nvidia-tegra is not built for armhf

[Marcus Comstedt]

It loks like this package is only built for armel, not for armhf which is the architecture best suited for Tegra(2&3).

Please make an armhf build.

Thanks.

I think this is not a bug. Canonical cannot build a closed source Nvidia driver for armel. You should ask nvidia for that. BTW I have Toshiba ac100 and it would be awesome to have the driver for armhf.

I had a bit typo there. Canonical can't build closed source driver for armhf...

Um, ok, so where is Nvidia's bugtracker then?

Oddly, there seems to be an nvidia-tegra driver compiled for hardfp out there, as confirmed by "Plagman" who claims to represent Nvidia Corp.
See: http://www.nvnews.net/vbulletin/showthread.php?p=2495420

The driver seems to be available to the Meego people for porting onto the "trimslice" device:

Does anybody know why it is not available to Ubuntu?

Status changed to 'Confirmed' because the bug affects multiple users.

beta hardfp nvidia-tegra driver is available at http://developer.nvidia.com/linux-tegra

Thanks. I tried installing it on my AC100, but it seems like some kernel module is missing.

From Xorg.0.log:

[...]

Ok, my bad. It turns out that I had to create a symlink from tegra_drv.so -> tegra_dri.abi11.so since my Xorg uses video driver ABI 11.0...

Now the driver actually loads. I can't seem to get any GL going though; both glxinfo and glxgears complain that there are no RGB visuals.

[Marc Dietrich (marvin24)]

which is normal because the driver doesn't support opengl (only opengl/es). try es2_info from mesa-utils-extra.

[Marcus Comstedt (marcus-mc)]

es2_info and es2gears both give me software rendering.

Also, there seems to be something wrong with video overlays, the Y apears to be offset from the UV vertically by maybe 4 pixels...

In 12.10 (Quantal) the package is only built for armhf now.
