REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1973 For semaphore type register, it required all processors to do the task at the same time. Current logic begins BSP's task after all APs have finished their tasks. This will caused set semaphore task hang if semaphore has package level type. This patch use new EDKII_PEI_MP_SERVICES2_PPI to start all processors at the same time to fix the potential hang issue.
