Patent number: 8606934
Abstract: 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.
