Hi!
I'm looking for suggestions and comments on running Linux on PPC with the
intention of making an audio box. I'm intersted in suggestions for distros and
kernels, etc. I've got a Powerbook G4 17 that I'm dual booting with OSX and
Yellowdog, but I'm looking for something better.
Thanks!
Matt

Hi Matt,
I don't know any distro with a good kernel for audio, so my advice is
to build your own kernel. Personally I run Debian, but I liked Yellowdog
too when I used that.
Maybe all you need to do is build your own kernel and stay with Yellowdog.
Are you seeing any specific problems?
The graphics driver can cause latency problems without the right kernel
configuration, or kernel patches. This used to bite me (Radeon Mobility M7).
As for outboard: try to get stuff that is big-endian too. I've had to get or
make patches to deal with endian-ness after getting a litte-endian Edirol
UA-25. Those are not all official yet.

Debian runs lovely on an Apple Mac and if brave enough running sid
you'll have decently recent enough kernels and audio apps available
with no need for compiling.

As far as "any Linux is Linux" Yellowdog will be ok too. Also Ubuntu
which is Debian based and there are Ubuntu gurus hanging out this
mailing list. ;)

Yes. Also it looks like regarding latency kernels for x86 are better
tuned than those for ppc but this could be only a personal feeling.
As for outboard: try to get stuff that is big-endian too. I've had to get or
make patches to deal with endian-ness after getting a litte-endian Edirol

Not sure what you want to say here, so I guess its "thanks for the good
work!!!" :) I'm hoping the jackd patch will be included soon, as it seems
Paul is gearing up for LAC...

Well, we ppc kernel users would love to help testing...

Yes, I meant "never heard about that" but also "thanks for the good
work".
Have I told you lately that "thanks for the good work"? :)

I had to compile my own kernel with Ingo Molnar's patches and also
patch libpam-modules, but that didn't take me more than one morning.

whats wrong with yellowdog? anyways if you want to switch to Debian or Gentoo you can do
it without a reinstall (old binaries may be overwritten, but conf files will be ok). for
debian use debootstrap, for gentoo just untar a portage snapshot to /usr and start
emerging :)
a buddy recently gave up on installing debian or gentoo and went with yellowdog, due to
the finickynness of yaboot/miboot/quik/bootX and the patch partitions, miniature boot
partitions etc... so a 'live upgrade' to one of the above distro is what i'd
recommend..
