PowerPC/AmigaOne? When did they ever support PowerPC/AmigaOne? I've never seen an official kernel build in the past 15 years that supported PowerPC/AmigaOne out of the box so I don't know that means.

Do they mean removing support for configuring it in a custom kernel? In that case PowerPC/AmigaOne is rather obsolete as there has been PowerPC/SamXXX, PowerPC/AmigaOne X1000 and PowerPC/AmigaOne X5000 in the meantime. All completely different PowerPC/AmigaOne platforms. Also what about PowerPC/Pegasos that was directly supported in PPC distros?

To be fair running Linux on a PowerPC/AmigaOne platform these days is too dog slow. You can't do much with it. Even just on a simple desktop it's not good. A sub 1Ghz CPU and no graphics acceleration is just too slow for even basic work. It works but it isn't pretty to deal with lag. The only thing in its favour is the kernel can boot real fast on an XE and would be wicked fast on an SSD I imagine.

Code to boot Linux on a first-gen AmigaOne is in the official Linux source code since kernel v2.6.30 IIRC. Distribution support is naturally a different thing. In this case you're right: no GNU/Linux distribution ever provided kernel images for the first-gen AmigaOne machines.

Big problem in this case was that interest in PowerPC was declining due to Apples shift to x86 and Debian lost its PowerPC maintainer back then. So bringing AmigaOne platform support into Debian wasn't really possible at that time. My hope was to change that now that the Debian PowerPC Port again has a proper maintainer and new distributions like Void PPC are specifically targeting PowerPC. But hope dies last...

They're talking about completely removing support for building a kernel that can run on first-gen AmigaOnes.

I agree that it is dog slow and the missing graphics acceleration is a pain in the ass, but according to this also support for the m68k/amiga platform would have to be removed where even booting the bare Linux kernel takes at least 10 minutes. But okay, this platform has probably more Linux users than the first-gen AmigaOne.

BTW: is any of the other AmigaOne platforms officially supported by a Linux distribution (and no, I'm not talking about the support provided by AEON for Linux)?

I searched the kernel,org mailing list thread, and at this time there's really not any further information, except for this brief note:

I can also confirm that Pegasos2 users in the Amiga scene are running Linux (Debian) on these machines.

Yepp, some users over at a1k.org have installed Linux on their Pegasos2 machines. More important however is that the Debian PowerPC ports maintainer is still using powerpc/chrp machines to which the Pegasos2 belongs to.
