      perf/cgroups: Don't rotate events for cgroups unnecessarily · fd7d5517
      Ian Rogers authored
      Currently perf_rotate_context assumes that if the context's nr_events !=
      nr_active a rotation is necessary for perf event multiplexing. With
      cgroups, nr_events is the total count of events for all cgroups and
      nr_active will not include events in a cgroup other than the current
      task's. This makes rotation appear necessary for cgroups when it is not.
      
      Add a perf_event_context flag that is set when rotation is necessary.
      Clear the flag during sched_out and set it when a flexible sched_in
      fails due to resources.

      perf/x86/rapl: Get quirk state from new probe framework · 637d97b5
      Jiri Olsa authored
      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.

      We no longer need model specific attribute arrays,

      perf/x86/rapl: Get MSR values from new probe framework · 122f1c51
      Jiri Olsa authored
      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.

      the MSR and cstate module design.
      
      It will replace the current rapl_cpu_match device
      table and detection code in following patches.

      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
