drm/imx: only send event on crtc disable if kept disabled

2019-07-10T07:52:31Z

commit 5aeab2bfc9ffa72d3ca73416635cb3785dfc076f upstream. The event will be sent as part of the vblank enable during the modeset if the crtc is not being kept disabled.

drm/imx: notify drm core before sending event during crtc disable

2019-07-10T07:52:30Z

commit 78c68e8f5cd24bd32ba4ca1cdfb0c30cf0642685 upstream. Notify drm core before sending pending events during crtc disable. This fixes the first event after disable having an old stale timestamp by having drm_crtc_vblank_off update the timestamp to now. This was seen while debugging weston log message: Warning: computed repaint delay is insane: -8212 msec This occurred due to: 1. driver starts up 2. fbcon comes along and restores fbdev, enabling vblank 3. vblank_disable_fn fires via timer disabling vblank, keeping vblank seq number and time set at current value (some time later) 4. weston starts and does a modeset 5. atomic commit disables crtc while it does the modeset 6. ipu_crtc_atomic_disable sends vblank with old seq number and time Fixes: a474478642d5 ("drm/imx: fix crtc vblank state regression") Signed-off-by: Robert Beckett Reviewed-by: Daniel Vetter Signed-off-by: Philipp Zabel Signed-off-by: Greg Kroah-Hartman

drm/imx: ipuv3-plane: fix atomic update status query for non-plus i.MX6Q

2019-06-09T07:16:17Z

commit 137caa702f2308f7ef03876e164b0d0f3300712a upstream. The current buffer check halves the frame rate on non-plus i.MX6Q, as the IDMAC current buffer pointer is not yet updated when ipu_plane_atomic_update_pending is called from the EOF irq handler.

drm/imx: handle pending updates better, add plane zpos property support - Add a mechanism to only send commit done events once all pending updates have been applied. This closes a small race window where already armed events could fire even though the double buffered hardware update just missed the update window. - Add plane zpos property support to allow placing the overlay plane behind the primary plane. - Allow building imx-drm on all platforms under COMPILE_TEST.

drm/imx: only send commit done event when all state has been applied

2019-02-22T11:17:58Z

Currently there is a small race window where we could manage to arm the vblank event from atomic flush, but programming the hardware was too close to the frame end, so the hardware will only apply the current state on the next vblank. In this case we will send out the commit done event too early causing userspace to reuse framebuffes that are still in use. Instead of using the event arming mechnism, just remember the pending event and send it from the vblank IRQ handler, once we are sure that all state has been applied successfully.

drm/imx: imx-tve: depend on COMMON_CLK

2019-02-22T11:17:58Z

Since the TVE provides a clock to the DI, the driver can only be compiled if the common clock framework is enabled. With the COMMON_CLK dependency in place, it will be possible to allow building the other parts of imx-drm under COMPILE_TEST on architectures that do not select the common clock framework.

drm/imx: ipuv3-plane: add zpos property

2019-02-22T11:17:54Z

Add a zpos property to planes. Call drm_atomic_helper_check() instead of calling drm_atomic_helper_check_modeset() and drm_atomic_check_planes() manually. This effectively adds a call to drm_atomic_normalize_zpos() before checking planes. Reorder atomic update to allow changing plane zpos without modeset. Note that the initial zpos is set in ipu_plane_state_reset(). The initial value set in ipu_plane_init() is just for show. The zpos parameter of drm_plane_create_zpos_property() is ignored because the newly created plane do not have state yet. Signed-off-by: Philipp Zabel Tested-by: Marius Vlad
