Hi all,
The other day I installed some newly compiled modules with "make modules_install" from the source three and that action removed already installed nvidia kernel module so I had to rebuild and install it again.
This leads to following question:
I know that kernel can be compiled so that it cant load different versions of the modules (it says so in the help text of the kernel configuration). How come then there is no special place, say /lib/modules/local, for third-party modules so that they can be installed just by copying them there from the distribution archive and doing whatever configuration needed from there on?
This way hardware vendors could just compile the module and distribute it in the binary form. This would also make it easy to upgrade the kernel without having to reinstall all the drivers. What are arguments for and against this approach? Why does the nvidia driver have to be compiled for different kernel versions? Can't they make one module that fits all kernels?
Another question is, if there is a way to compile kernel that loads modules of different versions, why are the modules still installed in "/lib/modules/`uname -r`/*" instead of "/lib/modules/*" by default? In another words. Why is it necessary to upgrade modules with every kerenel release even though some of them might not be in the need there of?
I do understand that many developers have several kernel version installed at the same time but is it possible to share between the versions at least the modules that are not developed as the part of the kernel?
If I'm missing something cruical please point it out to me.
Thanks in advance.
