Multiple initialization techniques for
system and component in a point-to-point architecture are discussed. Consequently, the techniques allow for flexible
system / socket layer parameters to be tailored to the needs of the platform, such as, desktop, mobile, small
server, large
server, etc., as well as the component types such as IA32 / IPF processors, memory controllers, IO Hubs, etc. Furthermore, the techniques facilitate powering up with the correct set of POC values, hence, it avoids multiple warm resets and improves boot time. In one embodiment, registers to hold new values, such as, Configuration Values Driven during Reset (CVDR), and Configuration Values Captured during Reset (CVCR) may be eliminated. For example, the POC values could be from the following: Platform Input
Clock to Core
Clock Ratio, Enable / disable LT, Configurable Restart,
Burn In Initialization Mode, Disable Hyper Threading,
System BSP Socket Indication, and Platform Topology Index.
