24d1eb33eb Add vhost_ops to vhost_dev struct and replace all relevant ioctls
Decouple vhost from the Linux kernel by introducing vhost_ops. The
intention is to provide different backends - a 'kernel' backend based on
the ioctl interface, and an 'user' backend based on a UNIX domain socket
and shared memory interface.

81647a655f vhost_net_init will use VhostNetOptions to get all its arguments
vhost_dev_init will replace devfd and devpath with a single opaque argument.
This is initialised with a file descriptor. When TAP is used (through
vhost_net), open /dev/vhost-net and pass the fd as an opaque parameter in
VhostNetOptions. The same applies to vhost-scsi - open /dev/vhost-scsi and
pass the fd.

212d69f25e vhost_net should call the poll callback only when it is set
The poll callback needs to be called when bringing up or down
the vhost_net instance. As it is not mandatory for an NetClient
to implement it, invoke it only when it is set.

f57fcf7063 virtio-net: announce self by guest
It's hard to track all mac addresses and their configurations (e.g
vlan or ipv6) in qemu. Without this information, it's impossible to
build proper garp packet after migration. The only possible solution
to this is let guest (who knows all configurations) to do this.

So, this patch introduces a new readonly config status bit of virtio-net,
VIRTIO_NET_S_ANNOUNCE which is used to notify guest to announce
presence of its link through config update interrupt.When guest has
done the announcement, it should ack the notification through
VIRTIO_NET_CTRL_ANNOUNCE_ACK cmd. This feature is negotiated by a new
feature bit VIRTIO_NET_F_ANNOUNCE (which has already been supported by
Linux guest).

During load, a counter of announcing rounds is set so that after the vm is
running it can trigger rounds of config interrupts to notify the guest to build
and send the correct garps.

Note:
GCompareFunc(a, b) used by g_slist_insert_sorted() returns 'gint',
however it might be too small to fit difference between
2 addresses. So use 128bit to calculate the difference and normalize
result to -1/0/1 return values.

10b7e74bf2 pc: implement pc-dimm device abstraction
Each hotplug-able memory slot is a PCDIMMDevice.
A hot-add operation for a memory device:
- creates a new PCDIMMDevice and makes hotplug controller to map it into
  guest address space

Hotplug operations are done through normal device_add commands.
For migration case, all hotplugged memory devices on source should be
specified on target's command line using '-device' option with
properties set to the same values as on source.

To simplify review, patch introduces only PCDIMMDevice QOM skeleton that
will be extended by following patches to implement actual memory hotplug
and related functions.

9dbae97723 spapr_pci: Advertise MSI quota
Hotplug of multiple disks fails due to MSI vector quota check.
Number of MSI vectors default to 8 allowing only 4 devices.
This happens on RHEL6.5 guest. RHEL7 and SLES11 guests fallback
to INTX.

One way to workaround the issue is to increase total MSIs,
so that MSI quota check allows us to hotplug multiple disks.

This sets the quota to the maximum number of interupts XICS has
which is 1024 now (XICS_IRQS). This moves XICS_IRQS from spapr.c
to xics.h for wider visibility.

23825581d7 spapr: Add kvm-type property

d5ac4f5433 spapr_hcall: Add address-translation-mode-on-interrupt resource in H_SET_MODE
This adds handling of the RESOURCE_ADDR_TRANS_MODE resource from
the H_SET_MODE, for POWER8 (PowerISA 2.07) only.

This defines AIL flags for LPCR special register.

This changes @excp_prefix according to the mode, takes effect in TCG.

This turns support of a new capability PPC2_ISA207S flag for TCG.

f7d6914654 PPC: spapr: Expose /hypervisor node in device tree
PR KVM supports an ePAPR compliant hypercall interface in parallel to the
normal sPAPR one. Expose the ePAPR /hypervisor node and properties to the
guest so it can use it.

This enables magic page sharing on PR KVM with -M pseries.

However we had a few nasty bugs in the magic page implementation on vcpus
newer than 970 (p7, p8) that KVM now has workarounds for. It indicates that
it does have these workarounds through the PPC_FIXUP_HCALL capability.

To not expose broken guest kernels to issues on host kernels that don't
have the fixups in place, we don't expose working hypercall instructions
when the fixups are not available so that the guest can never active the
magic page.

f2e2bc9ca0 hw/pci-host/ppce500: Fix typo in vmstate definition
Fix a typo in the ppce500_pci vmstate definition which meant that
we were migrating the struct pci_inbound using the vmstate for
pci_outbound. Fortunately the two structures have exactly the same
format at the moment (four uint32_ts) so this was harmless, and
we can correcting the typo without a migration compatibility
break because the vmstate name doesn't go out on the wire.

650f33adbd spapr_iommu: Introduce page_shift in sPAPRTCETable
At the moment only 4K pages are supported by sPAPRTCETable. Since sPAPR
spec allows other page sizes and we are going to implement them, we need
page size to be configrable.

This adds @page_shift into sPAPRTCETable and replaces SPAPR_TCE_PAGE_SHIFT
with it where it is possible.

523e7b8ab8 spapr_iommu: Get rid of window_size in sPAPRTCETable
This removes window_size as it is basically a copy of nb_table
shifted by SPAPR_TCE_PAGE_SHIFT. As new dynamic DMA windows are
going to support windows as big as the entire RAM and this number
will be bigger that 32 capacity, we will have to do something
about @window_size anyway and removal seems to be the right way to go.

This removes dma_window_start/dma_window_size from sPAPRPHBState as
they are no longer used.
