Subject: [PATCH v7 08/24] drm/xe: Add helpers to access PT ops
Date: Thu, 24 Sep 2026 21:53:04 -0700 [thread overview]
Message-ID: <20260925045320.1325860-9-matthew.brost@intel.com> (raw)
In-Reply-To: <20260925045320.1325860-1-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.
