Automatic update of persistent boot parameter storage

摘要

A computer system includes a memory, the memory comprising a hardware boot parameter storage area; an operating system running on the computer system; and reboot logic configured to: store updated boot parameters for the operating system in the hardware boot parameter storage area in the memory; perform a reboot of the operating system with the updated boot parameters; determine whether the reboot of the operating system is successful, and, in the event the reboot of the operating system is successful, automatically propagate the updated boot parameters to a persistent boot parameter storage area.

1. A computer system comprising:
a plurality of partitions; a main memory, the main memory comprising a hardware boot parameter storage area; an operating system running on a first partition of the plurality of partitions the computer system; and reboot logic configured to: boot the operating system of the first partition of the plurality of partitions of the computer system based on first boot parameters corresponding to the first partition that are stored in a persistent boot parameter storage area, wherein the persistent boot parameters storage area stores respective boot parameters for each of the plurality of partitions; receive updated boot parameters for the operating system of the first partition from a user; store the updated boot parameters for the operating system of the first partition of the computer system in the hardware boot parameter storage area in the main memory, the hardware boot parameter storage area being distinct from the persistent boot parameter storage area, and wherein the hardware boot parameter storage area and the persistent boot parameters storage area are not located in any of the plurality of partitions; perform a reboot of the operating system in the first partition based on the updated boot parameters that are stored in the hardware boot parameter storage area; determine whether the reboot of the operating system in the first partition based on the updated boot parameters was successful; and, based on the reboot of the operating system in the first partition based on the updated boot parameters being successful, automatically propagate the updated boot parameters from the hardware boot parameter storage area to the persistent boot parameter storage area.
