[PATCH 04/23] drm/i915/mtl: Don't mask off CCS according to DSS fusing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Matt Roper <matthew.d.roper@xxxxxxxxx>

Unlike the Xe_HP platforms, MTL only has a single CCS engine; the
quad-based engine masking logic does not apply to this platform (or
presumably any future platforms that only have 0 or 1 CCS).
