From 4a87492cd137d158779923a034d7e742f7358952 Mon Sep 17 00:00:00 2001 From: "David E. Box" Date: Fri, 12 Jun 2026 14:01:45 -0700 Subject: [PATCH] platform/x86/intel/pmt: Pass discovery index instead of resource MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change PMT class code to pass a discovery index rather than a direct struct resource when creating entries. This allows the class to identify the discovery source generically without assuming PCI BAR resources. For PCI devices, the index still resolves to a resource in the intel_vsec_device. Other discovery sources, such as ACPI, can use the same index without needing a struct resource. Signed-off-by: David E.
