Does opengl conform test support GBM?

hi all,

I have a linux system with kernel + busybox, without window/desktop system.

I have setup egl mesa + gpu vendor driver.
and written a simple egl+drm test case to draw a tri-angle, and it succeeds.

Now I want to run opengl-cts to have complete test, what shall I do?

  1. does opengl-cts support egl+drm?
    seems option “--deqp-egl-display-type=gbm” doesn’t work.

  2. is there any other solution to test over linux without window system?

thanks
Leon
