Subject: [Intel-gfx] [PATCH i-g-t v2 02/11] lib/i915/gem_mman: add fixed mode to mmap__device_coherent
Date: Wed, 28 Jul 2021 11:30:32 +0100	[thread overview]
Message-ID: <20210728103041.1669985-2-matthew.auld@intel.com> (raw)
In-Reply-To: <20210728103041.1669985-1-matthew.auld@intel.com>

On discrete we need to fallback to this mode.
