Subject: [lttng-dev] Monitor user space threads without user events
Date: Sat, 6 Apr 2024 07:20:28 +0300 [thread overview]

Hello,
My user space process contains 2 threads:
First thread is blocked upon a kernel event created by a hardware interrupt
handled by the kernel.
The thread is sending ioctl which is blocked till this interrupt occurs.
Second thread has just a 5msec sleep. It does something and then sleeps for
5msec. Forever.
Is it possible to see when each thread is running (and not blocked or
sleeps) ?
I know how to do it with user events. I wonder if it's possible without any
extra code.
Thank you,
Zvika
