3568adc995 i386: Support modules_per_die in X86CPUTopoInfo
Support module level in i386 cpu topology structure "X86CPUTopoInfo".

Since x86 does not yet support the "modules" parameter in "-smp",
X86CPUTopoInfo.modules_per_die is currently always 1.

Therefore, the module level width in APIC ID, which can be calculated by
"apicid_bitwidth_for_count(topo_info->modules_per_die)", is always 0 for
now, so we can directly add APIC ID related helpers to support module
level parsing.

In addition, update topology structure in test-x86-topo.c.

9d7950edb0 hw/core: allow parameter=1 for SMP topology on any machine
This effectively reverts

  commit 54c4ea8f3a
  Author: Zhao Liu <zhao1.liu@intel.com>
  Date:   Sat Mar 9 00:01:37 2024 +0800

    hw/core/machine-smp: Deprecate unsupported "parameter=1" SMP configurations

but is not done as a 'git revert' since the part of the changes to the
file hw/core/machine-smp.c which add 'has_XXX' checks remain desirable.
Furthermore, we have to tweak the subsequently added unit test to
account for differing warning message.

The rationale for the original deprecation was:

  "Currently, it was allowed for users to specify the unsupported
   topology parameter as "1". For example, x86 PC machine doesn't
   support drawer/book/cluster topology levels, but user could specify
   "-smp drawers=1,books=1,clusters=1".

   This is meaningless and confusing, so that the support for this kind
   of configurations is marked deprecated since 9.0."

There are varying POVs on the topic of 'unsupported' topology levels.

It is common to say that on a system without hyperthreading, that there
is always 1 thread. Likewise when new CPUs introduced a concept of
multiple "dies', it was reasonable to say that all historical CPUs
before that implicitly had 1 'die'. Likewise for the more recently
introduced 'modules' and 'clusters' parameter'. From this POV, it is
valid to set 'parameter=1' on the -smp command line for any machine,
only a value > 1 is strictly an error condition.

It doesn't cause any functional difficulty for QEMU, because internally
the QEMU code is itself assuming that all "unsupported" parameters
implicitly have a value of '1'.

At the libvirt level, we've allowed applications to set 'parameter=1'
when configuring a guest, and pass that through to QEMU.

Deprecating this creates extra difficulty for because there's no info
exposed from QEMU about which machine types "support" which parameters.
Thus, libvirt can't know whether it is valid to pass 'parameter=1' for
a given machine type, or whether it will trigger deprecation messages.

Since there's no apparent functional benefit to deleting this deprecated
behaviour from QEMU, and it creates problems for consumers of QEMU,
remove this deprecation.

In test_compute_wait() we do
 double units = bkt.max / 10;
which does an integer division and then assigns it to a double variable,
and similarly later on in the expression for an assertion.

Use 10.0 so that we do a floating point division and calculate the
exact value, rather than doing an integer division.

ef88e1e875 tests/unit/test-smp-parse: Test the full 7-levels topology hierarchy
Currently, -smp supports up to 7-levels topology hierarchy:
  -drawers/books/sockets/dies/clusters/cores/threads.

Though no machine supports all these 7 levels yet, these 7 levels have
the strict containment relationship and together form the generic CPU
topology representation of QEMU.

Also, note that the maxcpus is calculated by multiplying all 7 levels:

  maxcpus = drawers * books * sockets * dies * clusters *
            cores * threads.

To cover this code path, it is necessary to test the full topology case
(with all 7 levels). This also helps to avoid introducing new issues by
further expanding the CPU topology in the future.

a58c439a2d chardev/parallel: Don't close stdin on inappropriate device
The __linux__ version of qemu_chr_open_pp_fd() tries to claim the
parport device with a PPCLAIM ioctl().  On success, it stores the file
descriptor in the chardev object, and returns success.  On failure, it
closes the file descriptor, and returns failure.

chardev_new() then passes the Chardev to object_unref().  This duly
calls char_parallel_finalize(), which closes the file descriptor
stored in the chardev object.  Since qemu_chr_open_pp_fd() didn't
store it, it's still zero, so this closes standard input.  Ooopsie.

To demonstate, add a unit test.  With the bug above unfixed, running
this test closes standard input.  char_hotswap_test() happens to run
next.  It opens a socket, duly gets file descriptor 0, and since it
tests for success with > 0 instead of >= 0, it fails.

The new unit test needs to be conditional exactly like the chardev it
tests.  Since the condition is rather complicated, steal the solution
from the serial chardev: define HAVE_CHARDEV_PARALLEL in qemu/osdep.h.
This also permits simplifying chardev/meson.build a bit.

The bug fix is easy enough: store the file descriptor, and leave
closing it to char_parallel_finalize().

The next commit will fix char_hotswap_test()'s test for success.

4b028cbe75 commit: Allow users to request only format driver names in backing file format
Introduce a new flag 'backing-mask-protocol' for the block-commit QMP
command which instructs the internals to use 'raw' instead of the
protocol driver in case when a image is used without a dummy 'raw'
wrapper.

The flag is designed such that it can be always asserted by management
tools even when there isn't any update to backing files.

The flag will be used by libvirt so that the backing images still
reference the proper format even when libvirt will stop using the dummy
raw driver (raw driver with no other config). Libvirt needs this so that
the images stay compatible with older libvirt versions which didn't
expect that a protocol driver name can appear in the backing file format
field.

e2c41766a9 tests/unit/test-iov: Fix timeout problem on NetBSD and OpenBSD
The test-iov code uses usleep() with small values (<= 30) in some
nested loops with many iterations. This causes a small delay on OSes
like Linux that have a precise sleeping mechanism, but on systems
like NetBSD and OpenBSD, each usleep() call takes multiple microseconds,
which then sum up in a total test time of multiple minutes!

Looking at the code, the usleep() does not really seem to be necessary
here - if not enough data could be send, we should simply always use
select() to wait 'til we can send more. Thus remove the usleep() and
re-arrange the code a little bit to make it more clear what is going
on here.

d0cda6f461 configure, meson: rename targetos to host_os
This variable is about the host OS, not the target.  It is used a lot
more since the Meson conversion, but the original sin dates back to 2003.
Time to fix it.

57c73988ac tests/unit/test-vmstate: Constify VMState
While const data in tests is not particularly important,
this makes a grep test clear across the tree.

b49f4755c7 block: remove AioContext locking
This is the big patch that removes
aio_context_acquire()/aio_context_release() from the block layer and
affected block layer users.

There isn't a clean way to split this patch and the reviewers are likely
the same group of people, so I decided to do it in one patch.

6bc30f1949 graph-lock: remove AioContext locking
Stop acquiring/releasing the AioContext lock in
bdrv_graph_wrlock()/bdrv_graph_unlock() since the lock no longer has any
effect.

The distinction between bdrv_graph_wrunlock() and
bdrv_graph_wrunlock_ctx() becomes meaningless and they can be collapsed
into one function.
