nvidia 384.90 refuses to build against rt-kernels

[oberon-manjaro]

Seems with the newest nvidia driver we can no longer supply nvidia-extramodules...

The kernel you are installing for is a PREEMPT_RT kernel!

The NVIDIA driver does not support real-time kernels. If you 
are using a stock distribution kernel, please install 
a variant of this kernel that does not have the PREEMPT_RT 
patch set applied; if this is a custom kernel, please 
install a standard Linux kernel.  Then try installing the 
NVIDIA kernel module again.

*** Failed PREEMPT_RT sanity check. Bailing out! ***

Happens with both linux49 and 411 base kernels.
Any ideas @philmmanjaro ?

https://aur.archlinux.org/packages/nvidia-rt/ doesn't work either?

Thank you. It seems the way nvidia checks for PREEMPT_RT has changed.
I found a way to adjust and circumvent the test. It's building now 😉
We'll just need to see then if it does in fact work on a system ...

[philmmanjaro]

Well, simply post about it and somebody will test it ;)

@budimanjojo can you please check if latest nvidia 384.90 extramodule works? Packages are now on unstable branch.

Also announced in our forum.

Hi guys,
I installed 4.4.32-apollo-1.5.0-RT (a RT-kernel based on official Linux Kernel 4.4.32 with some modifications.). And I executed the shell script to install the Nvidia driver (My GPU is GTX 1050Ti).

The terminal print: "successfully install" , but the screen resolution is still very very slow（the nvidia card still does not work）.

After executing "nvidia-smi", the terminal showed "failed to initialize NVML: Driver/library version mismatch". how should I do?

Looking forward to your reply.

[oberon-manjaro]

I cannot really help you there since you are using a non-manjaro kernel.
You can either use one of our rt-kernels or you will have to build your matching extramodules yourself.
However this isn't related to this issue here, which has been closed long time ago btw 😉

[oberon-manjaro]

If you're going to build your own extra module, the PKGBUILD can be found here for reference. Of course you will have to adjust it for any different kernel.

Thank you @oberon-manjaro , I have to use the apollo-kernel ，because we use an open powerful autonomous driving platform:Apollo . I am trying to solve this problem,and I will share it after I get it.
