Subject: [Intel-gfx] [PATCH v3 21/30] drm/i915/dg2: Report INSTDONE_GEOM values in error state
Date: Fri, 23 Jul 2021 10:42:30 -0700 [thread overview]
Message-ID: <20210723174239.1551352-22-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210723174239.1551352-1-matthew.d.roper@intel.com>
Xe_HPG adds some additional INSTDONE_GEOM debug registers; the Mesa team
has indicated that having these reported in the error state would be
useful for debugging GPU hangs. These registers are replicated per-DSS
with gslice steering.
