Subject: [Intel-gfx] [PATCH 2/2] drm/i915/selftests: Check for an initial-breadcrumb in wait_for_submit()
Date: Fri, 15 May 2020 22:57:31 +0100	[thread overview]
Message-ID: <20200515215731.19172-2-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20200515215731.19172-1-chris@chris-wilson.co.uk>

When we look at i915_request_is_started() we must be careful in case we
are using a request that does not have the initial-breadcrumb and
instead the is-started is being compared against the end of the previous
request. This will make wait_for_submit() declare that a request has
been already submitted too early.
