| 517 | * |
| 518 | * Legacy entry point to schedule a flip to the given framebuffer. |
| 519 | * |
| 520 | * Page flipping is a synchronization mechanism that replaces the frame |
| 521 | * buffer being scanned out by the CRTC with a new frame buffer during |
| 522 | * vertical blanking, avoiding tearing (except when requested otherwise |
| 523 | * through the DRM_MODE_PAGE_FLIP_ASYNC flag). When an application |
| 524 | * requests a page flip the DRM core verifies that the new frame buffer |
| 525 | * is large enough to be scanned out by the CRTC in the currently |
| 526 | * configured mode and then calls the CRTC ->page_flip() operation with a |
| 527 | * pointer to the new frame buffer. |
| 528 | * |
| 529 | * The driver must wait for any pending rendering to the new framebuffer |
| 530 | * to complete before executing the flip. It should also wait for any |
| 531 | * pending rendering from other drivers if the underlying buffer is a |
| 532 | * shared dma-buf. |
| 533 | * |
| 534 | * An application can request to be notified when the page flip has |
| 535 | * completed. The drm core will supply a struct &drm_event in the event |
| 536 | * parameter in this case. This can be handled by the |
| 537 | * drm_crtc_send_vblank_event() function, which the driver should call on |
| 538 | * the provided event upon completion of the flip. Note that if |
| 539 | * the driver supports vblank signalling and timestamping the vblank |
| 540 | * counters and timestamps must agree with the ones returned from page |
| 541 | * flip events. With the current vblank helper infrastructure this can |
| 542 | * be achieved by holding a vblank reference while the page flip is |
| 543 | * pending, acquired through drm_crtc_vblank_get() and released with |
| 544 | * drm_crtc_vblank_put(). Drivers are free to implement their own vblank |
| 545 | * counter and timestamp tracking though, e.g. if they have accurate |
| 546 | * timestamp registers in hardware. |
| 547 | * |
| 548 | * FIXME: |
| 549 | * |
| 550 | * Up to that point drivers need to manage events themselves and can use |
| 551 | * even->base.list freely for that. Specifically they need to ensure |

| 563 | * block (but not reject) any rendering to the old framebuffer until the |
| 564 | * flip operation has completed and the old framebuffer is no longer |
| 565 | * visible. This requirement has been lifted, and userspace is instead |
| 566 | * expected to request delivery of an event and wait with recycling old |
| 567 | * buffers until such has been received. |

| 571 | * 0 on success or a negative error code on failure. Note that if a |

| 2148 | * This is the only hook to validate an atomic modeset update. This |

| 2150 | * or driver doesn't support. This includes but is of course not limited |
| 2151 | * to: |
| 2152 | * |
| 2153 | * - Checking that the modes, framebuffers, scaling and placement |
| 2154 | * requirements and so on are within the limits of the hardware. |
| 2155 | * |
| 2156 | * - Checking that any hidden shared resources are not oversubscribed. |
| 2157 | * This can be shared PLLs, shared lanes, overall memory bandwidth, |
| 2158 | * display fifo space (where shared between planes or maybe even |
| 2159 | * CRTCs). |
| 2160 | * |
| 2161 | * - Checking that virtualized resources exported to userspace are not |
| 2162 | * oversubscribed. For various reasons it can make sense to expose |
| 2163 | * more planes, crtcs or encoders than which are physically there. One |
| 2164 | * example is dual-pipe operations (which generally should be hidden |
| 2165 | * from userspace if when lockstepped in hardware, exposed otherwise), |
| 2166 | * where a plane might need 1 hardware plane (if it's just on one |
| 2167 | * pipe), 2 hardware planes (when it spans both pipes) or maybe even |
| 2168 | * shared a hardware plane with a 2nd plane (if there's a compatible |
| 2169 | * plane requested on the area handled by the other pipe). |
| 2170 | * |
| 2171 | * - Check that any transitional state is possible and that if |
| 2172 | * requested, the update can indeed be done in the vblank period |
| 2173 | * without temporarily disabling some functions. |
| 2174 | * |
| 2175 | * - Check any other constraints the driver or hardware might have. |
| 2176 | * |
| 2177 | * - This callback also needs to correctly fill out the &drm_crtc_state |
| 2178 | * in this update to make sure that drm_atomic_crtc_needs_modeset() |
| 2179 | * reflects the nature of the possible update and returns true if and |
| 2180 | * only if the update cannot be applied without tearing within one |
| 2181 | * vblank on that CRTC. The core uses that information to reject |
| 2182 | * updates which require a full modeset (i.e. blanking the screen, or |
| 2183 | * at least pausing updates for a substantial amount of time) if |
| 2184 | * userspace has disallowed that in its request. |
| 2185 | * |
| 2186 | * - The driver also does not need to repeat basic input validation |
| 2187 | * like done for the corresponding legacy entry points. The core does |
| 2188 | * that before calling this hook. |
| 2189 | * |

| 2191 | * error conditions which don't have to be checked at the |
| 2192 | * ->atomic_check() stage? |

| 2195 | * an atomic modeset update is described. |
