I don't quite agree with calling it just a development repository. It is the main repository for the Asahi Linux fork where releases are tagged which are then packaged in their official ALARM (and soon Fedora) distributions and also used by the unofficial ports listed here: https://github.com/AsahiLinux/docs/wiki/SW%3AAlternative-Distros You are right that there is work to upstream those changes, but the diff is not small and I don't think the upstream support is at a point where it is actually usable. I wouldn't mind updating the Upstream Authors field if you think there is a better name to put there. > > Is there any other u-boot development forks being packaged in Debian and > how viable do you think this is?

I am not aware of other forks being packaged at the moment. I think it is useful because there are many users such as everyone currently using Glanzmann's repo, but also those running Ubuntu or Deepin. Ideally we'll be able to migrate to mainline u-boot at some point but I don't see that happening too soon. > > Is this targeting Trixie or Experimental? Trixie, because that way it will be available for users of the Debian based Asahi ports at some point. Installing the packaged binaries in the boot path requires manual intervention at the moment so the danger of breakage pretty low. > > Is there any particular reason you're targeting u-boot?

Both of them are relatively straightforward to package, have tagged releases and are useful even without having a working kernel. Also: we need to start somewhere. I don't currenly have a good answer for the linux-asahi kernel. Ultimately I would of course like to have a working kernel available. > > Do you have contact with upstream about this?

I am a maintainer one of one of the community ports where we already ship a packaged version of the asahi u-boot and so far that has not been a problem. The problems you mention were caused by distributions packaging and publishing versions of the upstream software that was neither tagged nor released for the official Asahi distribution and had known bugs. I don't think there is a problem here if we stick to upstream releases and act responsibly, but I wouldn't mind asking for an official blessing from the upstream maintainers if you prefer that. > > How does this effort compare against Thomas Glanzmann effort[1]? > Do you plan to provide a migration path (and why would users migrate > over to debian-bananas effort instead of Glansmanns effort)? > > (IMHO while Glanzmanns effort is not my preferable packaging style, it > provides a very good stop gap solution until everything has been > mainlined into u-boot, linux, mesa which in turn then and only then > makes it ready for proper Debian packaging.

I have discussed my plan to package m1n1 and u-boot with Thomas Glanzmann before I sent this mail to make sure it doesn't interfere with his work or break existing installations. The idea is that once we have them in the official archive, he and others can switch to using those versions instead of maintaining their own. Glanzmann's repo is still useful because it provides a convenient installer and all the other packages we don't package for now such as the asahi kernel and mesa. > > Something that I think is missing in Glanzmanns effort is providing > https://github.com/AsahiLinux/alsa-ucm-conf-asahi which is needed > for audio out on the mic/headphone jack.

That certainly is the main reason.

We only just registered the team so this is all work in progress. The plan is to have an official team for anything Apple Silicon related. You can join us in #debian-bananas if you are interested!
