Subject: [PATCH v2 0/8] Refactor cpuid and metric table lookup code
Xu Yang <xu.yang_2@....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
