Subject: [Intel-gfx] [PATCH v3 11/30] drm/i915/xehpsdv: Define steering tables
Date: Fri, 23 Jul 2021 10:42:20 -0700	[thread overview]
Message-ID: <20210723174239.1551352-12-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210723174239.1551352-1-matthew.d.roper@intel.com>

Define and initialize the MMIO ranges for which XeHP SDV requires MSLICE
and LNCF steering.
