There isn't that much of a difference between the normal and amd sev build. It has additional drivers and the grub boot loader added, smm support turned off, network stack removed. The differences between config-a and config-b are much larger according to the design document. config-b has a completely different initialization code path, skipping the PEI phase. I see that as a major problem when it comes to long-term maintenance, and so far nobody could explain the reason for this. I'll go read the links to old discussions sent by Min, maybe I find something there. Having a config-b with network stack disabled, driver for RTMR trusted boot added, maybe some other little tweaks but otherwise a boot workflow identical to config-a is reasonable in my eyes. Merging it with AmdSev should also be relatively easy then. take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
