The preferred style is SetupData as a typedef, not setup_data as a plain
struct.

If setup_data is being read into a specific memory location, then
generally the setup_data address parameter is read first, so that the
caller knows where to read it into. In that case, we should return
setup_data containing the absolute addresses that are hard coded and
determined a priori. This is the case when kernels are loaded by BIOS,
for example. In contrast, when setup_data is read as a file, then we
shouldn't modify setup_data, since the absolute address will be wrong by
definition. This is the case when OVMF loads the image.
This allows setup_data to be used like normal, without crashing when EFI
tries to use it.
(As a small development note, strangely, fw_cfg_add_file_callback() was
exported but fw_cfg_add_bytes_callback() wasn't, so this makes that
consistent.)

CHS-based disk utilities and operating systems may adjust the logical
geometry of a hard drive to cope with the expectations or limitations
of software using the ATA INITIALIZE_DEVICE_PARAMETERS command.
Prior to this patch, INITIALIZE_DEVICE_PARAMETERS was a nop that
always returned success, raising the possibility of data loss or
corruption if the CHS<->LBA translation redirected a write to the
wrong sector.
* hw/ide/core.c
ide_reset():
Reset the logical CHS geometry of the hard disk when the power-on
defaults feature is enabled.
cmd_specify():
a) New function implementing INITIALIZE_DEVICE_PARAMETERS.
b) Ignore calls for empty or ATAPI devices.
cmd_set_features():
Implement the power-on defaults enable and disable features.
struct ide_cmd_table:
Switch WIN_SPECIFY from cmd_nop() to cmd_specify().
ide_init_drive():
Set new fields 'drive_heads' and 'drive_sectors' based upon the
actual disk geometry.
* include/hw/ide/internal.h
struct IDEState:
a) Store the actual drive CHS values within the new fields
'drive_heads' and 'drive_sectors.'
b) Track whether a soft IDE reset should also reset the logical CHS
geometry of the hard disk within the new field 'reset_reverts'.

Prior to this patch, cmd_exec_dev_diagnostic relied upon
ide_set_signature to clear the device register. While the
preservation of the drive bit by ide_set_signature is necessary for
the DEVICE RESET, IDENTIFY DEVICE, and READ SECTOR commands,
ATA/ATAPI-6 specifies that "DEV shall be cleared to zero" for EXECUTE
DEVICE DIAGNOSTIC.
This deviation was uncovered by the ATACT Device Testing Program
written by Hale Landis.

Just like qcow2, qed invokes its open function in its
.bdrv_co_invalidate_cache() implementation. Therefore, just like done
for qcow2 in HEAD^, update auto_backing_file only if the backing file
string in the image header differs from the one we have read before.

qcow2_do_open() is used by qcow2_co_invalidate_cache(), i.e. may be run
on an image that has been opened before. When reading the backing file
string from the image header, compare it against the existing
bs->backing_file, and update bs->auto_backing_file only if they differ.
auto_backing_file should ideally contain the filename the backing BDS
will actually have after opening, i.e. a post-bdrv_refresh_filename()
version of what is in the image header. So for example, if the image
header reports the following backing file string:
json:{"driver": "qcow2", "file": {
"driver": "file", "filename": "/tmp/backing.qcow2"
}}
Then auto_backing_file should contain simply "/tmp/backing.qcow2".
Because bdrv_refresh_filename() only works on existing BDSs, though, the
way how we get this auto_backing_file value is to have the format driver
set it to whatever is in the image header, and when the backing BDS is
opened based on that, we update it with the filename the backing BDS
actually got.
However, qcow2's qcow2_co_invalidate_cache() implementation breaks this
because it just resets auto_backing_file to whatever is in the image
file without opening a BDS based on it, so we never get
auto_backing_file back to the "refreshed" version, and in the example
above, it would stay "json:{...}".
Then, bs->backing->bs->filename will differ from bs->auto_backing_file,
making bdrv_backing_overridden(bs) return true, which will lead
bdrv_refresh_filename(bs) to generate a json:{} filename for bs, even
though that may not have been necessary. This is reported in the issue
linked below.
Therefore, skip updating auto_backing_file if nothing has changed in the
image header since we last read it.

The gluster protocol driver used to parse URIs (filenames) but was
extended with a richer JSON syntax in commit 6c7189bb29de
("block/gluster: add support for multiple gluster servers"). The gluster
drivers that have JSON parsing set .bdrv_needs_filename to false.
The gluster+unix and gluster+rdma drivers still to require a filename
even though the JSON parser is equipped to parse the same
volume/path/sockaddr details as the URI parser. Let's allow JSON parsing
for these drivers too.
Note that the gluster+rdma driver actually uses TCP because RDMA support
is not available, so the JSON server.type field must be "inet".
Drop .bdrv_needs_filename since both the filename and the JSON parsers
can handle gluster+unix and gluster+rdma. This change is in preparation
for eventually removing .bdrv_needs_filename across the entire codebase.

Commit 5f76a7aac156ca75680dad5df4a385fd0b58f6b1 is looking harmless from
the first glance, but it has changed things a lot. 'libvirt' uses it to
detect that it should follow new initialization way and this changes
things considerably. With this procedure followed, blockdev_init() is
not called anymore and thus block_acct_setup() helper is not called.
This means in particular that defaults for block accounting statistics
are changed and account_invalid/account_failed are actually initialized
as false instead of true originally.
This commit changes things to match original world. There are the following
constraints:
* new default value in block_acct_init() is set to true
* block_acct_setup() inside blockdev_init() is called before
blkconf_apply_backend_options()
* thus newly created option in block device properties has precedence if
specified

Commit d1258dd0c8 ("qcow2: autoloading dirty bitmaps") added the
set_readonly_helper() GFunc handler, correctly casting the gpointer
user_data in both the g_slist_foreach() caller and the handler.
Few commits later (commit 1b6b0562db), the handler is reused in
qcow2_reopen_bitmaps_rw() but missing the gpointer cast, resulting
in the following error when using Homebrew GCC 12.2.0:

The "msi-parent" property can be used on the PCI node when MSIs do not
contain sideband data (device IDs) [1]. In QEMU, MSI transactions
contain the requester ID, so the PCI node should use the "msi-map"
property instead of "msi-parent". In our case the property describes an
identity map between requester ID and sideband data.
This fixes a warning when passing the DTB generated by QEMU to dtc,
following a recent change to the GICv3 node:

Use the same name for model as for compatible. The specification

cpu64.c has ended up in a slightly odd order -- it starts with the
initfns for most of the models-real-hardware CPUs; after that comes a
bunch of support code for SVE, SME, pauth and LPA2 properties. Then
come the initfns for the 'host' and 'max' CPU types, and then after
that one more models-real-hardware CPU initfn, for a64fx. (This
ordering is partly historical and partly required because a64fx needs
the SVE properties.)
Reorder the file into:
* CPU property support functions
* initfns for real hardware CPUs
* initfns for host and max
* class boilerplate

Our SDCR_VALID_MASK doesn't include all of the bits which are defined
by the current architecture. In particular in commit 0b42f4fab9d3 we
forgot to add SCCD, which meant that an AArch32 guest couldn't
actually use the SCCD bit to disable counting in Secure state.
Add all the currently defined bits; we don't implement all of them,
but this makes them be reads-as-written, which is architecturally
valid and matches how we currently handle most of the others in the
mask.

In commit 01765386a88868 we fixed a bug where we weren't correctly
bracketing changes to some registers with pmu_op_start() and
pmu_op_finish() calls for changes which affect whether the PMU
counters might be enabled. However, we missed the case of writes to
the AArch64 MDCR_EL3 register, because (unlike its AArch32
counterpart) they are currently done directly to the CPU state struct
without going through the sdcr_write() function.
Give MDCR_EL3 a writefn which handles the PMU start/finish calls.
The SDCR writefn then simplfies to "call the MDCR_EL3 writefn after
masking off the bits which don't exist in the AArch32 register".

In commit 01765386a888 we made some system register write functions
call pmu_op_start()/pmu_op_finish(). This means that they now touch
timers, so for icount to work these registers must have the ARM_CP_IO
flag set.
This fixes a bug where when icount is enabled a guest that touches
MDCR_EL3, MDCR_EL2, PMCNTENSET_EL0 or PMCNTENCLR_EL0 would cause
QEMU to print an error message and exit, for example:

As the close-on-exec flags is not set on the file descriptors returned
by socketpair() at default, the fds will survive across exec' function.
In the case that exec' function get invoked, such as the live-update feature
which is been developing, it will cause fd leaks.
To address this problem, we should call qemu_socketpair() to create an pair of
connected sockets with the close-on-exec flag set.

If finalize chardev-msmouse or chardev-wctable is called immediately after
init it cases QEMU to crash with segfault. This happens because of
QTAILQ_REMOVE in qemu_input_handler_unregister tries to dereference

Unaligned i/o access on serial UART works on real PCs.
This is used for example by FreeDOS CTMouse driver. Without this it
can't reset and detect serial mice.

Make use of fifo8 functions instead of implementing own fifo code.
This makes the code more readable and reduces risk of bugs.

This allows using buffers returned by fifo as buf parameter and source buffer

Detect mouse reset via RTS or DTR line:
Don't send or process anything while in reset.
When coming out of reset, send ID sequence first thing.
This allows msmouse to be detected by common mouse drivers.

This qtest executable created a serial chardev file to be passed to
the QEMU executable. The serial file was created by g_file_open_tmp(),
which internally opens the file with FILE_SHARE_WRITE security attribute
on Windows. Based on [1], there is only one case that allows the first
call to CreateFile() with GENERIC_READ & FILE_SHARE_WRITE, and second
call to CreateFile() with GENERIC_WRITE & FILE_SHARE_READ. All other
combinations require FILE_SHARE_WRITE in the second call. But there is
no way for the second call (in this case the QEMU executable) to know
what combination was passed to the first call, unless FILE_SHARE_WRITE
is passed to the second call.
Two processes shouldn't share the same file for writing with a chardev.
Let's close the serial file before starting QEMU.
