WebHardware PMU counter limit. When monitoring instruction and cache related perf events (in hw/cache/raw/pmu category of list cmd), these events are mapped to PMU counters on each cpu core. But each core only has a limited number of PMU counters. If number of events > number of PMU counters, then the counters are multiplexed among events, …
WebNov 2, 2007 · PMU: Stands for "Power Management Unit." The PMU is a microcontroller, or integrated circuit , that controls the power functions of Macintosh computers. Though it is not a large component, the PMU contains several parts, including memory , software, firmware , and its own CPU . Some responsibilities of the PMU include: Webhardware, computer machinery and equipment, including memory, cabling, power supply, peripheral devices, and circuit boards. Computer operation requires both hardware and …

CPUs have multiple Performance Monitoring Counters (PMCs) that can count PMU events. You can log those counter values whenever selected ETW events fire.To log the PMC values with ETW events using Windows Performance Recorder (WPR), use element to add the counter and ETW events … See more You can enumerate available PMU events using WPR.exe or Xperf.exe. Only a small subset of PMU events in CPU vendor’s documents are implemented in Windows HAL by default. … See more Besides sampling on time (count down of cycles) with typical sampled profiling, you can also sample the frequency of PMU events such as branch mispredicts, cache misses, or TLB misses.To sample on PMU events in WPR, use … See more Besides the architectural PMU events that you can enumerate through the command (-pmcsources), You can also configure non-architectural PMU events through either WPR custom profile or via registry settings.
