UbuntuKernel compilation knowledge

UbuntuKernel has a compilation knowledge of 2.1 and is huge in size? The size of the compiled modules is very large, which is 7-8 times larger than that of the modules in the official Kernel. The reason is that Debug is enabled in KernelHacking. Turn it off. Ii. Is Fakeroot fast? Fakeroot does not use multiple lines when making it by itself, and the machines on hand are basically 4-8 cores. You can first make-j4

Ubuntu Kernel compilation knowledge

I. What is the huge size?

The size of the compiled modules is very large, which is 7-8 times larger than that of the modules in the official Kernel.

The reason is that Debug is enabled in Kernel Hacking. Turn it off.

Ii. Is Fakeroot fast?

Fakeroot does not use multiple lines when making it by itself, and the machines on hand are basically 4-8 cores.

You can make-j 4 before fakeroot. When fakeroot calls make, it will skip the compiled items directly.
