Thank you for the report.

Another one re update etc & nVidia, but I do not see a duplicate.

I cant reproduce, neither on desktop or server kernel...
My workstation relies on the nvidia-current package so I pretty much ensure it builds / works (for me :) ) 

Anywway, I need the full /var/lib/dkms/nvidia-current/430.64-1.mga7.nonfree/build/make.log

There is no 5.4.2-desktop-2.mga7 directory ???

If it can help...
switch back to kernel 5.3.13
cd /var/lib/dkms/nvidia-current/430.64-1.mga7.nonfree/build
make -> no problem

Edit Makefile to change :

make clean

I have also installed package kernel-source-latest....

Reboot to 5.4.2 and no display....

more tests in 5.4.2 :
cd /var/lib/dkms/nvidia-current/430.64-1.mga7.nonfree/build
make clean
make -> ok

dkms build -m nvidia-current -v 430.64-1.mga7.nonfree -k 5.4.2-desktop-1.mga7 -a x86_64 --no-clean-kerenl -> failed !

So compilation works if i run manually the make but fail if launch
from dkms.
Each time I reboot to 5.4.2, I have a splash screen with 'Building nvidia-current', compilation failed and no display.

What is the difference between the make and dkms ?
If I can bypass dkms on reboot, I'm quite sure it will work.

I need your help ! Thanks !

No need to install the kernel-source, it wont help (and is not used for module builds)

Thats expected as dkms also needs to install built drivers and so on...

So we need to find out why nvidia conftest thinks it found support for set_memory_array_uc/wb

What is the output of ls -l /lib/modules/5.4.2-desktop-1.mga7/

Whats the output of "dkms status" ?

Do you have anything special added on kernel command line ?

Have you patched / rebuilt kernel in any way ?
Are you using any bumblebee or primus packages ?


Also, please revert the Makefile change, then try:

/usr/sbin/dkms_autoinstaller start 5.4.2-desktop-1.mga7

Ok, this seems bad... does it really hang or does it eventually finish ? (wait up to 30 minutes or so)

Also, do you have a lot of kernels, prebuilt kmods  and dkms packages installed ?

rpm -qa |grep kernel |sort

rpm -qa |grep dkms

Also you can try to re-install affected packages in case something has corrupted them, like:

urpmi --replacepkgs dkms kernel-desktop-devel-5.4.2-1.mga7 dkms-nvidia-current

still the same issue...when booting in 5.4.2, dkms try to build nvidia modules and fail....as this is a compilation error, I'm quite sure it could be fix !

Any hint ?

I've tried the latest kernel 5.4.6-desktop-2, same problem.
dkms failed to build nvidia-current module with the same make.log (see contents in the previous posts).
If I try to compile using 'make', nvidia-current is successfully build but
the module is removed at reboot when dkms try to compile the module.
So I'm stuck with kernel 5.3.13.

Maybe an upgrade to nvidia 440.44 could fix this issue ?

Hack to make it build


Can you try tp apply the attached hack

It simply removed the conftest code that detects a function that the newer kernels dont actually support...

dkms failure. Same make.log report.
If I try to compile with 'make', it failed also, I need to revert back to the original conftest.sh file.

Yeah, sorry, I forgot a few changes in that hack...

Never mind that, I just pushed a:

nvidia-current-430.64-2.mga7.nonfree

to mga7 nonfree updates_testing with a better way to fix the mis-detection, please try it out...

Works great :)  I just had to reboot twice. Kernel 5.4.6 running :)
Next step would be to build nvidia driver 440.44 ? Only 440.X provides
cuda 10.2 and GTX 1650 Super support.
Thanks for your help :)

PS: Found another bug when trying to select nonfree updates_testing. I first used 'Mageia Control Center'->'Software management'->'Configure media sources'.
I was able to tick 'Enabled' to select 'Nonfree Updates Testing' but no way to tick 'Updates'.
Using 'drakrpm-edit-media --expert', the 'Updates' field was tickable.

Great.

As it still works here too, we'll release it as an official update
