Hi Reshma,

Yes, with pmd-mgmt="monitor" allows AMD power monitor on Genoa.
You can monitor the same using "cpupower -c <n> monitor" tool.

Thanks & Regards,

Hi Sivaprasad,

I am running dpdk l3fwd-power application in "monitor mode" on AMD Genoa using below command.
./dpdk-l3fwd-power -l 1-3 -- -p 0x1 --config="(0,0,2),(0,1,3)" --pmd-mgmt=monitor

Does it allow cores to  use DPDK AMD power monitor support  feature based of mwaitx (https://patchwork.dpdk.org/project/dpdk/patch/20231009140546.862553-3-sivaprasad.tummala@amd.com/)?
If so how do I confirm if the cores are entering implementation dependant C1 State. If any pointers please let me know.

Thanks,
Reshma
