DRM page flip vblank events requested by page flips or atomic commits are created by the DRM core and then passed to driver through CRTC states (for atomic commit) or directly to the page flip handler (for legacy page flips). The events are then kept aside until the page flip completes, at which point drivers queue them for delivery with a call to drm_send_vblank_event(). When a DRM file handle is closed events pending for delivery are cleaned up automatically by the DRM core. Events that have been passed to the driver but haven't completed yet, however, are not handled by the DRM core. Drivers are responsible for destroying them and must not attempt to queue them for delivery. This is usually handled by drivers' preclose() handlers that cancel and destroy page flip events that reference the file handle being closed. With asynchronous atomic updates the story becomes more complex. Several asynchronous atomic updates can be pending, each of them carrying per-CRTC events. As the atomic_commit() operation doesn't receive a file handle context, drivers can't know which file handle a pending update refers to, making it difficult to cancel or wait for completion of updates related to the file handle being closed. It should be noted that cancelling page flips or waiting for atomic updates completion isn't required by the DRM core when closing a file handle. The only requirement is that no event gets queued for delivery after the preclose() operation returns. This can easily be achieved by storing events for atomic commits in a list, unlinking events from the file handle being closed by setting the file_priv field to NULL, and skipping delivery of unlinked events. This logic replaces the page flip cancellation completely. Signed-off-by:

When performing asynchronous atomic updates the modeset lock isn't taken around the callers of omap_crtc_flush(). This isn't an issue though, as access to the CRTC is properly serialized. Just drop the warning. Signed-off-by:

The field tracks the plane state to avoid double-enable or -disable. This isn't required anymore, as - the DRM atomic core guarantees that the plane atomic_update and atomic_disable functions will never be called on an enabled/disabled plane - the CRTC enable/disable operations that enable/disable the plane are already guarded against double enable/disable We can thus remove the enabled field completely. The omap_plane_set_enable() function then becomes a wrapper around omap_plane_setup() which can be called directly. Signed-off-by:

Allow setting up plane properties atomically using the plane set_property atomic helper. The properties are now stored in the plane state (requiring subclassing it) and applied when updating the planes. The CRTC exposes the properties of its primary plane for legacy reason. We can't get rid of that API, so simply delegate it to the primary plane. Signed-off-by:

Since the removal of omap_plane_mode_set(), framebuffers are now pinned exclusively through the plane .prepare_fb() and .cleanup_fb() operations as the remaining callers of omap_plane_setup() don't modify the framebuffer. Remove the manual pin/unpin infrastructure. Signed-off-by:

Use the new CRTC atomic transitional helpers drm_helper_crtc_mode_set() and drm_helper_crtc_mode_set_base() to implement the CRTC .mode_set and .mode_set_base operations. This delegates primary plane configuration to the plane .atomic_update and .atomic_disable operations, removing duplicate code from the CRTC implementation. Signed-off-by:

Hook up the default .reset(), .atomic_duplicate_state() and .atomic_free_state() helpers to ensure that state objects are properly created and destroyed, and call drm_mode_config_reset() at init time to create the initial state objects. Framebuffer reference count also gets maintained automatically by the transitional helpers except for the legacy page flip operation. Maintain it explicitly there. Signed-off-by:

When using atomic updates the CRTC .enable() and .disable() helper operations are preferred over the (then legacy) .prepare() and .commit() operations. Implement .enable() and rework .disable() to not depend on DPMS, easing DPMS removal later on. Signed-off-by:

We can't rely on crtc->primary->fb in the page flip worker, as a racing CRTC disable (due for instance to an explicit framebuffer deletion from userspace) would set that field to NULL before the worker gets a change to run. Store the framebuffer queued for page flip in a new field of omap_crtc instead, and hold a reference to it. Signed-off-by:

The DRM core vblank handling mechanism requires drivers to forcefully turn vblank reporting off when disabling the CRTC, and to restore the vblank reporting status when enabling the CRTC. Implement this using the drm_crtc_vblank_on/off helpers. When disabling vblank we must first wait for page flips to complete, so implement page flip completion wait as well. Finally, drm_crtc_vblank_off() must be called at startup to synchronize the state of the vblank core code with the hardware, which is initially disabled. An interesting side effect is that the .disable_vblank() operation will now be called for the first time with the CRTC disabled and the DISPC runtime suspended. The dispc_runtime_get() call in .disable_vblank() is supposed to take care of that, but the operation is called with a spinlock held, which prevents it from sleeping. To fix that move DISPC runtime PM handling out of the vblank operations to the CRTC code, ensuring that the display controller will always be powered when enabling or disabling vblank interrupts.

To implement proper vblank control the driver will need to wait for page flip completion before disabling the vblank interrupt. This is made complex by the page flip implementation which queues and submits page flips to the hardware in two separate steps between which DRM locks are released. We thus need to avoid waiting on a page flip that has been queued but not submitted as submission and wait are covered by the same lock. Rework page flip handling as a first step by splitting the flip_pending boolean variable into an enumerated state and moving between states based on flip queue, submission and completion. The CANCELLED state will be used in a second step. Signed-off-by:

Pending page flips must be cancelled when closing the device, otherwise their completion at next vblank will result in nasty effects, including possible oopses due to resources required to complete the page flip being freed. Signed-off-by:

The omapdrm can't use drm_irq_install() and drm_irq_uninstall() as it delegates IRQ handling to the omapdss driver. However, the code still declares IRQ-related operations used by the DRM IRQ helpers, and calls them indirectly. Simplify the implementation by calling the functions directly or inlining them. The irq_enabled checks can then also be simplified as the call stacks guarantees that omap_drm_irq_install() and omap_drm_irq_uninstall() will never run concurrently. Signed-off-by:

The omapdrm driver implements a mechanism to apply new settings (due to plane update, plane disable, plane property set, CRTC mode set or CRTC DPMS) asynchronously. While this improves performance, it adds a level of complexity that makes transition to the atomic update API close to impossible. Furthermore the atomic update API requires part of the apply operations to be synchronous (such as pinning the framebuffers), so the current implementation needs to be changed. Simplify the CRTC and plane code by making updates synchronous to prepare for the switch to the atomic update API. Asynchronous update will be implemented in a second step. Signed-off-by:
