iMX53 GPU - Very bad performance

santiagoperez — Fri, 27 Jun 2014 19:53:50 GMT

Hi,

I'm testing the imX53 GPU to accelerate my Qt applications but it is working really slow: 14fps for the es11ex test and 6fps for the Qt4.8.5 hellogl2_demo.

I reinstall ltib in the VmWare machine, install with the docs and this post (Building Qt for i.MX5x) as referene with no luck. The gpu is enabled, the driver installed, tried out also with a patch but no luck. My bsp version is L2.6.35_11.09.01_ER.

I have searched a lotand tried everything with no luck. Can anyone give me any approach or guide me in the right direction?.

Thanks to all in advance,

Santiago

It looks like you are really not using the GPU. Did you build the BSP with enviroment variable BSP_GPU_BASE=1 BSP_GPU_OPENGLES=1 BSP_GPU_OPENVG=1? This test application verifies the basic functionality of OpengGL ES 1.1. It is included in the release image. Also, You must have three separate packages installed to get good GPU performance in X11. You must have the amd-gpu-x11-bin-mx51, the xserver Xorg package, and the libz160 debian packages installed. Only the Ubuntu file system currently supports the GPU integration and acceleration. Also, you must make the system in inserting the UIO driver (uio_pdrv_genirq.ko) before the GPU driver to enable accleration of X11 drawing. You can use ?lsmod? to see if both modules are loaded. Check you ?/etc/modules? file to make sure the UIO is before GPU. Lastly, you can verify that the GPU driver is intsalled into X properly by running ?simple_draw 1000?. The resulting frames/sec should be over 100 (on most resolutions). Check the GPU_SDK < http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX53QSB&fpsp=1&tab=Design_Tools_Tab >

Hope this helps

Hi Bio_TICFSL,

thanks for your reply, very encouraging.

It looks like you are really not using the GPU.

Thats really probable but all the steps made should have enabled it.

Did you build the BSP with enviroment variable BSP_GPU_BASE=1 BSP_GPU_OPENGLES=1 BSP_GPU_OPENVG=1?

I couldn't finde them. Where are they supposed to be and how to enable them?

This test application verifies the basic functionality of OpengGL ES 1.1. It is included in the release image.

In release image (Ubuntu) works fine, also the simple_draw application (212fps).

Also, You must have three separate packages installed to get good GPU performance in X11. You must have the amd-gpu-x11-bin-mx51, the xserver Xorg package, and the libz160 debian packages installed.

Yes, they are. The hole list of packages selected, based on Building Qt for i.MX5x and other sites/docs, are:

I have also checked the driver in the kernel configuration, enabled by default.

Only the Ubuntu file system currently supports the GPU integration and acceleration.

I'm building my BSP based on the minimal rootfs. Do you mean only Ubuntu rootfs will really enable my GPU?

Also, you must make the system in inserting the UIO driver (uio_pdrv_genirq.ko) before the GPU driver to enable accleration of X11 drawing. You can use ?lsmod? to see if both modules are loaded. Check you ?/etc/modules? file to make sure the UIO is before GPU. Lastly, you can verify that the GPU driver is intsalled into X properly by running ?simple_draw 1000?. The resulting frames/sec should be over 100 (on most resolutions).

Neither both drivers are present in ?lsmod? and neither by ?modprobe -l?. I alse checked it in Ubuntu release image and they are also not present

The ?/etc/modules? folder doesn't exist in my rootfs, but it does in Ubuntu, empty.

The simple_draw test works perfect in Ubuntu (212fps) also all the gpu-sdk software, but they don't in my minimal rootfs.

I really can't find out what is missing.

Thanks in advance.
