Previous patch changed pnv_pec_stk_pci_xscom_read() and
pnv_pec_stk_pci_xscom_write() to use a PnvPHB4 opaque, making it easier
to move both pci_regs[] and the pci_regs_mr MemoryRegion to the PnvHB4
object.

ppc/pnv: use PHB4 obj in pnv_pec_stk_pci_xscom_ops
The current relationship between PnvPhb4PecStack and PnvPHB4 objects is
overly complex. Recent work done in pnv_phb4.c and pnv_phb4_pec.c shows
that the stack obj role in the overall design is more of a placeholder for
its 'phb' object, having no atributes that stand on its own. This became
clearer after pnv-phb4 user creatable devices were implemented.
What remains now are a lot of stack->phb and phb->stack pointers
throughout .read and .write callbacks of MemoryRegionOps that are being
initialized in phb4_realize() time. stk_realize() is a no-op if the
machine is being run with -nodefaults.
The first step of trying to decouple the stack and phb relationship is
to move the MemoryRegionOps that belongs to PnvPhb4PecStack to PhbPHB4.
Unfortunately this can't be done without some preliminary steps to
change the usage of 'stack' and replace it with 'phb' in these
read/write callbacks.
This patch starts this process by using a PnvPHB4 opaque in
pnv_pec_stk_pci_xscom_ops instead of PnvPhb4PecStack.

hw/dma: Let dma_buf_read() / dma_buf_write() propagate MemTxResult

Do not discard it, return it to the caller. Pass the previously

With this new API, SCSIRequest::residual might now be accessed via
a pointer. Since the size_t type does not have the same size on
32 and 64-bit host architectures, convert it to a uint64_t, which
is big enough to hold the residual size, and the type is constant
on both 32/64-bit hosts.

Similarly about how the FlatView are sorted using a GHashTable,
sort the AddressSpace objects to remove the duplications (AS

preserves the initial value, however, it's supposed zero it out

Fix by merging sh32 and sh64 and adapting CC calculation to shift
values greater than 31.
An overflow occurs for SLAG when at least one shifted bit is not equal
to sign bit. Therefore, we need to check that `shift + 1` bits are
neither all 0s nor all 1s. The current code checks only `shift` bits,

A lot of Optional[] types doesn't make code beautiful.
test_field_width defaults to 8, but that is never used in the code.
More over, if we want some default behavior for single call of
test_run(), it should just print the whole test name, not limiting or
expanding its width, so 8 is bad default.
So, just drop the default as unused for now.

First, this permission never protected a node from being changed, as
generic child-replacing functions don't check it.
Second, it's a strange thing: it presents a permission of parent node
to change its child. But generally, children are replaced by different
mechanisms, like jobs or qmp commands, not by nodes.
Graph-mod permission is hard to understand. All other permissions
describe operations which done by parent node on its child: read,
write, resize. Graph modification operations are something completely
different.
The only place where BLK_PERM_GRAPH_MOD is used as "perm" (not shared
perm) is mirror_start_job, for s->target. Still modern code should use
bdrv_freeze_backing_chain() to protect from graph modification, if we
don't do it somewhere it may be considered as a bug. So, it's a bit
risky to drop GRAPH_MOD, and analyzing of possible loss of protection
is hard. But one day we should do it, let's do it now.
One more bit of information is that locking the corresponding byte in
file-posix doesn't make sense at all.

qemu-img: make is_allocated_sectors() more efficient
Consider the case when the whole buffer is zero and end is unaligned.
If i <= tail, we return 1 and do one unaligned WRITE, RMW happens.
If i > tail, we do on aligned WRITE_ZERO (or skip if target is zeroed)
and again one unaligned WRITE, RMW happens.
Let's do better: don't fragment the whole-zero buffer and report it as
ZERO: in case of zeroed target we just do nothing and avoid RMW. If
target is not zeroes, one unaligned WRITE_ZERO should not be much worse
than one unaligned WRITE.

vvfat: Fix vvfat_write() for writes before the root directory
The calculation in sector2cluster() is done relative to the offset of
the root directory. Any writes to blocks before the start of the root
directory (in particular, writes to the FAT) result in negative values,
which are not handled correctly in vvfat_write().
This changes sector2cluster() to return a signed value, and makes sure

number. It clarifies the code in vvfat_write() to make it more obvious
that the cluster numbers can be negative.

block-backend: prevent dangling BDS pointers across aio_poll()
The BlockBackend root child can change when aio_poll() is invoked. This
happens when a temporary filter node is removed upon blockjob
completion, for example.
Functions in block/block-backend.c must be aware of this when using a
blk_bs() pointer across aio_poll() because the BlockDriverState refcnt
may reach 0, resulting in a stale pointer.
One example is scsi_device_purge_requests(), which calls blk_drain() to
wait for in-flight requests to cancel. If the backup blockjob is active,
then the BlockBackend root child is a temporary filter BDS owned by the
blockjob. The blockjob can complete during bdrv_drained_begin() and the
last reference to the BDS is released when the temporary filter node is
removed. This results in a use-after-free when blk_drain() calls
bdrv_drained_end(bs) on the dangling pointer.
Explicitly hold a reference to bs across block APIs that invoke
aio_poll().

softmmu: fix device deletion events with -device JSON syntax
The -device JSON syntax impl leaks a reference on the created
DeviceState instance. As a result when you hot-unplug the
device, the device_finalize method won't be called and thus
it will fail to emit the required DEVICE_DELETED event.
A 'json-cli' feature was previously added against the
'device_add' QMP command QAPI schema to indicated to mgmt
apps that -device supported JSON syntax. Given the hotplug
bug that feature flag is not usable for its purpose, so
we add a new 'json-cli-hotplug' feature to indicate the
-device supports JSON without breaking hotplug.

edid: Added support for 4k@60 Hz monitor
Previously, the large modes (>1080p) that were generated by Qemu in its EDID
were all 50 Hz. If we provide them to a Guest OS and the user selects
one of these modes, then the OS by default only gets 50 FPS. This is
especially true for Windows OS. With this patch, we are now exposing a
3840x2160@60 Hz which will allow the guest OS to get 60 FPS.
Currently QEMU defaults to a resolution of 1024x768 when exposing EDID
info to the guest OS. The EDID default info is important as this will
influence what resolution many guest OS will configure the screen with
on boot. It can also potentially influence what resolution the firmware
will configure the screen with, though until very recently EDK2 would
not handle EDID info.
One important thing to bear in mind is that the default graphics card
driver provided by Windows will leave the display set to whatever
resolution was enabled by the firmware on boot. Even if sufficient
VRAM is available, the resolution can't be changed without installing
new drivers. IOW, the default resolution choice is quite important
for usability of Windows.
Modern real world monitor hardware for desktop/laptop has supported
resolutions higher than 1024x768 for a long time now, perhaps as long
as 15+ years. There are quite a wide variety of native resolutions in
use today, however, and in wide screen form factors the height may not
be all that tall.
None the less, it is considered that there is scope for making the
QEMU default resolution slightly larger.
In considering what possible new default could be suitable, choices
considered were 1280x720 (720p), 1280x800 (WXGA) and 1280x1024 (SXGA).
In many ways, vertical space is the most important, and so 720p was
discarded due to loosing vertical space, despite being 25% wider.
The SXGA resolution would be good, but when taking into account
window titlebars/toolbars and window manager desktop UI, this might
be a little too tall for some users to fit the guest on their physical
montior.
This patch thus suggests a modest change to 1280x800 (WXGA). This
only consumes 1 MB per colour channel, allowing double buffered
framebuffer in 8 MB of VRAM. Width wise this is 25% larger than
QEMU's current default, but height wise this only adds 5%, so the
difference isn't massive on the QEMU side.
Overall there doesn't appear to be a compelling reason to stick
with 1024x768 resolution.

On Windows the jack_set_thread_creator() function and on MacOS the

not available. Use #ifdefs to remove the jack_set_thread_creator()
function call and the qjack_thread_creator() function in both

The qjack_thread_creator() function just sets the name of the

From the call trace, we can see it is a deadlock bug.
vnc_disconnect_finish will acquire the output_mutex.
But, the output_mutex will be acquired again in vnc_clipboard_send.
Repeated locking will cause deadlock. So, I move
qemu_clipboard_peer_unregister() behind vnc_unlock_output();

The virtqueue host notifier API
virtio_queue_aio_set_host_notifier_handler() polls the virtqueue for new
buffers. AioContext previously required a bool progress return value
indicating whether an event was handled or not. This is no longer
necessary because the AioContext polling API has been split into a poll
check function and an event handler function. The event handler is only
run when we know there is work to do, so it doesn't return bool.
The VirtIOHandleAIOOutput function signature is now the same as
VirtIOHandleOutput. Get rid of the bool return value.
Further simplifications will be made for virtio-blk and virtio-scsi in
the next patch.

aio-posix: split poll check from ready handler
Adaptive polling measures the execution time of the polling check plus
handlers called when a polled event becomes ready. Handlers can take a
significant amount of time, making it look like polling was running for
a long time when in fact the event handler was running for a long time.
For example, on Linux the io_submit(2) syscall invoked when a virtio-blk
device's virtqueue becomes ready can take 10s of microseconds. This
can exceed the default polling interval (32 microseconds) and cause
adaptive polling to stop polling.
By excluding the handler's execution time from the polling check we make
the adaptive polling calculation more accurate. As a result, the event
loop now stays in polling mode where previously it would have fallen
back to file descriptor monitoring.
The following data was collected with virtio-blk num-queues=2
event_idx=off using an IOThread. Before:
Notice that ppoll(2) and eventfd read(2) syscalls are eliminated because
the IOThread stays in polling mode instead of falling back to file
descriptor monitoring.
As usual, polling is not implemented on Windows so this patch ignores
the new io_poll_read() callback in aio-win32.c.
