controlfb problem (on XFree86-4.0.1 off the penguinppc.org development tree)

Following up on message
http://lists.linuxppc.org/listarcs/linuxppc-user/200011/msg00346.html ,

I had a look through the linuxppc-dev mailing list, and found a few
patches to controlfb. I collected a few and made them fit in (from
messages in September).

XFree86-4.0.1 base: xfree86-pmac tree off penguinppc (today) on top of
stock 4.0.1 .

the result is that I get Xwin (yay!), if only in 15bpp (no big problem)
-- I get various error messages if I mod the XF86Config to pick up a
smaller screen area and nigher depth. (Maybe the problem is that an
1152x870 virtual framebuffer is always allocated?). In 8bpp, I get a
very wrong picture (too green, two images side by side on top half
...).

Anyway, enclosed the patches that - at least - made me see Xwin, on
2.2.18pre17-ben1 kernel straight off penguinppc.

Cheers

    Jens

I knew I was setting myself up for grief by getting the original
sources ;-)

Actually, I did roll this patch into my modifications. Could it be that
the development tree on penguinppc.org doesn't have these patches at
the moment?

Cheers

That could be; I never got any positive feedback of any patch that fixes
this problem getting close enough to official XFree to be swallowed ;-)

The patch I'm using isn't clean enough for that... and it might even not
work for all resolutions/depths; never tried...

Cheers

AFAICS everything except the very last chunk (is it important?) of your patch
has been integrated in one form or another into XFree86 CVS as a patch of mine
(the one I asked you to test, Michel) was accepted. Have you looked at the
XFree86 CVS lately?

Hi all,

On  22 Nov, this message from Michel Dänzer echoed through cyberspace:

No; I'm running XF precompiled from Franz's site, and the test modules
you asked about some time ago were binary incompatible to that XF
version. A long time ago I had an XF4 source tree in a 'compilable'
state; but that was 4.0. I then tried to patch it to 4.0.1, and failed
miserably ;-) It has remained in the same state since then...

Anyway, these patches getting integrated is good news. But I think right
now I'll patiently wait for RPMs rather than compile myself :-)

Cheers

Michel
