Well? Any regular OTW dwellers?

I'm running Gentoo on my RPi 2B and use it as a NTP server with a GPS receiver, a task for which even the RPi is overpowered

Since this is a very, vary basic system most packages are compiled in a tmpfs, just a few (binutils and gcc) are compiled on the sdcard because of their size.

flysideways,

I do 64 bit Gentoo on Raspberry Pi 3 but I don't follow OTW unless someone posts in the report thread.

I too have an NTP timeserver on one of the first 10,000 Pi Bs with 256MB RAM.
I never got around to doing it in Gentoo, so its still running the downloaded modified Debian.

First I should say, I have one pi of each. some more than others. but at least one of each. 1 a and b. 2 2a and 2b (of each). 2 3a and 3 3b. and one zero.

I ran various versions of gentoo on the raspberry pi over the years. Which at some point lost due to one reason or another. either wanted to do something fast and the thing I wanted wasn't compiled in, so had to reinstall a quick raspbian. kept a backup, but who wants to restart from backup. so restarted it from scratch.

Which is what i've been working for a few weeks on. I made a 32 bit image for armv7 and upwords. it will not work on the platforms that have only one core, but will work on any of the multicore ones. it has the unstable branch, so gcc 8.2.0. clang and llvm. kodi. omxplayer. the raspbian userland. lxde|xfce|openbox. it also includes static versions of qemu-system-arm. which means you can chroot in it as if it was amd64. crossdev and x64 toolchain as I am entertaining the idea of a cluster of 8 pi's to compile distcc code for x64, because they are low powered. dosbox, wine ofc. the ps2 emulator. I never got to try it, but I can't wait to actually try it. basically all I have seen and liked in others oses, i tried to make with gentoo. for a pi. I had to settle for armv7 because armv6j can't do most of the stuff, and aarch64 can't do it either because it can't use the mmal. whatever. maybe I'll figure out how to run kodi in aarch64, but atm, since that is not easily doable, i did armv7.

and I'm thinking to provide this for everybody. if they choose to try it.

Moved from Gentoo Chat to Gentoo on ARM.

Its one of these now.

Kodi on 64 bit Pi3 B doesn't quite work without frame dropping.
My test sequence is the opening of the Good the Bad and the Ugly, where the dog walks across a long shot from right to lef..

The Pi 3B+, which is 200MHz faster, if you can keep it cool, is just about good enough. That's without mmal too.
mmal is coming to 64 bit Pi real soon now.

axl,

See Sakaki's Bootable 64-bit RPi3 Gentoo image (OpenRC/Xfce/VC4) UPDATED and help yourself from my arm64 binhost too.

I have that installed on my usb2sata adaptor. I have a 120 GB ssd connected to one of my raspberry pi 3b+, booting from usb, with pinn, and with fedora, kali, raspbian, libreelec, gentoo from sakaki, my gentoo, etc. that's what I'm saying.

flysideways,

I recall the kernel alone taking several hours to download over a serial modem. :)
I didn't start Gentoo until a few months after I got 512k broadband in 2002.

My original 256MB ARMv6 Pi is running a Gentoo CUPS server to share two USB printers over the network. And I squeezed it onto an old 1GB sdcard.

Hello,

Coming to this thread a little late as I have been busy with other stuff recently, but as is covered (in painful detail ^-^) in the sticky NeddySeagoon linked to above, I currently maintain an (unofficial!) bootable arm64 OpenRC Gentoo image for the RPi3 B/B+, available on GitHub here (also available on PINN, thanks to procount, where it is called "Gentoo64"). This has been through quite a few iterations now, but was built out originally on a system following the urtext of Neddy's excellent tutorial.

It comes bundled with a reasonable set of pre-built software (libreoffice, firefox quantum, chromium, kodi, vlc etc), runs Xfce4 with some VC4 acceleration (vc4-{f,}kms-v3d) and is backed by a weekly-autobuild binhost (here), to lessen the maintenance burden. NeddySeagoon also maintains his own binhost (here) which often has more cutting-edge ebuilds available.

The image uses an overlay (here) which provides a number of RPi3-specific services etc. This repo also provides a custom Gentoo profile (here ff) which is used to maintain the various arm64 USE flags, ACCEPT_KEYWORDS settings etc. required to get a clean build. A weekly[1] gated mirror of the main Gentoo tree is also provided (here), to ensure that users of the binhost get a high hit rate (as they will not 'see' version bumps to large packages like libreoffice until the build server has created a tbz2, I have at done at least a preliminary test of it, and the tbz2 has been pushed to the binhost).

There's also an associated wiki (here) with details about setting up distcc / crossdev, running a user-mode QEMU binfmt_misc chroot, etc. for those interested.

The project started as a way of sharing the system I wanted to run on an RPi3 myself, and thought would be useful to a few others, but has had a surprising level of take-up: over 15k downloads[2] and 250 GitHub stars to date. For many of those users, it appears to be their first experience of Gentoo, and indeed on a personal level, my hope for this project - and the reason I'm still maintaining it - is that it might just encourage some of them to try Gentoo on a PC as their "daily driver" as well ^-^

[1] With the occasional slightly longer pause, as now, when a new image release is in the final stages of prep.
[2] Across project versions; the actual 'distinct user count' will be significantly lower than this, of course.

PS: useful info about Gentoo on the RPi family may also be found on the raspberry pi forums, e.g. here.

Hi,
I'm using gentoo on my RPI 2b as a kodi mediacenter.
It's working like a charm.

If someone needs the ebuild for kodi on gentoo rpi, here's my overlay:

I've just installed Sakaki's RPi64 build on a Pi 3B and am building Gentoo (slowly) on an original Pi B too. I've got it running nicely on a Banana Pi also.

I've got a whole heap of other SBCs including more Pi's, Tinkerboard, some Orange Pi's, a Nano Pi, Odroid XU4...

I've got an idea to do a YouTube channel called about building and running Gentoo on everything I can so want to build Gentoo on all of these and review/benchmark them.

I have a RPI 1, first revision. It runs on NFS, and the system is build using a qemu chroot or crossdev on Intel machines.
