Subject: [PATCH v2 10/12] drm/i915/xelpmp: Expose media as another GT
Date: Fri, 2 Sep 2022 16:32:55 -0700 [thread overview]
Message-ID: <20220902233257.3088492-11-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20220902233257.3088492-1-matthew.d.roper@intel.com>
Xe_LPM+ platforms have "standalone media." I.e., the media unit is
designed as an additional GT with its own engine list, GuC, forcewake,
etc. Let's allow platforms to include media GTs in their device info.
v2:
- Simplify GSI register handling and split it out to a separate patch
for ease of review. (Daniele)
