Jul 07, 2010 · Server OS: Gentoo Linux Processor: AMD Athlon64 3700 2.4GHZ (Let me know if more info is needed) I need CPU IDLE PM SUPPORT disabled. In 'make menuconfig' of my kernel, I can't disable CPU IDLE PM SUPPORT because something is dependent on it I suppose. Does anyone know what is dependent on it, or can tell me how to find what is dependent on it?

When activating CPU idle support we can see a random slowdown of the system by factor 20-30 (we did a couple of measurements using the tracing infrastructure). Usually handling a timer interrupt takes round about 25us. When the problem triggers this takes up to 650us and theres no idle time left (usually we have 85% idle time)!!

CPU idle time management can be affected by PM QoS in two ways, through the global constraint in the PM_QOS_CPU_DMA_LATENCY class and through the resume latency constraints for individual CPUs. Kernel code (e.g. device drivers) can set both of them with the help of special internal interfaces provided by the PM QoS framework.
