The kernel I built is roughly the same size as the Arch one 148M vs 147M.

Sorry by bandwidth I meant mental bandwidth :-)

It's been a long long time since I last ran a patched kernel and I've forgotten everything about how to do it on Archlinux. I can probably build and run a custom kernel if you have an ABS package descriptor. It's adding the lines to apply the patches and so forth that always catches me out.

Re: Memory allocation errors on 6.1.1

I am providing built packages so all you would need to do is

# pacman -U linux-6.3.2.arch1-1.2-x86_64.pkg.tar.zst linux-headers-6.3.2.arch1-1.2-x86_64.pkg.tar.zst

To switch back to the official apckages

# pacman -S linux linux-headers

Thanks for the offer, but I'd only be interested in running a patched kernel that I'd built myself.

Do you have the ABS files around or a diff vs the upstream? I'd be looking to patch 6.3.3.

Re: Memory allocation errors on 6.1.1

I'm going through the docs at https://wiki.archlinux.org/title/Kernel … ild_system it's been a while but I seem to be on track. Will report back later.

Re: Memory allocation errors on 6.1.1

I'm struggling to use the new tools, they are doing too much GPG validation...

==> Verifying source file signatures with gpg...
    archlinux-linux git repo ... SIGNATURE NOT FOUND
==> ERROR: One or more PGP signatures could not be verified!

any ideas? I grabbed the git repo directly because I get gitlab ssh failures when I do

pkgctl repo clone linux

Re: Memory allocation errors on 6.1.1

nevermind,

--skippgpcheck

gets me past that. Which is sad, it should really tell me which key was missing (I added all the keys that were listed in the PKGBUILD)

Re: Memory allocation errors on 6.1.1

$ pkgctl repo clone --unprivileged linux # clone the package using https
$ cd linux
$ gpg --import keys/pgp/* # import the keys

Add the patch to the source array

$ updpkgsums # generate its checksum
$ pkgctl build # build the package

ah, cool. Wish I knew that a few hours ago, the docs seem to need an update.

In any case, it works! This patch does indeed seem to revert the behaviour. Now hopefully it'll make it into the LTS kernels as well.

Do you think there is any chance of convincing the powers-that-be of a 6.3.3-arch2 release including this patch in the meantime?

Not really as the next upstream releases is due Thursday https://lore.kernel.org/stable/20230523 … ation.org/
