oh gosh, do I have to compile PNG reference library: libpng https://ubuntuforums.org/showthread.php?t=2138623 --> https://sourceforge.net/projects/libpng/?source=navbar

Myy · November 5, 2017

I remember that I compiled it with only doing something like :

apt install libjpeg-dev libpng-dev libdrm-dev libgbm-dev libudev-dev libegl1-mesa-dev libgles2-mesa-dev

The error message is incorrect. The project only needs libpng 1.2 OR 1.5 OR 1.6. Not all at once.

Anyway, no need to compile the required libraries. You should be able to grab them through apt and standard Debian/Ubuntu repositories.

Just try to be as generic as possible when searching for the development headers.

I have the tinker board only attached to HDMI, no keyboard and tried to start it via SSH. Is this a no-go ?

Or is it just the missing driver ?

Will I have to copy your files into those folders - to get the driver ?

cp -r usr/* /usr/
cp -r lib/* /lib/

Myy · November 6, 2017

No, you'll have to :

Reinstall the Mali drivers somehow, or get them in a folder and use the LD_LIBRARY_PATH trick.
If X11 is currently using the display, you'll have to type :

sudo chvt 1 # Equivalent of CTRL+ALT+F1 on a keyboard

To reattach the TTY 1, which will provide a non-locked CRTC, since the X11 CRTC, generally attached to TTY 7, is locked by the X11 process for various valid reasons.

The binary looks good though.

Tido · November 6, 2017

OMG, so it was a must that it runs outside X11. Sorry, I read about 'chvt 1' the first time. I know how to get there.

With regard to performance: The SoC reached 75° , so it is possible that the CPU was throttling, beside that I have this driver messages (box below).

I have never installed Mali drivers - this is a plain armbian nightly with updates: Linux tinkerboard 4.14.0-rc7-rockchip #95 SMP PREEMPT Sun Nov 5 01:47:06 CET 2017 armv7l GNU/Linux

on which I have tried your kernel, but didn't really work. So your kernel is the only thing I ever copied over and switched back to armbian kernel.

If you read this when running glmark2 :

GL_RENDERER: Gallium 0.4 on llvmpipe (LLVM 4.0, 128 bits)

Then you're not using the Mali user-space binary drivers. You're using CPU-bound renderer provided by Mesa.

Now, the user-space binary drivers are a ~~pain in the ass~~ tricky to install, since they require a special ~~snowflake~~ X server from Rockchip.

What I'd suggest is to :

Create a folder
Download libmali-midgard-t76x-r14p0-r0p0-wayland.so from rockchip-linux/libmali repository

Copy the file in the folder you created, then open a shell in this folder and type

mv libmali-midgard-* libmali.so
for file_to_link in libGLESv1_CM.so{,.1} libGLESv2.so{,.2} libEGL.so{,.1} libgbm.so{,.1,.1.0.0} libOpenCL.so{,.1,.1.0.0}; do ln -s libmali.so $file_to_link; done
LD_LIBRARY_PATH=. glmark2-es2-drm

Be sure that your user have read-write access to /dev/mali0. Else the test might also fail.

This should recreate all the necessary library file names that are searched by the OpenGL ES 2.x binary and use the instructions stored in libmali.so.

Aren't you glad that these drivers are so easy to install... Yeah I should create a wrapper script for that thing... seriously.

Tido · November 6, 2017

With your help, this sounds easy, a script(wrapper) might not work in every case. I always login as root, so this shouldn't be a problem.

if you type

file /home/tido/myy-s/mali/libmali.so

what does it return ?

Tido · November 7, 2017

hmm, sounds wrong. Did I download a html instead of the file

 file libmali.so 
libmali.so: HTML document, UTF-8 Unicode text, with very long lines

hmm, I got now a 16MB file instead of the 45Kb from yesterday.

By the way, the "file" command is great. Thank you for showing this to me - I was looking for something like that last time I wanted to proof that I copied over the kernel.

I will try again and report

Wow, in htop CPU is close to Zero !

Temperature: around 50° C steady.

It does need more RAM than before, but not more than 352

Andrew Shahoff · November 7, 2017

@TonyMac32 - Looks like all this needs to be added to the next version of Armbian. Together with H264 codecs ( as by default no VPU video acceleration) . Or scripted.

Tido · November 8, 2017

I don't like to read such.

Andy, have u seen that Tony liked it?

Do u know that u can be grateful, if he does add it and if not, u r free to fix that as well.

Myy · November 8, 2017

@Tido Glad you make it through. As always, ugly terrain and crystal bunny are the most GPU intensive operations.

I guess that you're screen works at 55Hz ?

Anyway, scripting the Mali user-space binary drivers sound nice and all until you realize that, besides wayland (weston only I'd say), DRM (used by almost nobody currently) and fbdev (used only by mediacenter-like distros), they won't be very useful. The X11 ones require a specific X Server, or you'll get a terrific crash when X starts...

Anyway, something like :

mkdir -p ~/.local/lib
cd ~/.local/lib
wget https://github.com/rockchip-linux/libmali/raw/rockchip/lib/arm-linux-gnueabihf/libmali-midgard-t76x-r14p0-r1p0-wayland.so -O libmali.so
for file_to_link in libGLESv1_CM.so{,.1} libGLESv2.so{,.2} libEGL.so{,.1} libgbm.so{,.1,.1.0.0} libOpenCL.so{,.1,.1.0.0}; do ln -s libmali.so $file_to_link; done
echo "alias mali_exec LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:`echo ~/.local/lib`" >> ~/.bashrc

Might do the trick for now. This is actually untested though. This should add a "mali_exec" command that can be used like this :

mali_exec glmark2-es2-drm

Providing a Nvidia Optimus bumblebee-like execution mechanism.

Tido · November 8, 2017

Thank you and Thank YOU very much for your support.
It was a pleasure seeing it drawing the patterns and do this easy @ 53°C and about 7% CPU load.

I checked, 56Hz it says when the tinker board is connected on Windows I ran that Display at 60Hz.
Does this explain the FPS maxium, I saw you reached 59 ?

I guess this reflects your comment about the link I provided you here: https://forum.armbian.com/topic/5416-gpu-driver/?do=findComment&comment=42374

Which means that this test is great for KODI or other applications like a Music-Player that runs with fbdev, but for nothing else. Could it be used in conjunction with a touch-screen ?

Assuming I can get it (the screen) to work on Mainline, I don't see why not.

Indeed, the DRM tests are VSync'ed by default. So you'll get ~1 FPS/Hz .

I got 59 on a cold boot but when using a proper power supply, it stays at 60 for most of the tests, beside crystal bunny and that ugly terrain.

Note that the special X server can be installed more easily if you have you use Zesty or Arftul repositories. However, I really doubt that any Armbian people could help you if that patched X Server becomes broken.

If I have the time, I'll try, once again, to use plasma-desktop + KWin Wayland/DRM with the Mali drivers and see how it goes... It will probably fail miserably though, with no useful error messages.

Tido · November 9, 2017

Armbian currently uses XFCE (which has the biggest lag with regard to GTK+3), which is very light. Plasma-DE is not as heavy as always repeated from some people and tinker board comes with 2GB Ram.
I am not sure if what I heard was related to NEON (KDE) but KDE has taken big steps in direction Wayland.

However, I guess with the outlook to Ubuntu 18.04, more optimization are coming automatically.

TonyMac32 · November 9, 2017

Not to be a demanding troll, but would it be possible to go through this thread, create a tutorial, and stick it in the tutorial section? The parts that can be implemented can be over time, in the meantime a spoon-fed version would help those that have need of it.

Tido · November 9, 2017

All I did was getting GLMARK installed to see if it works properly. Using the libmali-midgard-t76x-r14p0-r1p0-wayland.so is a walk in the park.

The tutorial has already been written by Myy.

Download the Nightly, in my case it was: Armbian_5.34._Tinkerboard_Ubuntu_xenial_dev_4.14.0-rc6_desktop.img - https://dl.armbian.com/tinkerboard/nightly/

and apply above tutorial... in which are the drawbacks already outlined.

boobypi · November 11, 2017

Hello

Just to understand a little bit can we use the binary libmali with lastest kernel with patch (Myy) or it 's necessary to start from 4.4 kernel and port mainline patches to 4.4 kernel?
I buy an rk3328 device only because it's seem there is an kernel - not prehistoric - with gpu available but after some read i find documentation poor and community less active (in number) than sunxi linux team. I hope to be able to compile QT5 webkit with gpu mesa dependancy but maybe it's very early to dream about it

A link to Myy tutorial (RK3288) if already exist need to be under light ^^
Tks for what is sharing here

Tido · November 11, 2017

To my understanding, did you go/read through that thread, I am asking, because just above your post it says: 4.14.0-rc6 .

So have you taken the time to read or not ?

Do you know your link with comment reference isn't working in firefox? I have to check the share button to see proposed url and find the tutorial
Maybe it's more simple to make an pdf or a quote like this :

@Myy, I am just reading about the new features of 4.14 release and come across this: Direct Rendering Manager (DRM)

When you wrote about it, I always thought, why does he care about Digital Rights Management

Yeah, I only care about the the Direct Rendering Manager system (・ω・｀；)

Now, I understand everyone requests for a better documentation on how to install and use the Mali user-space binary drivers. This has been asked on my repository too, and I just started and untested draft in the Wiki of my repository, until I find a better way to format and distribute such documentation.

Still, I repeat, this is untested for now.

Myy · December 25, 2017

So, since I received my microSD correctly, I've been able to test the Tinkerboard with my kernels, using an Armbian image as a basis (along with some microSD cards), and I hit one of the bugs that were reported on my Github page.

This bug triggers an endless stream or error messages which talk about the DRM driver trying to bind something through the MIPI output and failing. Which is perfectly normal since I didn't plug anything in MIPI (nor HDMI when the bug was triggered). Still, blocked the boot phase.
With the original boot.scr, it seemed to trigger a quick reboot continuously, but I don't know if it's because of that bug since I got no output on the serial console when that happened with that configuration (just U-boot output, booting, and U-boot output again, ...). Switching to extlinux/extlinux.conf configuration displayed the error messages, with no reboot.

Anyway, the only solution I found to sidestep the issue at the moment is to avoid adding a mipi_dsi node to the Tinkerboard DTS which... removes the MIPI DSI capabilities of the board, yeah...

So, basically, I don't apply the patch that adds the mipi_dsi node to the rk3288-tinker.dts for the moment.

However, if I get a touchscreen, I'll still try to see if I can enable such functionnality without triggering the same issue.

TonyMac32 · December 25, 2017

Mainline does not support that touchscreen yet, the changes to the drm system from 4.4 to 4.14, and the "special code" used in the 4.4 made me pause before patching any changes in. There are tons of mipi/DSI patches in the pipework, so I'll have to revisit it. For now pulling that node is perfectly acceptable.
