51514a34b3 tests/qtest: Skip Aarch64 VMapple machine
First, the VMapple machine only works with the ARM 'host' CPU
type, which isn't accepted for QTest:

  $ qemu-system-aarch64 -M vmapple -accel qtest
  qemu-system-aarch64: The 'host' CPU type can only be used with KVM or HVF

Second, the QTest framework expects machines to be createable
without specifying optional arguments, however the VMapple
machine requires few of them:

  $ qemu-system-aarch64 -M vmapple -accel qtest
  qemu-system-aarch64: No firmware specified

  $ qemu-system-aarch64 -M vmapple -accel qtest -bios /dev/null
  qemu-system-aarch64: No AUX device. Please specify one as pflash drive.

Restrict this machine with QTest so we can at least run check-qtest,
otherwise we get:

  $ make check-qtest-aarch64
  qemu-system-aarch64: The 'host' CPU type can only be used with KVM or HVF
  Broken pipe
  ../tests/qtest/libqtest.c:199: kill_qemu() tried to terminate QEMU process but encountered exit status 1 (expected 0)

d1368344bc rust: Kconfig: Factor out whether HPET is Rust or C
Currently we require everywhere that wants to know if there
is an HPET device to check for "CONFIG_HPET || CONFIG_X_HPET_RUST".
Factor out whether the HPET device is Rust or C into a separate
Kconfig stanza, so that CONFIG_HPET means "there is an HPET",
and whether this has pulled in CONFIG_X_HPET_RUST or CONFIG_HPET_C
is something the rest of QEMU can ignore.

538e03d280 tests/qtest/migration: Add a cancel test
The qmp_migrate_cancel() command is poorly tested and code inspection
reveals that there might be concurrency issues with its usage. Add a
test that runs a migration and calls qmp_migrate_cancel() at specific
moments.

In order to make the test more deterministic, instead of calling
qmp_migrate_cancel() at random moments during migration, do it after
the migration status change events are seen.

The expected result is that qmp_migrate_cancel() on the source ends
migration on the source with the "cancelled" state and ends migration
on the destination with the "failed" state. The only exception is that
a failed migration should continue in the failed state.

Cancelling is not allowed during postcopy (no test is added for this
because it's a trivial check in the code).

407bc4bf90 qapi: Move include/qapi/qmp/ to include/qobject/
The general expectation is that header files should follow the same
file/path naming scheme as the corresponding source file. There are
various historical exceptions to this practice in QEMU, with one of
the most notable being the include/qapi/qmp/ directory. Most of the
headers there correspond to source files in qobject/.

This patch corrects most of that inconsistency by creating
include/qobject/ and moving the headers for qobject/ there.

This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h:
scripts/get_maintainer.pl now reports "QAPI" instead of "No
maintainers found".

bc2a1f1a45 tests/qtest/migration: Add --full option
Add a new command line option to allow selecting between running the
full set of tests or a smaller set of tests. The default will be to
run the small set (i.e. no comand line option provided) so we can
reduce the amount of tests run by default. Only hosts which support
KVM for the target architecture being tested will run the complete set
of tests.

Adjust the meson.build file to pass in the --full option when
appropriate.

(for now, set the option unconditionally until the next patch actually
creates the small set)

Use cases:

configure --target-list=aarch64-softmmu,ppc64-softmmu,s390x-softmmu,x86_64-softmmu

9c38fea83b tests/qtest/libqos: add DMA support for writing and reading fw_cfg files
At present, the libqos/fw_cfg.c library does not support the modern DMA
interface which is required to write to the fw_cfg files. It only uses the IO
interface. Implement read and write methods based on DMA. This will enable
developers to add tests that writes to the fw_cfg file(s). The structure of
the code is taken from edk2 fw_cfg implementation. It has been tested by
writing a qtest that writes to a fw_cfg file.

4881411136 migration: Always set DEVICE state
DEVICE state was introduced back in 2017:

https://lore.kernel.org/qemu-devel/20171020090556.18631-1-dgilbert@redhat.com/

Quote from Dave's cover letter, when the pre-switchover phase was enabled,
the state transition looks like this:

  The precopy flow is:
  active->pre-switchover->device->completed

  The postcopy flow is:
  active->pre-switchover->postcopy-active->completed

To supplement above, when the cap is not enabled:

  The precopy flow is:
  active->completed

  The postcopy flow is:
  active->postcopy-active->completed

It works for us, though we have some code just to special case these state
transitions, so the DEVICE state currently is special only to precopy, and
only conditionally.

I had a quick discussion with Libvirt developers, it turns out that this
may not be necessary. IOW, it seems okay we can have DEVICE state to be
generic, so that we don't have over-complicated state machines.  It not
only helps align all the migration state machine, help cleanup the code
path especially on pre-switchover handling (see the patch itself), another
side benefit is we can unconditionally have a specific state to mark the
switchover phase, which might be helpful for debugging too.

This patch makes the DEVICE state to be present always, marking that source
QEMU is switching over.  Then the state machine will be always as simple
as:

  active-> [pre-switchover->] -> device -> [postcopy-active->] -> complete

After the change, no matter whether pre-switchover or postcopy is enabled
or not, we always have DEVICE state showing the switchover phase.  When
pre-switchover enabled, we'll have an extra stage before that.  When
postcopy is enabled, we'll have an extra stage after that.

A few qtests need touch up in QEMU tree for this change:

  - A few iotest outputs (194, 203, 234, 262, 280)
  - Teach libqos's migrate() on "device" state

360b5d773b migration-test: cpr-transfer
Add a migration test for cpr-transfer mode.  Defer the connection to the
target monitor, else the test hangs because in cpr-transfer mode QEMU does
not listen for monitor connections until we send the migrate command to
source QEMU.

To test -incoming defer, send a migrate incoming command to the target,
after sending the migrate command to the source, as required by
cpr-transfer mode.

3dec966f27 tests/qtest/migration: Use out-of-band execution for migrate-recover
In real use cases, the migrate-recover command requires out-of-band
execution, because the thread processing normal commands is blocked by a
page fault in the guest memory. With this change, the tests will be
closer to real use cases and could help detect regressions and other
bugs in migration recovery.
