This change is made given a request from Ard. The CC capability is not applied to other system memory ranges that probably should also have that capability, given that it's encrypted and accepted. I haven't considered carefully where EFI_MEMORY_CPU_CRYPTO should be added to conventional memory, given the acceptance happens before DXE initializes. Perhaps CoreConvertResourceDescriptorHobAttributesToCapabilities? This is more of a question to Ard and Thomas. -- -Dionna Glaze, PhD (she/her) -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
