c7437f0ddb docs/about: Mark the old pc-i440fx-2.0 - 2.3 machine types as deprecated
As we've seen in the past, it's useful for deprecating old machine
types to finally be able to get of legacy code or do other clean-ups
(see e.g. commit ea985d235b that was used to drop the PCI code in
the 128k bios binaries to free some precious space in those binaries).

So let's continue deprecating the oldest pc machine types. QEMU 2.3
has been released 8 years ago, so that's plenty of time since such
machine types have been used by default, thus deprecating pc-i440fx-2.0
up to pc-i440fx-2.3 should be fine nowadays.

e9a54265f5 hw/rdma: Deprecate the pvrdma device and the rdma subsystem
This subsystem is said to be in a bad shape (see e.g. [1], [2]
and [3]), and nobody seems to feel responsible to pick up patches
for this and send them via a pull request. For example there is
a patch for a CVE-worthy bug posted more than half a year ago [4]
which has never been merged. Thus let's mark it as deprecated and
finally remove it unless somebody steps up and improves the code
quality and adds proper regression tests.

8043effd9b target/riscv: deprecate capital 'Z' CPU properties
At this moment there are eleven CPU extension properties that starts
with capital 'Z': Zifencei, Zicsr, Zihintntl, Zihintpause, Zawrs, Zfa,
Zfh, Zfhmin, Zve32f, Zve64f and Zve64d. All other extensions are named
with lower-case letters.

We want all properties to be named with lower-case letters since it's
consistent with the riscv-isa string that we create in the FDT. Having
these 11 properties to be exceptions can be confusing.

Deprecate all of them. Create their lower-case counterpart to be used as
maintained CPU properties. When trying to use any deprecated property a
warning message will be displayed, recommending users to switch to the
lower-case variant:

./build/qemu-system-riscv64 -M virt -cpu rv64,Zifencei=true --nographic
qemu-system-riscv64: warning: CPU property 'Zifencei' is deprecated. Please use 'zifencei' instead

This will give users some time to change their scripts before we remove
the capital 'Z' properties entirely.

f57d5f8004 target/riscv: deprecate the 'any' CPU type
The 'any' CPU type was introduced in commit dc5bd18fa5 ("RISC-V CPU
Core Definition"), being around since the beginning. It's not an easy
CPU to use: it's undocumented and its name doesn't tell users much about
what the CPU is supposed to bring. 'git log' doesn't help us either in
knowing what was the original design of this CPU type.

The closest we have is a comment from Alistair [1] where he recalls from
memory that the 'any' CPU is supposed to behave like the newly added
'max' CPU. He also suggested that the 'any' CPU should be removed.

The default CPUs are rv32 and rv64, so removing the 'any' CPU will have
impact only on users that might have a script that uses '-cpu any'.
And those users are better off using the default CPUs or the new 'max'
CPU.

We would love to just remove the code and be done with it, but one does
not simply remove a feature in QEMU. We'll put the CPU in quarantine
first, letting users know that we have the intent of removing it in the
future.

69a802792a audio: remove QEMU_AUDIO_* and -audio-help support
These have been deprecated for a long time, and the introduction of
-audio in 7.1.0 has cemented the new way of specifying an audio backend's
parameters.  However, there is still a need for simple configuration
of the audio backend in the desktop case; therefore, if no audiodev is
passed to audio_init(), go through a bunch of simple Audiodev* structures
and pick the first that can be initialized successfully.

The only QEMU_AUDIO_* option that is left in, waiting for a better idea,
is QEMU_AUDIO_DRV=none which is used by qtest.

Remove all the parsing code, including the concept of "can_be_default"
audio drivers: now that audio_prio_list[] is only used in a single place,
wav can be excluded directly in that function.

b91b0fc163 accel: Remove HAX accelerator
HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort
HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark
HAXM in QEMU as deprecated"), released in v8.0.0.

Per the latest HAXM release (v7.8 [*]), the latest QEMU supported
is v7.2:

  Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0.

The next commit (https://github.com/intel/haxm/commit/da1b8ec072)
added:

  HAXM v7.8.0 is our last release and we will not accept
  pull requests or respond to issues after this.

It became very hard to build and test HAXM. Its previous
maintainers made it clear they won't help.  It doesn't seem to be
a very good use of QEMU maintainers to spend their time in a dead
project. Save our time by removing this orphan zombie code.

    migration: do not sent zero pages in bulk stage

    during bulk stage of ram migration if a page is a
    zero page do not send it at all.
    the memory at the destination reads as zero anyway.

    even if there is an madvise with QEMU_MADV_DONTNEED
    at the target upon receipt of a zero page I have observed
    that the target starts swapping if the memory is overcommitted.
    it seems that the pages are dropped asynchronously.

    this patch also updates QMP to return the number of
    skipped pages in MigrationStats.

but removed its usage in 1.5.3

commit 9ef051e553
Author: Peter Lieven <pl@kamp.de>
Date:   Mon Jun 10 12:14:19 2013 +0200

    Revert "migration: do not sent zero pages in bulk stage"

    Not sending zero pages breaks migration if a page is zero
    at the source but not at the destination. This can e.g. happen
    if different BIOS versions are used at source and destination.
    It has also been reported that migration on pseries is completely
    broken with this patch.

    This effectively reverts commit f1c72795af.

So let's start moving more switches into this option group, starting

adacc814f5 hw/cxl: Multi-Region CXL Type-3 Devices (Volatile and Persistent)
This commit enables each CXL Type-3 device to contain one volatile
memory region and one persistent region.

Two new properties have been added to cxl-type3 device initialization:
    [volatile-memdev] and [persistent-memdev]

The existing [memdev] property has been deprecated and will default the
memory region to a persistent memory region (although a user may assign
the region to a ram or file backed region). It cannot be used in
combination with the new [persistent-memdev] property.

Partitioning volatile memory from persistent memory is not yet supported.

Volatile memory is mapped at DPA(0x0), while Persistent memory is mapped
at DPA(vmem->size), per CXL Spec 8.2.9.8.2.0 - Get Partition Info.

In commit 5242876f37 we deprecated the dtb-kaslr-seed property of
the virt board, but forgot the "since n.n" tag in the documentation
of this in deprecated.rst.

This deprecation note first appeared in the 7.1 release, so
retrospectively add the correct "since 7.1" annotation to it.

34c18203d4 qmp: Deprecate 'singlestep' member of StatusInfo
The 'singlestep' member of StatusInfo has never done what the QMP
documentation claims it does.  What it actually reports is whether
TCG is working in "one guest instruction per translation block" mode.

We no longer need this field for the HMP 'info status' command, as
we've moved that information to 'info jit'.  It seems unlikely that
anybody is monitoring the state of this obscure TCG setting via QMP,
especially since QMP provides no means for changing the setting.  So
simply deprecate the field, without providing any replacement.

Until we do eventually delete the member, correct the misstatements
in the QAPI documentation about it.

If we do find that there are users for this, then the most likely way
we would provide replacement access to the information would be to
put the accelerator QOM object at a well-known path such as
/machine/accel, which could then be used with the existing qom-set
and qom-get commands.

e9ccfdd91d hmp: Add 'one-insn-per-tb' command equivalent to 'singlestep'
The 'singlestep' HMP command is confusing, because it doesn't
actually have anything to do with single-stepping the CPU.  What it
does do is force TCG emulation to put one guest instruction in each
TB, which can be useful in some situations.

Create a new HMP command  'one-insn-per-tb', so we can document that
'singlestep' is just a deprecated synonym for it, and eventually
perhaps drop it.

We aren't obliged to do deprecate-and-drop for HMP commands,
but it's easy enough to do so, so we do.

8635a3a153 Revert "docs/about/deprecated: Deprecate 32-bit arm hosts for system emulation"
This reverts commit 1d0a8eba38.

The commit made the wrong assumption that 64-bit distros are most
common these days on arm devices, but as Liviu Ionescu pointed out,
the recommended OS for the very popular Raspberry Pi boards is still
the 32-bit variant, and thus likely still used by a lot of people:

 https://www.raspberrypi.com/software/operating-systems/

Thus it's likely still a little bit too early to put this host
environment on the deprecation list and we should wait a little
bit longer 'til 64-bit distros are the predominant ones.

1d0a8eba38 docs/about/deprecated: Deprecate 32-bit arm hosts for system emulation
For running QEMU in system emulation mode, the user needs a rather
strong host system, i.e. not only an embedded low-frequency controller.
All recent beefy arm host machines should support 64-bit now, it's
unlikely that anybody is still seriously using QEMU on a 32-bit arm
CPU, so we deprecate the 32-bit arm hosts here to finally save use
some time and precious CI minutes.
