When i was traversing the following code in file UefiCpuPkg/CpuMpPei/CpuPaging.c In function SetupStackGuardPage we ASSERT if find any StackBase address as 0x00. Why StackBase address for BSP cannot be zero, any specific reason? In file edk2/MdeModulePkg/Core/Pei/Dispatcher/Dispatcher.c at line number 788 --> TopOfNewStack = Private->PhysicalMemoryBegin + NewStackSize; Can not Private->PhysicalMemoryBegin be 0x00, if not why is should not be 0x00? -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
