Mark Cave-Ayland 8660df5ea2 g364fb: add VMStateDescription for G364SysBusState
Currently when QEMU attempts to migrate the MIPS magnum machine it crashes due
to a mistake in the g364fb VMStateDescription configuration which expects a
G364SysBusState and not a G364State.

Resolve the issue by adding a new VMStateDescription for G364SysBusState and
embedding the existing vmstate_g364fb VMStateDescription inside it using
VMSTATE_STRUCT.

Mark Cave-Ayland d5bfbaca39 g364fb: use RAM memory region for framebuffer
Since the migration stream is already broken, we can use this opportunity to
change the framebuffer so that it is migrated as a RAM memory region rather
than as an array of bytes.

In particular this helps the output of the analyze-migration.py tool which
no longer contains a huge array representing the framebuffer contents.

Philippe Mathieu-Daudé 711ef33731 hw/pci-host/bonito: Allow PCI config accesses smaller than 32-bit
When running the official PMON firmware for the Fuloong 2E, we see
8-bit and 16-bit accesses to PCI config space:

  $ qemu-system-mips64el -M fuloong2e -bios pmon_2e.bin \

Also this is what the Linux kernel does since it supports the Bonito
north bridge:
https://elixir.bootlin.com/linux/v2.6.15/source/arch/mips/pci/ops-bonito64.c#L85

So it seems safe to assume the datasheet is incomplete or outdated
regarding the address constraints.

This problem was exposed by commit 911629e6d3
("vt82c686: Fix SMBus IO base and configuration registers").

The device model batching its ioeventfds in a single MR transaction is
an optimization. Clarify this in virtio-scsi, virtio-blk and generic
virtio code. Also clarify that the transaction must commit before
closing ioeventfds so that no one is tempted to merge the loops
in the start functions error path and in the stop functions.

Peter Maydell 0aa4b4c358 target/arm: Implement MVE long shifts by register
Implement the MVE long shifts by register, which perform shifts on a
pair of general-purpose registers treated as a 64-bit quantity, with
the shift count in another general-purpose register, which might be
either positive or negative.

Like the long-shifts-by-immediate, these encodings sit in the space
that was previously the UNPREDICTABLE MOVS/ORRS with Rm==13,15.
Because LSLL_rr and ASRL_rr overlap with both MOV_rxri/ORR_rrri and
also with CSEL (as one of the previously-UNPREDICTABLE Rm==13 cases),
we have to move the CSEL pattern into the same decodetree group.

Peter Maydell f4ae6c8cbd target/arm: Implement MVE long shifts by immediate
The MVE extension to v8.1M includes some new shift instructions which
sit entirely within the non-coprocessor part of the encoding space
and which operate only on general-purpose registers.  They take up
the space which was previously UNPREDICTABLE MOVS and ORRS encodings
with Rm == 13 or 15.

Implement the long shifts by immediate, which perform shifts on a
pair of general-purpose registers treated as a 64-bit quantity, with
an immediate shift count between 1 and 32.

Awkwardly, because the MOVS and ORRS trans functions do not UNDEF for
the Rm==13,15 case, we need to explicitly emit code to UNDEF for the
cases where v8.1M now requires that.  (Trying to change MOVS and ORRS
is too difficult, because the functions that generate the code are
shared between a dozen different kinds of arithmetic or logical
instruction for all A32, T16 and T32 encodings, and for some insns
and some encodings Rm==13,15 are valid.)

We make the helper functions we need for UQSHLL and SQSHLL take
a 32-bit value which the helper casts to int8_t because we'll need
these helpers also for the shift-by-register insns, where the shift
count might be < 0 or > 32.

Peter Maydell 303db86fc7 target/arm: Fix bugs in MVE VRMLALDAVH, VRMLSLDAVH
The initial implementation of the MVE VRMLALDAVH and VRMLSLDAVH
insns had some bugs:
 * the 32x32 multiply of elements was being done as 32x32->32,
   not 32x32->64
 * we were incorrectly maintaining the accumulator in its full
   72-bit form across all 4 beats of the insn; in the pseudocode
   it is squashed back into the 64 bits of the RdaHi:RdaLo
   registers after each beat

In particular, fixing the second of these allows us to recast
the implementation to avoid 128-bit arithmetic entirely.

Since the element size here is always 4, we can also drop the
parameterization of ESIZE to make the code a little more readable.

Nolan Leake 38f2cfbbc3 hw/arm: Add basic power management to raspi.
This is just enough to make reboot and poweroff work. Works for
linux, u-boot, and the arm trusted firmware. Not tested, but should
work for plan9, and bare-metal/hobby OSes, since they seem to generally
do what linux does for reset.

The watchdog timer functionality is not yet implemented.

Philippe Mathieu-Daudé d507663151 target/mips: Add declarations for generic TCG helpers
We want to extract the microMIPS ISA and Code Compaction ASE to
new compilation units.

We will first extract this code as included source files (.c.inc),
then make them new compilation units afterward.

The following methods are going to be used externally:

  micromips_translate.c.inc:1778:   gen_ldxs(ctx, rs, rt, rd);
  micromips_translate.c.inc:1806:   gen_align(ctx, 32, rd, rs, ...
  micromips_translate.c.inc:2859:   gen_addiupc(ctx, reg, offset, ...
  mips16e_translate.c.inc:444:      gen_addiupc(ctx, ry, offset, ...

To avoid too much code churn, it is simpler to declare these
prototypes in "translate.h" now.

John Snow 5c02c86586 python: Fix broken ReST docstrings
This patch *doesn't* update all of the docstring standards across the
QEMU package directory to make our docstring usage consistent. It
*doesn't* fix the formatting to make it look pretty or reasonable in
generated output. It *does* fix a few small instances where Sphinx would
emit a build warning because of malformed ReST -- If we built our Python
docs with Sphinx.

John Snow 19cf0031e4 python: remove auto-generated pyproject.toml file
For reasons that at-present escape me, pipenv insists on creating a stub
pyproject.toml file. This file is a nuisance, because its mere presence
changes the behavior of various tools.

For instance, this stub file will cause "pip install --user -e ." to
fail in spectacular fashion with misleading errors. "pip install -e ."
works okay, but for some reason pip does not support editable installs
to the user directory when using PEP517.

References:
  https://github.com/pypa/pip/pull/9990
  https://github.com/pypa/pip/issues/7953

As outlined in ea1213b7cc, it is still too early for us to consider
moving to a PEP-517 exclusive package. We must support older
distributions, so squash the annoyance for now. (Python 3.6 shipped Dec
2016, PEP517 support showed up in pip sometime in 2019 or so.)

Add 'pyproject.toml' to the 'make clean' target, and also delete it
after every pipenv invocation issued by the Makefile.

John Snow 2c24d52d06 python: add 'make check-dev' invocation
This is a *third* way to run the Python tests. Unlike the first two
(check-pipenv, check-tox), this version does not require any specific
interpreter version -- making it a lot easier to tell people to run it
as a quick smoketest prior to submission to GitLab CI.

Summary:

  Checked via GitLab CI:
    - check-pipenv: tests our oldest python & dependencies
    - check-tox: tests newest dependencies on all non-EOL python versions
  Executed only incidentally:
    - check-dev: tests newest dependencies on whichever python version

('make check' does not set up any environment at all, it just runs the
tests in your current environment. All four invocations perform the
exact same tests, just in different execution environments.)

John Snow 0d52c19a59 python: only check qemu/ subdir with flake8
flake8 is a little eager to check everything it can. Limit it to
checking inside the qemu namespace directory only. Update setup.cfg now
that the exclude patterns are no longer necessary.

John Snow 205d7219f3 python: Fix .PHONY Make specifiers
I missed the 'check-tox' target. Add that, but split the large .PHONY
specifier at the top into its component pieces and move them near the
targets they describe so that they're much harder to forget to update.

John Snow 8c95d0fc7f python: update help text for check-tox
Move it up near the check-pipenv help text, and update it to suggest parity.

(At the time I first added it, I wasn't sure if I would be keeping it,
but I've come to appreciate it as it has actually helped uncover bugs I
would not have noticed without it. It should stay.)

John Snow 6f84d726f3 python: rename 'venv-check' target to 'check-pipenv'
Well, Cleber was right, this is a better name.

In preparation for adding a different kind of virtual environment check
(One that simply uses whichever version of Python you happen to have),
rename this test 'check-pipenv' so that it matches the CI job
'check-python-pipenv'.

Remove the "If you don't know which test to run" hint, because it's not
actually likely you have Python 3.6 installed to be able to run the
test. It's still the test I'd most prefer you to run, but it's not the
test you are most likely to be able to run.

Rename the 'venv' target to 'pipenv' as well, and move the more
pertinent help text under the 'check-pipenv' target.

John Snow 4176dbd8b5 python: README.rst touchups
Clarifying a few points; removing the reference to 'setuptools' because
it isn't referenced anywhere else in this document and doesn't really
provide any useful information to a Python newcomer.

Adjusting the language elsewhere to be less ambiguous and have fewer
run-on sentences.
