Description

Currently we are detecting CPU using MIDR_EL1 value sent from Kernel Driver to user-space.
We want to detect for heterogeneous CPus (where cores might be different) each code's ID. This will help tools like topdown_tool to detect core and apply correct methodology (metrics) for each core.

Definition of done

  • Add to Kernel Driver functionality that will allow detection of the core.
  • Pass raw information to user-space (to wperf) in order to interpret and analysis.
  • Expose detection in wperf test from command line.
