Add zoned device option to host_device BlockDriver. It will be presented only
for zoned host block devices. By adding zone management operations to the
host_block_device BlockDriver, users can use the new block layer APIs
including Report Zone and four zone management operations
(open, close, finish, reset, reset_all).
Qemu-io uses the new APIs to perform zoned storage commands of the device:
zone_report(zrp), zone_open(zo), zone_close(zc), zone_reset(zrs),
zone_finish(zf).
For example, to test zone_report, use following command:
$ ./build/qemu-io --image-opts -n driver=host_device, filename=/dev/nullb0
-c "zrp offset nr_zones"

meson.build files choose whether to build modules based on foo.found()
expressions. If a feature is enabled (e.g. --enable-gtk), these expressions
are true even if the code is not used by any emulator, and this results
in an unexpected difference between modular and non-modular builds.
For non-modular builds, the files are not included in any binary, and
therefore the source files are never processed. For modular builds,
however, all .so files are unconditionally built by default, and therefore
a normal "make" tries to build them. However, the corresponding trace-*.h
files are absent due to this conditional:
if have_system
trace_events_subdirs += [
...
'ui',
...
]
endif
which was added to avoid wasting time running tracetool on unused trace-events
files. This causes a compilation failure; fix it by skipping module builds
entirely if (depending on the module directory) have_block or have_system
are false.

This commit adds a new audiodev backend to allow QEMU to use Pipewire as
both an audio sink and source. This backend is available on most systems
Add Pipewire entry points for QEMU Pipewire audio backend
Add wrappers for QEMU Pipewire audio backend in qpw_pcm_ops()
qpw_write function returns the current state of the stream to pwaudio
and Writes some data to the server for playback streams using pipewire
spa_ringbuffer implementation.
qpw_read function returns the current state of the stream to pwaudio and
reads some data from the server for capture streams using pipewire
spa_ringbuffer implementation. These functions qpw_write and qpw_read
are called during playback and capture.
Added some functions that convert pw audio formats to QEMU audio format
and vice versa which would be needed in the pipewire audio sink and
source functions qpw_init_in() & qpw_init_out().
These methods that implement playback and recording will create streams
for playback and capture that will start processing and will result in
the on_process callbacks to be called.
Built a connection to the Pipewire sound system server in the
qpw_audio_init() method.

The XEN_EMU option will cover core Xen support in target/, which exists
only for x86 with KVM today but could theoretically also be implemented
on Arm/Aarch64 and with TCG or other accelerators (if anyone wants to
run the gauntlet of struct layout compatibility, errno mapping, and the
rest of that fui).
It will also cover the support for architecture-independent grant table
and event channel support which will be added in hw/i386/kvm/ (on the
basis that the non-KVM support is very theoretical and making it not use
KVM directly seems like gratuitous overengineering at this point).
The XEN_BUS option is for the xenfv platform support, which will now be
used both by XEN_EMU and by real Xen.
The XEN option remains dependent on the Xen runtime libraries, and covers
support for real Xen. Some code which currently resides under CONFIG_XEN
will be moving to CONFIG_XEN_BUS over time as the direct dependencies on
Xen runtime libraries are eliminated. The Xen PCI platform device will
also reside under CONFIG_XEN_BUS.

Fork-fuzzing provides a few pros, but our implementation prevents us
from using fuzzers other than libFuzzer, and may be causing issues such
as coverage-failure builds on OSS-Fuzz. It is not a great long-term
solution as it depends on internal implementation details of libFuzzer
(which is no longer in active development). Remove it in favor of other
methods of resetting state between inputs.

As gprof relies on instrumentation you rarely get useful data compared

Static QEMU build fails on Debian Bullseye:
/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libdw.a(debuginfod-client.o): in function `__libdwfl_debuginfod_init':
(.text.startup+0x17): undefined reference to `dlopen'
The reason is that pkg-config does not suggest -ldl for libdw, and
adding --extra-ldflags="-ldl" resolves the issue. However, static
linking with libdw is an unclear topic:
* Linux perf does it.
* Debian's libdw-dev description says:
Only link to the static version for special cases and when you
don't need anything from the ebl backends.
* As the error message above indicates, -ldl is also needed for
debuginfod support.
The functionality provided by libdw is needed for analyzing performance
of JITed code, which is mostly useful to developers and researchers.
Therefore, in order to avoid unpleasant surprises for people who don't
need this, simply disable libdw for static builds by default. It can
still be enabled explicitly if needed.

support and benchmark for this feature are added. Compared with C
version of xbzrle_encode_buffer function, avx512 version can achieve
50%-70% performance improvement on benchmarking. In addition, if dirty

This reverts commit 3cd3df2a95.
glibc has fixed (in 2.36.9000-40-g774058d729) the problem
that caused a clash when both sys/mount.h annd linux/mount.h
are included, and backported this to the 2.36 stable release
too:
https://sourceware.org/glibc/wiki/Release/2.36#Usage_of_.3Clinux.2Fmount.h.3E_and_.3Csys.2Fmount.h.3E
It is saner for QEMU to remove the workaround it applied for
glibc 2.36 and expect distros to ship the 2.36 maint release
with the fix. This avoids needing to add a further workaround
to QEMU to deal with the fact that linux/brtfs.h now also pulls
in linux/mount.h via linux/fs.h since Linux 6.1

In Meson 0.64, the optimization built-in option now accepts the "plain" value,
which will not set any optimization flags. While QEMU does not check the
contents of the option and therefore does not suffer any ill effect
from the new value, it uses get_option to print the optimization flags
in the summary. Clean the code up to remove duplication, and check for
-Doptimization=plain at the same time.

meson.build has been enabling ASLR _only_ for debug builds since
commit d2147e04f9 ("configure: move Windows flags detection to meson",
2022-05-07); instead it was supposed to disable it for debug builds.
However, the flag has been enabled for DLLs upstream for roughly 2
years (https://sourceware.org/bugzilla/show_bug.cgi?id=19011), and
also by some distros including Debian for 6 years even
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=836365).
Enable it unconditionally; we can fix the reversed logic of commit
d2147e04f9 later if there are any reports, but for now just
enable the hardening.
Also add -Wl,--high-entropy-va, which also controls ASLR.

If a memory-backend is configured with mode
HOST_MEM_POLICY_PREFERRED then
host_memory_backend_memory_complete() calls mbind() as:
mbind(..., MPOL_PREFERRED, nodemask, ...);
Here, 'nodemask' is a bitmap of host NUMA nodes and corresponds
to the .host-nodes attribute. Therefore, there can be multiple
nodes specified. However, the documentation to MPOL_PREFERRED
says:
MPOL_PREFERRED
This mode sets the preferred node for allocation. ...
If nodemask specifies more than one node ID, the first node
in the mask will be selected as the preferred node.
Therefore, only the first node is honored and the rest is
silently ignored. Well, with recent changes to the kernel and
numactl we can do better.
The Linux kernel added in v5.15 via commit cfcaa66f8032
("mm/hugetlb: add support for mempolicy MPOL_PREFERRED_MANY")
support for MPOL_PREFERRED_MANY, which accepts multiple preferred
NUMA nodes instead.
Then, numa_has_preferred_many() API was introduced to numactl
(v2.0.15~26) allowing applications to query kernel support.
Wiring this all together, we can pass MPOL_PREFERRED_MANY to the
mbind() call instead and stop ignoring multiple nodes, silently.
