Abstract: A polling device driver is partitioned into a plurality of driver threads for controlling a device of a computer system. The device has a first device state of an unscouted state and a scouted state, and a second device state of an inactive state and an active state. A driver thread of the plurality of driver threads determines that the first device state of the device state is in the unscouted state, and changes the first state of the device to the scouted state. The driver thread further determines that the second device state of the device is in the inactive state and changes the second device state of the device to the active state. The driver thread executes an operation on the device during a pre-determined time slot configured for the driver thread.

Abstract: A method of implementing a multi-threaded device driver for a computer system is disclosed. A polling device driver is partitioned into a plurality of driver threads for controlling a device of a computer system. The device has a first device state of an unscouted state and a scouted state, and a second device state of an inactive state and an active state. A driver thread of the plurality of driver threads determines that the first device state of the device state is in the unscouted state, and changes the first state of the device to the scouted state. The driver thread further determines that the second device state of the device is in the inactive state and changes the second device state of the device to the active state. The driver thread executes an operation on the device during a pre-determined time slot configured for the driver thread.
