Subject: [Intel-gfx] [PATCH v4 04/18] drm/i915/dg2: Update LNCF steering ranges
Date: Thu, 29 Jul 2021 09:59:54 -0700	[thread overview]
Message-ID: <20210729170008.2836648-5-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210729170008.2836648-1-matthew.d.roper@intel.com>

DG2's replicated register ranges are almost the same at XeHP SDV with
the exception of one LNCF sub-range that switches to gslice steering.
We can re-use the XeHP SDV mslice steering table and just provide a
DG2-specific LNCF steering table.
