[PATCH igt v3 07/11] igt/gem_exec_parse: update bitmasks test for v >=8

From: Robert Bragg <robert@sixbynine.org>

Subject: [PATCH igt v3 07/11] igt/gem_exec_parse: update bitmasks test for v >=8
Date: Wed,  9 Nov 2016 16:15:58 +0000	[thread overview]
Message-ID: <20161109161602.2402-8-robert@sixbynine.org> (raw)
In-Reply-To: <20161109161602.2402-1-robert@sixbynine.org>

With v8 of the command parser (where we won't get an EINVAL for an
access violation) this updates the bitmasks test to explicitly confirm
that the command became a NOOP by reading back from where the QW_WRITE
would have otherwise landed.
