IMX6q GPU driver, galcore does not load

Branched to a new discussion

I have been trying to enable 3D acceleration on an i.MX6Q SABRE Lite board using a custom kernel, built from Freescale's kernel tree, rel_imx_3.0.35_4.0.0 release . Unfortunately, the galcore module doesn't load:


galcore: probe of galcore.0 failed with error -22


Output of uname -a:


Linux alarm 3.0.35-02864-g54750ff #21 SMP PREEMPT Sun Jun 16 21:09:43 BRT 2013 armv7l GNU/Linux


Kernel command line:


video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24 video=mxcfb1:off video=mxcfb2:off fbmem=28M console=ttymxc1,115200 vmalloc=192M root=/dev/mmcblk0p1 rootwait consoleblank=0 enable_wait_mode=off

dmesg log and kernel configuration are attached.
