1. A computer-implemented method of initializing a plurality of processor cores of a plurality of processors in a multiprocessor system, the method comprising:
a microcontroller initializing a first processor of the plurality of processors utilizing a common initialization image, wherein the common initialization image is usable to initialize all processor cores within the first processor, and wherein the microcontroller is separate from the plurality of processors; in response to initializing the first processor using the common initialization image, the microcontroller retrieving and loading a system firmware for execution on the first processor; initializing all remaining processors utilizing the common initialization image; detecting, via the executing firmware, a system configuration of the multiprocessor system, wherein detecting the system configuration further comprises probing, within the multiprocessor system, at least one of: one or more inter-processor input/output (I/O) busses between the plurality of processor cores, a system memory, one or more local memories, and one or more other processing components; for each of the processor cores in the multiprocessor system, generating a customized processor initialization image based on settings and parameters identified in the system configuration for that processor core; storing the customized processor initialization images to a memory location within a storage device; triggering all of the processor cores to enter a power save state in which all initialization settings of all of the processor cores are lost; and in response to the microcontroller detecting that all of the processor cores have entered the power save state, the microcontroller re-initializing at least a first processor core of the first processor using a first customized initialization image generated for the first processor core, wherein the microcontroller loads the first customized initialization image from the memory location in the storage device. |
