Or is it CX? [Siva] It ll be accounted in "Cx" 1. Are there any specific kernel boot parameter setting we need? to get into MWAITX.

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.tumm...@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
