Hello,
I'm really sorry to ask a lot... but I want to make sure that what I did is
right or not
I compared two modes
1. default poll mode
2. interrupt mode (In my understand.. it is kind of an event driven mode in
dpdk)
[Test 1] - poll mode
$ sudo ./examples/dpdk-l3fwd -l 1-3 -n 4 -- -p 0x3 --config="(0,0,1)"
* power: about 36W*
[Test 2] - event driven mode
$ sudo ./examples/dpdk-l3fwd-power -l 1-3 -n 4 -- -p 0x03
--config="(0,0,1)" --interrupt-only
* power: about 12W*
When Idle situation, Test1 uses a core 100% and Test2 doesn't use a core a
lot (almost 0%), so I think I can say "In idle mode, Test2 Mode(event
driven) reduces power by 1/3 compared to poll mode." Is it correct??
BR,
Jaehong Lee
