From cbbc58d4fdfab1a39a6ac1b41fcb17885952157a Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Mon, 7 Oct 2013 22:18:01 +0530 Subject: kvm: powerpc: book3s: Allow the HV and PR selection per virtual machine This moves the kvmppc_ops callbacks to be a per VM entity. This enables us to select HV and PR mode when creating a VM. We also allow both kvm-hv and kvm-pr kernel module to be loaded. To achieve this we move /dev/kvm ownership to kvm.ko module. Depending on which KVM mode we select during VM creation we take a reference count on respective module Signed-off-by: Aneesh Kumar K.V [agraf: fix coding style] Signed-off-by: Alexander Graf --- include/uapi/linux/kvm.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/uapi/linux') diff --git a/include/uapi/linux/kvm.h b/include/uapi/linux/kvm.h index e32e776f20c0..5b5341f78368 100644 --- a/include/uapi/linux/kvm.h +++ b/include/uapi/linux/kvm.h @@ -518,6 +518,10 @@ struct kvm_ppc_smmu_info { /* machine type bits, to be used as argument to KVM_CREATE_VM */ #define KVM_VM_S390_UCONTROL 1 +/* on ppc, 0 indicate default, 1 should force HV and 2 PR */ +#define KVM_VM_PPC_HV 1 +#define KVM_VM_PPC_PR 2 + #define KVM_S390_SIE_PAGE_OFFSET 1 /* -- cgit v1.2.1
