Subject: [Intel-gfx] [PATCH i-g-t 2/4] i915/gem_ctx_engine: Exercise for_each_context_engine() with custom engine[]
Date: Fri, 14 Feb 2020 19:40:14 +0000	[thread overview]
Message-ID: <20200214194016.4054376-2-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20200214194016.4054376-1-chris@chris-wilson.co.uk>

Set up a custom engine map with no engines, and check that the
for_each_context_engine() correctly iterates over nothing.
