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.
