The userspace destination address must have the [[SVC#MemoryState|FlagCanDeviceMap]] bit set. Bit [[SVC#MemoryAttribute|DeviceShared]] will be set after mapping.
The userspace destination address must have the [[SVC#MemoryState|FlagCanDeviceMap]] bit set. Bit [[SVC#MemoryAttribute|DeviceShared]] will be set after mapping.
The Option encodes a [[#MemoryPermission]] in the low 16 bits, and an indicator of IO mapping in the high bits.

Same as [[#MapDeviceAddressSpaceByForce]], but the userspace destination address must have the [[SVC#MemoryState|FlagCanAlignedDeviceMap]] bit set instead.
