Since commit 80d7835749 (qemu-options: rewrite help for -smp options),
the preference of sockets/cores in -smp parsing is considered liable
to change, and actually we are going to change it in a coming commit.
So it'll be more stable to use detailed -smp CLIs in the testcases
that have strong dependency on the parsing results.
Currently, test_def_cpu_split use "-smp 8" and will get 8 CPU sockets
based on current parsing rule. But if we change to prefer cores over
sockets we will get one CPU socket with 8 cores, and this testcase
will not get expected numa set by default on x86_64 (Ok on aarch64).
So now explicitly use "-smp 8,sockets=8" to avoid affect from parsing
logic change.

pc_dynamic_cpu_cfg currently assumes/needs that there will be 2 CPU
sockets with "-smp 2". To avoid breaking the test because of parsing
logic change, now explicitly use "-smp 2,sockets=2".

We are generally moving to int64_t for both offset and bytes parameters
on all io paths.
Main motivation is realization of 64-bit write_zeroes operation for
fast zeroing large disk chunks, up to the whole disk.
We chose signed type, to be consistent with off_t (which is signed) and
with possibility for signed return type (where negative value means
error).
So, convert driver discard handlers bytes parameter to int64_t.
The only caller of all updated function is bdrv_co_pdiscard in
block/io.c. It is already prepared to work with 64bit requests, but
pass at most max(bs->bl.max_pdiscard, INT_MAX) to the driver.
Let's look at all updated functions:
blkdebug: all calculations are still OK, thanks to
bdrv_check_qiov_request().
both rule_check and bdrv_co_pdiscard are 64bit
blklogwrites: pass to blk_loc_writes_co_log which is 64bit
blkreplay, copy-on-read, filter-compress: pass to bdrv_co_pdiscard, OK
copy-before-write: pass to bdrv_co_pdiscard which is 64bit and to
cbw_do_copy_before_write which is 64bit
file-posix: one handler calls raw_account_discard() is 64bit and both
handlers calls raw_do_pdiscard(). Update raw_do_pdiscard, which pass
to RawPosixAIOData::aio_nbytes, which is 64bit (and calls
raw_account_discard())
gluster: somehow, third argument of glfs_discard_async is size_t.
Let's set max_pdiscard accordingly.
iscsi: iscsi_allocmap_set_invalid is 64bit,
!is_byte_request_lun_aligned is 64bit.
list.num is uint32_t. Let's clarify max_pdiscard and
pdiscard_alignment.
mirror_top: pass to bdrv_mirror_top_do_write() which is
64bit
nbd: protocol limitation. max_pdiscard is alredy set strict enough,
keep it as is for now.
nvme: buf.nlb is uint32_t and we do shift. So, add corresponding limits
to nvme_refresh_limits().
preallocate: pass to bdrv_co_pdiscard() which is 64bit.
rbd: pass to qemu_rbd_start_co() which is 64bit.
qcow2: calculations are still OK, thanks to bdrv_check_qiov_request(),
qcow2_cluster_discard() is 64bit.
raw-format: raw_adjust_offset() is 64bit, bdrv_co_pdiscard too.
throttle: pass to bdrv_co_pdiscard() which is 64bit and to
throttle_group_co_io_limits_intercept() which is 64bit as well.
test-block-iothread: bytes argument is unused
Great! Now all drivers are prepared to handle 64bit discard requests,
or else have explicit max_pdiscard limits.

So, convert driver write handlers parameters which are already 64bit to
signed type.
While being here, convert also flags parameter to be BdrvRequestFlags.
Now let's consider all callers. Simple
git grep '\->bdrv_\(aio\|co\)_pwritev\(_part\)\?'
shows that's there three callers of driver function:
bdrv_driver_pwritev() and bdrv_driver_pwritev_compressed() in
block/io.c, both pass int64_t, checked by bdrv_check_qiov_request() to
be non-negative.
qcow2_save_vmstate() does bdrv_check_qiov_request().
Still, the functions may be called directly, not only by drv->...
Let's check:
git grep '\.bdrv_\(aio\|co\)_pwritev\(_part\)\?\s*=' | \
awk '{print $4}' | sed 's/,//' | sed 's/&//' | sort | uniq | \
while read func; do git grep "$func(" | \
grep -v "$func(BlockDriverState"; done
shows several callers:
qcow2:
qcow2_co_truncate() write at most up to @offset, which is checked in
generic qcow2_co_truncate() by bdrv_check_request().
qcow2_co_pwritev_compressed_task() pass the request (or part of the
request) that already went through normal write path, so it should
be OK
qcow:
qcow_co_pwritev_compressed() pass int64_t, it's updated by this patch
quorum:
quorum_co_pwrite_zeroes() pass int64_t and int - OK
throttle:
throttle_co_pwritev_compressed() pass int64_t, it's updated by this
patch
vmdk:
vmdk_co_pwritev_compressed() pass int64_t, it's updated by this
patch

bdrv_check_qiov_request() to be non-negative.
qcow2_load_vmstate() does bdrv_check_qiov_request().
do_perform_cow_read() has uint64_t argument. And a lot of things in
qcow2 driver are uint64_t, so converting it is big job. But we must
not work with requests that don't satisfy bdrv_check_qiov_request(),
so let's just assert it here.
Still, the functions may be called directly, not only by drv->...

grep -v "$func(BlockDriverState"; done
The only one such caller:
QEMUIOVector qiov = QEMU_IOVEC_INIT_BUF(qiov, &data, 1);
...
ret = bdrv_replace_test_co_preadv(bs, 0, 1, &qiov, 0);
in tests/unit/test-bdrv-drain.c, and it's OK obviously.

machine_ppc.py contains tests for 3 different ppc based machine types. It
is listed in MAINTAINERS along with the PPC TCG cpu code. That's not
really accurate though, since it's really more about testing those machines
than the CPUs.
Therefore, split it up into separate files for the separate machine types,
and list those along with their machine types in MAINTAINERS.

Although it is possible to run a specific test using the avocado
command-line, a user may want to use a specific tag while running the
``make check-acceptance`` during the development or debugging.
This allows using the AVOCADO_TAGS environment variable where the user
takes total control of which tests should run based on the tags defined.
This also makes the check-acceptance command flexible to restrict tests
based on tags while running on CI.
e.g.:
AVOCADO_TAGS="foo bar baz" make check-acceptance

The avocado.Test class, used as the basis of the avocado_qemu.Test
class, performs a clean of temporary directories up as part of its own
tearDown() implementation.
But the avocado_qemu.Test class is currently missing the same clean
up, as it implemented its own tearDown() method without resorting to
the upper class behavior.
This brings avocado_qemu.Test behavior in sync with the standard
avocado.Test behavior and prevents temporary directories from
cluttering the test results directory (unless instructed to do so with
Avocado's "--keep-tmp" option).

This patch adds a test for record/replay, which boots Linux
image from the disk and interacts with the network.
The idea and code of this test is borrowed from boot_linux.py
This test includes only x86_64 platform. Other platforms and
machines will be added later after testing and improving
record/replay to completely support them.
Each test consists of the following phases:
- downloading the disk image
- recording the execution
- replaying the execution
Replay does not validates the output, but waits until QEMU
finishes the execution. This is reasonable, because
QEMU usually hangs when replay goes wrong.

Simple unions predate flat unions. Having both complicates the QAPI
schema language and the QAPI generator. We haven't been using simple
unions in new code for a long time, because they are less flexible and
somewhat awkward on the wire.
The previous commits eliminated simple union from the tree. Now drop
them from the QAPI schema language entirely, and update mentions of
"flat union" to just "union".

Drop tests that are specifically about simple unions:
* SugaredUnion in doc-good: flat unions are covered by @Object.
* union-branch-case and union-clash-branches: branch naming for flat
unions is enforced for the tag enum instead, which is covered by
enum-member-case and enum-clash-member.
* union-empty: empty flat unions are covered by flat-union-empty.
Rewrite the remainder to use flat unions: args-union, bad-base,
flat-union-base-union, union-branch-invalid-dict, union-unknown.
Except drop union-optional-branch. because converting this one is not
worth the trouble; we don't explicitly check names beginning with '*'
in other places, either.

Replace simple union __org.qemu_x-Union1 with flat union
__org.qemu_x-Union2, except drop it from __org.qemu_x-command, because
there it's only used to pull it into QMP. Now drop the unused
-Union1, and rename -Union2 to -Union.

To prepare for their removal, simple union UserDefListUnion has to go.
It is used to cover arrays. The next few commits will eliminate its
uses, and then it gets deleted. As a first step, provide struct
ArrayStruct for the tests to be rewritten.

To prepare for their removal, convert simple union SocketAddressLegacy
to an equivalent flat one, with existing enum SocketAddressType
replacing implicit enum type SocketAddressLegacyKind. Adds some
boilerplate to the schema, which is a bit ugly, but a lot easier to
maintain than the simple union feature.

I'm about to convert simple unions to flat unions, then drop simple
union support. The conversion involves making the implict enum types
explicit. To reduce churn, I'd like to name them exactly like the
implicit types they replace. However, these names are reserved for
the generator's use. They won't be once simple unions are gone. Stop
enforcing this naming rule now rather than then.

Although we have long supported 'qemu-img convert -o
backing_file=foo,backing_fmt=bar', the fact that we have a shortcut -B
for backing_file but none for backing_fmt has made it more likely that
users accidentally run into:
qemu-img: warning: Deprecated use of backing file without explicit backing format
when using -B instead of -o. For similarity with other qemu-img
commands, such as create and compare, add '-F $fmt' as the shorthand
for '-o backing_fmt=$fmt'. Update iotest 122 for coverage of both
spellings.

There is no conflict and no dependency if we have parallel writes to
different subclusters of one cluster when the cluster itself is already
allocated. So, relax extra dependency.
Measure performance:
First, prepare build/qemu-img-old and build/qemu-img-new images.
cd scripts/simplebench
./img_bench_templater.py
Paste the following to stdin of running script:
qemu_img=../../build/qemu-img-{old|new}
$qemu_img create -f qcow2 -o extended_l2=on /ssd/x.qcow2 1G
$qemu_img bench -c 100000 -d 8 [-s 2K|-s 2K -o 512|-s $((1024*2+512))] \
-w -t none -n /ssd/x.qcow2
The result:
All results are in seconds
------------------ --------- ---------
old new
-s 2K 6.7 ± 15% 6.2 ± 12%
-7%
-s 2K -o 512 13 ± 3% 11 ± 5%
-16%
-s $((1024*2+512)) 9.5 ± 4% 8.4
-12%
------------------ --------- ---------
So small writes are more independent now and that helps to keep deeper
io queue which improves performance.
271 iotest output becomes racy for three allocation in one cluster.
Second and third writes may finish in different order. Second and
third requests don't depend on each other any more. Still they both
depend on first request anyway. Filter out second and third write
offsets to cover both possible outputs.

We must not inactivate child when parent has write permissions on
it.
Calling .bdrv_inactivate() doesn't help: actually only qcow2 has this
handler and it is used to flush caches, not for permission
manipulations.
So, let's simply check cumulative parent permissions before
inactivating the node.
This commit fixes a crash when we do migration during backup: prior to
the commit nothing prevents all nodes inactivation at migration finish
and following backup write to the target crashes on assertion
"assert(!(bs->open_flags & BDRV_O_INACTIVE));" in
bdrv_co_write_req_prepare().
After the commit, we rely on the fact that copy-before-write filter
keeps write permission on target node to be able to write to it. So
inactivation fails and migration fails as expected.
Corresponding test now passes, so, enable it.
