Yihuan PanandThomas Huth fd49b2153e qemu-options: Clarify handling of commas in options parameters
Provide explicit guidance on dealing with option parameters as arbitrary
strings containing commas, such as in "file=my,file" and "string=a,b". The
updated documentation emphasizes the need to double commas when they
appear within such parameters.

Markus ArmbrusterandThomas Huth c455e011c6 hw: Replace anti-social QOM type names (again)
QOM type names containing ',' result in awful UI.  We got rid of them
in v6.0.0 (commit e178113ff6 hw: Replace anti-social QOM type names).
A few have crept back since:

    xlnx,cframe-reg
    xlnx,efuse
    xlnx,pmc-efuse-cache
    xlnx,versal-cfu-apb
    xlnx,versal-cfu-fdro
    xlnx,versal-cfu-sfr
    xlnx,versal-crl
    xlnx,versal-efuse
    xlnx,zynqmp-efuse

These are all device types.  They can't be plugged with -device /
device_add, except for "xlnx,efuse" (I'm not sure that one is
intentional).

They *can* be used with -device / device_add to request help.
Usability is poor, though: you have to double the comma, like this:

    $ qemu-system-aarch64 -device xlnx,,pmc-efuse-cache,help

They can also be used with -global, where you must *not* double the
comma:

    $ qemu-system-aarch64 -global xlnx,efuse.drive-index=2

Trap for the unwary.

"xlnx,efuse", "xlnx,versal-efuse", "xlnx,pmc-efuse-cache",
"xlnx-zynqmp-efuse" are from v6.2.0, "xlnx,versal-crl" is from v7.1.0,
and the remainder are new.

Rename them all to "xlnx-FOO", like commit e178113ff6 did.

I noticed the code blocks where not rendering properly so thought I'd
better fix things up. So:

  - Use better title for the machine type
  - Explain why Xen is a little different
  - Add a proper anchor to the tpm-device link
  - add newline so code block properly renders
  - add some indentation to make continuation clearer

Alex Bennée 5d25fcb702 gitlab: add optional job to run flaky avocado tests
One problem with flaky tests is they often only fail under CI
conditions which makes it hard to debug. We add an optional allow_fail
job so developers can trigger the only the flaky tests in the CI
environment if they are debugging.

Alex Bennée 9b45cc9931 docs/devel: rationalise unstable gitlab tests under FLAKY_TESTS
It doesn't make sense to have two classes of flaky tests. While it may
take the constrained environment of CI to trigger failures easily it
doesn't mean they don't occasionally happen on developer machines. As
CI is the gating factor to passing there is no point developers
running the tests locally anyway unless they are trying to fix things.

While we are at it update the language in the docs to discourage the
QEMU_TEST_FLAKY_TESTS becoming a permanent solution.

Zhao LiuandPhilippe Mathieu-Daudé 0180a74463 docs/s390: Fix wrong command example in s390-cpu-topology.rst
From s390_possible_cpu_arch_ids() in hw/s390x/s390-virtio-ccw.c, the
"core-id" is the index of possible_cpus->cpus[], so it should only be
less than possible_cpus->len, which is equal to ms->smp.max_cpus.

Fix the wrong "core-id" 112, because it isn't less than maxcpus (36) in
-smp, and the valid core ids are 0-35 inclusive.

Richard Henderson cf9b5790db accel/tcg: Remove CF_LAST_IO
In cpu_exec_step_atomic, we did not set CF_LAST_IO, which lead
to a loop with cpu_io_recompile.

But since 18a536f1f8 ("Always require can_do_io") we no longer
need a flag to indicate when the last insn should have can_do_io set,
so remove the flag entirely.
