xf86-video-opentegra

Has anyone tried using xf86-video-opentegra on their nvidia tegra based systems ?

It compiled but can't get X to use it at it complains it cant fond stuff in /dev/dri/
Not sure how to fix it but I suspect that newer kernel is required with different DRM interface.
Damn it looks like that next step up from 3.0 is 3.8 ... but that requires a whole load more of work (uboot and gpt) and my AC100 is not collaborating with some hardware issues !!!

Anyone else had a go ?

This is how I compiled and packaged it:

Code:

git clone --depth 1 https://github.com/grate-driver/xf86-video-opentegra

cd xf86-video-opentegra

./autogen.sh --prefix=/usr --sysconfdir=/etc --localstatedir=/var --datadir=/usr --docdir=/usr/doc

make

mkdir -p /usr/src/ac100/pkg

make install DESTDIR=/usr/src/ac100/pkg

cd /usr/src/ac100/pkg

makepkg -l y -c y ../xf86-video-opentegra-0.6.0-arm-1.tgz

I've built the opentegra driver and it'll be in -current today.
You can test it :-)

If I try the one in current I get this:

Code:

[  709.092] (II) LoadModule: "opentegra"

[  709.093] (II) Loading /usr/lib/xorg/modules/drivers/opentegra_drv.so

[  709.093] (II) Module opentegra: vendor="X.Org Foundation"

[  709.093]    compiled for 1.15.2, module version = 0.6.0

[  709.098] (EE) module ABI major version (15) doesn't match the server's version (14)

[  709.098] (II) UnloadModule: "opentegra"

[  709.098] (II) Unloading opentegra

[  709.098] (EE) Failed to load module "opentegra" (module requirement mismatch, 0)

[  709.098] (II) LoadModule: "fbdev"

Ok I'm using a -current package on 14.1 ... maybe it's normal.

If I use the one I built this is what I get:

Code:

[  1026.428] (II) LoadModule: "opentegra"

[  1026.428] (II) Loading /usr/lib/xorg/modules/drivers/opentegra_drv.so

[  1026.429] (II) opentegra: Open Source Driver for NVIDIA Tegra: kms

[  1026.448] (WW) Falling back to old probe method for opentegra

[  1026.449] (EE) No devices detected.

[  1026.449] (EE) 

Fatal server error:

I'm going to try running current from SD without upgrading the system on internal flash just to see if the -current package works.

Tried also with current but I get the same "open /dev/dri/card0: No such file or directory" error.

Do you have DRI in your Kernel?

http://wiki.gentoo.org/wiki/Xorg/Har...What_is_DRI.3F

I'll look closer in the kernel setup asap ... but CONFIG_DRM is set to m in /proc/config.gz
and it don't help much if I load it manually ... maybe the old 3.0 kernels had incomplete DRM/DRI ?

root@pepa:~# file /dev/dri/card0

/dev/dri/card0: character special

'X -configure' doesn't find anything though:

Code:

Number of created screens does not match number of detected devices.

  Configuration failed.

(EE) Server terminated with error (2). Closing log file.

but I don't know that it would anyway since I don't believe that the required driver for the Trimslice is in the kernel.
