Subject: [PATCH v4 12/18] drm/xe/vsec: Refactor BattleMage PMT defines
Date: Tue,  1 Sep 2026 12:27:47 -0700	[thread overview]
Message-ID: <20260901192736.626777-32-michael.j.ruhl@intel.com> (raw)
In-Reply-To: <20260901192736.626777-20-michael.j.ruhl@intel.com>

Rename generic defines to be BMG specific.
Define several magic numbers.
Add a base offset for more flexibility.
