Subject: [PATCH 6/7] drm/xe/guc: Add VF2GUC_QUERY_SINGLE_KLV to ABI
Date: Thu, 28 Mar 2024 19:31:46 +0100	[thread overview]
Message-ID: <20240328183147.495-7-michal.wajdeczko@intel.com> (raw)
In-Reply-To: <20240328183147.495-1-michal.wajdeczko@intel.com>

In upcoming patches the VF driver will add support to read its
configuration from the GuC using special H2G actions.
Add necessary definitions to our GuC firmware ABI header.
