i read that most of the developers are on a 64 bit userland.

i managed to get a running system on my apple g5 with the 64 bit userland. i got xorg-x11 running too, but saw that a lot of work is still going on to get all of the apps running.

i also read for a desktop, that the 32 bit userland should be more than sufficient.

any thoughts here? why you made your choice as you did.

I used to run ppc64 on my G5 but found that aot of packages just weren't available. I am now running a ppc64 32bit userland profile. It seems a little faster and many more programs are available for it.


Unless you have like 8 gigs of ram I suggest a 32bit userland.

i have 3gb of ram. i think you can enable the 2gb+ support in the kernel for the high mem support right? or am i thinking about the x86 kernels.

32bit! More packages out there. It used to be (or still is?) the same sort of situation for the x86 vs. amd64 world. If you have an amd64 you can just run a 32bit operating system. But the G5 chips need a 64bit kernel, I think, in our case.

I would appreciate if there were more people out there who use 64bit userland and do some package testing :) i.e. if you want to use a package that is not keyworded for ppc64 test it and report it. although 64 bit userland is slower in many cases it is my favorite userland 8)

One mayor thing missing on ppc64 bit userland is still firefox, but it will be available in the next few weeks.

And you don't need 64bit userland to support 8gigs of ram either (unless you want that *one* application can use all of those gigs). only a 64bit kernel is required.

i just rebuilt it with 32 bit userland, but i'll switch back over in a bit.

if there are any particular apps that you think need testing, etc, please let me know.

maybe we can start another thread just on that.

Don't know why we have to wait for a few weeks while firefox-2.0 has been running stably for about a week on my ppc64 with 64-bit userland.
