摘要:
When executing (S1) firmware of a first hypervisor (1a) stored in a first memory area, an information processing device stores (S2) firmware of a second hypervisor (1b) into a second memory area. The information processing device issues (S3), from the first hypervisor (1a), a stopping instruction that instructs a caller of a hypervisor call to stop issuing a new hypervisor call.. The information processing device rewrites (S4) designating information, that designates a memory area storing firmware of a hypervisor executed by the information processing device, from a first value that designates the first memory area to a second value that designates the second memory area. The information processing device starts execution of the firmware of the second hypervisor in response to the rewriting of the designating information. The information processing device issues (S5), from the second hypervisor to the caller, a canceling instruction that cancels the stopping instruction.
摘要:
A first computing device includes a data transmission processing unit (12) transmitting data to be transferred to another computing device to a first storage area among the plurality of storage areas (25), and an interrupt generating unit (14) generating an interrupt corresponding to transmission of data by the data transmission processing unit (12) with respect to a transmission destination of the data together with identification information specifying the storage area (25), and a second computing device includes an interrupt processing unit (23) specifying from which computing device the interrupt is requested based on the identification information received together with the interrupt when receiving the interrupt, and a data receiving unit (22) reading out data from the first storage area (25) corresponding to the computing device specified by the interrupt processing unit (23) among the plurality of storage areas (25) to efficiently communicate among computing devices in an information processing apparatus including a plurality of computing devices.
