This causes all new # architecture features to be made available when running on newer # processors with new architecture features added to the PCR as bits # must be set to disable a given feature. # # For example to disable new features added as part of Version 2.07 of # the ISA the corresponding bit in the PCR needs to be set. # # As new processor features generally require explicit kernel support # they should be disabled until such support is implemented. Therefore # kernels should set all unknown/reserved bits in the PCR such that any # new architecture features which the kernel does not currently know # about get disabled. # # An update is planned to the ISA to clarify that the PCR is an # exception to the Programming Note on reserved bits in Section 1.3.3. # # Signed-off-by: Alistair Popple # Signed-off-by: Jordan Niethe # Tested-by: Joel Stanley
