| |
From: Weilin Wang <weilin.wang@intel.com>
Changes in v5: - Update code about "TakenAlone" to use MSR value instead. Currently, MSR value is used in string format. We are planning to improve this part (maybe use bitmap) in future. [Ian] - Update variable/JSON field names and comments for better readbility [Ian] - Update metricgroup__build_event_string to also use get_too_event_str helper function [Ian]
v4: https://lore.kernel.org/all/20240209031441.943012-1-weilin.wang@intel.com/
Weilin Wang (16): perf stat: Add new field in stat_config to enable hardware aware grouping. perf stat: Add basic functions for the hardware aware grouping perf pmu-events: Add functions in jevent.py to parse counter and event info for hardware aware grouping find_bit: add _find_last_and_bit() to support finding the most significant set bit perf stat: Add functions to set counter bitmaps for hardware-grouping method perf stat: Add functions to get counter info perf stat: Add functions to create new group and assign events into groups perf stat: Add build string function and topdown events handling in hardware-grouping perf stat: Add function to handle special events in hardware-grouping perf stat: Add function to combine metrics for hardware-grouping perf stat: Add partial support on MSR in hardware-grouping perf stat: Handle NMI in hardware-grouping perf stat: Code refactoring in hardware-grouping perf stat: Add tool events support in hardware-grouping perf stat: use tool event helper function in metricgroup__build_event_string perf stat: Add hardware-grouping cmd option to perf stat
