Problems solved by technology

Since the existing Hot-Plug technology needs to rely on the support of hardware platforms other than the operating system (for example, hot-swappable controllers, various name spaces under various platforms are not the same), it cannot be completed independently by a single hardware device

Abstract

The embodiment of the invention discloses a memory change processing method and operating systems. The memory change processing method is used for performing memory change processing on a plurality of multi-core operating systems. The method provided by the embodiment of the invention comprises the following steps that a first operating system obtains a memory resource change indication message, wherein the indication message is used for indicating that the memory resource of a second operating system changes; the first operating system builds an ACPI (Advanced Configuration and Power Interface) data table according to the indication message; and the first operating system sends an IPI (Inter-Processor Interrupt) instruction to the second operating system so that the second operating system generates an SCI (System Control Interrupt) lower half part event through an IPI event in a simulated way according to the IPI instruction, and the second operating system runs the SCI lower half part event through reading the ACPI data table.

Description

technical field [0001] The invention relates to the field of computers, in particular to a memory modification processing method and an operating system. Background technique [0002] The multi-core multi-operating system refers to starting an operating system on one or more cores respectively in a multi-core system, and these operating systems together form a multi-core multi-operating system. For example, the Rainforest system. [0003] In a multi-core multi-operating system (OS, Operating System), there are two operating systems; a management operating system (such as HeavyOS in the Rainforest system) used for resource management respectively, and an operating system allocated based on the management operating system A lightweight operating system created by system resources (such as LightOS in the Rainforest system); wherein, the management operating system is a general-purpose operating system with functions such as resource allocation, recycling, virtualization, and c...
