Hi,
As I recall hyp_loaded option was introduced in context of Hafnium used as a NS EL2 hypervisor. Is this a configuration you use?
This option is only related to normal world VMs. I don't believe it was designed for SPs or the SPMC image itself. One reason is that SEL2/SPMC starts before the NS EL2 hypervisor in the boot flow.
For the record, the change that introduced this option: https://review.trustedfirmware.org/c/hafnium/hafnium/+/10540
Regards, Olivier.

Hi, expert I want to confirm a problem about using hafnium to load spmc payload. That is, Dose hafnium supports hyp_loaded for spmc payload or ffa_partion (such as optee_os) in the boot phase? If the community confirms that it does not support it, I wonder, what might be the problem with doing so? I see the following code in hanfnium： if (manifest->vm[i].is_ffa_partition && !manifest->vm[i].is_hyp_loaded) { TRY(parse_ffa_partition_package(stage1_locked, &vm_node, &manifest->vm[i], vm_id, ppool)); } else { TRY(parse_vm(&vm_node, &manifest->vm[i], vm_id)); } It seems that hafnium has no handling for both is_ffa_partition and is_hyp_loaded. regards, yuye -- Hafnium mailing list -- hafnium@lists.trustedfirmware.org To unsubscribe send an email to hafnium-leave@lists.trustedfirmware.org
