Using z160 GPU on a custom board

oliviernasralla — Sun, 23 Dec 2012 18:27:06 GMT

Hello,

anyone know (or have an idea) how to use the GPU of the imx51 on a board that does not come from freescale. My board come from another company and use his own BSP which doesn't provide the GPU driver and library.

I tried to copy all include, lib and bin files from the package "amd-gpu-bin-mx51-10.11.01" present in the freescale BSP source to my rootfs but I am not able to start any example. I get always the same error which say the application is not present, but it is...

Did someone already try something similar?

Thanks

Olivier

Please check the i.MX51 part number on your board. There is no GPU in i.MX512 and i.MX513.

Thanks for answer.

I have the i.mx515, which have the GPU.

Actually I stay at the same place with my problem, have you some idea about the way I should add the GPU support on my board?

To be more precise, what I did is copy in /usr/lib/ of my rootfs:

lib2dz160.so
lib2dz430.so
libcsi.a
libEGL.so
libGLESv1_CM.so
libGLESv2.so
libgsl.so
libOpenVG.so
libres.a
libz160.so

and copy to /usr/include/ in my rootfs:

EGL folder
- egl.h
- eglext.h
- eglfslext.h
- eglplatform.h
- eglplatform_1.4.h
GLES folder
- egl.h
- gl.h
- glext.h
- gl_extensions.h
- glplatform.h
GLES2 folder
- gl2.h
- gl2amdext.h
- gl2ext.h
- gl2platform.h
KHR folder
- khrplatform.h
VG folder
- ext.h
- ftvg_utils.h
- openvg.h
- vgu.h
z160.h

Is it enough to use the GPU or I need to load a driver on the board or something more?

thanks

Olivier

Hi,

At this time i'm tryin to give an imx53 board a performance-boost by enabling hardware-acceleration for X11.

I've been trying to build and include hardware support for "Driver for Freescale IMX processors: i.MX5x Z160" into the X11 ( buildroot 2016-11) . Running ( building for) latest LINUX (long-term) kernel 4.4.43.

I've been able to compile and run the imx_X11 driver ... so far .. but it bails out ... with

(EE) imx(0): Unable to access Z160 GPU

Any clue ?

I'm kind of stuck now... anyone out .. that can give me a hint ?

Best Regards

Noel
