> Subject: Re: [PATCH 20/37] xen: introduce CONFIG_EFI to stub API for no
wo secure state, like GIC. But fortunately, most
vendors will not link a two secure state GIC to Armv8-R64 processors.
Current GIC driver can work well with single secure state GIC for Armv8-R64.
2. Xen should use secure hypervisor timer in Secure EL2. We will introduce
a CONFIG_ARM_SECURE_STATE to make Xen to use secure registers for timer.
### **2.7. Changes of virtual device**
Currently, we only support pass-through devices in guest. Because event
channel, xen-bus, xen-storage and other advanced Xen features haven't been
enabled in Armv8-R64.
