2025-03-13scripts/qcow2-to-stdout.py: Add script to write qcow2 images to stdoutAlberto Garcia1-0/+449
This tool converts a disk image to qcow2, writing the result directly to stdout. This can be used for example to send the generated file over the network. This is equivalent to using qemu-img to convert a file to qcow2 and then writing the result to stdout, with the difference that this tool does not need to create this temporary qcow2 file and therefore does not need any additional disk space. Implementing this directly in qemu-img is not really an option because it expects the output file to be seekable and it is also meant to be a generic tool that supports all combinations of file formats and image options. Instead, this tool can only produce qcow2 files with the basic options, without compression, encryption or other features. The input file is read twice. The first pass is used to determine which clusters contain non-zero data and that information is used to create the qcow2 header, refcount table and blocks, and L1 and L2 tables. After all that metadata is created then the second pass is used to write the guest data. By default qcow2-to-stdout.py expects the input to be a raw file, but if qemu-storage-daemon is available then it can also be used to read images in other formats. Alternatively the user can also run qemu-nbd or qemu-storage-daemon manually instead.

create_backend()'s caller catches QAPIError, and returns non-zero exit code on catch.

2025-03-11qapi/parser: add undocumented stub members to all_sectionsJohn Snow1-1/+16
Parser and doc generator cooperate on generating stub documentation for undocumented members. The parser makes up an ArgSection with an empty description, and the doc generator makes up a description. Right now, the made-up ArgSections go into doc.args. However, the new doc generator uses .all_sections, not .args. So put them into .all_sections, too. Insert them right after existing 'member' sections. If there are none, insert directly after the leading section. Doesn't affect the old generator, because that one doesn't use .all_sections.

2025-03-11qapi/source: allow multi-line QAPISourceInfo advancingJohn Snow1-2/+2
This is for the sake of the new rST generator (the "transmogrifier") so we can advance multiple lines on occasion while keeping the generated<-->source mappings accurate. next_line now simply takes an optional n parameter which chooses the number of lines to advance. The next patch will use this when converting section syntax in free-form documentation to more traditional rST section header syntax, which does not always line up 1:1 for line counts. For example: ``` ## # = Section <-- Info is pointing here, "L1" # # Lorem Ipsum ## ``` would be transformed to rST as: ``` ======= <-- L1 Section <-- L1 ======= <-- L1 <-- L2 Lorem Ipsum <-- L3 ``` After consuming the single "Section" line from the source, we want to advance the source pointer to the next non-empty line which requires jumping by more than one line.

2025-03-11qapi: clean up encoding of section kindsJohn Snow1-27/+70
We have several kinds of sections, and to tell them apart, we use Section attribute @tag and also the section object's Python type: type @tag untagged Section None @foo: ArgSection 'foo' Returns: Section 'Returns' Errors: Section 'Errors' Since: Section 'Since' TODO: Section 'TODO' Note: * @foo can be a member or a feature description, depending on context. * tag == 'Since' can be a Since: section or a member or feature description. If it's a Section, it's the former, and if it's an ArgSection, it's the latter. Clean this up as follows. Move the member or feature name to new ArgSection attribute @name, and replace @tag by enum @kind like this: type kind name untagged Section PLAIN @foo: ArgSection MEMBER 'foo' if member or argument ArgSection FEATURE 'foo' if feature Returns: Section RETURNS Errors: Section ERRORS Since: Section SINCE TODO: Section TODO The qapi-schema tests are updated to account for the new section names; "TODO" becomes "Todo" and `None` becomes "Plain" there.

2025-03-11qapi/parser: adjust info location for doc body sectionJohn Snow1-1/+5
Instead of using the info object for the doc block as a whole (which always points to the very first line of the block), update the info pointer for each call to ensure_untagged_section when the existing section is otherwise empty. This way, Sphinx error information will match precisely to where the text actually starts. For example, this patch will move the info pointer for the "Hello!" untagged section ... > ## <-- from here ... > # Hello! <-- ... to here. > ## This doesn't seem to improve error reporting now. It will with the forthcoming QAPI doc transmogrifier. If I stick bad rST into qapi/block-core.json like this: > ## > # @SnapshotInfo: > # > +# rST syntax error: *ahh! > +# > # @id: unique shapshot id > # > # @name: user chosen name The existing code's error message will point to the beginning of the doc comment, which is less than helpful. The transmogrifier's message will point to the erroneous line, but to accomplish this, it needs this patch.

2025-03-07meson.build: default to -gsplit-dwarf for debug infoAlex Bennée1-0/+2
This option is supported by both gcc (since 4.7) and clang (since 7.0). Not only does this make the linkers job easier by reducing the amount of ELF it needs to parse it also reduces the total build size quite considerably. In my case a default build went from 5.8G to 3.9G (vs 1.9G for --disable-debug-info). The --disable-split-debug option allows distros to keep all the info together for ease of packaging.

2025-03-04qapi: pluggable backend code generatorsDaniel P. Berrangé2-35/+108
The 'qapi.backend.QAPIBackend' class defines an API contract for code generators. The current generator is put into a new class 'qapi.backend.QAPICBackend' and made to be the default impl. A custom generator can be requested using the '-k' arg which takes a fully qualified python class name qapi-gen.py -B the.python.module.QAPIMyBackend This allows out of tree code to use the QAPI generator infrastructure to create new language bindings for QAPI schemas. This has the caveat that the QAPI generator APIs are not guaranteed stable, so consumers of this feature may have to update their code to be compatible with future QEMU releases.

2025-03-04binfmt: Add --ignore-family optionAndrea Bolognani1-3/+16
Until now, the script has worked under the assumption that a host CPU can run binaries targeting any CPU in the same family. That's a fair enough assumption when it comes to running i386 binaries on x86_64, but it doesn't quite apply in the general case. For example, while riscv64 CPUs could theoretically run riscv32 applications natively, in practice there exist few (if any?) CPUs that implement the necessary silicon; moreover, even if you had one such CPU, your host OS would most likely not have enabled the necessary kernel bits. This new option gives distro packagers the ability to opt out of the assumption, likely on a per-architecture basis, and make things work out of the box for a larger fraction of their user base. As an interesting side effect, this makes it possible to enable execution of 64-bit binaries on 32-bit CPUs of the same family, which is a perfectly valid use case that apparently hadn't been considered until now.

2025-03-04binfmt: Normalize host CPU architectureAndrea Bolognani1-19/+25
Right now information regarding the family each CPU type belongs to is recorded in two places: the large data table at the top of the script, and the qemu_host_family() function. We can make things better by mapping host CPU architecture to QEMU target in the few cases where the two don't already match and then using the data table to look up the family, same as we're already doing for the guest CPU architecture. Being able to reason in terms of QEMU target regardless of whether we're looking at the host or guest CPU architecture will come in handy to implement upcoming changes. A couple of entries are dropped in the process: BePC and Power Macintosh. I'm quite certain neither of those have ever been reported as CPU architectures by Linux. I believe many more of the entries that are carried forward could be dropped as well, but I don't have the same level of confidence there so I decided to play it safe just in case.

2025-02-28scripts: forbid use of arbitrary SPDX tags besides license identifiersDaniel P. Berrangé1-0/+12
While SPDX-License-Identifier is a well known SPDX tag, there are a great many more besides that[1]. These are mostly focused on making machine readable metadata available to the 'reuse' tool and similar. They cover concepts like author names, copyright owners, and much more. It is even possible to define source file line groups and apply different SPDX tags to regions of code within a file. At this time we're only interested in adopting SPDX for recording the file global licensing info, so detect & reject any other SPDX metadata. If we want to explicitly collect extra data in SPDX format, we can evaluate each data item on its merits when someone wants to propose it at a later date.

We expect all new code to be contributed with the "GPL-2.0-or-later" license tag. Divergence is permitted if the new file is derived from pre-existing code under a different license, whether from elsewhere in QEMU codebase, or outside. Issue a warning if the declared license is not "GPL-2.0-or-later", and an error if the license is not one of the handful of the expected licenses to prevent unintended proliferation.

2025-02-14make-release: don't rely on $CWD when excluding subproject directoriesMichael Roth1-4/+5
The current logic scans qemu.git/subprojects/ from *.wrap files to determine whether or not to include the associated directories in the release tarballs. However, the script assumes that it is being run from the top-level of the source directory, which may not always be the case. In particular, when generating releases via, e.g.: make qemu-9.2.1.tar.xz the $CWD will either be an arbitrary external build directory, or qemu.git/build, and the exclusions will not be processed as expected. Fix this by using the $src parameter passed to the script as the root directory for the various subproject/ paths referenced by this logic. Also, the error case at the beginning of the subproject_dir() will not result in the error message being printed, and will instead produce an error message about "error" not being a valid command. Fix this by using basic shell commands.

The "special_features" field / parameter holds the subset of schema features that are for internal code use. Specifically 'DEPRECATED' and 'UNSTABLE'. This special casing of internal features is going to be removed, so prepare for that by renaming to 'features'. Using a fixed size type is also best practice for bit fields.

2025-02-10qapi: Move and rename qapi/qmp/dispatch.h to qapi/qmp-registry.hDaniel P. Berrangé1-1/+1
The general expectation is that header files should follow the same file/path naming scheme as the corresponding source file. There are various historical exceptions to this practice in QEMU, with one of the most notable being the include/qapi/qmp/ directory. include/qapi/qmp/dispatch.h corresponds mostly to qapi/qmp-registry.c. Move and rename it to include/qapi/qmp-registry.h. Now just qerror.h is left in include/qapi/qmp/. Since it's deprecated & (slowly) getting eliminated anyway, it isn't worth moving.

2025-02-10qapi: Move include/qapi/qmp/ to include/qobject/Daniel P. Berrangé3-4/+4
The general expectation is that header files should follow the same file/path naming scheme as the corresponding source file. There are various historical exceptions to this practice in QEMU, with one of the most notable being the include/qapi/qmp/ directory. Most of the headers there correspond to source files in qobject/. This patch corrects most of that inconsistency by creating include/qobject/ and moving the headers for qobject/ there.

Dumping coroutines don't yet work with coredumps. Let's make it work. We still kept most of the old code because they can be either more flexible, or prettier.

2025-01-15hw/acpi: Add vmclock deviceDavid Woodhouse1-0/+1
The vmclock device addresses the problem of live migration with precision clocks. The tolerances of a hardware counter (e.g. TSC) are typically around ±50PPM. A guest will use NTP/PTP/PPS to discipline that counter against an external source of 'real' time, and track the precise frequency of the counter as it changes with environmental conditions. When a guest is live migrated, anything it knows about the frequency of the underlying counter becomes invalid. It may move from a host where the counter running at -50PPM of its nominal frequency, to a host where it runs at +50PPM. There will also be a step change in the value of the counter, as the correctness of its absolute value at migration is limited by the accuracy of the source and destination host's time synchronization. The device exposes a shared memory region to guests, which can be mapped all the way to userspace. In the first phase, this merely advertises a 'disruption_marker', which indicates that the guest should throw away any NTP synchronization it thinks it has, and start again. Because the region can be exposed all the way to userspace, applications can still use time from a fast vDSO 'system call', and check the disruption marker to be sure that their timestamp is indeed truthful. The structure also allows for the precise time, as known by the host, to be exposed directly to guests so that they don't have to wait for NTP to resync from scratch. The values and fields are based on the nascent virtio-rtc specification, and the intent is that a version (hopefully precisely this version) of this structure will be included as an optional part of that spec. In the meantime, a simple ACPI device along the lines of VMGENID is perfectly sufficient and is compatible with what's being shipped in certain commercial hypervisors.
