pmu_sync_sampler

A Linux module for PMU sampling that synchronously samples all counters.

Supports Intel and ARM. Tested chips: Intel Xeon 5550 and TI OMAP4460.

  • Intel: mv Makefile.intel Makefile
  • Arm: mv Makefile.arm Makefile

Bugs:

  • Has a crashing bug related to opening the virtual device at the wrong time.
  • For Intel, works on 2.6.32 kernel. 3.2 kernels seem to have some interference with perf_event
