No traces for the cpu during a long period of time (except for entering idle) ?

Two things:

• I want to process data at runtime and start new sample as soon as

isolation gets interrupted.

Traces are good for analysis though and I am using them to check what's interrupting isolated core.

• Second there are cases, like what I reported to you for

ONESHOT_STOPPED bug. These spurious interrupts don't get traced at all..

Mmh, I saw your patch but I thought it was to spot the issue. Even if you enable all the traces, these wakeups are not shown ?
