perf vendor events arm64: Revise core JSON events for eMAG
Split the PMU events into meaningful functional groups. Update core pmu events based on supported ARMv8 recommended IMPLEMENTATION DEFINED events. The JSON files are updated with reference to a PMU table shared here: https://github.com/AmpereComputing/ampere-centos-kernel/blob/amp-centos-7.5-kernel/Documentation/arm64/eMAG-ARM-CoreImpDefined.pdf Changes in v3: - Removed CHAIN event as it wouldn't be useful in Perf - William - Will factor out events 0x00-0x38 in a follow-on patch - William - to armv8-recommended.json Changes in V2: - Provided documentation for changes - John, William - Broke up into meaningful groups - William Signed-off-by: Sean V Kelley <seanvk.dev@oregontracks.org> Reviewed-by: William Cohen <wcohen@redhat.com> Cc: John Garry <john.garry@huawei.com> Cc: linux-arm-kernel@lists.infradead.org LPU-Reference: 20180916221203.7935-1-seanvk.dev@oregontracks.org Link: https://lkml.kernel.org/n/tip-tzvs1ip6srcv2et0ny58e0wy@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
