fs/resctrl: Provide interface to update the event configurations
When "mbm_event" counter assignment mode is enabled, users can modify the
event configuration by writing to the 'event_filter' resctrl file. The event
configurations for mbm_event mode are located in
/sys/fs/resctrl/info/L3_MON/event_configs/.
Update the assignments of all CTRL_MON and MON resource groups when the event
configuration is modified.
Example:
$ mount -t resctrl resctrl /sys/fs/resctrl
$ cd /sys/fs/resctrl/
$ cat info/L3_MON/event_configs/mbm_local_bytes/event_filter
local_reads,local_non_temporal_writes,local_reads_slow_memory
$ echo "local_reads,local_non_temporal_writes" >
info/L3_MON/event_configs/mbm_total_bytes/event_filter
$ cat info/L3_MON/event_configs/mbm_total_bytes/event_filter
local_reads,local_non_temporal_writes
