2021-01-23qemu-option: warn for short-form boolean optionsPaolo Bonzini
Options such as "server" or "nowait", that are commonly found in -chardev, are sugar for "server=on" and "wait=off". This is quite surprising and also does not have any notion of typing attached. It is even possible to do "-device e1000,noid" and get a device with "id=off". Deprecate it and print a warning when it is encountered. In general, this short form for boolean options only seems to be in wide use for -chardev and -spice. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-01-23hmp: remove "change vnc TARGET" commandPaolo Bonzini
The HMP command \"change vnc TARGET\" is messy: - it takes an ugly shortcut to determine if the option has an "id", with incorrect results if "id=" is not preceded by an unescaped comma. - it deletes the existing QemuOpts and does not try to rollback if the parsing fails (which is not causing problems, but only due to how VNC options are parsed) - because it uses the same parsing function as "-vnc", it forces the latter to not support "-vnc help". On top of this, it uses a deprecated QMP command, thus getting in the way of removing the QMP command. Since the usecase for the command is not clear, just remove it and send "change vnc password" directly to the QMP "change-vnc-password" command.

2021-01-19docs: Build and install all the docs in a single manualPeter Maydell
When we first converted our documentation to Sphinx, we split it into multiple manuals (system, interop, tools, etc), which are all built separately. The primary driver for this was wanting to be able to avoid shipping the 'devel' manual to end-users. However, this is working against the grain of the way Sphinx wants to be used and causes some annoyances: * Cross-references between documents become much harder or possibly impossible * There is no single index to the whole documentation * Within one manual there's no links or table-of-contents info that lets you easily navigate to the others * The devel manual doesn't get published on the QEMU website (it would be nice to able to refer to it there) Merely hiding our developer documentation from end users seems like it's not enough benefit for these costs. Combine all the documentation into a single manual (the same way that the readthedocs site builds it) and install the whole thing. The previous manual divisions remain as the new top level sections in the manual. * The per-manual conf.py files are no longer needed * The man_pages[] specifications previously in each per-manual conf.py move to the top level conf.py * docs/meson.build logic is simplified as we now only need to run Sphinx once for the HTML and then once for the manpages5B * The old index.html.in that produced the top-level page with links to each manual is no longer needed Unfortunately this means that we now have to build the HTML documentation into docs/manual in the build tree rather than directly into docs/; otherwise it is too awkward to ensure we install only the built manual and not also the dependency info, stamp file, etc. The manual still ends up in the same place in the final installed directory, but anybody who was consulting documentation from within the build tree will have to adjust where they're looking.

2021-01-19target/arm: Add cpu properties to control pauthRichard Henderson
The crypto overhead of emulating pauth can be significant for some workloads. Add two boolean properties that allows the feature to be turned off, on with the architected algorithm, or on with an implementation defined algorithm. We need two intermediate booleans to control the state while parsing properties lest we clobber ID_AA64ISAR1 into an invalid intermediate state.

2021-01-12hw/misc: Add a PWM module for NPCM7XXHao Wu
The PWM module is part of NPCM7XX module. Each NPCM7XX module has two identical PWM modules. Each module contains 4 PWM entries. Each PWM has two outputs: frequency and duty_cycle. Both are computed using inputs from software side. This module does not model detail pulse signals since it is expensive. It also does not model interrupts and watchdogs that are dependant on the detail models. The interfaces for these are left in the module so that anyone in need for these functionalities can implement on their own. The user can read the duty cycle and frequency using qom-get command.

2021-01-04clock: Introduce clock_ticks_to_ns()Peter Maydell
The clock_get_ns() API claims to return the period of a clock in nanoseconds. Unfortunately since it returns an integer and a clock's period is represented in units of 2^-32 nanoseconds, the result is often an approximation, and calculating a clock expiry deadline by multiplying clock_get_ns() by a number-of-ticks is unacceptably inaccurate. Introduce a new API clock_ticks_to_ns() which returns the number of nanoseconds it takes the clock to make a given number of ticks. This function can do the complete calculation internally and will thus give a more accurate result.

2020-12-19qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake
Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

2020-12-18docs: add qemu-storage-daemon(1) man pageStefan Hajnoczi
Document the qemu-storage-daemon tool. Most of the command-line options are identical to their QEMU counterparts. Perhaps Sphinx hxtool integration could be extended to extract documentation for individual command-line options so they can be shared. For now the qemu-storage-daemon simply refers to the qemu(1) man page where the command-line options are identical.

2020-12-14target/ppc: Remove "compat" property of server class POWER CPUsGreg Kurz
This property has been deprecated since QEMU 5.0 by commit 22062e54bb68. We only kept a legacy hack that internally converts "compat" into the official "max-cpu-compat" property of the pseries machine type. According to our deprecation policy, we could have removed it for QEMU 5.2 already. Do it now ; since ppc_cpu_parse_featurestr() now just calls the generic parent_parse_features handler, drop it as well. Users are supposed to use the "max-cpu-compat" property of the pseries machine type instead.

2020-12-10scripts: kernel-doc: allow passing desired Sphinx C domain dialectMauro Carvalho Chehab
When kernel-doc is called via kerneldoc.py, there's no need to auto-detect the Sphinx version, as the Sphinx module already knows it. So, add an optional parameter to allow changing the Sphinx dialect. As kernel-doc can also be manually called, keep the auto-detection logic if the parameter was not specified. On such case, emit a warning if sphinx-build can't be found at PATH. I ended using a suggestion from Joe for using a more readable regex, instead of using a complex one with a hidden group like: m/^(\d+)\.(\d+)(?:\.?(\d+)?)/ in order to get the optional <patch> argument.
