[Linaro-open-discussions] [Question - ARM CCA] Regarding vCPU Hotplug Support in ARM Realm world

Hi James, I recently got a chance to look into the ARM CCA specifications. And if I understood correctly then in Realm world PSCI is managed by RMM but the Realm vCPUs are taken care by the host.

As per our recent changes we handle the SMC/HVC hyper call exits in user-space. If the VMs are to run in Realm world and vCPU Hotplug needs to be supported then do we need to consider any change there?

Thanks Salil
