Sukadev Bhattiprolu [sukadev@linux.vnet.ibm.com] wrote: | CPUs support a large number of performance monitoring events (PMU events) | and often these events are very specific to an architecture/model of the | CPU. To use most of these PMU events with perf, we currently have to identify | them by their raw codes: | | perf stat -e r100f2 sleep 1 | | This patchset allows architectures to specify these PMU events in JSON | files located in 'tools/perf/pmu-events/arch/' of the mainline tree. | The events from the JSON files for the architecture are then built into | the perf binary. | | At run time, perf identifies the specific set of events for the CPU and | creates "event aliases". These aliases allow users to specify events by | "name" as: | | perf stat -e pm_1plus_ppc_cmpl sleep 1 | | The file, 'tools/perf/pmu-events/README' in [PATCH 16/16] gives more | details. | | Note: | - All known events tables for the architecture are included in the | perf binary. | | - For architectures that don't have any JSON files, an empty mapping | table is created and they should continue to build. | | Thanks to input from Andi Kleen, Jiri Olsa, Namhyung Kim and Ingo Molnar. | | These patches are available from: | | https://github.com:sukadev/linux.git | | Branch Description | ------------------------------------------------------ | json-v16 Source Code only | json-files-6 x86 and Powerpc datafiles only | json-v16-with-data Both code and data (for build/test) Arnaldo, Ingo, I added Andi's patch https://lkml.org/lkml/2015/8/28/521 to 'json-v16' branch. and created a new branch, 'json-files-7' with updated to Intel data files.
