Sorry, I'm not familiar with KVM, but I got a question here, will
KVM works without valid vcpu_base in GICv3 mode?
Yes, KVM works without vcpu_base in GICv3 mode. The vcpu_base will be used
for emulatingvGICv2 feature. The vGICv3 emulation isdone through the
system registers.
vcpu_base is only required for supporting GICv2 on GICv3.
Yes, you are right,
Thanks for the clarify.
