dmesg output (only the lines that mentioned pci) :

apus_pci: apus_setup_pci_ptrs: Phase5 B/CVisionPPC PCI bridge detected.
APUS: BATs=1, BUS=67MHz, RAM=70ns, PCI bridge=1

apus_pci.c line 179 iirc :

What the hell is this?
CVS messed up ?

PCI still doesn't work btw...

I disabled loadable module support and configured everything of parallel port and printer to be

BTW a good way to get a working 2.4 config from a 2.2 one is to copy the
.config file and then do 'make oldconfig'. That will keep your config as =
much
as possible and only ask you about new or changed options.

SourceForge hosts thousands of projects. You don't expect anyone to know =
them
all, do you? :)

As for if you can compile them, most stuff for 'Linux' should build on AP=
US.
In particular, all architectures of Linux/PPC are even binary compatible.
Unfortunately though, a lot of people think 'Linux =3D=3D i386' and that'=
s how
they write code. Which then often doesn't work or even build on other
architectures.

There is no easy way. Search SourceForge for interesting projects and fin=
d out
if they are already packaged (most likely in Debian ;) and if not, you'll
probably have to find out yourself if they build and work.

My first thought here was that you may have missed ext2 support, but some=

the ext2 functions are there so I don't know... Have you done make dep be=

make vmlinux?

You probably have configured a parallel driver as a module but it should =

the kernel or vice versa.

How to compile 2.4 sources?

[T. <Ren...@gm...>]

Hello everybody!

I tried to compile the sources from sourceforge/apus cvs 2.3 dir with
different options set, but it won't work at all! I got the latest error
output and will attach it. Unfortunately I forgot my config file, if I
should post it too, please say so. I (in my opinion) disabled all
uneccessary options. The errors are from the scsi-part I presume. I
enabled GVP, Fastlane and CyberstormMKIII option.

By the way: Where can I get all module names stored in sourceforge CVSs?
If I browse the tree using a Webbrowser there are only a few dirs shown,
inclluding 2.2 and 2.3 (within APUS). Is this 2.3 the latest kernel
(2.4)? When I tried to connect to XFree CVS anonymously the CVS server
rejected connection. How can I get the latest XFree86 then? And what
else CVS repositories are at sourceforge containing which modules and
can I use/compile them using APUS? There are no informations given at
sourceforge page (at least not for a normal browsing/searching human
being)! How will one get an summaray about all CVS modules available
usable with APUS?

Many thanx in advance!

As an example, you can take a look at all `gg2' stuff in
arch/ppc/kernel/chrp_pci.c. It's known to work fine on my PPC box.

Basically you need to know
  - how to access PCI config space (old code knew)
  - wehere PCI memory and I/O space are located, to set up the bus resources.

And enable all DEBUG code in drivers/pci/*.c and arch/ppc/kernel/pci.c.

Good luck!

The PPC PCI code has changed heavily and we are probably missing some kin=

initialization. Like setting up bus resources, etc.

I'm not sure how much I can help with the coding.
If someone can point me in the right direction, and give me some info on
the implementation of the pci code, I could have a look, but I doubt
I'll be able to fix anything. Think it may be a bit lowlevel for me...

But If someone writes any patches, I'll be happy to test it !

Erm, ...

what is the content of /proc/pci, i think it is empty.

Notice that pci code seems to be broken on 2.4 kernels right now (well for
apus-pci anyway, not the generic pci code naturally).

Help is wanted to fix this, you volunteer ?

Erm, ...

We should maybe fix PCI in the 2.4 kernel any idea ofwhat the problem is ?

(well i guess there were lot's of changes in the 2.4 pci code with regard to
the 2.2 one, or the time Michel wrote the PCI support).

There will nextly be a 4.0.2 bugfix succesor, which should fix the bugs in XF
4.0.2, and should be packaged almost immediately by branden i think, which
should fix the use of non-PCI (or broken PCI) 2.4 kernels.

But best would be if someone could test current cvs XF4 on a broken PCI
kernel, or maybe even better the XF4 from the 4.0.2 branch.

Maybe i should setup a cross compiler on my box here at work and compile one
for people to test. Any experience with cross compiling X ?

PCI in 2.4.1

Hi,

I have just tried a 2.4.1 kernel with PCI support enabled.

When I run dmesg, it has only three lines that mentions PCI, so it doesn't
look like the PCI code does much. I was expecting a lot more when debug was
enabled:

apus_pci: apus_setup_pci_ptrs: Phase5 B/CVisionPPC PCI bridge detected.

APUS: BATs=1, BUS=67MHz, RAM=70ns, PCI bridge=1

Like the fix for the parallel driver? AFAIK, the fix was done in the generic
code, not in the amiga specific parport_amiga. But as I have no revision
history of that time, I can't have a look.

Maybe, but this topic didn't start from a backport but from new developme=

done in the 2.2 tree. Bug fixes are important, backports should be option=
