06ecb6ac19 docs: clean-up the xenpvh documentation
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

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.

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.

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.

6dc8a88785 docs: document what configure does with virtual environments
Given the recent confusion around how QEMU detects the system
Meson installation, and/or decides to install its own, it is
time to fill in the "Python virtual environments and the QEMU
build system" section of the documentation.

84dd7d88c9 docs/system: clarify limits of using gdbstub in system emulation
It seems some users will try and use the gdbstub to debug userspace
inside a system emulation. While possible clarify the limitations of
this approach and direct the users to a less head scratching way of
debugging user-space.

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.

c375f05ef5 sphinx/qapidoc: Tidy up pylint warning raise-missing-from
Pylint advises:

    docs/sphinx/qapidoc.py:518:12: W0707: Consider explicitly re-raising using 'raise ExtensionError(str(err)) from err' (raise-missing-from)

>From its manual:

    Python's exception chaining shows the traceback of the current
    exception, but also of the original exception.  When you raise a
    new exception after another exception was caught it's likely that
    the second exception is a friendly re-wrapping of the first
    exception.  In such cases `raise from` provides a better link
    between the two tracebacks in the final error.

Makes sense, so do it.

019233096c vhost-user.rst: Migrating back-end-internal state
For vhost-user devices, qemu can migrate the virtio state, but not the
back-end's internal state.  To do so, we need to be able to transfer
this internal state between front-end (qemu) and back-end.

At this point, this new feature is added for the purpose of virtio-fs
migration.  Because virtiofsd's internal state will not be too large, we
believe it is best to transfer it as a single binary blob after the
streaming phase.

These are the additions to the protocol:
- New vhost-user protocol feature VHOST_USER_PROTOCOL_F_DEVICE_STATE
- SET_DEVICE_STATE_FD function: Front-end and back-end negotiate a file
  descriptor over which to transfer the state.
- CHECK_DEVICE_STATE: After the state has been transferred through the
  file descriptor, the front-end invokes this function to verify
  success.  There is no in-band way (through the file descriptor) to
  indicate failure, so we need to check explicitly.

Once the transfer FD has been established via SET_DEVICE_STATE_FD
(which includes establishing the direction of transfer and migration
phase), the sending side writes its data into it, and the reading side
reads it until it sees an EOF.  Then, the front-end will check for
success via CHECK_DEVICE_STATE, which on the destination side includes
checking for integrity (i.e. errors during deserialization).

a6e76dd3c3 vhost-user.rst: Introduce suspended state
In vDPA, GET_VRING_BASE does not stop the queried vring, which is why
SUSPEND was introduced so that the returned index would be stable.  In
vhost-user, it does stop the vring, so under the same reasoning, it can
get away without SUSPEND.

Still, we do want to clarify that if the device is completely stopped,
i.e. all vrings are stopped, the back-end should cease to modify any
state relating to the guest.  Do this by calling it "suspended".

eae69cc36b vhost-user.rst: Clarify enabling/disabling vrings
Currently, the vhost-user documentation says that rings are to be
initialized in a disabled state when VHOST_USER_F_PROTOCOL_FEATURES is
negotiated.  However, by the time of feature negotiation, all rings have
already been initialized, so it is not entirely clear what this means.

At least the vhost-user-backend Rust crate's implementation interpreted
it to mean that whenever this feature is negotiated, all rings are to
put into a disabled state, which means that every SET_FEATURES call
would disable all rings, effectively halting the device.  This is
problematic because the VHOST_F_LOG_ALL feature is also set or cleared
this way, which happens during migration.  Doing so should not halt the
device.

Other implementations have interpreted this to mean that the device is
to be initialized with all rings disabled, and a subsequent SET_FEATURES
call that does not set VHOST_USER_F_PROTOCOL_FEATURES will enable all of
them.  Here, SET_FEATURES will never disable any ring.

This interpretation does not suffer the problem of unintentionally
halting the device whenever features are set or cleared, so it seems
better and more reasonable.

We can clarify this in the documentation by making it explicit that the
enabled/disabled state is tracked even while the vring is stopped.
Every vring is initialized in a disabled state, and SET_FEATURES without
VHOST_USER_F_PROTOCOL_FEATURES simply becomes one way to enable all
vrings.

c7f2181661 vhost-user.rst: Improve [GS]ET_VRING_BASE doc
GET_VRING_BASE does not mention that it stops the respective ring.  Fix
that.

Furthermore, it is not fully clear what the "base offset" these
commands' documentation refers to is; an offset could be many things.
Be more precise and verbose about it, especially given that these
commands use different payload structures depending on whether the vring
is split or packed.

13edcf591e hw/arm/vexpress-a9: Remove useless mapping of RAM at address 0
On the vexpress-a9 board we try to map both RAM and flash to address 0,
as seen in "info mtree":

address-space: memory
  0000000000000000-ffffffffffffffff (prio 0, i/o): system
    0000000000000000-0000000003ffffff (prio 0, romd): alias vexpress.flashalias @vexpress.flash0 0000000000000000-0000000003ffffff
    0000000000000000-0000000003ffffff (prio 0, ram): alias vexpress.lowmem @vexpress.highmem 0000000000000000-0000000003ffffff
    0000000010000000-0000000010000fff (prio 0, i/o): arm-sysctl
    0000000010004000-0000000010004fff (prio 0, i/o): pl041
(etc)

The flash "wins" and the RAM mapping is useless (but also harmless).

This happened as a result of commit 6ec1588e in 2014, which changed
"we always map the RAM to the low addresses for vexpress-a9" to "we
always map flash in the low addresses", but forgot to stop mapping
the RAM.

In real hardware, this low part of memory is remappable, both at
runtime by the guest writing to a control register, and configurably
as to what you get out of reset -- you can have the first flash
device, or the second, or the DDR2 RAM, or the external AXI bus
(which for QEMU means "nothing there").  In an ideal world we would
support that remapping both at runtime and via a machine property to
select the out-of-reset behaviour.

Pending anybody caring enough to implement the full remapping
behaviour:
 * remove the useless mapped-but-inaccessible lowram MR
 * document that QEMU doesn't support remapping of low memory

Fixes: 6ec1588e ("hw/arm/vexpress: Alias NOR flash at 0 for vexpress-a9")

ba7d12eb8c hw/pci: modify pci_setup_iommu() to set PCIIOMMUOps
This patch modifies pci_setup_iommu() to set PCIIOMMUOps
instead of setting PCIIOMMUFunc. PCIIOMMUFunc is used to
get an address space for a PCI device in vendor specific
way. The PCIIOMMUOps still offers this functionality. But
using PCIIOMMUOps leaves space to add more iommu related
vendor specific operations.

  The qdev conversion in this pull request ("stellaris-gamepad: Convert
  to qdev") eliminates the vmstate_register() call that was converted to
  vmstate_register_any() in the conflicting migration pull request.
  vmstate_register_any() is no longer necessary now that this device has
  been converted to qdev, so take this pull request's version of
  stellaris_gamepad.c over the previous pull request's
  stellaris_input.c (the file was renamed).

bb1cff6ee0 docs/specs/ivshmem-spec: Convert to rST
Convert docs/specs/ivshmem-spec.txt to rST format.

In converting, I have dropped the sections on the device's command
line interface and usage, as they are already covered by the
user-facing docs in system/devices/ivshmem.rst.

I have also removed the reference to Memnic, because the URL is dead
and a web search suggests that whatever this was it's pretty much
sunk without trace.

26ea27898b qemu-img: add compression option to rebase subcommand
If we rebase an image whose backing file has compressed clusters, we
might end up wasting disk space since the copied clusters are now
uncompressed.  In order to have better control over this, let's add
"--compress" option to the "qemu-img rebase" command.

Note that this option affects only the clusters which are actually being
copied from the original backing file.  The clusters which were
uncompressed in the target image will remain so.
