Currently I’m using toradex_4.9-2.3.x-imx kernel for my Buildroot system and I plan to do some testing on th Vivante GPU using the examples provided by Freescale :
But I’ve got errors for following tests :
root@imx-buildroot:~# /usr/share/examples/viv_samples/cl11/UnitTest/clinfo >>>>>>>> /usr/share/examples/viv_samples/cl11/UnitTest/clinfo Starting... !!! Error # -1001 at line 156 , in file main.cpp !!! !!! Exiting... root@imx-buildroot:~# /usr/share/examples/viv_samples/cl11/fft/fft 1024 Block size: 16 Print result: yes Initializing device(s)... 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 220.127.116.11331 [ 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,
