rk3188 mali 3D support

[taki-arm]

Hi all.

How to force xorg to work in 3D with GPU Mali.
Kernel module loaded correctly xorg.log writes that .? "module abi major version (11) doesn't match the server's version (14)".
? "xf86openconsole setpgid failed operation not permitted"
?" open /dev/dri/card0 no such file or directory"

I have compiled kernel from > https://github.com/aloksinha2001/Linux3188.git .
It may be that I need to compile kernel with>
<*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)
but if they choose this option the kernel will not boot.

Help appreciated

The kernel you mention (https://github.com/aloksinha2001/Linux3188.git) does not contain working GPU driver.
MALI GPU driver is propriatary and not available as open source.
Kernel driver included into tablets is pre-compiled available as module, but it can't be loaded into linux kernels (because kernel need some code built in in order to load GPU driver module, and this code are not available too)
There is open-source version of MALI driver somewhere, but compile/install instructions were terrible last time I checked, maybe they changed later, if you want you can try to find and compile it.
Just to mention - additionally to kernel GPU driver, you also need X-server driver for GPU. It is also not available.

Thanks for your reply -

You're right, it's not easy, I'm not a Linux expert, but I try to continue.
I'm trying to learn this > http://dri.freedesktop.org/wiki/DRM/
and this work .
kernel needs to be compiled as a module xf86
I have created module "drm ,mali_drm"
mali-driver is now visible in the xorg.log as / dev/dri/card0
What do I still lack the xf86-video-driver = UMP User Space Source Code.


http://www.google.pl/url?sa=t&rct=j&...55980276,d.YmsI have tested from sunxi-linux but without success.
Now I have xf86-video-exynos works better, but of course without 3D.
another problem I'm not sure if there is something messed up in the kernel source from "alok" , apparently requires correction or update.
sunxi-linux-driver sees as "r3p2" and should be "r3p2-01rel1-4"
source code from mali-dev would do well to compile from scratch.

I do not want to start a lengthy discussion, but is it not the case that Mir can use Android drivers, hence that we may be able to use it in the future to drive our MALI gpus?

It seems to me that you're right, you can use the method that he used "olegk0" for rk3066 .
I try all methods at once, and already I do not know so begins Mali to work.

I'm one step further, but again error :

Mali Disassembler

With curiosity I wanted to compare the original file with this mali.ko compiled by me and has come to the conclusion that everything is okey.
The difference is only in this that my file is bigger because I compiled with the debug option mali = on.

It gives links to online debugger to these files.
All in all a great tools online!

hi taki-arm,
a few weeks ago i got libhybris working on my mk809iii stick running ubuntu 12.04; made a kernel and androidfs build and now i can use gralloc, mali.ko and all kind of egl-libs from android. it kind of works, however not yet together with X (i only got a flickering triangle turning around on console screen using androids surfaceflinger on ubuntu, hwcomposer is not yet working).
my question is: which xf86 mali driver do you use or recommend for X? do i also need to build drm as kernel module?

Welcome.

I am using modules ump,drm,mali,mali_drm
xf86 you can try the quickest way of odroid ready package. deb, the only problem is that xorg can scatter, ABI server version differs.
Use the options Finally, add this to your xorg.conf:

Section "ServerFlags"
Option "IgnoreABI" "True"
EndSection

and always please use "dev/fb0" odroid use FB6.

- Does not guarantee the will succeed , xorg can deny , or try to downgrade xorg server version .
If the reboot screen will be black , " rm /etc/X11/xorg.config then coming back to the standard fbdev .
How to remove xorg.config if ist black screen please use another kernel with another initramfs .


I have an old mk809iii, the kernel should work
this is my old kernel, as I find the time it compile new without usb debug, and no screen blinking

I'm not quite sure if this my xorg.conf is correct.
Try it out because original config has a problem with the disappearance of graphics.

I tested on the basis of this> http://archlinuxarm.org/forum/viewtopic.php?f=33&t=5979.
and >http://www.cubieforums.com/index.php?topic=30.0
when you have time you can testing use XMir >https://wiki.ubuntu.com/Mir/Spec?act...direct=MirSpec
technical info and how to build >http://unity.ubuntu.com/mir/
XMir ist flexible and can use all from android !

• good luck and let us know .

Now I have xf86-video-exynos works better, but of course without 3D.

Hi there,

I've been following this as I have a fleet of these that I want to use for a networked-video project - and I need them to be able to play back decent-quality 1080p video. So far I have them stripped to one of the 720p kernels (not Picuntu .. something else I can't remember now) .. playback is OK, but it seems that getting the MALI working will solve all of this, and allow me to move back to a 1080p kernel. I can see how hard it is looking around at other posts as well ...

I have no need for 3D support - only hardware accelerated video. I'm quite new to this and reading this above reply (from taki-arm / 11-05-2013, 06:13 PM), I was wondering if this previous post indicated that you have something that would let the MALI handle video (but not 3D)? Apologies if I'm missing the point here - I'm just curious if there's something half-baked that would actually handle all that I need it to handle.

Best,
S

Hi all

yes you are right if you use "xf86mali-driver" it will help you in video play, but you have to run; videobuf-core.ko, videobuf-vmalloc.ko, videobuf2-core.ko, videobuf2-memops.ko, videobuf2-vmalloc. ko. - And something else.

I'm sorry but I did not have too much time, sometimes trying something after experymento-but lately I have no time.
If you run these modules is the experyment in Mplayer you can use directframebufer or other options, just make experyment.

• do not be surprised if you get video play directly from the hardware and you will not have control over it from the ubuntu.
• a you must use vpu-service.ko module
• Mplayer ist wonderfull.

Thanks so much for this reply - hopefully I'll be able to work according to your suggestion. Mplayer has been good to me so far!

So I need:

xf86mali-driver
videobuf-core.ko
videobuf-vmalloc.ko
videobuf2-core.ko
videobuf2-memops.ko
videobuf2-vmalloc.ko
vpu-service.ko

I'm trying to follow the previous posts in this thread but I'm still unsure about where to find these resources, or whether I need to compile them myself? Apologies - I am a beginner. Any quick help will be greatly appreciated - I understand you don't have much time.

I am running PicUntu 4.5 on a set of the Momi M1 / Chiseltek sticks, if that makes any difference.

Many thanks!

Hi all

extract this and "sudo rm -r /lib/modules/3.0.36+ "
then " sudo cp -a /from folder who ist your download/3.0.36+ /lib/modules/ "

"sudo nano /etc/modules add this >

Thanks again for this help!

I followed those instructions, rebooted, and got the blinking cursor. Rebooted holding down 'shift' key and got a prompt - logged in as root, then tried 'startx' and the log shows that it experiences a fatal server error - 'no screens found'. Last lines before that were:

Initializing built-in extension XFree86-DRI
Initializing built-in extension DRI2
Loading extension GLX

Fatal server error:
No screens found

Any thoughts?
