To improve alias matching, remove the PMU name prefix from the EventName. This will mean that the pmu code will merge aliases, such that we no longer get a huge list of per-PMU events - see perf_pmu_merge_alias(). Also make the following associated changes: - Use "ConfigCode" rather than "EventCode", so the pmu code is not so disagreeable about inconsistent event codes - Add undocumented HHA event codes to allow alias merging (for those events) Signed-off-by: John Garry <john.garry@huawei.com> Acked-by: Ian Rogers <irogers@google.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Leo Yan <leo.yan@linaro.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Shaokun Zhang <zhangshaokun@hisilicon.com> Cc: Will Deacon <will@kernel.org> Cc: linux-arm-kernel@lists.infradead.org Cc: linuxarm@huawei.com Cc: liuqi115@huawei.com Link: https://lore.kernel.org/r/1631795665-240946-6-git-send-email-john.garry@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
