General Kernel Configuration

This page helps with the configuration of the Linux kernel. Remember, configuring the kernel is easy - you just have to know which hardware you have quite well.

General Information

The kernel sources are unpacked in /usr/src (at least on Gentoo).

• Once you are in the kernel source directory, use the following command to configure graphically your kernel:

make menuconfig

• When migrating to a new kernel, copy your old .config file from the old kernel directory to the new one and type:

make oldconfig

Hardware Detection

• There is a nice link at the Gentoo wiki.

• Basically, emerge pciutils lshw usbutils, which gives you lspci, lshw, and lsusb.

Choice of the scheduler
