Hi,

 

I am using the yocto Morty release and Linux 4.9.51 kernel "Linux prebuilt binaries" from NXP website for i.MX8 MQEVK board.

 

While running "gputop" it show only GPU3D core and GPU2D/VG core remains 0

 

OUTPUT:

Clients attached to GPU | 0 / 6 (sample_mode: TIME - 1.0 secs)

And got the GPU2D clk_get fail message from "dmesg"

[ 5.445259] galcore: loading out-of-tree module taints kernel.

Is i.MX8QM supports GPU2D/VG?

 

Best Regards,
