c0af9e1fc7 qga/qapi-schema: Fix member documentation markup
GuestDiskStatsInfo's member documentation is parsed as ordinary text
due to missing colons.  The generated documentation shows these
members as "Not documented".

The fix is obvious: add the missing colons.

f2de3b926c qapi: Fix unintended definition lists in documentation
rST parses something like

    first line
        second line

as a definition list item, where "first line" is the term being
defined by "second line".

This bites us in a couple of places.  Here's one:

    # @bps_max: total throughput limit during bursts,
    #                     in bytes (Since 1.7)

scripts/qapi/parser.py parses this into an "argument section" with
name "bps_max" and text

    total throughput limit during bursts,
	      in bytes (Since 1.7)

docs/sphinx/qapidoc.py duly passes the text to the rST parser, which
parses it as another definition list.  Comes out as nested
definitions: term "bps_max: int (optional)" defined as term "total
throughput limit during bursts," defined as "in bytes (Since 1.7)".

rST truly is the Perl of ASCII-based markups.

Fix by deleting the extra indentation.

c110102898 qapi: Fix bullet list markup in documentation
Peter Maydell's commit 100cc4fe0f explains:

    rST insists on a blank line before and after a bulleted list [...]
    Add some extra blank lines in the doc comments so they're
    acceptable rST input.

It missed one in qapi/trace.json.

Paolo Bonzini later added another instance in qapi/stats.json,
providing further, if unintended, evidence for his quip that rST is
the Perl of ASCII-based markups.

Both are parsed as ordinary paragraph, resulting in garbled output.

John Snow missed the need for a blank line when converting
docs/devel/qapi-code-gen.txt to rST.

Add the blank lines we need to get the bullet lists recognized as
such.

Kevin Wolf and Lukas Straub added two more, but indented.  Sphinx
recognizes them as (indented) bullet lists.  The indentation looks
slightly off.

Insert a blank line and delete the extra indentation.

Fixes: 100cc4fe0f (qapi: Add blank lines before bulleted lists)
Fixes: 467ef823d8 (qmp: add filtering of statistics by target vCPU)

2. users must specify memory for all NUMA nodes (see [2])

This commit also separates descriptions for `mem` and `memdev` into two
paragraphs. The old doc describes legacy `mem` option first, and it was
a bit confusing.

6ee3624236 tests/avocado/tuxrun_baselines.py: improve code coverage for ppc64
Commit c0c8687ef0 disabled the
boot_linux.py test-case due to which the code coverage for ppc
decreased by around 2%. As per the discussion on
https://lore.kernel.org/qemu-devel/87sfdpqcy4.fsf@linaro.org/ it
was mentioned that the baseline test for ppc64 could be modified
to make up this 2% code coverage. This patch attempts to achieve
this 2% code coverage by adding various device command line
arguments (to ./qemu-system-ppc64) in the tuxrun_baselines.py
test-case.

The code coverage report with boot_linux.py, without it and finally
with these tuxrun_baselines.py changes is as follows:

With boot_linux.py
------------------
  lines......: 13.8% (58006 of 420997 lines)

dd562bbfd7 tests/avocado/machine_aspeed: Fix the broken ast2[56]00_evb_sdk tests
test_arm_ast2500_evb_sdk and test_arm_ast2600_evb_sdk are currently
failing. The problem is that they are trying to look for the login
prompt that does not have a newline at the end - but the logic in
_console_interaction() only handles full lines. It used to work by
accident in the past since there were sometimes kernel (warning and
error) messages popping up that finally provided a newline character
in the output, but since the tests have been changed to run with the
"quiet" kernel parameter, this is not working anymore.

To make this work reliably, we must not look for the "login:" prompt,
but have to use some text ending with a newline instead. And in the
ast2600 test, switch to ssh instead of trying to log into the serial
console - this works much more reliable and also has the benefit of
excercising the network interface here a little bit, too.

df1f50c3c4 .gitlab-ci.d/cirrus: Drop the CI job for compiling with FreeBSD 12
FreeBSD 13.0 has been released in April 2021:

 https://www.freebsd.org/releases/13.0R/announce/

According to QEMU's support policy, we stop supporting the previous
major release two years after the the new major release has been
published. So we can stop testing FreeBSD 12 in our CI now.

c1654c3e37 qemu-options: finesse the recommendations around -blockdev
We are a bit premature in recommending -blockdev/-device as the best
way to configure block devices. It seems there are times the more
human friendly -drive still makes sense especially when -snapshot is
involved.

Improve the language to hopefully make things clearer.

8b869aa591 scripts/device-crash-test: Add a parameter to run with TCG only
We're currently facing the problem that the device-crash-test script
runs twice as long in the CI when a runner supports KVM - which sometimes
results in a timeout of the CI job. To get a more deterministic runtime
here, add an option to the script that allows to run it with TCG only.

4d3bd91b26 gitlab-ci: Avoid to re-run "configure" in the device-crash-test jobs
After "make check-venv" had been added to these jobs, they started
to re-run "configure" each time since our logic in the makefile
thinks that some files are out of date here. Avoid it with the same
trick that we are using in buildtest-template.yml already by disabling
the up-to-date check via NINJA=":".

ec5ffa0056 tests/requirements.txt: bump up avocado-framework version to 101.0
Avocado version 101.0 has a fix to re-compute the checksum
of an asset file if the algorithm used in the *-CHECKSUM
file isn't the same as the one being passed to it by the
avocado user (i.e. the avocado_qemu python module).
In the earlier avocado versions this fix wasn't there due
to which if the checksum wouldn't match the earlier
checksum (calculated by a different algorithm), the avocado
code would start downloading a fresh image from the internet
URL thus making the test-cases take longer to execute.

Bump up the avocado-framework version to 101.0.

a67cceb071 vmstate-static-checker: Recognize "num" field
Recognize this field for VMS_ARRAY typed vmsd fields, then we can do proper
size matching with previous patch.

Note that this is compatible with old -dump-vmstate output, because when
"num" is not there we'll still use the old "size" only.

12c81e5ae9 migration/vmstate-dump: Dump array size too as "num"
For VMS_ARRAY typed vmsd fields, also dump the number of entries in the
array in -vmstate-dump.

Without such information, vmstate static checker can report false negatives
of incompatible vmsd on VMS_ARRAY typed fields, when the src/dst do not
have the same type of array defined.  It's because in the checker we only
check against size of fields within a VMSD field.

One example: e1000e used to have a field defined as a boolean array with 5
entries, then removed it and replaced it with UNUSED (in 31e3f318c8):

-        VMSTATE_BOOL_ARRAY(core.eitr_intr_pending, E1000EState,
-                           E1000E_MSIX_VEC_NUM),
+        VMSTATE_UNUSED(E1000E_MSIX_VEC_NUM),

It's a legal replacement but vmstate static checker is not happy with it,
because it checks only against the "size" field between the two
fields (here one is BOOL_ARRAY, the other is UNUSED):

For BOOL_ARRAY:

      {
        "field": "core.eitr_intr_pending",
        "version_id": 0,
        "field_exists": false,
        "size": 1
      },

For UNUSED:

      {
        "field": "unused",
        "version_id": 0,
        "field_exists": false,
        "size": 5
      },

It's not the script to blame because there's just not enough information
dumped to show the total size of the entry for an array.  Add it.

Note that this will not break old vmstate checker because the field will
just be ignored.

b405dfff1e migration: Disable postcopy + multifd migration
Since the introduction of multifd, it's possible to perform a multifd
migration and finish it using postcopy.

A bug introduced by yank (fixed on cfc3bcf373) was previously preventing
a successful use of this migration scenario, and now thing should be
working on most scenarios.

But since there is not enough testing/support nor any reported users for
this scenario, we should disable this combination before it may cause any
problems for users.

a17dbc4b79 qapi: allow unions to contain further unions
This extends the QAPI schema validation to permit unions inside unions,
provided the checks for clashing fields pass.

1e148b545f qapi: Improve specificity of type/member descriptions
Error messages describe object members, enumeration values, features,
and variants like ROLE 'NAME', where ROLE is "member", "value",
"feature", or "branch", respectively.  When the member is defined in
another type, e.g. inherited from a base type, we add "of type
'TYPE'".  Example: test case struct-base-clash-deep reports a member
of type 'Sub' clashing with a member of its base type 'Base' as

    struct-base-clash-deep.json: In struct 'Sub':
    struct-base-clash-deep.json:10: member 'name' collides with member 'name' of type 'Base'

Members of implicitly defined types need special treatment.  We don't
want to add "of type 'TYPE'" for them, because their named are made up
and mean nothing to the user.  Instead, we describe members of an
implicitly defined base type as "base member 'NAME'", and command and
event parameters as "parameter 'NAME'".  Example: test case
union-bad-base reports member of a variant's type clashing with a
member of its implicitly defined base type as

    union-bad-base.json: In union 'TestUnion':
    union-bad-base.json:8: member 'string' of type 'TestTypeA' collides with base member 'string'

The next commit will permit unions as variant types.  "base member
'NAME' would then be ambigious: is it the union's base, or is it the
union's variant's base?  One of its test cases would report a clash
between two such bases as "base member 'type' collides with base
member 'type'".  Confusing.

Refine the special treatment: add "of TYPE" even for implicitly
defined types, but massage TYPE and ROLE so they make sense for the
user.

7ce54db230 qapi: support updating expected test output via make
It is possible to pass --update to tests/qapi-schema/test-qapi.py
to make it update the output files on error. This is inconvenient
to achieve though when test-qapi.py is run indirectly by make/meson.

Instead simply allow for an env variable to be set:

 $ QAPI_TEST_UPDATE= make check-qapi-schema

8c1e8fb2e7 block/monitor: Fix crash when executing HMP commit
hmp_commit() calls blk_is_available() from a non-coroutine context (and
in the main loop). blk_is_available() is a co_wrapper_mixed_bdrv_rdlock
function, and in the non-coroutine context it calls AIO_WAIT_WHILE(),
which crashes if the aio_context lock is not taken before.

5a5a9fdd15 vmdk: make vmdk_is_cid_valid a coroutine_fn
Functions that can do I/O are prime candidates for being coroutine_fns.  Make the
change for the one that is itself called only from coroutine_fns.  Unfortunately
vmdk does not use a coroutine_fn for the bulk of the open (like qcow2 does) so
vmdk_read_cid cannot have the same treatment.

a39bae4ecd qcow2: mark various functions as coroutine_fn and GRAPH_RDLOCK
Functions that can do I/O (including calling bdrv_is_allocated
and bdrv_block_status functions) are prime candidates for being
coroutine_fns.  Make the change for those that are themselves called
only from coroutine_fns.  Also annotate that they are called with the
graph rdlock taken, thus allowing them to call bdrv_co_*() functions
for I/O.
