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.

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.

tests/docker: promote debian-riscv64-cross to a full image
To be able to cross build QEMU itself we need to include a few more
libraries. These are only available in Debian's unstable ports repo
for now so we need to base the riscv64 image on sid with the the
minimal libs needed to build QEMU (glib/pixman).
The result works but is not as clean as using build-dep to bring in
more dependencies. However sid is by definition a shifting pile of
sand and by keeping the list of libs minimal we reduce the chance of
having an image we can't build. It's good enough for a basic cross

aspeed/smc: Add watchdog Control/Status Registers
The Aspeed SoCs have a dual boot function for firmware fail-over
recovery. The system auto-reboots from the second flash if the main
flash does not boot successfully within a certain amount of time. This
function is called alternate boot (ABR) in the FMC controllers.
On AST2400/AST2500, ABR is enabled by hardware strapping in SCU70 to
enable the 2nd watchdog timer, on AST2600, through register SCU510.
If the boot on the the main flash succeeds, the firmware should
disable the 2nd watchdog timer. If not, the BMC is reset and the CE0
and CE1 mappings are swapped to restart the BMC from the 2nd flash.
On the AST2600, the ABR registers controlling the 2nd watchdog timer
were moved from the watchdog register to the FMC controller and the
FMC model should be able to control WDT2 through its own register set.
This requires more work. For now, add dummy read/write handlers to let
the FW disable the 2nd watchdog without error.

The MacOS driver expects a 60.15Hz vertical blank interrupt to be generated by
the framebuffer which in turn schedules the mouse driver via the Vertical Retrace
Manager.
According to Apple Technical Note HW26: "Macintosh Quadra Built-In Video" the
in-built framebuffer encodes each 24-bit pixel into 4 bytes. Adjust the 24-bit
RGB pixel encoding accordingly which agrees with the encoding expected by MacOS
when changing into 24-bit colour mode.
macfb: add common monitor modes supported by the MacOS toolbox ROM
The monitor modes table is found by experimenting with the Monitors Control
Panel in MacOS and analysing the reads/writes. From this it can be found that
the mode is controlled by writes to the DAFB_MODE_CTRL1 and DAFB_MODE_CTRL2
registers.
Implement the first block of DAFB registers as a register array including the
existing sense register, the newly discovered control registers above, and also
the DAFB_MODE_VADDR1 and DAFB_MODE_VADDR2 registers which are used by NetBSD to
determine the current video mode.
These experiments also show that the offset of the start of video RAM and the
stride can change depending upon the monitor mode, so update macfb_draw_graphic()
and both the BI_MAC_VADDR and BI_MAC_VROW bootinfo for the q800 machine
accordingly.
Finally update macfb_common_realize() so that only the resolution and depth
supported by the display type can be specified on the command line, and add an
error hint showing the list of supported resolutions and depths if the user tries
to specify an invalid display mode.
Since the available resolutions and colour depths are determined by the attached
display type, add a qdev property to allow the display type to be specified.
The main resolutions of interest are high resolution 1152x870 with 8-bit colour
and SVGA resolution up to 800x600 with 24-bit colour so update the q800 machine
to allow high resolution mode if specified and otherwise fall back to SVGA.

macfb: implement mode sense to allow display type to be detected
The MacOS toolbox ROM uses the monitor sense to detect the display type and then
offer a fixed set of resolutions and colour depths accordingly. Implement the
monitor sense using information found in Apple Technical Note HW26: "Macintosh
Quadra Built-In Video" along with some local experiments.
Since the default configuration is 640 x 480 with 8-bit colour then hardcode
the sense register to return MACFB_DISPLAY_VGA for now.
macfb: use memory_region_init_ram() in macfb_common_realize() for the framebuffer
Currently macfb_common_realize() defines the framebuffer RAM memory region as
being non-migrateable but then immediately registers it for migration. Replace
memory_region_init_ram_nomigrate() with memory_region_init_ram() which is clearer
and does exactly the same thing.
The palette_current index counter has a maximum size of 256 * 3 to cover a full
color palette of 256 RGB entries. Linux assumes that the palette_current index
wraps back around to zero after writing 256 RGB entries so ensure that
palette_current is reset at this point to prevent data corruption within
MacfbState.
macfb: fix invalid object reference in macfb_common_realize()
During realize memory_region_init_ram_nomigrate() is used to initialise the RAM
memory region used for the framebuffer but the owner object reference is
incorrect since MacFbState is a typedef and not a QOM type.
Change the memory region owner to be the corresponding DeviceState to fix the
issue and prevent random crashes during macfb_common_realize().

iothread: use IOThreadParamInfo in iothread_[set|get]_param()
Commit 0445409d74 ("iothread: generalize
iothread_set_param/iothread_get_param") moved common code to set and
get IOThread parameters in two new functions.
These functions are called inside callbacks, so we don't need to use an
opaque pointer. Let's replace `void *opaque` parameter with
`IOThreadParamInfo *info`.

iothread: rename PollParamInfo to IOThreadParamInfo
Commit 1793ad0247 ("iothread: add aio-max-batch parameter") added
a new parameter (aio-max-batch) to IOThread and used PollParamInfo
structure to handle it.
Since it is not a parameter of the polling mechanism, we rename the
structure to a more generic IOThreadParamInfo.

iotests: Add mirror-ready-cancel-error test
Test what happens when there is an I/O error after a mirror job in the
READY phase has been cancelled.

mirror: Do not clear .cancelled
Clearing .cancelled before leaving the main loop when the job has been
soft-cancelled is no longer necessary since job_is_cancelled() only
returns true for jobs that have been force-cancelled.
Therefore, this only makes a differences in places that call
job_cancel_requested(). In block/mirror.c, this is done only before
.cancelled was cleared.
In job.c, there are two callers:
- job_completed_txn_abort() asserts that .cancelled is true, so keeping
it true will not affect this place.
- job_complete() refuses to let a job complete that has .cancelled set.
It is correct to refuse to let the user invoke job-complete on mirror
jobs that have already been soft-cancelled.
With this change, there are no places that reset .cancelled to false and
so we can be sure that .force_cancel can only be true if .cancelled is
true as well. Assert this in job_is_cancelled().

mirror: Stop active mirroring after force-cancel
Once the mirror job is force-cancelled (job_is_cancelled() is true), we
should not generate new I/O requests. This applies to active mirroring,
too, so stop it once the job is cancelled.
(We must still forward all I/O requests to the source, though, of
course, but those are not really I/O requests generated by the job, so
this is fine.)
