[Intel-gfx] [PATCH v3 11/14] drm/i915/mtl: Add gsi_offset when emitting aux table invalidation

Matt Roper
2022-09-06T23:50:53Z

The aux table invalidation registers are a bit unique --- they're
engine-centric registers that reside in the GSI register space rather
than within the engines' regular MMIO ranges. That means that when
issuing invalidation on engines in the standalone media GT, the GSI
offset must be added to the regular MMIO offset for the invalidation
registers.
