is only set if dsound is in use, so use CONFIG_AUDIO_DSOUND directly.

monitor: Tidy up find_device_state()

Commit 6287d827d4 "monitor: allow device_del to accept QOM paths"
extended find_device_state() to accept QOM paths in addition to qdev
IDs.  This added a checked conversion to TYPE_DEVICE at the end, which
duplicates the check done for the qdev ID case earlier, except it sets
a *different* error: GenericError "ID is not a hotpluggable device"
when passed a QOM path, and DeviceNotFound "Device 'ID' not found"
when passed a qdev ID.  Fortunately, the latter won't happen as long
as we add only devices to /machine/peripheral/.

Earlier, commit b6cc36abb2 "qdev: device_del: Search for to be
unplugged device in 'peripheral' container" rewrote the lookup by qdev
ID to use QOM instead of qdev_find_recursive(), so it can handle
buss-less devices.  It does so by constructing an absolute QOM path.
Works, but object_resolve_path_component() is easier.  Switching to it
also gets rid of the unclean duplication described above.

While there, avoid converting to TYPE_DEVICE twice, first to check
whether it's possible, and then for real.

3 years agopython/qmp: clear events on get_events() call
John Snow [Thu, 23 Sep 2021 00:49:29 +0000 (20:49 -0400)]
python/qmp: clear events on get_events() call

All callers in the tree *already* clear the events after a call to
get_events(). Do it automatically instead and update callsites to remove
the manual clear call.

These semantics are quite a bit easier to emulate with async QMP, and
nobody appears to be abusing some emergent properties of what happens if
you decide not to clear them, so let's dial down to the dumber, simpler
thing.

Specifically: callers of clear() right after a call to get_events() are
more likely expressing their desire to not see any events they just
retrieved, whereas callers of clear_events() not in relation to a recent
call to pull_event/get_events are likely expressing their desire to
simply drop *all* pending events straight onto the floor. In the sync
world, this is safe enough; in the async world it's nearly impossible to
promise that nothing happens between getting and clearing the
events.

Making the retrieval also clear the queue is vastly simpler.

3 years agopython/aqmp: Disable logging messages by default
John Snow [Thu, 23 Sep 2021 00:49:28 +0000 (20:49 -0400)]
python/aqmp: Disable logging messages by default

AQMP is a library, and ideally it should not print error diagnostics
unless a user opts into seeing them. By default, Python will print all
WARNING, ERROR or CRITICAL messages to screen if no logging
configuration has been created by a client application.

In AQMP's case, ERROR logging statements are used to report additional
detail about runtime failures that will also eventually be reported to the
client library via an Exception, so these messages should not be
rendered by default.

(Why bother to have them at all, then? In async contexts, there may be
multiple Exceptions and we are only able to report one of them back to
the client application. It is not reasonably easy to predict ahead of
time if one or more of these Exceptions will be squelched. Therefore,
it's useful to log intermediate failures to help make sense of the
ultimate, resulting failure.)

Add a NullHandler that will suppress these messages until a client
application opts into logging via logging.basicConfig or similar. Note
that upon calling basicConfig(), this handler will *not* suppress these
messages from being displayed by the client's configuration.

python/aqmp: add send_fd_scm

Add an implementation for send_fd_scm to the async QMP implementation.
Like socket_scm_helper mentions, a non-empty payload is required for
QEMU to process the ancillary data. A space is most useful because it
does not disturb the parsing of subsequent JSON objects.

A note on "voiding the warranty":

Python 3.11 removes support for calling sendmsg directly from a
transport's socket. There is no other interface for doing this, our use
case is, I suspect, "quite unique".

As far as I can tell, this is safe to do -- send_fd_scm is a synchronous
function and we can be guaranteed that the async coroutines will *not* be
running when it is invoked. In testing, it works correctly.

I investigated quite thoroughly the possibility of creating my own
asyncio Transport (The class that ultimately manages the raw socket
object) so that I could manage the socket myself, but this is so wildly
invasive and unportable I scrapped the idea. It would involve a lot of
copy-pasting of various python utilities and classes just to re-create
the same infrastructure, and for extremely little benefit. Nah.

Just boldly void the warranty instead, while I try to follow up on

accel/tcg: re-factor plugin_inject_cb so we can assert insn_idx is valid

Coverity doesn't know enough about how we have arranged our plugin TCG
ops to know we will always have incremented insn_idx before injecting
the callback. Let us assert it for the benefit of Coverity and protect
ourselves from accidentally breaking the assumption and triggering
harder to grok errors deeper in the code if we attempt a negative
indexed array lookup.

However to get to this point we re-factor the code and remove the
second hand instruction boundary detection in favour of scanning the
full set of ops and using the existing INDEX_op_insn_start to cleanly
detect when the instruction has started. As we no longer need the
plugin specific list of ops we delete that.

My initial benchmarks shows no discernible impact of dropping the
plugin specific ops list.

hw: aspeed_gpio: Fix GPIO array indexing

This can result in an out-of-bounds access to "s->gpios" because the
gpio sets do _not_ have the same length. Some of the groups (e.g.
GPIOAB) only have 4 pins. 228 != 8 * 32 == 256.

To fix this, I converted the gpio array from dense to sparse, to that
match both the hardware layout and this existing indexing code.
