NVIDIA Prepares XWayland OpenGL/Vulkan Acceleration Support

Things Nvidia is still partially or even entirely missing on Wayland (apart from GBM)

For the pull request code it looks that they are only implementing DMA-BUF over EGLStreams.
So the GBM vs EGLStreams are still in the Wayland mess.

Windows HAVE to mantain compatibility, Linux don't.
If drivers are mainlined in the Linux tree, ABI change are not a problem and kernel devs have no interest on mantain ABI compatibility for out of tree drivers (nvidia).
If nvidia have no interest in mainlining his driver, then they will have to deal with the problem, their choice.
I would not say windows is "far ahead", quite the opposite!

My point is that Windows having to maintain backwards compatibility makes it harder for Windows and yet they have done a better job

Btw: Nvidia Vulkan driver does not support mailbox vsync mode, which basically is a requirement for proper presentation on Wayland with uncapped frame rate.

I wonder how they will get past the DMA buf restrictions

What restrictions would those be?

Things Nvidia is still partially or even entirely missing on Wayland (apart from GBM):
-custom EDID support
-VRR
-manual fan controls
-overclocking/undervolting
-color/gamma adjustment
-VAAPI in Firefox
...

-> Might be usable in ten years or so.

How are things like fan controls and overclocking/undervolting Wayland specific exactly? I wouldn't think VAAPI would be either?

Their previous attempted approach was criticised for violating the GPL.

It is in Nvidia world, where options like "coolbits" are Xorg output centric. Afaik nvidia-smi also works "headless", but it doesn't offer everything.

At last, nvidia.will support wayland... By then I will have switche back to the red team. Hopefully by that time the vrr situation with hdmi will have been resolved. Then the last bit will be hdr!

Those should begin this spring in time for the Fedora 34 release as likely the first distribution shipping standalone XWayland packages.

Yeah no, my money's still on Arch

Also, could this be the open source announcement Nvidia has teased last year?

Its not exactly being wayland specific lots of this functionality Nvidia binary driver has implemented as X11 specific as the configuration has to be in the x.org configuration file. Of course this is problem when you need to alter those setting at kernel boot so stuff works.

That is a very good question....
