Hi All, While enabling trusty os with xen, I took same approach as OP-TEE, with OP-TEE running in secure world. But I am also thinking this might introduce potential issue is that secure world OS communicate with DomU. If there are some misbehavior in secure world OS, it might let XEN hypervisor not work proper.
In my setup, trusty os sometimes panic in secure world, xen will not able to control the panic core anymore. So I am thinking whether we need to emulating secure world in a XEN VM which is the VM running DomU. Just like what ACRN did to run trusty os. Any comments? Thanks, Peng.
