Acked-by: Gerd Hoffmann <kra...@redhat.com> As you mention secure boot: As far I know current state of affairs is that nothing protects efi variable flash on ArmVirt, so secure boot isn't actually secure because the OS can easily manipulate 'db' etc. State of affairs on physical hardware (at least on Qualcomm SoCs) seems to be that there is some service running in the Trusted Zone secure world which manages (and controls access to) EFI variables. See https://lore.kernel.org/lkml/eaa455ed-2dd2-a33f-6420-a75484ecc...@gmail.com/t/ Do you happen to know whenever any of this is available as open source, be it the secure world code or the EFI drivers talking to it? Is there some kind of standard for this or does every vendor brew its own? thanks & take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
