• ARMv8.2 Statistical Profiling Extension (SPE) Performance Monitor Units (PMU)

ARMv8.2 introduces the optional Statistical Profiling Extension for collecting
performance sample data using an in-memory trace buffer.

** SPE Required properties:

• compatible : should be one of:

       "arm,statistical-profiling-extension-v1"
  

• interrupts : Exactly 1 PPI must be listed. For heterogeneous systems where

           SPE is only supported on a subset of the CPUs, please consult
       the arm,gic-v3 binding for details on describing a PPI partition.
  

** Example:

spe-pmu {
compatible = “arm,statistical-profiling-extension-v1”;
interrupts = <GIC_PPI 05 IRQ_TYPE_LEVEL_HIGH &part1>;
};
