hw/smbios: support for type 41 (onboard devices extended information)
Type 41 defines the attributes of devices that are onboard. The
original intent was to imply the BIOS had some level of control over
the enablement of the associated devices.
If network devices are present in this table, by default, udev will
name the corresponding interfaces enoX, X being the instance number.
Without such information, udev will fallback to using the PCI ID and
this usually gives ens3 or ens4. This can be a bit annoying as the
name of the network card may depend on the order of options and may
change if a new PCI device is added earlier on the commande line.
Being able to provide SMBIOS type 41 entry ensure the name of the
interface won't change and helps the user guess the right name without
booting a first time.
This can be invoked with:
$QEMU -netdev user,id=internet
-device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \
-smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev
The PCI segment is assumed to be 0. This should hold true for most
cases.
$ dmidecode -t 41
# dmidecode 3.3
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.

Host notifiers are guaranteed to be idle until the callbacks are
hooked up with virtio_queue_aio_set_host_notifier_handler(). They
thus don't need to be set or unset with the AioContext lock held.
Do this outside the critical section, like virtio-blk already
does : basically downgrading virtio_scsi_vring_init() to only
setup the host notifier and set the callback in the caller.
This will allow to batch addition/deletion of ioeventds in

virtio-blk: Fix rollback path in virtio_blk_data_plane_start()
When dataplane multiqueue support was added in QEMU 2.7, the path
that would rollback guest notifiers assignment in case of error
simply got dropped.
Later on, when Error was added to blk_set_aio_context() in QEMU 4.1,
another error path was introduced, but it ommits to rollback both
host and guest notifiers.
It seems cleaner to fix the rollback path in one go. The patch is
simple enough that it can be adjusted if backported to a pre-4.1

qemu-iotests: allow passing unittest.main arguments to the test scripts
Python test scripts that use unittest consist of multiple tests.
unittest.main allows selecting which tests to run, but currently this
is not possible because the iotests wrapper ignores sys.argv.
unittest.main command line options also allow the user to pick the
desired options for verbosity, failfast mode, etc. While "-d" is
currently translated to "-v", it also enables extra debug output,
and other options are not available at all.
These command line options only work if the unittest.main testRunner
argument is a type, rather than a TestRunner instance. Therefore, pass
the class name and "verbosity" argument to unittest.main, and adjust for
the different default warnings between TextTestRunner and unittest.main.

EPERM The mutex type is PTHREAD_MUTEX_ERRORCHECK or

So, thread doesn't own the mutex. And we have iothread here.
Next, note that AIO_WAIT_WHILE() documents that ctx must be acquired
exactly once by caller. But where is it acquired in the call stack?
Seems nowhere.
qemuio_command do acquire aio context.. But we need context acquired
around blk_unref() as well and actually around blk_insert_bs() too.
Let's refactor qemuio_command so that it doesn't acquire aio context
but callers do that instead. This way we can cleanly acquire aio
context in hmp_qemu_io() around all three calls.

block/rbd: Add an escape-aware strchr helper
Sometimes the parser needs to further split a token it has collected
from the token input stream. Right now, it does a cursory check to see
if the relevant characters appear in the token to determine if it should
break it down further.
However, qemu_rbd_next_tok() will escape characters as it removes tokens
from the token stream and plain strchr() won't. This can make the
initial strchr() check slightly misleading since it implies
qemu_rbd_next_tok() will find the token and split on it, except the
reality is that qemu_rbd_next_tok() will pass over it if it is escaped.
Use a custom strchr to avoid mixing escaped and unescaped string
operations. Furthermore, this code is identical to how
qemu_rbd_next_tok() seeks its next token, so incorporate this custom
strchr into the body of that function to reduce duplication.

will return a non-NULL value, and we assume this when we
pass s to qtest_irq_intercept_in(). So we can drop the

tests/qtest/npcm7xx_pwm-test.c: Avoid g_assert_true() for non-test assertions
In the glib API, the distinction between g_assert() and
g_assert_true() is that the former is for "bug, terminate the
application" and the latter is for "test check, on failure either
terminate or just mark the testcase as failed". For QEMU, g_assert()
is always fatal, so code can assume that if the assertion fails
execution does not proceed, but this is not true of g_assert_true().
In npcm7xx_pwm-test, the pwm_index() and pwm_module_index() functions
include some assertions that are just guarding against possible bugs
in the test code that might lead us to out-of-bounds array accesses.
These should use g_assert() because they aren't part of what the test
is testing and the code does not correctly handle the case where the
condition was false.
This fixes some Coverity issues where Coverity knows that
g_assert_true() can continue when the condition is false and
complains about the possible array overrun at various callsites.

libqtest: refuse QTEST_QEMU_BINARY=qemu-kvm
Some downstreams rename the QEMU binary to "qemu-kvm". This breaks
qtest_get_arch(), which attempts to parse the target architecture from

Print an error instead of returning the architecture "kvm". Things fail
in weird ways when the architecture string is bogus.
Arguably qtests should always be run in a build directory instead of
against an installed QEMU. In any case, printing a clear error when this
happens is helpful.
Since this is an error that is triggered by the user and not a test
failure, use exit(1) instead of abort(). Change the existing abort()

migration/ram: Reduce unnecessary rate limiting
When the host page is a huge page and something is sent in the

migrate/ram: remove "ram_bulk_stage" and "fpo_enabled"
The bulk stage is kind of weird: migration_bitmap_find_dirty() will
indicate a dirty page, however, ram_save_host_page() will never save it, as
migration_bitmap_clear_dirty() detects that it is not dirty.
We already fill the bitmap in ram_list_init_bitmaps() with ones, marking
everything dirty - it didn't used to be that way, which is why we needed
an explicit first bulk stage.
Let's simplify: make the bitmap the single source of thuth. Explicitly
handle the "xbzrle_enabled after first round" case.
Regarding XBZRLE (implicitly handled via "ram_bulk_stage = false" right
now), there is now a slight change in behavior:
- Colo: When starting, it will be disabled (was implicitly enabled)
until the first round actually finishes.
- Free page hinting: When starting, XBZRLE will be disabled (was implicitly
enabled) until the first round actually finished.
- Snapshots: When starting, XBZRLE will be disabled. We essentially only
do a single run, so I guess it will never actually get disabled.
Postcopy seems to indirectly disable it in ram_save_page(), so there
shouldn't be really any change.

monitor/qmp: fix race on CHR_EVENT_CLOSED without OOB
The QMP dispatcher coroutine holds the qmp_queue_lock over a yield
point, where it expects to be rescheduled from the main context. If a
CHR_EVENT_CLOSED event is received just then, it can race and block the
main thread on the mutex in monitor_qmp_cleanup_queue_and_resume.
monitor_resume does not need to be called from main context, so we can
call it immediately after popping a request from the queue, which allows
us to drop the qmp_queue_lock mutex before yielding.

Meson 0.58.0 notices that something is iffy, as the dbus_vmstate1

target/riscv: Consolidate RV32/64 16-bit instructions
This patch removes the insn16-32.decode and insn16-64.decode decode
files and consolidates the instructions into the general RISC-V
insn16.decode decode tree.
This means that all of the instructions are avaliable in both the 32-bit
and 64-bit builds. This also means that we run a check to ensure we are
running a 64-bit softmmu before we execute the 64-bit only instructions.
This allows us to include the 32-bit instructions in the 64-bit build,
while also ensuring that 32-bit only software can not execute the
instructions.
