Where to find extended information about menuconfig
options?
I am especially interested in those related with improving latency/jitter of a RT_PREEMT
kernel (apart of the obvious CONFIG_PREEMPT_RT_FULL
).
Some context
Trying to improve the Jitter of a RT_PREEMPT
kernel, I need to understand deeply some of the configuration options of the kernel, those available with menuconfig
command line.
After searching on Internet, I found only the one-line description already available in the menuconfig
interface. But due to my "low" knowledge of the kernel, most of them stay obscure to me, or at least not fully clear.
The project consists of building a real time software on a small one-board computer, but after patching the kernel and building everything, I still get quite random jitter (speaking of up to 0.5ms under load, when I would need 0.050ms or less)
