Problems solved by technology

[0008] However, on a kernel including a complex memory management mechanism such as Linux (registered trademark), the DMA controller cannot write data to an arbitrary address in a memory area managed by the kernel
Thus, it is difficult to read the hibernate image in parallel with the initialization of the kernel by the conventional hibernate boot method

Abstract

The invention discloses an information processing apparatus and an information processing method. The hibernation start-up by the kernel function takes a long time due to a processing time required for a normal boot sequence. When starting an operating system, the information processing apparatus according to the present invention determines whether to perform the hibernation start-up processing before initialization of a memory management mechanism. When the hibernation start-up processing is performed, a size of the memory management mechanism is reduced to a minimum size necessary for initializing the kernel and a hibernation image is read in parallel with initialization of hardware. The limited memory management area can be restored to a state free from a limitation by reading the hibernation image.

Description

technical field [0001] The present invention relates to a technique for high-speed activation of an information processing device including a hibernation mechanism. Background technique [0002] In recent years, hibernation utilized in an information processing device that can reduce power consumption when the information processing device is in a standby state has attracted attention. Hibernation is the mechanism used to interrupt the system. During system operation, at the time of hibernation, information blocks included in memory or central processing unit (CPU) registers (hereinafter referred to as “hibernation image”) are saved to a non-volatile storage device such as a hard disk. If the power is then turned off, when the system is started next time, the same state as before can be restored by reading the hibernation image (hereinafter, referred to as "hibernation start"). Hibernation can be used for the purpose of reducing the boot time of the system. [0003] Hiber...
