Phoronix: NVIDIA Doesn't Expect To Have Linux 5.9 Driver Support For Another Month

While NVIDIA is usually quite timely in supporting new versions of the Linux kernel and aim to have out a driver by the end of the release candidates for new series, in the case of the recently minted Linux 5.9 kernel it's taking a lot longer...

I know the people who actually do write the Nvidia Driver for Linux do awesome work and do a lot to make this driver as performant as possible, so here is a read for their bosses:

I'm used to the proprietary driver not always working with the latest Linux kernel, but what exactly is wrong with i.e. kernel 5.9.1 and Nvidia driver 455.28? I need to ask, because I have both up and running and didn't notice any issues. It runs X11 with Xfce and I can even start a game using WINE/DXVK, which means Vulkan must be working, too.

It's only nvidia_uvm module that has issues with kernel-5.9, the rest work fine.

This only affects cuda and opencl.

Second the above. I had to forego UVM, ie OpenCL and CUDA.
Desktop works fine.

The cuda binaries are frag. The regular user dkms compiles fine. And virtualbox is also toast on 5.9 in case you are into that.

[rene]

the result on relying on closed and GPL violating vendor blobs ;-)

[oleid]

I wonder what will be first: RDNA2 support on ROCm or CUDA on 5.9++

Beta works fine here.

RDNA2? What about RDNA1? There's no support yet!
