Re: [patch, 2.6, ppc] some modular framebuffer support

Let's bring linux-fbdev in the loop, as they probably are the best
placed to comment.

Hi,

the following patch allows some accelerated framebuffers (aty128fb,
atyfb, radeonfb, and rivafb) and framebuffer console support itself to
be built as modules on ppc.  Tested on a Powerbook Pismo, works very
well including XFree86 and DRI.

The first hunk suppresses a warning only, not sure about it.

Jens, i am not sure of the wisdom of pursuing this way. I know that
modularizing stuff and even fbdev drivers is a good thing, but i also
know that you plan to use this to modularize most fbdevs out of the
debian powerpc kernel.

I wonder at the implications, since modular fbdevs are loaded well later
than non-modular ones, and we thus lose lots of early log messages,
which may be ok for us hackers with a serial console ready to catch
them, but may be a nightmare for general users of the debian powerpc
package, not to speak about us who will have to do the support job on
those.

linux-fbdev folk, what is your take on this, would it be possible to
somehow get a way to have earlier debug messages, or to bring the
loading of fbdev modules to an earlier point ? Benh, where you working
on something such ? I think i remember something about this mentioned.

Or maybe i am wrong, and using a modular fbdev on a not offb supporting
powerpc is just fine.

compiling radeonfb as a module works just fine for me in 2.6...
I don't see why you need a patch...

If you want it for early boot text messages, don't bother with modules.
You can't unload fbcon, so you're not gonna be able to unload the fb
driver either.
