[wperf] WPERF-1134: Add CMN events (for all devices) to `wperf list`
Introduction
In this patch I've added support for CMN devices in wperf list. I've used previously implemented "short CMN event name" in [wperf] WPERF-1090: add short CMN event names t... (!828 - merged) this MR to print. We can always change for "original long CMN event names" if needed (they have PMU_ prefix and sometimes _EVENT suffix.
Also minor refactoring, I've added const to few extractors.
I've added some new event type notations (just strings in wperf list):
-
arm_cmn_0//->[Kernel PMU event]or - for Gicen CMN device, e.g.
XP->[CMN XP PMU event].
Also added two new extractors to get data I want:
std::vector<std::pair<cmn_mesh_device_ids, std::wstring>> get_cmn_device_name_list(cmn_mesh_family _mesh_family) const;
std::vector<const cmd_device_event_description*> get_cmn_device_event_list(cmn_mesh_device_ids _device_id, cmn_mesh_family _mesh_family) const;
Example output wperf list
