7100fe6c24 target/riscv: Enable privileged spec version 1.12
Virt machine uses privileged specification version 1.12 now.
All other machine continue to use the default one defined for that
machine unless changed to 1.12 by the user explicitly.

This commit enforces the privilege version for csrs introduced in
v1.12 or after.

29a9ec9bd8 target/riscv: Add *envcfg* CSRs support
The RISC-V privileged specification v1.12 defines few execution
environment configuration CSRs that can be used enable/disable
extensions per privilege levels.

Add the basic support for these CSRs.

3e6a417c8a target/riscv: Add support for mconfigptr
RISC-V privileged specification v1.12 introduced a mconfigptr
which will hold the physical address of a configuration data
structure. As Qemu doesn't have a configuration data structure,
is read as zero which is valid as per the priv spec.

a4b2fa4331 target/riscv: Introduce privilege version field in the CSR ops.
To allow/disallow the CSR access based on the privilege spec, a new field
in the csr_ops is introduced. It also adds the privileged specification
version (v1.12) for the CSRs introduced in the v1.12. This includes the
new ratified extensions such as Vector, Hypervisor and secconfig CSR.
However, it doesn't enforce the privilege version in this commit.

552de79bfd migration: Read state once
The 'status' field for the migration is updated normally using
an atomic operation from the migration thread.
Most readers of it aren't that careful, and in most cases it doesn't
matter.

In query_migrate->fill_source_migration_info the 'state'
is read twice; the first time to decide which state fields to fill in,
and then secondly to copy the state to the status field; that can end up
with a status that's inconsistent; e.g. setting up the fields
for 'setup' and then having an 'active' status.  In that case
libvirt gets upset by the lack of ram info.
The symptom is:
   libvirt.libvirtError: internal error: migration was active, but no RAM info was set

Read the state exactly once in fill_source_migration_info.

This is a possible fix for:

08401c0426 migration: Allow migrate-recover to run multiple times
Previously migration didn't have an easy way to cleanup the listening
transport, migrate recovery only allows to execute once.  That's done with a
trick flag in postcopy_recover_triggered.

Now the facility is already there.

Drop postcopy_recover_triggered and instead allows a new migrate-recover to
release the previous listener transport.

a39e933962 migration: Move channel setup out of postcopy_try_recover()
We used to use postcopy_try_recover() to replace migration_incoming_setup() to
setup incoming channels.  That's fine for the old world, but in the new world
there can be more than one channels that need setup.  Better move the channel
setup out of it so that postcopy_try_recover() only handles the last phase of
switching to the recovery phase.

To do that in migration_fd_process_incoming(), move the postcopy_try_recover()
call to be after migration_incoming_setup(), which will setup the channels.
While in migration_ioc_process_incoming(), postpone the recover() routine right
before we'll jump into migration_incoming_process().

A side benefit is we don't need to pass in QEMUFile* to postcopy_try_recover()
anymore.  Remove it.

83174765da migration: Postpone releasing MigrationState.hostname
We used to release it right after migrate_fd_connect().  That's not good
enough when there're more than one socket pair required, because it'll be

One example is multifd, where we copied over the hostname for each channel
but that's actually not needed.

Keeping the hostname until the cleanup phase of migration.

b3caa7b55e tests: introduce ability to provide hooks for migration precopy test
There are alot of different scenarios to test with migration due to the
wide number of parameters and capabilities available. To enable sharing
of the basic precopy test scenario, we need to be able to set arbitrary
parameters and capabilities before the migration is initiated, but don't
want to have all this logic in the common helper function. Solve this
by defining two hooks that can be provided by the test case, one before
migration starts and one after migration finishes.

19da6edfe8 tests: switch MigrateStart struct to be stack allocated
There's no compelling reason why the MigrateStart struct needs to be
heap allocated. Using stack allocation and static initializers is
simpler.

4b2bbca7a0 migration: fix use of TLS PSK credentials with a UNIX socket
The migration TLS code has a check mandating that a hostname be
available when starting a TLS session. This is expected when using
x509 credentials, but is bogus for PSK and anonymous credentials
as neither involve hostname validation.

The TLS crdentials object gained suitable error reporting in the
case of TLS with x509 credentials, so there is no longer any need
for the migration code to do its own (incorrect) validation.

0c2b6c85c9 tests: print newline after QMP response in qtest logs
The QMP commands have a trailing newline, but the response does not.
This makes the qtest logs hard to follow as the next QMP command
appears in the same line as the previous QMP response.

724eaecec6 target/rx: update PC correctly in wait instruction
`cpu_pc` at this point does not necessary point to the current
instruction (i.e., the wait instruction being translated), so it's
incorrect to calculate the new value of `cpu_pc` based on this. It must
be updated with `ctx->base.pc_next`, which contains the correct address
of the next instruction.

This change fixes the wait instruction skipping the subsequent branch
when used in an idle loop like this:

    0:  wait
        bra.b 0b
        brk   // should be unreachable

47430775ed python/qmp: remove pylint workaround from legacy.py
Pylint upgraded recently (2.13.z) and having a pylint: disable comment
in the middle of an argument field causes it some grief (It appears to
stop parsing when it encounters it, causing some syntax problems). Since
the duplicate line threshold was bumped up in 22305c2a08, we don't
need this workaround anymore. Drop it.

37094b6dd5 python: rename qemu.aqmp to qemu.qmp
Now that we are fully switched over to the new QMP library, move it back
over the old namespace. This is being done primarily so that we may
upload this package simply as "qemu.qmp" without introducing confusion
over whether or not "aqmp" is a new protocol or not.

The trade-off is increased confusion inside the QEMU developer
tree. Sorry!

Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp";
not out of necessity, but just to remove any traces of the "aqmp"
name.

445c9d4e3d python/aqmp-tui: relicense as LGPLv2+
aqmp-tui, the async QMP text user interface tool, is presently licensed
as GPLv2+. I intend to include this tool as an add-on to an LGPLv2+
library package hosted on PyPI.org. I've selected LGPLv2+ to maximize
compatibility with other licenses while retaining a copyleft license.

To keep licensing matters simple, I'd like to relicense this tool as
LGPLv2+ as well in order to keep the resultant license of the hosted
release files simple -- even if library users won't "link against" this
command line tool.

Therefore, I am asking permission to loosen the license.

Niteesh is effectively the sole author of this code, with scattered
lines from myself.

this tool as an add-on to an LGPLv2+ library package hosted on
PyPI.org. I've selected LGPLv2+ to maximize compatibility with other
licenses while retaining a copyleft license.

To keep licensing matters simple, I'd like to relicense this tool as
LGPLv2+ as well in order to keep the resultant license of the hosted
release files simple -- even if library users won't "link against" this
command line tool.

Therefore, I am asking permission from the current authors of this
tool to loosen the license. At present, those people are:

- John Snow (me!), 411/609
- Luiz Capitulino, Author, 97/609
- Daniel Berrangé, 81/609
- Eduardo Habkost, 10/609
- Marc-André Lureau, 6/609
- Fam Zheng, 3/609
- Cleber Rosa, 1/609

(All of which appear to have been written under redhat.com addresses.)

Eduardo's fixes are largely automated from 2to3 conversion tools and may
not necessarily constitute authorship, but his signature would put to
rest any questions.

Cleber's changes concern a single import statement change. Also won't
hurt to ask.

9dcea96d08 python/aqmp: relicense as LGPLv2+
I am the sole author of all of the async QMP code (python/qemu/aqmp)
with the following exceptions:

python/qemu/aqmp/qmp_shell.py and python/qemu/aqmp/legacy.py were
written by Luiz Capitulino (et al) and are already licensed separately
as GPLv2 (only).

aqmp_tui.py was written by Niteesh Babu G S and is licensed as GPLv2+.

I wish to relicense as LGPLv2+ in order to provide as much flexibility
as I reasonably can, while retaining a copyleft license. It is my belief
that LGPLv2+ is a suitable license for the Python ecosystem that aligns
with the goals and philosophy of the QEMU project.

The intent is to eventually drop legacy.py, leaving only library code
that is LGPLv2+.
