Move the set/list of PMUs code into pmus.[ch]. Clean up hybrid code and remove hybrid PMU list, it is sufficient to scan PMUs looking for core ones. Add core PMU list and perf_pmus__scan_core that just reads core PMUs. Switch code that skips non-core PMUs during a perf_pmus__scan, to use the perf_pmus__scan_core variant. Don't scan sysfs for PMUs if all such PMUs have been previously scanned/loaded. Scanning just core PMUs, for the cases it is applicable, can improve the sysfs reading time by more than 4 fold on my laptop, as servers generally have many more uncore PMUs the improvement there should be larger: ``` $ perf bench internals pmu-scan -i 1000 Computing performance of sysfs PMU event scan for 1000 times Average core PMU scanning took: 989.231 usec (+- 1.535 usec) Average PMU scanning took: 4309.425 usec (+- 74.322 usec) ``` The patch "perf pmu: Separate pmu and pmus" moves and renames a lot of functions, and is consequently large. The changes are trivial, but kept together to keep the overall number of patches more reasonable. v5. Add helper functions for cpumap as suggested by Arnaldo. Fixes missing symbols in importing perf into python, found by building with: https://lore.kernel.org/lkml/20230527055517.2711487-1-irogers@google.com/ v4. On patch 16 (perf pmu: Remove perf_pmu__hybrid_mounted) remove the handling of no cpus for a hybrid core PMU following discussion with Kan: https://lore.kernel.org/lkml/20230524221831.1741381-17-irogers@google.com/ On patch 9 (perf evlist: Propagate user CPU maps intersecting core PMU maps) fix the comment on struct perf_evsel's system_wide variable from conversation with Namhyung: https://lore.kernel.org/lkml/20230524221831.1741381-10-irogers@google.com/ Adds Kan's reviewed-by. v3. Address fixing hybrid user specified CPU maps by doing it in propagate maps. Remove nearly all references to cpu_core/cpu_atom in particular by removing is_pmu_hybrid - hybrid is now >1 core PMU. Addresses comments by Kan and Namhyung. v2. Address Kan's review comments wrt "cycles" -> "cycles:P" and "uncore_pmus" -> "other_pmus".
