| |
Hi all, I want to ensure I understand the status of the kernel right now. When I enable
[*] Interrupts-off critical section latency timing
I immediately see values as shown below. I think that this is the timer, which I have set to 1000HZ and not a rela latency. Is that correct?
If my understanding is correct then is there someone that can spend some time and look into this? Is this an x86_64 issue only?
Thanks, Mark
