2023-05-16docs/devel: remind developers to run CI container pipeline when updating imagesAni Sinha
When new dependencies and packages are added to containers, its important to run CI container generation pipelines on gitlab to make sure that there are no obvious conflicts between packages that are being added and those that are already present. Running CI container pipelines will make sure that there are no such breakages before we commit the change updating the containers. Add a line in the documentation reminding developers to run the pipeline before submitting the change. It will also ease the life of the maintainers.

2023-05-10docs/devel/qapi-code-gen: Update doc comment conventionsMarkus Armbruster
The commit before previous relaxed the indentation rules to let us improve the doc comment conventions. This commit changes the written conventions. The next commits will update QAPI schemas to conform to them. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20230428105429.1687850-16-armbru@redhat.com> Reviewed-by: Juan Quintela <quintela@redhat.com>
2023-05-10qapi: Relax doc string @name: description indentation rulesMarkus Armbruster
The QAPI schema doc comment language provides special syntax for command and event arguments, struct and union members, alternate branches, enumeration values, and features: descriptions starting with "@name:". By convention, we format them like this: # @name: Lorem ipsum dolor sit amet, consectetur adipiscing elit, # sed do eiusmod tempor incididunt ut labore et dolore # magna aliqua. Okay for names as short as "name", but we have much longer ones. Their description gets squeezed against the right margin, like this: # @dirty-sync-missed-zero-copy: Number of times dirty RAM synchronization could # not avoid copying dirty pages. This is between # 0 and @dirty-sync-count * @multifd-channels. # (since 7.1) The description text is effectively just 50 characters wide. Easy enough to read, but can be cumbersome to write. The awkward squeeze against the right margin makes people go beyond it, which produces two undesirables: arguments about style, and descriptions that are unnecessarily hard to read, like this one: # @postcopy-vcpu-blocktime: list of the postcopy blocktime per vCPU. This is # only present when the postcopy-blocktime migration capability # is enabled. (Since 3.0) We could instead format it like # @postcopy-vcpu-blocktime: # list of the postcopy blocktime per vCPU. This is only present # when the postcopy-blocktime migration capability is # enabled. (Since 3.0) or, since the commit before previous, like # @postcopy-vcpu-blocktime: # list of the postcopy blocktime per vCPU. This is only present # when the postcopy-blocktime migration capability is # enabled. (Since 3.0) However, I'd rather have # @postcopy-vcpu-blocktime: list of the postcopy blocktime per vCPU. # This is only present when the postcopy-blocktime migration # capability is enabled. (Since 3.0) because this is how rST field and option lists work. To get this, we need to let the first non-blank line after the "@name:" line determine expected indentation. This fills up the indentation pitfall mentioned in docs/devel/qapi-code-gen.rst. A related pitfall still exists. Update the text to show it.

2023-05-09sphinx/qapidoc: Do not emit TODO sections into user manualsMarkus Armbruster
QAPI doc comments are for QMP users: they go into the "QEMU QMP Reference Manual" and the "QEMU Storage Daemon QMP Reference Manual". The doc comment TODO sections are for somebody else, namely for the people who can do: developers. Do not emit them into the user manuals. This elides the following TODOs: * SchemaInfoCommand # TODO: @success-response (currently irrelevant, because it's QGA, not QMP) This is a note to developers adding introspection to the guest agent. It makes no sense to users. * @query-hotpluggable-cpus # TODO: Better documentation; currently there is none. This is a reminder for developers. It doesn't help users. * @device_add # TODO: This command effectively bypasses QAPI completely due to its # "additional arguments" business. It shouldn't have been added to # the schema in this form. It should be qapified properly, or # replaced by a properly qapified command. Likewise. Eliding them is an improvement.

We have two FIXME notes. These FIXMEs are for QAPI developers. They are not useful for QAPI schema developers. They are marked up as admonitions, which makes them look important in generated HTML. Turn them into comments. QAPI developers will still see them (they read and write the .rst). QAPI schema developers may still see them (if they read the .rst instead of the generated .html), but "this is just for QAPI developers" should be more obvious.

2023-04-28qapi: Fix bullet list markup in documentationMarkus Armbruster
Peter Maydell's commit 100cc4fe0f08 explains: rST insists on a blank line before and after a bulleted list [...] Add some extra blank lines in the doc comments so they're acceptable rST input. It missed one in qapi/trace.json. Paolo Bonzini later added another instance in qapi/stats.json, providing further, if unintended, evidence for his quip that rST is the Perl of ASCII-based markups. Both are parsed as ordinary paragraph, resulting in garbled output. John Snow missed the need for a blank line when converting docs/devel/qapi-code-gen.txt to rST. Add the blank lines we need to get the bullet lists recognized as such. Kevin Wolf and Lukas Straub added two more, but indented. Sphinx recognizes them as (indented) bullet lists. The indentation looks slightly off. Insert a blank line and delete the extra indentation. Fixes: 100cc4fe0f0827f8da1a5c05f9c65e2aaa40e03d (qapi: Add blank lines before bulleted lists) Fixes: 467ef823d83e (qmp: add filtering of statistics by target vCPU) Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Vladimir Sementsov-Ogievskiy <vsementsov@yandex-team.ru> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20230425064223.820979-10-armbru@redhat.com> [Fix of docs/devel/qapi-code-gen.rst squashed, commit message adjusted]

2023-04-24qapi: Require boxed for conditional command and event argumentsMarkus Armbruster
The C code generator fails to honor 'if' conditions of command and event arguments. For instance, tests/qapi-schema/qapi-schema-test.json has { 'event': 'TEST_IF_EVENT', 'data': { 'foo': 'TestIfStruct', 'bar': { 'type': ['str'], 'if': 'TEST_IF_EVT_ARG' } }, 'if': { 'all': ['TEST_IF_EVT', 'TEST_IF_STRUCT'] } } Generated tests/test-qapi-events.h fails to honor the TEST_IF_EVT_ARG condition: #if defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) void qapi_event_send_test_if_event(TestIfStruct *foo, strList *bar); #endif /* defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) */ Only uses so far are in tests/. We could fix the generator to emit something like #if defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) void qapi_event_send_test_if_event(TestIfStruct *foo #if defined(TEST_IF_EVT_ARG) , strList *bar #endif ); #endif /* defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) */ Ugly. Calls become similarly ugly. Not worth fixing. Conditional arguments work fine with 'boxed': true, simply because complex types with conditional members work fine. Not worth breaking. Reject conditional arguments unless boxed. Move the tests cases covering unboxed conditional arguments out of tests/qapi-schema/qapi-schema-test.json. Cover boxed conditional arguments there instead.

2023-04-20docs/devel/kconfig.rst: Fix incorrect markupPeter Maydell
In rST markup syntax, the inline markup (*italics*, **bold** and ``monospaced``) must be separated from the surrending text by non-word characters, otherwise it is not interpreted as markup. To force interpretation as markup in the middle of a word, you need to use a backslash-escaped space (which will not appear as a space in the output). Fix a missing backslash-space in this file, which meant that the `` after "select" was output literally and the monospacing was incorrectly extended all the way to the end of the next monospaced word.

2023-03-07qatomic: add smp_mb__before/after_rmw()Paolo Bonzini
On ARM, seqcst loads and stores (which QEMU does not use) are compiled respectively as LDAR and STLR instructions. Even though LDAR is also used for load-acquire operations, it also waits for all STLRs to leave the store buffer. Thus, LDAR and STLR alone are load-acquire and store-release operations, but LDAR also provides store-against-load ordering as long as the previous store is a STLR. Compare this to ARMv7, where store-release is DMB+STR and load-acquire is LDR+DMB, but an additional DMB is needed between store-seqcst and load-seqcst (e.g. DMB+STR+DMB+LDR+DMB); or with x86, where MOV provides load-acquire and store-release semantics and the two can be reordered. Likewise, on ARM sequentially consistent read-modify-write operations only need to use LDAXR and STLXR respectively for the load and the store, while on x86 they need to use the stronger LOCK prefix. In a strange twist of events, however, the _stronger_ semantics of the ARM instructions can end up causing bugs on ARM, not on x86. The problems occur when seqcst atomics are mixed with relaxed atomics. QEMU's atomics try to bridge the Linux API (that most of the developers are familiar with) and the C11 API, and the two have a substantial difference: - in Linux, strongly-ordered atomics such as atomic_add_return() affect the global ordering of _all_ memory operations, including for example READ_ONCE()/WRITE_ONCE() - in C11, sequentially consistent atomics (except for seq-cst fences) only affect the ordering of sequentially consistent operations. In particular, since relaxed loads are done with LDR on ARM, they are not ordered against seqcst stores (which are done with STLR). QEMU implements high-level synchronization primitives with the idea that the primitives contain the necessary memory barriers, and the callers can use relaxed atomics (qatomic_read/qatomic_set) or even regular accesses. This is very much incompatible with the C11 view that seqcst accesses are only ordered against other seqcst accesses, and requires using seqcst fences as in the following example: qatomic_set(&y, 1); qatomic_set(&x, 1); smp_mb(); smp_mb(); ... qatomic_read(&x) ... ... qatomic_read(&y) ... When a qatomic_*() read-modify write operation is used instead of one or both stores, developers that are more familiar with the Linux API may be tempted to omit the smp_mb(), which will work on x86 but not on ARM. This nasty difference between Linux and C11 read-modify-write operations has already caused issues in util/async.c and more are being found. Provide something similar to Linux smp_mb__before/after_atomic(); this has the double function of documenting clearly why there is a memory barrier, and avoiding a double barrier on x86 and s390x systems. The new macro can already be put to use in qatomic_mb_set().

Python 3.6 is at end-of-life. Update the libvirt-ci module to a version that supports overrides for targets and package mappings; this way, QEMU can use the newer versions provided by CentOS 8 (Python 3.8) and OpenSUSE 15.3 (Python 3.9).

2023-02-27docs/devel: update and clarify lcitool instructionsPaolo Bonzini
Shorten a bit the description of what libvirt-ci does, the name of the data files is not relevant at that point. However, the procedures to add new build prerequisites are lacking some information, particularly with respect to regenerating the output test files for lcitool's unit tests. While at it, also update the paths in the libvirt-ci repository. Reviewed-by: Daniel P. Berrangé <berrange@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-02-27meson: fix dependency on qemu-keymapSteve Sistare
When qemu-keymap is not available on the host, and enable-xkbcommon is specified, parallel make fails with: % make clean ... % make -j 32 ... FAILED: pc-bios/keymaps/is ./qemu-keymap -f pc-bios/keymaps/is -l is /bin/sh: ./qemu-keymap: No such file or directory ... many similar messages ... The code always runs find_program, rather than waiting to build qemu-keymap, because it looks for CONFIG_XKBCOMMON in config_host rather than config_host_data. Making serially succeeds, by soft linking files from pc-bios/keymaps, but that is not the desired result for enable-xkbcommon. Examining all occurrences of 'in config_host' for similar bugs shows one instance in the docs, which is also fixed here.
