}

Defines access to a device which is accessible in block-granularity chunks for reading and writing.

Variants

GetInfo

Get information about the underlying block device.

Fields

responder: BlockGetInfoResponder

GetStats

Returns stats about block device operations. Setting clear will reset stats counters.

Fields

clear: bool

responder: BlockGetStatsResponder

OpenSession

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

Fields

session: ServerEnd<SessionMarker>

control_handle: BlockControlHandle

ReadBlocks

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.

Fields

vmo: Vmo

length: u64

dev_offset: u64

vmo_offset: u64

responder: BlockReadBlocksResponder

WriteBlocks

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.

Fields

vmo: Vmo

length: u64

dev_offset: u64

vmo_offset: u64

responder: BlockWriteBlocksResponder
