381d2c36e1 docs: use consistent markup for footnotes
Unfortunately, the definition of the footnote syntax requires
the author to use the awkward escaped space "\ " in the really common
case of "footnote marker at end of word or sentence"; and in fact the rST
documentation's examples of footnote syntax contain only artificial
examples that do *not* use the syntax.  This resulted in ugly rendering
of footnotes throughout QEMU's documentation.  Ensure the space is escaped
whenever the footnote must attach to the preceding word, and also use
a named reference for clarity.

232c3a848e docs: avoid footnotes consisting of just URLs
Replace the footnotes with inline links whenever the footnote text
consists of nothing but the URL.  While at it, make the link texts
consistent in the surrounding areas, for example avoiding usage of
"here" for the link's text.

In the case of acpi-bits.rst this fixes a build failure with Sphinx
8.1.0, because the FOSDEM link was duplicated in the paragraph and the
new version is a lot stricter about unreferenced footnotes.

effb0f7724 docs: fix invalid footnote syntax
All footnotes must come after a separator in reStructuredText.  Fix the
two files in which this does not happen.

This mistake causes the link to be rendered literally:

   ...from the venv itself[#distlib]_. If no...

and is caught by Sphinx 8.1.0 as an unreferenced footnote.

c8e2b6b4d7 chardev: introduce 'reconnect-ms' and deprecate 'reconnect'
The 'reconnect' option only allows to specify the time in seconds,
which is way too long for certain workflows.

We have a lightweight disk backend server, which takes about 20ms to
live update, but due to this limitation in QEMU, previously the guest
disk controller would hang for one second because it would take this
long for QEMU to reinitialize the socket connection.

Introduce a new option called 'reconnect-ms', which is the same as
'reconnect', except the value is treated as milliseconds. These are
mutually exclusive and specifying both results in an error.

'reconnect' is also deprecated by this commit to make it possible to
remove it in the future as to not keep two options that control the
same thing.

73581a041e migration: Deprecate zero-blocks capability
The zero-blocks capability was meant to be used along with the block
migration, which has been removed already in commit eef0bae3a7
("migration: Remove block migration").

Setting zero-blocks is currently a noop, but the outright removal of
the capability would cause and error in case some users are still
setting it. Put the capability through the deprecation process.

e300f4c11d docs/devel: Mention post_load hook restrictions where we document the hook
Accessing another device in a post_load hook is a bad idea, because
the order of device save/restore is not fixed, and so this
cross-device access makes the save/restore non-deterministic.

We previously only flagged up this requirement in the
record-and-replay developer docs; repeat it in the main migration
documentation, where a developer trying to implement a post_load hook
is more likely to see it.

759cbb4ee9 reset: Add RESET_TYPE_WAKEUP
Some devices need to distinguish cold start reset from waking up from a
suspended state. This patch adds new value to the enum, and updates the
i386 wakeup method to use this new reset type.

0d279bec0f contrib/plugins: Add a plugin to generate basic block vectors
SimPoint is a widely used tool to find the ideal microarchitecture
simulation points so Valgrind[2] and Pin[3] support generating basic
block vectors for use with them. Let's add a corresponding plugin to
QEMU too.

Note that this plugin has a different goal with tests/plugin/bb.c.

This plugin creates a vector for each constant interval instead of
counting the execution of basic blocks for the entire run and able to
describe the change of execution behavior. Its output is also
syntactically simple and better suited for parsing, while the output of
tests/plugin/bb.c is more human-readable.

cf2a78cbbb deprecation: don't enable TCG plugins by default on 32 bit hosts
The existing plugins already liberally use host pointer stuffing for
passing user data which will fail when doing 64 bit guests on 32 bit
hosts. We should discourage this by officially deprecating support and
adding another nail to the 32 bit host coffin.

docs/devel/nested-papr.txt is entirely (apart from the initial
paragraph) a partial copy of the kernel documentation
https://docs.kernel.org/arch/powerpc/kvm-nested.html

There's no benefit to the QEMU docs to converting this to rST,
so instead delete it. Anybody needing to know the API and
protocol for the guest to communicate with the hypervisor
to created nested VMs should refer to the authoratitative
documentation in the kernel docs.

b883fb93db roms: Support compile the efi bios for loongarch
Added loongarch UEFI BIOS support to compiled scripts.

  UEFI code images require 16M alignment, flash images require
16M alignment, under the loongarch architecture.This is agreed
upon when the firmware is loaded in QEMU under Loongarch.

  The naming of UEFI under loongarch refers to the x86 and arm naming methods,
and the UEFI image names in x86 and arm are:
edk2-i386-code.fd
edk2-i386-vars.fd
edk2-arm-code.fd
edk2-arm-vars.fd
So on loongarch, we named it:
edk2-loongarch64-code.fd
edk2-loongarch64-vars.fd

cf7f61d13f target/s390: Convert CPU to Resettable interface
Convert the s390 CPU to the Resettable interface.  This is slightly
more involved than the other CPU types were (see commits
9130cade5fc22..d66e64dd006df) because S390 has its own set of
different kinds of reset with different behaviours that it needs to
trigger.

We handle this by adding these reset types to the Resettable
ResetType enum.  Now instead of having an underlying implementation
of reset that is s390-specific and which might be called either
directly or via the DeviceClass::reset method, we can implement only
the Resettable hold phase method, and have the places that need to
trigger an s390-specific reset type do so by calling
resettable_reset().

The other option would have been to smuggle in the s390 reset
type via, for instance, a field in the CPU state that we set
in s390_do_cpu_initial_reset() etc and then examined in the
reset method, but doing it this way seems cleaner.

The motivation for this change is that this is the last caller
of the legacy device_class_set_parent_reset() function, and
removing that will let us clean up some glue code that we added
for the transition to three-phase reset.

cb771ac1f5 meson: Split --enable-sanitizers to --enable-{asan, ubsan}
We do not always want both address and undefined behavior
sanitizers running at the same time.

For the gitlab custom-runners, drop to only --enable-ubsan.
These jobs are not run by default, but as will be obvious in the
next patch, we don't run ASan on x86 either, and it seems wrong
to hold aarch64 and s390x to a different standard.

43e0d14ee0 docs/sphinx: fix extra stuff in TOC after freeform QMP sections
Freeform sections with titles are currently generating a TOC entry for
the first paragraph in the section after the header, which is not what
we want.

(Easiest to observe directly in the QMP reference manual's
"Introduction" section.)

When freeform sections are parsed, we create both a section header *and*
an empty, title-less section. This causes some problems with sphinx's
post-parse tree transforms, see also 2664f317 - this is a similar issue:
Sphinx doesn't like section-less titles and it also doesn't like
title-less sections.

Modify qapidoc.py to parse text directly into the preceding section
title as child nodes, eliminating the section duplication. This removes
the extra text from the TOC.

Only very, very lightly tested: "it looks right at a glance" ™️. I am
still in the process of rewriting qapidoc, so I didn't give it much
deeper thought.
