| H A D | monitor.c | d507f83c Fri Jan 13 09:20:34 CST 2023 Babu Moger <babu.moger@amd.com> x86/resctrl: Support monitor configuration
Add a new field in struct mon_evt to support Bandwidth Monitoring Event
Configuration (BMEC) and also update the "mon_features" display.
The resctrl file "mon_features" will display the supported events
and files that can be used to configure those events if monitor
configuration is supported.
Before the change:
$ cat /sys/fs/resctrl/info/L3_MON/mon_features
llc_occupancy
mbm_total_bytes
mbm_local_bytes
After the change when BMEC is supported:
$ cat /sys/fs/resctrl/info/L3_MON/mon_features
llc_occupancy
mbm_total_bytes
mbm_total_bytes_config
mbm_local_bytes
mbm_local_bytes_config
