Subject: [PATCH v2 3/5] drm/xe/guc: Add PF2GUC_UPDATE_VGT_POLICY to ABI
Date: Wed, 10 Apr 2024 19:03:36 +0200	[thread overview]
Message-ID: <20240410170338.1199-4-michal.wajdeczko@intel.com> (raw)
In-Reply-To: <20240410170338.1199-1-michal.wajdeczko@intel.com>

In upcoming patches the PF driver will add support to change GuC
policies and will need to use PF2GUC_UPDATE_VGT_POLICY messages.
Add necessary definitions to our GuC firmware ABI header.
