File perf-vendor-events-Remove-bad-jaketown-uncore-events.patch of Package perf
From: Ian Rogers <irogers@google.com> Date: Thu, 4 Aug 2022 18:38:56 -0700 Subject: perf vendor events: Remove bad jaketown uncore events Git-commit: b48ddbbb99986de85878a34c23ecebac22a59b79 Patch-mainline: v6.0-rc1 References: SLE15-SP5 - update json files The event converter scripts at: https://github.com/intel/event-converter-for-linux-perf passes Filter values from data on 01.org that is bogus in a perf command line and can cause perf to infinitely recurse in parse events. Remove such events or filters using the updated patch: https://github.com/intel/event-converter-for-linux-perf/pull/15/commits/afd779df99ee41aac646eae1ae5ae651cda3394d Fixes: 376d8b581b7639c9 ("perf vendor events: Update Intel jaketown") Reviewed-by: Kan Liang <kan.liang@linux.intel.com> Signed-off-by: Ian Rogers <irogers@google.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Caleb Biggers <caleb.biggers@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kshipra Bopardikar <kshipra.bopardikar@intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Perry Taylor <perry.taylor@intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Xing Zhengjun <zhengjun.xing@linux.intel.com> Link: https://lore.kernel.org/r/20220805013856.1842878-4-irogers@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Tony Jones <tonyj@suse.de> --- .../pmu-events/arch/x86/jaketown/uncore-cache.json | 30 ---------------------- .../pmu-events/arch/x86/jaketown/uncore-other.json | 13 ---------- .../pmu-events/arch/x86/jaketown/uncore-power.json | 11 -------- 3 files changed, 54 deletions(-) diff --git a/tools/perf/pmu-events/arch/x86/jaketown/uncore-cache.json b/tools/perf/pmu-events/arch/x86/jaketown/uncore-cache.json index cf28ffa778ba..351f8b040ed1 100644 --- a/tools/perf/pmu-events/arch/x86/jaketown/uncore-cache.json +++ b/tools/perf/pmu-events/arch/x86/jaketown/uncore-cache.json @@ -20,7 +20,6 @@ "Counter": "0,1", "EventCode": "0x34", "EventName": "UNC_C_LLC_LOOKUP.DATA_READ", - "Filter": "CBoFilter[22:18]", "PerPkg": "1", "PublicDescription": "Counts the number of times the LLC was accessed - this includes code, data, prefetches and hints coming from L2.
