d0fb9657a3 docs: fix references to docs/devel/tracing.rst
Commit e50caf4a5c ("tracing: convert documentation to rST")
converted docs/devel/tracing.txt to docs/devel/tracing.rst.

We still have several references to the old file, so let's fix them
with the following command:

  sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt)

4872fdf71b hw/pci-host: Do not build gpex-acpi.c if GPEX is not selected
Since its introduction in commit 5b85eabe68 ("acpi: add
acpi_dsdt_add_gpex") we build gpex-acpi.c if ACPI is selected,
even if the GPEX_HOST device isn't build. Add the missing
Kconfig dependency.

a6091108aa hw/pci-host/gpex: Don't fault for unmapped parts of MMIO and PIO windows
Currently the gpex PCI controller implements no special behaviour for
guest accesses to areas of the PIO and MMIO where it has not mapped
any PCI devices, which means that for Arm you end up with a CPU
exception due to a data abort.

Most host OSes expect "like an x86 PC" behaviour, where bad accesses
like this return -1 for reads and ignore writes.  In the interests of
not being surprising, make host CPU accesses to these windows behave
as -1/discard where there's no mapped PCI device.

The old behaviour generally didn't cause any problems, because
almost always the guest OS will map the PCI devices and then only
access where it has mapped them. One corner case where you will see
this kind of access is if Linux attempts to probe legacy ISA
devices via a PIO window access. So far the only case where we've
seen this has been via the syzkaller fuzzer.

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.

995d955647 pnv: Fix reverse dependency on PCI express root ports
qemu-system-ppc64 built with --without-default-devices crashes:

Type 'pnv-phb4-root-port' is missing its parent 'pcie-root-port-base'
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.

40a0deb74b uninorth: use qdev gpios for PCI IRQs
Currently an object link property is used to pass a reference to the OpenPIC
into the PCI host bridge so that pci_unin_init_irqs() can connect the PCI
IRQs to the PIC itself.

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

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

668f62ec62 error: Eliminate error_propagate() with Coccinelle, part 1
When all we do with an Error we receive into a local variable is
propagating to somewhere else, we can just as well receive it there
right away.  Convert

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.

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:

The first rule exempts hw/arm/highbank.c, because it matches along two

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.

ea2fe4dfe4 hw/pci-host/prep: Correct RAVEN bus bridge memory region size
memory_region_set_size() handle the 16 Exabytes limit by
special-casing the UINT64_MAX value. This is not a problem
for the 32-bit maximum, 4 GiB.
By using the UINT32_MAX value, the bm-raven MemoryRegion
ends up missing 1 byte:

  $ qemu-system-ppc -M prep -S -monitor stdio -usb
  memory-region: bm-raven
    0000000000000000-00000000fffffffe (prio 0, i/o): bm-raven
      0000000000000000-000000003effffff (prio 0, i/o): alias bm-pci-memory @pci-memory 0000000000000000-000000003effffff

Fix by using the correct value. We now have:

  memory-region: bm-raven
    0000000000000000-00000000ffffffff (prio 0, i/o): bm-raven

8e5c952b37 hw: Remove unnecessary DEVICE() cast
The DEVICE() macro is defined as:

  #define DEVICE(obj) OBJECT_CHECK(DeviceState, (obj), TYPE_DEVICE)

which expands to:

  ((DeviceState *)object_dynamic_cast_assert((Object *)(obj), (name),
                                             __FILE__, __LINE__,
                                             __func__))

This assertion can only fail when @obj points to something other
than its stated type, i.e. when we're in undefined behavior country.

Remove the unnecessary DEVICE() casts when we already know the
pointer is of DeviceState type.

Patch created mechanically using spatch with this script:

  typedef DeviceState;
  DeviceState *s;

d2623129a7 qom: Drop parameter @errp of object_property_add() & friends
The only way object_property_add() can fail is when a property with
the same name already exists.  Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.

Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent.  Parentage is
also under program control, so this is a programming error, too.

We have a bit over 500 callers.  Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.

The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.

Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.  ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.

When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.

Drop parameter @errp and assert the preconditions instead.

There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification".  Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

64a7b8de42 qom/object: Use common get/set uint helpers
Several objects implemented their own uint property getters and setters,
despite them being straightforward (without any checks/validations on
the values themselves) and identical across objects. This makes use of
an enhanced API for object_property_add_uintXX_ptr() which offers

Some of these setters used to update the value even if the type visit
failed (eg. because the value being set overflowed over the given type).
The new setter introduces a check for these errors, not updating the
value if an error occurred. The error is propagated.

9ae1329ee2 ppc/pnv: Add models for POWER8 PHB3 PCIe Host bridge
This is a model of the PCIe Host Bridge (PHB3) found on a POWER8
processor. It includes the PowerBus logic interface (PBCQ), IOMMU
support, a single PCIe Gen.3 Root Complex, and support for MSI and LSI
interrupt sources as found on a POWER8 system using the XICS interrupt
controller.

The POWER8 processor comes in different flavors: Venice, Murano,
Naple, each having a different number of PHBs. To make things simpler,
the models provides 3 PHB3 per chip. Some platforms, like the
Firestone, can also couple PHBs on the first chip to provide more
bandwidth but this is too specific to model in QEMU.

XICS requires some adjustment to support the PHB3 MSI. The changes are
provided here but they could be decoupled in prereq patches.

4f9924c4d4 ppc/pnv: Add models for POWER9 PHB4 PCIe Host bridge
These changes introduces models for the PCIe Host Bridge (PHB4) of the
POWER9 processor. It includes the PowerBus logic interface (PBCQ),
IOMMU support, a single PCIe Gen.4 Root Complex, and support for MSI
and LSI interrupt sources as found on a POWER9 system using the XIVE
interrupt controller.

POWER9 processor comes with 3 PHB4 PEC (PCI Express Controller) and
each PEC can have several PHBs. By default,

  * PEC0 provides 1 PHB  (PHB0)
  * PEC1 provides 2 PHBs (PHB1 and PHB2)
  * PEC2 provides 3 PHBs (PHB3, PHB4 and PHB5)

Each PEC has a set  "global" registers and some "per-stack" (per-PHB)
registers. Those are organized in two XSCOM ranges, the "Nest" range
and the "PCI" range, each range contains both some "PEC" registers and
some "per-stack" registers.

No default device layout is provided and PCI devices can be added on
any of the available PCIe Root Port (pcie.0 .. 2 of a Power9 chip)
with address 0x0 as the firwware (skiboot) only accepts a single
device per root port. To run a simple system with a network and a
storage adapters, use a command line options such as :

  -device e1000e,netdev=net0,mac=C0:FF:EE:00:00:02,bus=pcie.0,addr=0x0
  -netdev bridge,id=net0,helper=/usr/libexec/qemu-bridge-helper,br=virbr0,id=hostnet0

  -device megasas,id=scsi0,bus=pcie.1,addr=0x0
  -drive file=$disk,if=none,id=drive-scsi0-0-0-0,format=qcow2,cache=none
  -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=2

If more are needed, include a bridge.

Multi chip is supported, each chip adding its set of PHB4 controllers
and its PCI busses. The model doesn't emulate the EEH error handling.

This model is not ready for hotplug yet.

6cdda0ff4b hw/core/loader: Let load_elf() populate a field with CPU-specific flags
While loading the executable, some platforms (like AVR) need to
detect CPU type that executable is built for - and, with this patch,
this is enabled by reading the field 'e_flags' of the ELF header of
the executable in question. The change expands functionality of
the following functions:

  - load_elf()
  - load_elf_as()
  - load_elf_ram()
  - load_elf_ram_sym()

The argument added to these functions is called 'pflags' and is of
type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word'
being the type of the field 'e_flags', in both 32-bit and 64-bit
variants of ELF header). Callers are allowed to pass NULL as that
argument, and in such case no lookup to the field 'e_flags' will
happen, and no information will be returned, of course.

f404220e27 q35: implement 128K SMRAM at default SMBASE address
It's not what real HW does, implementing which would be overkill [**]
and would require complex cross stack changes (QEMU+firmware) to make
it work.
So considering that SMRAM is owned by MCH, for simplicity (ab)use
reserved Q35 register, which allows QEMU and firmware easily init
and make RAM at SMBASE available only from SMM context.

Patch uses commit (2f295167e0 q35/mch: implement extended TSEG sizes)
for inspiration and uses reserved register in config space at 0x9c
offset [*] to extend q35 pci-host with ability to use 128K at
0x30000 as SMRAM and hide it (like TSEG) from non-SMM context.

Usage:
  1: write 0xff in the register
  2: if the feature is supported, follow up read from the register
     should return 0x01. At this point RAM at 0x30000 is still
     available for SMI handler configuration from non-SMM context
  3: writing 0x02 in the register, locks SMBASE area, making its contents
     available only from SMM context. In non-SMM context, reads return
     0xff and writes are ignored. Further writes into the register are
     ignored until the system reset.

8ce60a7518 hw/i386: Remove obsolete LoadStateHandler::load_state_old handlers
These devices implemented their load_state_old() handler 10 years
ago, previous to QEMU v0.12.
Since commit cc425b5ddf removed the pc-0.10 and pc-0.11 machines,
we can drop this code.

Note: the mips_r4k machine started to use the i8254 device just
after QEMU v0.5.0, but the MIPS machine types are not versioned,
so there is no migration compatibility issue removing this handler.

54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)

Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

so that MSI mapping is updated when enabled transitions from either

unconditionally instead of trying to fix the update_msi_mapping logic.

4a4418369d q35: fix mmconfig and PCI0._CRS
This patch changes the handling of the mmconfig area.  Thanks to the
pci(e) expander devices we already have the logic to exclude address
ranges from PCI0._CRS.  We can simply add the mmconfig address range
to the list get it excluded as well.

With that in place we can go with a fixed pci hole which covers the
whole area from the end of (low) ram to the ioapic.

This will make the whole logic alot less fragile.  No matter where the
firmware places the mmconfig xbar, things should work correctly.  The
guest also gets a bit more PCI address space (seabios boot):

    # cat /proc/iomem
    [ ... ]
    7ffdd000-7fffffff : reserved
    80000000-afffffff : PCI Bus 0000:00            <<-- this is new
    b0000000-bfffffff : PCI MMCONFIG 0000 [bus 00-ff]
      b0000000-bfffffff : reserved
    c0000000-febfffff : PCI Bus 0000:00
      f8000000-fbffffff : 0000:00:01.0
    [ ... ]

So this is a guest visible change.

aff39be0ed hw/pci-host: Use object_initialize_child for correct reference counting
Both functions, object_initialize() and object_property_add_child() increase
the reference counter of the new object, so one of the references has to be
dropped afterwards to get the reference counting right. Otherwise the child
object might not be properly cleaned up when the parent gets destroyed.
Some functions of the pci-host devices miss to drop one of the references.
Fix it by using object_initialize_child() instead, which takes care of
calling object_initialize(), object_property_add_child() and object_unref()
in the right order.

MSI to work but it won't due to the buggy or lacking emulation.

In QEMU this is represented by the "msi_nonbroken" variable.  This
patch adds a new configuration symbol enabled whenever the binary
contains an interrupt controller that will set "msi_nonbroken".  We
can then use it to remove devices that cannot be possibly added
to the machine, because they require MSI.

7c28b925b7 build: convert pci.mak to Kconfig
Instead of including the same list of devices for each target,
set CONFIG_PCI to true, and make the devices default to present
whenever PCI is available.  However, s390x does not want all the
PCI devices, so there is a separate symbol to enable them.

Done mostly with the following script:

  while read i; do
     i=${i%=y}; i=${i#CONFIG_}
     sed -i -e'/^config '$i'$/!b' -en \
            -e'a\' -e'    default y if PCI_DEVICES\' -e'    depends on PCI' \
          `grep -lw $i hw/*/Kconfig`
  done < default-configs/pci.mak

followed by replacing a few "depends on" clauses with "select"
whenever the symbol is not really related to PCI.

Whenever a symbol is referenced from multiple subdirectories, the

These symbols have to be added manually to the Kconfig files.

Kconfig.host and hw/Kconfig were created manually.

4366e1db16 elf: Add optional function ptr to load_elf() to parse ELF notes
This patch adds an optional function pointer, 'elf_note_fn', to
load_elf() which causes load_elf() to additionally parse any
ELF program headers of type PT_NOTE and check to see if the ELF
Note is of the type specified by the 'translate_opaque' arg.
If a matching ELF Note is found then the specfied function pointer
is called to process the ELF note.

Passing a NULL function pointer results in ELF Notes being skipped.

The first consumer of this functionality is the PVHboot support
which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while
loading the uncompressed kernel binary in order to discover the
boot entry address for the x86/HVM direct boot ABI.

d4715481de i386: clarify that the Q35 machine type implements a P35 chipset
The 'q35' machine type implements an Intel Series 3 chipset,
of which there are several variants:

  https://www.intel.com/Assets/PDF/datasheet/316966.pdf

The key difference between the 82P35 MCH ('p35', PCI device ID 0x29c0)
and 82Q35 GMCH ('q35', PCI device ID 0x29b0) variants is that the latter
has an integrated graphics adapter. QEMU does not implement integrated
graphics, so uses the PCI ID for the 82P35 chipset, despite calling the
machine type 'q35'. Thus we rename the PCI device ID constant to reflect
reality, to avoid confusing future developers. The new name more closely
matches what pci.ids reports it to be:

$ grep  P35 /usr/share/hwdata/pci.ids  | grep 29
	29c0  82G33/G31/P35/P31 Express DRAM Controller
	29c1  82G33/G31/P35/P31 Express PCI Express Root Port
	29c4  82G33/G31/P35/P31 Express MEI Controller
	29c5  82G33/G31/P35/P31 Express MEI Controller
	29c6  82G33/G31/P35/P31 Express PT IDER Controller
	29c7  82G33/G31/P35/P31 Express Serial KT Controller

$ grep  Q35 /usr/share/hwdata/pci.ids  | grep 29
	29b0  82Q35 Express DRAM Controller
	29b1  82Q35 Express PCI Express Root Port
	29b2  82Q35 Express Integrated Graphics Controller
	29b3  82Q35 Express Integrated Graphics Controller
	29b4  82Q35 Express MEI Controller
	29b5  82Q35 Express MEI Controller
	29b6  82Q35 Express PT IDER Controller
	29b7  82Q35 Express Serial KT Controller

Arguably the QEMU machine type should be named 'p35'. At this point in
time, however, it is not worth the churn for management applications &
documentation to worry about renaming it.

ed6bb4b581 hw/pci-host/x86: extend the 64-bit PCI hole relative to the fw-assigned base
In commit 9fa99d2519 ("hw/pci-host: Fix x86 Host Bridges 64bit PCI
hole", 2017-11-16), we meant to expose such a 64-bit PCI MMIO aperture in
the ACPI DSDT that would be at least as large as the new "pci-hole64-size"
property (2GB on i440fx, 32GB on q35). The goal was to offer "enough"
64-bit MMIO aperture to the guest OS for hotplug purposes.

In that commit, we added or modified five functions:

- pc_pci_hole64_start(): shared between i440fx and q35. Provides a default
  64-bit base, which starts beyond the cold-plugged 64-bit RAM, and skips
  the DIMM hotplug area too (if any).

- i440fx_pcihost_get_pci_hole64_start(), q35_host_get_pci_hole64_start():
  board-specific 64-bit base property getters called abstractly by the
  ACPI generator. Both of these fall back to pc_pci_hole64_start() if the
  firmware didn't program any 64-bit hole (i.e. if the firmware didn't
  assign a 64-bit GPA to any MMIO BAR on any device). Otherwise, they
  honor the firmware's BAR assignments (i.e., they treat the lowest 64-bit
  GPA programmed by the firmware as the base address for the aperture).

- i440fx_pcihost_get_pci_hole64_end(), q35_host_get_pci_hole64_end():
  these intended to extend the aperture to our size recommendation,
  calculated relative to the base of the aperture.

Despite the original intent, i440fx_pcihost_get_pci_hole64_end() and
q35_host_get_pci_hole64_end() currently only extend the aperture relative
to the default base (pc_pci_hole64_start()), ignoring any programming done
by the firmware. This means that our size recommendation may not be met.
Fix it by honoring the firmware's address assignments.

The strange extension sizes were spotted by Alex, in the log of a guest
kernel running on top of OVMF (which prefers to assign 64-bit GPAs to
64-bit BARs).

This change only affects DSDT generation, therefore no new compat property
is being introduced.

Using an i440fx OVMF guest with 5GB RAM, an example _CRS change is:

(On i440fx, the low RAM split is at 3GB, in this case. Therefore, with 5GB
guest RAM and no DIMM hotplug range, pc_pci_hole64_start() returns 4 +
(5-3) = 6 GB. Adding the 2GB extension to that yields 8GB, which is below
the firmware-programmed base of 32GB, before the patch. Therefore, before
the patch, the extension is ineffective. After the patch, we add the 2GB
extension to the firmware-programmed base, namely 32GB.)

(On Q35, the low RAM split is at 2GB. Therefore, with 5GB guest RAM and no
DIMM hotplug range, pc_pci_hole64_start() returns 4 + (5-2) = 7 GB. Adding
the 32GB extension to that yields 39GB (0x0000_0009_BFFF_FFFF + 1), before

f40b83a4e3 40p: use OR gate to wire up raven PCI interrupts
According to the PReP specification section 6.1.6 "System Interrupt
Assignments", all PCI interrupts are routed via IRQ 15.

Instead of mapping each PCI IRQ separately, we introduce an OR gate within the
raven PCI host bridge and then wire the single output of the OR gate to the
interrupt controller.

Note that whilst the (now deprecated) PReP machine still exists we still need
to preserve the old IRQ routing. This is done by adding a new "is-legacy-prep"
property to the raven PCI host bridge which is set to true for the PReP
machine.

4f91740698 hw/pci-host/xilinx-pcie: don't make "io" region be RAM
Currently we use memory_region_init_rom_nomigrate() to create
the "io" memory region to pass to pci_register_root_bus().
This is a dummy region, because this PCI controller doesn't
support accesses to PCI IO space.

There is no reason for the dummy region to be a RAM region;
it is only used as a place where PCI BARs can be mapped,
and if you could get a PCI card to do a bus master access
to the IO space it should not get acts-like-RAM behaviour.
Use a simple container memory region instead. (We do have
one PCI card model which can do bus master accesses to IO
space -- the LSI53C895A SCSI adaptor.)

This avoids the oddity of having a memory region which is
RAM but where the RAM is not migrated.

Note that the size of the region we use here has no
effect on behaviour.

e226efbb26 uninorth: move PCI IO (ISA) memory region into the uninorth device
Do this for both the uninorth main and uninorth u3 AGP buses, using the main
PCI bus for each machine (this ensures the IO addresses still match those
used by OpenBIOS).

c1d66d378c uninorth: fix PCI and AGP bus mixup
Somewhere in the history of time, the initialisation of the PCI buses for the
AGP and PCI host bridges got mixed up in that the PCI host bridge was
creating an instance of the AGP PCI bus, and the AGP PCI bus was missing.

Swap the PCI host bridge over to use the correct PCI bus (including setting
the kMacRISCPCIAddressSelect register used by MacOS X) and add the missing
reference to the AGP PCI bus.

32cde6154c uninorth: move PCI host bridge bus initialisation into device realize
Since the IO address space is fixed to use the standard system IO address

parameter from pci_pmac_init() and pci_pmac_u3_init().

Note we also move the default mac99 PCI bus to the end of the initialisation
list so that it becomes the default destination for any devices specified
via -device without an explicit PCI bus provided.

Devices that implements only INTERFACE_PCIE_DEVICE (is_express == 1)
or
devices that implements only INTERFACE_CONVENTIONAL_PCI_DEVICE (is_express == 0)
where not affected by the change.

The only devices that were affected are those that are hybrid and also
had (is_express == 1) - therefor only:
  - hw/vfio/pci.c
  - hw/usb/hcd-xhci.c
  - hw/xen/xen_pt.c

For those 3 I made sure that QEMU_PCI_CAP_EXPRESS is on in instance_init()
