Help compiling an unstripped pve vmlinux file

[Trema]

Hey hello!
I require a Linux kernel file containing the debug symbols.

It's the first time I've been having to do this, and have been encountering some trouble in the compiling process.

I compiled it by exporting the debug enabling flag,

DEB_BUILD_PROFILES=pkg.proxmox-kernel.debug

From what I've seen mentioned on here this should be how I get a unstripped kernel image.

Here are the commands I've used to compile the kernel,
git clone https://git.proxmox.com/git/pve-kernel.git
git submodule update --init --recursive
module update --init --recursive
export DEB_BUILD_PROFILES=pkg.proxmox-kernel.debug
make build-dir-fresh
mk-build-deps -ir proxmox-kernel-6.8.x/debian/control
make deb

But when I build I get a dbgsym package with in it a vmlinux at

./usr/lib/debug/boot/vmlinux-6.8.x.x-pve

that's not even 60Mb and when extracted is stripped regardless,

$file vmlinux-6.8.x-x-pve
vvmlinux-6.8.x.x-pve: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, BuildID[sha1]=3de8e31dc7958a78af9dc76c6078152ccc21cdfa, stripped

Like I mentioned before, I'm not very experienced, and hope someone can steer me towards getting the unstripped kernel elf.

seems like something does go wrong there, I'll try to check it out..

I require a Linux kernel file containing the debug symbols.

Wasn't there a repository with the kernel dbg files? I thought I read about this years ago, yet was not able to find it anymore.

 

[fabian]

no, we don't build and publish them to avoid blowing up our CDN space requirements..

One addition, I am also using the git repo to rollback to an older version of the kernel.

could you verify this works for your use case?

Yes it did!! Massive thanks!

great, then I'll submit that as patch for real
