Subject: [PATCH 3/6] platform/x86:intel/pmc: Add DMU GUID to Arrow Lake U/H
Date: Tue, 14 Oct 2025 14:45:31 -0700 [thread overview]
Message-ID: <20251014214548.629023-4-xi.pardee@linux.intel.com> (raw)
In-Reply-To: <20251014214548.629023-1-xi.pardee@linux.intel.com>
Arrow Lake U/H platforms may have multiple GUIDs pointing to the
same telemetry region. Add the second possible GUID to the GUID
list to support the Arrow Lake U/H platforms with this GUID.
