a779e37c68 aspeed/smc: Introduce a new addr_width() class handler
The AST2400 SPI controller has a transitional HW interface and it
stores the address width currently in use in a different register than
all the other SMC controllers. It needs special handling when working
in 4B mode.

Make it clear through a class handler. This also removes another use
of the segments array.

f75b533117 aspeed/smc: QOMify AspeedSMCFlash
AspeedSMCFlash is a small structure representing the AHB memory window
through which the contents of a flash device can be accessed with MMIOs.

Introduce an AspeedSMCFlash SysBusDevice model and attach the associated
memory region to the newly instantiated objects.

df8abbbadf macfb: add common monitor modes supported by the MacOS toolbox ROM
The monitor modes table is found by experimenting with the Monitors Control
Panel in MacOS and analysing the reads/writes. From this it can be found that
the mode is controlled by writes to the DAFB_MODE_CTRL1 and DAFB_MODE_CTRL2
registers.

Implement the first block of DAFB registers as a register array including the
existing sense register, the newly discovered control registers above, and also
the DAFB_MODE_VADDR1 and DAFB_MODE_VADDR2 registers which are used by NetBSD to
determine the current video mode.

These experiments also show that the offset of the start of video RAM and the
stride can change depending upon the monitor mode, so update macfb_draw_graphic()
and both the BI_MAC_VADDR and BI_MAC_VROW bootinfo for the q800 machine
accordingly.

Finally update macfb_common_realize() so that only the resolution and depth
supported by the display type can be specified on the command line, and add an
error hint showing the list of supported resolutions and depths if the user tries
to specify an invalid display mode.

The main resolutions of interest are high resolution 1152x870 with 8-bit colour

08b83bff2a job: Add job_cancel_requested()
Most callers of job_is_cancelled() actually want to know whether the job
is on its way to immediate termination.  For example, we refuse to pause
jobs that are cancelled; but this only makes sense for jobs that are
really actually cancelled.

A mirror job that is cancelled during READY with force=false should
absolutely be allowed to pause.  This "cancellation" (which is actually
a kind of completion) may take an indefinite amount of time, and so
should behave like any job during normal operation.  For example, with
on-target-error=stop, the job should stop on write errors.  (In
contrast, force-cancelled jobs should not get write errors, as they
should just terminate and not do further I/O.)

Therefore, redefine job_is_cancelled() to only return true for jobs that
are force-cancelled (which as of HEAD^ means any job that interprets the
cancellation request as a request for immediate termination), and add
job_cancel_requested() as the general variant, which returns true for
any jobs which have been requested to be cancelled, whether it be
immediately or after an arbitrarily long completion phase.

Finally, here is a justification for how different job_is_cancelled()
invocations are treated by this patch:

- block/mirror.c (mirror_run()):
  - The first invocation is a while loop that should loop until the job
    has been cancelled or scheduled for completion.  What kind of cancel
    does not matter, only the fact that the job is supposed to end.

  - The second invocation wants to know whether the job has been
    soft-cancelled.  Calling job_cancel_requested() is a bit too broad,
    but if the job were force-cancelled, we should leave the main loop
    as soon as possible anyway, so this should not matter here.

  - The last two invocations already check force_cancel, so they should
    continue to use job_is_cancelled().

- block/backup.c, block/commit.c, block/stream.c, anything in tests/:
  These jobs know only force-cancel, so there is no difference between
  job_is_cancelled() and job_cancel_requested().  We can continue using
  job_is_cancelled().

- job.c:
  - job_pause_point(), job_yield(), job_sleep_ns(): Only force-cancelled
    jobs should be prevented from being paused.  Continue using job_is_cancelled().

  - job_update_rc(), job_finalize_single(), job_finish_sync(): These
    functions are all called after the job has left its main loop.  The
    mirror job (the only job that can be soft-cancelled) will clear
    .cancelled before leaving the main loop if it has been
    soft-cancelled.  Therefore, these functions will observe .cancelled
    to be true only if the job has been force-cancelled.  We can
    continue to use job_is_cancelled().
    (Furthermore, conceptually, a soft-cancelled mirror job should not
    report to have been cancelled.  It should report completion (see
    also the block-job-cancel QAPI documentation).  Therefore, it makes
    sense for these functions not to distinguish between a
    soft-cancelled mirror job and a job that has completed as normal.)

  - job_completed_txn_abort(): All jobs other than @job have been
    force-cancelled.  job_is_cancelled() must be true for them.
    Regarding @job itself: job_completed_txn_abort() is mostly called
    when the job's return value is not 0.  A soft-cancelled mirror has a
    return value of 0, and so will not end up here then.
    However, job_cancel() invokes job_completed_txn_abort() if the job
    has been deferred to the main loop, which is mostly the case for
    completed jobs (which skip the assertion), but not for sure.
    To be safe, use job_cancel_requested() in this assertion.

  - job_complete(): This is function eventually invoked by the user
    (through qmp_block_job_complete() or qmp_job_complete(), or
    job_complete_sync(), which comes from qemu-img).  The intention here
    is to prevent a user from invoking job-complete after the job has
    been cancelled.  This should also apply to soft cancelling: After a
    mirror job has been soft-cancelled, the user should not be able to
    decide otherwise and have it complete as normal (i.e. pivoting to
    the target).

  - job_cancel(): Both functions are equivalent (see comment there), but
    we want to use job_is_cancelled(), because this shows that we call
    job_completed_txn_abort() only for force-cancelled jobs.  (As
    explained for job_update_rc(), soft-cancelled jobs should be treated
    as if they have completed as normal.)

73895f3838 jobs: Give Job.force_cancel more meaning
We largely have two cancel modes for jobs:

First, there is actual cancelling.  The job is terminated as soon as
possible, without trying to reach a consistent result.

Second, we have mirror in the READY state.  Technically, the job is not
really cancelled, but it just is a different completion mode.  The job
can still run for an indefinite amount of time while it tries to reach a
consistent result.

We want to be able to clearly distinguish which cancel mode a job is in
(when it has been cancelled).  We can use Job.force_cancel for this, but
right now it only reflects cancel requests from the user with
force=true, but clearly, jobs that do not even distinguish between
force=false and force=true are effectively always force-cancelled.

So this patch has Job.force_cancel signify whether the job will
terminate as soon as possible (force_cancel=true) or whether it will
effectively remain running despite being "cancelled"
(force_cancel=false).

To this end, we let jobs that provide JobDriver.cancel() tell the
generic job code whether they will terminate as soon as possible or not,
and for jobs that do not provide that method we assume they will.

4cfb3f0562 job: @force parameter for job_cancel_sync()
Callers should be able to specify whether they want job_cancel_sync() to
force-cancel the job or not.

In fact, almost all invocations do not care about consistency of the
result and just want the job to terminate as soon as possible, so they
should pass force=true.  The replication block driver is the exception,
specifically the active commit job it runs.

As for job_cancel_sync_all(), all callers want it to force-cancel all
jobs, because that is the point of it: To cancel all remaining jobs as
quickly as possible (generally on process termination).  So make it
invoke job_cancel_sync() with force=true.

This changes some iotest outputs, because quitting qemu while a mirror
job is active will now lead to it being cancelled instead of completed,
which is what we want.  (Cancelling a READY mirror job with force=false
may take an indefinite amount of time, which we do not want when
quitting.  If users want consistent results, they must have all jobs be
done before they quit qemu.)

- Register device in 'input' category
- Keep mchp_pfsoc_mmuart_create() behavior

Note, serial_mm_init() calls qdev_set_legacy_instance_id().
This call is only needed for backwards-compatibility of incoming
migration data with old versions of QEMU which implemented migration
of devices with hand-rolled code. Since this device didn't previously
handle migration at all, then it doesn't need to set the legacy
instance ID.

cc07162953 block: introduce max_hw_iov for use in scsi-generic
Linux limits the size of iovecs to 1024 (UIO_MAXIOV in the kernel
sources, IOV_MAX in POSIX).  Because of this, on some host adapters
requests with many iovecs are rejected with -EINVAL by the
io_submit() or readv()/writev() system calls.

In fact, the same limit applies to SG_IO as well.  To fix both the
EINVAL and the possible performance issues from using fewer iovecs
than allowed by Linux (some HBAs have max_segments as low as 128),
introduce a separate entry in BlockLimits to hold the max_segments
value from sysfs.  This new limit is used only for SG_IO and clamped
to bs->bl.max_iov anyway, just like max_hw_transfer is clamped to
bs->bl.max_transfer.

db637f270b tcg: add dup_const_tl wrapper
dup_const always generates a uint64_t, which may exceed the size of a
target_long (generating warnings with recent-enough compilers).

To ensure that we can use dup_const both for 64bit and 32bit targets,
this adds dup_const_tl, which either maps back to dup_const (for 64bit
targets) or provides a similar implementation using 32bit constants.

0e780da76a hw/i386/acpi: fix conflicting IO address range for acpi pci hotplug in q35
Change caf108bc58 ("hw/i386/acpi-build: Add ACPI PCI hot-plug methods to Q35")
selects an IO address range for acpi based PCI hotplug for q35 arbitrarily. It
starts at address 0x0cc4 and ends at 0x0cdb. At the time when the patch was
written but the final version of the patch was not yet pushed upstream, this
address range was free and did not conflict with any other IO address ranges.
However, with the following change, this address range was no
longer conflict free as in this change, the IO address range
(value of ACPI_PCIHP_SIZE) was incremented by four bytes:

b32bd763a1 ("pci: introduce acpi-index property for PCI device")

This can be seen from the output of QMP command 'info mtree' :

0000000000000600-0000000000000603 (prio 0, i/o): acpi-evt
0000000000000604-0000000000000605 (prio 0, i/o): acpi-cnt
0000000000000608-000000000000060b (prio 0, i/o): acpi-tmr
0000000000000620-000000000000062f (prio 0, i/o): acpi-gpe0
0000000000000630-0000000000000637 (prio 0, i/o): acpi-smi
0000000000000cc4-0000000000000cdb (prio 0, i/o): acpi-pci-hotplug
0000000000000cd8-0000000000000ce3 (prio 0, i/o): acpi-cpu-hotplug

It shows that there is a region of conflict between IO regions of acpi
pci hotplug and acpi cpu hotplug.

Unfortunately, the change caf108bc58 did not update the IO address range
appropriately before it was pushed upstream to accommodate the increased
length of the IO address space introduced in change b32bd763a1.

Due to this bug, windows guests complain 'This device cannot find
enough free resources it can use' in the device manager panel for extended
IO buses. This issue also breaks the correct functioning of pci hotplug as the
following shows that the IO space for pci hotplug has been truncated:

(qemu) info mtree -f
FlatView #0
 AS "I/O", root: io
 Root memory region: io
  0000000000000cc4-0000000000000cd7 (prio 0, i/o): acpi-pci-hotplug
  0000000000000cd8-0000000000000cf7 (prio 0, i/o): acpi-cpu-hotplug

Therefore, in this fix, we adjust the IO address range for the acpi pci
hotplug so that it does not conflict with cpu hotplug and there is no
truncation of IO spaces. The starting IO address of PCI hotplug region
has been decremented by four bytes in order to accommodate four byte
increment in the IO address space introduced by change
b32bd763a1 ("pci: introduce acpi-index property for PCI device")

After fixing, the following are the corrected IO ranges:

0000000000000600-0000000000000603 (prio 0, i/o): acpi-evt
0000000000000604-0000000000000605 (prio 0, i/o): acpi-cnt
0000000000000608-000000000000060b (prio 0, i/o): acpi-tmr
0000000000000620-000000000000062f (prio 0, i/o): acpi-gpe0
0000000000000630-0000000000000637 (prio 0, i/o): acpi-smi
0000000000000cc0-0000000000000cd7 (prio 0, i/o): acpi-pci-hotplug
0000000000000cd8-0000000000000ce3 (prio 0, i/o): acpi-cpu-hotplug

This change has been tested using a Windows Server 2019 guest VM. Windows
no longer complains after this change.

Spec is Microsoft hosted, however 1.02 is no where to be found

so bring comments in line with 1.07 as this is the only available spec.
There is no content change between originally implemented 1.02

57cb8cfbf2 acpi: build_tpm_tcpa: use acpi_table_begin()/acpi_table_end() instead of build_header()
it replaces error-prone pointer arithmetic for build_header() API,
with 2 calls to start and finish table creation,
which hides offsets magic from API user.

While at it switch to build_append_int_noprefix() to build
table entries (which also removes some manual offset
calculations).

c151fd8710 acpi: add helper routines to initialize ACPI tables
Patch introduces acpi_table_begin()/ acpi_table_end() API
that hides pointer/offset arithmetic from user as opposed
to build_header(), to prevent errors caused by it [1].

 acpi_table_begin():
     initializes table header and keeps track of
     table data/offsets
 acpi_table_end():
     sets actual table length and tells bios loader
     where table is for the later initialization on
     guest side.

46ce017167 vhost-vsock: handle common features in vhost-vsock-common
virtio-vsock features, like VIRTIO_VSOCK_F_SEQPACKET, can be handled
by vhost-vsock-common parent class. In this way, we can reuse the
same code for all virtio-vsock backends (i.e. vhost-vsock,
vhost-user-vsock).

Let's move `seqpacket` property to vhost-vsock-common class, add
vhost_vsock_common_get_features() used by children, and disable
`seqpacket` for vhost-user-vsock device for machine types < 6.2.

The behavior of vhost-vsock device doesn't change; vhost-user-vsock
device now supports `seqpacket` property.
