Subject: [PATCH v1 0/6] Add support for sysfs event.cpus and cpu event term
The need for a sysfs event.cpus file is discussed here:
https://lore.kernel.org/lkml/CAP-5=fXXuWchzUK0n5KTH8kamr=DQoEni+bUoo8f-4j8Y+eMBg@mail.gmail.com/
following Dhananjay Ugwekar's work on the RAPL /sys/devices/power PMU.
These changes add support for the event.cpus file in sysfs and also a
cpu event term allowing events to have differing CPUs. This was adding
in order to test the parsing and map propagation for the sysfs case.
Ian Rogers (6):
perf pmu: Merge boolean sysfs event option parsing
perf parse-events: Pass cpu_list as a perf_cpu_map in __add_event
perf pmu: Add support for event.cpus files in sysfs
libperf cpumap: Add ability to create CPU from a single CPU number
perf parse-events: Set is_pmu_core for legacy hardware events
perf parse-events: Add "cpu" term to set the CPU an event is recorded
