aee519c210 acpi/gpex: Exclude pxb's resources from PCI0
Exclude the resources of extra root bridges from PCI0's _CRS. Otherwise,
the resource windows would overlap in guest, and the IO resource window
would fail to be registered.

0cf8882fd0 acpi/gpex: Inform os to keep firmware resource map
There may be some differences in pci resource assignment between guest os
and firmware.

Eg. A Bridge with Bus [d2]
    -+-[0000:d2]---01.0-[d3]----01.0

    where [d2:01.00] is a pcie-pci-bridge with BAR0 (mem, 64-bit, non-pref) [size=256]
          [d3:01.00] is a PCI Device with BAR0 (mem, 64-bit, pref) [size=128K]
                                          BAR4 (mem, 64-bit, pref) [size=64M]

    In EDK2, the Resource Map would be:
        PciBus: Resource Map for Bridge [D2|01|00]
        Type = PMem64; Base = 0x8004000000;     Length = 0x4100000;     Alignment = 0x3FFFFFF
           Base = 0x8004000000; Length = 0x4000000;     Alignment = 0x3FFFFFF;  Owner = PCI [D3|01|00:20]
           Base = 0x8008000000; Length = 0x20000;       Alignment = 0x1FFFF;    Owner = PCI [D3|01|00:10]
        Type =  Mem64; Base = 0x8008100000;     Length = 0x100; Alignment = 0xFFF
    It would use 0x4100000 to calculate the root bus's PMem64 resource window.

    While in Linux, kernel will use 0x1FFFFFF as the alignment to calculate
    the PMem64 size, which would be 0x6000000. So kernel would try to
    allocate 0x6000000 from the PMem64 resource window, but since the window
    size is 0x4100000 as assigned by EDK2, the allocation would fail.

The diffences could result in resource assignment failure.

Using _DSM #5 method to inform guest os not to ignore the PCI configuration
that firmware has done at boot time could handle the differences.

e41ee85528 acpi: Add addr offset in build_crs
AML needs Address Translation offset to describe how a bridge translates
addresses accross the bridge when using an address descriptor, and
especially on ARM, the translation offset of pio resource is usually
non zero.

Therefore, it's necessary to pass offset for pio, mmio32, mmio64 and bus
number into build_crs.

Aborted (core dumped)

Have POWERNV to select PCIE_PORT. This is done through a
new PCI_POWERNV config in hw/pci-host/Kconfig since POWERNV
doesn't have a direct dependency on PCI. For this reason,
PCI_EXPRESS and MSI_NONBROKEN are also moved under
PCI_POWERNV.

ef905eff42 sabre: increase number of PCI bus IRQs from 32 to 64
The rework of the sabre IRQs in commit 6864fa3897 "sun4u: update PCI topology to
include simba PCI bridges" changed the IRQ routing so that both PCI and legacy
OBIO IRQs are routed through the sabre PCI host bridge to the CPU.

Unfortunately this commit failed to increase the number of PCI bus IRQs
accordingly meaning that access to the legacy IRQs OBIO (irqnum >= 0x20) would
overflow the PCI bus IRQ array causing strange failures running qemu-system-sparc64
in NetBSD.

Currently an object link property is used to pass a reference to the OpenPIC

This can be simplified by defining the PCI IRQs as qdev gpios and then wiring

db1015e92e Move QOM typedefs and add missing includes

This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

243af0225a trace: switch position of headers to what Meson requires
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path.  In particular the tracing headers are using
$(build_root)/$(<D).

In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".

This patch is too ugly to be applied to the Makefiles now.  It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

1de7096d83 xen: Use ERRP_GUARD()
If we want to check error after errp-function call, we need to
introduce local_err and then propagate it to errp. Instead, use
the ERRP_GUARD() macro, benefits are:
1. No need of explicit error_propagate call
2. No need of explicit local_err variable: use errp directly
3. ERRP_GUARD() leaves errp as is if it's not NULL or
   &error_fatal, this means that we don't break error_abort
   (we'll abort on error_set, not on error_propagate)

If we want to add some info to errp (by error_prepend() or
error_append_hint()), we must use the ERRP_GUARD() macro.
Otherwise, this info will not be added when errp == &error_fatal
(the program will exit prior to the error_append_hint() or
error_prepend() call).  No such cases are being fixed here.

668f62ec62 error: Eliminate error_propagate() with Coccinelle, part 1

propagating to somewhere else, we can just as well receive it there

Not exactly elegant, I'm afraid.

The "when != lbl:" is necessary to avoid transforming

         if (fun(args, &err)) {
             goto out
         }
         ...
     out:
         error_propagate(errp, err);

even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().

Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly.  I don't know what exactly "when strict" does, only that
it helps here.

The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err".  For
an example where it's too narrow, see vfio_intx_enable().

Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there.  Converted manually.

Line breaks tidied up manually.  One nested declaration of @local_err
deleted manually.  Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

    dev = pci_new(type_name);
    ...
    pci_realize_and_unref(dev, bus, &error_fatal);

and similarly for pci_create_multifunction().

Recent commit "qdev: New qdev_new(), qdev_realize(), etc." explains
why.

6842411228 qdev: Convert uses of qdev_set_parent_bus() manually
Same transformation as in the previous commit.  Manual, because
convincing Coccinelle to transform these cases is somewhere between
not worthwhile and infeasible (at least for me).

99ba777e53 qdev: Convert uses of qdev_set_parent_bus() with Coccinelle
In addition to the qdev_create() patterns converted so far, we have a
qdev_set_parent_bus() pattern.  Mostly when we embed a device in a
parent device rather than allocating it on the heap.

This pattern also puts devices in the dangerous "no QOM parent, but
plugged into bus" state I explained in recent commit "qdev: New
qdev_new(), qdev_realize(), etc."

Apply same solution: convert to qdev_realize().  Coccinelle script:

    @@
    expression dev, bus, errp;
    symbol true;
    @@
    -    qdev_set_parent_bus(DEVICE(dev), bus);
         ...

    +    qdev_realize(DEVICE(dev), bus, errp);

    -    qdev_init_nofail(DEVICE(dev));
    +    qdev_realize(DEVICE(dev), bus, &error_fatal);

Unconverted uses of qdev_set_parent_bus() remain.  They'll be
converted later in this series.

The first rule exempts hw/arm/highbank.c, because it matches along two
control flow paths there, with different @type_name.  Covered by the
next commit's manual conversions.

Missing #include "qapi/error.h" added manually.

This reverts commit b1af7959a6.

Realizing a device automatically realizes its buses, in
device_set_realized().  Realizing them in realize methods is
redundant, unless the methods themselves require them to be realized
early.  pci_vpb_realize() doesn't.  Drop the redundant bus
realization.

efa0559547 pnv/phb4: Delete unused "pnv-phb4-pec-stack" devices
The number of stacks is controlled by property "num-stacks".
pnv_pec_instance_init() creates the maximum supported number, because
the property has not been set then.  pnv_pec_realize() realizes only
the wanted number.  Works, although it can leave unrealized devices
hanging around in the QOM composition tree.  Affects machine powernv9.

Delete the unused devices by making pnv_pec_realize() unparent them.
