QEMU must be careful when loading device state off migration streams to
prevent a malicious source from exploiting the emulator. Overdoing these
checks has the side effect of allowing a guest to "pin itself" in cloud
environments by messing with state which is entirely in its control.

Similarly to what f3081539 achieved in usb_device_post_load(), this
commit removes such a check from virtio_load(). Worth noting, the result
of a load without this check is the same as if a guest enables a VQ with
invalid indexes to begin with. That is, the virtual device is set in a
broken state (by the datapath handler) and must be reset.

Prevent future developers working on root complexes, root ports, or
bridges that also wish to implement a BAR for those, from shooting
themselves in the foot. PCI type 1 headers only support 2 base address
registers. It is incorrect and difficult to figure out what is wrong

After Linux kernel commit 61363c1474b1 ("iommu/vt-d: Enable ATS only
if the device uses page aligned address."), ATS will be only enabled
if device advertises a page aligned request.

Unfortunately, vhost-net is the only user and we don't advertise the
aligned request capability in the past since both vhost IOTLB and
address_space_get_iotlb_entry() can support non page aligned request.

Though it's not clear that if the above kernel commit makes
sense. Let's advertise a page aligned ATS here to make vhost device
IOTLB work with Intel IOMMU again.

Note that in the future we may extend pcie_ats_init() to accept
parameters like queue depth and page alignment.

The first loop in vhost_get_log_size() computes the size of the dirty log
bitmap so that it allows to track changes in the entire guest memory, in
terms of GPA.

When not using a vIOMMU, the address of the vring's used structure,
vq->used_phys, is a GPA. It is thus already covered by the first loop.

When using a vIOMMU, vq->used_phys is a GIOVA that will be translated
to an HVA when the vhost backend needs to update the used structure. It
will log the corresponding GPAs into the bitmap but it certainly won't
log the GIOVA.

So in any case, vq->used_phys shouldn't be explicitly used to size the
bitmap. Drop the second loop.

This fixes a crash of the source when migrating a guest using in-kernel
vhost-net and iommu_platform=on on POWER, because DMA regions are put
over 0x800000000000000ULL. The resulting insanely huge log size causes
g_malloc0() to abort.

According to PCIe spec 5.0 Type 1 header space Base Address Registers
are defined by 7.5.1.2.1 Base Address Registers (same as Type 0). The
_CRS region should allow for the same range (up to 64b). Prior to this
change, any host bridge utilizing more than 32b for the BAR would have

vhost IOTLB API uses read()/write() to exchange iotlb messages with
the kernel module.
The QEMU implementation expects a non-blocking fd, indeed commit
c471ad0e ("vhost_net: device IOTLB support") set it for vhost-net.

Without this patch, if we enable iommu for the vhost-vsock device,
QEMU can hang when exchanging IOTLB messages.

As commit 894022e6 ("net: check if the file descriptor is valid
before using it") did for tap, let's use qemu_try_set_nonblock()
when fd is provided by the user.

Reporting "Failed to connect socket" is essentially useless for a user
attempting to diagnose failure. It needs to include the target address
details. Similarly when failing to create a socket we should include the
socket family info, so the user understands what particular feature was
missing in their kernel build (IPv6, VSock in particular).

We want missing symbols fail module load right away instead of having
qemu abort later on in case lazy binding fails.  Can happen -- for
example -- when trying to load a module for a pci device
(virtio-gpu-pci) into a qemu without pci support (qemu-system-avr).

There is no actual code in the CONFIG_VIRGL=n case.  So building is
(a) pointless and (b) makes macos ranlib complain.

Build virtio-gpu vga devices modular.  Must be a separate module because
not all qemu softmmu variants come with VGA support.
