From fedb2b518239cbc00abcf0d200e0be8436251c11 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 27 Jan 2017 18:03:37 -0800 Subject: perf jevents: Add support for parsing uncore json files Handle the "Unit" field, which is needed to find the right PMU for an event. We call it "pmu" and convert it to the perf pmu name with an uncore prefix. Handle the "ExtSel" field, which just extends the event mask with an additional bit. Handle the "Filter" field which adds parameters to the main event to configure filtering. Handle the "Unit" field which declares the unit the values should be scaled too (similar to what the kernel exports) Set up the "perpkg" field for uncore events so that perf knows they are per package (similar to what the kernel exports) Then output the fields into the pmu-events data structures which are compiled into perf. Filter out zero fields, except for the event itself. v2: Fix compilation. Add uncore_ prefix at pre-processing time. Move eventcode change to separate patch. v3: Remove extra __maybe_unused v4: dont duplicate aliases for cpu pmu events Signed-off-by: Andi Kleen Acked-by: Jiri Olsa Link: http://lkml.kernel.org/r/20170128020345.19007-3-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/pmu-events/pmu-events.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'tools/perf/pmu-events/pmu-events.h') diff --git a/tools/perf/pmu-events/pmu-events.h b/tools/perf/pmu-events/pmu-events.h index 2eaef595d8a0..c669a3cdb9f0 100644 --- a/tools/perf/pmu-events/pmu-events.h +++ b/tools/perf/pmu-events/pmu-events.h @@ -10,6 +10,9 @@ struct pmu_event { const char *desc; const char *topic; const char *long_desc; + const char *pmu; + const char *unit; + const char *perpkg; }; /* -- cgit v1.2.3-55-g7522
