load 2.4.x binary only module on 2.6

load 2.4.x binary only module on 2.6

[Marcel Lanz]

I have a binary only module for 2.4.x.
How much work is it to write a kind of wrapper to load an "old" module
on 2.6 ?

Unfeasible.

http://www.minion.de for a counter-example.  Of course, the NVidia
driver was already built with a wrapper for the 2.4 kernel, so doing a
2.6 version wasn't too bad.

It's really going to depend on which kernel interfaces the module actually
uses, and what the module is doing.

It may be there, and I may have a copy of it, but it won't install if 
I'm running 2.6.0-test9-mm2.

Huh?  I'm running -test9-mm2 with the minion stuff as I'm typing this.

Or are you talking about the general case if you have a wrapper for
a 2.4 kernel?  If so, then yes, you'll need to do some programming to
get the wrapper to do things the 2.6 way (which is what minion's patch
basically does, it changes the NVidia 2.4 wrapper code to the 2.6 schemes).

I've got minions 4496 here, so how did you make it work?  I had to 
revert to the kernel driver nv which doesn't do as much, but is 
easily 100000% more stable.

Got NVidia's tarball, did the --extract-only thing, applied
the Minion patch, 'cp Makefile.kbuild Makefile', reboot to the
-mm2 kernel, 'cd src/NVdia<mumble>/usr/src/nv && make'.

Actually, I've just had to do the 'make' for the last umpteen kernel
revs - the Makefile dates back to Aug 4, and Sep 5 I had to apply a
2-line fix to nv-linux.h.

Not sure if the nv driver could be more stable - the last time I was
able to tickle the NVidia code into crashing either XFree86 or the kernel
was back in the 2.5.6* time frame.

Very very easily done.  ctrl-alt-f2 to a shell.  It may, or may not 
work.  crtl-alt-f7 back to X=locked up "tighter than Ft Knox" 
computer, reset button or power button is all that works.

Odd.. That works fine for me as well (I often do that to go look and
see if exec-shield or ipfilters has tossed any odd messages).  I wonder
if it's because I'm using the vesafb framebuffer driver over there and you're
using something else? Or maybe the NVidia stuff happens to be stable for
the GeForce 440Go in my Dell laptop, but is wonky for your card/box?

Dunno.  Card here is a gforce2-mx200, 32megs, your basic throwaway 
card.  X is 4.1.0, and I'm looking to see if I have the vesafb turned 
on, but I cannot find that as an option, and a grep of .config comes 
back empty.

Hmm... I'm using XFree86 4.3.0, which probably makes a big difference.

Also, try tweaking the values of NvAGP in the XF86Config-4 file
(I'm using NvAGP=3, your mileage may vary, depending on whether the 
NVidia AGP support or the agpgart version plays nicer with your box).

Here's the relevant .config I'm using (oh, and I use 'vga=794' at
boot, which gives me a 64x160 char display..

Works for me, hopefully something here will click and we'll figure out
why it isn't working for you...

Thats already in there.

Which gave me a blank screen on an earlier boot attempt...

I turned on the VESA_FB and fonts and its rebuilding now.  Thanks a

The easiest way to get that running on 2.6 is to ask
the manufacturer to open source their driver ;)
