2020-09-29docs/devel/qapi-code-gen.txt: Update to new rST backend conventionsPeter Maydell
Update the documentation of QAPI document comment syntax to match the new rST backend requirements. The principal changes are: * whitespace is now significant, and multiline definitions must have their second and subsequent lines indented to match the first line * general rST format markup is permitted, not just the small set of markup the old texinfo generator handled. For most things (notably bulleted and itemized lists) the old format was the same as rST is. * Specific things that might trip people up: - instead of *bold* and _italic_ rST has **bold** and *italic* - lists need a preceding and following blank line - a lone literal '*' will need to be backslash-escaped to avoid a rST syntax error * the old leading '|' for example (literal text) blocks is replaced by the standard rST '::' literal block. * we support arbitrary levels of sub- and sub-sub-heading, not just a main and sub-heading like the old texinfo generator * lists can now be nested Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20200925162316.21205-18-peter.maydell@linaro.org> Reviewed-by: Markus Armbruster <armbru@redhat.com> [Commit message improved slightly] Signed-off-by: Markus Armbruster <armbru@redhat.com>
2020-09-29meson.build: Make manuals depend on source to Sphinx extensionsPeter Maydell
The automatic dependency handling for Sphinx manuals only makes the output depend on the input documentation files. This means that if you edit the Python source of an extension then the documentation won't be rebuilt. Create a list of all the source files for the extensions and add it to the dependencies for the manuals. This is similar to how we handle the qapi_gen_depends list. Because we don't try to identify which manuals are using which Sphinx extensions, a change to the source of one extension will always rebuild the entire manual set, not merely the manuals which have changed. This is acceptable because we don't change the extensions all that often.

2020-09-29docs/interop: Convert qemu-qmp-ref to rSTPeter Maydell
Convert qemu-qmp-ref to rST format. This includes dropping the plain-text, pdf and info format outputs for this document; as with all our other Sphinx-based documentation, we provide HTML and manpage only. The qemu-qmp-ref.rst is somewhat more stripped down than the .texi was, because we do not (currently) attempt to generate indexes for the commands, events and data types being documented. Again, we drop the direct link from index.html.in now that the QMP ref is part of the interop manual. This commit removes the code from the root meson.build file that handled the various Texinfo-based outputs, because we no longer generate any documentation except for the Sphinx HTML manuals and the manpages, and the code can't handle having an empty list of files to process.. We'll do further cleanup of the remainders of Texinfo support in subsequent commits.

2020-09-29docs/sphinx: Add new qapi-doc Sphinx extensionPeter Maydell
Some of our documentation is auto-generated from documentation comments in the JSON schema. For Sphinx, rather than creating a file to include, the most natural way to handle this is to have a small custom Sphinx extension which processes the JSON file and inserts documentation into the rST file being processed. This is the same approach that kerneldoc and hxtool use.

2020-09-29scripts/qapi/parser.py: improve doc comment indent handlingPeter Maydell
Make the handling of indentation in doc comments more sophisticated, so that when we see a section like: Notes: some text some more text indented line 3 we save it for the doc-comment processing code as: some text some more text indented line 3 and when we see a section with the heading on its own line: Notes: some text some more text indented text we also accept that and save it in the same form. If we detect that the comment document text is not indented as much as we expect it to be, we throw a parse error. (We don't complain about over-indented sections, because for rST this can be legitimate markup.) The golden reference for the doc comment text is updated to remove the two 'wrong' indents; these now form a test case that we correctly stripped leading whitespace from an indented multi-line argument definition. We update the documentation in docs/devel/qapi-code-gen.txt to describe the new indentation rules.

2020-09-23qemu/atomic.h: rename atomic_ to qatomic_Stefan Hajnoczi
clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included <stdatomic.h> via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h and <stdatomic.h> can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \ sort -u >/tmp/changed_identifiers $ for identifier in $(</tmp/changed_identifiers); do sed -i "s%\<$identifier\>%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.

Deprecate our Unicore32 target support: * the Linux kernel dropped support for unicore32 in commit 05119217a9bd199c for its 5.9 release (with rationale in the cover letter: https://lkml.org/lkml/2020/8/3/232 ) * there is apparently no upstream toolchain that can create unicore32 binaries * the maintainer doesn't seem to have made any contributions to QEMU since the port first landed in 2012 * nobody else seems to have made changes to the unicore code except for generic cleanups either Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Daniel P.

2020-09-14target/arm: Remove KVM support for 32-bit Arm hostsPeter Maydell
We deprecated the support for KVM on 32-bit Arm hosts in time for release 5.0, which means that our deprecation policy allows us to drop it in release 5.2. Remove the code. To repeat the rationale from the deprecation note: the Linux kernel dropped support for 32-bit Arm KVM hosts in 5.7. Running 32-bit guests on a 64-bit Arm host remains supported.

2020-09-10plugins: move the more involved plugins to contribAlex Bennée
We have an exploding complexity problem in the testing so lets just move the more involved plugins into contrib. tests/plugins still exist for the basic plugins that exercise the API. We restore the old pre-meson style Makefile for contrib as it also doubles as a guide for out-of-tree plugin builds. While we are at it add some examples to the documentation and a specific plugins build target.

Commit 480324ec8d "docs/qdev-device-use: Clean up the sentences related to -usbdevice" deleted the information on syntax that no longer works. Unfortunately, the resulting text suggests you can configure USB block devices with -drive, and USB network devices with -net, which is misleading. Instead of rephrasing the now misleading text, I'm putting the information back, and just make clear it's about old versions of QEMU.

2020-09-03qapi: enable use of g_autoptr with QAPI typesDaniel P. Berrangé
Currently QAPI generates a type and function for free'ing it: typedef struct QCryptoBlockCreateOptions QCryptoBlockCreateOptions; void qapi_free_QCryptoBlockCreateOptions(QCryptoBlockCreateOptions *obj); This is used in the traditional manner: QCryptoBlockCreateOptions *opts = NULL; opts = g_new0(QCryptoBlockCreateOptions, 1); ....do stuff with opts... qapi_free_QCryptoBlockCreateOptions(opts); Since bumping the min glib to 2.48, QEMU has incrementally adopted the use of g_auto/g_autoptr. This allows the compiler to run a function to free a variable when it goes out of scope, the benefit being the compiler can guarantee it is freed in all possible code ptahs. This benefit is applicable to QAPI types too, and given the seriously long method names for some qapi_free_XXXX() functions, is much less typing. This change thus makes the code generator emit: G_DEFINE_AUTOPTR_CLEANUP_FUNC(QCryptoBlockCreateOptions, qapi_free_QCryptoBlockCreateOptions) The above code example now becomes g_autoptr(QCryptoBlockCreateOptions) opts = NULL; opts = g_new0(QCryptoBlockCreateOptions, 1); ....do stuff with opts... Note, if the local pointer needs to live beyond the scope holding the variable, then g_steal_pointer can be used. This is useful to return the pointer to the caller in the success codepath, while letting it be freed in all error codepaths. return g_steal_pointer(&opts); The crypto/block.h header needs updating to avoid symbol clash now that the g_autoptr support is a standard QAPI feature.
