The tutorial doesn't match reality since at least 2013. Repairing it
involves fixing the following issues:
* Update for commit 6d327171551 (aio / timers: Remove alarm timers):
replace the broken examples. Instead of having one for returning a
struct and another for returning a list of structs, do just one for
the latter. This resolves the FIXME added in commit
e218052f928 (aio / timers: De-document -clock) back in 2014.
* Update for commit 895a2a80e0e (qapi: Use 'struct' instead of 'type'
in schema).
* Update for commit 3313b6124b5 (qapi: add qapi2texi script): add
required documentation to the schema snippets, and drop section
"Command Documentation".
* Update for commit a3c45b3e629 (qapi: New special feature flag
"unstable"): supply the required feature, deemphasize the x- prefix.
* Update for commit dd98234c059 (qapi: introduce x-query-roms QMP
command): rephrase from "add new command" to "examine existing
command".
* Update for commit 9492718b7c0 (qapi misc: Elide redundant has_FOO in
generated C): hello-world's message argument no longer comes with a
has_message, add a second argument that does.
* Update for moved and renamed files.

Add a new migration capability 'mapped-ram'.
The core of the feature is to ensure that RAM pages are mapped
directly to offsets in the resulting migration file instead of being
streamed at arbitrary points.
The reasons why we'd want such behavior are:
- The resulting file will have a bounded size, since pages which are
dirtied multiple times will always go to a fixed location in the
file, rather than constantly being added to a sequential
stream. This eliminates cases where a VM with, say, 1G of RAM can
result in a migration file that's 10s of GBs, provided that the
workload constantly redirties memory.
- It paves the way to implement O_DIRECT-enabled save/restore of the
migration stream as the pages are ensured to be written at aligned
offsets.
- It allows the usage of multifd so we can write RAM pages to the
migration file in parallel.
For now, enabling the capability has no effect. The next couple of
patches implement the core functionality.

This option controls the host page size. From the mis-usage in
our own testsuite, this is easily confused with guest page size.
The only thing that occurs when changing the host page size is
that stuff breaks, because one cannot actually change the host
page size. Therefore reject all but the no-op setting as part
of the deprecation process.

With the new plugin register API we can now track changes to register
values. Currently the implementation is fairly dumb which will slow
down if a large number of register values are being tracked. This
could be improved by only instrumenting instructions which mention
registers we are interested in tracking.
Example usage:
./qemu-aarch64 -D plugin.log -d plugin \
-cpu max,sve256=on \
-plugin contrib/plugins/libexeclog.so,reg=sp,reg=z\* \
./tests/tcg/aarch64-linux-user/sha512-sve
will display in the execlog any changes to the stack pointer (sp) and
the SVE Z registers.
As testing registers every instruction will be quite a heavy operation
there is an additional flag which attempts to optimise the register
tracking by only instrumenting instructions which are likely to change
its value. This relies on the QEMU disassembler showing up the register
names in disassembly so is an explicit opt-in.

We have an OBJECT_DEFINE_TYPE_EXTENDED macro, plus several variations
on it, which emits the boilerplate for the TypeInfo and ensures it is
registered with the type system. However, all the existing macros
insist that the type being defined has its own FooClass struct, so
they aren't useful for the common case of a simple leaf class which
doesn't have any new methods or any other need for its own class
struct (that is, for the kind of type that OBJECT_DECLARE_SIMPLE_TYPE
declares).
Pull the actual implementation of OBJECT_DEFINE_TYPE_EXTENDED out
into a new DO_OBJECT_DEFINE_TYPE_EXTENDED which parameterizes the
value we use for the class_size field. This lets us add a new
OBJECT_DEFINE_SIMPLE_TYPE which does the same job as the various
existing OBJECT_DEFINE_*_TYPE_* family macros for this kind of simple
type, and the variant OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES for
when the type will implement some interfaces.

Previously not all references mentioned any spec version at all.
Given r3.1 is the current specification available for evaluation at
www.computeexpresslink.org update references to refer to that.
Hopefully this won't become a never ending job.
A few structure definitions have been updated to add new fields.
Defaults of 0 and read only are valid choices for these new DVSEC
registers so go with that for now.
There are additional error codes and some of the 'questions' in
the comments are resolved now.
Update documentation reference to point to the CXL r3.1 specification
with naming closer to what is on the cover.
For cases where there are structure version numbers, add defines
so they can be found next to the register definitions.

The QAPI generator forces you to document your stuff. Except for
command arguments, event data, and members of enum and object types:
these the generator silently "documents" as "Not documented".
We can't require proper documentation there without first fixing all
the offenders. We've always had too many offenders to pull that off.
Right now, we have more than 500. Worse, we seem to fix old ones no
faster than we add new ones: in the past year, we fixed 22 ones, but
added 26 new ones.
To help arrest the backsliding, make missing documentation an error
unless the command, type, or event is in listed in new pragma
documentation-exceptions.
List all the current offenders: 117 commands and types in qapi/, and 9
in qga/.

QAPISchemaGenRSTVisitor._nodes_for_members() has a special case to
auto-generate documentation for a union tag member of implicit (enum)
type that lacks documentation.
This was useful for simple unions, where the tag member's type was
implicitly. The only implicit enum type left today is 'QType'. Not
worth a special case. Drop. No change to generated documentation.

This might be premature but while streamlining the avocado tests I
realised the only tests we have are "check-tcg" ones. The ageing
fedora-cris-cross image works well enough for developers but can't be
used in CI as we need supported build platforms to build QEMU.
Does this mean the writing is on the wall for this architecture?

The 'header-rows' directive indicates how many rows in the generated

We can't just embed labels directly into files like qemu-options.hx which
are included from multiple top-level rST files, because Sphinx sees the
labels as duplicate: https://github.com/sphinx-doc/sphinx/issues/9707
So add an optional argument to the SRST directive which causes a label
of the form '.. _DOCNAME-HXFILE-LABEL:' to be emitted, where 'DOCNAME'
is the name of the top level rST file, 'HXFILE' is the filename of the
.hx file, and 'LABEL' is the text provided within the 'SRST()' directive.
Using the DOCNAME of the top-level rST document means that it is unique
even when the .hx file is included from two different documents, as is
the case for qemu-options.hx
Now where the Xen PV documentation refers to the documentation for the
-initrd command line option, it can emit a link directly to it as
'<system/invocation-qemu-options-initrd>'.
