Subject: [PATCH 2/2] arm64: KVM: Add VCPU support for Qualcomm Technologies Kryo ARMv8 CPU
Date: Fri, 12 Jun 2015 16:57:43 -0500	[thread overview]
Message-ID: <1434146263-30972-2-git-send-email-timur@codeaurora.org> (raw)
In-Reply-To: <1434146263-30972-1-git-send-email-timur@codeaurora.org>

From: Shanker Donthineni <shankerd@codeaurora.org>

This patch enables assignment of 32/64bit guest VCPU to
Qualcomm Technologies ARMv8 CPU. Added KVM_ARM_TARGET_QCOM_KRYO
to the KVM target list and modified vm_target_cpu() to return
KVM_ARM_TARGET_QCOM_KRYO when CPU running in AArch64 mode.
