Configure a Linux kernel using make xconfig and find configuration variable definitions.
- Let's talk about making xconfig.…A different way to configure the kernel…a mouse oriented one.…You get to click around.…So, with make xconfig, you can click to expand…or contract the options.…With make xconfig, you'll see that in the little box,…a module is a dot.…So if you click in the box and you get a dot,…it means you want it to be a module.…If you click in the box and you get a checkmark,…that means you want it statically linked in the kernel.…And of course, empty means you don't have that configured.…
Xconfig is really pretty good for searching.…Underneath the edit menu, you have find…and you can type a string in there and it will pop…up all the config options that have that string.…And then even cooler, you can go ahead and just do…the configuration in the pop up window.…You can select an item and make it a module or not,…you don't have to go find it in the tree.…Although when you select it in the result option,…it does scroll to find it in the tree for you, too.…Another nice feature of make xconfig that I really like,…
We survey the Linux kernel specification, boot process, and loadable kernel modules. You will practice techniques such as downloading and searching Linux kernel source code and configuring a Linux kernel from scratch. Challenge and solution videos at the end of almost every chapter allow you to test your new Linux skills along the way.
