Hi Siva,
Thanks for the information. Could you please clarify below
1. So should we see C1 increment in below stats. Or is it CX?
2. Are there any specific kernel boot parameter setting we need? to get
into MWAITX.
# cpupower -c 2 monitor
| Mperf || Idle_Stats
CPU| C0 | Cx | Freq || POLL | C1 | C2
Thanks,
Reshma

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/[email protected]/)?
If so how do I confirm if the cores are entering implementation dependant C1
State. If any pointers please let me know.
Thanks,
Reshma
