f4880c2da4 hw/arm: Add missing XLNX_ZYNQMP_ARM -> USB_DWC3 Kconfig dependency
Since commit acc0b8b05a when running the ZynqMP ZCU102 board with
a QEMU configured using --without-default-devices, we get:

  $ qemu-system-aarch64 -M xlnx-zcu102
  qemu-system-aarch64: missing object type 'usb_dwc3'
  Abort trap: 6

Fix by adding the missing Kconfig dependency.

Fixes: acc0b8b05a ("hw/arm/xlnx-zynqmp: Connect ZynqMP's USB controllers")

c2ecb424fb hw/arm/smmuv3: Add GBPA register
GBPA register can be used to globally abort all
transactions.

It is described in the SMMU manual in "6.3.14 SMMU_GBPA".
ABORT reset value is IMPLEMENTATION DEFINED, it is chosen to
be zero(Do not abort incoming transactions).

Other fields have default values of Use Incoming.

If UPDATE is not set, the write is ignored. This is the only permitted
behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure)

As this patch adds a new state to the SMMU (GBPA), it is added
in a new subsection for forward migration compatibility.
GBPA is only migrated if its value is different from the reset value.
It does this to be backward migration compatible if SW didn't write
the register.

dbba45e6aa tests/avocado: retire the Aarch64 TCG tests from boot_linux.py
The two TCG tests for GICv2 and GICv3 are very heavy weight distros
that take a long time to boot up, especially for an --enable-debug
build. The total code coverage they give is:

  Overall coverage rate:
    lines......: 11.2% (59584 of 530123 lines)
    functions..: 15.0% (7436 of 49443 functions)
    branches...: 6.3% (19273 of 303933 branches)

We already get pretty close to that with the machine_aarch64_virt
tests which only does one full boot (~120s vs ~600s) of alpine. We
expand the kernel+initrd boot (~8s) to test both GICs and also add an
RNG device and a block device to generate a few IRQs and exercise the
storage layer. With that we get to a coverage of:

  Overall coverage rate:
    lines......: 11.0% (58121 of 530123 lines)
    functions..: 14.9% (7343 of 49443 functions)
    branches...: 6.0% (18269 of 303933 branches)

which I feel is close enough given the massive time saving. If we want
to target any more sub-systems we can use lighter weight more directed
tests.

1b0e9b9be1 tests/tcg/s390x: Use -nostdlib for softmmu tests
The code currently uses -nostartfiles, but this does not prevent
linking with libc. On Fedora there is no cross-libc, so the linking
step fails.

Fix by using the more comprehensive -nostdlib (that's also what
probe_target_compiler() checks for as well).

As gprof relies on instrumentation you rarely get useful data compared

550c6d97de meson: Disable libdw for static builds by default
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.

74a1b256d7 configure: Bump minimum Clang version to 10.0
Anthony Perard recently reported some problems with Clang v6.0 from
Ubuntu Bionic (with regards to the -Wmissing-braces configure test).
Since we're not officially supporting that version of Ubuntu anymore,
we should better bump our minimum version check in the configure script
instead of using our time to fix problems of unsupported compilers.
According to repology.org, our supported distros ship these versions
of Clang (looking at the highest version only):

              Fedora 36: 14.0.5
      CentOS 8 (RHEL-8): 12.0.1
              Debian 11: 13.0.1
     OpenSUSE Leap 15.4: 13.0.1
       Ubuntu LTS 20.04: 12.0.0
          FreeBSD Ports: 15.0.7
          NetBSD pkgsrc: 15.0.7
               Homebrew: 15.0.7
            MSYS2 mingw: 15.0.7
            Haiku ports: 12.0.1

While it seems like we could update to v12.0.0 from that point of view,
the default version on Ubuntu 20.04 is still v10.0, and we use that for
our CI tests based via the tests/docker/dockerfiles/ubuntu2004.docker
file.

Thus let's make v10.0 our minimum version now (which corresponds to
Apple Clang version v12.0). The -Wmissing-braces check can then be
removed, too, since both our minimum GCC and our minimum Clang version
now handle this correctly.

7b548761e5 ram: Document migration ram flags
0x80 is RAM_SAVE_FLAG_HOOK, it is in qemu-file now.
Bigger usable flag is 0x200, noticing that.
We can reuse RAM_SAVe_FLAG_FULL.

cfc3bcf373 migration/multifd: Move load_cleanup inside incoming_state_destroy
Currently running migration_incoming_state_destroy() without first running
multifd_load_cleanup() will cause a yank error:

qemu-system-x86_64: ../util/yank.c:107: yank_unregister_instance:
Assertion `QLIST_EMPTY(&entry->yankfns)' failed.
(core dumped)

The above error happens in the target host, when multifd is being used
for precopy, and then postcopy is triggered and the migration finishes.
This will crash the VM in the target host.

To avoid that, move multifd_load_cleanup() inside
migration_incoming_state_destroy(), so that the load cleanup becomes part
of the incoming state destroying process.

Running multifd_load_cleanup() twice can become an issue, though, but the
only scenario it could be ran twice is on process_incoming_migration_bh().
So removing this extra call is necessary.

On the other hand, this multifd_load_cleanup() call happens way before the
migration_incoming_state_destroy() and having this happening before
dirty_bitmap_mig_before_vm_start() and vm_start() may be a need.

So introduce a new function multifd_load_shutdown() that will mainly stop
all multifd threads and close their QIOChannels. Then use this function
instead of multifd_load_cleanup() to make sure nothing else is received
before dirty_bitmap_mig_before_vm_start().

10351fbad1 migration/multifd: Join all multifd threads in order to avoid leaks
Current approach will only join threads that are still running.

For the threads not joined, resources or private memory are always kept in
the process space and never reclaimed before process end, and this risks
serious memory leaks.

This should usually not represent a big problem, since multifd migration
is usually just ran at most a few times, and after it succeeds there is
not much to be done before exiting the process.

Yet still, it should not hurt performance to join all of them.

d926f3bb2a migration/multifd: Remove unnecessary assignment on multifd_load_cleanup()
Before assigning "p->quit = true" for every multifd channel,
multifd_load_cleanup() will call multifd_recv_terminate_threads() which
already does the same assignment, while protected by a mutex.

So there is no point doing the same assignment again.

e5bac1f525 migration/multifd: Change multifd_load_cleanup() signature and usage
Since it's introduction in commit f986c3d256 ("migration: Create multifd
migration threads"), multifd_load_cleanup() never returned any value
different than 0, neither set up any error on errp.

Even though, on process_incoming_migration_bh() an if clause uses it's
return value to decide on setting autostart = false, which will never
happen.

In order to simplify the codebase, change multifd_load_cleanup() signature
to 'void multifd_load_cleanup(void)', and for every usage remove error
handling or decision made based on return value != 0.
