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) Galcore version:6.2.4.150331, gpuperfcnt:c122d9db0de3, 1.4 HW:3D:GC7000,Rev:6214 3D Cores:1,2D Cores:0,VG Cores:0 DDR0: r:300.51,w:0.16 DDR1: PID RES(kB) CONT(kB) VIRT(kB) Non-PGD(kB) Total(kB) CMD 3193 33810 0 0 0 33810 weston 3202 24216 0 0 0 24216 weston-desktop- 3201 3980 0 0 0 3980 weston-keyboard TOT: 62006 0 0 0 62006 TOT_CON: - - - - 69065

And got the GPU2D clk_get fail message from "dmesg"

Is i.MX8QM supports GPU2D/VG?

Hi,

Please make sure to look at the i.MX8M product page:

i.MX 8M Applications Processor | Arm® Cortex®-A53, Cortex-M4 | 4K display resolution |NXP

You'll see i.MX8M doesn't have a 2G GPU ;-)

Regards,

Gary
