Question

good day everyone,

 

Just for fun , i try to run gpu miner on OPI win plus, with open CL.


https://github.com/hominoids/sgminer-arm

 

but i face several problems and It would be nice if some buddy  could help me.

 

I cant install all needed libs:

root@orangepiwin:~# apt-get install  mali-fbdev -y
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package mali-fbdev

To install Download ARM Computer Vision and Machine Learning library,  is that value true:

usr/lib/arm_compute-v18.03-bin-linux/lib/linux-armv7a-neon-cl

2. Build

cd libdri2

make install                                                                    
cd ..                 

# Step 2: build video driver                              
                                                                                
cd xf86-video-fbturbo                                                           
autoreconf -i                                                                   
./configure --prefix=/usr                                                       
make                                                                            
make install                                                                    
cd ..     

# Step 3: build GL wrapper                                               
                                                                                
cd glshim                                                                       
cmake .                                                                         
make                                                                            
cp lib/libGL.so.1 /usr/lib/ # replace the software GL library with the wrapper
cd ..    
3. Configure your system

- configure your kernel to allocate memory for the GPU

- make sure mali and mali_drm kernel modules are loaded

- give your user permissions to access /dev/ump and /dev/mali

- configure Xorg to use fbturbo driver

 

4. Test:

# run a basic test
glxgears   

# install and run a GL benchmark 
apt-get -y install globs  
/usr/lib/globs/benchmarks/GL_pointz/gl_pointz                            

# try to run a real game
apt-get -y install billard-gl
billard-gl  
This all worked out for me rather nicely. The only issue I have encountered is a segfault that many GL programs get when they shut down. I'm currently debugging this issue, but it would be helpful to know others experience it as well, and perhaps get some advice from people experienced in GLX or SDL.

 

Edit: I know glxgears is not a real benchmark, but let me give you some numbers to make it clear what I'm talking about. Results are from Orange Pi PC clocked at 1296000 Hz (and are CPU-bound):

user@bananapi:~$ glxgears
LIBGL: Initialising glshim
libGL: built on Jun 12 2016 06:12:01
LIBGL: Current folder is:/home/user
libGL:loaded: libGLESv1_CM.so
libGL:loaded: libEGL.so
2074 frames in 5.0 seconds = 414.688 FPS
2071 frames in 5.0 seconds = 414.085 FPS
2070 frames in 5.0 seconds = 413.915 FPS
^C

But  cat get it work

So far I tried it with booth kernels  4.19 and 3.10

will this generally work on OPI WIN?

 

is the instruction correct?

 

 

greetings
