This works like adding a typical pxb device, except the name is
'pxb-cxl' instead of 'pxb-pcie'. An example command line would be as
follows:
-device pxb-cxl,id=cxl.0,bus="pcie.0",bus_nr=1
A CXL PXB is backward compatible with PCIe. What this means in practice
is that an operating system that is unaware of CXL should still be able
to enumerate this topology as if it were PCIe.
One can create multiple CXL PXB host bridges, but a host bridge can only
be connected to the main root bus. Host bridges cannot appear elsewhere
in the topology.
Note that as of this patch, the ACPI tables needed for the host bridge
(specifically, an ACPI object in _SB named ACPI0016 and the CEDT) aren't
created. So while this patch internally creates it, it cannot be
properly used by an operating system or other system software.
Also necessary is to add an exception to scripts/device-crash-test
similar to that for exiting pxb as both must created on a PCIexpress
host bus.

The mapping between configure and meson is messy for string options,

Meson options such as b_lto or b_coverage.

Now that we are fully switched over to the new QMP library, move it back
over the old namespace. This is being done primarily so that we may
upload this package simply as "qemu.qmp" without introducing confusion
over whether or not "aqmp" is a new protocol or not.
The trade-off is increased confusion inside the QEMU developer
tree. Sorry!
Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp";
not out of necessity, but just to remove any traces of the "aqmp"
name.

With the command line flag -mplt and a recent toolchain, ELF binaries
generated by gcc can obtain EI_ABIVERSION=1, which makes, e.g., gcc
three-stage bootstrap in a mips-unknown-linux-gnu qemu-user chroot
fail since the binfmt-misc magic does not match anymore. Also other
values are technically possible. qemu executes these binaries just
fine, so relax the mask for the EI_ABIVERSION byte at offset 0x08.
In addition, extend magic string to distinguish mips o32 and n32 ABI.
This information is given by the EF_MIPS_ABI2 (0x20) bit in the
e_flags field of the ELF header (a 4-byte value at offset 0x24 for
the here applicable ELFCLASS32).

If there is a failing iotest, the output is currently not logged to
the console anymore. To get this working again, we need to run the
meson test runner with "--print-errorlogs" (and without "--verbose"
due to a current meson bug that will be fixed here:
https://github.com/mesonbuild/meson/commit/c3f145ca2b9f5.patch ).
We could update the "meson test" call in tests/Makefile.include,
but actually it's nicer and easier if we simply do not treat the
iotests as separate test target anymore and integrate them along
with the other test suites. This has the disadvantage of not getting
the detailed progress indication there anymore, but since that was
only working right in single-threaded "make -j1" mode anyway, it's
not a huge loss right now.

We use the nsis.py script to write out an installer script Section
for each emulator executable, so the exact set of Sections depends on
which executables were built. However the part of qemu.nsi which
specifies mouse-over descriptions for each Section still has a
hard-coded and very outdated list (with just i386 and alpha). This
causes two problems. Firstly, if you build the installer for a
configuration where you didn't build the i386 binaries you get
warnings like this:
warning 6000: unknown variable/constant "{Section_i386}" detected, ignoring (macro:_==:1)
warning 6000: unknown variable/constant "{Section_i386w}" detected, ignoring (macro:_==:1)
(this happens in our gitlab CI jobs, for instance).
Secondly, most of the emulators in the generated installer don't have
any mouseover text.
Make nsis.py generate a second output file which has the necessary
MUI_DESCRIPTION_TEXT lines for each Section it creates, so we can
include that at the right point in qemu.nsi to set the mouse-over
text.

At least the current crop of Aarch64 HW can support running 32 bit EL0
code. Before we can build and test we need a minimal set of packages
installed. We can't use "apt build-dep" because it currently gets
confused trying to keep two sets of build-deps installed at once.
Instead we install a minimal set of libraries that will allow us to
continue.

With the current 'qmp-shell' tool developers must first spawn QEMU with
a suitable -qmp arg and then spawn qmp-shell in a separate terminal
pointing to the right socket.
With 'qmp-shell-wrap' developers can ignore QMP sockets entirely and
just pass the QEMU command and arguments they want. The program will
listen on a UNIX socket and tell QEMU to connect QMP to that.
For example, this:
# qmp-shell-wrap -- qemu-system-x86_64 -display none
Is roughly equivalent of running:
# qemu-system-x86_64 -display none -qmp qmp-shell-1234 &
# qmp-shell qmp-shell-1234
Except that 'qmp-shell-wrap' switches the socket peers around so that
it is the UNIX socket server and QEMU is the socket client. This makes
QEMU reliably go away when qmp-shell-wrap exits, closing the server
socket.

The VSS headers are part of standard MS VS SDK, at least since version
15, and probably before that.
They are also included with MinGW, although currently broken.
Let's streamline a bit the options, by not making it so special, and
instead rely on proper system headers configuration or user
--extra-cxxflags. This still requires some extra step to cross-build
with MinGW as described in the meson.build file now.

For a long time, we assumed that libxml2 is necessary for parallels
block format support (block/parallels*). However, this format actually
does not use libxml [*]. Since this is the only user of libxml2 in
whole QEMU tree, we can drop all libxml2 checks and dependencies too.
It is even more: --enable-parallels configure option was the only
option which was silently ignored when it's (fake) dependency
(libxml2) isn't installed.
Drop all mentions of libxml2.
[*] Actually the basis for libxml use were introduced in commit
ed279a06c5 ("configure: add dependency") but the implementation
was never merged:

"meson test" can be asked to run tests verbosely; this makes it usable
also for qemu-iotests's own harness, and it lets "make check-block"
reuse mtest2make.py's infrastructure to find and build test dependencies.
Adjust check-block.sh to use the standard exit code that reports a test
as skipped. Alternatively, in the future we could make it produce TAP
output, which is consistent with all other "make check" tests.

We don't generate trace events for tests/ and qga/ because that it is
not simple and not necessary. We have corresponding comments in both
tests/meson.build and qga/meson.build.
Still to not miss possible future qapi code generation call, and not to
forget to enable trace events generation, let's enable it by default.
So, turn option --gen-trace into opposite --no-trace-events and use new
option only in tests/ and qga/ where we already have good comments why
we don't generate trace events code.
Note that this commit enables trace-events generation for qapi-gen.py
call from tests/qapi-schema/meson.build and storage-daemon/meson.build.
Still, both are kind of noop: tests/qapi-schema/ doesn't seem to
generate any QMP command code and no .trace-events files anyway,
storage-daemon/ uses common QMP command implementations and just
generate empty .trace-events

We are going to generate trace events for QMP commands. We should
generate both trace_*() function calls and trace-events files listing
events for trace generator.
So, add an output module FOO.trace-events for each FOO schema module.
Since we're going to add trace events only to command marshallers,
make the trace-events output optional, so we don't generate so many
useless empty files.
Currently nobody set add_trace_events to True, so new functionality is
disabled. It will be enabled for QAPISchemaGenCommandVisitor

First, this permission never protected a node from being changed, as
generic child-replacing functions don't check it.
Second, it's a strange thing: it presents a permission of parent node
to change its child. But generally, children are replaced by different
mechanisms, like jobs or qmp commands, not by nodes.
Graph-mod permission is hard to understand. All other permissions
describe operations which done by parent node on its child: read,
write, resize. Graph modification operations are something completely
different.
The only place where BLK_PERM_GRAPH_MOD is used as "perm" (not shared
perm) is mirror_start_job, for s->target. Still modern code should use
bdrv_freeze_backing_chain() to protect from graph modification, if we
don't do it somewhere it may be considered as a bug. So, it's a bit
risky to drop GRAPH_MOD, and analyzing of possible loss of protection
is hard. But one day we should do it, let's do it now.
One more bit of information is that locking the corresponding byte in
file-posix doesn't make sense at all.

The handling for the XFS_IOC_DIOINFO ioctl is currently quite excessive:
This is not a "real" feature like the other features that we provide with
the "--enable-xxx" and "--disable-xxx" switches for the configure script,
since this does not influence lots of code (it's only about one call to
xfsctl() in file-posix.c), so people don't gain much with the ability to
disable this with "--disable-xfsctl".
It's also unfortunate that the ioctl will be disabled on Linux in case
the user did not install the right xfsprogs-devel package before running
configure. Thus let's simplify this by providing the ioctl definition
on our own, so we can completely get rid of the header dependency and
thus the related code in the configure script.

The "dbus" display backend exports the QEMU consoles and other
UI-related interfaces over D-Bus.
By default, the connection is established on the session bus, but you
can specify a different bus with the "addr" option.
The backend takes the "org.qemu" service name, while still allowing
further instances to queue on the same name (so you can lookup all the
available instances too). It accepts any number of clients at this
point, although this is expected to evolve with options to restrict
clients, or only accept p2p via fd passing.
The interface is intentionally very close to the internal QEMU API,
and can be introspected or interacted with busctl/dfeet etc:
$ ./qemu-system-x86_64 -name MyVM -display dbus
$ busctl --user introspect org.qemu /org/qemu/Display1/Console_0

Despite all the previous fixes, it's still possible for
device-crash-test to wedge itself in the case that QEMU terminates *so
quickly* that it doesn't even begin a connection attempt to our QMP
client. Python will just joyfully wait ad infinitum for a connection
that will now never arrive.
The real fix is to use asyncio to simultaneously poll both the health of
the launched process AND the connection attempt. That's quite a bit more
invasive than just setting a connection timeout, though.

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.

Under SELinux, Unix domain sockets have two labels. One is on the
disk and can be set with commands such as chcon(1). There is a
different label stored in memory (called the process label). This can
only be set by the process creating the socket. When using SELinux +
SVirt and wanting qemu to be able to connect to a qemu-nbd instance,
you must set both labels correctly first.
For qemu-nbd the options to set the second label are awkward. You can
create the socket in a wrapper program and then exec into qemu-nbd.
Or you could try something with LD_PRELOAD.
This commit adds the ability to set the label straightforwardly on the
command line, via the new --selinux-label flag. (The name of the flag
is the same as the equivalent nbdkit option.)
A worked example showing how to use the new option can be found in

This gains some bugfixes, especially:
- it fixes the introspection of array options. While technically we
still support Meson 0.58.2, this issue only appears when adding a new
option and not if the user is just building QEMU. In the relatively
rare case of a contributor using --meson to point to a 0.58 version,
review can catch spurious changes to scripts/meson-buildoptions.sh
easily.
- it fixes "meson test" when it is not the process group leader. Make is
the process group leader when "make check" invokes "meson test", so this
is a requirement for using it as a test harness.

For now, this covers only syntactic aspects of QMP, i.e. stuff tagged

aspects, or the command line.
Note that there is no good way for management application to detect
presence of these new option parameters: they are not visible output

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.

This happens because the file 'f' is open in binary mode while

The results are human-readable files, 'desc.json' and 'state.json',
so there is no reason to use the binary mode.

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.

Adding static types causes a cycle in the QAPI generator:
[schema -> expr -> parser -> schema]. It exists because the QAPIDoc
class needs the names of types defined by the schema module, but the
schema module needs to import both expr.py/parser.py to do its actual
parsing.
Ultimately, the layering violation is that parser.py should not have any
knowledge of specifics of the Schema. QAPIDoc performs double-duty here
both as a parser *and* as a finalized object that is part of the schema.
In this patch, add the offending type hints alongside the workaround to
avoid the cycle becoming a problem at runtime. See
https://mypy.readthedocs.io/en/latest/runtime_troubles.html#import-cycles
for more information on this workaround technique.
I see three ultimate resolutions here:
(1) Just keep this patch and use the TYPE_CHECKING trick to eliminate
the cycle which is only present during static analysis.
(2) Don't bother to annotate connect_member() et al, give them 'object'
or 'Any'. I don't particularly like this, because it diminishes the
usefulness of type hints for documentation purposes. Still, it's an
extremely quick fix.
(3) Reimplement doc <--> definition correlation directly in schema.py,
integrating doc fields directly into QAPISchemaMember and relieving
the QAPIDoc class of the responsibility. Users of the information
would instead visit the members first and retrieve their
documentation instead of the inverse operation -- visiting the
documentation and retrieving their members.
My preference is (3), but in the short-term (1) is the easiest way to
have my cake (strong type hints) and eat it too (Not have import
cycles). Do (1) for now, but plan for (3).

Here's the weird bit. QAPIDoc generally expects -- virtually everywhere
-- that it will always have a current section. The sole exception to
this is in the case that end_comment() is called, which leaves us with
*no* section. However, in this case, we also don't expect to actually
ever mutate the comment contents ever again.
NullSection is just a Null-object that allows us to maintain the
invariant that we *always* have a current section, enforced by static
typing -- allowing us to type that field as QAPIDoc.Section instead of
the more ambiguous Optional[QAPIDoc.Section].
end_section is renamed to switch_section and now accepts as an argument
the new section to activate, clarifying that no callers ever just
unilaterally end a section; they only do so when starting a new section.

True, we do not check the validity of this symbol -- but we don't check
the validity of definition names during parse, either -- that happens
later, during the expr check. I don't want to introduce a dependency on
expr.py:check_name_str here and introduce a cycle.
Instead, rest assured that a documentation block is required for each
definition. This requirement uses the names of each section to ensure
that we fulfilled this requirement.
e.g., let's say that block-core.json has a comment block for
"Snapshot!Info" by accident. We'll see this error message:
In file included from ../../qapi/block.json:8:
../../qapi/block-core.json: In struct 'SnapshotInfo':
../../qapi/block-core.json:38: documentation comment is for 'Snapshot!Info'
That's a pretty decent error message.
Now, let's say that we actually mangle it twice, identically:
../../qapi/block-core.json: In struct 'Snapshot!Info':
../../qapi/block-core.json:38: struct has an invalid name
That's also pretty decent. If we forget to fix it in both places, we'll
just be back to the first error.
Therefore, let's just drop this FIXME and adjust the error message to
not imply a more thorough check than is actually performed.
