QEMU 5.1 changed the behaviour of the default boot for the RISC-V virt
and sifive_u machines. This patch moves that change from the

143897b501 hw/riscv: microchip_pfsoc: Support direct kernel boot
At present the Microchip Icicle Kit machine only supports using
'-bios' to load the HSS, and does not support '-kernel' for direct
kernel booting just like other RISC-V machines do. One has to use
U-Boot which is chain-loaded by HSS, to load a kernel for testing.
This is not so convenient.

Adding '-kernel' support together with the existing '-bios', we
follow the following table to select which payload we execute:

  -bios |    -kernel | payload
  ------+------------+--------
      N |          N | HSS
      Y | don't care | HSS
      N |          Y | kernel

This ensures backwards compatibility with how we used to expose
'-bios' to users. When '-kernel' is used for direct boot, '-dtb'
must be present to provide a valid device tree for the board,
as we don't generate device tree.

When direct kernel boot is used, the OpenSBI fw_dynamic BIOS image
is used to boot a payload like U-Boot or OS kernel directly.

Documentation is updated to describe the direct kernel boot. Note
as of today there is still no PolarFire SoC support in the upstream
Linux kernel hence the document does not include instructions for
that. It will be updated in the future.

269a7e9786 docs: Fix installation of man pages with Sphinx 4.x
The 4.x branch of Sphinx introduces a breaking change, as generated man
pages are now written to subdirectories corresponding to the manual
section they belong to. This results in `make install` erroring out when
attempting to install the man pages, because they are not where it
expects to find them.

This patch restores the behavior of Sphinx 3.x regarding man pages.

The official punctuation for Arm CPU names uses a hyphen, like
"Cortex-A9". We mostly follow this, but in a few places usage
without the hyphen has crept in. Fix those so we consistently
use the same way of writing the CPU name.

  * Several cleanups to softmmu code
  * Continued progress towards allowing --disable-tcg
  * Fix for the POWER PEF implementation
  * Fix for LPCR handling of hotplugged CPUs
  * Assorted other bugfixes and cleanups
 
 This patchset does contain a couple of changes to code outside my
 normal scope of maintainership, related to the removal of cpu_dump and
 cpu_statistics hooks.  ppc was the last target arch implementing these
 at all, and they didn't really do anything there either.  The patches

d65173f924 Document qemu-img options data_file and data_file_raw
The contents of this patch were initially developed and posted by Han
Han[1], however, it appears the original patch was not applied. Since
then, the relevant documentation has been moved and adapted to a new
format.

I've taken most of the original wording and tweaked it according to
some of the feedback from the original patch submission. I've also
adapted it to restructured text, which is the format the documentation
currently uses.

73e6aec652 sphinx: adopt kernel readthedoc theme
The default "alabaster" sphinx theme has a couple shortcomings:
- the navbar moves along the page
- the search bar is not always at the same place
- it lacks some contrast and colours

The "rtd" theme from readthedocs.org is a popular third party theme used
notably by the kernel, with a custom style sheet. I like it better,
perhaps others do too. It also simplifies the "Edit on Gitlab" links.

Tweak a bit the custom theme to match qemu.org style, use the
QEMU logo, and favicon etc.

875bb7e35b Remove the deprecated moxie target
There are no known users of this CPU anymore, and there are no
binaries available online which could be used for regression tests,
so the code has likely completely bit-rotten already. It's been
marked as deprecated since two releases now and nobody spoke up
that there is still a need to keep it, thus let's remove it now.

f1dfab0d9b hw/arm/mps2-tz: Implement AN524 memory remapping via machine property
The AN524 FPGA image supports two memory maps, which differ in where
the QSPI and BRAM are.  In the default map, the BRAM is at
0x0000_0000, and the QSPI at 0x2800_0000.  In the second map, they
are the other way around.

In hardware, the initial mapping can be selected by the user by
writing either "REMAP: BRAM" (the default) or "REMAP: QSPI" in the
board configuration file.  The board config file is acted on by the
"Motherboard Configuration Controller", which is an entirely separate
microcontroller on the dev board but outside the FPGA.

The guest can also dynamically change the mapping via the SCC
CFG_REG0 register.

Implement this functionality for QEMU, using a machine property
"remap" with valid values "BRAM" and "QSPI" to allow the user to set
the initial mapping, in the same way they can on the FPGA, and
wiring up the bit from the SCC register to also switch the mapping.

46f49468c6 qapi/error: Repurpose QAPIError as an abstract base exception class
Rename QAPIError to QAPISourceError, and then create a new QAPIError
class that serves as the basis for all of our other custom exceptions,
without specifying any class properties.

This leaves QAPIError as a package-wide error class that's suitable for
any current or future errors.

(Right now, we don't have any errors that DON'T also want to specify a
Source location, but this MAY change. In these cases, a common abstract
ancestor would be desired.)

Add docstrings to explain the intended function of each error class.

Document how multicore machines appear to GDB when debugged

the "multiple heterogenous clusters" case, but unfortunately
as far as I know there is no way with the remote protocol
for the stub to tell gdb "I have 2 inferiors, please connect
to both", so the user must set it all up manually.

c81cfb89bc docs: Add a QEMU Code of Conduct and Conflict Resolution Policy document
In an ideal world, we would all get along together very well, always be
polite and never end up in huge conflicts. And even if there are conflicts,
we would always handle each other fair and respectfully. Unfortunately,
this is not an ideal world and sometimes people forget how to interact with
each other in a professional and respectful way. Fortunately, this seldom
happens in the QEMU community, but for such rare cases it is preferrable
to have a basic code of conduct document available to show to people
who are misbehaving.  In case that does not help yet, we should also have
a conflict resolution policy ready that can be applied in the worst case.

The Code of Conduct document tries to be short and to the point while
trying to remain friendly and welcoming; it is based on the Fedora Code
of Conduct[1] with extra detail added based on the Contributor Covenant
1.3.0[2].  Other proposals included the Contributor Covenant 1.3.0 itself
or the Django Code of Conduct[3] (which is also a derivative of Fedora's)
but, in any case, there was agreement on keeping the conflict resolution
policy separate from the CoC itself.

An important point is whether to apply the code of conduct to violations
that occur outside public spaces.  The text herein restricts that to
individuals acting as a representative or a member of the project or
its community.  This is intermediate between the Contributor Covenant
(which only mentions representatives of the community, for example using
an official project e-mail address or posting via an official social media
account), and the Django Code of Conduct, which says that violations of
this code outside these spaces "may" be considered but otherwise applies
no limit.

The conflict resolution policy is based on the Drupal Conflict Resolution
Policy[4] and its derivative, the Mozilla Consequence Ladder[5].

220222a0fe qsd: Document FUSE exports
Implementing FUSE exports required no changes to the storage daemon, so
we forgot to document them there.  Considering that both NBD and
vhost-user-blk exports are documented in its man page (and NBD exports
in its --help text), we should probably do the same for FUSE.

d2aea775d4 usb: Remove "-usbdevice ccid"
"-usbdevice ccid" was not documented and -usbdevice itself was marked
as deprecated before QEMU v6.0. And searching for "-usbdevice ccid"
in the internet does not show any useful results, so likely nobody
was using the ccid device via the -usbdevice option. Remove it now.

561dbb41b1 i386: Make migration fail when Hyper-V reenlightenment was enabled but 'user_tsc_khz' is unset
KVM doesn't fully support Hyper-V reenlightenment notifications on
migration. In particular, it doesn't support emulating TSC frequency
of the source host by trapping all TSC accesses so unless TSC scaling
is supported on the destination host and KVM_SET_TSC_KHZ succeeds, it
is unsafe to proceed with migration.

KVM_SET_TSC_KHZ is called from two sites: kvm_arch_init_vcpu() and
kvm_arch_put_registers(). The later (intentionally) doesn't propagate
errors allowing migrations to succeed even when TSC scaling is not
supported on the destination. This doesn't suit 're-enlightenment'
use-case as we have to guarantee that TSC frequency stays constant.

Require 'tsc-frequency=' command line option to be specified for successful
migration when re-enlightenment was enabled by the guest.

5965243641 char: Deprecate backend aliases 'tty' and 'parport'
QAPI doesn't know the aliases 'tty' and 'parport' and there is no
reason to prefer them to the real names of the backends 'serial' and
'parallel'.

Since warnings are not allowed in 'make check' output, we can't test
the deprecated alias any more. Remove it from test-char.

99b1e64688 qemu-img: Use user_creatable_process_cmdline() for --object
This switches qemu-img from a QemuOpts-based parser for --object to
user_creatable_process_cmdline() which uses a keyval parser and enforces
the QAPI schema.

Apart from being a cleanup, this makes non-scalar properties accessible.

As a side effect, fix wrong exit codes in the object parsing error path
of 'qemu-img compare'. This was broken in commit 334c43e2c3 because
&error_fatal exits with an exit code of 1, while it should have been 2.

Document that exit code 0 is also returned when just requested help was
printed instead of comparing images. This is preexisting behaviour that
isn't changed by this patch, though another instance of it is added with
'--object help'.

39c4c27d37 qapi/qom: Add ObjectOptions for secret*, deprecate 'loaded'
This adds a QAPI schema for the properties of the secret* objects.

The 'loaded' property doesn't seem to make sense as an external
interface: It is automatically set to true in ucc->complete, and
explicitly setting it to true earlier just means that additional options
will be silently ignored.

In other words, the 'loaded' property is useless. Mark it as deprecated
in the schema from the start.

This adds a QAPI schema for the properties of the rng-* objects.

The 'opened' property doesn't seem to make sense as an external

been set to true (i.e. when the object construction has completed), it
can never be reset to false. In other words, the 'opened' property is
useless. Mark it as deprecated in the schema from the start.

The generic 'migrate_set_parameters' command handle all types of param.

Only the QMP commands were documented in the deprecations page, but the
rationale for deprecating applies equally to HMP, and the replacements
exist. Furthermore the HMP commands are just shims to the QMP commands,
so removing the latter breaks the former unless they get re-implemented.

c47c0bcb33 ui: deprecate "password" option for SPICE server

6db34277e3 usb: Un-deprecate -usbdevice (except for -usbdevice audio which gets removed)
When trying to remove the -usbdevice option, there were complaints that
"-usbdevice braille" is still a very useful shortcut for some people.
Thus we never remove this option. Since it's not such a big burden to
keep it around, and it's also convenient in the sense that you don't
have to worry to enable a host controller explicitly with this option,
we should remove it from he deprecation list again.

However, there is one exception: "-usbdevice audio" should go away, since
audio devices without "audiodev=..." parameter are also on the deprecation
list and you cannot use "-usbdevice audio" with "audiodev".

2cc1a90166 Remove deprecated target tilegx
TILE-Gx was only implemented in linux-user mode, but support for this CPU
was removed from the upstream Linux kernel in 2018, and it has also been
dropped from glibc, so there is no new Linux development taking place with

f174cd3350 utils: Deprecate hex-with-suffix sizes
Supporting '0x20M' looks odd, particularly since we have a 'B' suffix
that is ambiguous for bytes, as well as a less-frequently-used 'E'
suffix for extremely large exibytes.  In practice, people using hex
inputs are specifying values in bytes (and would have written
0x2000000, or possibly relied on default_suffix in the case of
qemu_strtosz_MiB), and the use of scaling suffixes makes the most
sense for inputs in decimal (where the user would write 32M).  But
rather than outright dropping support for hex-with-suffix, let's
follow our deprecation policy.  Sadly, since qemu_strtosz() does not
have an Err** parameter, and plumbing that in would be a much larger
task, we instead go with just directly emitting the deprecation
warning to stderr.

cd3a53b727 clock: Add clock_ns_to_ticks() function
Add a clock_ns_to_ticks() function which does the opposite of
clock_ticks_to_ns(): given a duration in nanoseconds, it returns the
number of clock ticks that would happen in that time.  This is useful
for devices that have a free running counter register whose value can
be calculated when it is read.

5ee0abed51 clock: Add ClockEvent parameter to callbacks
The Clock framework allows users to specify a callback which is
called after the clock's period has been updated.  Some users need to
also have a callback which is called before the clock period is
updated.

As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.

Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

e246bf3ddc docs: replace insecure /tmp examples in qsd docs
World-writeable directories have security issues. Avoid showing them in
the documentation since someone might accidentally use them in
situations where they are insecure.

There tend to be 3 security problems:
1. Denial of service. An adversary may be able to create the file
   beforehand, consume all space/inodes, etc to sabotage us.
2. Impersonation. An adversary may be able to create a listen socket and
   accept incoming connections that were meant for us.
3. Unauthenticated client access. An adversary may be able to connect to
   us if we did not set the uid/gid and permissions correctly.

These can be prevented or mitigated with private /tmp, carefully setting
the umask, etc but that requires special action and does not apply to
all situations. Just avoid using /tmp in examples.

3f14b909eb docs: show how to spawn qemu-storage-daemon with fd passing
The QMP monitor, NBD server, and vhost-user-blk export all support file
descriptor passing. This is a useful technique because it allows the
parent process to spawn and wait for qemu-storage-daemon without busy
waiting, which may delay startup due to arbitrary sleep() calls.

This Python example is inspired by the test case written for libnbd by
Richard W.M. Jones <rjones@redhat.com>:

03d2b412aa qemu-storage-daemon: add --pidfile option
Daemons often have a --pidfile option where the pid is written to a file
so that scripts can stop the daemon by sending a signal.

The pid file also acts as a lock to prevent multiple instances of the
daemon from launching for a given pid file.

QEMU, qemu-nbd, qemu-ga, virtiofsd, and qemu-pr-helper all support the
--pidfile option. Add it to qemu-storage-daemon too.

fe636424ca qemu-option: do not suggest using the delay option
The "delay" option was a hack that was introduced to allow writing "nodelay".
We are adding a "nodelay" option to be used as "nodelay=on", so recommend it
instead of "delay".

This is quite ugly, but a proper deprecation of "delay"
cannot be done if QEMU starts suggesting it.  Since it's the
only case I opted for this very much ad-hoc patch.

2c933ac6a8 KVM: x86: deprecate -M kernel-irqchip=off except for -M isapc
The userspace local APIC is basically untested and does not support many
features such as TSC deadline timer, x2APIC or PV spinlocks.  On the
other hand, the PIT and IOAPIC are okay as they are not tied to
the processor and are tested with -M kernel-irqchip=split.

Therefore, deprecate the local APIC and, with it, limit
-M kernel-irqchip=off to the ISA PC machine type, which does not
have a local APIC at all.

e586edcb41 virtiofs: drop remapped security.capability xattr as needed
On Linux, the 'security.capability' xattr holds a set of
capabilities that can change when an executable is run, giving
a limited form of privilege escalation to those programs that
the writer of the file deemed worthy.

Any write causes the 'security.capability' xattr to be dropped,
stopping anyone from gaining privilege by modifying a blessed
file.

Fuse relies on the daemon to do this dropping, and in turn the
daemon relies on the host kernel to drop the xattr for it.  However,
with the addition of -o xattrmap, the xattr that the guest
stores its capabilities in is now not the same as the one that
the host kernel automatically clears.

Where the mapping changes 'security.capability', explicitly clear
the remapped name to preserve the same behaviour.

This bug is assigned CVE-2021-20263.

bc6a3565c8 configure: Improve OpenGL dependency detections
This has the following visible changes:

- GBM is required only for OpenGL dma-buf.
- X11 is explicitly required by gtk-egl.
- EGL is now mandatory for the OpenGL displays.

The last one needs some detailed description. Before this change,
EGL was tested only for OpenGL dma-buf with the check of
EGL_MESA_image_dma_buf_export. However, all of the OpenGL
displays depend on EGL and EGL_MESA_image_dma_buf_export is always
defined by epoxy's EGL interface.
Therefore, it makes more sense to always check the presence of EGL
and say the OpenGL displays are available along with OpenGL dma-buf
if it is present.

a622d64eea plugins: new hwprofile plugin
This is a plugin intended to help with profiling access to various
bits of system hardware. It only really makes sense for system
emulation.

It takes advantage of the recently exposed helper API that allows us
to see the device name (memory region name) associated with a device.

You can specify arg=read or arg=write to limit the tracking to just
reads or writes (by default it does both).

The pattern option:

  -plugin ./tests/plugin/libhwprofile.so,arg=pattern

will allow you to see the access pattern to devices, eg:

  gic_cpu @ 0xffffffc010040000
    off:00000000, 8, 1, 8, 1
    off:00000000, 4, 1, 4, 1
    off:00000000, 2, 1, 2, 1
    off:00000000, 1, 1, 1, 1

The source option:

  -plugin ./tests/plugin/libhwprofile.so,arg=source

will track the virtual source address of the instruction making the
access:

  pl011 @ 0xffffffc010031000
    pc:ffffffc0104c785c, 1, 4, 0, 0
    pc:ffffffc0104c7898, 1, 4, 0, 0
    pc:ffffffc010512bcc, 2, 1867, 0, 0

You cannot mix source and pattern.

Finally the match option allow you to limit the tracking to just the
devices you care about.

94e7787939 hw/i2c: Implement NPCM7XX SMBus Module Single Mode
This commit implements the single-byte mode of the SMBus.

Each Nuvoton SoC has 16 System Management Bus (SMBus). These buses
compliant with SMBus and I2C protocol.

This patch implements the single-byte mode of the SMBus. In this mode,
the user sends or receives a byte each time. The SMBus device transmits
it to the underlying i2c device and sends an interrupt back to the QEMU
guest.

35f15acbc1 docs/sphinx/qapidoc.py: Handle change of QAPI's builtin module name
In commit e2bbc4eaa7 we changed the QAPI modules to name the built-in
module "./builtin" rather than None, but forgot to update the Sphinx
plugin. The effect of this was that when the plugin generated a dependency
file it was including a bogus dependency on a non-existent file named
"builtin", which meant that ninja would run Sphinx and rebuild all
the documentation every time even if nothing had changed.

Update the plugin to use the new name of the builtin module.

Original specification says that l1 table size if 64 * l1_size, which
is obviously wrong. The size of the l1 entry is 64 _bits_, not bytes.
Thus 64 is to be replaces with 8 as specification says about bytes.

There is also minor tweak, field name is renamed from l1 to l1_table,
which matches with the later text.

d7dedf428f meson: accept either shared or static libraries if --disable-static
Meson's "static" argument to cc.find_library is a tri-state.  By default
Meson *prefers* a shared library, which basically means using -l to
look for it; instead, "static: false" *requires* a shared library.  Of
course, "static: true" requires a static library, which is all good
for --enable-static builds.

For --disable-static, "static: false" is rarely desirable; it does not
match what the configure script used to do and the test is more complex
(and harder to debug if it fails, which was reported by Peter Lieven
for librbd).

651615d92d s390: Recognize confidential-guest-support option
At least some s390 cpu models support "Protected Virtualization" (PV),
a mechanism to protect guests from eavesdropping by a compromised
hypervisor.

This is similar in function to other mechanisms like AMD's SEV and
POWER's PEF, which are controlled by the "confidential-guest-support"
machine option.  s390 is a slightly special case, because we already
supported PV, simply by using a CPU model with the required feature
(S390_FEAT_UNPACK).

To integrate this with the option used by other platforms, we
implement the following compromise:

 - When the confidential-guest-support option is set, s390 will
   recognize it, verify that the CPU can support PV (failing if not)
   and set virtio default options necessary for encrypted or protected
   guests, as on other platforms.  i.e. if confidential-guest-support
   is set, we will either create a guest capable of entering PV mode,
   or fail outright.

 - If confidential-guest-support is not set, guests might still be
   able to enter PV mode, if the CPU has the right model.  This may be
   a little surprising, but shouldn't actually be harmful.

To start a guest supporting Protected Virtualization using the new
option use the command line arguments:
    -object s390-pv-guest,id=pv0 -machine confidential-guest-support=pv0

6c8ebe30ea spapr: Add PEF based confidential guest support
Some upcoming POWER machines have a system called PEF (Protected
Execution Facility) which uses a small ultravisor to allow guests to
run in a way that they can't be eavesdropped by the hypervisor.  The
effect is roughly similar to AMD SEV, although the mechanisms are
quite different.

Most of the work of this is done between the guest, KVM and the
ultravisor, with little need for involvement by qemu.  However qemu
does need to tell KVM to allow secure VMs.

Because the availability of secure mode is a guest visible difference
which depends on having the right hardware and firmware, we don't
enable this by default.  In order to run a secure guest you need to
create a "pef-guest" object and set the confidential-guest-support
property to point to it.

Note that this just *allows* secure guests, the architecture of PEF is
such that the guest still needs to talk to the ultravisor to enter
secure mode.  Qemu has no direct way of knowing if the guest is in
secure mode, and certainly can't know until well after machine
creation time.

To start a PEF-capable guest, use the command line options:
    -object pef-guest,id=pef0 -machine confidential-guest-support=pef0

This meson setup also requires a manually-created accel/kvm/trace.h file

e6e80fcfd6 docs: simplify and clarify the platform support rules
The distinction between short life and long life Linux distributions
turned out to be redundant. They can both be covered in a simple way
by noting support will target the current release, and the previous
release for a period of two years or until its EOL. This rule can also
apply to the other UNIX based distros, leaving only Windows needing a
different set of rules.

This also clarifies that Debian LTS is out of scope, because the LTS
support is provided by a separate group from the main Debian maintainer
team.

166310299a os: deprecate the -enable-fips option and QEMU's FIPS enforcement
The -enable-fips option was added a long time ago to prevent the use of
single DES when VNC when FIPS mode is enabled. It should never have been
added, because apps are supposed to unconditionally honour FIPS mode
based on the '/proc/sys/crypto/fips_enabled' file contents.

In addition there is more to achieving FIPS compliance than merely
blocking use of certain algorithms. Those algorithms which are used
need to perform self-tests at runtime.

QEMU's built-in cryptography provider has no support for self-tests,
and neither does the nettle library.

If QEMU is required to be used in a FIPS enabled host, then it must be
built with the libgcrypt library enabled, which will unconditionally
enforce FIPS compliance in any algorithm usage.

Thus there is no need to keep either the -enable-fips option in QEMU, or
QEMU's internal FIPS checking methods.

b25a948875 iotests: add findtests.py
Add python script with new logic of searching for tests:

Current ./check behavior:
 - tests are named [0-9][0-9][0-9]
 - tests must be registered in group file (even if test doesn't belong
   to any group, like 142)

Behavior of findtests.py:
 - group file is dropped
 - tests are all files in tests/ subdirectory (except for .out files),
   so it's not needed more to "register the test", just create it with
   appropriate name in tests/ subdirectory. Old names like
   [0-9][0-9][0-9] (in root iotests directory) are supported too, but
   not recommended for new tests
 - groups are parsed from '# group: ' line inside test files
 - optional file group.local may be used to define some additional
   groups for downstreams
 - 'disabled' group is used to temporary disable tests. So instead of
   commenting tests in old 'group' file you now can add them to
   disabled group with help of 'group.local' file
 - selecting test ranges like 5-15 are not supported more
   (to support restarting failed ./check command from the middle of the
    process, new argument is added: --start-from)

Benefits:
 - no rebase conflicts in group file on patch porting from branch to
   branch
 - no conflicts in upstream, when different series want to occupy same
   test number
 - meaningful names for test files
   For example, with digital number, when some person wants to add some
   test about block-stream, he most probably will just create a new
   test. But if there would be test-block-stream test already, he will
   at first look at it and may be just add a test-case into it.
   And anyway meaningful names are better.

This commit doesn't update check behavior (which will be done in
further commit), still, the documentation changed like new behavior is
already here.  Let's live with this small inconsistency for the
following few commits, until final change.

ccd3b3b811 qemu-option: warn for short-form boolean options
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.

cfb5387a1d hmp: remove "change vnc TARGET" command
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.

b93f4fbdc4 docs: Build and install all the docs in a single manual
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.

1e943c586a hw/misc: Add a PWM module for NPCM7XX
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.

77c05b0b74 hw/adc: Add an ADC module for NPCM7XX
The ADC is part of NPCM7XX Module. Its behavior is controled by the
ADC_CON register. It converts one of the eight analog inputs into a
digital input and stores it in the ADC_DATA register when enabled.

Users can alter input value by using qom-set QMP command.

554d523785 clock: Introduce clock_ticks_to_ns()
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.

The tracetool.py script writes to stdout. This means the output filename

This also simplifies the tracetool.py invocation. It's no longer

Merge remote-tracking branch 'remotes/maxreitz/tags/pull-block-2020-12-18' into staging

Block patches:
- New block filter: preallocate (which, on writes beyond an image file's
  end, allocates big chunks of data so that such post-EOF writes will
  occur less frequently)
- write-zeroes and block-status support for Quorum
- Implementation of truncate for the nvme block driver similarly to the
  existing implementations for host block devices and iscsi devices
- Block layer refactoring: Drop the tighten_restrictions concept in the
  block permission functions
- iotest fixes

54aa3de72e qapi: Use QAPI_LIST_PREPEND() where possible
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).

f518be3aa3 target/ppc: Remove "compat" property of server class POWER CPUs
This property has been deprecated since QEMU 5.0 by commit 22062e54bb.
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.

486966e4a4 scripts: kernel-doc: allow passing desired Sphinx C domain dialect
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.

c5d7cfdaac docs/system/virtio-pmem.rst: Fix minor style issues
The virtio-pmem documentation has some minor style issues we hadn't
noticed since we weren't rendering it in our docs:

 * Sphinx doesn't complain about overlong title-underlining the
   way it complains about too-short underlining, but it looks odd;
   make the underlines of section headers the right length

 * Indent of paragraphs makes them render as blockquotes;
   remove the indent so they just render as normal text

 * Leading 'o' isn't rst markup, so it just renders as a literal
   "o"; reformat as a subsection heading instead

 * "QEMU" in the document title and section headings are a bit
   odd and unnecessary since this is the QEMU manual; delete
   or rephrase them

 * There's no need to specify what QEMU version the device first
   appeared in.

Since commit aa35ec2213 ("hw/arm/raspi: Use more specific

as raspi2b/raspi3b.

Note, rather than the raspi3b, the raspi3ap introduced in
commit 5be94252d3 ("hw/arm/raspi: Add the Raspberry Pi 3
model A+") is a closer match to what QEMU models, but only
provides 512 MB of RAM.

As more Raspberry Pi 2/3 models are emulated, in order
to avoid confusion, deprecate the raspi2/raspi3 machine
aliases.

The man page does not contain all the chapters from the System Emulation

descriptions can not be resolved and thus the link names are used in the
man pages instead. These link names currently contain weird "_005f" letters
in the middle and just do not make any sense for the users. To avoid this
situation, replace the link names with more descriptive, natural text.

3009edff81 vhost-user: fix VHOST_USER_ADD/REM_MEM_REG truncation
QEMU currently truncates the mmap_offset field when sending
VHOST_USER_ADD_MEM_REG and VHOST_USER_REM_MEM_REG messages. The struct
layout looks like this:

  typedef struct VhostUserMemoryRegion {
      uint64_t guest_phys_addr;
      uint64_t memory_size;
      uint64_t userspace_addr;
      uint64_t mmap_offset;
  } VhostUserMemoryRegion;

  typedef struct VhostUserMemRegMsg {
      uint32_t padding;
      /* WARNING: there is a 32-bit hole here! */
      VhostUserMemoryRegion region;
  } VhostUserMemRegMsg;

The payload size is calculated as follows when sending the message in
hw/virtio/vhost-user.c:

  msg->hdr.size = sizeof(msg->payload.mem_reg.padding) +
      sizeof(VhostUserMemoryRegion);

This calculation produces an incorrect result of only 36 bytes.
sizeof(VhostUserMemRegMsg) is actually 40 bytes.

The consequence of this is that the final field, mmap_offset, is
truncated. This breaks x86_64 TCG guests on s390 hosts. Other guest/host
combinations may get lucky if either of the following holds:
1. The guest memory layout does not need mmap_offset != 0.
2. The host is little-endian and mmap_offset <= 0xffffffff so the
   truncation has no effect.

Fix this by extending the existing 32-bit padding field to 64-bit. Now
the padding reflects the actual compiler padding. This can be verified
using pahole(1).

Also document the layout properly in the vhost-user specification.  The
vhost-user spec did not document the exact layout. It would be
impossible to implement the spec without looking at the QEMU source
code.

Existing vhost-user frontends and device backends continue to work after
this fix has been applied. The only change in the wire protocol is that
QEMU now sets hdr.size to 40 instead of 36. If a vhost-user
implementation has a hardcoded size check for 36 bytes, then it will
fail with new QEMUs. Both QEMU and DPDK/SPDK don't check the exact
payload size, so they continue to work.

a60442eb8d target/mips: Deprecate nanoMIPS ISA
The nanoMIPS ISA has been announced in 2018 for various projects:

GCC:   https://gcc.gnu.org/legacy-ml/gcc/2018-05/msg00012.html
Linux: https://lwn.net/Articles/753605/
QEMU:  https://www.mail-archive.com/qemu-devel@nongnu.org/msg530721.html

Unfortunately the links referenced doesn't work anymore (www.mips.com).

From this Wayback machine link [1] we can get to a working place to
download a toolchain (a more recent release than the one referenced
in the announcement mails):
http://codescape.mips.com/components/toolchain/nanomips/2018.04-02/downloads.html

The toolchain page mention LLVM but simply links http://llvm.org/
where there is no reference on nanoMIPS.

The only reference in the GCC mailing list, is the nanoMIPS
announcement: https://gcc.gnu.org/pipermail/gcc/2018-May.txt

The developer who authored the announcements have been emailed [2]
to ask for more information but all their emails are now bouncing:

- Your message to Stefan.Markovic@mips.com couldn't be delivered.

- Your message to smarkovic@wavecomp.com couldn't be delivered.

- Couldn't deliver the message to the following recipients:
    Robert.Suchanek@mips.com, matthew.fortune@mips.com,
    marcin.nowakowski@mips.com

Our deprecation policy do not allow feature removal before 2 release,
therefore declare the nanoMIPS ISA code deprecated as of QEMU 5.2.
This gives time to developers to update the QEMU community, or
interested parties to step in to maintain this code.

f169413c27 hw/mips: Remove the 'r4k' machine
We deprecated the support for the 'r4k' machine for the 5.0 release
(commit d32dc61421), 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:
- this virtual machine has no specification
- the Linux kernel dropped support for it 10 years ago

Users are recommended to use the Malta board instead.

5a4b0d4112 qemu-option-trace.rst.inc: Don't use option:: markup
Sphinx 3.2 is pickier than earlier versions about the option:: markup,
and complains about our usage in qemu-option-trace.rst:

../../docs/qemu-option-trace.rst.inc:4:Malformed option description
  '[enable=]PATTERN', should look like "opt", "-opt args", "--opt args",
  "/opt args" or "+opt args"

In this file, we're really trying to document the different parts of
the top-level --trace option, which qemu-nbd.rst and qemu-img.rst
have already introduced with an option:: markup.  So it's not right
to use option:: here anyway.  Switch to a different markup
(definition lists) which gives about the same formatted output.

(Unlike option::, this markup doesn't produce index entries; but
at the moment we don't do anything much with indexes anyway, and
in any case I think it doesn't make much sense to have individual
index entries for the sub-parts of the --trace option.)

dbc7b01492 nbd: Add 'qemu-nbd -A' to expose allocation depth
Allow the server to expose an additional metacontext to be requested
by savvy clients.  qemu-nbd adds a new option -A to expose the
qemu:allocation-depth metacontext through NBD_CMD_BLOCK_STATUS; this
can also be set via QMP when using block-export-add.

qemu as client is hacked into viewing the key aspects of this new
context by abusing the already-experimental x-dirty-bitmap option to
collapse all depths greater than 2, which results in a tri-state value
visible in the output of 'qemu-img map --output=json' (yes, that means
x-dirty-bitmap is now a bit of a misnomer, but I didn't feel like
renaming it as it would introduce a needless break of back-compat,
even though we make no compat guarantees with x- members):

unallocated (depth 0) => "zero":false, "data":true
local (depth 1)       => "zero":false, "data":false
backing (depth 2+)    => "zero":true,  "data":true

libnbd as client is probably a nicer way to get at the information
without having to decipher such hacks in qemu as client. ;)

71719cd57f nbd: Add new qemu:allocation-depth metadata context
'qemu-img map' provides a way to determine which extents of an image
come from the top layer vs. inherited from a backing chain.  This is
useful information worth exposing over NBD.  There is a proposal to
add a QMP command block-dirty-bitmap-populate which can create a dirty
bitmap that reflects allocation information, at which point the
qemu:dirty-bitmap:NAME metadata context can expose that information
via the creation of a temporary bitmap, but we can shorten the effort
by adding a new qemu:allocation-depth metadata context that does the
same thing without an intermediate bitmap (this patch does not
eliminate the need for that proposal, as it will have other uses as
well).

While documenting things, remember that although the NBD protocol has
NBD_OPT_SET_META_CONTEXT, the rest of its documentation refers to
'metadata context', which is a more apt description of what is
actually being used by NBD_CMD_BLOCK_STATUS: the user is requesting
metadata by passing one or more context names.  So I also touched up
some existing wording to prefer the term 'metadata context' where it
makes sense.

Note that this patch does not actually enable any way to request a
server to enable this context; that will come in the next patch.

cbad81cef8 nbd: Update qapi to support exporting multiple bitmaps
Since 'block-export-add' is new to 5.2, we can still tweak the
interface; there, allowing 'bitmaps':['str'] is nicer than
'bitmap':'str'.  This wires up the qapi and qemu-nbd changes to permit
passing multiple bitmaps as distinct metadata contexts that the NBD
client may request, but the actual support for more than one will
require a further patch to the server.

Note that there are no changes made to the existing deprecated
'nbd-server-add' command; this required splitting the QAPI type
BlockExportOptionsNbd, which fortunately does not affect QMP
introspection.

526dbbe087 hw/gpio: Add GPIO model for Nuvoton NPCM7xx
The NPCM7xx chips have multiple GPIO controllers that are mostly
identical except for some minor differences like the reset values of
some registers. Each controller controls up to 32 pins.

Each individual pin is modeled as a pair of unnamed GPIOs -- one for
emitting the actual pin state, and one for driving the pin externally.
Like the nRF51 GPIO controller, a gpio level may be negative, which
means the pin is not driven, or floating.

e23e7b1259 hw/arm/npcm7xx: Add EHCI and OHCI controllers
The NPCM730 and NPCM750 chips have a single USB host port shared between
a USB 2.0 EHCI host controller and a USB 1.1 OHCI host controller. This
adds support for both of them.

Testing notes:
  * With -device usb-kbd, qemu will automatically insert a full-speed
    hub, and the keyboard becomes controlled by the OHCI controller.
  * With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly
    attached to the port without any hubs, and the device becomes
    controlled by the EHCI controller since it's high speed capable.
  * With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the
    keyboard is directly attached to the port, but it only advertises
    itself as full-speed capable, so it becomes controlled by the OHCI
    controller.

In all cases, the keyboard device enumerates correctly.

The RNG module returns a byte of randomness when the Data Valid bit is

This implementation ignores the prescaler setting, and loads a new value
into RNGD every time RNGCS is read while the RNG is enabled and random
data is available.

A qtest featuring some simple randomness tests is included.

1d84a0213a tools/virtiofsd: xattr name mappings: Simple 'map'
The mapping rule system implemented in the last few patches is
extremely flexible, but not easy to use.  Add a simple
'map' type as a sprinkling of sugar to make it easy.

e.g.

  -o xattrmap=":map::user.virtiofs.:"

would be sufficient to prefix all xattr's
or

  -o xattrmap=":map:trusted.:user.virtiofs.:"

would just prefix 'trusted.' xattr's and leave
everything else alone.

6084633dff tools/virtiofsd: xattr name mappings: Add option
Add an option to define mappings of xattr names so that
the client and server filesystems see different views.
This can be used to have different SELinux mappings as
seen by the guest, to run the virtiofsd with less privileges
(e.g. in a case where it can't set trusted/system/security
xattrs but you want the guest to be able to), or to isolate
multiple users of the same name; e.g. trusted attributes
used by stacking overlayfs.

A mapping engine is used with 3 simple rules; the rules can
be combined to allow most useful mapping scenarios.
The ruleset is defined by -o xattrmap='rules...'.

This patch doesn't use the rule maps yet.

06844584b6 virtiofsd: add container-friendly -o sandbox=chroot option
virtiofsd cannot run in a container because CAP_SYS_ADMIN is required to
create namespaces.

Introduce a weaker sandbox mode that is sufficient in container
environments because the container runtime already sets up namespaces.
Use chroot to restrict path traversal to the shared directory.

virtiofsd loses the following:

1. Mount namespace. The process chroots to the shared directory but
   leaves the mounts in place. Seccomp rejects mount(2)/umount(2)
   syscalls.

2. Pid namespace. This should be fine because virtiofsd is the only
   process running in the container.

3. Network namespace. This should be fine because seccomp already
   rejects the connect(2) syscall, but an additional layer of security
   is lost. Container runtime-specific network security policies can be
   used drop network traffic (except for the vhost-user UNIX domain
   socket).

not make sense anymore since KVM is available on other architectures,
too), it does not do anything by default in upstream QEMU (since TCG
is the default here anyway), and we're spending too much precious time
each year discussing whether it makes sense to keep this option as a
nice suger or not... let's finally put an end on this and remove it.

09e93326e4 build: replace ninjatool with ninja
Now that the build is done entirely by Meson, there is no need
to keep the Makefile conversion.  Instead, we can ask Ninja about
the targets it exposes and forward them.

The main advantages are, from smallest to largest:

- reducing the possible namespace pollution within the Makefile

- removal of a relatively large Python program

- faster build because parsing Makefile.ninja is slower than
parsing build.ninja; and faster build after Meson runs because
we do not have to generate Makefile.ninja.

- tracking of command lines, which provides more accurate rebuilds

In addition the change removes the requirement for GNU make 3.82, which
was annoying on Mac, and avoids bugs on Windows due to ninjatool not
knowing how to convert Windows escapes to POSIX escapes.

e1c4269763 block: deprecate the sheepdog block driver
This thread from a little over a year ago:

  http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html

states that sheepdog is no longer actively developed. The only mentioned
users are some companies who are said to have it for legacy reasons with
plans to replace it by Ceph. There is talk about cutting out existing
features to turn it into a simple demo of how to write a distributed
block service. There is no evidence of anyone working on that idea:

  https://github.com/sheepdog/sheepdog/commits/master

No real commits to git since Jan 2018, and before then just some minor
technical debt cleanup.

There is essentially no activity on the mailing list aside from
patches to QEMU that get CC'd due to our MAINTAINERS entry.

Fedora packages for sheepdog failed to build from upstream source
because of the more strict linker that no longer merges duplicate
global symbols. Fedora patches it to add the missing "extern"
annotations and presumably other distros do to, but upstream source
remains broken.

There is only basic compile testing, no functional testing of the
driver.

Since there are no build pre-requisites the sheepdog driver is currently
enabled unconditionally. This would result in configure issuing a
deprecation warning by default for all users. Thus the configure default
is changed to disable it, requiring users to pass --enable-sheepdog to
build the driver.

4258c8e221 docs/system/deprecated: Mark the 'moxie' CPU as deprecated
It is currently unclear whether anybody is still using the 'moxie' CPU,
and there are no images for testing available this CPU, so the code has
likely bit-rotten in the course of time. When I asked the maintainer
for information, I did not get a reply within four weeks yet (see
https://lists.gnu.org/archive/html/qemu-devel/2020-08/msg07201.html).
The last Signed-off-by line from Anthony in our repo is from 2013,
so it seems like this code is rather unmaintained. Time to put it onto
the deprecation list to see whether somebody is still interested in this
code or whether we could remove it in a couple of releases.

f6698f2b03 tools/virtiofsd: add support for --socket-group
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.

bb4b9ead95 hmp: Add support for coroutine command handlers
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.

04f22362f1 qapi: Add a 'coroutine' flag for commands
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.

aaaa20b69b scripts: add block-coroutine-wrapper.py
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.

55ec69f8b1 docs/devel/qapi-code-gen.txt: Update to new rST backend conventions
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

b3f4830ab3 meson.build: Make manuals depend on source to Sphinx extensions
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.

4ac2ee194b docs/interop: Convert qemu-qmp-ref to rST
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.

4078ee5469 docs/sphinx: Add new qapi-doc Sphinx extension
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.

a69a6d4b4d scripts/qapi/parser.py: improve doc comment indent handling
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.

  ../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.

ef1f5b0a96 docs/system: clarify deprecation schedule
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
25956af3fe ("block: Finish deprecation of
'qemu-img convert -n -o'"). The feature was deprecated in QEMU 4.2.0. It
was present in the 5.0.0 release and removed in the 5.1.0 release.

f701c082e7 i386/kvm: correct the meaning of '0xffffffff' value for hv-spinlocks
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. In TLFS version 6.0 the mistake was
corrected to 'never notify' which sounds logical. Fix QEMU accordingly.

353a06b425 manual: escape backslashes in "parsed-literal" blocks
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.

d849800512 Deprecate lm32 port
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 4b4d96c776 (March 2020) we marked it as 'orphan' in
the MAINTAINERS file, but didn't officially deprecate it. Mark it
deprecated now, with the intention of removing it from QEMU in
mid-2021 before the 6.1 release.

82bf7ae84c target/arm: Remove KVM support for 32-bit Arm hosts
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.

move the more involved plugins into contrib. tests/plugins still exist

221db5daf6 qapi: enable use of g_autoptr with QAPI types
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.

1a94933fcc meson: use pkg-config method to find dependencies
We do not need to ask cmake for the dependencies, so just use the
pkg-config mechanism.  Keep "auto" for SDL so that it tries using
sdl-config too.

The documentation is adjusted to use SDL2_image as the example,
rather than SDL which does not use the "pkg-config" method.

491e74c158 meson: pass docdir option
When cross-compiling, by default qemu_docdir is 'c:\Program Files\QEMU\'
which is not recognized as being an absolute path, and meson will end up
adding the prefix again.

Add an option to pass docdir location to meson, pre-prefixed like we do
with other directories, build qemu_docdir with the common suffix and use
that instead of config_host['qemu_docdir'].

d7c1523f58 hw/usb: Add U2F device autoscan to passthru mode
This patch adds an autoscan to let u2f-passthru choose the first U2F
device it finds.

The autoscan is performed using libudev with an enumeration of all the
hidraw devices present on the host.

The first device which happens to be a U2F device is taken to do the
passtru.

88fc107956 virtiofsd: Disable remote posix locks by default
Right now we enable remote posix locks by default. That means when guest
does a posix lock it sends request to server (virtiofsd). But currently
we only support non-blocking posix lock and return -EOPNOTSUPP for
blocking version.

This means that existing applications which are doing blocking posix
locks get -EOPNOTSUPP and fail. To avoid this, people have been
running virtiosd with option "-o no_posix_lock". For new users it
is still a surprise and trial and error takes them to this option.

Given posix lock implementation is not complete in virtiofsd, disable
it by default. This means that posix locks will work with-in applications
in a guest but not across guests. Anyway we don't support sharing
filesystem among different guests yet in virtiofs so this should
not lead to any kind of surprise or regression and will make life
little easier for virtiofs users.

f8aa24ea9a meson: sphinx-build
For now, sphinx is run on every invocation of make.  The previous mechanism
using $(wildcard) is not reproducible in Meson and was also brittle; for
example some .rst.inc files were left out.  The next patch will introduce

a81df1b68b libqemuutil, qapi, trace: convert to meson
This shows how to do some "computations" in meson.build using its array
and dictionary data structures, and also a basic usage of the sourceset
module for conditional compilation.

Notice the new "if have_system" part of util/meson.build, which fixes
a bug in the old build system was buggy: util/dbus.c was built even for
non-softmmu builds, but the dependency on -lgio was lost when the linking
was done through libqemuutil.a.  Because all of its users required gio
otherwise, the bug was hidden.  Meson instead propagates libqemuutil's
dependencies down to its users, and shows the problem.

c55bcb1f47 spapr: Clarify error and documentation for broken KVM XICS
When starting an L2 KVM guest with `ic-mode=dual,kernel-irqchip=on`,
QEMU fails with:

KVM is too old to support ic-mode=dual,kernel-irqchip=on

This error message was introduced to detect older KVM versions that
didn't allow destruction and re-creation of the XICS KVM device that
we do at reboot. But it is actually the same issue that we get with
nested guests : when running under pseries, KVM currently provides
a genuine XICS device (not the XICS-on-XIVE device that we get
under powernv) which doesn't support destruction/re-creation.

This will eventually be fixed in KVM but in the meantime, update
the error message and documentation to mention the nested case.
While here, mention that in "No XIVE support in KVM" section that
this can also happen with "guest OSes supporting XIVE" since
we check this at init time before starting the guest.

61f5e1a34d docs: adding NUMA documentation for pseries
This patch adds a new documentation file, ppc-spapr-numa.rst,
informing what developers and user can expect of the NUMA distance
support for the pseries machine, up to QEMU 5.1.

In the (hopefully soon) future, when we rework the NUMA mechanics
of the pseries machine to at least attempt to contemplate user
choice, this doc will be extended to inform about the new
support.

f7160f3218 schemas: Add vim modeline
The various schemas included in QEMU use a JSON-based format which
is, however, strictly speaking not valid JSON.

As a consequence, when vim tries to apply syntax highlight rules
for JSON (as guessed from the file name), the result is an unreadable
mess which mostly consist of red markers pointing out supposed errors
in, well, pretty much everything.

Using Python syntax highlighting produces much better results, and
in fact these files already start with specially-formatted comments
that instruct Emacs to process them as if they were Python files.

This commit adds the equivalent special comments for vim.

3a9163af4e Fix CVE-2020-13253
By using invalidated address, guest can do out-of-bounds accesses.
 These patches fix the issue by only allowing SD card image sizes
 power of 2, and not switching to SEND_DATA state when the address
 is invalid (out of range).
 
 This issue was found using QEMU fuzzing mode (using --enable-fuzzing,
 see docs/devel/fuzzing.txt) and reported by Alexander Bulekov.

d9f059aa6c qemu-img: Deprecate use of -b without -F
Creating an image that requires format probing of the backing image is
potentially unsafe (we've had several CVEs over the years based on
probes leaking information to the guest on a subsequent boot, although
these days tools like libvirt are aware of the issue enough to prevent
the worst effects).  For example, if our probing algorithm ever
changes, or if other tools like libvirt determine a different probe
result than we do, then subsequent use of that backing file under a
different format will present corrupted data to the guest.
Fortunately, the worst effects occur only when the backing image is
originally raw, and we at least prevent commit into a probed raw
backing file that would change its probed type.

Still, it is worth starting a deprecation clock so that future
qemu-img can refuse to create backing chains that would rely on
probing, to encourage clients to avoid unsafe practices.  Most
warnings are intentionally emitted from bdrv_img_create() in the block
layer, but qemu-img convert uses bdrv_create() which cannot emit its
own warning without causing spurious warnings on other code paths.  In
the end, all command-line image creation or backing file rewriting now
performs a check.

Furthermore, if we probe a backing file as non-raw, then it is safe to
explicitly record that result (rather than relying on future probes);
only where we probe a raw image do we care about further warnings to
the user when using such an image (for example, commits into a
probed-raw backing file are prevented), to help them improve their
tooling.  But whether or not we make the probe results explicit, we
still warn the user to remind them to upgrade their workflow to supply
-F always.

iotest 114 specifically wants to create an unsafe image for later
amendment rather than defaulting to our new default of recording a
probed format, so it needs an update.  While touching it, expand it to
cover all of the various warnings enabled by this patch.  iotest 301
also shows a change to qcow messages.

bc5ee6da71 qcow2: Deprecate use of qemu-img amend to change backing file
The use of 'qemu-img amend' to change qcow2 backing files is not
tested very well.  In particular, our implementation has a bug where
if a new backing file is provided without a format, then the prior
format is blindly reused, even if this results in data corruption, but
this is not caught by iotests.

There are also situations where amending other options needs access to
the original backing file (for example, on a downgrade to a v2 image,
knowing whether a v3 zero cluster must be allocated or may be left
unallocated depends on knowing whether the backing file already reads
as zero), but the command line does not have a nice way to tell us
both the backing file to use for opening the image as well as the
backing file to install after the operation is complete.

Even if we do allow changing the backing file, it is redundant with
the existing ability to change backing files via 'qemu-img rebase -u'.
It is time to deprecate this support (leaving the existing behavior
intact, even if it is buggy), and at a point in the future, require
the use of only 'qemu-img rebase' for adjusting backing chain
relations, saving 'qemu-img amend' for changes unrelated to the
backing chain.

add8200dd1 block: Error if backing file fails during creation without -u
Back in commit 6e6e55f5 (Jul 2017, v2.10), we tweaked the code to warn
if the backing file could not be opened but the user gave a size,
unless the user also passes the -u option to bypass the open of the
backing file.  As one common reason for failure to open the backing
file is when there is mismatch in the requested backing format in
relation to what the backing file actually contains, we actually want
to open the backing file and ensure that it has the right format in as
many cases as possible.  iotest 301 for qcow demonstrates how
detecting explicit format mismatch is useful to prevent the creation
of an image that would probe differently than the user requested.  Now
is the time to finally turn the warning an error, as promised.

Note that the original warning was added prior to our documentation of
an official deprecation policy (eb22aeca, also Jul 2017), and because
the warning didn't mention the word "deprecated", we never actually
remembered to document it as such.  But the warning has been around
long enough that I don't see prolonging it another two releases.

      the tests passing for qcow v1, and to skip LUKS tests (including
      qcow2 LUKS) when the built qemu does not support it)
 - Refactoring in the block layer: Drop the basically unnecessary

   cluster size
 - Fix in block-copy code

108a64818e vhost-vdpa: introduce vhost-vdpa backend
Currently we have 2 types of vhost backends in QEMU: vhost kernel and
vhost-user. The above patch provides a generic device for vDPA purpose,
this vDPA device exposes to user space a non-vendor-specific configuration
interface for setting up a vhost HW accelerator, this patch set introduces
a third vhost backend called vhost-vdpa based on the vDPA interface.

Vhost-vdpa usage:

qemu-system-x86_64 -cpu host -enable-kvm \
    ......
    -netdev type=vhost-vdpa,vhostdev=/dev/vhost-vdpa-id,id=vhost-vdpa0 \
    -device virtio-net-pci,netdev=vhost-vdpa0,page-per-vq=on \
