Subject: [Questions] How to run 'perf top' on ARM to profile kernel functions with modules loaded
Date: Wednesday, November 10, 2010 - 11:56 pm

Hi,

'perf top' can't display any functions when modules are loaded on ARM.

But if all modules are unloaded, everything is OK and kernel functions can be
displayed.

So how can I make 'perf top' to profile kernel functions when modules are loaded
on ARM?

thanks,
