Kernel 2.6.16 - Nvidia and Nvsound drivers - fixes

[drbenway]

Hi people.

Kernel 2.6.16 and the Nvidia graphics and nforce sound drivers are not compatible. If you try to install them you will not be able to build the kernel module.

There is however a patch for each driver.

Nvidia graphics - http://www.nvnews.net/vbulletin/showthread.php?t=62021

Nforce (nvsound) - https://bugs.gentoo.org/show_bug.cgi?id=119284
-> Just click on the fix link, then copy the text into a file (call it something.diff) then use the same technique as mentioned in the Nvidia graphics link to patch the driver
-> even though it says GCC 4.1 patch it also works with GCC 3.5 (i am using 3.5)

I hope this helps someone, I stopped using SUSE purely due to the fact the NFORCE driver didn't work, i am so happy that i moved to Gentoo !

Cheers

well the 8174 nvidia-kernel ebuild compiled for me. But it would not start. dmesg screamed about client not supporting versioning and thats it. The stuff I tried between 6299 and this did not even compile.

Hi.

The guide is meant to work with the latest binary driver from nvidia.com not the ebuild.

Have a go with the latest driver.

I found creating a custom installer, just like they suggested for the Nvidia Graphics drivers, a nice solution for when I do happen to need to reinstall the nvsound drivers on the 2.6.16xxx series kernels.
Thought I'd share my example of how I went about it, as it's slightly different than the way you'd do it for the graphics drivers:

NOTE: I did all of this from an empty directory called /tmp/NFORCE, where I moved the NFORCE-Linux-x86-1.0-0310-pkg1 folder into, that had been previously patched...

Hi.

Just to update you......

The Good :-

Nvidia have released a new nvidia driver that works in kernel 2.6.16 (without patching).

http://www.nvidia.com/object/linux_display_ia32_1.0-8756.html

The Bad:-

- It seems to make the refresh rate stuck at 70 hz (intead of 85), any i do cannot change the refresh rate.

I have reverted to the previous driver and the patch, but please try the new one and see if it works for you.

Cheers

Hi all,
I just finished installing gentoo but i have a problem installing the nvidia driver. I've downloaded the newest driver from nvidia and i run it but i got an error message that sas the driver isent kopiled with the same gcc version as the kernel, and that nvidia.ko can't be loaded.
This cant be pausible because i didnt do any update what so ever. To be sure, because i am a complet novice with gentoo, i got the latest kernel source 2.6.15-gentoo-r1 and installed it. After all that i tried installing the nvidia driver but i got the same error. I read the nvidia FAQ for this problem, but i dont know how to set IGNORE_CC_MISMATCH... .

Hi andrei.neagu.

I sounds like either

1) Maybe gcc has been upgraded since you compiled the kernel? - most likely

You can check this by comparing these 2 values:-

cat /proc/version -> will tell you what version of gcc was used to compile the kernel
gcc -v -> will tell you what your default gcc version is

- make sure they match, if not recompile the kernel and try again.

2) Or the kernel source dir is incorrect - ie /usr/src/linux is pointing to the incorrect place?

[andrei.neagu]

well tanks.
The gcc version is 3.3.5
and in the /proc/version is the same thing and the link is good it points to /usr/src/linux-2.6.15-gentoo-r1.
Well i updated the the gcc to 3.4.5 and rekompiled the kernel.
On gcc -v i get 3.4.5
but in proc/version the gcc version is 3.3.5
and the nvidia driver stil dosen't work.
how do you update the /proc/version or shoudn't it be done automaticly?
thanks.

Try running a: gcc-config -l

Like this:
