The main reason why such a library is desirable is to 9 be able to send arbitrary \ac{ata} commands via \ac{ahci} without having to 10 bother with the \ac{ahci} specification details. 14 \libahci abstracts the low-level \ac{ahci} operations such as the writing to 15 memory mapped control registers of the \ac{hba}.
