The current VNC default keyboard delay is 1ms. With that we're constantly
typing faster than the guest receives keyboard events from an XHCI attached
USB HID device.
The default keyboard delay time in the input layer however is 10ms. I don't know
how that number came to be, but empirical tests on some OpenQA driven ARM
systems show that 10ms really is a reasonable default number for the delay.
This patch moves the VNC delay also to 10ms. That way our default is much
safer (good!) and also consistent with the input layer default (also good!).

POSIX says that backslashes in the arguments to 'echo', as well as
any use of 'echo -n' and 'echo -e', are non-portable; it recommends
people should favor 'printf' instead. This is definitely true where
we do not control which shell is running (such as in makefile snippets
or in documentation examples). But even for scripts where we
require bash (and therefore, where echo does what we want by default),
it is still possible to use 'shopt -s xpg_echo' to change bash's
behavior of echo. And setting a good example never hurts when we are
not sure if a snippet will be copied from a bash-only script to a
general shell script (although I don't change the use of non-portable
\e for ESC when we know the running shell is bash).
Replace 'echo -n "..."' with 'printf %s "..."', and 'echo -e "..."'
with 'printf %b "...\n"', with the optimization that the %s/%b
argument can be omitted if the string being printed is a strict
literal with no '%', '$', or '`' (we could technically also make
this optimization when there are $ or `` substitutions but where
we can prove their results will not be problematic, but proving
that such substitutions are safe makes the patch less trivial
compared to just being consistent).
In the qemu-iotests check script, fix unusual shell quoting
that would result in word-splitting if 'date' outputs a space.
In test 051, take an opportunity to shorten the line.
In test 068, get rid of a pointless second invocation of bash.

In mapped security modes, files are created with very restrictive
permissions (600 for files and 700 for directories). This makes
file sharing between virtual machines and users on the host rather
complicated. Imagine eg. a group of users that need to access data
produced by processes on a virtual machine. Giving those users access
to the data will be difficult since the group access mode is always 0.
This patch makes the default mode for both files and directories
configurable. Existing setups that don't know about the new parameters
keep using the current secure behavior.

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

-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

* 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
maintenance, but there isn't a regular maintainer and these patches
are for the benefit of the powernv machine type.
This pull request supersedes my 2017-04-26 pull request. This new set
fixes a bug in one of the aforementioned IPMI patches which caused

- 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
maintenance, but there isn't a regular maintainer and these patches
are for the benefit of the powernv machine type.
This pull request supersedes my 2017-04-26 pull request. This new set
fixes a bug in one of the aforementioned IPMI patches which caused
clang sanitizer failures (and may have crashed on some libc / host
versions).

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
Commands".

The IPMI BMC simulator populates the sdr/sensor tables with a minimal
set of entries (Watchdog). But some qemu platforms might want to use
extra entries for their custom needs.
This patch modifies slighty the initializing routine to take into
account a larger set read from a file. The name of the file to use is
defined through a new 'sdr' property of the simulator device.

This patch adds a command-line option (-xen-domid-restrict) which will
use the new libxendevicemodel API to restrict devicemodel [1] operations
to the specified domid. (Such operations are not applicable to the xenpv
machine type).
This patch also adds a tracepoint to allow successful enabling of the
restriction to be monitored.
[1] I.e. operations issued by libxendevicemodel. Operation issued by other
xen libraries (e.g. libxenforeignmemory) are currently still unrestricted
but this will be rectified by subsequent patches.

Occasionally the users try to mix the bootindex properties with the
"-boot order" parameter - and this likely does not give the expected
results. So let's add a proper statement that these two concepts
should not be used together.

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.

This patchset adds the throttle support for the 9p-local driver.
For now this functionality can be enabled only through qemu cli options.
QMP interface and support to other drivers need further extensions.
To make it simple for other 9p drivers, the throttle code has been put in
separate files.

We know there will be cases where MTTCG won't work until additional work
is done in the front/back ends to support. It will however be useful to
be able to turn it on.
As a result MTTCG will default to off unless the combination is
supported. However the user can turn it on for the sake of testing.
