[Patch] unified patch for Xen or Realtime Preemption for 1.0-8776

[Amr_not_Amr]

Can this patch work with NVIDIA-Linux-x86_64-100.14.09 version?

For xen or real-time preemption?

Please note that for 9755 the patch is not necessary any more for real-time
preemption (with recent -rt kernels)! I didn't yet tried it out for 100.14.09,
but it should work OOTB.

I'm pretty sure xen-awareness still needs to be patched in, but the existing
patch should be fairly easy adoptible.

Thanks alot,
I mean for Dom0 kernels ...
should I use this patch or the patch for 1.0-9625 .. or it makes no difference?
and should I follow the exact steps here ... or there are some changes that should be made?

Thanks really

Hi,

running on Debian Etch with 2.6.18-4-xen-amd64 kernel and nvidia-kernel-source package version 1.0.8776-4.

The patch didn't apply easily. I got the following errors :

patching file nv.c
Hunk #2 succeeded at 927 (offset 4 lines).
Hunk #3 succeeded at 941 (offset 4 lines).
Hunk #4 succeeded at 951 (offset 4 lines).
patching file nv-linux.h

Hunk #6 FAILED at 745.
5 out of 6 hunks FAILED -- saving rejects to file nv-linux.h.rej
patching file nv-vm.c
patching file os-agp.c
patching file os-interface.c

The nv-linux.h.rej shows that the differences are already applied to the debian file.

I then compiled with the
MODULE_LOC=tmp/modules module-assistant --unpack-once build nvidia
command (from http://www.debian-administration.org/articles/493) and installed it with no problems.

I then started X and my screen get blank with no possibilities to return to console (Ctrl-Alt-F1/F2/...) or kill the X server (Ctrl-Alt-Backspace)

If I check the X.org logfiles, I got the following differences between a non-Xen kernel with running X and the Xen kernel with non running X :

I hope it can help.

For the moment, I go back to the 'nv' open source driver.

I have redone the process of patching, compilation and test from scratch.

Now, I have a different error on /var/log/XFree86.0.log :

(II) LoadModule: "nvidia"
(WW) Warning, couldn't open module nvidia
(II) UnloadModule: "nvidia"

Very strange because a
/lib/modules # find . -name *nvidia*
./2.6.18-4-amd64/nvidia
./2.6.18-4-amd64/nvidia/nvidia.ko
./2.6.18-4-amd64/kernel/drivers/video/nvidia

./2.6.18-4-xen-amd64/nvidia
./2.6.18-4-xen-amd64/nvidia/nvidia.ko

Anyone got an idea ?
