| |
Power8/Power9 Perforence Monitoring Unit (PMU) supports different sampling modes (SM) such as Random Instruction Sampling (RIS), Random Load/Store Facility Sampling (RLS) and Random Branch Sampling (RBS). Sample mode RLS updates Sampled Instruction Event Register [SIER] bits with memory hierarchy information for a cache reload. Patchset exports the hierarchy information to the user via the perf_mem_data_src object from SIER.
Patchset is a rebase of the work posted previously with minor updates to it.
