hv_vm_map(_:_:_:_:)
Maps a region in the virtual address space of the current process into the guest physical address space of the VM.
Declaration
func hv_vm_map(_ addr: UnsafeMutableRawPointer, _ ipa: hv_ipa_t, _ size: Int, _ flags: hv_memory_flags_t) -> hv_return_tParameters
- addr:
The address in the current process. It must be page-aligned.
Apple silicon only.
- ipa:
The address in the intermediate physical address space. It must be page-aligned.
Apple silicon only.
- size:
The size of the mapped region in bytes. It must be a multiple of the page size.
- flags:
The permissions for the mapped region. For a list of valid options, see Hv_memory_flags_t.
Return Value
HV_SUCCESS if the operation was successful, otherwise an error code specified in hv_return_t.
Discussion
The host memory must encompass a single VM region, typically allocated with mmap or mach_vm_allocate instead of malloc.
Intel-based Mac computers have different parameters:
uvaThe address in the current process. It must be page-aligned.
gpaThe address in the guest physical address space. It must be page-aligned.
