My board is based on imx6q and the bsp is built from yocto (kernel version 3.10.17).
When I run OpenGL demos from fsl-gpu-sdk/GLES20_X11, some of them (e.g. 07_EnvironmentMapping) will output the following message: [ 1] libGAL: Performing a software resolve!
In fact, when 07_EvnironmentMapping is running, the cpu usage is about 2%, and that of Xorg is lower than 3%.
Does this message mean that the demo is rendered by software ? Could anyone tell me how to judge whether an OpenGL application is accelerated by GPU ?
Thanks very much in advance.
Hi Alejandro,
Thanks for you reply.
I ran the examples in a terminal, 07_EnvironmentMapping and 08_EnvironmentMappingRefraction output the message to the terminal.
# cd /opt/fsl-gpu-sdk/GLES20_X11
# ./07_EnvironmentMapping
Did you try the examples in a terminal ?
Following the steps of Freescale_Yocto_Project_User's_Guide(uboot and kernel are modified according to our board), we built the image. After the image is built, the fsl-gpu-sdk examples are in /opt. We made no modifications to these examples.
Best Regards,
Spark
