Subject: [PATCH v7 15/15] platform/x86/intel/pmc: Add NVL PCI IDs for SSRAM telemetry discovery
Date: Wed, 10 Jun 2026 21:34:43 -0700 [thread overview]
Message-ID: <45bed1e4b158778ae0fa8e3db0f020735e14f67c.1781146840.git.david.e.box@linux.intel.com> (raw)
In-Reply-To: <cover.1781146840.git.david.e.box@linux.intel.com>
Add Nova Lake S PMC device IDs to enable binding of the SSRAM telemetry
driver on NVL platforms, and map them to the ACPI-based discovery policy.
Signed-off-by: David E. Box <david.e.box@linux.intel.com>
