Subject: [PATCH 3/3] perf/x86/intel/cstate: Add Diamond Rapids support
Date: Mon, 15 Dec 2025 10:25:20 -0800 [thread overview]
Message-ID: <20251215182520.115822-3-zide.chen@intel.com> (raw)
In-Reply-To: <20251215182520.115822-1-zide.chen@intel.com>
From a C-state residency profiling perspective, Diamond Rapids is
similar to SRF and GNR, supporting core C1/C6, module C6, and
package C2/C6 residency counters. Similar to CWF, the C1E residency
can be accessed via PMT only.
