i.MX6 - How to test the GPU

[Ansari]

Hi,

We are using imx6Q custom platform for our development which is based on sabresd platform with Linux 3.14.28_1.0.0-GA BSP.

We would like to know the testing procedure to test the GPU.

we have run the "/unit_tests/gpu.sh" command  and got the below error.

~ ~

vdkGetDisplay() failed.

CreateWindow() failed.

press ESC to escape...

/unit_tests/gpu.sh: line 20: cd: /opt/viv_samples/hal/: No such file or directory

~

Please help us to test the GPU.

Regards,

Ansari

Hi Abdul,

To run test applications, you have to first load the GPU driver.

To load the GPU driver, use the following command:

"insmod <PATH>/fgalcore.ko"

to un-install GPU driver, run the following command:

"rmmod <PATH>/galcore.ko"

Note: The path of galcore.ko can be found by the following command:

  "cd / && find . -name "galcore.ko"

Also there is a Graphics user Guide document in the BSP installation folder please check it.

What is the difference between fgalcore.ko and galcore.ko?

These are the command I try to execute:

root@imx6sxsabresd:/unit_tests# cd / && find . -name "galcore.ko"

./lib/modules/4.1.15-1.1.0+ga4d2a08/extra/galcore.ko

root@imx6sxsabresd:/# cd / && find . -name "*galcore.ko*"

root@imx6sxsabresd:/# insmod /lib/modules/4.1.15-1.1.0+ga4d2a08/extra/galcore.ko

galcore: module is already loaded/modules/4.1.15-1.1.0+ga4d2a08/extra/galcore.ko

insmod: ERROR: could not insert module /lib/modules/4.1.15-1.1.0+ga4d2a08/extra/galcore.ko: Invalid parameters

I get an error, but the module doesn't seem to be installed and running ...

root@imx6sxsabresd:/# lsmod

Module                  Size  Used by

mx6s_capture           14960  0

mxc_dcic                6544  0

ov5640_camera          19961  0

Could you please help me to fix this error?
