Subject: [PATCH v3 08/25] drm/xe: Add helpers to access PT ops
Date: Fri, 27 Feb 2026 17:34:44 -0800	[thread overview]
Message-ID: <20260228013501.106680-9-matthew.brost@intel.com> (raw)
In-Reply-To: <20260228013501.106680-1-matthew.brost@intel.com>

Add helpers to access PT ops, making it easier to shuffle the location of
the ops structures without requiring widespread code changes.
