| 20120047285 | INTERRUPT-BASED COMMAND PROCESSING - In general, this disclosure describes techniques that allow communication between devices/modules of a computer system regarding inter-device/module command execution. In accordance with the techniques described herein, an operating device of a computing system may receive from a client one or more command indications of commands to be executed on the operating device. The operating device may further receive at least one command completion indicator that indicates a command for which one or more clients are awaiting completion of execution. The operating device may generate an interrupt that indicates completion of execution of the command for which the at least one command completion indicator was received. The interrupt may be a generic interrupt or a client-specific interrupt. In this manner, inefficiencies caused by client monitoring of operating device command execution may be reduced. | 02-23-2012 |
