2.2.12 and USB on a B&W G3

2.2.12 and USB on a B&W G3

[Otto Moerbeek]

Hi,

I recently tried to compile the 2.2.12 tree, and it boots fine on my B&W
G3 (rev2, no scsi) IF I disable the USB driver. If I enable the USB
driver a kernel panic occurs, with a stack trace that leads to one of
the USB interrupt handlers.

It looks like some USB work that Paul Mackerras did is not included in
the 2.2.12 tree. Is someone (Paul?) working on merging these patches
into 2.2.12?

If not, I can give it a try...

Is there an "offfical" opinion if vanilla 2.2.12 should work on B&W
G3's? Where should I be looking to find this info?

Regards, Otto

I sent Alan a patch to update the USB support in 2.2.11 (for inclusion
in 2.2.12).  Apparently Linus gave it the thumbs down because the USB
stuff is still under very active development and he (Linus) didn't
want to be receiving patches against two different source bases, or
something like that.  Oh well. :-(

The USB stuff in vanilla 2.2.12 is so old that I would be *extremely*
surprised if it worked.

I would like to get these USB patches, so I can try to run my USB
devices on 2.2.12. Are they available somewhere?

Apart from the USB stuff, should the rest of 2.2.12 work on a B&W G3?
IOW have the other patches reached the 2.2.12 tree or should I expect
some more problems?

The easiest thing, from my point of view at least, is for you to get
my current 2.2 tree by anonymous rsync from
samba.anu.edu.au::linux-pmac-stable.  I could make a patch if you need
it.

2.2.12 is relatively up-to-date w.r.t. the PPC port.  I have heard
though that vger-current doesn't work on B&W G3s, so possibly vanilla
2.2.12 won't either.  I heard recently that my linux-pmac-stable tree
does, though.

Regards,
Paul.
