Unified Xen and real-time preemption patch for 1.0-9625

[JaXXoN]

Hi all!

The patch attached to this post will make the nvidia linux graphics
driver version 1.0-9625 working for Xen or real-time preemption
enabled Linux kernels.

The kernel driver module has been compiled against and tested with
the following kernels on Fedora Core 5 (32 bit):

o 2.6.17-1.2187_FC5smp (standard FC5 kernel)
o 2.6.17-1.2187_FC5xen0 (FC5 xen kernel)
o 2.6.18-rt3 (vanilla kernel + real-time preemption patch)

Please note that when compiling for xen kernels, you will have
to apply "SYSSRC" for "make" or otherwise the build will fail!

The patch may work for x86_64 as well, but has not been
tested. Feedback appreciated.

regards

Bernhard

I'am running ubuntu (egdy eft 2.6.17-10), how can i apply this patch?

[cheval-maxime]

i use the following commands :

patch NVIDIA-Linux-x86-1.0-9625-pkg1.run patch-nv-1.0-9625-xenrt.txt

that's wright? because return error :

patching file NVIDIA-Linux-x86-1.0-9625-pkg1.run
Hunk #1 FAILED at 42.
1 out of 1 hunk FAILED -- saving rejects to file NVIDIA-Linux-x86-1.0-9625-pkg1.run.rej
can't find file to patch at input line 34
Perhaps you should have used the -p or --strip option?
The text leading up to this was:

somebody can help me ?

Please try this:

Boot your system with a "normal" kernel (no xen or rt) and install the
nvidia driver package as appropriate for your distribution. Then
perform the following steps (assuming the driver package and
the patch are located in the same directory and you are logged
in as root):

sh NVIDIA-Linux-x86-1.0-9625-pkg1.run --extract-only
cd NVIDIA-Linux-x86-1.0-9625-pkg1/usr/src/nv
patch -p1 < ../../../../patch-nv-1.0-9625-xenrt.txt
make SYSSRC=$KERNEL_SOURCE_DIR module
cp nvidia.ko $KERNEL_VIDEODRIVER_DIR
depmod -a $KERNEL_VERSION

where

$KERNEL_SOURCE_DIR is something like
"/usr/src/kernels/2.6.17-1.2187_FC5xen0-i686"

$KERNEL_VIDEODRIVER_DIR is something like
"/lib/modules/2.6.17-1.2187_FC5xen0/kernel/drivers/video"

$KERNEL_VERSION is something like:
"2.6.17-1.2187_FC5xen0"

line : "make SYSSRC="/usr/src/xen-headers-2.6.17-5-generic-xen0/" module"

return :

NVIDIA: calling KBUILD...

make[2]: *** Pas de règle pour fabriquer la cible «  /usr/src/xen-headers-2.6.17-5-generic-xen0/arch/i386/Makefile ». Arrêt.
NVIDIA: left KBUILD.

my "normal" kernel is : 2.6.17-10-386
but package avalaible for xen are only generic,server or bigiron.
No problem with version?

I guess this "xen-headers" package only includes *.h files
which is not sufficient for building kernel-modules.
Please check if there is some kind of kernel development
package around for your xen0 kernel (like it is for FC5).
If this is not the case, then i guess you need to recompile
and install the xen0 kernel manually in order to setup
the right infrastructure for kernel module compilation.

Yeeeaaaahhhhh !!!!!!
works fine,
after add kernel-source compilation ("cp" of "make" result)

conclusion : works on ubuntu edgy eft 6.10 2.6.17-10 with xen 2.6.17-5 packages.
6:36am... i can go to sleep happy.
many thanks

I posted this on http://www.nvnews.net/vbulletin/showthread.php?t=78632 but think it might be better here. I have tried the steps described here alas without joy. I did not build the xen kernel but used the rpms that came with FC6.

I can get xen running without the nvidia drivers or else the plain kernel with this driver. I would love to see the twinview with the xen kernel if possible.


nvidia driver version: NVIDIA-Linux-x86_64-1.0-9629-pkg2
Motherboard: MSI K9N Platinum
Graphics card: ASUS EN7300GS (Nvidia7300)
Processor: AMD X2 4200
RAM: 2048MB DDR2
Kernel: kernel-2.6.18-1.2798.fc6 and kernel-xen-2.6.18-1.2798.fc6
Xen version: xen-3.0.3-0.1.rc3

Have I missed something?
Please and thanks.

If you are a debian user, you can find an unofficial package for 1.0.9629 drivers with xen patch applied at

http://www.prato.linux.it/~mnencia/debian/nvidia

You can point your apt to:

deb http://www.prato.linux.it/~mnencia/debian nvidia/
deb-src http://www.prato.linux.it/~mnencia/debian nvidia/

I hope this is useful for someone...

I doubt this will ever be possible...

I run just this setup on my debian sid @home. Xen kernel with 9626 driver and twinview. I even use beryl

[KnutJorgen]

I am able to compile but not to load nvidia with latest fedora kernel.
