Abstract: A system for facilitating efficient hardware-firmware interactions may include (i) a plurality of memory registers, (ii) a hardware module that directly reads from and writes to the plurality of memory registers and is configured to interpret a special marker that distinguishes between register write operations and non-register-write operations, and (iii) a firmware module that directs the hardware module to perform operations at least in part by sending the special marker. Various other methods, systems, and computer-readable media are also disclosed.
