Since Linux switched to blk-mq as the default in Linux commit
5c279bd9e406 ("scsi: default to scsi-mq"), virtio-scsi LUNs consume
about 10x as much guest kernel memory.
This commit allows you to choose the virtqueue size for each
virtio-scsi-pci controller like this:
-device virtio-scsi-pci,id=scsi,virtqueue_size=16
The default is still 128 as before. Using smaller virtqueue_size
allows many more disks to be added to small memory virtual machines.
For a 1 vCPU, 500 MB, no swap VM I observed:
With scsi-mq enabled (upstream kernel): 175 disks
-"- ditto -"- virtqueue_size=64: 318 disks
-"- ditto -"- virtqueue_size=16: 775 disks
With scsi-mq disabled (kernel before 5c279bd9e406): 1755 disks
Note that to have any effect, this requires a kernel patch:

Create a new enum so that we can name the IRQ bits, which will make debugging
them a little nicer if we can print them out. Not handled in this patch, but
this will make it possible to get a nice debug printf detailing exactly which
status bits are set, as it can be multiple at any given time.
As a consequence of this patch, it is no longer possible to set multiple IRQ
codes at once, but nothing was utilizing this ability anyway.

When running a pseries-2.2 or older machine type, we get the following
lines in info mtree:
address-space: memory
...
ffffffffffffffff-ffffffffffffffff (prio 0, i/o): alias
pci@800000020000000.mmio64-alias @pci@800000020000000.mmio
ffffffffffffffff-ffffffffffffffff

pci@800000020000000.mmio64-alias @pci@800000020000000.mmio
ffffffffffffffff-ffffffffffffffff
The same thing occurs when running a pseries-2.7 with
-global spapr-pci-host-bridge.mem_win_size=2147483648
This happens because we always create a 64-bit MMIO window, even if
we didn't explicitely requested it (ie, mem64_win_size == 0) and the
32-bit window is below 2GiB. It doesn't seem to have an impact on the
guest though because spapr_populate_pci_dt() doesn't advertise the
bogus windows when mem64_win_size == 0.
Since these memory regions don't induce any state, we can safely
choose to not create them when their address is equal to -1,
without breaking migration from existing setups.

If object_property_get_link() fails then it allocates an error, which
must be freed before returning. The error_get_pretty() function is
merely an accessor to the error message and doesn't free anything.
The error.h header indicates how to do it right:
* Pass an existing error to the caller with the message modified:
* error_propagate(errp, err);

The existing tries to round up the number of pages but @pages is always
calculated as the rounded up value minus one which makes ctz64() always
return 0 and have create.levels always set 1.
This removes wrong "-1" and allows having more than 1 levels. This becomes
handy for >128GB guests with standard 64K pages as this requires blocks
with zone order 9 and the popular limit of CONFIG_FORCE_MAX_ZONEORDER=9

The OV5_MMU_RADIX_300 requires special handling in the CAS negotiation
process. It is cleared from the option vector of the guest before
evaluating the changes and re-added later. But, when testing for a
possible CAS reset :
spapr->cas_reboot = spapr_ovec_diff(ov5_updates,
ov5_cas_old, spapr->ov5_cas);
the bit OV5_MMU_RADIX_300 will each time be seen as removed from the
previous OV5 set, hence generating a reset loop.
Fix this problem by also clearing the same bit in the ov5_cas_old set.

spapr.c in situations where we can get an existing pointer for
the MachineState by either passing it as an argument to the function
or by using other already available pointers.
The following changes were made:
- spapr_node0_size: static function that is called two times:
at spapr_setup_hpt_and_vrma and ppc_spapr_init. In both cases we can
pass an existing MachineState pointer to it.
- spapr_build_fdt: MachineState pointer can be retrieved from
the existing sPAPRMachineState pointer.
- spapr_boot_set: the opaque in the first arg is a sPAPRMachineState
pointer as we can see inside ppc_spapr_init:
qemu_register_boot_set(spapr_boot_set, spapr);
We can get a MachineState pointer from it.
- spapr_machine_device_plug and spapr_machine_device_unplug_request: the
MachineState, sPAPRMachineState, MachineClass and sPAPRMachineClass pointers
can all be retrieved from the HotplugHandler pointer.

This adds a simplistic emulation of the Sun GEM ethernet controller
found in Apple ASICs.
Currently we only support the Apple UniNorth 1.x variant, but the
other Apple or Sun variants should mostly be a matter of adding
PCI IDs options.
We have a very primitive emulation of a single Broadcom 5201 PHY
which is supported by the MacOS driver.
This model brings out-of-the-box networking to MacOS 9, and all
versions of OS X I tried with the mac99 platform.
Further improvements from Mark:
- Remove sungem.h file, moving constants into sungem.c as required
- Switch to using tracepoints for debugging
- Split register blocks into separate memory regions
- Use arrays in SunGEMState to hold register values
- Add state-saving support

The EP108 is the same as the ZCU102, mark it as deprecated as we don't
need two machines.

Add a machine level virtualization property. This defaults to false and can be
set to true using this machine command line argument:
-machine xlnx-zcu102,virtualization=on
This follows what the ARM virt machine does.
This property only applies to the ZCU102 machine. The EP108 machine does
not have this property.

In preperation for future work let's manually create the Xilnx machines.
This will allow us to set properties for the machines in the future.

The EP108 is a early access development board. Now that silicon is in
production people have access to the ZCU102. Let's rename the internal
QEMU files and variables to use the ZCU102.
There is no functional change here as the EP108 is still a valid board
option.

In several places we were unconditionally applying the
nvic_gprio_mask() to a priority value. This is incorrect
if the priority is one of the fixed negative priority
values (for NMI and HardFault), so don't do it.
This bug would have caused both NMI and HardFault to be
considered as the same priority and so NMI wouldn't
correctly preempt HardFault.

Add a new query-memory-size-summary command which provides the
following memory information in bytes:
* base-memory - size of "base" memory specified with command line option -m.
* plugged-memory - amount of memory that was hot-plugged.
If target does not have CONFIG_MEM_HOTPLUG enabled, no
value is reported.

Fixup comments as per Igor's review
Added 'of' from Vadim's reply
Nowdays we use libusb for usb-host, so we don't have different code
for linux vs. bsd any more. So there is little reason to have the
HOST_USB variable, we can just write things directly into the Makefile
and avoid a pointless indirection.
