Public Methods
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::CompleteCoordinatorConnection> CompleteCoordinatorConnection (::fdf::ClientEnd< ::fuchsia_hardware_display_engine::EngineListener> && engine_listener)Starts the information flow from the engine driver to the Coordinator.
Must be called exactly once, before all the other calls below.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::ImportBufferCollection> ImportBufferCollection (const ::fuchsia_hardware_display_engine::wire::BufferCollectionId & buffer_collection_id, ::fidl::ClientEnd< ::fuchsia_sysmem2::BufferCollectionToken> && collection_token)Sets up this driver to use a Sysmem BufferCollection.
Fails with ZX_ERR_INTERNAL if any error occurs during the setup process,
which mainly consists of communicating with the Sysmem service.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::ReleaseBufferCollection> ReleaseBufferCollection (const ::fuchsia_hardware_display_engine::wire::BufferCollectionId & buffer_collection_id)Releases the resources needed to use a Sysmem BufferCollection.
TODO(https://fxbug.dev/394954078): Make this method infallible.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::ImportImage> ImportImage (const ::fuchsia_hardware_display_types::wire::ImageMetadata & image_metadata, const ::fuchsia_hardware_display_engine::wire::BufferCollectionId & buffer_collection_id, uint32_t buffer_collection_index)Sets up the hardware to use a buffer as a display image data source.
Fails with ZX_ERR_SHOULD_WAIT if Sysmem reports that the
BufferCollection's buffers are not yet allocated. Fails with
ZX_ERR_INTERNAL if any other error occurs while obtaining the buffer
from the Sysmem service.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::ImportImageForCapture> ImportImageForCapture (const ::fuchsia_hardware_display_engine::wire::BufferCollectionId & buffer_collection_id, uint32_t buffer_collection_index)Sets up the hardware to use a buffer for display capture output.
This call must only be issued when the engine driver supports capture.
Capture support is reported in [`EngineInfo.is_capture_supported`]
returned by [`Engine.CompleteCoordinatorConnection`].
Fails with ZX_ERR_SHOULD_WAIT if Sysmem reports that the
BufferCollection's buffers are not yet allocated. Fails with
ZX_ERR_INTERNAL if any other error occurs while obtaining the buffer
from the Sysmem service.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::CheckConfiguration> CheckConfiguration (const ::fuchsia_hardware_display_engine::wire::DisplayConfig & display_config)Verifies that a configuration can be presented on a display.
The verification result must be valid for any configuration derived from
the given configuration.
A derived configuration can be obtained from another configuration by
applying one or more of the following operations. The list of operations
is expected to slowly grow over time.
* Replace an image ID with another image ID. The two IDs must identify
images that were imported with the same metadata.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::ApplyConfiguration> ApplyConfiguration (const ::fuchsia_hardware_display_engine::wire::DisplayConfig & display_config, const ::fuchsia_hardware_display_engine::wire::ConfigStamp & config_stamp)Submits a configuration for future presentation on a display.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::SetBufferCollectionConstraints> SetBufferCollectionConstraints (const ::fuchsia_hardware_display_types::wire::ImageBufferUsage & usage, const ::fuchsia_hardware_display_engine::wire::BufferCollectionId & buffer_collection_id)Conveys the display hardware's limitations on image buffers to sysmem.
Fails with ZX_ERR_INTERNAL if any error occurs while communicating with
the the Sysmem service.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::SetDisplayPowerMode> SetDisplayPowerMode (const ::fuchsia_hardware_display_types::wire::DisplayId & display_id, ::fuchsia_hardware_display_types::wire::PowerMode power_mode)Sets a display's power mode.
Returns `ZX_ERR_NOT_SUPPORTED` if the display driver or hardware does
not support the requested power mode.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::SetMinimumRgb> SetMinimumRgb (uint8_t minimum_rgb)Set the minimum value of RGB channels.
Fails with ZX_ERR_NOT_SUPPORTED if RGB clamping is not supported. Most
engine drivers are expected to fail in this manner.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::StartCapture> StartCapture (const ::fuchsia_hardware_display_engine::wire::ImageId & capture_image_id)Starts a display capture operation.
The engine driver must not be performing another capture operation. The
capture operation is considered to be in-progress from the moment when a
successful call to [`DisplayEngine.StartCapture`] is issued, until the
moment when the engine driver issues a call to
[`DisplayEngineListener.OnCaptureComplete`].
This call must only be issued when the engine driver supports capture.
Capture support is reported in [`EngineInfo.is_capture_supported`]
returned by [`Engine.CompleteCoordinatorConnection`].
This call must only be issued after a configuration has been applied to
the display.
Fails with ZX_ERR_IO_REFUSED if the display engine hardware failed to
start the capture. This error could point to a systemic issue, such as
the system having insufficient DRAM bandwidth to capture the currently
applied display configuration. This error could also be caused by a
temporary hardware failure.
Caller provides the backing storage for FIDL message.
::fidl::internal::WireBufferThenable< ::fuchsia_hardware_display_engine::Engine::ReleaseCapture> ReleaseCapture (const ::fuchsia_hardware_display_engine::wire::ImageId & capture_image_id)Releases resources for using a buffer for display capture output.
This call must only be issued when the engine driver supports capture.
Capture support is reported in [`EngineInfo.is_capture_supported`]
returned by [`Engine.CompleteCoordinatorConnection`].
