Arch Linux 64bit on Raspberry Pi 3

Wed Sep 13, 2017 2:40 pm

Hello guys
I want to ask
I want to install the linux arm arch in raspberry pi 3
but I'm confused to choose between 32bit or 64bit
on the arch linux arm website, in section aarch64 there is a description like this:
"Aarch64 Installation
This provides an installation using the mainline kernel and U-Boot." There is no support for the vendor-provided libraries, extensions, or related software. "Some of the hardware on the board may not work, or it may perform poorly."
is the statement true?
that's what makes me hesitate to try the 64bit version
so I have to choose which one?
does the application support better on 32bit?
64bit version can also run 32bit application right?
I see in the package list, 64bit applications are not complete compared to 32bit
sorry for i ask a lot :oops:

The RPF(T) recommend Raspbian, which is 32bit. Generally there are some minor performance improvement on 64, but nothing huge. But if you really want Arch, I'd go with 32bit, since we know all the Raspberry specific stuff works in 32bit and we know there are some issues with running them under 64bit.

Basically go with the 32-bit version if you want wifi and bluetooth to work.

Hi,

A bit late to the this thread, but I'm new to Raspberry Pi. :)

If you want 64-bit, then I would recommend reading here:
https://forums.gentoo.org/viewtopic-t-1058530.html

There is a link to the GitHub page that has a ton more information. I looks pretty stable. They are using the 4.10 kernel which has the audio fixes. They provide a downloadable image, so you don't need Gentoo as a main PC, but if you have a Linux PC of any distro, then you can set a cross development environment with distcc so you can install new things on your RPi, you would need to change the instructions on setting up a distcc server in GitHub wiki to your Linux distro.

I'm going to be trying this out to see the performance difference. I have no idea what to expect with this. :D

Cheers

Can you provide a link to a complete image? At the page you've linked there are dozens of links, which isn't helpful for a Gentoo-beginner?
Forgot my post & thanks for providing this! (Just need a little bit scroll down!)

Thank you, FM_81
A: What does the command 'cat /dev/urandom', can you tell me please?
B: Yeah, that's very simple: It feeds your cat with radioactive material!

Sorry. Didn't see your post sooner. The main GitHub page: https://github.com/sakaki-/gentoo-on-rpi3-64bit

I've been trying it out now for several days. There is a bit of a learning curve with Gentoo, like if you want to remove XFCE4 and install something like LXQT, or other, you need to unmask certain things or change use flags. You definitely need a distcc server to help with the compiling.

I'm able to run certain programs only compatible with 64 bit architectures now, which is why I went with a RPi3. It also boots really quickly and is surprisingly stable. I hadn't had a single crash yet and it's been running nonstop for days. However, if Raspbian switched to being 64 bit, I might consider switching to it. However, use flags are very powerful, so I'm torn as to what I would do. Being compiled only for the new architecture to enable all the opcodes and features of the CPU is what makes the Gentoo based distro faster than the 32 bit version of Raspbian. :) I imagine Raspian would gain the same benefits.

The RPi was designed for tinkering and the Gentoo based OS really fulfills that!

This gentoo64 build from Sakaki is also easily installable via PINN.
Sakaki helped me convert it.
