The implementation of this new behavior aligns with the guidelines outlined in the Intel SDM.
Following a power-up or RESET of an MP system, system hardware dynamically selects one of the processors on the system bus as the BSP. The remaining processors are designated as APs. The APs complete a minimal self-configuration, then wait for SIPI from the BSP processor Yuanhao Xie (1): UefiCpuPkg: Add SendStartupIpiAllExcludingSelf YuanhaoXie (3): UefiCpuPkg: Add PcdFirstTimeWakeUpAPsBySipi OvmfPkg: Disable PcdFirstTimeWakeUpAPsBySipi. UefiCpuPkg:Wake up APs after power-up or RESET through SIPI.
