RISC-V privilege spec defines that mtime is exposed as a memory-mapped
machine-mode read-write register. However, as QEMU uses host monotonic
timer as timer source, this makes mtime to be read-only in RISC-V
ACLINT.
This patch makes mtime to be writable by recording the time delta value
between the mtime value to be written and the timer value at the time
mtime is written. Time delta value is then added back whenever the timer
value is retrieved.

However, the riscv cpu device tree binding [1] has a specific value
"riscv,none" for a HART without a MMU.
Set the device tree property "mmu-type" to "riscv,none" when the CPU mmu

The Linux kernel parses the ISA extensions from "riscv,isa" DT
property. It used to parse only the single letter base extensions
until now. A generic ISA extension parsing framework was proposed[1]
recently that can parse multi-letter ISA extensions as well.
Generate the extended ISA string by appending the available ISA extensions
to the "riscv,isa" string if it is enabled so that kernel can process it.

Some bits in RISC-V `misa' CSR should not be reflected in the ISA
string. For instance, `S' and `U' (represents existence of supervisor

neither `S' nor `U' are valid single-letter extensions.
This commit also removes all reserved/dropped single-letter "extensions"
from the list.
- "B": Not going to be a single-letter extension (misa.B is reserved).
- "J": Not going to be a single-letter extension (misa.J is reserved).
- "K": Not going to be a single-letter extension (misa.K is reserved).

The RISC-V specification states that:
"Supervisor-level external interrupts are made pending based on the
logical-OR of the software-writable SEIP bit and the signal from the
external interrupt controller."
We currently only allow either the interrupt controller or software to
set the bit, which is incorrect.
This patch removes the miclaim mask when writing MIP to allow M-mode
software to inject interrupts, even with an interrupt controller.
We then also need to keep track of which source is setting MIP_SEIP. The
final value is a OR of both, so we add two bools and use that to keep
track of the current state. This way either source can change without
losing the correct value.

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.

The next several commits copy some code from qemu.qmp to qemu.aqmp, then
delete qemu.qmp. In the interim, to prevent test failures, the duplicate
code detection needs to be silenced to prevent bisect problems with CI
testing.

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.

Therefore, I am asking permission from the current authors of this

- 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.

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+.

The legacy.py module is heavily based on the QMP module by Luiz
Capitulino (et al) which is licensed as explicit GPLv2-only. The async
QMP package is currently licensed similarly, but I intend to relicense
the async package to the more flexible LGPLv2+.
In preparation for that change, make the license on legacy.py explicit.

[Fixed minor rebase conflict. --js]
Signed-off-by: John Snow <jsnow@redhat.com>
We don't have to maintain compatibility with both QMP libraries anymore,
so we can just remove the old exception. While we're here, take
advantage of the extra fields present in the VMLaunchFailure exception
that machine.py now raises.
(Note: I'm leaving the logging suppression here unchanged. I had
suggested previously we use filters to scrub the PID out of the logging
information so it could just be diffed as part of the iotest output, but
that meant *always* scrubbing PID from logger output, which defeated the
point of even offering that information in the output to begin with.
Ultimately, I decided it's fine to just suppress the logger temporarily.)
