IntelFsp2WrapperPkg: Rebase FSP-S and FSP-I if Image Base not match

2025-10-30T08:13:29+00:00

FSP Spec says: "The FSP is not Position Independent Code (PIC) and each FSP component has to be rebased if it is placed at a location which is different from the preferred base address specified during the FSP build." Normally, the FSP location in flash is the same preferred base address specified during the FSP build. To avoid FSP-S and FSP-I running directly from flash, platform may copy the FSP binaries into physical memory. This causes FSP location to be different from the preferred base address. To support this, this commit checks the Image Base from FSP header and the FSP base address PCD. If these two are different, This commit assumes the FSP is copied into physical memory and FSP location is changed. In such scenario, the commit will rebase the FSP to the address provided by the PCD. Signed-off-by: Zhiguang Liu

IntelFsp2WrapperPkg: Bootloader need to recover fs and gs

2025-03-05T18:21:49+00:00

When enter FSP, bootloader need to save fs and gs, when back to bootloader, bootloader need to restore fs and gs, so it could avoid bootloader access wrong data segment when usging fs and gs.

MdePkg: MdeLibs.dsc.inc: Apply StackCheckLibNull to All Module Types

2024-11-13T21:01:46+00:00

Now that the ResetVectors are USER_DEFINED modules, they will not be linked against StackCheckLibNull, which were the only modules causing issues. So, we can now remove the kludge we had before and the requirement for every DSC to include StackCheckLibNull for SEC modules and just apply StackCheckLibNull globally. This also changes every DSC to drop the SEC definition of StackCheckLibNull. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Oliver Smith-Denny
