• b916b785a   drivers/perf: kill armpmu_register ... Browse Code »

  Nothing outside of drivers/perf/arm_pmu.c should call armpmu_register
  any more, so it no longer needs to be in include/linux/perf/arm_pmu.h.
  Additionally, by folding it in to arm_pmu_device_probe we can allow
  drivers to override struct pmu fields without getting blatted by the
  armpmu code.

  This patch folds armpmu_register into arm_pmu_device_probe. The logging
  to the console is moved to after the PMU is successfully registered with
  the core perf code.

• fb659882c   drivers/perf: arm_pmu: avoid CPU device_node reference leak ... Browse Code »

  of_cpu_device_node_get increments the reference count on the CPU
  device_node, so we must take care to of_node_put once we've finished
  with it.

  This patch fixes the perf IRQ probing code to avoid the leak.

• fa8ad7889   arm: perf: factor arm_pmu core out to drivers ... Browse Code »

  To enable sharing of the arm_pmu code with arm64, this patch factors it
  out to drivers/perf/. A new drivers/perf directory is added for
  performance monitor drivers to live under.

  MAINTAINERS is updated accordingly. Files added previously without a
  corresponsing MAINTAINERS update (perf_regs.c, perf_callchain.c, and
  perf_event.h) are also added.
