<587DD4E3.5070202@rock-chips.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.

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.
