linux-cpupower-6.2-rc1
This cpupower update for Linux 6.2-rc1 consists of:
- enhancement to choose base_cpu to display default cpupower details
instead of picking cpu 0 and failing show information when it is
offline. This change ensure user will see power information on
the cpu the tool runs on.
- adds Georgian translation to cpupower documentation.
- introduces powercap intel-rapl library, powercap-info command, and
rapl monitor. This adds the ability to show the used power consumption
in for each rapl domain
cpupower: rapl monitor - shows the used power consumption in uj for each rapl domain
This CPU power monitor shows the power consumption
as exposed by the powercap subsystem, cmp with:
Documentation/power/powercap/powercap.rst
cpupower monitor -m RAPL
| RAPL
CPU| pack | core | unco
0|6853926|967832|442381
8|6853926|967832|442381
1|6853926|967832|442381
9|6853926|967832|442381
Unfortunately RAPL domains cannot be directly mapped to the corresponding
CPU socket/package, core it belongs to.
Not sure this is possible at all with the current data exposed from the
kernel.
Still it can be worthful information for developers trying to optimize
power consumption of workloads or their system in general.
