nvidia-drivers and kernel-4.0.0

Message

nvidia-drivers-340.76 (which I need because of an old 9600GT card)
does not install on new kernel-4.0.0

here's the errors in the build log:

Code: Select all

/var/tmp/portage/x11-drivers/nvidia-drivers-340.76/work/kernel/nv-pat.c:38:5: error: implicit declaration of function ‘read_cr4’ [-Werror=implicit-function-declaration]

this is an unsupported kernel but I wonder if anyone has a patch ...

Same problem here, nvidia-drivers-340.76 because an older card.

There is a patch at https://devtalk.nvidia.com/default/topi ... tions-fix/ but it needs a little change because the file that should be patched could not be found.
So I changed it into:

 static int nv_determine_pat_mode(void)

put it in /etc/portage/patches/x11-drivers/nvidia-drivers

So now I am running gentoo-4.0.0

Thank you houtworm!

This worked for me too (older card also).

It's not working for me...

I wonder why... i have 9600GT and nvidia-drivers-340.76

After putting patch into /etc/portage/patches/x11-drivers/nvidia-drivers/kernel-4.0.0-patch, I still get this:

are you sure the patch is being applied?

shots in the dark:

patch file needs to be of form xxxxx.patch ?

blank space at end of each line of patch (this has bit me) ?

Can somebody help me?! btw, did someone tried with kernel-4.0.3?

yes, it worked for me ...

But - strangely - it failed the first time, installed correctly the second time

gentoosapien · Post by **gentoosapien** » Sat May 16, 2015 2:11 pm

I'v patched the file by hand - the patch from /etc/portage/patch... doesn't applied by user epatch

"Failed Patch: ${patchname}!

The Patch works also with kernel 4.0.3 - Thanks a lot for this!

gienah · Post by **gienah** » Wed May 20, 2015 1:23 pm

In case there are problems with copy/pasting the patch, I have tar'd up the patches that I use on my system running
kernel 4.0.4-hardened-r1 with x11-drivers/nvidia-drivers-340.76 here:

http://dev.gentoo.org/~gienah/unsupport ... .14.tar.gz

to extract, as root:

Code: Select all

cd /
tar xvf etc-portage-patches-x11-drivers-nvidia-drivers-340.76-for-kernel-gt-3.14.tar.gz

If you are not running a hardened kernel then the pax patch can be removed:

Code: Select all

rm /etc/portage/patches/x11-drivers/nvidia-drivers-340.76/nvidia-drivers-331.49-pax-uvm.patch

I have also tried this on Kernel 4.0.5 now.

papas · Post by **papas** » Wed Jun 17, 2015 8:48 pm

its not working for me too (kernel 4.0.5 , nvidia-304-125)

gienah · Post by **gienah** » Thu Jun 18, 2015 7:08 am

Well of course x11-drivers/nvidia-drivers-304.125 is a different major version (304) to x11-drivers/nvidia-drivers-340.76 (340), so
you would not really expect it to work.

Please try saving this patch:

https://projects.archlinux.org/svntogit ... a93c932d82

Which I found by looking on the Nvidia Linux forum, finding the answer:

https://devtalk.nvidia.com/default/topi ... kernel-4-/

To the file (creating the directory if it does not already exist)

Code: Select all

/etc/portage/patches/x11-drivers/nvidia-drivers-304.125/nvidia-drivers-304.125-kernel-4.0.patch

And let us know if it works or not. My hardware is not supported by the 304 driver.

mani001 · Post by **mani001** » Thu Jun 18, 2015 2:13 pm

I'm also on x11-drivers/nvidia-drivers-304.125 and bumped into the same problem. Unfortunately, the patch didn't work for me (I put it in the right directory in /etc/portage/patches and made sure it was applied checking the output from emerge...). I just hope nvidia doesn't leave us like this

tomtom69 · Post by **tomtom69** » Thu Jun 18, 2015 5:03 pm

I had the same problem.
Besides the patch mentioned, I generated an additional patch to address the "f_dentry" error, which I put into the file
/etc/portage/patches/x11-drivers/nvidia-drivers-304.125/nvidia-drivers-304.125-kernel-4.0.5.patch
(see patch below)
With this patch in addition to the patch mentioned by gienah I can successfully compile and run a 4.0.5 kernel with nvidia-drivers-304.125
(Sorry if the patch is not directly downloadable or displayed inconveniently - this is the first time I do this in a forum so maybe it is not as convenient as can be)

Besides the patch mentioned, I generated an additional patch to address the "f_dentry" error, which I put into the file
/etc/portage/patches/x11-drivers/nvidia-drivers-304.125/nvidia-drivers-304.125-kernel-4.0.5.patch
(see patch below)
With this patch in addition to the patch mentioned by gienah I can successfully compile and run a 4.0.5 kernel with nvidia-drivers-304.125
(Sorry if the patch is not directly downloadable or displayed inconveniently - this is the first time I do this in a forum so maybe it is not as convenient as can be)

Strange. I pasted exactly the file from my /etc/portage/patches/x11-drivers/nvidia-drivers-304.125/nvidia-drivers-304.125-kernel-4.0.5.patch
I now copied the patch again and fresh into pastebin. Could you try this one?:

Now the patch its fine but still i cant build the driver, maybe there is something wrong with my system.
Can anybody else try the patch?
Thank you again tomtom69.

tomtom69, your patch (along with the other one from the NVIDIA forums) did the trick for me

Thank you very much!!

Actually, because I couldn't use the patch as it was, I created myself a slightly modified version. Here it goes, just in case

http://pastebin.com/d1htUQGX

Cheers!!
