the defer_request waiter active assertionChris Wilson1-1/+1
In defer_request() we start with the request we just unsubmitted (that should be the active request on the gpu) and then defer all of its waiters. No waiter should be ahead of the active request, so none should be marked as active. That assert failed. Of particular note this machine was undergoing persistent GPU resets due to underlying HW issues, so that may be a clue. A request is also marked as active when it is retired, regardless of current queue status, and so this assertion failure may be a result of the queue being completed by the reset and then subsequently processed by the tasklet. We can filter out retired requests here by doing the assertion check after the is-ready check (active is a subset of being ready).
