Subject: [PATCH v2 2/7] perf intel-pt: Move PMU initialization from default config code
Date: Thu, 12 Oct 2023 10:56:40 -0700	[thread overview]
Message-ID: <20231012175645.1849503-3-irogers@google.com> (raw)
In-Reply-To: <20231012175645.1849503-1-irogers@google.com>

Avoid setting PMU values in intel_pt_pmu_default_config, move to
perf_pmu__arch_init.
