Hi,
I'm trying to interpret some data in Streamline where I'm seeing all 4 big cores (M1/M2 in a Exynos Soc - Samsung S8) show, at times, 100% activity but I've noticed some of them are displaying no cycles. Am I right in assuming they're just spinning? One of those cores seems to be associated with the mali backend. I've attached a couple of images.
Hi JPJ,
I'd normally attribute this to glitchy CPU counter integrations on some kernel versions/devices. If you are seeing "activity" a thread is running and you should also be seeing CPU cycles.
Sorry I can't give a better answer ...

Hi Pete, that's a plausible explanation. On further captures (after I posted this) I've noticed similar patterns where I was missing cycles for 3 out of 4 cores but the activity was registering data. Thanks!
