[PATCH v5 2/4] kvmtool: ARM64: Add target type potenza for aarch64

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

 



The VCPU target type KVM_ARM_TARGET_XGENE_POTENZA is available
in latest Linux-3.16-rcX or higher hence register aarch64 target
type for it.

This patch enables us to run KVMTOOL on X-Gene Potenza host.
