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.
