2018-07-30drm/armada: remove unnecessary armada_plane structureRussell King
We no longer require a private armada_plane structure, so eliminate it, and use the drm_plane structure directly. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: update planes after the dumb frame is completeRussell King
Write out the plane updates after the dumb frame has completed, but just before the blank period. This allows all the plane updates to be performed in a flicker-free non-tearing manner. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: switch overlay plane to atomic modesetRussell King
Switch the overlay plane away from the transitional helpers and legacy methods, and use atomic helpers instead to implement the legacy set_plane ioctl methods. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: switch primary plane to atomic modesetRussell King
Switch the primary plane away from the transitional helpers, and use the atomic helpers instead to implement the legacy set_plane ioctl call for this plane. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: switch legacy modeset to atomic modesetRussell King
Switch the legacy set_config() method to use the atomic modeset helper, which allows us to get rid of the legacy dpms, prepare, commit, mode_set, mode_set_base and disable helper methods. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: enable atomic modeset supportRussell King
Enable atomic modeset helpers, and internal DRM use of atomic modeset with armada-drm. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: implement atomic_enable()/atomic_disable() methodsRussell King
Implement the atomic_enable()/atomic_disable() methods used by the atomic modeset helpers. atomic_disable() will need some transitional code during conversion to ensure proper ordering is maintained. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: unhook dpms state from armada_drm_crtc_update()Russell King
Explicitly pass in the desired enable/disable state into armada_drm_crtc_update() rather than having it use the DPMS state stored in our crtc structure. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: push responsibility for clock management to backendRussell King
Push responsibility for managing the clock during DPMS down into the variant backend, rather than the CRTC layer having knowledge of its state. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: handle atomic modeset crtc eventsRussell King
Prepare handling for atomic modeset CRTC events. Currently, using the transition helpers, CRTC events do not exist, but once we switch to proper atomic modeset, they have to be handled. We queue an event for the next vblank in two places: - armada_drm_crtc_atomic_flush() provided we aren't doing an atomic modeset. - armada_drm_crtc_commit() if we are committing a modeset. This ensures that the event is sent at the correct time (after all updates have been written to the hardware and after the following vblank.) Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: clean up SPU_ADV_REGRussell King
Rather than writing all bits of SPU_ADV_REG on modeset, only write what we need to change, and initialise the register in the variant initialisation. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: update debug in armada_drm_crtc_mode_set_nofb()Russell King
Update debug to use KMS level, and print the mode using the standard format for mode lines, but print the adjusted CRTC parameters as that's what we will be programming for. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: move sync signal polarity to mode_set_nofb() methodRussell King
For atomic modeset, we need to set the sync signal polarities from the CRTC state structure rather than the legacy mode structure stored in CRTC. In any case, we should update this from our mode_set_nofb() method, rather than the commit() method. Move it there, and ensure that armada_drm_crtc_update() will not overwrite these bits. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: remove crtc YUV colourspace propertiesRussell King
Remove the unused CRTC colourspace properties - userspace does not make use of these. In any case, these are not a property of the CRTC, since they demonstrably only affect the video (overlay) plane, irrespective of the format of the graphics (primary) plane. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: move primary plane to separate fileRussell King
Split out the primary plane support; this is now entirely separate from the CRTC support. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: use old_state for update tracking in atomic_update()Russell King
Rather than tracking the register state, we can now check the previous state and decide which registers need updating from that since the old plane state indicates the previous state which was programmed into the hardware. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: remove temporary crtc stateRussell King
Now that we have the CRTC using the atomic modeset transitional helper, there is no need to build a temporary crtc state anymore - we can use the CRTC atomic state directly. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: convert overlay plane to atomic stateRussell King
The overlay plane support updates asynchronously to the request, but the drm_plane_helper_update() transitional helper waits for a vblank event before releasing the framebuffer. Using the transitional helper would make the call block, which would introduce a performance regression. Convert the overlay plane update to use the atomic state structures and methods for the plane, but implement our own legacy update method rather than the transitional helper. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: convert page_flip to use primary plane atomic_update()Russell King
page_flip requests happen asynchronously, so we can't wait on the vblank event before returning to userspace, as the transitional plane update helper would do. Craft our own implementation that keeps the asynchronous behaviour of this request, while making use of the atomic infrastructure for the primary plane update. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: convert primary plane to atomic stateRussell King
Convert the primary plane as a whole to use its atomic state and the transitional helpers. The CRTC is also switched to use the transitional helpers for mode_set() and mode_set_base(). Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: merge armada_drm_gra_plane_regs() into only callerRussell King
armada_drm_gra_plane_regs() is now only ever called from within armada_drm_primary_update_state(), so merge it into this function. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: use core of primary update_plane for mode setRussell King
Use the core of the update_plane method to configure the primary plane within mode_set() rather than duplicating this code. This moves us closer to the same code structure that the atomic modeset transitional helpers will use. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: move mode set vblank handling and disable/enableRussell King
Move the mode set vblank handling and controller enable/disable to the prepare() and commit() callbacks. This will be needed when we move to mode_set_nofb() as we should not enable the controller without the plane coordinates and location having been properly updated. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: add rectangle helpersRussell King
Add helpers to convert rectangle width/height and x/y to register values. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-30drm/armada: clean up armada_drm_crtc_page_flip()Russell King
drm_mode_page_flip_ioctl() already takes care of checking the framebuffer format, and also assigns primary->fb after a successful call to this handler. These are both redundant, and can be removed. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2018-07-09drm/armada: fix irq handlingRussell King
Add the missing locks to the IRQ enable/disable paths, and fix a comment in the interrupt handler: reading the ISR clears down the status bits, but does not reset the interrupt so it can signal again. That seems to require a write. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2018-03-05drm/armada: Use drm_mode_get_hv_timing() to populate plane clip rectangleVille Syrjälä
Use drm_mode_get_hv_timing() to fill out the plane clip rectangle. Since armada isn't atomic we'll use crtc->enabled and crtc->mode instead of the stuff under crtc_state. Once everyone agrees on how the clip rectangle gets set up we can move the code into drm_atomic_helper_check_plane_state().

2018-03-05drm/armada: Construct a temporary crtc state for plane checksVille Syrjälä
As armada isn't an atomic driver trying to pass a non-populated crtc->state to drm_atomic_helper_check_plane_state() will end in tears. Construct a temporary crtc state a la drm_plane_helper_check_update() and pass that instead. For now we just really need crtc_state->enable to be there.

git://git.armlinux.org.uk/~rmk/linux-arm into drm-next This series builds upon the set of fixes previously submitted to move Armada DRM closer to atomic modeset. We're nowhere near yet, but this series helps to get us closer by unifying some of the differences between the primary and overlay planes. New features added allows userspace to disable the primary plane if overlay is full screen and there's nothing obscuring the colorkey - this saves having to fetch an entire buffer containing nothing but colorkey when displaying full screen video.

2017-12-08drm/armada: implement primary plane updateRussell King
Implement primary plane update without having to go through a modeset to achieve that; the hardware does not require such complexity. This means we treat the primary plane as any other, allowing the format, size, position and scaling to be updated via the normal plane ioctls. This also allows us to seemlessly disable and re-enable the primary plane when (eg) displaying full-frame video without any graphic clipping the overlaid video - which saves wasting memory bandwidth needlessly verifying that the colorkey is indeed filling the entire primary plane.

2017-12-08drm/armada: extract register generation from armada_drm_primary_set()Russell King

2017-12-08drm/armada: disable planes at next blanking periodRussell King
Disable planes at the next blanking period rather than immediately. In order to achieve this, we need to delay the clearing of dcrtc->plane until after the next blanking period, so move that into a separate work function. To avoid races, we also need to move its assignment in the overlay code. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2017-12-08drm/armada: allow armada_drm_plane_work_queue() to silently failRussell King
Avoid printing an error message when armada_drm_plane_work_queue() is unable to get the vblank (eg, because we're doing a modeset.) Continue to report the failure to the caller, so the caller can handle this. Move the error message into armada_ovl_plane_update(). Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: only enable HSMOOTH if scaling horizontallyRussell King
Only enable the HSMOOTH control bit if we are scaling horizontally, otherwise it makes no sense to enable the horizontal scaler. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move writes of LCD_SPU_SRAM_PARA1 under lockRussell King
Move writes of LCD_SPU_SRAM_PARA1 under the irq lock, so that we can add this to the frame updates at interrupt time when disabling a plane. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move regs into armada_plane_workRussell King

2017-12-08drm/armada: move fb retirement into armada_plane_workRussell King
Both the primary and overlay planes retire framebuffers in a similar manner; this can be consolidated by moving the retirement up to the armada_plane_work layer. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move overlay plane work out from under spinlockRussell King
Move the overlay plane work out from under the spinlock so that both the primary and overlay planes run their work in the same context. This is necessary so that we can use frame works with the overlay plane. However, we must update the CRTC registers under the spinlock, so fix up the overlay code for that.

2017-12-08drm/armada: store plane in armada_plane_workRussell King

2017-12-08drm/armada: remove armada_drm_plane_work_cancel() return valueRussell King
