The PIO Setup FIS is written in the PIO:Entry state, which comes before
the ATA and ATAPI data transfer states. As a result, the PIO Setup FIS
interrupt is now raised before DMA ends for ATAPI commands, and tests have
to be adjusted.
This is also hinted by the description of the command header in the AHCI
specification, where the "A" bit is described as
When ‘1’, indicates that a PIO setup FIS shall be sent by the device
indicating a transfer for the ATAPI command.
and also by the description of the ACMD (ATAPI command region):
The ATAPI command must be either 12 or 16 bytes in length. The length
transmitted by the HBA is determined by the PIO setup FIS that is sent
by the device requesting the ATAPI command.
QEMU, which conflates the "generator" and the "receiver" of the FIS into
one device, always uses ATAPI_PACKET_SIZE, aka 12, for the length.

It's not always 512, and it does wind up mattering for PIO tranfers,
because this means DRQ blocks are four times as big for ATAPI.
Replace an instance of 2048 with the correct define, too.
This patch by itself winds changing no behavior. fis->count is ignored
for CMD_PACKET, and sect_count only gets used in non-ATAPI cases.

than the network loader and expects some magic bytes in the header
of the file (see linux_s390_magic in pc-bios/s390-ccw/bootmap.c), so
we've got to add them in our boot code here, too.

Commit d759c951f3 ("replay: push
replay_mutex_lock up the call tree") removed the !timeout lock
optimization in the main loop.
The idea of the optimization was to avoid ping-pongs between threads by
keeping the Big QEMU Lock held across non-blocking (!timeout) main loop
iterations.
A warning is printed when the main loop spins without releasing BQL for
long periods of time. These warnings were supposed to aid debugging but
in practice they just alarm users. They are considered noise because
the cause of spinning is not shown and is hard to find.
Now that the lock optimization has been removed, there is no danger of
hogging the BQL. Drop the spin counter and the infamous warning.

New option will be used to allow commands, which are prepared/need
to run, during preconfig state. Other commands that should be able
to run in preconfig state, should be amended to not expect machine
in initialized state or deal with it.
For compatibility reasons, commands that don't use new flag
'allow-preconfig' explicitly are not permitted to run in
preconfig state but allowed in all other states like they used
to be.
Within this patch allow following commands in preconfig state:
qmp_capabilities
query-qmp-schema
query-commands
query-command-line-options
query-status
exit-preconfig
to allow qmp connection, basic introspection and moving to the next

This changes the x-blockdev-create QMP command so that it doesn't block
the monitor and the main loop any more, but starts a background job that
performs the image creation.
The basic job as implemented here is all that is necessary to make image
creation asynchronous and to provide a QMP interface that can be marked
stable, but it still lacks a few features that jobs usually provide: The
job will ignore pause commands and it doesn't publish more than very
basic progress yet (total-progress is 1 and current-progress advances
from 0 to 1 when the driver callbacks returns). These features can be
added later without breaking compatibility.

for failed jobs. Not surprisingly, this tends to result in completely
useless messages.
This adds a Job.error field that can contain an error string for a
failing job, and a parameter to job_completed() that sets the field. As
a default, if NULL is passed, we continue to use strerror(job->ret).
All existing callers are changed to pass NULL. They can be improved in
separate patches.

Add a test program for testing the CRB with the external swtpm.
The 1st test case extends a PCR and reads back the value and compares
it against an expected return packet.
The 2nd test case repeats the 1st test case and then migrates the
external swtpm's state along with the VM state to a destination
QEMU and swtpm and checks that the PCR has the expected value now.
The test cases require 'swtpm' to be installed on the system and
in the PATH and 'swtpm' must support the --tpm2 option. If this is
not the case, the test will be skipped.

Instead of having a 'bool ready' in BlockJob, add a function that
derives its value from the job status.
At the same time, this fixes the behaviour to match what the QAPI
documentation promises for query-block-job: 'true if the job may be
completed'. When the ready flag was introduced in commit ef6dbf1e46,
the flag never had to be reset to match the description because after
being ready, the jobs would immediately complete and disappear.
Job transactions and manual job finalisation were introduced only later.
With these changes, jobs may stay around even after having completed
(and they are not ready to be completed a second time), however their
patches forgot to reset the ready flag.

Currently the timer is cancelled and the block job is entered by

This patch leaves the job asleep when block_job_resume() is called.
Jobs can still be forcibly woken up using block_job_enter(), which is
used to cancel jobs.
After this patch drain no longer runs extra blockjob iterations. This

Commit 8565c3ab53 ("qemu-iotests: fix
185") identified a race condition in a sub-test.
Similar issues also affect the other sub-tests. If disk I/O completes
quickly, it races with the QMP 'quit' command. This causes spurious
test failures because QMP events are emitted in an unpredictable order.
This test relies on QEMU internals and there is no QMP API for getting
deterministic behavior needed to make this test 100% reliable. At the
same time, the test is useful and it would be a shame to remove it.
Add sleep 0.5 to reduce the chance of races. This is not a real fix but
appears to reduce spurious failures in practice.

COR across nodes (that is, you have some filter node between the
actually COR target and the node that performs the COR) cannot reliably
work together with the permission system when there is no explicit COR
node that can request the WRITE_UNCHANGED permission for its child.
This is because COR (currently) sneaks its requests by the usual
permission checks, so it can work without a WRITE* permission; but if
there is a filter node in between, that will re-issue the request, which
then passes through the usual check -- and if nobody has requested a
WRITE_UNCHANGED permission, that check will fail.
There is no real direct fix apart from hoping that there is someone who
has requested that permission; in case of just the qemu-io HMP command
(and no guest device), however, that is not the case. The real real fix
is to implement the copy-on-read flag through an implicitly added COR
node. Such a node can request the necessary permissions as shown in
this test.

Currently, common.qemu only allows to match for results indicating
success. The only way to fail is by provoking a timeout. However,
sometimes we do have a defined failure output and can match for that,
which saves us from having to wait for the timeout in case of failure.
Because failure can sometimes just result in a _notrun in the test, it
is actually important to care about being able to fail quickly.
Also, sometimes we simply do not get any specific output in case of
success. The only way to handle this currently would be to define an
error message as the string to look for, which means that actual success
results in a timeout. This is really bad because it unnecessarily slows
down a succeeding test.
Therefore, this patch adds a new parameter $success_or_failure to
_timed_wait_for and _send_qemu_cmd. Setting this to a non-empty string
makes both commands expect two match parameters: If the first matches,
the function succeeds. If the second matches, the function fails.

The L2 and refcount caches have default sizes that can be overridden
using the l2-cache-size and refcount-cache-size (an additional
parameter named cache-size sets the combined size of both caches).
Unless forced by one of the aforementioned parameters, QEMU will set
the unspecified sizes so that the L2 cache is 4 times larger than the
refcount cache.
This is based on the premise that the refcount metadata needs to be
only a fourth of the L2 metadata to cover the same amount of disk
space. This is incorrect for two reasons:
a) The amount of disk covered by an L2 table depends solely on the
cluster size, but in the case of a refcount block it depends on
the cluster size *and* the width of each refcount entry.
The 4/1 ratio is only valid with 16-bit entries (the default).
b) When we talk about disk space and L2 tables we are talking about
guest space (L2 tables map guest clusters to host clusters),
whereas refcount blocks are used for host clusters (including
L1/L2 tables and the refcount blocks themselves). On a fully
populated (and uncompressed) qcow2 file, image size > virtual size
so there are more refcount entries than L2 entries.
Problem (a) could be fixed by adjusting the algorithm to take into
account the refcount entry width. Problem (b) could be fixed by
increasing a bit the refcount cache size to account for the clusters
used for qcow2 metadata.
However this patch takes a completely different approach and instead
of keeping a ratio between both cache sizes it assigns as much as
possible to the L2 cache and the remainder to the refcount cache.
The reason is that L2 tables are used for every single I/O request
from the guest and the effect of increasing the cache is significant
and clearly measurable. Refcount blocks are however only used for
cluster allocation and internal snapshots and in practice are accessed
sequentially in most cases, so the effect of increasing the cache is
negligible (even when doing random writes from the guest).
So, make the refcount cache as small as possible unless the user
explicitly asks for a larger one.

We already have an extensive mirror test (041) which does cover
cancelling a mirror job, especially after it has emitted the READY
event. However, it does not check what exact events are emitted after
block-job-cancel is executed. More importantly, it does not use
throttling to ensure that it covers the case of block-job-cancel before
READY.
It would be possible to add this case to 041, but considering it is
already our largest test file, it makes sense to create a new file for
these cases.

Commit b76e4458b1 ("block/mirror: change
the semantic of 'force' of block-job-cancel") accidentally removed the
ratelimit in the mirror job.
Reintroduce the ratelimit but keep the block-job-cancel force=true
behavior that was added in commit
b76e4458b1.
Note that block_job_sleep_ns() returns immediately when the job is
cancelled. Therefore it's safe to unconditionally call
block_job_sleep_ns() - a cancelled job does not sleep.
This commit fixes the non-deterministic qemu-iotests 185 output. The
test relies on the ratelimit to make the job sleep until the 'quit'
command is processed. Previously the job could complete before the
'quit' command was received since there was no ratelimit.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.
The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked(). Unlike
qobject_decref(), qobject_unref() doesn't accept void *.
Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

By moving the base fields to a QObjectBase_, QObject can be a type
which also has a 'base' field. This allows writing a generic QOBJECT()
macro that will work with any QObject type, including QObject
itself. The container_of() macro ensures that the object to cast has a
QObjectBase_ base field, giving some type safety guarantees. QObject
must have no members but QObjectBase_ base, or else QOBJECT() breaks.
QObjectBase_ is not a typedef and uses a trailing underscore to make
it obvious it is not for normal use and to avoid potential abuse.

The proper way to convert from (abstract) QObject to a (concrete)
subtype is qobject_to(). Look for offenders that type cast instead:
$ git-grep '(Q[A-Z][a-z]* \*)'
hmp.c: qmp_device_add((QDict *)qdict, NULL, &err);
include/qapi/qmp/qobject.h: return (QObject *)obj;
qobject/qobject.c:static void (*qdestroy[QTYPE__MAX])(QObject *) = {
tests/check-qdict.c: dst = (QDict *)qdict_crumple(src, &error_abort);
The first two cast away const, the third isn't a type cast. Fix the
fourth.

The consoles ("sclpconsole" and "sclplmconsole") can only be configured
with "-device" and "-chardev" so far. Other machines use the convenience
option "-serial" to configure the default consoles, even for virtual
consoles like spapr-vty on the pseries machine. So let's support this
option on s390x, too. This way we can easily enable the serial console
here again with "-nodefaults", for example:
qemu-system-s390x -no-shutdown -nographic -nodefaults -serial mon:stdio
... which is way shorter than typing:
qemu-system-s390x -no-shutdown -nographic -nodefaults \
-chardev stdio,id=c1,mux=on -device sclpconsole,chardev=c1 \
-mon chardev=c1
The -serial parameter can also be used if you only want to see the QEMU
monitor on stdio without using -nodefaults, but not the console output.
That's something that is pretty impossible with the current code today:
qemu-system-s390x -no-shutdown -nographic -serial none
While we're at it, this patch also maps the second -serial option to the
"sclplmconsole", so that there is now an easy way to configure this second
console on s390x, too, for example:
qemu-system-s390x -no-shutdown -nographic -serial null -serial mon:stdio
Additionally, the new code is also smaller than the old one and we have
less s390x-specific code in vl.c :-)
I've also checked that migration still works as expected by migrating
a guest with console output back and forth between a qemu-system-s390x
that has this patch and an instance without this patch.

Commit 4486e89c21 ("vl: introduce
vm_shutdown()") added a bdrv_drain_all() call. As a side-effect of the
drain operation the block job iterates one more time than before. The
185 output no longer matches and the test is failing now.
It may be possible to avoid the superfluous block job iteration, but
that type of patch is not suitable late in the QEMU 2.12 release cycle.
This patch simply updates the 185 output file. The new behavior is
correct, just not optimal, so make the test pass again.

L2 entries for compressed clusters have a field that indicates the
number of sectors used to store the data in the image.
That's however not the size of the compressed data itself, just the
number of sectors where that data is located. The actual data size is
usually not a multiple of the sector size, and therefore cannot be
represented with this field.
The way it works is that QEMU reads all the specified sectors and
starts decompressing the data until there's enough to recover the
original uncompressed cluster. If there are any bytes left that
haven't been decompressed they are simply ignored.
One consequence of this is that even if the size field is larger than
it needs to be QEMU can handle it just fine: it will read more data
from disk but it will ignore the extra bytes.
This test creates an image with two compressed clusters that use 5
sectors (2.5 KB) each, increases the size field to the maximum (8192
sectors, or 4 MB) and verifies that the data can be read without
problems.
This test is important because while the decompressed data takes
exactly one cluster, the maximum value allowed in the compressed size
field is twice the cluster size. So although QEMU won't produce images
with such large values we need to make sure that it can handle them.
Another effect of increasing the size field is that it can make
it include data from the following host cluster(s). In this case
'qemu-img check' will detect that the refcounts are not correct, and
we'll need to rebuild them.
Additionally, this patch also tests that decreasing the size corrupts
the image since the original data can no longer be recovered. In this
case QEMU returns an error when trying to read the compressed data,
but 'qemu-img check' doesn't see anything wrong if the refcounts are
consistent.
One possible task for the future is to make 'qemu-img check' verify
the sizes of the compressed clusters, by trying to decompress the data
and checking that the size stored in the L2 entry is correct.

The value of CCOUNT special register is calculated as time elapsed
since CCOUNT == 0 multiplied by the core frequency. In icount mode time
increment between consecutive instructions that don't involve time
warps is constant, but unless the result of multiplication of this
constant by the core frequency is a whole number the CCOUNT increment
between these instructions may not be constant. E.g. with icount=7 each
instruction takes 128ns, with core clock of 10MHz CCOUNT values for
consecutive instructions are:
502: (128 * 502 * 10000000) / 1000000000 = 642.56
503: (128 * 503 * 10000000) / 1000000000 = 643.84
504: (128 * 504 * 10000000) / 1000000000 = 645.12
I.e.the CCOUNT increments depend on the absolute time. This results in
varying CCOUNT differences for consecutive instructions in tests that
involve time warps and don't set CCOUNT explicitly.
Change frequency of the core used in tests so that clock cycle takes
exactly 64ns. Change icount power used in tests to 6, so that each
instruction takes exactly 1 clock cycle. With these changes CCOUNT
increments only depend on the number of executed instructions and that's
what timer tests expect, so they work correctly.

Before the chardev name fix, the following error may happen: "attempt
to add duplicate property 'chr-test' to object (type 'container')",
due to races.
Sadly, error_vprintf() uses g_test_message(), so you have to use
read the cryptic --debug-log to see it. Later, it would make sense to
use g_critical() instead, and catch errors with
g_test_expect_message() (in glib 2.34).

When we try to allocate new clusters we first look for available ones
starting from s->free_cluster_index and once we find them we increase
their reference counts. Before we get to call update_refcount() to do
this last step s->free_cluster_index is already pointing to the next
cluster after the ones we are trying to allocate.
During update_refcount() it may happen however that we also need to
allocate a new refcount block in order to store the refcounts of these
new clusters (and to complicate things further that may also require
us to grow the refcount table). After all this we don't know if the
clusters that we originally tried to allocate are still available, so
we return -EAGAIN to ask the caller to restart the search for free
clusters.
This is what can happen in a common scenario:
1) We want to allocate a new cluster and we see that cluster N is
free.
2) We try to increase N's refcount but all refcount blocks are full,
so we allocate a new one at N+1 (where s->free_cluster_index was
pointing at).
3) Once we're done we return -EAGAIN to look again for a free
cluster, but now s->free_cluster_index points at N+2, so that's
the one we allocate. Cluster N remains unallocated and we have a
hole in the qcow2 file.
This can be reproduced easily:
qemu-img create -f qcow2 -o cluster_size=512 hd.qcow2 1M
qemu-io -c 'write 0 124k' hd.qcow2
After this the image has 132608 bytes (256 clusters), and the refcount
block is full. If we write 512 more bytes it should allocate two new
clusters: the data cluster itself and a new refcount block.
qemu-io -c 'write 124k 512' hd.qcow2
However the image has now three new clusters (259 in total), and the
first one of them is empty (and unallocated):
dd if=hd.qcow2 bs=512c skip=256 count=1 | hexdump -C
If we write larger amounts of data in the last step instead of the 512
bytes used in this example we can create larger holes in the qcow2
file.
What this patch does is reset s->free_cluster_index to its previous
value when alloc_refcount_block() returns -EAGAIN. This way the caller
will try to allocate again the original clusters if they are still
free.
The output of iotest 026 also needs to be updated because now that
images have no holes some tests fail at a different point and the
number of leaked clusters is different.

Commit d4e5ec877 already fixed things to work around Python 3's
lame bug of having LC_ALL=C not be 8-bit clean, when parsing the
main QMP qapi files; but failed to do likewise in the tests
directory. As a result, running 'LC_ALL=C make check' fails on
escape-too-big and unicode-str when using python 3 with a nasty
stack trace instead of the intended graceful error message that
QAPI doesn't yet support 8-bit data (the two tests contain
Unicode é, when parsed in UTF-8; they represent something
different when parsed in a proper single-byte C locale, but that
doesn't matter to the error message printed out, provided that
brain-dead Python hasn't first choked on the input instead of
being 8-bit clean).
Ideally, we'd teach the qapi generator scripts to automatically
slurp things in using UTF-8 regardless of locale, and to honor
content that is not limited to 7 bit data rather than gracefully
erroring out; but until then, since our graceful error depends
on python parsing 8-bit data (even if nothing we generate uses
8-bit data), our quick fix is to use the right locale when
running these tests.

Here "oob" stands for "Out-Of-Band". When "allow-oob" is set, it means
the command allows out-of-band execution.
The "oob" idea is proposed by Markus Armbruster in following thread:
https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html
This new "allow-oob" boolean will be exposed by "query-qmp-schema" as
well for command entries, so that QMP clients can know which commands
can be used in out-of-band calls. For example the command "migrate"
originally looks like:
{"name": "migrate", "ret-type": "17", "meta-type": "command",
"arg-type": "86"}
And it'll be changed into:
{"name": "migrate", "ret-type": "17", "allow-oob": false,
"meta-type": "command", "arg-type": "86"}
This patch only provides the QMP interface level changes. It does not
contain the real out-of-band execution implementation yet.

There were no QMP capabilities defined. Define the first capability,

After this patch, we will allow QMP clients to enable QMP capabilities
when sending the first "qmp_capabilities" command. Originally we are
starting QMP session with no arguments like:
{ "execute": "qmp_capabilities" }
Now we can enable some QMP capabilities using (take OOB as example,
which is the only capability that we support):
{ "execute": "qmp_capabilities",
"arguments": { "enable": [ "oob" ] } }
When the "arguments" key is not provided, no capability is enabled.
For capability "oob", the monitor needs to be run on a dedicated IO
thread, otherwise the command will fail. For example, trying to enable
OOB on a MUXed typed QMP monitor will fail.
One thing to mention is that QMP capabilities are per-monitor, and also
when the connection is closed due to some reason, the capabilities will
be reset.
Also, touch up qmp-test.c to test the new bits.

CentOS 6 lacks a realpath binary on the base install, which makes
all iotests runs fail since the 2.11 release:
001 - output mismatch (see 001.out.bad)
./check: line 815: realpath: command not found
diff: missing operand after `/home/dummy/qemu/tests/qemu-iotests/001.out'
diff: Try `diff --help' for more information.
Many of the uses of 'realpath' in the check script were being
used on the output of 'type -p' - but that is already an
absolute file name. While a canonical name can often be
shorter (realpath gets rid of /../), it can also be longer (due
to symlink expansion); and we really don't care if the name is
canonical, merely that it was an executable file with an
absolute path. These were broken in commit cceaf1db.
The remaining use of realpath was to convert a possibly relative
filename into an absolute one before calling diff to make it
easier to copy-and-paste the filename for moving the .bad file
into place as the new reference file even when running iotests
out-of-tree (see commit 93e53fb6), but $PWD can achieve the same
purpose.

When doing drive mirror to a low speed shared storage, if there was heavy
BLK IO write workload in VM after the 'ready' event, drive mirror block job
can't be canceled immediately, it would keep running until the heavy BLK IO
workload stopped in the VM.
Libvirt depends on the current block-job-cancel semantics, which is that
when used without a flag after the 'ready' event, the command blocks
until data is in sync. However, these semantics are awkward in other
situations, for example, people may use drive mirror for realtime
backups while still wanting to use block live migration. Libvirt cannot
start a block live migration while another drive mirror is in progress,
but the user would rather abandon the backup attempt as broken and
proceed with the live migration than be stuck waiting for the current
drive mirror backup to finish.
The drive-mirror command already includes a 'force' flag, which libvirt
does not use, although it documented the flag as only being useful to
quit a job which is paused. However, since quitting a paused job has
the same effect as abandoning a backup in a non-paused job (namely, the
destination file is not in sync, and the command completes immediately),
we can just improve the documentation to make the force flag obviously
useful.

Which commands ("verbs") are appropriate for jobs in which state is
also somewhat burdensome to keep track of.
As of this commit, it looks rather useless, but begins to look more
interesting the more states we add to the STM table.
A recurring theme is that no verb will apply to an 'undefined' job.
Further, it's not presently possible to restrict the "pause" or "resume"
verbs any more than they are in this commit because of the asynchronous
nature of how jobs enter the PAUSED state; justifications for some
seemingly erroneous applications are given below.
=====
Verbs
=====
Cancel: Any state except undefined.
Pause: Any state except undefined;
'created': Requests that the job pauses as it starts.
'running': Normal usage. (PAUSED)
'paused': The job may be paused for internal reasons,
but the user may wish to force an indefinite
user-pause, so this is allowed.
'ready': Normal usage. (STANDBY)
'standby': Same logic as above.
Resume: Any state except undefined;
'created': Will lift a user's pause-on-start request.
'running': Will lift a pause request before it takes effect.
'paused': Normal usage.
'ready': Will lift a pause request before it takes effect.
'standby': Normal usage.
Set-speed: Any state except undefined, though ready may not be meaningful.
Complete: Only a 'ready' job may accept a complete request.
=======
Changes
=======
(1)
To facilitate "nice" error checking, all five major block-job verb
interfaces in blockjob.c now support an errp parameter:
- block_job_user_cancel is added as a new interface.
- block_job_user_pause gains an errp paramter
- block_job_user_resume gains an errp parameter
- block_job_set_speed already had an errp parameter.
- block_job_complete already had an errp parameter.
(2)
block-job-pause and block-job-resume will no longer no-op when trying
to pause an already paused job, or trying to resume a job that isn't
paused. These functions will now report that they did not perform the
action requested because it was not possible.
iotests have been adjusted to address this new behavior.
(3)
block-job-complete doesn't worry about checking !block_job_started,
because the permission table guards against this.
(4)
test-bdrv-drain's job implementation needs to announce that it is
'ready' now, in order to be completed.

We're about to add several new states, and booleans are becoming
unwieldly and difficult to reason about. It would help to have a
more explicit bookkeeping of the state of blockjobs. To this end,
add a new "status" field and add our existing states in a redundant
manner alongside the bools they are replacing:
UNDEFINED: Placeholder, default state. Not currently visible to QMP
unless changes occur in the future to allow creating jobs
without starting them via QMP.
CREATED: replaces !!job->co && paused && !busy
RUNNING: replaces effectively (!paused && busy)
PAUSED: Nearly redundant with info->paused, which shows pause_count.
This reports the actual status of the job, which almost always
matches the paused request status. It differs in that it is
strictly only true when the job has actually gone dormant.
READY: replaces job->ready.
STANDBY: Paused, but job->ready is true.
New state additions in coming commits will not be quite so redundant:
WAITING: Waiting on transaction. This job has finished all the work
it can until the transaction converges, fails, or is canceled.
PENDING: Pending authorization from user. This job has finished all the
work it can until the job or transaction is finalized via
block_job_finalize. This implies the transaction has converged
and left the WAITING phase.
ABORTING: Job has encountered an error condition and is in the process
of aborting.
CONCLUDED: Job has ceased all operations and has a return code available
for query and may be dismissed via block_job_dismiss.
NULL: Job has been dismissed and (should) be destroyed. Should never
be visible to QMP.
Some of these states appear somewhat superfluous, but it helps define the
expected flow of a job; so some of the states wind up being synchronous
empty transitions. Importantly, jobs can be in only one of these states
at any given time, which helps code and external users alike reason about
the current condition of a job unambiguously.

the same. This helps tighten assertions of the STM graph and removes some
conditionals that would have been needed in the coming commits adding a
more explicit job lifetime management API.

The "40p" machine is using the Open Hack'Ware BIOS, just like the "prep"
machine, so we can test it accordingly with the boot-serial tester, too.
While we're at it, also change the strings that we are using for the
"prep" machine, so that this test now also checks some CLI parameters.

there is no point to read fields here but not actually
checking them so drop it and read only header + dsdt/facs
addresses since it's needed later to fetch that tables.
With this cleanup we can get rid of AcpiFadtDescriptorRev3/
ACPI_FADT_COMMON_DEF which have no users left.

Test
- start two vms (vm_a, vm_b)
- in a
- do writes from set A
- do writes from set B
- fix bitmap sha256
- clear bitmap
- do writes from set A
- start migration
- than, in b
- wait vm start (postcopy should start)
- do writes from set B
- check bitmap sha256
The test should verify postcopy migration and then merging with delta
(changes in target, during postcopy process).
Reduce supported cache modes to only 'none', because with cache on time
from source.STOP to target.RESUME is unpredictable and we can fail with
timout while waiting for target.RESUME.

This test case adds an NBD server export and then invokes
blockdev-snapshot-sync, which changes the BlockDriverState node that the
NBD server's BlockBackend points to. This is an interesting scenario to
test and exercises the code path fixed by the previous commit.

Commit afe35cde6 added additional actions to test 33, but forgot
to reset the image between tests. As a result, './check -nbd 33'
fails because the qemu-nbd process from the first half is still
occupying the port, preventing the second half from starting a
new qemu-nbd process. Worse, the failure leaves a rogue qemu-nbd
process behind even after the test fails, which causes knock-on
failures to later tests that also want to start qemu-nbd.
