Protocol for types which need to implement both Partition and fuchsia.device.Controller.

Variants

GetInfo

Fields

responder: PartitionAndDeviceGetInfoResponder

Get information about the underlying block device.

GetStats

Fields

clear: bool

responder: PartitionAndDeviceGetStatsResponder

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: PartitionAndDeviceControlHandle

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

ReadBlocks

Fields

vmo: Vmo

length: u64

dev_offset: u64

vmo_offset: u64

responder: PartitionAndDeviceReadBlocksResponder

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: PartitionAndDeviceWriteBlocksResponder

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: PartitionAndDeviceGetTypeGuidResponder

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: PartitionAndDeviceGetInstanceGuidResponder

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: PartitionAndDeviceGetNameResponder

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

ConnectToDeviceFidl

Fields

server: Channel

control_handle: PartitionAndDeviceControlHandle

Connect to the underlying device’s FIDL protocol. This connection will not be multiplexed with fuchsia.device.Controller or fuchsia.io.Node.

Bind

Fields

driver: String

responder: PartitionAndDeviceBindResponder

Attempt to bind a driver to this device.

• request driver This represents the suffix of a driver URL (e.g: “fvm.cm”). If this is non-empty, then the only drivers that will try to bind are ones that match this url suffix.

Rebind

Fields

driver: String

responder: PartitionAndDeviceRebindResponder

Unbind all the children of this device, and then attempt to bind a driver to the device. This will not return until the bind completes.

• request driver This represents the suffix of a driver URL (e.g: “fvm.cm”). If this is non-empty, then the only drivers that will try to bind are ones that match this url suffix.

UnbindChildren

Fields

responder: PartitionAndDeviceUnbindChildrenResponder

This api will unbind all the children of this device synchronously. This will avoid watching for device removal by the clients.

ScheduleUnbind

Fields

responder: PartitionAndDeviceScheduleUnbindResponder

Disconnect this device and allow its parent to be bound again. This may not complete before it returns.

GetTopologicalPath

Fields

responder: PartitionAndDeviceGetTopologicalPathResponder

Return the topological path for this device

GetMinDriverLogSeverity

Fields

responder: PartitionAndDeviceGetMinDriverLogSeverityResponder

Return the current logging flags for this device’s driver

SetMinDriverLogSeverity

Fields

severity: LogLevelFilter

responder: PartitionAndDeviceSetMinDriverLogSeverityResponder

Set the logging flags for this device’s driver.

GetCurrentPerformanceState

Fields

responder: PartitionAndDeviceGetCurrentPerformanceStateResponder

Gets the current performance state of the device.

SetPerformanceState

Fields

requested_state: u32

responder: PartitionAndDeviceSetPerformanceStateResponder

Set the performance state of this device to the requested performance state. This is only called for the current device and none of the descendants are aware of the state transition. Returns ZX_OK, if the device is in a working state and the performance state is changed to requested_state successfully. out_state will be same as requested_state. Returns error status, if switching to the requested_state was unsuccessful. out_state is the state that the device is currently in.
