struct DeviceState - common device state, accessed with qdev helpers

This structure should not be accessed directly. We declare it here so that it can be embedded in individual device state structures.

Fields

parent_obj: Object

id: *mut c_char

@id: global device id

canonical_path: *mut c_char

@canonical_path: canonical path of realized device in the QOM tree

realized: bool

@realized: has device been realized?

pending_deleted_event: bool

@pending_deleted_event: track pending deletion events during unplug

pending_deleted_expires_ms: i64

@pending_deleted_expires_ms: optional timeout for deletion events

hotplugged: c_int

@hotplugged: was device added after PHASE_MACHINE_READY?

allow_unplug_during_migration: bool

@allow_unplug_during_migration: can device be unplugged during migration

parent_bus: *mut BusState

@parent_bus: bus this device belongs to

gpios: NamedGPIOListHead

@gpios: QLIST of named GPIOs the device provides.

clocks: NamedClockListHead

@clocks: QLIST of named clocks the device provides.

child_bus: BusStateHead

@child_bus: QLIST of child buses

num_child_bus: c_int

@num_child_bus: number of @child_bus entries

instance_id_alias: c_int

@instance_id_alias: device alias for handling legacy migration setups

alias_required_for_version: c_int

@alias_required_for_version: indicates @instance_id_alias is needed for migration

reset: ResettableState

@reset: ResettableState for the device; handled by Resettable interface.

unplug_blockers: *mut GSList

@unplug_blockers: list of reasons to block unplugging of device

mem_reentrancy_guard: MemReentrancyGuard

@mem_reentrancy_guard: Is the device currently in mmio/pio/dma?

Used to prevent re-entrancy confusing things.

Trait Implementations
