23c02ace35 docs: generate qemu-storage-daemon-qmp-ref(7) man page
Although individual qemu-storage-daemon QMP commands are identical to
QEMU QMP commands, qemu-storage-daemon only supports a subset of QEMU's
QMP commands. Generate a manual page of just the commands supported by
qemu-storage-daemon so that users know exactly what is available in
qemu-storage-daemon.

Add an h1 heading in storage-daemon/qapi/qapi-schema.json so that
block-core.json is at the h2 heading level.

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.

Note, rather than the raspi3b, the raspi3ap introduced in
commit 5be94252d3 ("hw/arm/raspi: Add the Raspberry Pi 3

provides 512 MB of RAM.

As more Raspberry Pi 2/3 models are emulated, in order

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.

326ccfe240 hw/misc: Add npcm7xx random number generator
The RNG module returns a byte of randomness when the Data Valid bit is
set.

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.

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.

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.
