Phoronix: X.Org Server 1.17 Likely To Have Built-In KMS Modesetting Driver

Work is moving forward to land the generic, KMS-dependent mode-setting driver into the X.Org Server itself...

Performance

Great!

Now the only thing remaining is for GLAMOR to be heavily optimized to outperform like SNA and XAA.

[darkbasic]

It will never outperform SNA.

[mark45]

Does Wayland already have it, does it need it?

[losko]

It will never outperform SNA.

Not on intel... unless they start making faster 3D graphic chips.
Sna is really fast, even on old gen hw.
I think Glamor is most useful on modern AMD/nVidia cards with relatively weak 2D performance.

[Ericg]

It will never outperform SNA.

Keithp was under the impression, at one point, that it could given enough time. That's why they were so impressed with the early galmor optimizations.

Now the only thing remaining is for GLAMOR to be heavily optimized to outperform like SNA and XAA.

OpenGL(GLAMOR) is too CPU/GPU inefficient to be fast as SNA.

[oibaf]

What about xa? Is it supposed to be faster than glamor, using gallium directly without OpenGL?

(xa) : (glamor) = (gallium-nine + wine) : (vanilla wine)

X has no XAA any longer (for quite a while now). But it should be added back, imho. Many old graphic cards that used to work "fine" are now working only unaccelerated (NoAccel in xorg.conf), which is really a PITA.

And the devs of X don't care about that. Thanks!

He's likely talking about XA (as in the Gallium3D state tracker for 2D - http://www.phoronix.com/scan.php?pag...+state+tracker) not the X Server's XAA.
