[Nouveau] Wayland doesn't work outside of X with nouveau, and it should
Since pageflip support for NV50 cards was added on the 9th, wayland should
work for me outside of X, but all I'm getting is apparently random chunks
of uninitialized video memory.
It seems nobody has looked into the problem who has an Nvidia card. I have
no idea where to begin.
I added my PCI ID to mesa's dri2_driver_map so I could use egl_dri2 since
egl_dri2 is what is being used with Intel cards, to make sure it wasn't
just a difference between egl_dri2 and egl_gallium which I normally use.
Wayland works fine under X this way with egl_dri2.
I think similar results are happening with ATI/AMD cards, so wayland
without X is only working on Intel cards.
Build instructions for Wayland are here:
http://wayland.freedesktop.org/building.html
They should be up to date and thorough. I have an easier build script for
Ubuntu Maverick here: http://www.chaosreigns.com/wayland/ubuntu.html
You should be able to just run the compositor program outside of X to get
DRM output.
My console output (which I don't think contains anything interesting):
X output, which works:

DRM output, not working:
http://www.chaosreigns.com/wayland/wayland.drm.txt
With strace:

The script I used to run it:

To get your PCI ID:
$ lspci -nv |grep VGA
05:00.0 0300: 10de:0611 (rev a2) (prog-if 00 [VGA controller])
^^^^
My Mesa patch to add my PCI ID so I can use egl_dri2 (I sent this to
mesa-dev a while ago, but it didn't get applied - this one is updated).
You just need to add another line with your PCI ID in nouveau_chip_ids[].
What would it take to get these in mesa?

Then you can use something like nouveau_device_open_existing and the struct that you get from that contains "chipset" which can be used to determine what you have.> [PATCH] Add nVidia Corporation G92 [GeForce 8800 GT] to dri2_driver_map > > --- > ?src/egl/drivers/dri2/platform_drm.c | ? ?5 +++++ > ?1 files changed, 5 insertions(+), 0 deletions(-) > > diff --git a/src/egl/drivers/dri2/platform_drm.c b/src/egl/drivers/dri2/platform_drm.c > index 42939a5..4652011 100644 > --- a/src/egl/drivers/dri2/platform_drm.c > +++ b/src/egl/drivers/dri2/platform_drm.c > @@ -558,6 +558,10 @@ const int r600_chip_ids[] = { > ? ?0x6779, /* PCI_CHIP_CAICOS_6779 */ > ?}; > > +const int nouveau_chip_ids[] = { > + ? 0x0611, /* G92 [GeForce 8800 GT] */ > +}; > + > ?const struct dri2_driver_map driver_map[] = { > ? ?{ 0x8086, "i915", i915_chip_ids, ARRAY_SIZE(i915_chip_ids) }, > ? ?{ 0x8086, "i965", i965_chip_ids, ARRAY_SIZE(i965_chip_ids) }, > @@ -565,6 +569,7 @@ const struct dri2_driver_map driver_map[] = { > ? ?{ 0x1002, "r200", r200_chip_ids, ARRAY_SIZE(r200_chip_ids) }, > ? ?{ 0x1002, "r300", r300_chip_ids, ARRAY_SIZE(r300_chip_ids) }, > ? ?{ 0x1002, "r600", r600_chip_ids, ARRAY_SIZE(r600_chip_ids) }, > + ? { 0x10de, "nouveau", nouveau_chip_ids, ARRAY_SIZE(nouveau_chip_ids) }, > ?}; > > ?char * > -- > 1.7.1 > > _______________________________________________ > Nouveau mailing list > Nouveau at lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/nouveau >-- Far away from the primal instinct, the song seems to fade away, the river get wider between your thoughts and the things we do and say.
