Abstract

Embodiments are directed to improving boot process for early display initialization and visualization. An embodiment of a system includes a plurality of processor cores; a cache coupled to the plurality of processor cores; and a controller circuit to: initialize a portion of the cache as static memory for hardware initialization code usage before beginning execution of the hardware initialization code after a power on of the hardware processor; and cause initialization of a display device to be performed using the portion of the cache, the initialization of the display device performed independently of initialization of dynamic memory of the hardware processor.
