kvm: Add VFIO device

2013-10-30T18:02:03+00:00

So far we've succeeded at making KVM and VFIO mostly unaware of each other, but areas are cropping up where a connection beyond eventfds and irqfds needs to be made. This patch introduces a KVM-VFIO device that is meant to be a gateway for such interaction. The user creates the device and can add and remove VFIO groups to it via file descriptors. When a group is added, KVM verifies the group is valid and gets a reference to it via the VFIO external user interface. Signed-off-by: Alex Williamson Signed-off-by: Paolo Bonzini

kvm: Add KVM_GET_EMULATED_CPUID

2013-10-30T17:54:39+00:00

Add a kvm ioctl which states which system functionality kvm emulates. The format used is that of CPUID and we return the corresponding CPUID bits set for which we do emulate functionality. Make sure ->padding is being passed on clean from userspace so that we can use it for something in the future, after the ioctl gets cast in stone. s/kvm_dev_ioctl_get_supported_cpuid/kvm_dev_ioctl_get_cpuid/ while at it.

kvm: powerpc: book3s: Allow the HV and PR selection per virtual machine

2013-10-17T16:42:36+00:00

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

ARM/ARM64: KVM: Implement KVM_ARM_PREFERRED_TARGET ioctl

2013-10-02T18:29:48+00:00

For implementing CPU=host, we need a mechanism for querying preferred VCPU target type on underlying Host. This patch implements KVM_ARM_PREFERRED_TARGET vm ioctl which returns struct kvm_vcpu_init instance containing information about preferred VCPU target type and target specific features available for it.

arm64: KVM: enable initialization of a 32bit vcpu

2013-06-12T15:42:18+00:00

Wire the init of a 32bit vcpu by allowing 32bit modes in pstate, and providing sensible defaults out of reset state. This feature is of course conditioned by the presence of 32bit capability on the physical CPU, and is checked by the KVM_CAP_ARM_EL1_32BIT capability.
