The current VFIO-on-POWER implementation supports only user mode

It does not make much sense to have KVM in book3s-64bit and

Subject: Re: [PATCH 2/5] booke: exit to
Hi,
I am trying to disable the mergeable rx buffers for a Linux guest but I am
currently unable to do so.
I tried looking in the code of libvirt in order to find the -global
virtio-net-pci.mrg_rxbuf=off but the only globals configured are:
PIIX4_PM.disable_s*, isa-fdc.drive, isa-fdc.bootindex,
Exit to guest user space if kvm does not implement the hcall.

This patchset implements the hcall exit interface to userspace.
Also we added reset and shutdown hcall
Bharat Bhushan (5):
powerpc: define ePAPR hcall exit interface
booke: exit to guest userspace for unimplemented hcalls in kvm
booke:
KVM_HC_VM_RESET: Requests that the virtual machine be reset.
KVM_HC_VM_SHUTDOWN: Requests that the virtual machine be powered-off/halted.
These hcalls are handled by guest userspace.

Detect the availability of the reset hcalls by looking at kvm,has-reset
property on the /hypervisor node in the device tree passed to the VM and
patches the reset mechanism to use reset hcall.
This patch uses the reser hcall when kvm,has-reset is there in

The subject line is misleading. This is a kvm patch. Same applies for most
other patches.
