Non-inductive upgrade method for interrupt processing program, and computer system

A method for seamless upgrade of an interrupt handling program, comprising:

• responding, by a baseboard management controller (BMC), to an upgrade operation for an interrupt handling program to be upgraded, and acquiring the interrupt handling program to be upgraded and upgrade parameters of the interrupt handling program to be upgraded, wherein the upgrade parameters comprise an interrupt number and a code length, and an interrupt number of the interrupt handling program to be upgraded is consistent with an interrupt number of a historical interrupt handling program corresponding to the interrupt handling program to be upgraded;
• storing, by the BMC, the interrupt handling program to be upgraded in basic input output system (BIOS) Flash according to the upgrade parameters, overwriting the historical interrupt handling program corresponding to the interrupt handling program to be upgraded in the BIOS Flash, and sending an upgrade interrupt signal to an interrupt handler;
• responding, by the interrupt handler, to the upgrade interrupt signal, and starting an interrupt upgrade program;
• and
• acquiring, by the interrupt upgrade program, the upgrade parameters of the interrupt handling program to be upgraded, determining a storage location of the interrupt handling program to be upgraded in the BIOS Flash according to the interrupt number, and reading the interrupt handling program to be upgraded according to the code length of the interrupt handling program to be upgraded;
• and
• determining, by the interrupt upgrade program, a location in the physical memory address where the historical interrupt handling program corresponding to the interrupt handling program to be upgraded is stored according to the interrupt number, and overwriting the historical interrupt handling program corresponding to the interrupt handling program to be upgraded in the physical memory address with the interrupt handling program to be upgraded, to be regarded as a new interrupt handling program.
