There are 3 virtqueues (ctrl, event and cmd) for virtio scsi device,
but seabios will only set the physical address for the 3rd one (cmd).
Then in vhost_virtqueue_start(), virtio_queue_get_desc_addr()
will be 0 for ctrl and event vq.
In this case, ctrl and event vq are not initialized.
vhost_verify_ring_mappings may use uninitialized vhost_virtqueue
such that vhost_verify_ring_part_mapping returns ENOMEM.
When encountered this problem, we got the following logs:

In commit 9fa99d2519 ("hw/pci-host: Fix x86 Host Bridges 64bit PCI
hole", 2017-11-16), we meant to expose such a 64-bit PCI MMIO aperture in
the ACPI DSDT that would be at least as large as the new "pci-hole64-size"
property (2GB on i440fx, 32GB on q35). The goal was to offer "enough"
64-bit MMIO aperture to the guest OS for hotplug purposes.
In that commit, we added or modified five functions:
- pc_pci_hole64_start(): shared between i440fx and q35. Provides a default
64-bit base, which starts beyond the cold-plugged 64-bit RAM, and skips
the DIMM hotplug area too (if any).
- i440fx_pcihost_get_pci_hole64_start(), q35_host_get_pci_hole64_start():
board-specific 64-bit base property getters called abstractly by the
ACPI generator. Both of these fall back to pc_pci_hole64_start() if the
firmware didn't program any 64-bit hole (i.e. if the firmware didn't
assign a 64-bit GPA to any MMIO BAR on any device). Otherwise, they
honor the firmware's BAR assignments (i.e., they treat the lowest 64-bit
GPA programmed by the firmware as the base address for the aperture).
- i440fx_pcihost_get_pci_hole64_end(), q35_host_get_pci_hole64_end():
these intended to extend the aperture to our size recommendation,
calculated relative to the base of the aperture.
Despite the original intent, i440fx_pcihost_get_pci_hole64_end() and
q35_host_get_pci_hole64_end() currently only extend the aperture relative
to the default base (pc_pci_hole64_start()), ignoring any programming done
by the firmware. This means that our size recommendation may not be met.
Fix it by honoring the firmware's address assignments.
The strange extension sizes were spotted by Alex, in the log of a guest
kernel running on top of OVMF (which prefers to assign 64-bit GPAs to
64-bit BARs).
This change only affects DSDT generation, therefore no new compat property
is being introduced.

Currently, the amdvi_validate_dte() assumes that a valid DTE will
always have V=1. This is not true. The V=1 means that bit[127:1] are
valid. A valid DTE can have IV=1 and V=0 (i.e address translation
disabled and interrupt remapping enabled)
Remove the V=1 check from amdvi_validate_dte(), make the caller
responsible to check for V or IV bits.
This also fixes a bug in existing code that when error is
detected during the translation we'll fail the translation
instead of assuming a passthrough mode.

Without this patch, QEMU will crash if we do these steps:
(1) start QEMU with VT-d IOMMU and two 10G NICs (ixgbe)
(2) bind the NICs with vfio-pci in the guest
(3) start testpmd with the NICs applied
(4) stop testpmd
(5) rebind the NIC back to ixgbe kernel driver

QEMU is not handling the global DMAR switch well, especially when from
"on" to "off".
Let's first take the example of system reset.
Assuming that a guest has IOMMU enabled. When it reboots, we will drop
all the existing DMAR mappings to handle the system reset, however we'll
still keep the existing memory layouts which has the IOMMU memory region
enabled. So after the reboot and before the kernel reloads again, there
will be no mapping at all for the host device. That's problematic since
any software (for example, SeaBIOS) that runs earlier than the kernel
after the reboot will assume the IOMMU is disabled, so any DMA from the
software will fail.
For example, a guest that boots on an assigned NVMe device might fail to
find the boot device after a system reboot/reset and we'll be able to
observe SeaBIOS errors if we capture the debugging log:
WARNING - Timeout at nvme_wait:144!
Meanwhile, we should see DMAR errors on the host of that NVMe device.
It's the DMA fault that caused a NVMe driver timeout.
The correct fix should be that we do proper switching of device DMA
address spaces when system resets, which will setup correct memory
regions and notify the backend of the devices. This might not affect
much on non-assigned devices since QEMU VT-d emulation will assume a
default passthrough mapping if DMAR is not enabled in the GCMD
register (please refer to vtd_iommu_translate). However that's required
for an assigned devices, since that'll rebuild the correct GPA to HPA
mapping that is needed for any DMA operation during guest bootstrap.
Besides the system reset, we have some other places that might change
the global DMAR status and we'd better do the same thing there. For
example, when we change the state of GCMD register, or the DMAR root
pointer. Do the same refresh for all these places. For these two
places we'll also need to explicitly invalidate the context entry cache
and iotlb cache.

Add a virtual Xilinx Versal board.
This board is based on the Xilinx Versal SoC. The exact
details of what peripherals are attached to this board
will remain in control of QEMU. QEMU will generate an
FDT on the fly for Linux and other software to auto-discover
peripherals.

SA-1100/SA-1110 device are reserved. Setting them may lead to
OOB 's->handler[]' array access issue. Mask off [31:28] bits to

According to qdev-properties.h, properties of pointer type should

See qemu_spice_add_display_interface(), the console index is also used
as channel id. So put that into the qxl->id field too.
In typical use cases (one primary qxl-vga device, optionally one or more
secondary qxl devices, no non-qxl display devices) this doesn't change
anything.
With this in place the qxl->id can not be used any more to figure
whenever a given device is primary (with vga compat mode) or secondary.
So add a bool to track this.
