[PATCH 8/8] perf/x86/rapl: Get quirk state from new probe framework

Getting the apply_quirk bool from new rapl_model_match array. And because apply_quirk was the last remaining piece of data in rapl_cpu_match, replacing it with rapl_model_match as device table. The switch to new perf_msr_probe detection API is done. Signed-off-by: Jiri Olsa --- arch/x86/events

[PATCHv3 0/8] perf/x86: Rework msr probe interface

hi, following up on [1], [2] and [3], this patchset adds update attribute groups to pmu, factors out the MSR probe code and use it in msr,cstate* and rapl PMUs. The functionality stays the same with one exception: for msr PMU: the event is not exported if the rdmsr return zero on event's msr, csta

[PATCH 1/8] perf/x86: Add msr probe interface

Adding perf_msr_probe function to provide interface for checking up on MSR register and set the related attribute group visibility. User defines following struct for each MSR register: struct perf_msr { u64 msr; struct attribute_group *grp; bool

[PATCH 3/8] perf/x86/cstate: Use new probe function

Using perf_msr_probe function to probe for cstate events. The functionality is the same, with one exception, that perf_msr_probe checks for rdmsr to return value != 0 for given MSR register. Using the new attribute groups and adding the events via pmu::attr_update. Signed-off-by: Jiri Olsa ---

[PATCH 4/8] perf/x86/rapl: Use new msr detection interface

Using perf_msr_probe function to probe for rapl msrs. Adding new rapl_model_match device table, that gathers events info for given model, following the msr and cstate module design. It will replace the current rapl_cpu_match device table and detection code in following patches. Signed-off-by: Ji

[PATCH 5/8] perf/x86/rapl: Get rapl_cntr_mask from new probe framework

[PATCH 6/8] perf/x86/rapl: Get msr values from new probe framework

There's no need to have special code for getting the bit and msr value for given event. We can now easily get it from rapl_msrs array. Also getting rid of RAPL_IDX_*, which is no longer needed and replacing INTEL_RAPL* with PERF_RAPL* enums. Signed-off-by: Jiri Olsa --- arch/x86/events/intel/ra
