Here You has a Workaround for Kernel 5.9: http://rglinuxtech.com/?p=2844

Yes, but that solution incorporates applying the patch, and compiling the kernel myself, which is beyond my knowledge. And it fails in following versions, I read: jeff.chua.linux <https://forums.developer.nvidia.com/u/jeff.chua.linux> Patch works, but with latest linux git pull (commit 071a0578b0ce0b0e543d1e38ee6926b9cc21c198), compile fails … So, maybe a solution for some, but alas not for me.

Remember, the Nvidia driver IS NOT OPEN SOURCE.

Yes, I know for some years already... But anyhow, thanks for your reply. By the way, your post arrives twofold here. regards, Jogchum

Hi,

I was wondering, is a build of the nvida-uvm module for kernel >= 5.9 on the horizon? For some projects I really need CUDA support, and for that this module is needed, I understand.

Hi Install the hard way?

NVIDIA-SMI 455.46.02 Driver Version: 455.46.02 CUDA Version: 11.1

As I discovered my old GT710 doesn't run (lc0) so had to upgrade the gpu...

Is better if You upgrade to an AMD GPU, and then You forget all the problems related to the GPU drivers! Cheers

(Made a mistake I've made before, answering not to the list, but to the poster himself... Sorry Malcolm!) Op 05-12-2020 om 16:10 schreef Malcolm:

Well, that gives ls /lib/modules/`uname -r`/kernel/drivers/video/ backlight  fbdev  nvidia-drm.ko  nvidia.ko  nvidia-modeset.ko nvidia-uvm.ko  vgastate.ko.xz so one would say it it there... But insmod doesn't find it. Do I have to use the absolute path ( /lib/modules/5.9.8-2-default/kernel/drivers/video/nvidia-uvm.ko) when involing insmod?

Because insmod looks for a file with the exact name you gave it.

You should always be using modprobe unless you explicitly want to load just compiled module from a local directory and know what you are doing.

AH, that's it. Used modprobe before, long time ago, but didn't know the difference with insmod. Module is loaded now, I see with lsmod. See if blender and meshroom see it. Thanks!

Blender still doesn't, "No compatible GPU's found for path tracing." it reports under CUDA. So I have to investigate that further.

Did you try 455.45.01 from <https://forums.developer.nvidia.com/t/linux-solaris-and-freebsd-driver-455-45-01-short-lived-branch-release/159759> ? According to <http://rglinuxtech.com/?p=2857> that one runs even with 5.10-rc I'm rather busy with another project at the moment, I 'll be back on

I'm running 455.38 for my optimus laptop. Self compiled via dkms, but the uvm module builds w/o issues.

With 5.9 or higher? Without patching the kernel?

Yes, of course. Just plain TW kernel. woodstock:~% uname -a Linux woodstock.pitnet 5.9.11-1-default #1 SMP Wed Nov 25 05:49:27 UTC 2020 (91426ef) x86_64 x86_64 x86_64 GNU/Linux woodstock:~% ls /lib/modules/5.9.11-1-default/updates/ bbswitch.ko nvidia.ko.xz nvidia-uvm.ko.xz nvidia-drm.ko.xz nvidia-modeset.ko.xz

Thanks. Just learned that Nvidia's 455 series seems to have a workaround for the 5.9 issue.

Yes, that seems to be the case, Martin. Stefan Dirsch expects a long-term release of that beast, which should be out in the next couple of days. Meanwhile, we're working an G04 fix for 5.10 (without CUDA support of course..). If all goes well, we're in a good shape for 5.10 NVIDIA-wise. The same *doesn't* hold true for drdb, Virtualbox, random external kernel module of your choice, unfortunately. Cheers, Pete

Care to open a bug report if you know the build failure of specific KMP for 5.10? At least, drbd package maintainer is pretty responsive, AFAIK.

https://bugzilla.opensuse.org/show_bug.cgi?id=1179708 If you ever looked into this package, this is no wonder, as it massages the code with coccinelle on the flight... Technically ambitious, but a saying of Linus Torvalds comes to mind: https://lore.kernel.org/lkml/Pine.LNX.4.44.0207141708470.20233-100000@home.t...

I believe that we should put more packages in OBS Kernel:HEAD:KMP project to catch such build problems before the TW update.

Yes, that would be nice and is exactly, what I do in my kernel projects: home:frispete:kernel{,:HEAD}

It doesn't contain VirtualBox; or is this intentionally removed?

Well, VB is special in many ways, which starts by being owned from Oracle. If suffers from: error: implicit declaration of function 'alloc_vm_area' Just another fallout of Christoph Hellwig's crusade against off tree kernel modules, in the sake of clean ups, of course. But a fix is in the works: https://www.virtualbox.org/ticket/20055 Working on incorporating this patch in our build now.. Cheers, Pete
