how to install a kernel patch?
 

Hi


How to I install a kernel patch, and do I have to re-compile the kernel after the patching?

kernel patches are for the source tree. use the "patch" command to apply it to the kernel source. and yes, you have to recompile anytime you apply a patch ( for kernels, apps, etc...)

an example:

cd <some source directory> ( we'll assume the patch is uncompressed and in the source directory)
patch -Np1 -i < patch name >

the number after -Np does make a difference, most of the time it's either a 0 or a 1. if one fails ( if it ask you what file to patch, it failed), change the number.
