2020-10-12tools/virtiofsd: add support for --socket-groupAlex Bennée
If you like running QEMU as a normal user (very common for TCG runs) but you have to run virtiofsd as a root user you run into connection problems. Adding support for an optional --socket-group allows the users to keep using the command line.

2020-10-09hmp: Add support for coroutine command handlersKevin Wolf
Often, QMP command handlers are not only called to handle QMP commands, but also from a corresponding HMP command handler. In order to give them a consistent environment, optionally run HMP command handlers in a coroutine, too. The implementation is a lot simpler than in QMP because for HMP, we still block the VM while the coroutine is running.

2020-10-09qapi: Add a 'coroutine' flag for commandsKevin Wolf
This patch adds a new 'coroutine' flag to QMP command definitions that tells the QMP dispatcher that the command handler is safe to be run in a coroutine. The documentation of the new flag pretends that this flag is already used as intended, which it isn't yet after this patch. We'll implement this in another patch in this series.

2020-10-05scripts: add block-coroutine-wrapper.pyVladimir Sementsov-Ogievskiy
We have a very frequent pattern of creating a coroutine from a function with several arguments: - create a structure to pack parameters - create _entry function to call original function taking parameters from struct - do different magic to handle completion: set ret to NOT_DONE or EINPROGRESS or use separate bool field - fill the struct and create coroutine from _entry function with this struct as a parameter - do coroutine enter and BDRV_POLL_WHILE loop Let's reduce code duplication by generating coroutine wrappers. This patch adds scripts/block-coroutine-wrapper.py together with some friends, which will generate functions with declared prototypes marked by the 'generated_co_wrapper' specifier. The usage of new code generation is as follows: 1. define the coroutine function somewhere int coroutine_fn bdrv_co_NAME(...) {...} 2. declare in some header file int generated_co_wrapper bdrv_NAME(...); with same list of parameters (generated_co_wrapper is defined in "include/block/block.h"). 3. Make sure the block_gen_c declaration in block/meson.build mentions the file with your marker function. Still, no function is now marked, this work is for the following commit.

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.

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..

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.

The sentence explaining the deprecation schedule is ambiguous. Make it clear that a feature deprecated in the Nth release is guaranteed to remain available in the N+1th release. Removal can occur in the N+2nd release or later. As an example of this in action, see commit 25956af3fe5dd0385ad8017bc768a6afe41e2a74 ("block: Finish deprecation of 'qemu-img convert -n -o'").

Hyper-V TLFS prior to version 6.0 had a mistake in it: special value '0xffffffff' for CPUID 0x40000004.EBX was called 'never to retry', this looked weird (like why it's not '0' which supposedly have the same effect?) but nobody raised the question.

According to <https://docutils.sourceforge.io/docs/ref/rst/directives.html#parsed-literal>, "inline markup is recognized and there is no protection from parsing. Backslash-escapes may be necessary to prevent unintended parsing". The qemu(1) manual page (formatted with Sphinx 2.2.2) has several overlong lines on my system. A stand-alone backslash at EOL serves as line continuation in a "parsed-literal" block. Therefore, escape the backslashes that we want to appear as such in the formatted documentation.

Deprecate our lm32 target support. Michael Walle (former lm32 maintainer) suggested that we do this in 2019: https://www.mail-archive.com/qemu-devel@nongnu.org/msg605024.html because the only public user of the architecture is the many-years-dead milkymist project. (The Linux port to lm32 was never merged upstream.) In commit 4b4d96c776f552e (March 2020) we marked it as 'orphan' in the MAINTAINERS file, but didn't officially deprecate it.
