The '-usbdevice' option is considered as deprecated nowadays and
we might want to remove these options in a future version of QEMU.
So mark this options as deprecated in the documenation and print out
a warning if it is used to tell the user what to use instead.
While we're at it, improve also some other minor USB-related spots
in qemu-options.hx that were not up to date anymore.

We want to support real (i.e. not virtual) channel devices
even for guests that do not support MCSS-E (where guests may
see devices from any channel subsystem image at once). As all
virtio-ccw devices are in css 0xfe (and show up in the default
css 0 for guests not activating MCSS-E), we need an option to
squash both the virtio subchannels and e.g. passed-through
subchannels from their real css (0-3, or 0 for hosts not
activating MCSS-E) into the default css. This will be
exploited in a later patch.

legacy cpu to node mapping is using cpu index values to map
VCPU to node with help of '-numa node,nodeid=node,cpus=x[-y]'
option. However cpu index is internal concept and QEMU users
have to guess /reimplement qemu's logic/ to map it to
a concrete cpu socket/core/thread to make sane CPUs
placement across numa nodes.
This patch allows to map cpu objects to numa nodes using
the same properties as used for cpus with -device/device_add
(socket-id/core-id/thread-id/node-id).
At present valid properties/values to address CPUs could be
fetched using hotpluggable-cpus monitor/qmp command, it will
require user to start qemu twice when creating domain to fetch
possible CPUs for a machine type/-smp layout first and
then the second time with numa explicit mapping for actual
usage. The first step results could be saved and reused to
set/change mapping later as far as machine type/-smp stays
the same.
Proposed impl. supports exact and wildcard matching to
simplify CLI and allow to set mapping for a specific cpu
or group of cpu objects specified by matched properties.
For example:
# exact mapping x86
-numa cpu,node-id=x,socket-id=y,core-id=z,thread-id=n
# exact mapping SPAPR
-numa cpu,node-id=x,core-id=y
# wildcard mapping, all cpu objects that match socket-id=y
# are mapped to node-id=x
-numa cpu,node-id=x,socket-id=y

When using a virtfs root filesystem, the mount_tag needs to be set to
/dev/root. This can be done long-hand as
-fsdev local,id=root,path=/path/to/rootfs,...
-device virtio-9p-pci,fsdev=root,mount_tag=/dev/root
but the -virtfs shortcut cannot be used as it hard-codes the device identifier
to match the mount_tag, and device identifiers may not contain '/':
$ qemu-system-x86_64 -virtfs local,path=/foo,mount_tag=/dev/root,security_model=passthrough
qemu-system-x86_64: -virtfs local,path=/foo,mount_tag=/dev/root,security_model=passthrough: duplicate fsdev id: /dev/root
To support this case using -virtfs, we allow the device identifier to be
specified explicitly when the mount_tag is not suitable:
-virtfs local,id=root,path=/path/to/rootfs,mount_tag=/dev/root,...

* Substantial improvement to the 'powernv' machine type
- Includes an MMIO XICS version
* POWER9 support improvements
- POWER9 guests with KVM
- Partial support for POWER9 guests with TCG
* IOMMU and VFIO improvements
* Assorted minor changes
There are several IPMI patches here that aren't usually in my area of

are for the benefit of the powernv machine type.
This pull request supersedes my 2017-04-26 pull request. This new set

This patch provides a simple FRU support for the BMC simulator. FRUs
are loaded from a file which name is specified in the object
properties, each entry having a fixed size, also specified in the
properties. If the file is unknown or not accessible for some reason,
a unique entry of 1024 bytes is created as a default. Just enough to
start some simulation.
These commands complies with the IPMI spec : "34. FRU Inventory Device

The new command line option -blockdev works like QMP command
blockdev-add.
The option argument may be given in JSON syntax, exactly as in QMP.
Example usage:
-blockdev '{"node-name": "foo", "driver": "raw", "file": {"driver": "file", "filename": "foo.img"} }'
The JSON argument doesn't exactly blend into the existing option
syntax, so the traditional KEY=VALUE,... syntax is also supported,
using dotted keys to do the nesting:
-blockdev node-name=foo,driver=raw,file.driver=file,file.filename=foo.img
This does not yet support lists, but that will be addressed shortly.
Note that calling qmp_blockdev_add() (say via qmp_marshal_block_add())
right away would crash. We need to stash the configuration for later
instead. This is crudely done, and bypasses QemuOpts, even though
storing configuration is what QemuOpts is for. Need to revamp option
infrastructure to support QAPI types like BlockdevOptions.

The PC machines (pc-q35-* pc-i440fx-* pc-* isapc xenfv) automatically
create lsi53c895a SCSI HBAs and SCSI devices to honor -drive if=scsi.
For giggles, try -drive if=scsi,bus=25,media=cdrom --- this makes QEMU
create 25 of them.
lsi53c895a is thoroughly obsolete (PCI Ultra2 SCSI, ca. 2000), and
currently has no maintainer in QEMU. megasas is a better choice,
except with old OSes that lack drivers. virtio-scsi is a much better
choice when you have a driver, but only (newish) Linux comes with one
in the box. There is no good default that works for all guests.
Encourage users to pick a non-obsolete SCSI HBA that works for them by
deprecating -drive if=scsi.

The code which interprets the CLI args to populate the SocketAddress
objects for plain & websockets VNC is quite complex already and will
need further enhancements shortly. Refactor it into separate methods
to avoid vnc_display_open getting even larger. As a side effect of
the refactoring, it is now possible to specify a listen address for
the websocket server explicitly. e.g,
-vnc localhost:5900,websockets=0.0.0.0:8080
will listen on localhost for the plain VNC server, but expose the
websockets VNC server on the public interface. This refactoring
also removes the restriction that prevents enabling websockets
when the plain VNC server is listening on a UNIX socket.

the metasyntatic variables, not including the square brackets and
hyphen.
The semantics of the "cpus" option will be clarified by rewriting
the whole -numa documentation in a follow-up patch.

Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.
Therefore, it should be safe to just drop it from curl's protocol list.
[Jeff Cody: Below is additional summary pulled, with some rewording,
from followup emails between Max and Markus, to explain what
worked and what didn't]
TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero. By default,
that readahead size is 256KB.
Reads starting at a non-zero offset would also have returned data from a
zero offset. It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.
In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.
