The default version of EFI_PEI_CPU_IO_PPI support published by PeiServices in
|
||||
PeiCore initialization phase.
|
||||
|
||||
EFI_PEI_CPU_IO_PPI is installed by some platform or chipset-specific PEIM that
|
||||
abstracts the processor-visible I/O operations. When PeiCore is started, the
|
||||
default version of EFI_PEI_CPU_IO_PPI will be assigned to PeiServices table.
