c05aa1406b ppc/pnv: Remove PnvLpcController::psi link
Create an anonymous output GPIO line to connect the LPC device with
the PSIHB device and raise the appropriate PSI IRQ line depending on

A temporary __pnv_psi_irq_set() routine is introduced to handle the
transition. It will be removed when all devices raising PSI interrupts
are converted to use GPIOs.

58858759c1 ppc/pnv: Fix PSI IRQ definition
On HW, the PSI and FSP interrupt levels are muxed under the same
interrupt number. For coding reasons, an extra IRQ number was
introduced to index register values in an array. It increased the
count of IRQs which do not fit in the PSI IRQ range anymore.

The PSI and FSP interrupts should be modeled with an extra level of
GPIO lines but since QEMU does not support them, simply drop the extra
number to stay within the IRQ range.

c74824389e tcg: Fix indirect lowering vs TCG_OPF_COND_BRANCH
With TCG_OPF_COND_BRANCH, we extended the lifetimes of
globals across extended basic blocks.  This means that
the liveness computed in pass 1 does not kill globals
in the same way as normal temps.

Introduce TYPE_EBB to match this lifetime, so that we
get correct register allocation for the temps that we
introduce during the indirect lowering pass.

so presumably whatever the issue was, it has been fixed during
the preceeding 18 years.

a83c284490 acpi: fix acpi_index migration
vmstate_acpi_pcihp_use_acpi_index() was expecting AcpiPciHpState
as state but it actually received PIIX4PMState, because
VMSTATE_PCI_HOTPLUG is a macro and not another struct.
So it ended up accessing random pointer, which resulted
in 'false' return value and acpi_index field wasn't ever
sent.

However in 7.0 that pointer de-references to value > 0, and
destination QEMU starts to expect the field which isn't
sent in migratioon stream from older QEMU (6.2 and older).
As result migration fails with:
  qemu-system-x86_64: Missing section footer for 0000:00:01.3/piix4_pm
  qemu-system-x86_64: load of migration failed: Invalid argument

In addition with QEMU-6.2, destination due to not expected
state, also never expects the acpi_index field in migration
stream.

Q35 is not affected as it always sends/expects the field as
long as acpi based PCI hotplug is enabled.

Fix issue by introducing compat knob to never send/expect
acpi_index in migration stream for 6.2 and older PC machine

73d2407407 hyperv: Add support to process syndbg commands
SynDbg commands can come from two different flows:
1. Hypercalls, in this mode the data being sent is fully
   encapsulated network packets.
2. SynDbg specific MSRs, in this mode only the data that needs to be
   transfered is passed.

a0d45db854 thread-posix: implement Semaphore with QemuCond and QemuMutex
Now that QemuSemaphore is implemented through pthread_cond_t only, we can use
QemuCond and QemuMutex to make the code smaller.  Features such as mutex
tracing and CLOCK_MONOTONIC timedwait are supported in qemu-sem naturally.

f9fc8932b1 thread-posix: remove the posix semaphore support
POSIX specifies an absolute time for sem_timedwait(), it would be
affected if the system time is changing, but there is not a relative
time or monotonic clock version of sem_timedwait, so we cannot gain
from POSIX semaphore any more.

An alternative way is to use sem_trywait + usleep, maybe we can
remove CONFIG_SEM_TIMEDWAIT in this way? No, because some systems
(e.g. mac os) mark the sem_xxx API as deprecated.

So maybe remove the usage of POSIX semaphore and turn to use the
pthread variant for all systems looks better.

d7482ffe97 whpx: Added support for breakpoints and stepping
Below is the updated version of the patch adding debugging support to WHPX.
It incorporates feedback from Alex Bennée and Peter Maydell regarding not
changing the emulation logic depending on the gdb connection status.

Instead of checking for an active gdb connection to determine whether QEMU
should intercept the INT1 exceptions, it now checks whether any breakpoints
have been set, or whether gdb has explicitly requested one or more CPUs to
do single-stepping. Having none of these condition present now has the same
effect as not using gdb at all.

b1c0734905 main-loop: Disable GLOBAL_STATE_CODE() assertions
These assertions are very useful for developers to find bugs, and so
they have indeed pointed us towards bugs already.  For users, it is not
so useful to find these bugs.  We should probably not enable them in
releases until we are sufficiently certain that they will not fire
during normal operation, unless something is going seriously wrong.

For example, we have received a bug report that you cannot add an NBD
server on a BDS in an I/O thread with `-incoming defer`.  I am sure this
is a real bug that needs investigation, but we do not really have that
time right now, so close to release, and so I would rather disable the
assertions to get time to investigate such reports.

(I am just putting the link as "buglink" below, not "closes", because
disabling the assertion will not fix the likely underlying bug.)

b21e238037 Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

8900c204df util/osdep: Avoid madvise proto on modern Solaris
On older Solaris releases (before Solaris 11), we didn't get a
prototype for madvise, and so util/osdep.c provides its own prototype.
Some time between the public Solaris 11.4 release and Solaris 11.4.42
CBE, we started getting an madvise prototype that looks like this:

    extern int madvise(void *, size_t, int);

which conflicts with the prototype in util/osdeps.c. Instead of always
declaring this prototype, check if we're missing the madvise()
prototype, and only declare it ourselves if the prototype is missing.
Move the prototype to include/qemu/osdep.h, the normal place to handle
platform-specific header quirks.

The 'missing_madvise_proto' meson check contains an obviously wrong
prototype for madvise. So if that code compiles and links, we must be
missing the actual prototype for madvise.

the cpu_list() function is only defined in target-specific code
in "cpu.h". Move list_cpus() declaration to "exec/cpu-common.h"
because this function is not softmmu-specific and can also be
used by user-mode, along with moving its implementation to cpu.c,
which is compiled per target.

def4c5570c kvm/msi: do explicit commit when adding msi routes
We invoke the kvm_irqchip_commit_routes() for each addition to MSI route
table, which is not efficient if we are adding lots of routes in some cases.

This patch lets callers invoke the kvm_irqchip_commit_routes(), so the
callers can decide how to optimize.

The DBus listener naively create, update and destroy textures without
taking into account other listeners. The texture were shared, but
texture update was unnecessarily duplicated.

Teach DisplayGLCtx to do optionally shared texture handling. This is
only implemented for DBus display at this point, however the same
infrastructure could potentially be used for other future combinations.

12a195fa34 vdpa: Expose VHOST_F_LOG_ALL on SVQ
SVQ is able to log the dirty bits by itself, so let's use it to not
block migration.

Also, ignore set and clear of VHOST_F_LOG_ALL on set_features if SVQ is
enabled. Even if the device supports it, the reports would be nonsense
because SVQ memory is in the qemu region.

The log region is still allocated. Future changes might skip that, but
this series is already long enough.

9c10d86fee ppc/pnv: Remove user-created PHB{3,4,5} devices
On a real system with POWER{8,9,10} processors, PHBs are sub-units of
the processor, they can be deactivated by firmware but not plugged in
or out like a PCI adapter on a slot. Nevertheless, having user-created
PHBs in QEMU seemed to be a good idea for testing purposes :

 1. having a limited set of PHBs speedups boot time.
 2. it is useful to be able to mimic a partially broken topology you
    some time have to deal with during bring-up.

PowerNV is also used for distro install tests and having libvirt
support eases these tasks. libvirt prefers to run the machine with
-nodefaults to be sure not to drag unexpected devices which would need
to be defined in the domain file without being specified on the QEMU
command line. For this reason :

 3. -nodefaults should not include default PHBs

User-created PHB{3,4,5} devices satisfied all these needs but reality
proves to be a bit more complex, internally when modeling such
devices, and externally when dealing with the user interface.

Req 1. and 2. can be simply addressed differently with a machine option:
"phb-mask=<uint>", which QEMU would use to enable/disable PHB device
nodes when creating the device tree.

For Req 3., we need to make sure we are taking the right approach. It
seems that we should expose a new type of user-created PHB device, a
generic virtualized one, that libvirt would use and not one depending
on the processor revision. This needs more thinking.

For now, remove user-created PHB{3,4,5} devices. All the cleanups we
did are not lost and they will be useful for the next steps.

d3df1f6470 ppc/pnv: Introduce a pnv-phb5 device to match root port
We already have the pnv-phb3 and pnv-phb4 devices for POWER8 and
POWER9 respectively. POWER10 uses version 5 of the PHB. It is very
close to the PHB4 from POWER9, at least in our model and we could
almost keep using the PHB4 model. However the matching root port
pnv-phb5-root-port is specific to POWER10 so to avoid confusion as
well as making it easy to introduce differences later, we create a
pnv-phb5 class, which is mostly an alias for pnv-phb4 for now.

With this patch, the command line for a user-created PHB on powernv10
becomes:
  -machine powernv10 -nodefaults -device pnv-phb5 -device pnv-phb5-root-port

dd2a56ab6f macfb: increase number of registers saved in MacfbState
The MacOS toolbox ROM accesses a number of addresses between 0x0 and 0x200 during
initialisation and resolution changes. Whilst the function of many of these
registers is unknown, it is worth the minimal cost of saving these extra values as
part of migration to help future-proof the migration stream for the q800 machine
as it starts to stabilise.

Note this is a migration break, but since there are upcoming incompatible changes
for the q800 machine (and migration does not even succeed without these patches)
then this is not an issue.

b793b4ef8c mos6522: implement edge-triggering for CA1/2 and CB1/2 control line IRQs
The mos6522 datasheet describes how the control lines IRQs are edge-triggered
according to the configuration in the PCR register. Implement the logic according
to the datasheet so that the interrupt bits in IFR are latched when the edge is
detected, and cleared when reading portA/portB or writing to IFR as necessary.

To maintain bisectibility this change also updates the SCSI, SCSI data, Nubus
and VIA2 60Hz/1Hz clocks in the q800 machine to be negative edge-triggered as
confirmed by the PCR programming in all of Linux, NetBSD and MacOS.

Currently the QAPI generators for HumanReadableText don't work correctly if

now manually add a hmp_info_via() wrapper until direct support for per-device

3b004a1654 hw/rtc/mc146818rtc: QOM'ify IRQ number
Exposing the IRQ number as a QOM property not only allows it to be
configurable but also to be displayed in HMP:

Before:

(qemu) info qtree
       ...
          dev: mc146818rtc, id ""
            gpio-out "" 1
            base_year = 0 (0x0)
            lost_tick_policy = "discard"

After:

          dev: mc146818rtc, id ""
            gpio-out "" 1
            base_year = 0 (0x0)
            irq = 8 (0x8)
            lost_tick_policy = "discard"

The reason the IRQ number didn's show up before is that this device does not
call isa_init_irq().

046f98d075 block: pass desired TLS hostname through from block driver client
In

  commit a71d597b98
  Author: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
  Date:   Thu Jun 10 13:08:00 2021 +0300

    block/nbd: reuse nbd_co_do_establish_connection() in nbd_open()

the use of the 'hostname' field from the BDRVNBDState struct was
lost, and 'nbd_connect' just hardcoded it to match the IP socket
address. This was a harmless bug at the time since we block use
with anything other than IP sockets.

Shortly though, we want to allow the caller to override the hostname
used in the TLS certificate checks. This is to allow for TLS
when doing port forwarding or tunneling. Thus we need to reinstate
the passing along of the 'hostname'.

There is a Linux kernel bug present until v5.12 that prevents
booting with FEAT_LPA2 enabled.  As a workaround for TCG,
disable this feature for machine versions prior to 7.0.

While it might at first appear that fsdev/virtfs-proxy-header.c would
need similar adjustment for darwin as file-op-9p here, a later patch in
this series disables virtfs-proxy-helper for non-Linux. Allowing
virtfs-proxy-helper on darwin could potentially be an additional
optimization later.

1c14eaabdb block: introduce snapshot-access block driver
The new block driver simply utilizes snapshot-access API of underlying
block node.

In further patches we want to use it like this:

[guest]                   [NBD export]
   |                            |
   | root                       | root
   v                 file       v
[copy-before-write]<------[snapshot-access]
   |           |
   | file      | target
   v           v
[active-disk] [temp.img]

This way, NBD client will be able to read snapshotted state of active
disk, when active disk is continued to be written by guest. This is
known as "fleecing", and currently uses another scheme based on qcow2
temporary image which backing file is active-disk. New scheme comes
with benefits - see next commit.

The other possible application is exporting internal snapshots of
qcow2, like this:

[guest]          [NBD export]
   |                  |
   | root             | root
   v       file       v
[qcow2]<---------[snapshot-access]

For this, we'll need to implement snapshot-access API handlers in
qcow2 driver, and improve snapshot-access block driver (and API) to
make it possible to select snapshot by name. Another thing to improve
is size of snapshot. Now for simplicity we just use size of bs->file,
which is OK for backup, but for qcow2 snapshots export we'll need to
imporve snapshot-access API to get size of snapshot.

45e62b464a block: fix preallocate filter: don't do unaligned preallocate requests
There is a bug in handling BDRV_REQ_NO_WAIT flag: we still may wait in
wait_serialising_requests() if request is unaligned. And this is
possible for the only user of this flag (preallocate filter) if
underlying file is unaligned to its request_alignment on start.

So, we have to fix preallocate filter to do only aligned preallocate
requests.

Next, we should fix generic block/io.c somehow. Keeping in mind that
preallocate is the only user of BDRV_REQ_NO_WAIT and that we have to
fix its behavior now, it seems more safe to just assert that we never
use BDRV_REQ_NO_WAIT with unaligned requests and add corresponding
comment. Let's do so.
