* or driver doesn't support. This includes but is of course not limited |
|
* to: |
|
* |
|
* - Checking that the modes, framebuffers, scaling and placement |
|
* requirements and so on are within the limits of the hardware. |
|
* |
|
* - Checking that any hidden shared resources are not oversubscribed. |
|
* This can be shared PLLs, shared lanes, overall memory bandwidth, |
|
* display fifo space (where shared between planes or maybe even |
|
* CRTCs). |
|
* |
|
* - Checking that virtualized resources exported to userspace are not |
|
* oversubscribed. 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. The core does |
|
* that before calling this hook. |
|
* |
|
* See the documentation of @atomic_commit for an exhaustive list of |
|
* error conditions which don't have to be checked at the in this |

* callback. |

* See the documentation for &struct drm_atomic_state for how exactly |
|
* an atomic modeset update is described. |

|
* &drm_modeset_lock through drm_modeset_lock(). |
|
* |
|
* - -ENOMEM, if allocating additional state sub-structures failed due |
|
* to lack of memory. |
|
* |
|
* - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted. |
|
* This can either be due to a pending signal, or because the driver |
|
* needs to completely bail out to recover from an exceptional |
|

|
* |
|

* specifically committing the update to the hardware, should be done |
|
* without blocking the caller. For updates which do not require a |
|
* modeset this must be guaranteed. |
|
* |
|
* The driver must wait for any pending rendering to the new |
|
* framebuffers 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. Nonblocking commits must not wait for |
|
* rendering in the context of this callback. |
|
* |
|
* An application can request to be notified when the atomic commit has |
|
* completed. These events are per-CRTC and can be distinguished by the |
|
* CRTC index supplied in &drm_event to userspace. |
|
* |
|
* The drm core will supply a &struct drm_event in each CRTC's |
|
* &drm_crtc_state.event. See the documentation for |

* &drm_crtc_state.event for more details about the precise semantics of |
|
* this event. |
|
* |
|
* NOTE: |
|
* |
|
* Drivers are not allowed to shut down any display pipe successfully |
|
* enabled through an atomic commit on their own. Doing so can result in |
|
* compositors crashing if a page flip is suddenly rejected because the |
|
* pipe is off. |
|
* |
|
* RETURNS: |
|
* |
|
* 0 on success or one of the below negative error codes: |
|
* |
|
* - -EBUSY, if a nonblocking updated is requested and there is |
|
* an earlier updated pending. Drivers are allowed to support a queue |
|
* of outstanding updates, but currently no driver supports that. |
|
* Note that drivers must wait for preceding updates to complete if a |
|
* synchronous update is requested, they are not allowed to fail the |
|
* commit in that case. |
|
* |
|
* - -ENOMEM, if the driver failed to allocate memory. Specifically |
|
* this can happen when trying to pin framebuffers, which must only |
|
* be done when committing the state. |
|
* |
|
* - -ENOSPC, as a refinement of the more generic -ENOMEM to indicate |
|
* that the driver has run out of vram, iommu space or similar GPU |
|
* address space needed for framebuffer. |
|
* |
|
* - -EIO, if the hardware completely died. |
|
* |
|
* - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted. |
|
* This can either be due to a pending signal, or because the driver |
|
* needs to completely bail out to recover from an exceptional |
|
* situation like a GPU hang. From a userspace point of view all errors are |
|
* treated equally. |
|
* |
|
* This list is exhaustive. Specifically this hook is not allowed to |
