This MemoryRegion is simple enough to be moved in a single step.
A 'stack->phb' pointer had to be introduced in pnv_pec_stk_update_map()
because this function isn't ready to be fully converted to use a PnvPHB4
pointer instead. This will be dealt with in the following patches.

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.

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.

This breaks migration compatibility from (very) old versions of
QEMU. This should not be a problem for the pseries machine for which
migration is only supported on recent QEMUs ( > 2.x). There is no
clear status on what is supported or not for the other machines. Let's
move forward and remove the .load_state_old handler.

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.

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.

This demonstrates what happens when the block status changes in
sub-min_sparse granularity, but all of the parts are zeroed out. The
alignment logic in is_allocated_sectors() prevents that the target image
remains fully sparse as expected, but turns it into a data cluster of
explicit zeros.

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
that vvfat_write() doesn't try to find mappings for negative cluster
number. It clarifies the code in vvfat_write() to make it more obvious
that the cluster numbers can be negative.

With CAP_DAC_OVERRIDE (which e.g. root generally has), permission checks
will be bypassed when opening files.
308 in one instance tries to open a read-only file (FUSE export) with
qemu-io as read/write, and expects this to fail. However, when running
it as root, opening will succeed (thanks to CAP_DAC_OVERRIDE) and only
the actual write operation will fail.
Note this as "Case not run", but have the test pass in either case.

Test the following scenario:
- Simple stream block in two-layer backing chain (base and top)
- The job is drained via blk_drain(), then an error occurs while the job
settles the ongoing request
- And so the job completes while in blk_drain()
This was reported as a segfault, but is fixed by "block-backend: prevent

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().

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.

This code seems to be used by vmport hack, passing these values allows
to implement horizontal scroll support even when using vmport.
In case it's not supported horizontal scroll will act as a vertical one.

This change adds support for horizontal scroll to ps/2 mouse device
code. The code is implemented to match the logic of linux kernel

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.
