There are several facilities to see where the kernel spends its resources. A simple one is the profiling function, that stores the current EIP (instruction pointer) at each clock tick. Boot the kernel with command line option profile=2 (or some other number instead of 2). This will cause a …

enabling Kernel lock profiling support. To build a new Kernel including a new compile-time enabled feature, a new Kernel profile must be created. The Kernel profile is the compile-time configuration file.

Your kernel is likely to support halting the processor when a CPU is idle. As the typical hardware events like CPU_CLK_UNHALTED do not count when the CPU is halted, the kernel profile will not reflect the actual amount of time spent idle. You can change this behaviour by booting with the idle=poll option, which uses a different idle routine.

Kernel probes is a dynamic debugging and profiling mechanism that allows you to break into kernel code, invoke your custom function called probe and return everything back. Basically, it’s done by writing kernel module where you register a handler for some address or symbol in kernel code.

https://en.wikipedia.org/wiki/OProfile
The most widely supported kernel mode of oprofile uses a system timer (See: Gathering profiling events). However, this mode is unable to measure kernel functions where interrupts are disabled. Newer CPU models support a hardware performance counter mode which uses hardware logic to record events without any active code needed.License: GPL
