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

2019-06-09T07:16:17+00:00

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

2019-02-22T11:17:58+00:00

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

2019-02-22T11:17:58+00:00

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

2019-02-22T11:17:54+00:00

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

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.
