It is indeed possible to use only the ~arm64 ::gentoo repo on a 64 bit Pi now but in one or two areas, particularly multimedia, it remains sub optimal.

Those pesky date based version numbers. I've read the 20201022 as 20200122 and thus thought it quite old and older than what is available in the genpi64 overlay. Guess I'll replace this package too. Pulseaudio still is an older version than in the overlay, so not sure if the upstream version contains all fixes. Guess I will keep it for now. But still, down to one package from the overlay, thanks! :)

Finally I successfully installed Gentoo on my pi4b, basically follow the "Raspberry Pi4 64 Bit Install" document and use sakaki's image as bootstrap for build new kernel. cheers.

I have done multiple installs following different paths.

Currently I am working on one using limited resources as would be expected for someone with a Pi but new to Gentoo. (right now it is updating from the lagging snapshot, 66 packages)

An overview:

Using the Raspberry Pi Imager to do the firmware update, per their instructions, for the USB mass storage boot.
Using the Raspberry Pi Imager to burn genpi64.img.xz
Following steps in the amd64 handbook, modified for the arm64, using steps from Neddy's RPI64 wiki entries and the Chroot wiki entry to build entirely from the Pi.
I have been through it once using git pulls for the needed parts and am doing it again trying out the Gentoo repository in place of git.

I have a bunch of notes and will post them up after I get them in a clear and concise form.

This is exciting. Someone with any desktop or laptop can use the Pi tools and genpi64 to get a first start into Gentoo on a Pi 4. It is a whole lot more than my Athlon 1200 was, and doesn't idle at 130 watts.

For the experienced, what all is really necessary to migrate from genpi to Gentoo if you're on a standard SD card install? Seems like you need to move some packages from ::genpi to ::gentoo, re-emerge, get your own kernel toolchain together, build, and go... does that about cover it?

Pretty much. Also a good idea to get distcc up and running if you have a computer that can assist.

If you want to reduce the pain marginally, you can also use https://packages.genpi64.com as a binpkg provider. It's not really ready for prime-time yet, but the packages which are there *should* work (as usual with this sort of thing, if it breaks, you get to keep the pieces).

Hi,

I don't know if people are aware here, but we are working on with some people on getting a Gentoo for Raspberry Pi going again, with help from Sakaki's work.
Help and ideas would be much appreciated, like what default packages to include, default kernel and things like that. Please see the Github issues for those.

Our binhost: https://packages.genpi64.com

Sakaki might appreciate her email being removed from the forked project, unless you have her approval.

It is in the Feedback Welcome! section at the bottom of the page.

I think it may help that to have an equivalent .img of Gentoo minimal install iso.

That was totally forgotten to remove, but now it has been removed.

There is stage3 already, so it would only need kernel and should be bootable.

Thank you for pointing that out. I've combed over most of the code once already, examining the output of
Code:
grep -R -i sakaki
, but it can't all by blindly removed as her copyright notices and authorship information needs to stay. I am unsurprised something got missed. If you spot anything else, please point it out.

I was just pointing out the email being in a section soliciting feedback, of course the copyright attribution must remain.
