Partition describes a region of one or more block devices, labelled with distinguishing identifiers.

Variants

GetInfo

Fields

responder: PartitionGetInfoResponder

Get information about the underlying block device.

GetStats

Fields

clear: bool

responder: PartitionGetStatsResponder

Returns stats about the block device on the provided buffer and optionally clears the counters.

storage_metrics.CallStat.bytes_transferred is number of bytes requested to be transferred.

OpenSession

Fields

session: ServerEnd<SessionMarker>

control_handle: PartitionControlHandle

Opens a new FIFO-based session on the block device.

ReadBlocks

Fields

vmo: Vmo

length: u64

dev_offset: u64

vmo_offset: u64

responder: PartitionReadBlocksResponder

Reads from a block device.

This read does not require exclusive access. length, dev_offset and vmo_offset are specified in bytes, but they must be block-aligned. This method is provided for backward compatibility, and is not intended for new code. New code should use the FIFO interface along with the client libraries to read and write from block devices.

WriteBlocks

Fields

vmo: Vmo

length: u64

dev_offset: u64

vmo_offset: u64

responder: PartitionWriteBlocksResponder

Writes to a block device.

This write does not require exclusive access. length, dev_offset and vmo_offset are specified in bytes, but they must be block-aligned. This method is provided for backward compatibility, and is not intended for new code. New code should use the FIFO interface along with the client libraries to read and write from block devices.

GetTypeGuid

Fields

responder: PartitionGetTypeGuidResponder

Gets the type GUID of the partition (if one exists). If the partition has no type GUID, ZX_ERR_NOT_SUPPORTED is returned.

GetInstanceGuid

Fields

responder: PartitionGetInstanceGuidResponder

Gets the instance GUID of the partition (if one exists). If the partition has no instance GUID, ZX_ERR_NOT_SUPPORTED is returned.

GetName

Fields

responder: PartitionGetNameResponder

Gets the name of the partition (if one exists). If the partition has no name, ZX_ERR_NOT_SUPPORTED is returned.
