I completely botched up the merged[0] rST conversion of this document by
accidentally dropping entire hunks (!) of text. :-( I made it very hard
for reviewers to spot it, as the omitted text was buried deep in the
document. To fix my hatchet job, I reconverted the "SubmitAPatch"
wiki[1] page from scratch and replaced the existing rST with it, while
making sure I incorporated previous feedback.
In summary, in this reconverted edition:
- I did a careful (to the extent my eyes allowed) para-by-para
comparison of the wiki and the rST to make sure I didn't omit
anything accidentally.
- I made sure to work in the cosmetic feedback[2] that Thomas Huth
pointed out in the merged (and botched) edition:
- fix the hyperlinks in "Split up long patches"
- replace ".". with "does not end with a dot" (in "Write a meaningful
commit message" section)
- replace "---" with ``---`` so that it doesn't render as an em-dash
(there were two other occurrences; I fixed those too)
- Use "QEMU" spelling consistently in prose usage
- Add a consistent "refer to git-config" link where appropriate
Thanks to Thomas Huth and Alex Bennée for noticing it on IRC. And sorry
for my sloppiness.

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.

This introduces three different parts of a job designed to run
on a custom runner managed by Red Hat. The goals include:
a) propose a model for other organizations that want to onboard
their own runners, with their specific platforms, build
configuration and tests.
b) bring awareness to the differences between upstream QEMU and the
version available under CentOS Stream, which is "A preview of
upcoming Red Hat Enterprise Linux minor and major releases".
c) because of b), it should be easier to identify and reduce the gap
between Red Hat's downstream and upstream QEMU.
The components of this custom job are:
I) OS build environment setup code:
- additions to the existing "build-environment.yml" playbook
that can be used to set up CentOS/EL 8 systems.
- a CentOS Stream 8 specific "build-environment.yml" playbook
that adds to the generic one.
II) QEMU build configuration: a script that will produce binaries with
features as similar as possible to the ones built and packaged on
CentOS stream 8.
III) Scripts that define the minimum amount of testing that the
binaries built with the given configuration (point II) under the
given OS build environment (point I) should be subjected to.
IV) Job definition: GitLab CI jobs that will dispatch the build/test
jobs (see points #II and #III) to the machine specifically
configured according to #I.

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.

The single backtick markup in ReST is the "default role". Currently,
Sphinx's default role is called "content". Sphinx suggests you can use
the "Any" role instead to turn any single-backtick enclosed item into a
cross-reference.
This is useful for things like autodoc for Python docstrings, where it's
often nicer to reference other types with `foo` instead of the more
laborious :py:meth:`foo`. It's also useful in multi-domain cases to
easily reference definitions from other Sphinx domains, such as
referencing C code definitions from outside of kerneldoc comments.
Before we do that, though, we'll need to turn all existing usages of the
"content" role to inline verbatim markup wherever it does not correctly
resolve into a cross-refernece by using double backticks instead.

around this. To reduce the burden of implementing QMP commands where
there is low expectation of machine usage, requirements for QAPI
modelling are relaxed provided the command is under the "x-" name
prefix.

This illustrates how to add a QMP command returning unstructured text,
following the guidelines added in the previous patch. The example uses
a simplified version of 'info roms'.

Traditionally we have required that newly added QMP commands will model
any returned data using fine grained QAPI types. This is good for
commands that are intended to be consumed by machines, where clear data
representation is very important. Commands that don't satisfy this have
generally been added to HMP only.
In effect the decision of whether to add a new command to QMP vs HMP has
been used as a proxy for the decision of whether the cost of designing a
fine grained QAPI type is justified by the potential benefits.
As a result the commands present in QMP and HMP are non-overlapping
sets, although HMP comamnds can be accessed indirectly via the QMP
command 'human-monitor-command'.
One of the downsides of 'human-monitor-command' is that the QEMU monitor
APIs remain tied into various internal parts of the QEMU code. For
example any exclusively HMP command will need to use 'monitor_printf'
to get data out. It would be desirable to be able to fully isolate the
monitor implementation from QEMU internals, however, this is only
possible if all commands are exclusively based on QAPI with direct
QMP exposure.
The way to achieve this desired end goal is to finese the requirements
for QMP command design. For cases where the output of a command is only
intended for human consumption, it is reasonable to want to simplify
the implementation by returning a plain string containing formatted
data instead of designing a fine grained QAPI data type. This can be
permitted if-and-only-if the command is exposed under the 'x-' name
prefix. This indicates that the command data format is liable to
future change and that it is not following QAPI design best practice.
The poster child example for this would be the 'info registers' HMP
command which returns printf formatted data representing CPU state.
This information varies enourmously across target architectures and
changes relatively frequently as new CPU features are implemented.
It is there as debugging data for human operators, and any machine
usage would treat it as an opaque blob. It is thus reasonable to
expose this in QMP as 'x-query-registers' returning a 'str' field.

Best practice is to use the 'hmp_handle_error' function, not
'monitor_printf' or 'error_report_err'. This ensures that the
message always gets an 'Error: ' prefix, distinguishing it
from normal command output.

-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".

By convention, names starting with "x-" are experimental. The parts
of external interfaces so named may be withdrawn or changed
incompatibly in future releases.
The naming convention makes unstable interfaces easy to recognize.
Promoting something from experimental to stable involves a name
change. Client code needs to be updated. Occasionally bothersome.
Worse, the convention is not universally observed:
* QOM type "input-barrier" has properties "x-origin", "y-origin".
Looks accidental, but it's ABI since 4.2.
* QOM types "memory-backend-file", "memory-backend-memfd",
"memory-backend-ram", and "memory-backend-epc" have a property
"x-use-canonical-path-for-ramblock-id" that is documented to be
stable despite its name.
We could document these exceptions, but documentation helps only
humans. We want to recognize "unstable" in code, like "deprecated".
So support recognizing it the same way: introduce new special feature
flag "unstable". It will be treated specially by the QAPI generator,
like the existing feature flag "deprecated", and unlike regular
feature flags.
This commit updates documentation and prepares tests. The next commit
updates the QAPI schema. The remaining patches update the QAPI
generator and wire up -compat policy checking.
Management applications can then use query-qmp-schema and -compat to
manage or guard against use of unstable interfaces the same way as for
deprecated interfaces.
docs/devel/qapi-code-gen.txt no longer mandates the naming convention.
Using it anyway might help writers of programs that aren't
full-fledged management applications. Not using it can save us
bothersome renames. We'll see how that shakes out.

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.

Right now for xattr remapping, we support types of "prefix", "ok" or "bad".
Type "bad" returns -EPERM on setxattr and hides xattr in listxattr. For
getxattr, mapping code returns -EPERM but getxattr code converts it to -ENODATA.
I need a new semantics where if an xattr is unsupported, then
getxattr()/setxattr() return -ENOTSUP and listxattr() should hide the xattr.
This is needed to simulate that security.selinux is not supported by
virtiofs filesystem and in that case client falls back to some default
label specified by policy.
So add a new type "unsupported" which returns -ENOTSUP on getxattr() and
setxattr() and hides xattrs in listxattr().
For example, one can use following mapping rule to not support
security.selinux xattr and allow others.
"-o xattrmap=/unsupported/all/security.selinux/security.selinux//ok/all///"

Right now meson_options.txt lists about 90 options. Each option
needs code in configure to parse it and pass the option down to Meson as
a -D command-line argument; in addition the default must be duplicated
between configure and meson_options.txt. This series tries to remove
the code duplication by generating the case statement for those --enable
and --disable options, as well as the corresponding help text.
About 80% of the options can be handled completely by the new mechanism.
Eight meson options are not of the --enable/--disable kind. Six more need
to be parsed in configure for various reasons documented in the patch,
but they still have their help automatically generated.
The advantages are:
- less code in configure
- parsing and help is more consistent (for example --enable-blobs was
not supported)
- options are described entirely in one place, meson_options.txt.
This make it more attractive to use Meson options instead of
hand-crafted configure options and config-host.mak
A few options change name: --enable-tcmalloc and --enable-jemalloc
become --enable-malloc={tcmalloc,jemalloc}; --disable-blobs becomes
--disable-install-blobs; --enable-trace-backend becomes
--enable-trace-backends. However, the old names are allowed
for backwards compatibility.

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.

Both qemu and qemu-img use writeback cache mode by default, which is

default, and the default cache mode is not documented.
According to the qemu-nbd(8):
--cache=CACHE
The cache mode to be used with the file. See the
documentation of the emulator's -drive cache=... option for
allowed values.
qemu(1) says:
The default mode is cache=writeback.
So users have no reason to assume that qemu-nbd is using writethough
cache mode. The only hint is the painfully slow writing when using the
defaults.
Looking in git history, it seems that qemu used writethrough in the past
to support broken guests that did not flush data properly, or could not
flush due to limitations in qemu. But qemu-nbd clients can use
NBD_CMD_FLUSH to flush data, so using writethrough does not help anyone.
Change the default cache mode to writback, and document the default and
available values properly in the online help and manual.

Although it is possible to run a specific test using the avocado
command-line, a user may want to use a specific tag while running the
``make check-acceptance`` during the development or debugging.
This allows using the AVOCADO_TAGS environment variable where the user
takes total control of which tests should run based on the tags defined.
This also makes the check-acceptance command flexible to restrict tests
based on tags while running on CI.
e.g.:
AVOCADO_TAGS="foo bar baz" make check-acceptance

Simple unions predate flat unions. Having both complicates the QAPI
schema language and the QAPI generator. We haven't been using simple
unions in new code for a long time, because they are less flexible and
somewhat awkward on the wire.
The previous commits eliminated simple union from the tree. Now drop
them from the QAPI schema language entirely, and update mentions of
"flat union" to just "union".

Although we have long supported 'qemu-img convert -o
backing_file=foo,backing_fmt=bar', the fact that we have a shortcut -B
for backing_file but none for backing_fmt has made it more likely that
users accidentally run into:
qemu-img: warning: Deprecated use of backing file without explicit backing format
when using -B instead of -o. For similarity with other qemu-img
commands, such as create and compare, add '-F $fmt' as the shorthand
for '-o backing_fmt=$fmt'. Update iotest 122 for coverage of both
spellings.

Currently, cpu-models-x86.rst.inc is included in target-i386.rst directly.
To make the toctree more homogeneous when adding more documentation,
include it through a first-class .rst file.
Together with the previous changes to the man page skeletons, this also
frees "===" for the headings, so that cpu-models-x86.rst.inc need not
assume anything about the headings used by target-i386.rst.

Man pages in docs/system use file inclusion heavily. Use headings with
overlines in the main files, so that the same included file work well
from both manuals and man pages.
This style of heading is a bit more heavy-weight, so it is not used by
the other man pages in interop/ and tools/. If in the future they
are changed to use include files, for example to avoid having sections
named "synopsis" or "description", they can switch to --- with overline
as well.

Use a standard heading format for the index.rst file in a directory.
Using overlines makes it clear that individual documents can use e.g.
=== for chapter titles and --- for section titles, as suggested in the
Linux kernel guidelines[1]. They could do it anyway, because documents
included in a toctree are parsed separately and therefore are not tied
to the same conventions for headings. However, keeping some consistency is
useful since sometimes files are included from multiple places.

Documents within a Sphinx manual are separate files and therefore can use
different conventions for headings. However, keeping some consistency is
useful so that included files are easy to get right.
This patch uses a standard heading format for book titles, so that it is
obvious when a file sits at the top level toctree of a book or man page.
The heading is irrelevant for man pages, but keep it consistent as well.
