Specialized DataSink with dynamic partition tables.

Variants

ReadAsset

Reads the partition corresponding to configuration and asset into a vmo and returns it. The size field of the returned Buffer will be the size of just the asset, if it can be determined. Otherwise, it will be the size of the entire partition. The size and stream size of the vmo in the returned Buffer will always be the size of the entire partition.

Fields

configuration: Configuration

asset: Asset

responder: DynamicDataSinkReadAssetResponder

WriteAsset

Writes partition corresponding to configuration and asset with data from payload. payload may need to be resized to the partition size, so the provided vmo must have been created with ZX_VMO_RESIZABLE or must be a child VMO that was created with ZX_VMO_CHILD_RESIZABLE. Will zero out rest of the partition if payload is smaller than the size of the partition being written.

Returns ZX_ERR_INVALID_ARGS if configuration specifies active configuration.

Fields

configuration: Configuration

asset: Asset

payload: Buffer

responder: DynamicDataSinkWriteAssetResponder

WriteFirmware

Writes firmware data from payload.

configuration represents the A/B/R configuration. For platforms that do not support firmware A/B/R, the parameter will be ignored by the underlying device-specific logic .

type is a device-specific string identifying the payload contents, used to select the proper paving logic. For example, a device with multiple bootloader stages might send them as separate calls to WriteFirmware(), differentiated by type. An empty string indicates the default type.

payload may need to be resized to the partition size, so the provided vmo must have been created with ZX_VMO_RESIZABLE or must be a child VMO that was created with ZX_VMO_CHILD_RESIZABLE.

Fields

configuration: Configuration

type_: String

payload: Buffer

responder: DynamicDataSinkWriteFirmwareResponder

ReadFirmware

Read firmware corresponding to configuration and type.

Parameter configuration and type are the same as WriteFirmware.

If ReadFirmware returns error, caller should assume that firmware image does not exist or is in a bad state, or firmware read is not defined for the product.

Fields

configuration: Configuration

type_: String

responder: DynamicDataSinkReadFirmwareResponder

WriteVolumes

Writes FVM with data from streamed via payload. This potentially affects all configurations.

Fields

payload: ClientEnd<PayloadStreamMarker>

responder: DynamicDataSinkWriteVolumesResponder

WriteOpaqueVolume

Write a raw volume image to the device. The image will be passed as it is to the device partitioner backend to write. Therefore the format and write logic for the image is up to the product to define. It differs from WriteVolume(), which is specifically for writing the FVM sparse image, in that the paver will not perform any FVM related parsing or other operation of the image. Thus it is not dependent on the volume driver version and less susceptible to an outdated paver.

Returns ZX_ERR_NOT_SUPPORTED if the backend does not support opaque volume blobs.

Fields

payload: Buffer

responder: DynamicDataSinkWriteOpaqueVolumeResponder

WriteSparseVolume

Writes an image in the Android Sparse format. Identical in behaviour to WriteOpaqueVolume, except the contents of payload are parsed as a sparse image and unpacked before being written to disk.

Fields

payload: Buffer

responder: DynamicDataSinkWriteSparseVolumeResponder

Flush

Flush all previously buffered writes to persistent storage.

Fields

responder: DynamicDataSinkFlushResponder

InitializePartitionTables

Initializes partitions on given block device.

Currently only supported on devices which don’t support fastboot (which is the preferred mechanism for device setup).

WARNING: This API will wipe the existing partitions and data loss may occur. Non-Fuchsia partitions may be preserved, although this is behaviour is board-specific.

Fields

responder: DynamicDataSinkInitializePartitionTablesResponder

WipePartitionTables

Wipes all entries from the partition table of the specified block device. Currently only supported on devices with a GPT.

WARNING: This API may destructively remove non-fuchsia maintained partitions from the block device.

Fields

responder: DynamicDataSinkWipePartitionTablesResponder
