Subject: [PATCH v2 0/8] Refactor cpuid and metric table lookup code
Date: Thu,  7 Nov 2024 08:20:27 -0800	[thread overview]
Message-ID: <20241107162035.52206-1-irogers@google.com> (raw)

Xu Yang <xu.yang_2@nxp.com> reported issues with the system metric
lookup:
https://lore.kernel.org/linux-perf-users/20241106085441.3945502-1-xu.yang_2@nxp.com/
These patches remove a lot of the logic relating CPUIDs to PMUs so
that the PMU isn't part of the question when finding a metric table.
For time reasons, it doesn't go as far as allowing system metrics
without a metric table as a metric table is needed for metrics to
refer to other metrics, and the refactoring of that resolution is a
hassle.

Ian Rogers (7):
  perf header: Move is_cpu_online to numa bench
  perf header: Refactor get_cpuid to take a CPU for ARM
  perf arm64 header: Use cpu argument in get_cpuid
  perf header: Avoid transitive PMU includes
  perf header: Pass a perf_cpu rather than a PMU to get_cpuid_str
  perf jevents: Add map_for_cpu
  perf pmu: Move pmu_metrics_table__find and remove ARM override

Xu Yang (1):
  perf jevents: fix breakage when do perf stat on system metric
