Subject: [Intel-gfx] [PATCH v3 12/30] drm/i915/xehpsdv: Define MOCS table for XeHP SDV
Date: Fri, 23 Jul 2021 10:42:21 -0700	[thread overview]
Message-ID: <20210723174239.1551352-13-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210723174239.1551352-1-matthew.d.roper@intel.com>

From: Lucas De Marchi <lucas.demarchi@intel.com>

Like DG1, XeHP SDV doesn't have LLC/eDRAM control values due to being a
dgfx card. XeHP SDV adds 2 more bits: L3_GLBGO to "push the Go point to
memory for L3 destined transaction" and L3_LKP to "enable Lookup for
uncacheable accesses".

Bspec: 45101
