/** * @event: * * Optional pointer to a DRM event to signal upon completion of the * state update. The driver must send out the event when the atomic * commit operation completes. There are two cases: * * - The event is for a CRTC which is being disabled through this * atomic commit. In that case the event can be send out any time * after the hardware has stopped scanning out the current * framebuffers. It should contain the timestamp and counter for the * last vblank before the display pipeline was shut off. * * - For a CRTC which is enabled at the end of the commit (even when it * undergoes an full modeset) the vblank timestamp and counter must * be for the vblank right before the first frame that scans out the * new set of buffers. Again the event can only be sent out after the * hardware has stopped scanning out the old buffers. * * - Events for disabled CRTCs are not allowed, and drivers can ignore * that case. * * This can be handled by the drm_crtc_send_vblank_event() function, * which the driver should call on the provided event upon completion of * the atomic commit. Note that if the driver supports vblank signalling * and timestamping the vblank counters and timestamps must agree with * the ones returned from page flip events. With the current vblank * helper infrastructure this can be achieved by holding a vblank * reference while the page flip is pending, acquired through * drm_crtc_vblank_get() and released with drm_crtc_vblank_put(). * Drivers are free to implement their own vblank counter and timestamp * tracking though, e.g. if they have accurate timestamp registers in * hardware. * * For hardware which supports some means to synchronize vblank * interrupt delivery with committing display state there's also * drm_crtc_arm_vblank_event(). See the documentation of that function * for a detailed discussion of the constraints it needs to be used * safely. */ |

/** * @page_flip: * * Legacy entry point to schedule a flip to the given framebuffer. * * Page flipping is a synchronization mechanism that replaces the frame * buffer being scanned out by the CRTC with a new frame buffer during * vertical blanking, avoiding tearing (except when requested otherwise * through the DRM_MODE_PAGE_FLIP_ASYNC flag). When an application * requests a page flip the DRM core verifies that the new frame buffer * is large enough to be scanned out by the CRTC in the currently * configured mode and then calls the CRTC ->page_flip() operation with a * pointer to the new frame buffer. * * The driver must wait for any pending rendering to the new framebuffer * to complete before executing the flip. It should also wait for any * pending rendering from other drivers if the underlying buffer is a * shared dma-buf. * * An application can request to be notified when the page flip has * completed. The drm core will supply a struct &drm_event in the event * parameter in this case. This can be handled by the * drm_crtc_send_vblank_event() function, which the driver should call on * the provided event upon completion of the flip. Note that if * the driver supports vblank signalling and timestamping the vblank * counters and timestamps must agree with the ones returned from page * flip events.

For various reasons it can make sense to expose * more planes, crtcs or encoders than which are physically there. One * example is dual-pipe operations (which generally should be hidden * from userspace if when lockstepped in hardware, exposed otherwise), * where a plane might need 1 hardware plane (if it's just on one * pipe), 2 hardware planes (when it spans both pipes) or maybe even * shared a hardware plane with a 2nd plane (if there's a compatible * plane requested on the area handled by the other pipe). * * - Check that any transitional state is possible and that if * requested, the update can indeed be done in the vblank period * without temporarily disabling some functions. * * - Check any other constraints the driver or hardware might have. * * - This callback also needs to correctly fill out the &drm_crtc_state * in this update to make sure that drm_atomic_crtc_needs_modeset() * reflects the nature of the possible update and returns true if and * only if the update cannot be applied without tearing within one * vblank on that CRTC. The core uses that information to reject * updates which require a full modeset (i.e. blanking the screen, or * at least pausing updates for a substantial amount of time) if * userspace has disallowed that in its request. * * - The driver also does not need to repeat basic input validation * like done for the corresponding legacy entry points.
