Subject: [PATCH 3/6] perf/x86/intel: Factor out the initialization code for ADL e-core
Date: Tue, 29 Aug 2023 05:58:03 -0700 [thread overview]
Message-ID: <20230829125806.3016082-4-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20230829125806.3016082-1-kan.liang@linux.intel.com>
From: Kan Liang <kan.liang@linux.intel.com>
From PMU's perspective, the ADL e-core and newer SRF/GRR have a similar
uarch. Most of the initialization code can be shared.
Factor out intel_pmu_init_grt() for the common initialization code.
The common part of the ADL e-core will be replaced by the later patch.
