Subject: [linux-audio-dev] oprofile, redhat and CONFIG_PREEMPT

Hi, all.
We want to run oprofile on our redhat 8 based system. It looks like
great technology, but an oprofile FAQ says it doesn't work on redhat 8
systems.
The FAQ recommends downloading a redhat's oprofile rpm, which we did.
But that is configured not to work with a CONFIG_PREEMPT kernel. Our
kernel is CONFIG_PREEMPT patched for increased audio performance.
Yikes!
Has anyone run in to this problem and found a clever solution? An
alternate profiler that works? Will we get meaningful results if we
rebuild the kernel with CONFIG_PREEMPT turned off? Or perhaps we can run
it with CONFIG_PREEMPT on and see what happens?
Cheers...
