Dear Experts

I am working on a target that contains quad A53 cores operating at 1GHz. The operating system idle loop contains WFI inline assembly instruction. I know that the Core Clock halts during the WFI instruction which can be seen on the PM_CCNTR…

It can see almost 100% CPU0 usage during the timeline 2.34s ~ 2.42s(in figure 1). How can we know which functions are executed in CPU0/ CPU1 @timeline 2.376s(in figure 2)?

The figure 3 is show the functions sheet @timeline 2.376s, but no more information…
