How to patch kernel to enable CONFIG_TIMER_STATS for 2.6.13-15.13

Hallo Everybody,

My system has now suse/linux/kde 2.6.13-15.13. I want to use powertop which requires CONFIG_TIMER_STATS. Are there anybody know which patch and which other tools I do need, to have CONFIG_TIMER_STATS? I have no experience to patch kernel, could you please guide me or send me any related links?

Thank you very much for your help in advance!

You need to get a kernel with version 2.6.21 or higher (and no patching is necessary). Then, when configuring the kernel, you enable CONFIG_TIMER_STATS (which is under the “Kernel hacking” section, and a sub-option of CONFIG_DEBUG_KERNEL). Also, you don’t want to run this kernel as your everyday kernel (since there is significant overhead with CONFIG_TIMER_STATS).

If you don’t feel like compiling a special debug kernel, you might instead try a precompiled one.
