Abstract
In accordance with various aspects of the disclosure, a method and apparatus are disclosed that includes aspects of monitoring a first processor of a computer by a monitoring module for a first processor instability; determining if the first processor is stable based on the monitored first processor instability; routing operational priority to a second processor of the computer through a multiplexer module if the first processor is determined not to be stable, wherein a first interface of the first processor and a second interface of the second processor are in communication with the multiplexer module and wherein the first processor and the second processor are in communication by a processor interconnect; and operating the computer using the second processor.
Claims14
A method comprising:
- monitoring, by a monitoring module, one or more parameters related to a computer, the one or more parameters comprising a power mode;
- monitoring, by the monitoring module, for instability of a second processor, wherein the instability comprises a pre-boot instability and a post-boot instability in the computer, and
- designating, by a controller, a first processor as a boot processor based at least on the monitored power mode and the instability of the second processor, wherein the first processor is initially configured as a non-boot processor,
- wherein the first processor is connected to a second processor through an interconnect.
An apparatus comprising:
- a first processor configured as a non-boot processor;
- a second processor configured to be in communication with the first processor through an interconnect;
- a monitor configured to monitor one or more parameters related to a computer, the one or more parameters comprising a power mode, and monitor for instability of the second processor, wherein the instability comprises a pre-boot instability and a post-boot instability in the computer;
- and
- a controller configured to designate the first processor as a boot processor based at least on the monitored power mode and the instability of the second processor.
