Last times the g-i was tested on PPC, it turned tout that

Known good : radeonfb, vesafb (or whatever x86 uses).

vesafb is not built on powerpc, and the laptop we had in extremadura used a
radeon chipset, altough of the R300 variety.

isn't "fbonly" the PPC equivalent to "vesafb" on i386?

That is offb, and no, it is totally different :) Most drivers are builtin the
kernel though, so therei s really no need for offb, except for real old

ah, ok!

I know claudio ciccani worked a lot on DFB's Radeon driver recently, so things may have been fixed in DFB 0.9.25.

Currently in unstable ?

yes, the same version we're using in the g-i

Known bad : atyfb, nvidiafb

when acceleration was enabled.
But that was with GTKDFB 2.0.9 and DFB 0.9.22, while now we have DFB 0.9.25 and GTK 2.8.20 and many bugs got fixed.

And it will be better with gtk 2.10.x even, right ?

On i386 this proved to be true, but i cannot speak for other archs as i never experimented anything personally.

Ok. Let me think to get you an efika board once the developper program is

ok, BTW i'm in contact with Gentoo PPC porter, maybe i could ask him if he can let me use a PPC board to debug the g-i

This is the most serious bug affecting g-i on PPC, and i wasn't able to fix it because i have no PPC HW.

Yes, i will. Need to build a netboot g-i image and will test that on my
pegasos with the radon 9250 board.

If you experience crashes, you may want to run the d-i in a chroot cage, like explained in this [1] wiki page.

Ok, thanks.

Sven, do you think can give the PPC g-i a try? i will help you on debugging it as much as i can.

Indeed, that is my intentions, a first test today, and more over the week-end.

thanks! Having the g-i avalable for PPCs too would be really nice!

Indeed. As said, i would have done this earlier, but well, the context was not
favourable to this kind of things, let's say.

I really hope we'll be able to deliver a working g-i to PPC users too..
