any particular reason why approximately all tracers in the kernel are not compiled as modules by default in 2.6.32rc? In particular, I'm interested in the sysprof tracer, because I use sysprof every now and then. I checked the config, and all CONFIG_*_TRACER are not set.
I don't see the reasoning behind that ATM, as the according tracer can only be loaded and activated by root.
I also don't know the reason, but doesn't perf work enough for you?
Not even close. You need to recompile for perf, it only profiles a single application, output is unreadable.
Are we talking about the same /usr/bin/perf packaged in 11.2? I can't see why (for the -trace flavor) CONFIG_*_TRACER should not be enabled. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
