Subject: [igt-dev] [RFT i-g-t 5/6] lib: igt_dummyload: use for_each_context_engine()
Date: Thu, 11 Apr 2019 13:28:31 +0100	[thread overview]
Message-ID: <20190411122831.1787-1-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20190408161533.2421-6-andi.shyti@intel.com>

From: Andi Shyti <andi.shyti@intel.com>

With the new getparam/setparam api, engines are mapped to
context. Use for_each_context_engine() to loop through existing
engines.

Just some debug to get more data from CI.
