Phoronix: xf86-video-modesetting TearFree Page-Flipping Merged

The xf86-video-modesetting work covered a month ago over "TearFree" page flipping support has been merged to the X.Org Server for whenever the next release ends up happening...

By the way, in the Intel driver TearFree worked perfectly, and then I noticed that when I switched to modesetting, there was no TearFree support.

So, it was as easy as adding just one tiny option to the X server? And no Wayland was needed after all?

It would be super nice if that feature could be just "flipped" runtime without the need to restart the whole server.
Or I would just use a light compositor.

This is great, so one can get vsync or not in games as he please with an efficient vsync implementation based on hw capabilities, versus a more generic one that would be otherwise used by the in-game vsync and also switch it on and off on the fly.
This is what i get from the article and your answer.
Correct!?

Why not use xorg.conf?

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "modesetting"
    Option      "AccelMethod"    "glamor"
    Option      "TearFree"       "on"
EndSection​

Try it for yourself. I imagine it would make no difference since TearFree is not V-Sync, but I can't speak from experience.

They wanted to know if this could be toggled at runtime.

Wayland fanboys: X.org is not maintained, is dead.

It did not, it broke with every app triggering page flipping and likely still does. Xorg on Intel is extra terrible, probably worse than Nvidia.
