Read out powercap zone information via:
cpupower powercap-info
and show the zone hierarchy to the user:
./cpupower powercap-info
Driver: intel-rapl
Powercap domain hierarchy:
Zone: package-0 (enabled)
Power consumption can be monitored in micro Watts
Zone: core (disabled)
Power consumption can be monitored in micro Watts
Zone: uncore (disabled)
Power consumption can be monitored in micro Watts
Zone: dram (disabled)
Power consumption can be monitored in micro Watts
There is a dummy -a option for powercap-info which can/should be used to
show more detailed info later. Like that other args can be added easily
later as well.
A enable/disable option via powercap-set subcommand is also an enhancement
for later.
Also not all RAPL domains are shown. The func walking through RAPL
subdomains is restricted and hardcoded to: "intel-rapl/intel-rapl:0"
On my system above powercap domains map to:
intel-rapl/intel-rapl:0
-> pack (age-0)
intel-rapl/intel-rapl:0/intel-rapl:0:0
-> core
intel-rapl/intel-rapl:0/intel-rapl:0:1
-> uncore
Missing ones on my system are:
intel-rapl-mmio/intel-rapl-mmio:0
-> pack (age-0)
intel-rapl/intel-rapl:1
-> psys
This could get enhanced in:
struct powercap_zone *powercap_init_zones()
and adopted to walk through all intel-rapl zones, but
also to other powercap drivers like dtpm
(Dynamic Thermal Power Management framework),
cmp with: drivers/powercap/dtpm_*
