It's becoming harder to maintain a cross-compiler to test this host
architecture as the old stable Debian 10 ("Buster") moved into LTS
which supports fewer architectures. For now:
- mark it's deprecation in the docs
- downgrade the containers to build TCG tests only
- drop the cross builds from our CI
Users with an appropriate toolchain and user-space can still take
their chances building it.

Let's use a more appropriate wording for this command line and config
file option. The old ones are still accepted for compatibility reasons,
but marked as deprecated now so that it could be removed in a future
version of QEMU.
This change is based on earlier patches from Philippe Mathieu-Daudé,
with the idea for the new option name suggested by BALATON Zoltan.
And while we're at it, replace the "?" in the help text with "help"
since that does not have the problem of conflicting with the wildcard

Since QEMU's platform support policy is based on libvirt's, it
makes sense to mirror these recent changes made to the latter.

Commit cf60ccc330 ("cutils: Introduce bundle mechanism") introduced
a Python script to populate a bundle directory using os.symlink() to
point to the binaries in the pc-bios directory of the source tree.
Commit 882084a04a ("datadir: Use bundle mechanism") removed previous
logic in pc-bios/meson.build to create a link/copy of pc-bios binaries
in the build tree so os.symlink() is the way to go.
However os.symlink() may fail [1] on Windows if an unprivileged Windows
user started the QEMU build process, which results in QEMU executables
generated in the build tree not able to load the default BIOS/firmware
images due to symbolic links not present in the bundle directory.
This commits updates the documentation by adding such caveats for users
who want to build QEMU on the Windows platform.

Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.
It is a general mechanism and can find any files in the installation
tree. The build tree will have a new directory, qemu-bundle, to
represent what files the installation tree would have for reference by
the executables.
Note that it abandons compatibility with Windows older than 8. The
extended support for the prior version, 7 ended more than 2 years ago,
and it is unlikely that someone would like to run the latest QEMU on
such an old system.

This is will be unique within a QEMU instance, but not globally.

Our support statement for Windows currently talks about "Vista / Server
2008" - which is related to the API of Windows, and this is not easy
to understand for the non-technical users. Additionally, glib sets the
_WIN32_WINNT macro to 0x0601 already, which indicates the Windows 7 API,
so QEMU effectively depends on the Windows 7 API, too.
Thus let's bump the _WIN32_WINNT setting in QEMU to the same level as
glib uses and adjust our support statement in the documentation to
something similar that we're using for Linux and the *BSD systems
(i.e. only the two most recent versions), which should hopefully be
easier to understand for the users now.
And since we're nowadays also compile-testing QEMU with MSYS2 on Windows
itself, I think we could mention this build environment here, too.

-audio is used like "-audio pa,model=sb16". It is almost as simple as
-soundhw, but it reuses the -audiodev parsing machinery and attaches an
audiodev to the newly-created device. The main 'feature' is that
it knows about adding the codec device for model=intel-hda, and adding
the audiodev to the codec device.
In the future, it could be extended to support default models or
builtin devices, just like -nic, or even a default backend. For now,
keep it simple.

Like -set and -readconfig, it would not really be too hard to

However, the uses of -writeconfig are substantially more
limited, as it is generally easier to write the configuration

not even try to detect cases where it prints incorrect

Configuring a drive with "if=none" is meant for creation of a backend
only, it should not get automatically assigned to a device frontend.
Use "if=pflash" for the One-Time-Programmable device instead (like
it is e.g. also done for the efuse device in hw/arm/xlnx-zcu102.c).
Since the old way of configuring the device has already been published
with the previous QEMU versions, we cannot remove this immediately, but
have to deprecate it and support it for at least two more releases.

While introducing a non-QemuOpts code path for device creation for JSON
-device, we noticed that QMP device_add doesn't check its input
correctly (accepting arguments that should have been rejected), and that
users may be relying on this behaviour (libvirt did until it was fixed
recently).
Let's use a deprecation period before we fix this bug in QEMU to avoid
nasty surprises for users.

Modern way is using blockdev-add + blockdev-backup, which provides a
lot more control on how target is opened.
As example of drive-backup problems consider the following:
User of drive-backup expects that target will be opened in the same
cache and aio mode as source. Corresponding logic is in
drive_backup_prepare(), where we take bs->open_flags of source.
It works rather bad if source was added by blockdev-add. Assume source
is qcow2 image. On blockdev-add we should specify aio and cache options
for file child of qcow2 node. What happens next:
drive_backup_prepare() looks at bs->open_flags of qcow2 source node.
But there no BDRV_O_NOCAHE neither BDRV_O_NATIVE_AIO: BDRV_O_NOCAHE is
places in bs->file->bs->open_flags, and BDRV_O_NATIVE_AIO is nowhere,
as file-posix parse options and simply set s->use_linux_aio.
The documentation is updated in a minimal way, so that drive-backup is
noted only as a deprecated command, and blockdev-backup used in most of
places.

-watchdog is the same as -device except that it is case insensitive (and it
allows only watchdog devices of course). Now that "-device help" can list
as such the available watchdog devices, we can deprecate it.
Note that even though -watchdog tries to be case insensitive, it fails
at that: "-watchdog i6300xyz" fails with "Unknown -watchdog device",
but "-watchdog i6300ESB" also fails (when the generated -device option
is processed) with an error "'i6300ESB' is not a valid device model name".
For this reason, the documentation update does not mention the case
insensitivity of -watchdog.

The next commit will add feature flags to enum members. There's a
problem, though: query-qmp-schema shows an enum type's members as an
array of member names (SchemaInfoEnum member @values). If it showed
an array of objects with a name member, we could simply add more
members to these objects. Since it's just strings, we can't.
I can see three ways to correct this design mistake:
1. Do it the way we should have done it, plus compatibility goo.
We want a ['SchemaInfoEnumMember'] member in SchemaInfoEnum. Since
changing @values would be a compatibility break, add a new member
@members instead.
@values is now redundant. In my testing, output of
qemu-system-x86_64's query-qmp-schema grows by 11% (18.5KiB).
We can deprecate @values now and drop it later. This will break
outmoded clients. Well-behaved clients such as libvirt are
expected to break cleanly.
2. Like 1, but omit "boring" elements of @member, and empty @member.
@values does not become redundant. @members augments it. Somewhat
cumbersome, but output of query-qmp-schema grows only as we make
enum members non-boring.
There is nothing to deprecate here.
3. Versioned query-qmp-schema.
query-qmp-schema provides either @values or @members. The QMP
client can select which version it wants. There is no redundant
output.
We can deprecate old versions and eventually drop them. This will
break outmoded clients. Breaking cleanly is easier than for 1.
While 1 and 2 operate within the common rules for compatible
evolution apply (section "Compatibility considerations" in
docs/devel/qapi-code-gen.rst), 3 bypasses them. Attractive when
operating within the rules is just too awkward. Not the case here.
This commit implements 1. Libvirt developers prefer it.
Deprecate @values in favour of @members. Since query-qmp-schema
compatibility is pretty fundamental for management applications, an
extended grace period is advised.

In the SMP configuration, we should either provide a topology
parameter with a reasonable value (greater than zero) or just
omit it and QEMU will compute the missing value.
The users shouldn't provide a configuration with any parameter
of it specified as zero (e.g. -smp 8,sockets=0) which could
possibly cause unexpected results in the -smp parsing. So we
deprecate this kind of configurations since 6.2 by adding the
explicit sanity check.

At this moment we only provide one event to report a hotunplug error,
MEM_UNPLUG_ERROR. As of Linux kernel 5.12 and QEMU 6.0.0, the pseries
machine is now able to report unplug errors for other device types, such
as CPUs.
Instead of creating a (device_type)_UNPLUG_ERROR for each new device,
create a generic DEVICE_UNPLUG_GUEST_ERROR event that can be used by all
guest side unplug errors in the future. This event has a similar API as
the existing DEVICE_DELETED event, always providing the QOM path of the
device and dev->id if there's any.
With this new generic event, MEM_UNPLUG_ERROR is now marked as deprecated.
