Abstract

The invention relates to an information processing apparatus, a control method, a non-transitory storage medium, and a vehicle. An information processing device equipped with a virtual machine monitor capable of implementing a plurality of virtual machines is provided with a CPU including a plurality of CPU cores, the CPU being configured so as to execute a first virtual machine when the virtual machine to be executed among the plurality of virtual machines is a first virtual machine having a request level related to functional security equal to or greater than a predetermined reference, and a second virtual machine having a request level related to functional security equal to or greater than a predetermined reference. At least two or more CPU cores among the plurality of CPU cores are caused to execute the processing of the same first virtual machine.

Description

technical field [0001] The present disclosure relates to an information processing apparatus, a control method, a non-transitory storage medium, and a vehicle. Background technique [0002] A control device using dual-core lockstep (LSDC) technology is disclosed in International Publication No. 2018 / 198184. In the control device described in International Publication No. 2018 / 198184, when an application is operated in a first CPU (Central Processing Unit) having an LSDC function and a second CPU having no LSDC function, a failure occurs in the second CPU Next, the lockstep mode of the first CPU is released, and the application operating on the second CPU is caused to fall back to operate on one of the CPU cores constituting the first CPU. Thereby, the control device described in International Publication No. 2018 / 198184 suppresses the influence when the second CPU fails. [0003] However, the control performed by the control device described in the above-mentioned Internat...
