I'll be receiving my Parallella in a couple of days. Since I've been using Gentoo on all my machines for the last two years I was wondering if anyone has already tried to run it on the Parallella.

If not, I'll be posting any relevant updates here and on the Parallella forums.

Also, any tips that you may have would be helpfull.

Looks interesting :D

Looking forward to updates - might consider replacing my Raspberry Pi ;)

Lots of unmasking to do on the arm-platform though :(

I received it today, but I found out I lost all my microSD cards. So I'll have to wait till a new one arrives as well.

From first looks it looks nice though, nicely the size of a credit card.

Please post about your experience with parallella, I like the idea and i'm really curious if it's half as good as they say :)

I currently have Gentoo fully running on the parallella and everything runs ok.

The basic steps that I took to get it running:

  • Use the normal kernel images (eventually I changed some settings and recompiled it)
  • Download de armv7a-hardfloat stage3 tarball from one of the servers.
  • Copy that to the partition on my sdcard where ubuntu was on
  • Set up fstab
  • Setting up a crosscompiler on my main pc (used for distcc and recompiling the kernel with extra features)
  • VIDEO_CARDS="fbdev" in make.conf (needed for xorg to work)
  • Update and install lots of applications, which it is still working on.
  • ACCEPT_KEYWORDS="arm ~arm" in make.conf (To get testing versions of applications, since almost nothing has been tested enough on arm to be marked as stable by gentoo)



If you want to try do this yourself you should read the wiki for the Raspberry Pi and forum posts for that one as well. Since most of the problems you'll run into are covered there as well.

I had quite some trouble with crosscompiling, distcc seems to work however. I did however find out that my class 10 microsd is quite slow and I'll try to run my system (except the kernel) of a harddisk in a couple of days. It is especially slow when trying to compile and install programs since that involves reading and writing of lots of small files, which it is not very good at.

As for the kernel config changes, I think I'll push some of them back to the official git repo. Since one was needed to get my usb hub to recognize more than one device, which seems like a feature that would be nice in the default kernel.

So, how does it perform? Do you see 64 cores in /proc/cpuinfo? Do you get a huge 64x speedup when compiling world with 64 jobs?

This is redundant. Accepting unstable sources automatically accepts the stable ones as well.
