Hello:
   I want to enable the video output at RK3288 Firefly board, but I 
found if I enable CONFIG_DRM_FBDEV_EMULATION, the HDMI would crash down 
sometimes but sometimes it works. After disable that opinion, I never 
meet a problem. I have not verified it with eDP as I meet a big problem 
in there.

static void vop_plane_atomic_update(struct drm_plane *plane,
         struct drm_plane_state *old_state)
{
     if (WARN_ON(!vop->is_enabled))
         return;

The issues seems vop is not enable. but commit planes is using 
DRM_PLANE_COMMIT_ACTIVE_ONLY...

Hi Randy

Can you add some print for this bug:
     1, I think vop_crtc_enable function should be call before 
vop_plane_atomic_update, you can add some print to verified it.
     2, also add a trace on vop_crtc_disable.
     3, print the status of  crtc->state->active and 
plane_crtc_active(plane->state) when bug happen.

Thanks.
