[edk2] [PATCH] MdeModulePkg/S3SaveState: Extract arguments in correct order
Posted by Ruiyu Ni 6 years, 6 months ago 
EFI_BOOT_SCRIPT_WRITE() interface is a var-arg interface.

Spec defines the order of parameters for
EFI_BOOT_SCRIPT_PCI_CONFIG2_WRITE_OPCODE as below:

  typedef
  EFI_STATUS
  (EFIAPI *EFI_BOOT_SCRIPT_WRITE) (
    IN CONST EFI_S3_SAVE_STATE_PROTOCOL *This,
    IN UINT16 OpCode,
    IN EFI_BOOT_SCRIPT_WIDTH Width,
    IN UINT16 Segment,
    IN UINT64 Address,
    IN UINTN Count,
    IN VOID *Buffer
  );

But implementation assumes Segment is in the very end, after Buffer.
Similar spec/implementation gaps are also found for
EFI_BOOT_SCRIPT_PCI_CONFIG2_READ_WRITE_OPCODE.

The patch fixes the implementation to extract the arguments in
correct order.
