Need clarification about DRM drivers for i.mx6

[kruglikov_dmt]

Hi. I'm working with MCIMX6S5DVW10AC (IMX6 Solo). I noted that Linux kernel have two different DRM drivers:

* drivers/gpu/drm/vivante (also available in menuconfig as Vivante GCCore, selected for building and installation)

* drivers/gpu/drm/imx (not available in menuconfig)

What difference between these drivers?

Can you help me to check does DRM is enabled in my system (without X11)?

(I have troubles with application glmark2, it can't find any DRM devices in my system and fails with message "Failed to open DRM module 'imx-drm'").

Thanks!
