Phoronix: KDE's KWin Running On Wayland Gets Real-Time Scheduling

When KDE's KWin is acting as a Wayland compositor, there's now a real-time scheduling policy to ensure the graphical system is always responsive...

Gnome really needs something similar for mouse cursor responsiveness. Bad enough that even with flat cursor acceleration setting in Gnome Tweaks it doesn't feel like real 1:1 position mapping, but additionally the cursor also likes to stop and stutter occasionally. How please is this supposed to be "production ready"?
Not meant as Gnome bashing, it just seem to me that many people aren't critical enough how well Wayland compositors work these days compared to Xorg.

Finally Why Kwin involves CPu instead of GPu? When Kde will be ready for wayland?

Pretty sure Mac OS does this and has wired memory as well. The system can be deadlocked and my mouse still zooms around.

Nice on Linux is so powerful it’s probably a safer option. Running a task as nice -15 it might as well be real-time.

This will be an awesome improvement for Kwin to always stay responsive! Sounds like a dream, the window manager, applications without issues, keyboard and mouse work even if there are some faulty applications :-) If now the graphic drivers wouldn't be able to crash the hole system anymore and just would do a proper reser... I guess too many whises for a day :-)

GPU can handle input (keyboard, mice, touchpad...)?

In theory it's fine, but in practise is it often young code, which causes hangs and irresponsiveness. To give the still young Wayland components real-time priority bears risks of its own. I'd say it's a ballsy move, but not necessarily the wisest.

wow very nice! as sometimes when a program freezes it also freezes the whole system and you cannot kill it. why they dont implement this for X as well?
