Subject: [Intel-gfx] [PATCH v2 13/13] drm/i915/xehpsdv: Move render/compute engine reset domains related workarounds
Date: Mon, 28 Feb 2022 09:42:45 -0800	[thread overview]
Message-ID: <20220228174245.1569581-14-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20220228174245.1569581-1-matthew.d.roper@intel.com>

From: Srinivasan Shanmugam <srinivasan.s@intel.com>

Registers that exist in the shared render/compute reset domain need to
be placed on an engine workaround list to ensure that they are properly
re-applied whenever an RCS or CCS engine is reset.  We have a number of
workarounds (updating registers MLTICTXCTL, L3SQCREG1_CCS0,
GEN12_MERT_MOD_CTRL, and GEN12_GAMCNTRL_CTRL) that are incorrectly
implemented on the 'gt' workaround list and need to be moved
accordingly.
