rk3188 mali 3D support

[taki-arm]

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?

if you installed the xf86-video-driver from this post above? >http://www.freaktab.com/showthread.p...l=1#post138961 read it carefully.

if you have not yet installed the xf86-video-driver, it seems to me that you miss xorg.conf.

- do so open a terminal and sudo nano /etc/X11/xorg.conf and paste this config
---------------------------------------------------------------------
#xorg.conf
Section "Monitor"
Identifier "Monitor0"
Option "DPI" "96 x 96"
ModelName "Monitor Model"
DisplaySize 1920 1080
EndSection
Section "Device"
#Option "ShadowFB" "true"
Identifier "Card0"
Driver "fbdev"
Option "fbdev" "/dev/fb0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
EndSection

Section "Module"
Load "dbe"
EndSection

-----------------------------------------------------------------
ctrl+o save it.
ctrl+x exit.
reboot.
this is the default xorg.conf for fbdev.

if this does not help a spare modules on the>http://www.sendspace.com/file/sxnsuk

Great - thanks for the tip. I started fresh, installed the xf86-video-driver, installed the modules that you uploaded, and then used the xorg.conf that you have in the last post. The only change I had to make was to the line:

DisplaySize 1920 1080

It seems to want DisplaySize in mm - so with it set to 1920 x 1080, the font on the screen was tiny. My screen was around 530 x 280 mm so I put that in and it's perfect.

Otherwise it works!

Now (hopefully) a last question. I'm opening h.264 videos in mplayer, and wondering which options to try to get work over to the GPU? So far trying:

mplayer -vo dga moviefile.mov

is getting the video into the directframebuffer (fullscreen) but there are still issues with 'No accelerated colorspace conversion found from yuv420p to rgb5651e'. The video is still extremely slow and relying on sw scaling to achieve the colorspace conversion.

[ No control over video while it's playing, as you mentioned - at least with dga. ]

Maybe I just need to adapt in my video encoding.

I'll try some other options and post any success. If you have any tips, let me know.

Again - Thanks for the advice with this.

I'm following your trials closely and looking forward to results. I'm also trying to do the same in Debian Jessie using Enlightenment window manager.

If you just want to try then I've created an updated Ubuntu 12.04 RFS with the necessary kernel modules and binary userspace drivers which you can download and boot from on https://plus.google.com/109451178006...ts/NEWG6Mtz5U7

linuxium, thanks for that image and sharing it! What steps need to be done to run another linux distro with the same kernel modules and binary userspace drivers? Should it be enough just to copy some file (e.g. from /lib/modules/*) to other's OS root fs?

It is not that simple because "compiling and installing" the binary userspace drivers puts files in other places e.g. /usr/lib etc. so you would also have to fight your way through http://linux-sunxi.org/Binary_drivers.

Cool, thank you.

Whats the best way to flash this to NAND in Windows?

My way on MK802 IV-->

1- Download Mali drivers https://www.dropbox.com/s/8lp0qeilwcqnjce/gpu.rar
2- Put folder gpu into /lib/modules/3.0.36+/kernel/drivers
3- Open shell and:

depmod -a
Add ump and mali to modules --> nano /etc/modules and add this line
______
ump
mali
______

Create a permisions(add lines)
nano /etc/udev/rules.d/50-mali.rules
KERNEL=="mali", MODE="0660", GROUP="video"
KERNEL=="ump", MODE="0660", GROUP="video"


Second part: Compiling

Need ->

apt-get install git libdri2-dev xorg-dev xutils-dev git build-essential x11proto-dri2-dev libltdl-dev libtool automake

mkdir /install;cd /install

git clone https://github.com/robclark/libdri2
cd libdri2
./autogen.sh
./configure
make
make install
cd /install
git clone https://github.com/linux-sunxi/sunxi-mali.git
cd sunxi-mali
git submodule init
git submodule update
make config VERSION=r3p2-01rel1 ABI=armhf
make install
cd /install
git clone -b 0.4.0 https://github.com/ssvb/xf86-video-fbturbo.git
cd xf86-video-fbturbo
autoreconf -vi
./configure --prefix=/usr
make
make install
cp xorg.conf /etc/X11/xorg.conf

reboot

PD: If you have problems with egl version running es2gears, best way is:
mv /usr/lib/arm-linux-gnueabihf/mesa-egl/ /usr/lib/arm-linux-gnueabihf/.mesa-egl/
mv /usr/lib/libEGL.so /usr/lib/libEGL.so.old
mv /usr/lib/libEGL.so.1.4 /usr/lib/libEGL.so.1.4.old
mv /usr/lib/libGLESv1_CM.so /usr/lib/libGLESv1_CM.so.old
mv /usr/lib/libGLESv1_CM.so.1.1 /usr/lib/libGLESv1_CM.so.1.1.old
mv /usr/lib/libGLESv2.so /usr/lib/libGLESv2.so.old
mv /usr/lib/libGLESv2.so.2.0 /usr/lib/libGLESv2.so.2.0.old
cd /install/sunxi-mali
make install
cd /install/xf86-video-fbturbo
autoreconf -vi
./configure --prefix=/usr
make
make install
reboot

This works for my 802IV:
EGL_VERSION = 1.4 Linux-r3p2-01rel2

Cool, thank you.

Whats the best way to flash this to NAND in Windows?

For the Radxa Rock for example, for dualboot (android and ubuntu) download and unzip this firmware 'https://drive.google.com/file/d/0B99O3A0dDe67WG85YUNKLXNqdFE' or for just ubuntu download and unzip this firmware 'https://drive.google.com/file/d/0B99O3A0dDe67bFZucW9NT0hocVE' and flash using using 'RKBatchTool' on Windows, and then download and unzip the RFS 'https://drive.google.com/file/d/0B99O3A0dDe67S1hQQ2VybldVYU0' and write to SD card or USB using 'Win32 Disk Imager' on Windows. Boot from the SD card or USB and follow the on-screen prompts to install to NAND.

Znet, thank you for providing detailed step-by-step instructions!
I will try to follow them for distro I am using.

Thank you Ian!!

Your bootloader made the installation easy and the performance of Ubuntu is impressive. :0)

I wonder if there are any other benefits in enabling 3D mali support apart from ability to play 3D games?
