Title: WARNING for NVIDA users: kernel 5.9 coming in sid
Post by: Camelot on 2020/11/02, 11:02:58: As of today, sid/unstable comes with kernel 5.9~~, NVIDIA users should hold back kernel 5.8.×~~.

Code: [Select]
apt-mark hold linux-headers-siduction-amd64 apt-mark hold linux-image-siduction-amd64
Code: [Select]
The following packages have been kept back: linux-headers-siduction-amd64 (5.8-17 => 5.9-3) linux-image-siduction-amd64 (5.8-17 => 5.9-3) 0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

Why?: NVIDIA Doesn't Expect To Have Linux 5.9 Driver Support For Another Month (https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-Linux-5.9-Delayed)

But don't forget, if NVIDIA drivers work again…

Post by: sunrat on 2020/11/02, 13:23:28: One of the admins at Debian User Forums reported the current 450.80.02-1 nvidia driver in sid works with the current sid 5.9 kernel - http://forums.debian.net/viewtopic.php?f=30&t=147803#p729675
I queried him about it as I read that Phoronix article too. I haven't tested it as I use Nouveau on my siduction system.

The driver was build quckly, but afterwords it needed 5 minutes till the installation of the new kernel was finished.
After reboot, all is fine.

Post by: seasons on 2020/11/03, 16:24:53: The main nvidia module will work with kernel 5.9. However, the nvidia-uvm module will not. The upshot is that those that need CUDA and CUDA-based functions (like NVDEC/NVENC) should keep a 5.8 kernel handy until Nvidia releases a driver that works around the GPL symbol issue.

Why not? There is nothing special about kernel 5.9 and the main part of the nvidia driver. As usual, patches have been floating out there since the 5.9 rc's and the Debian maintainers applied them: (For 340 driver, see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972430 )

The symbol issue affects the nvidia-uvm module, which is the Nvidia Unified Memory module, used for CUDA.

Post by: ajavibp on 2020/11/03, 20:36:42: Legacy drivers tend to stop working with each new version, and sometimes it takes a long time to work again.

Nvidia driver 455.38 from experimental is installing and working correctly on kernel 5.9.3-towo.2 (2 GPUs):
So the nvidia-uvm module is loaded and CUDA or NVDEC is working correctly? That's the issue here; not whether the main part of driver installs and works (Read the Article!). We don't need 50 more "works for me" posts if people aren't going to test CUDA.

OK, how does one test CUDA? (I have never done a CUDA test).

Thanks.

Post by: seasons on 2020/11/05, 16:19:53: Probably the easiest way to check CUDA is by checking if nvidia-uvm is loaded:
Code: [Select]
lsmod | grep nvidia

$ lsmod | grep nvidia nvidia_drm 57344 6 drm_kms_helper 258048 1 nvidia_drm nvidia_modeset 1220608 19 nvidia_drm nvidia 27746304 1232 nvidia_modeset drm 618496 9 drm_kms_helper,nvidia_drm
So ....

Great graphics, no CUDA. :'(
