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

Commit Message

Anup Patel Oct. 1, 2014, 10:34 a.m. UTC

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.
