Subject: [Intel-gfx] [PATCH i-g-t 10/10] gem_wsim: Fix calibration handling
Date: Wed, 17 Jun 2020 17:01:20 +0100	[thread overview]
Message-ID: <20200617160120.16555-11-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20200617160120.16555-1-tvrtko.ursulin@linux.intel.com>

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Intended use case was that run without arguments prints out the
calibrations which can be simply copied and pasted to the -n argument and
things should just work.

Two problems we need to solve: If the print out loops shows zero
calibrations (engine not present) they are later rejected and also if some
calibration is not given it is only an error if it needs to be used
(engine present).
