NVIDIA Shares Wayland Driver Roadmap, Encourages Vulkan Wayland Compositors

([NVIDIA] 3 Hours Ago NVIDIA Wayland Plans)


At the X.Org Developer's Conference (XDC 2024) happening this week in Montreal, NVIDIA shared a road-map around their Wayland plans as well as encouraging Wayland compositors to target the Vulkan API.

Austin Shafer and James Jones of the NVIDIA Linux/Unix team presented at XDC 2024 on some of their recent Wayland driver features -- namely explicit sync support -- as well as going on to cover some future NVIDIA Linux driver plans.

[1]

They shared NVIDIA has been ramping up their internal Wayland testing and among the future items they plan to pursue are supporting the upstream high dynamic range (HDR) color pipeline user-space API. They are also looking at internal display muxing on Wayland, enabling the FBDEV and modeset kernel module parameter options for their driver by default, and nvidia-settings utility under Wayland being read-only settings.

They have hit some additional pain points in Wayland support that they are exploring.

NVIDIA's Austin Shafer also presented on Vulkan for Wayland compositors. He encourages OpenGL no longer being the "default" API used for compositor development but Vulkan being a much better fit.

In particular, Vulkan's explicit design makes it much better for Wayland compositors, better multi-device awareness, and other features.

The Worst Lines of Verse
For a start, we can rule out James Grainger's promising line:
"Come, muse, let us sing of rats."
Grainger (1721-67) did not have the courage of his convictions and deleted
these words on discovering that his listeners dissolved into spontaneous
laughter the instant they were read out.
No such reluctance afflicted Adam Lindsay Gordon (1833-70) who was
inspired by the subject of war.
"Flash! flash! bang! bang! and we blazed away,
And the grey roof reddened and rang;
Flash! flash! and I felt his bullet flay
The tip of my ear. Flash! bang!"
By contrast, Cheshire cheese provoked John Armstrong (1709-79):
"... that which Cestria sends, tenacious paste of solid milk..."
While John Bidlake was guided by a compassion for vegetables:
"The sluggard carrot sleeps his day in bed,
The crippled pea alone that cannot stand."
George Crabbe (1754-1832) wrote:
"And I was ask'd and authorized to go
To seek the firm of Clutterbuck and Co."
William Balmford explored the possibilities of religious verse:
"So 'tis with Christians, Nature being weak
While in this world, are liable to leak."
And William Wordsworth showed that he could do it if he really tried when
describing a pond:
"I've measured it from side to side;
Tis three feet long and two feet wide."
-- Stephen Pile, "The Book of Heroic Failures"
