Subject: [Intel-gfx] [RESUBMIT PATCH 1/2] tests/gem_userptr_blits: Refresh readonly-mmap-unsync exercise
Date: Mon, 16 Mar 2020 09:45:42 +0100	[thread overview]
Message-ID: <20200316084543.15421-2-janusz.krzysztofik@linux.intel.com> (raw)
In-Reply-To: <20200316084543.15421-1-janusz.krzysztofik@linux.intel.com>

Upgrade the subtest to use MMAP_GTT API v4 (aka MMAP_OFFSET),
dynamically examine each mapping type supported by i915 driver.
