Abstract

Platform controller, computer-readable storage media, and methods associated with initialization of a computing device. In embodiments, a platform controller may comprise a boot controller and one or more non-volatile memory modules, coupled with the boot controller. In embodiments, the one or more non-volatile memory modules may have first instructions and second instructions stored thereon. The first instructions may, when executed by a processor of a computing device hosting the platform controller, cause initialization of the computing device. The second instructions, when executed by the boot controller, may cause the boot controller to monitor at least a portion of the execution of the first instructions by the computing device and may generate a trace of the monitored portion of the execution of the first instructions. In embodiments, the trace may be stored in the one or more non-volatile memory modules. Other embodiments may be described and/or claimed.
