Subject: [Intel-gfx] [PATCH v9 13/15] drm/i915: Disable mmap ioctl for gen12+
Date: Tue,  1 Jun 2021 09:46:52 +0200	[thread overview]
Message-ID: <20210601074654.3103-14-thomas.hellstrom@linux.intel.com> (raw)
In-Reply-To: <20210601074654.3103-1-thomas.hellstrom@linux.intel.com>

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

The platform should exclusively use mmap_offset, one less path to worry
about for discrete.
