Currently I'm using toradex_4.9-2.3.x-imx kernel for my Buildroot system and I plan to do some testing on the Vivante GPU using the examples provided by Freescale :
But I've got errors for following tests :
>>>>>>>> /usr/share/examples/viv_samples/cl11/UnitTest/clinfo Starting...
!!! Error # -1001 at line 156 , in file main.cpp !!!
root@imx-buildroot:~# /usr/share/examples/viv_samples/cl11/fft/fft 1024
Block size: 16
Print result: yes
ERROR:: -32 clCreateContextFromType failed
Also, I noticed that the gpu-viv's driver (i.e. galcore module was failed to load) :
root@imx-buildroot:~# dmesg | grep -i galcore
- [ 2.766399] Galcore version 188.8.131.52331
- [ 2.766630] galcore: probe of 130000.gpu failed with error -22
I'd like to know if this galcore.ko relates to the above tests and why did it fail to load, please ?
Thanks in advance,
