xf86-video-nouveau 1.0.11

[ken@…]

​http://lists.freedesktop.org/archives/nouveau/2014-September/018623.html

Highlights:
  - Support for server managed fd's.
  - Glamor support.
  - Maxwell support.
  - DRI3 and initial Present support.
  - vsync'ed kms pageflip performance fixes when running on Linux 3.13+
  - Multi-display vsync, vblank, swap scheduling, timestamping fixes.
  - Multi x-screen support fixes.
  - ZaphodHead support on for multiple outputs per x-screen.
  - EXA nv-10 fixes.
  - Enable sync of swaps to vblank by default (Option GLXVblank "on").
  - Disable pseudo-triplebuffering by default (Option SwapLimit "1").

For the books, glamor support might change some text in other places.

NB I don't have any hardware to test this, so I'll leave it for someone who does.

I've a Nvidia card, but I do not know what glamor is. Accepting anyway...

Glamor is an acceleration library using the card's 3D capabilities to accelerate 2D rendering. It is hoped it will make writing new video drivers easier. It is now part of xorg-server.

Mentioned on the xorg-server page (it needs libepoxy) and under the ati video driver.

At the moment, the newest ati (radeon southern islands and central islands) chips need it. It is available for intel and radeons from r600 onwards, but not the default for those.

The new version works like a charm with "AccelMethod" "exa", but I am unable to have it work with glamor, although "AccelMethod" "glamor" is accepted. Problem is, when I add this option, I get:

[0.000] (II) Loading sub module "glamoregl"
[0.000] (II) LoadModule: "glamoregl"

but later

Also, with exa, I had (before the AIGLX lines):

instead of just, with glamor:

[0.000] (II) NOUVEAU(0): [GLAMOR] initialised

I do not know if I am doing something wrong (missing option for the driver or whatnot). I have added a nvidia.conf file in /etc/X11/xorg.conf.d:

Section "Device"
        Identifier "Nividia"
        Driver "nouveau"
        Option "AccelMethod" "glamor"
EndSection

I see that some changes are needed for Mesa (see ticket #5497) and xorg-server (see r14252). I'll try those (actually already done for Mesa), to see if I can get glamor to work. If not, I'll commit as is, stating that glamor has been added but is not functional yet (on my cards, GT220 (NVA5) and Quadro 600 (NVC1)).

[Armin K]

I believe that Glamor is only used by Maxwell (and will be used for any later) hardware, so I don't think you can use it just yet.

[Pierre Labastie]

Thanks, Armin!

What the doc says is that glamor is the default for Maxwell, and that you can enable it for the others by setting "AccelMethod" to "glamor". I guess that is not yet true. I have no Maxwell GPU here, so I cannot test...
