David du Colombier has kept up a comprehensive list of patches at 9legacy ( https://www.9legacy.org/patch.html); it's the best place to start.
Although patches can still be submitted to Labs' sources, the last time any kernels in that repository were updated was in 2014. Fortunately there are other maintained distributions[*] I'm not sure how patches made in one distribution make their way into other distributions. I don't know how long this form of patches against Labs' frozen version would be possible. As patches pile on, a set of deltas need to be kept going back to the Labs' sources. It begs the question of how do we organize a community maintained repository? [*] list of Plan 9 distro's I'm aware of: 9legacy distro: maintained by David du Colombier 9front distro: kept up by ɔᴉuɐd lǝuɹǝʞ and 9 people's front people 9atom distro: kept up by Erik Quanstrom 9pi (bcm) kernel: maintained by Richard Miller; sources are in contrib area on Labs' sources On Mon, Feb 20, 2017 at 4:47 PM Steve Simon <st...@quintile.net> wrote: > sadly there doesn't seem to be a way to add users to the labs sources > server, > unless somone knows different. > > I think the best thing would be to post diffs to this mailing list. > > I have some small changes to APE I have been meaning to post, nothing > substantial > mut enough to make porting some tools easier. > > -Steve > >
