Abstract:
An information processing apparatus includes a device that performs data processing; and processors, each processor including a device driver corresponding to the device. A device driver set in correspondence with at least one processor has a resource-state holding unit that manages a resource flag indicating which processor is using or is scheduled to use resources used at the time of data processing using the device. At least one processor sets the resource flag to a flag value indicating that at least one processor is scheduled to use the resources in accordance with a schedule of at least one processor to use the device. At least one processor terminates or interrupts use of the device when at least one processor refers to the resource flag and recognizes that another processor is scheduled to use the resources during a period in which at least one processor is using the device.
