Bootable 64-bit RPi3 Gentoo image (OpenRC/Xfce/VC4) UPDATED

Has anyone gotten any Bluetooth headsets/speakers to work?
I tried using the bt applet that's on Sakakis image. I was unable to diagnose the problem since the error message only tells "unsupported protocol". I don't know if it means that I try to send invalid PCM or if I try to use wrong BT protocol or if santa isn't comming next x-mas. :( I think I got pairing working. They seem to connect.

But to be honest; bluetooth has always been pita to use in any platform. Especially bluetooth audio devices. *sigh*

Zucca,

"Work" would be stretching it but I have had audio out of bluetooth speakers using bluealsa (its not in the tree), since I don't use pulseaudio.
The bluetooth is < 1Mbit/sec.

Sound kept droppind out.

@roylongbottom:

thanks for your guidance!
I'll try that out once back from vacation - but would there be a way to benchmark/check the crypto extensions (do they work under aarch 32 as they are supposed to)?)

I love to be a gentoo user, not only because it's a great system but mostly to the people like you all here in this thread

Zucca,

Or try the Pi serial link faster ... that would be my first thing.

I'm not sure if bluetooth audio devices support compression on the the bluetooth link.

Hello,

I've just posted a v1.1.3 bugfix release of my bootable 64-bit Gentoo image for the RPi3 on GitHub (here).

Existing users of the v1.1.{0,1,2} image can simply run genup (as root) to effect the upgrade (or wait for the weekly autoupdate to take care of this on your behalf); those looking to migrate from a v1.0.{0,1,2} image should follow the instructions here (the final genup step of which will now land you at v1.1.3, instead of v1.1.0).

A changelog from prior release image may be viewed here, but in summary:

Added the top-level packages media-tv/kodi-17.4_rc1 (a FOSS media-player / entertainment hub) and media-sound/clementine-1.3.1-r6 (a FOSS music player and library organizer);
Added dev-java/icedtea-3.5.1 (as the default system VM); app-office/libreoffice is now built with the java USE flag enabled (for Base);
Added x11-misc/twofing-0.1.2-r2, which provides two-finger gesture support (emulated right-click, scrolling, pinch zoom and rotate) when using the official 7" touchscreen. It is active by default (but has no effect on systems without a touchscreen attached);
Added app-accessibility/onboard-1.4.1, an onscreen keyboard, again primarily for touchscreen users;
Prevented NetworkManager from changing the hostname if one is offered to the machine via DHCP, as this was causing the .Xauthority file for the automatically logged-in session to become invalid in some cases;
Added a pseudo-ebuild xfce-extra/xfce4-mixer-4.99.0-r1, to allow seamless replacement of xfce-extra/xfce4-mixer, which has been masked, due to vulnerabilities (bug 628424). The new version installs media-sound/volumeicon instead;
Various minor ebuild tidy-ups;
All packages brought up-to-date against the Gentoo tree, as of 15 September 2017.

Upgrading users (who want them) will need to emerge kodi and clementine, as these are not pulled in by default (as always, the necessary packages are on the isshoni.org binhost, so this shouldn't take long).

The Pi-Top variant image has also been updated to v1.1.3.

As always, any problems feel free to contact me by email (sakaki@deciban.com), or post in this thread, for support.

That's probably going to about do it for new packages for now (the image having hit 1GiB compressed); when I get a chance the next push will be to PR the various changes from the image's custom profile.

The latest version v1.1.3 of Sakaki's Gentoo64 image for the RPi3 and Gentoo64pt (for the PiTop) are now installable via the PINN multi-boot manager.

What is PINN?
PINN is a fork of the RaspberryPi NOOBS installer that includes some additional advanced features.
It allows easy installation of many different operating systems using a FAT32 formatted SD card, so it is easy to use for beginners coming from Windows, or more advanced users alike.
It can install several operating systems to the same SD card or USB drive and includes a boot manager to select which OS will be executed on boot.
Operating systems can be downloaded from the internet, or for offline use they can be installed from the SD card or a separate USB stick.

EDIT: For more details or queries related to PINN, please see my separate post here-> PINN multi-boot manager supports Gentoo64 on RPi3

Many thanks to Sakaki for her support in helping me convert Gentoo64 to the PINN environment.

Interestingly, the Raspberry Pi 2 is now shipping with a 64-bit SoC, as of v1.2. From the RS Components product page:

Sakaki,

I owe you a <insert_refreshment>. For some time I have not been able to build and run a glibc newer than 24-r4 and lots of things require at least glibc-2.25 as it has some new symbols.
Symptoms include unable to reboot, unable to connect to signal handlers 3, 10 and 15 and crashing emerge when it validates the manifests.

I gave up and used your glibc-2.25-r5 from your binhost. That just worked. Thank you.

Sakaki,

Thank you. I'll try that. I do indeed use distcc and distcc-pump and take care that I have identical gcc versions.

There is somethind odd, your tarball is quite a bit bigger than mine.

For those interested in disabling the Intel Management Engine on their PC, I have just posted an addendum about this to my EFI Install Guide, here.

An RPi3 (running gentoo-on-rpi3-64bit) is used as the external BIOS flashing tool (photos and wiring pinouts are provided in the guide).

The tutorial makes use of the wiringpi ebuild (already in my rpi3 repo) and the me_cleaner and coreboot-utils ebuilds (which I've added to the sakaki-tools repo).

me_cleaner itself was written by Nicola Corna and may be reviewed on GitHub here.

The process works with most standard BIOSes; coreboot per se is not required (only some of its utilities).

Have fun and please don't brick your box ^-^

Please note that this Friday's arm64 autobuild (which included libreoffice-5.4.2.2 etc) will be the last until the first week of November, due to some planned updates to the supporting distcc build infrastruture.
The existing packages on isshoni.org will still be available as normal during this time, as will the gated rsync mirror (it's just that updates will be on hold).
Apologies for any inconvenience caused ><

Sakaki,

Libreoffice now needs dev-perl/X11-Protocol which is not yet keyworded ~arm64.
My build has just finished.

The arm64 weekly autobuild is now up and running again, and an update has just been pushed to isshoni.org.
Any problems, please let me know.

Is it possible to do gentoo-on-rpi3-64bit kernel config and make directly on PI3B?
By numbers of reasons I want to do kernel make in PI64B directly, without using a crosscompile.

I was trying to do this as follow (SSH on PI64!!):

1) From gento wiki: Fetch the Raspberry Pi Kernel:
in /usr/src/local: git clone https://github.com/raspberrypi/linux

Than I need existing kernel .config file. I was found some in https://github.com/sakaki-/bcmrpi3-kernel/blob/master/config
2) wget this config file https://github.com/sakaki-/bcmrpi3-kernel/blob/master/config to the /usr/src/local and rename it from config to .config. Permissions also was checked by using mc.

Than I was made some little modifications by adding some USB devices support, just to check is it working:
3) make menuconfig

Now the kernel make was initiated:
4) make && make modules_install

After this, the new kernel was taken from .. /arch/arm64/boot and copied into /boot. The kernel file also was renamed to kernel8.img (I hope I'm not wrong with the name as it was done a few hours ago)
Than the PI64 was restarted and it was die (won't boot).

Maybe some wiki exist? I cant find it and I am not a skilled gentoo user to convert crossdef manual https://github.com/sakaki-/gentoo-on-rpi3-64bit/wiki/Build-an-RPi3-64bit-Kernel-on-your-crossdev-PC to implement it directly on PI64.

Thank you.

Hi orion777,

yes, it should be entirely possible to build a kernel locally on your RPi3, when booted into a 64-bit OS.

I would recommend initially you try to build a 4.10.y kernel and use bcmrpi3_defconfig, and not change anything via make menuconfig until you get something working.

For example (assuming your /boot is mounted, and you are booted into the gentoo-on-rpi3-64bit image to begin with), you could do:

orion777 · Posted: Fri Nov 10, 2017 6:04 pm Post subject:

I was downloading 1.1.3 image today and was burning it today by using etcher. However, I was surprised that I cant install MC and etc as everything becomes hard masked (red color). However, some packages must be green or even yellow, for example this https://packages.gentoo.org/packages/sys-apps/usb_modeswitch
So I will try to solve this problem at first and than I will try to make kernel as it was specified in Your previous post.

orion777,

arm64 is not listed there as its an experimental architecture. arm on that page is 32 bit arm.
Sakakis image is 64 bit.

Lots of things work in arm64 but are not tested. Feel free to join in the keywording fun.

e.g.

Thank you for the explanation!
Also I want to say that initially I forgot to run emerge --update on the just burned rpi64 1.1.3 image. I try to run --update and now more packages are available.

So now I will continue with kernel make at Monday; also thanks for arm and arm64 explanation - I will try it if the kernel make will be successful.

orion777 · Posted: Mon Nov 13, 2017 2:36 pm Post subject:

I understand that the question is stupid, but.. Does the kernel make stays active if it was launched from SSH and SSH session is closed? Or I have to keep SSH Session live until end of the process? Or I must use "screen" to safely close ssh session to keep kennel make running?
