Subject: [PATCH V3 12/15] platform/x86/intel/tpmi: Get OOBMSM CPU mapping from TPMI
Date: Wed,  2 Jul 2025 19:28:27 -0700	[thread overview]
Message-ID: <20250703022832.1302928-13-david.e.box@linux.intel.com> (raw)
In-Reply-To: <20250703022832.1302928-1-david.e.box@linux.intel.com>

Copy TPMI’s OOBMSM platform info into a common area within VSEC private
data via intel_vsec_set_mapping(). This enables other Intel VSEC features
to access the CPU mapping without additional queries.

Additionally, designate the TPMI driver as a supplier for the Telemetry
driver, ensuring it can obtain the necessary platform information for
future feature extensions.
