Patch an upstream kernel driver. What's the best way? Proxmox Kernel Sources anywhere?

Hi,
I'm trying to patch a upstream kernel driver (ath.ko). Doing so should be fairly easy even though it seems a bit clumsy. It requires to install the "linux-sources" package from APT, extract the kernel source file that gets downloaded with it, patch it, compile the module and install the patched module. The issue I have is that the kernel-sources downloaded by the "linux-sources" package seems to be from a completely different kernel version nor it seems to be the "-pve" kind of kernel. I tried searching for the git repository but I only found this repo https://git.proxmox.com/?p=pve-kernel.git;a=summary which seems to be including only the patches applied to the kernel.

Is there any way I can find the real "-pve" kernel sources? Or is there a better way to patch an upstream kernel driver?

Please note: With kernel sources I mean the kernel sources and not the kernel headers. The "linux-headers" package does download the proper "-pve" kernel headers.

the 'real' source is included as git submodules. a 'git submodule update --init --recursive' should checkout the relevant git repositories

Hi @dcsapak ,
I'm getting an exception while the modules are checking out:

error: Server does not allow request for unadvertised object 49ccb5a45b29094a53b29ee49b8c9f9f985bb23a
Fetched in submodule path 'submodules/ubuntu-disco', but it did not contain 49ccb5a45b29094a53b29ee49b8c9f9f985bb23a. Direct fetching of that commit failed.


Is there something special that needs to happen for this to work?
Thanks.

Thank you a lot @dcsapak. All seems to be working fine now. Got the modules compiled now and everything seems to be working fine.
