Vivante GC2000 drivers?

[Michele Adduci]

Hi

i am trying to figuring out the problem of not working graphics on Wandboard Quad with latest Ubuntu (13.04).
Until now i've installed X11 and Xfce environment, but it cannot start, while i can only use terminal by pressing Ctrl+Alt+F7.

The Xorg.log shows the following message:

which clearly confirms the missing of Vivante drivers. 
I tried to compile the xserver-xorg-video-imx-viv-3.0.35-4.0.0 drivers contained in Ubuntu 12.04 image but many errors occur during the code compilation, due old libraries versions. 
I couldn't find any suitable new version of that package, maybe any of you has found it?

https://community.freescale.com/message/328267#328267 you can try hardfloat drivers from here. I don't know if they work. Maybe you need only libs. Or libs+kernel... If you manage to install them can you pm me or write to group about what is needed?

[Michele Adduci]

the main point is that i can run glxgears as root on Ubuntu 13.04 and it works (i use ssh -X for X11 forwarding) and it is shown fine in my system at ~40 FPS, so the GPU itself works fine, but i cannot force Xorg to load the GPU module / driver.

ok i have fixed it.
Seems like xorg.conf was a little bit messy.

Now LXDE is loaded successfully on Ubuntu 13.04. I'll manage to create an image and upload it within the next days.

I have also installed mesa-utils package 

Here my xorg.conf file:

Hey, this are great news!!

Could you post what how you did this, so i can add acceleration to my debian image and update the download?
Or maybe add a tutorial directly to the new wandboard wiki, i am sure there are more people trying to get this done.

Thanks in advance, martin

[Michele Adduci]

Hi

i still didn't test the 3D acceleration inside the desktop environment but Xorg is booting (from VNC i can access to X environment).
Basically i've followed Robert Nelson's tutorial and i was playing around with xserver-xorg vivante package i've found on Ubuntu 12.04 image.
After installing mesa driver and doing the symbolic links for libraries, i have removed  the .Xauthority file contained in /home/ubuntu/ folder and then installed xfce4.
From what i see, wlan0 is disabled (and i don't know how to enable it - tried with sudo ifconfig wlan0 up but it gave me error).

I will create in next days a full tutorial to reach X environment and i will test it with 3D acceleration further.

I don't know if 40FPS with glxgears are fine or Wandboard Quad could do more

At 40 fps glxgears its not using h/w acceleration, it should around 400-600 at 720p. I spent consider time getting this working for the xubuntu build on the GK802. The current vivante X11 drivers seem to be compatible up to Xorg 11.4, therefore you won't be able to get h/w acceleration unless the linux distro you are deploying supports Xorg 11.4 or below.  This is explains why it works for ubuntu 11.10 & 12.04 (armel). Ubuntu 13.04 has moved to xorg 13.

The 3.5.7 GPU code works with Xorg 1.14.

No; 3.5.7 does not support Wandboard or GK802. Both need to be add there.

[Michele Adduci]

And what about Etna_viv project? (Opensource vivante drivers for GC processors)
Did anybody give that a try?

[Michele Adduci]

Is there any new with kernel 3.10/11/12 and Vivante graphic drivers?
Was anybody able to gain hw acceleration under newer versions of Ubuntu/Debian?

Best,

Michele

I was kinda hoping Freescale would at-least base there acceleration
drivers on imx_drm stack with the new v3.10.x based bsp, but i haven't
seen anything yet on that..

Hello,
I did not try it out yet I just wanted to inform you that the etna_viv driver made some progress. There now is experimental support for the gc2000 chip. I will check it out as soon as I have some time to spare. I think this are great news for the Wandboard community. The gc880 was well supported, and soon the quad users might get rid of the blobs as well.

more intel here:

[Michele Adduci]

Hi Kevin

that sounds great! At the moment, I'm setting a new Ubuntu image, built on a harddrive, thanks to the sata boot hack and i will check this new version of etna_viv.

I hope it can be soon a good replacement for the closed Vivante drivers.

Best

Michele

[Michele Adduci]

Hi

I've tried etna_viv drivers but they are framebuffer only ones and without DRI support, so X11 cannot work.

So far, in these days I've done some trials with all the resources available online and the result is terrible.

A demo image in armhf with X11 and 3D  acceleration is impossible to be built, just because the single libraries are simply full of errors in C code.

All the xserver-xorg-imx packages (from 3.0.35 to 3.5.7 - 3.10.9 one isn´t available) don't compile because of errors. I've installed all the packages required by the configuration step, including the add of the path to imx6 sdk, which has to be set in "viv-config.sh" script.

So far, until now I have a kernel 3.12.6 coming from Robert Nelson's repository with Vivante module enabled and loaded (I've ported the driver from official 3.10.9 alpha kernel provided by Freescale), but the xorg video module cannot be built.

If anybody has hints or suggestion, please reply here or contact me.

Kind regards and happy new year

Michele

[Michele Adduci]

For those interested, I've created a patch for the mainline kernel 3.13 taken from Robert Nelson's repository.

It adds the GPU driver coming from kernel 3.10.9-alpha of Freescale. So far, I've compiled the kernel and it works fine.

Hoping it can help.

There are some working rootfs made by jas_hacks. He has compiled in gpu support on both debian and ubuntu
