vdev_s

Virtual device (vdev) information

Synopsis:

#include <qvm/vdev-core.h>

struct vdev_s {
    void* v_device;
    struct vdev_factory* v_factory;
    struct guest_system* v_gsp;
    struct qvm_state_block v_block;
    struct guest_intr v_intr;
    pthread_mutex_t v_mtx;
    struct qvm_sched_info v_sched;
} ;

Data:

void* v_device: A pointer to device-specific state information.
struct vdev_factory* v_factory: A pointer to the device factory for the vdev.
struct guest_system* v_gsp: A pointer to the guest system in which the vdev is defined (the hosting qvm process instance).
struct qvm_state_block v_block: The location of the vdev in the guest system.
struct guest_intr v_intr: The guest interrupt the vdev uses to request service.
pthread_mutex_t v_mtx: A mutex for the vdev's own use. Use the flags specified by vdev_factory_flags to intitialize this member: VFF_MUTEX (and, optionally, VFF_MUTEX_RECURSIVE).
struct qvm_sched_info v_sched: Scheduler information for the vdev threads.

Description:

The vdev_s structure stores vdev information and provides the definition for the vdev_t data type, which is passed into vdev configuration functions.
