Subject: [Intel-xe] [PATCH v4 1/5] drm/xe/pat: trim the xelp PAT table
Date: Wed, 27 Sep 2023 12:00:07 +0100 [thread overview]
Message-ID: <20230927110005.291917-8-matthew.auld@intel.com> (raw)
In-Reply-To: <20230927110005.291917-7-matthew.auld@intel.com>
We don't seem to use the 4-7 pat indexes, even though they are defined
by the HW. In the next patch userspace will be able to directly set the
pat_index as part of vm_bind and we don't want to allow setting 4-7.
Simplest is to just ignore them here.
