Philippe Mathieu-Daudé 2d9e45b9cb gitlab: Convert check-dco/check-patch jobs to the 'rules' syntax
Per GitLab documentation [*]:

  "rules replaces only/except and they can’t be used together
   in the same job."

Since the 'rules' syntax is more powerful and we are already using
it, convert the check-dco/check-patch jobs so no job use the 'only/
except' syntax.

Philippe Mathieu-Daudé 1f88fad50e gitlab: Use $CI_DEFAULT_BRANCH instead of hardcoded 'master'
We want to skip the checkpatch and DCO signoff jobs when
pushing to the default branch. Currently this branch is
called 'master', but we don't need to hardcode this in
the CI configuration, because the $CI_DEFAULT_BRANCH
env variable exposes it.

Philippe Mathieu-Daudé f56bf4caf7 gitlab: Run Avocado tests manually (except mainstream CI)
Due to a design problem and misunderstanding between the Avocado
framework and QEMU, Avocado is fetching many asset artifacts it
shouldn't be fetching, exhausting the jobs CI timeout.

Since Avocado artifacts are cached, this is not an issue with old
forks, which already have populated the cache and do not need to
download new artifacts to run the tests.

However this is very confusing to new contributors who start to
fork the project and keep having failing CI pipelines.

As a temporary kludge, add the QEMU_CI_AVOCADO_TESTING variable
to allow old forks to keep running the Avocado tests, while still
allowing new forks to use the mainstream set of CI tests.

Keep the tests enabled by default on the mainstream namespace
which is old enough to have a populated cache, hoping we will
keep this cache long enough until the Avocado/QEMU design issue
is fixed.

Philippe Mathieu-Daudé f230dba714 gitlab: Keep Avocado reports during 1 week
Sometimes pull requests are merged during the week-end, triggering
a CI pipeline. Currently if such pipeline fails, the Avocado reports
are available for 2 days. For the reviewers working on the project
during office hours, the reports are already discarded when they
want to look at them. Increase this time to 1 week, which should
give reviewers enough time.

Only keep the reports on failure, which is the only case we'll
look at them.

Daniel P. Berrangé dcaf5e8f2f gitlab: Drop linux user build job for CentOS 7
It has been over two years since RHEL-8 was released, and thus per the
platform build policy, we no longer need to support RHEL-7 as a build
target.

The build-user-centos7 job was to detect a failure specific to CentOS
7 and there are already other linux user jobs for other platforms.
Thus we can drop this job rather than move it to CentOS 8.

Laurent Vivier 1e157667d7 virtio-net: failover: add missing remove_migration_state_change_notifier()
In the failover case configuration, virtio_net_device_realize() uses an
add_migration_state_change_notifier() to add a state notifier, but this
notifier is not removed by the unrealize function when the virtio-net
card is unplugged.

If the card is unplugged and a migration is started, the notifier is
called and as it is not valid anymore QEMU crashes.

This patch fixes the problem by adding the
remove_migration_state_change_notifier() in virtio_net_device_unrealize().

The problem can be reproduced with:

  $ qemu-system-x86_64 -enable-kvm -m 1g -M q35 \
    -device pcie-root-port,slot=4,id=root1 \
    -device pcie-root-port,slot=5,id=root2 \
    -device virtio-net-pci,id=net1,mac=52:54:00:6f:55:cc,failover=on,bus=root1 \
    -monitor stdio disk.qcow2
  (qemu) device_del net1
  (qemu) migrate "exec:gzip -c > STATEFILE.gz"

Guenter Roeck f607dce2ed hw/net/imx_fec: return 0xffff when accessing non-existing PHY
If a PHY does not exist, attempts to read from it should return 0xffff.
Otherwise the Linux kernel will believe that a PHY is there and select
the non-existing PHY. This in turn will result in network errors later
on since the real PHY is not selected or configured.

Since reading from or writing to a non-existing PHY is not an emulation
error, replace guest error messages with traces.

Philippe Mathieu-Daudé 744c72a837 cpu: Rename CPUClass vmsd -> legacy_vmsd
Quoting Peter Maydell [*]:

  There are two ways to handle migration for
  a CPU object:

  (1) like any other device, so it has a dc->vmsd that covers
  migration for the whole object. As usual for objects that are a
  subclass of a parent that has state, the first entry in the
  VMStateDescription field list is VMSTATE_CPU(), which migrates
  the cpu_common fields, followed by whatever the CPU's own migration
  fields are.

  (2) a backwards-compatible mechanism for CPUs that were
  originally migrated using manual "write fields to the migration
  stream structures". The on-the-wire migration format
  for those is based on the 'env' pointer (which isn't a QOM object),
  and the cpu_common part of the migration data is elsewhere.

  cpu_exec_realizefn() handles both possibilities:

  * for type 1, dc->vmsd is set and cc->vmsd is not,
    so cpu_exec_realizefn() does nothing, and the standard
    "register dc->vmsd for a device" code does everything needed

  * for type 2, dc->vmsd is NULL and so we register the
    vmstate_cpu_common directly to handle the cpu-common fields,
    and the cc->vmsd to handle the per-CPU stuff

  You can't change a CPU from one type to the other without breaking
  migration compatibility, which is why some guest architectures
  are stuck on the cc->vmsd form. New targets should use dc->vmsd.

To avoid new targets to start using type (2), rename cc->vmsd as
cc->legacy_vmsd. The correct field to implement is dc->vmsd (the
DeviceClass one).

See also commit b170fce3dd ("cpu: Register VMStateDescription
through CPUState") for historic background.

The current cpu.c contains sysemu-specific methods.
To avoid building them in user-mode builds, split the
current cpu.c as cpu-common.c / cpu-sysemu.c.

Start by moving cpu_get_crash_info().

Yasuo Kuwahara 26b1248f66 tcg/aarch64: Fix tcg_out_rotl
The last argument of tcg_out_extr() must be in the range 0-31 if ext==0.
Before the fix, when m==0 it becomes 32 and it crashes with an Illegal
instruction on Apple Silicon.  After the fix, it will be 0.  If m is in
the range 1-31, it is the same as before.

Pavel Dovgalyuk 57dcb643d7 replay: fix watchpoint processing for reverse debugging
This patch enables reverse debugging with watchpoints.
Reverse continue scans the execution to find the breakpoints
and watchpoints that should fire. It uses helper function
replay_breakpoint() for that. But this function needs to access
icount, which can't be correct in the middle of TB.
Therefore, in case of watchpoint, we have to retranslate the block
to allow this access.

Philippe Mathieu-Daudé e5ceadff47 accel/tcg: Keep TranslationBlock headers local to TCG
Only the TCG accelerator uses the TranslationBlock API.
Move the tb-context.h / tb-hash.h / tb-lookup.h from the
global namespace to the TCG one (in accel/tcg).
