a060297822 test-bitmap: test set 1 bit case for bitmap_set
All current bitmap_set test cases set range across word, while the
handle of a range within one word is different from that.

Add case to set 1 bit as a represent for set range within one word.

dcb1578069 util/qemu-timer: refactor deadline calculation for external timers
icount-based record/replay uses qemu_clock_deadline_ns_all to measure
the period until vCPU may be interrupted.
This function takes in account the virtual timers, because they belong
to the virtual devices that may generate interrupt request or affect
the virtual machine state.
However, there are a subset of virtual timers, that are marked with
'external' flag. These do not change the virtual machine state and
only based on virtual clock. Calculating the deadling using the external
timers breaks the determinism, because they do not belong to the replayed
part of the virtual machine.
This patch fixes the deadline calculation for this case by adding
new parameter for skipping the external timers when it is needed.

f673174e3f tests: Fix uninitialized byte in test_visitor_in_fuzz
One byte in the local buffer stays uninitialized, at least with the
first iteration, because of the double decrement in the
test_visitor_in_fuzz(). This is what Valgrind does not like and not
critical for the test itself. So, reduce the number of the memory
issues reports.

6eed53f71b target/mips: tests/tcg: Fix target configurations for MSA tests
At this moment, the only MIPS CPUs that are emulated in QEMU and
support MSA extension are R5600 (mips32r5), and I6400/I6500 (mips64r6).
Therefore, mips32r5 and mips64r6 are the only ISAs that could support
MSA in QEMU. This means mips32r6 currently do not make much sense, and
mips32r5 support for MSA tests is needed, which is done by this patch.

9c46f4a06d iotests: Fix 141 when run with qed
69f47505ee has changed qcow2 in such a way that the commit job run in
test 141 (and 144[1]) returns before it emits the READY event.  However,
141 also runs with qed, where the order is still the other way around.
Just filter out the {"return": {}} so the test passes for qed again.

[1] 144 only runs with qcow2, so it is fine as it is.

cdf3bc934a mirror: Fix bdrv_has_zero_init() use
bdrv_has_zero_init() only has meaning for newly created images or image
areas.  If the mirror job itself did not create the image, it cannot
rely on bdrv_has_zero_init()'s result to carry any meaning.

This is the case for drive-mirror with mode=existing and always for
blockdev-mirror.

Note that we only have to zero-initialize the target with sync=full,
because other modes actually do not promise that the target will contain
the same data as the source after the job -- sync=top only promises to
copy anything allocated in the top layer, and sync=none will only copy
new I/O.  (Which is how mirror has always handled it.)

bdd95e4784 tests: Run the iotests during "make check" again
People often forget to run the iotests before submitting patches or pull
requests - this is likely due to the fact that we do not run the tests
during our mandatory "make check" tests yet. Now that we've got a proper
"auto" group of iotests that should be fine to run in every environment,
we can enable the iotests during "make check" again by running the "auto"
tests by default from the check-block.sh script.

Some cases still need to be checked first, though: iotests need bash and
GNU sed (otherwise they fail), and if gprof is enabled, it spoils the
output of some test cases causing them to fail. So if we detect that one
of the required programs is missing or that gprof is enabled, we still
have to skip the iotests to avoid failures.

And finally, since we are using check-block.sh now again, this patch also
removes the qemu-iotests-quick.sh script since we do not need that anymore
(and having two shell wrapper scripts around the block tests seems rather
confusing than helpful).

456a2d5ac7 iotests: add testing shim for script-style python tests
Because the new-style python tests don't use the iotests.main() test
launcher, we don't turn on the debugger logging for these scripts
when invoked via ./check -d.

Refactor the launcher shim into new and old style shims so that they
share environmental configuration.

Two cleanup notes: debug was not actually used as a global, and there
was no reason to create a class in an inner scope just to achieve
default variables; we can simply create an instance of the runner with
the values we want instead.

d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

In my "build everything" tree, changing hw/qdev-properties.h triggers

objects that don't depend on qemu/osdep.h).

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h.  Include hw/qdev-core.h there
instead.

hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

cf3129323f block-backend: Queue requests while drained
This fixes devices like IDE that can still start new requests from I/O
handlers in the CPU thread while the block backend is drained.

The basic assumption is that in a drain section, no new requests should
be allowed through a BlockBackend (blk_drained_begin/end don't exist,
we get drain sections only on the node level). However, there are two
special cases where requests should not be queued:

1. Block jobs: We already make sure that block jobs are paused in a
   drain section, so they won't start new requests. However, if the
   drain_begin is called on the job's BlockBackend first, it can happen
   that we deadlock because the job stays busy until it reaches a pause
   point - which it can't if its requests aren't processed any more.

   The proper solution here would be to make all requests through the
   job's filter node instead of using a BlockBackend. For now, just
   disabling request queuing on the job BlockBackend is simpler.

2. In test cases where making requests through bdrv_* would be
   cumbersome because we'd need a BdrvChild. As we already got the
   functionality to disable request queuing from 1., use it in tests,
   too, for convenience.

Fix permissions for inactive node'). Instead of just testing
copy-on-read on migration, let's stack all sorts of filter nodes on top
of each other and try if the resulting VM can still migrate
successfully. For good measure, put everything into an iothread, because
why not?
