Subject: nvidia-kernel-source: Version fails to build using linux-image-2.6.20-1-k7 2.6.20-1~experimental.1~snapshot.8305

Date: Wed, 21 Feb 2007 22:05:40 -0500

Package: nvidia-kernel-source
Version: 1.0.9746-2
Severity: normal

Well, I am tracking experimental at the moment. I have

linux-image-2.6.20-1-k7 2.6.20-1~experimental.1~snapshot.8305
linux-kbuild-2.6.20 2.6.20~rc6-1~experimental.1~snapshot.8221 
linux-headers-2.6.20-1-k7 2.6.20-1~experimental.1~snapshot.8305

At this point, using module-assistant to build nvidia-kernel or 
"make module" in the "nv" dir, I get the following fatal problem:

make -f /usr/src/linux-headers-2.6.20-1-k7/scripts/Makefile.modpost
  scripts/mod/modpost -m  -i /usr/src/linux-headers-2.6.20-1-k7/Module.symvers -I /usr/src/modules/nvidia-kernel/nv/Module.symvers -o 
/usr/src/modules/nvidia-kernel/nv/Module.symvers -w  /usr/src/modules/nvidia-kernel/nv/nvidia.o
FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol 'paravirt_ops'
make[3]: *** [__modpost] Error 1
make[2]: *** [modules] Error 2
NVIDIA: left KBUILD.
nvidia.ko failed to build!
make[1]: *** [module] Error 1
make: *** [module] Error 2

The setup will not compile. The nv module works for now. Not a big deal.

[Message part 1 (text/plain, inline)]

With 2.6.20 hitting unstable I had a go at upgrading and encountered the
same issue as the original reporter.

Using "module-assistant a-i nvidia" with nvidia-kenerl-source
v1.0.9746-2 from experimental I get compilation errors due to
"GPL-incompatible module nvidia.ko uses GPL-only symbol"

http://lwn.net/Articles/205644/ has some info on the kernel changes that
are causing the problems, but I'm not sure what the best way to deal
with it in Debian is.

Is it a kernel bug? An nvidia bug? or something we users have to deal
with on our own?

Subject: Temporary workaround

Date: Thu, 19 Apr 2007 14:07:28 +0200

I had the same error with recent and old versions of nvidia source:

nvidia-kernel-source 1.0.8776-4
nvidia-kernel-source 1.0.9746-2
and even original nvidia package NVIDIA-Linux-x86-1.0-9755-pkg1.run

my workaround was to disable paravirtualization in kernel
(paravirt_ops have EXPORT_SYMBOL_GPL in Module.symvers and I think this 
couses the problem)
I've done this, more or less, that way:

1. Install linux-source-2.6.20-1-686
2. Uncompress /usr/src/linux-source-2.6.20-1-686.tar.bz2
3. delete symlink /lib/modules/2.6.20-1-686/build and make new (ln -s 
/usr/src/linux-source-2.6.20 /lib/modules/2.6.20-1-686/build)
4. copy .config from headers to sources (cp 
/usr/src/linux-headers-2.6.20-1-686/.config /usr/src/linux-source-2.6.20)
5. in sources dir 'make menuconfig' and disable paravirtualization in 
'processor features'
6. make prepare
7. make scripts
8. now i could compile and install nvidia kernel driver

block 411949 by 419943
thanks

From "More stuff for 2.6.22" <http://lwn.net/Articles/233315/>:

        Numerous changes to the paravirt_ops methods have been made.
        Additionally, paravirt_ops is no longer a GPL-only export.

Now that this change has been reverted, could we *please* see the same
change made in the Debian kernel!

Subject: nvidia-kernel-source: Same happens with 2.6.21 from testing too

Date: Wed, 11 Jul 2007 10:47:32 +0200

Package: nvidia-kernel-source
Version: 1.0.9755-1
Followup-For: Bug #411949

FWIW, the same problem still happens on 2.6.21 kernel from testing atm.

Too bad version 100.14.11-1 doesn't work either with 2.6.21 according to #430921 (didn't test myself).

Hope this helps,
