Linux 2.4.16 Bug (PPC)

Linux 2.4.16 Bug (PPC)

[war]

Bug still resides in 2.4.16 still, even after the PPC fixes that were
applied to 2.4.16-pre1.

If nobody cares about PPC updates, I guess I should put the box back on
the shelf.

The video driver (plat) is the framebuffer for a few macs, without it,
I cannot do anything.

Any plans to fix this?

//              default_vmode = nvram_read_byte(NV_VMODE);
//              default_cmode = nvram_read_byte(NV_CMODE);

Commenting the two undefined functions out in drivers/video/platinumfb.c
allows for a successful compile.
It also allows for the video driver to be brought up succesfully.

Now will this bug be fixed in 2.4.17 for PPC or should I just put my PPC
back on the shelf? :)

I think the PPC maintainers care about PPC fixes;
most likely they're even forwarding patches to
marcelo ;)

Looking at the MAINTAINERS file, it appears that PPC is missing a person
to look after it.  I suppose you need to produce a patch that fixes the
problem and submit it to the relevant people/mailing list for inclusion
in the kernel.

Not really: The PPC people have patches to do that. I'll probably get them
into 2.4.17-pre1.

Well, not for that driver in particular but Paul Mackerras is listed
under 'LINUX FOR POWERPC' and Ben Herrenschmidt for 'LINUX FOR POWER
MACINTOSH'.  The file itself lists a few names, but no email address
however..

Is that problem that it isn't apparent that PPC == PowerPC == POWERPC?

(Hmmm, I need to update that URL too.)

Didn't see this one reported before...

Is CONFIG_NVRAM on?

Is CONFIG_NVRAM built in to the kernel?

Gratuitous rudeness will usually get you an answer. :)

Have you reported this before, on this list or anywhere else?

The problem is that your config is slightly unusual in that you have
turned off CONFIG_NVRAM.  We can put some ifdefs in so that it
compiles without CONFIG_NVRAM.  For now, just turn on CONFIG_NVRAM.

Already learned how to fix this earlier, had to have nvram compiled in.
