Hi Jeff, Apologies if I am derailing your attempt at getting this support merged, but I am actually proposing to the USWG to make this a config table rather than a EFI variable, for the obvious reason that using a runtime service to decide which runtime services are supported is a bit problematic, and it forces the OS to invent its own way to exchange this information between the OS loader and the OS proper. A configuration table does not have this limitation, so it seems much better suited for this. > .../VarCheckUefiLib/VarCheckUefiLibNullClass.c | 11 +++++++ > MdeModulePkg/Universal/BdsDxe/BdsDxe.inf | 1 + > MdeModulePkg/Universal/BdsDxe/BdsEntry.c | 35 > +++++++++++++++++++++- > MdePkg/Include/Guid/GlobalVariable.h | 7 +++++ > MdePkg/Include/Uefi/UefiSpec.h | 18 +++++++++++ > MdePkg/MdePkg.dec | 18 +++++++++++ > MdePkg/MdePkg.uni | 17 +++++++++++ > 7 files changed, 106 insertions(+), 1 deletion(-) > > -- > 2.7.4 > > > > -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
