650d103d3e Include hw/hw.h exactly where needed
In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).

The previous commits have left only the declaration of hw_error() in
hw/hw.h.  This permits dropping most of its inclusions.  Touching it
now recompiles less than 200 objects.

recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

hw/hw.h supposedly includes it for convenience.  Several other headers

now recompiles only some 1600 objects.

4eb42b81c5 pci: designware: Update MSI mapping unconditionally
Expression to calculate update_msi_mapping in code handling writes to
DESIGNWARE_PCIE_MSI_INTR0_ENABLE is missing an ! operator and should
be:

    !!root->msi.intr[0].enable ^ !!val;

so that MSI mapping is updated when enabled transitions from either
"none" -> "any" or "any" -> "none". Since that register shouldn't be
written to very often, change the code to update MSI mapping
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.

ca9b7e29de kconfig: add CONFIG_MSI_NONBROKEN
Not all interrupt controllers have a working implementation of
message-signalled interrupts; in some cases, the guest may expect
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.

  for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* | sort -u`; do
    set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' `
    shift
    if test $# = 1; then
      cat >> $(dirname $1)/Kconfig << EOF
config ${i#CONFIG_}
    bool

EOF
      git add $(dirname $1)/Kconfig
    else

    fi
  done
  sed -i '$d' hw/*/Kconfig
  for i in hw/*; do
    if test -d $i && ! test -f $i/Kconfig; then
      touch $i/Kconfig
      git add $i/Kconfig
    fi
  done

Whenever a symbol is referenced from multiple subdirectories, the
script prints the list of directories that reference the symbol.
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
the patch. After the patch, we add the 32GB extension to the
firmware-programmed base, namely 32GB.)

this series are corrected too, as follows:

Here are the accumulated ppc target patches for the last several
 weeks. Highlights are:
    * A number of 40p / PReP cleanups
    * Preliminary irq rework on the pseries machine towards the new
      XIVE interrupt controller
 
 There are a few patches which make small changes to generic device and
 arm code as prerequisites to the 40p interrupt routing cleanup.  They
 have acks from the relevant maintainers.

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.

55a2290254 raven: some minor IRQ-related tidy-ups
This really lays the groundwork for the upcoming patches: it renames the
irqs PREPPCIState struct member to pci_irqs (as soon there will be a
distinction) and then changes the raven IRQ opaque to use PREPPCIState
instead of just irqs array.

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.
