Interface guest_vm_arch.h

The guest arm vm interface is central to using libsel4vm on an ARM platform, providing definitions of the arm guest vm datastructures and primitives to configure the VM instance.

Brief content:

Functions:

vm_register_unhandled_vcpu_fault_callback(vcpu, vcpu_fault_callback, cookie)

Structs:

vm_vcpu_arch

Functions

The interface guest_vm_arch.h defines the following functions.

Function vm_register_unhandled_vcpu_fault_callback(vcpu, vcpu_fault_callback, cookie)

Register a callback for processing unhandled vcpu faults

Parameters:

  • vcpu {vm_vcpu_t *}: A handle to the VCPU
  • A {unhandled_vcpu_fault_callback_fn}: user supplied callback to process unhandled vcpu faults
  • A {void *}: cookie to supply to the vcpu fault handler

Returns:

  • 0 on success, -1 on error

Structs

The interface guest_vm_arch.h defines the following structs.

Struct vm_vcpu_arch

Structure representing ARM specific vcpu properties

Elements:

  • fault {fault_t *}: Current VCPU fault
  • unhandled_vcpu_callback {unhandled_vcpu_fault_callback_fn}: A callback for processing unhandled vcpu faults
  • unhandled_vcpu_callback_cookie {void *}: A cookie to supply to the vcpu fault handler
