Now that we can properly map sysbus devices that haven't been connected to
something forcefully by C code, we can allow the -device command line option
to spawn them.
For machines that don't implement dynamic sysbus assignment in their board
files we add a new bool "has_dynamic_sysbus" to the machine class.
When that property is false (default), we bail out when we see dynamically
spawned sysbus devices, like we did before.

Differently from older versions, SMBIOS version 2.6 is explicit about
the encoding of UUID fields:

> industry (including the ACPI, UEFI, and Microsoft specifications) has
> consistently used little-endian byte encoding for the first three fields:
> time_low, time_mid, time_hi_and_version. The same encoding, also known as
> wire format, should also be used for the SMBIOS representation of the UUID.
>
> The UUID {00112233-4455-6677-8899-AABBCCDDEEFF} would thus be represented
> as 33 22 11 00 55 44 77 66 88 99 AA BB CC DD EE FF.
The dmidecode tool implements this and decodes the above "wire format"
when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when
we started building the SMBIOS entry point inside QEMU, on commit
c97294ec1b.
Change smbios_build_type_1_table() to encode the UUID as specified.
To make sure we won't change the guest-visible UUID when upgrading to a
newer QEMU version, keep the old behavior on pc-*-2.1 and older.

Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine
list") broke the ordering of the machine types in the user-visible output
of
qemu-system-XXXX -M \?
This occurred because registration was rebased from a manually maintained
linked list to GLib hash tables:
qemu_register_machine()
type_register()
type_register_internal()
type_table_add()
g_hash_table_insert()
and because the listing was rebased accordingly, from the traversal of the
list to the traversal of the hash table (rendered as an ad-hoc list):
machine_parse()
object_class_get_list(TYPE_MACHINE)
object_class_foreach()
g_hash_table_foreach()
The current order is a "random" one, for practical purposes, which is
annoying for users.
Introduce new members QEMUMachine.family and MachineClass.family, allowing
machine types to be "clustered". Introduce a comparator function that
establishes a total ordering between machine types, ordering machine types
in the same family next to each other. In machine_parse(), list the
supported machine types sorted with the comparator function.
The comparator function:
- sorts whole families before standalone machine types,
- sorts whole families between each other in alphabetically increasing
order,
- sorts machine types inside the same family in alphabetically decreasing
order,
- sorts standalone machine types between each other in alphabetically
increasing order.
After this patch, all machine types are considered standalone, and
accordingly, the output is alphabetically ascending. This will be refined
in the following patches.

In case of -daemonize, we write non-zero to the daemon
pipe only if pidfile creation failed, so the parent will
report error about pidfile problem. There's no need to
make special case for this, since all other errors are
reported by the child just fine. Let the parent report
error and simplify logic in os_daemonize().
This way, we don't need os_pidfile_error() function, since
it only prints error now, so put the error reporting printf
into the only place where qemu_create_pidfile() is called,
in vl.c.
While at it, fix wrong indentation in os_daemonize().

commit abfd9ce3(migration: dump vmstate info as a json
file for static analysis) introduce a new command,
'-dump-vmstate', that takes a filename
as an argument. When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.
However, only one instance of the -dump-vmstate option is supported.
If more were given, the vmstate_dump_file variable would be overwritten.
This fix also helps silence a Coverity error.

qemu_shutdown_requested may be interrupted by qemu_system_killed. If the
latter sets shutdown_requested after qemu_shutdown_requested has read it
but before it was cleared, the shutdown event is lost. Fix this by using
atomic_xchg.
This provides a different fix for the problem which commit 15124e142
attempts to deal with. That commit breaks use of ^C to drop into gdb,
and so this approach is better (and 15124e142 can be reverted).

This command lists PCMCIA sockets and cards. Only a few ARM boards
have sockets (akita, borzoi, connex, mainstone, spitz, terrier, tosa,
verdex, z2), the only card is the DSCM-1xxxx Hitachi Microdrive (qdev
"microdrive"), and it is only inserted during machine init, if ever.
So this command doesn't really tell anybody anything new so far.
Moreover, pcmcia_socket_unregister() has a use-after-free bug, flagged
by Coverity. Has never been used, because there has never been code
to eject a PCMCIA card.
Not worth fixing & converting to QMP. Remove it.

allows individual boards to declare their desired
index => (bus,unit) mapping for their default HBA, so that
boards such as Q35 can specify that its default if_ide HBA,
AHCI, only accepts one unit per bus.
This property only overrides the mapping for drives matching
the block_default_type interface.
This patch also adds this property to *all* past and present
Q35 machine types. This retroactive addition is justified
because the previous erroneous index=>(bus,unit) mappings
caused by lack of such a property were not utilized due to
lack of initialization code in the Q35 init routine.
Further, semantically, the Q35 board type has always had the
property that its default HBA, AHCI, only accepts one unit per
bus. The new code added to add devices to drives relies upon
the accuracy of this mapping. Thus, the property is applied
retroactively to reduce complexity of allowing IDE HBAs with
different units per bus.
Examples:
Prior to this patch, all IDE HBAs were assumed to use 2 units
per bus (Master, Slave). When using Q35 and AHCI, however, we
only allow one unit per bus.
-hdb foo.qcow2 would become index=1, or bus=0,unit=1.
-hdd foo.qcow2 would become index=3, or bus=1,unit=1.
-drive file=foo.qcow2,index=5 becomes bus=2,unit=1.
These are invalid for AHCI. They now become, under Q35 only:
-hdb foo.qcow2 --> index=1, bus=1, unit=0.
-hdd foo.qcow2 --> index=3, bus=3, unit=0.
-drive file=foo.qcow2,index=5 --> bus=5,unit=0.
The mapping is adjusted based on the fact that the default IF
for the Q35 machine type is IF_IDE, and units-per-default-bus
overrides the IDE mapping from its default of 2 units per bus
to just 1 unit per bus.

When users use command line options like -hda, -cdrom,
or even -drive if=ide, it is up to the board initialization
routines to pick up these drives and create backing
devices for them.
Some boards, like Q35, have not been doing this.
However, there is no warning explaining why certain
drive specifications are just silently ignored,
so this function adds a check to print some warnings
to assist users in debugging these sorts of issues
in the future.
This patch will not warn about drives added with if_none,
for which it is not possible to tell in advance if
the omission of a backing device is an issue.
A warning in these cases is considered appropriate.

If we configure mlock=on and memory policy=bind at the same time,
It will consume lots of time for system to treat with memory,
especially when call mbind behind mlockall.
Adjust the place of calling mlockall, calling mbind before mlockall
can remarkably reduce the time of VM's startup.

On a system with a low limit of open files the initialization
of the event notifier could fail and QEMU exits without printing any
error information to the user.
The problem can be easily reproduced by enforcing a low limit of open
files and start QEMU with enough I/O threads to hit this limit.
The same problem raises, without the creation of I/O threads, while
QEMU initializes the main event loop by enforcing an even lower limit of
open files.
This commit adds an error message on failure:

2. Accroding to the machine option, q35 will initialize the Intel IOMMU and

the pci bus.
3. q35_host_dma_iommu() will return different address space according to the

We have the experience that the guest doesn't stop successfully
though it was instructed to shut down.
The root cause may be not in QEMU mostly. However, QEMU is often
suspected at the beginning just because the issue occurred in
virtualization environment.
Therefore, we need to affirm that QEMU received the shutdown
request and raised ACPI irq from "virsh shutdown" command,
virt-manger or stopping QEMU process to the VM .
So that we can affirm the problems was belonged to the Guset OS
rather than the QEMU itself.
When we stop guests by "virsh shutdown" command or virt-manger,
or stopping QEMU process, qemu_system_powerdown_request() or
qemu_system_shutdown_request() is called. Then the below functions
in main_loop_should_exit() of Vl.c are called roughly in the
following order.
if (qemu_powerdown_requested())
qemu_system_powerdown()
monitor_protocol_event(QEVENT_POWERDOWN, NULL)
OR
if(qemu_shutdown_requested()}
monitor_protocol_event(QEVENT_SHUTDOWN, NULL);
The tracepoint of monitor_protocol_event() already exists, but no
tracepoints are defined for qemu_system_powerdown_request() and
qemu_system_shutdown_request(). So this patch adds two tracepoints for
the two functions. We believe that it will become much easier to
isolate the problem mentioned above by these tracepoints.

for the machine type it's invoked with to the file, and quit.
The JSON-format output can then be used to compare the vmstate info for
different QEMU versions, specifically to test whether live migration
would break due to changes in the vmstate data.

This is a pc & q35 only machine opt.
If you add enough PCI devices then all mmio for them will not fit
below 4G which may not be the layout the user wanted. This allows
you to increase the below 4G address space that PCI devices can use
(aka decrease ram below 4G) and therefore in more cases not have any
mmio that is above 4G.
For example using "-machine pc,max-ram-below-4g=2G" on the command
line will limit the amount of ram that is below 4G to 2G.
Note: this machine option cannot be used to increase the amount
of ram below 4G.
