Subject: [PATCH v4 0/6] Make evlist CPUs more accurate
Date: Fri, 29 Apr 2022 23:23:18 -0700 [thread overview]
Message-ID: <20220430062324.1565215-1-irogers@google.com> (raw)
Based on the thread:
https://lore.kernel.org/linux-perf-users/CAP-5=fVMHzTfKdpWMXtbtx7t14u2f4WzNak+F0Q93cQ7CZfhbg@mail.gmail.com/
First patch is a cherry-pick to avoid a conflict of:
https://lore.kernel.org/linux-perf-users/20220414014642.3308206-2-irogers@google.com/
Second patch makes all_cpus more accurate when there are command line CPUs.
The third patch fixes perf stat metric-only output for uncore metrics.
The fourth patch makes cleans up merging of dummy CPU maps.
The fifth and sixth patch try to make user_requested_cpus and all_cpus
clearer with documentation and by renaming all_cpus.
The code no longer needs to add an intersect function and so the API
is removed and the merged API left unchangaged.
Ian Rogers (6):
perf cpumap: Switch to using perf_cpu_map API
perf evlist: Clear all_cpus before propagating
perf stat: Avoid printing cpus with no counters
perf cpumap: Handle dummy maps as empty in subset
perf evlist: Add to user_requested_cpus documentation
perf evlist: Rename all_cpus
