[PATCH v4 01/15] KVM: arm64: placeholder to check if VM is protected

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a function to check whether a VM is protected (under pKVM).
Since the creation of protected VMs isn't enabled yet, this is a
placeholder that always returns false. The intention is for this
to become a check for protected VMs in the future (see Will's RFC).

No functional change intended.
