XWayland GLAMOR & DRI3 Support Added In Mainline X.Org Server

[mannerov]

Without benchmarks I can predict the results:

Gnome doesn't bypass compositing yet for fullscreen app, thus decreasing performance because of the copy done by compositing.
Present support is not merged for XWayland, thus it uses the Present fallback, which caps the number of copies it does to 60 per seconds (in contrary to dri2 with vblank_mode=0).

Thus the result is: slower for slow apps ( < 60 fps), faster for fast apps (> 60 fps), if we compare to a desktop bypassing compositing, and using dri2.

Benchmark?

Exciting!

I wish to see a Wayland vs XWayland vs X.org benchmark.

Could it be possible that nvidia releases a Wayland-compatible version of their closed source driver in conjunction with the XServer 1.16 release? If I remember correctly there was a discussion about XWayland compatibility and their driver on a mailing list a few weeks ago, I might be wrong though.

Or is XWayland support not necessary to be compatible with the 1.16 release?

Is anything special needed to make use of GLAMOR for Xwayland like further patches to mutter?

You need mesa 10.2 and mutter 3.13.x ... 3.12 does not work with the "new" (ddx less) xwayland.

Is anything special needed to make use of GLAMOR for Xwayland like further patches to mutter? I have built Xwayland from Kristians own Xorg branch a month ago, which already had these changes as far as I know, but in Gnome 3.12 it was still using llvmpipe for Xwayland. The mutter build I'm using is a bit old though. It's the snapshot right after Xwayland DDX support was added since the newest version of mutter don't work with the rest of Gnome 3.12.
