Subject: [PATCH V2 1/6] perf/x86/intel: Add Grand Ridge and Sierra Forest
Date: Mon, 22 May 2023 04:30:35 -0700 [thread overview]
Message-ID: <20230522113040.2329924-1-kan.liang@linux.intel.com> (raw)
From: Kan Liang <kan.liang@linux.intel.com>
The Grand Ridge and Sierra Forest are successors to Snow Ridge. They
both have Crestmont core. From the core PMU's perspective, they are
similar to the e-core of MTL. The only difference is the LBR event
logging feature, which will be implemented in the following patches.
Create a non-hybrid PMU setup for Grand Ridge and Sierra Forest.
