ABSTRACT:
Methods, systems, and computer-readable media track a state of communication between a PS/2 device and a PS/2 device driver within an EFI environment. The method involves receiving from an application, a request for data and in response to receiving the request, reading a state machine table within the PS/2 device driver to determine a last known state of communication associated with the PS/2 device. The last known state of communication is stored within the state machine table. The method also involves, based on the last known state stored, utilizing the state machine table to select and execute a routine to send a command, receive a reply from the PS/2 device to a command, change the state of communication when a condition is met, store changes in the last known state of communication, and/or pass control back to the application thereby reducing delay associated with waiting on slow PS/2 device replies.
