'''Description:''' Maps an attached device address space to an userspace address. | |||
dev_map_addr is the userspace destination address, while dev_as_addr is the source address between dev_as_start_addr and dev_as_end_addr (passed to [[#svcCreateDeviceAddressSpace]]). | |||
The userspace destination address must have the [[SVC#MemoryState|MapDeviceAllowed]] bit set. Bit [[SVC#MemoryAttribute|IsDeviceMapped]] will be set after mapping. | |||
