Execution time distribution across CPU cluster

Hi,

perfetto ui will show the distribution of a tag slice 's execution time across each CPU core, such as tag **DrawFrame** image bellow, we can see **big/little/medium** time spent on every cpu cluster. BUT


But, not every logic with a tag, such as thread pool or select sched slice across multi tag, the image bellow shows a thread pool that I select all four threads.
We also want to see the distribution of execution time across each CPU core when it fluctuates significantly, to determine whether performance variations are caused by core switching.

So, I would like to know if you have any plans to support this feature.


Start in the Perfetto UI at the existing tag-slice execution-time distribution view across CPU cores, then compare it with the multi-thread thread-pool and multi-tag sched-slice selections described here. Done means showing execution-time distribution by CPU core for those selections, including cases where execution fluctuates across cores.
