KERNEL REBOOT METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18157967 titled 'KERNEL REBOOT METHOD
Simplified Explanation
The patent application describes an application that allows for a kernel reboot method, which reserves internal memory for storing an entry address of a physical code and a code segment for the physical core. This is exemplified through a kernel hotswap scenario.
- The application provides a method for reserving internal memory for storing an entry address of a physical code and a code segment for the physical core.
- It describes a kernel hotswap scenario where an interrupt is sent to the physical core when a computer system stops executing an old kernel, causing the physical core to enter a busy waiting state.
- When a new kernel is started, the entry address of the physical core is modified, and the physical core in the busy waiting state exits the busy waiting state.
- The physical core then performs an initialization procedure and receives task scheduling of the new kernel.
Potential Applications
- This technology can be applied in computer systems that require kernel reboot methods, such as operating systems and embedded systems.
- It can be used in scenarios where hot swapping of kernels is necessary, allowing for seamless transitions between different kernel versions.
Problems Solved
- The application solves the problem of efficiently rebooting a kernel in a computer system without causing disruptions or delays.
- It addresses the issue of managing the entry address of a physical core during a kernel hotswap scenario, ensuring a smooth transition between kernels.
Benefits
- The method described in the patent application allows for a faster and more efficient rebooting process of a kernel in a computer system.
- It enables seamless transitions between different kernel versions, reducing downtime and improving system reliability.
- The technology provides a reliable and effective way to manage the entry address of a physical core during a kernel hotswap scenario.
Original Abstract Submitted
This application provides a kernel reboot method, to reserve an internal memory for storing an entry address of a physical code and a code segment for the physical core. A kernel hotswap scenario is used as an example. When a computer system stops executing an old kernel, an interrupt is sent to the physical core, so that the physical core enters a busy waiting state. When the computer system starts a new kernel, the entry address of the physical core is modified. When finding that the entry address is modified, the physical core in the busy waiting state exits the busy waiting state, performs an initialization procedure of the physical core, and receives task scheduling of the new kernel.
