91f4c995f2 pci: Make is_bridge a bool
The is_bridge field in PCIDevice acts as a bool, but is declared as an int.
Declare it as a bool for clarity, and change everything that writes it to
use true/false instead of 0/1 to match.

b0e5196a52 pci: Simplify pci_bus_is_root()
pci_bus_is_root() currently relies on a method in the PCIBusClass.
But it's always known if a PCI bus is a root bus when we create it, so
using a dynamic method is overkill.

This replaces it with an IS_ROOT bit in a new flags field, which is set on
root buses and otherwise clear.  As a bonus this removes the special
is_root logic from pci_expander_bridge, since it already creates its bus
as a root bus.

d6c1bd4a22 kconfig: add dependencies on CONFIG_MSI_NONBROKEN
For devices that require msi_init/msix_init to succeed, add a
dependency on CONFIG_MSI_NONBROKEN.  This will prevent those devices
from appearing in a binary that cannot instantiate them.

e07fb4b50b gen_pcie_root_port: Add ACS (Access Control Services) capability
Claim ACS support in the generic PCIe root port to allow
passthrough of individual functions of a device to different
guests (in a nested virt.setting) with VFIO.
Without this patch, all functions of a device, such as all VFs of
an SR/IOV device, will end up in the same IOMMU group.
A similar situation occurs on Windows with Hyper-V.

In the single function device case, it also has a small cosmetic
benefit in that the root port itself is not grouped with
the device. VFIO handles that situation in that binding rules
only apply to endpoints, so it does not limit passthrough in
those cases.

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.

82f5181777 kconfig: introduce kconfig files

  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
      echo $i $*
    fi
  done
  sed -i '$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.

8f560cdce4 pci/shpc: perform unplug via the hotplug handler
Introduce and use the "unplug" callback.

This is a preparation for multi-stage hotplug handlers, whereby the bus
hotplug handler is overwritten by the machine hotplug handler. This handler
will then pass control to the bus hotplug handler. So to get this running
cleanly, we also have to make sure to go via the hotplug handler chain when
actually unplugging a device after an unplug request. Lookup the hotplug
handler and call "unplug".

c2a490e344 pcie: Allow generic PCIe root port to specify link speed and width
Allow users to experimentally specify speed and width values for the
generic PCIe root port.  Defaults remain at 2.5GT/s & x1 for
compatiblity with the intent to only support changing defaults via
machine types for now.

Note for libvirt testing that pcie-root-port controllers are given
default names like "pci.7" which don't play well with using the
"-set device.$name.$prop=$value" options accessible to us via
<qemu:commandline> options.  The solution is to add an <alias> to the
pcie-root-port <controller>, for example:

    <controller type='pci' index='7' model='pcie-root-port'>
      <model name='pcie-root-port'/>
      <target chassis='7' port='0x15'/>
      <alias name='ua-gfx0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x5'/>
    </controller>

The "ua-" here is a mandatory prefix.  We can then use:

  <qemu:commandline>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.ua-gfx0.x-speed=8'/>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.ua-gfx0.x-width=16'/>
  </qemu:commandline>

or, without an alias, set globals such as:

  <qemu:commandline>
    <qemu:arg value='-global'/>
    <qemu:arg value='pcie-root-port.x-speed=8'/>
    <qemu:arg value='-global'/>
    <qemu:arg value='pcie-root-port.x-width=16'/>
  </qemu:commandline>

9d6b9db19c pci/bus: let it has higher migration priority
In the past, we prioritized IOMMU migration so that we have such a
priority order:

    IOMMU > PCI Devices

When migrating a guest with both vIOMMU and a pcie-root-port, we'll
always migrate vIOMMU first, since pci buses will be seen to have the
same priority of general PCI devices.

That's problematic.

The thing is that PCI bus number information is stored in the root port,
and that is needed by vIOMMU during post_load(), e.g., to figure out
context entry for a device.  If we don't have correct bus numbers for
devices, we won't be able to recover device state of the DMAR memory
regions, and things will be messed up.

So let's boost the PCIe root ports to be even with higher priority:

   PCIe Root Port > IOMMU > PCI Devices

A smoke test shows that this patch fixes bug 1538953.

Also, apply this rule to all the PCI bus/bridge devices: ioh3420,
xio3130_downstream, xio3130_upstream, pcie_pci_bridge, pci-pci bridge,
i82801b11.

I noted that we set pcie_pci_bridge_dev_vmstate twice.  Clean that up
together.

ed247f40db pci-bridge/i82801b11: clear bridge registers on platform reset
The "i82801b11-bridge" device model is a descendant of "base-pci-bridge"
(TYPE_PCI_BRIDGE). However, unlike other similar devices, such as

- pci-bridge,
- pcie-pci-bridge,
- PCIE Root Port,
- xio3130 switch upstream and downstream ports,
- dec-21154-p2p-bridge,
- pbm-bridge,
- xilinx-pcie-root,

"i82801b11-bridge" does not clear the bridge specific registers at
platform reset.

This is a problem because devices on "i82801b11-bridge" continue to
respond to config space cycles after platform reset, when addressed with
the bus number that was previously programmed into the secondary bus
number register of "i82801b11-bridge". This error breaks OVMF's search for
extra (PXB) root buses, for example.

The device class reset method for "i82801b11-bridge" is currently NULL;
set it directly to pci_bridge_reset(), like the last three bridge models
in the above listing do.

fced4d00e6 hw/pci-bridge: fix QEMU crash because of pcie-root-port
If we try to use more pcie_root_ports then available slots
and an IO hint is passed to the port, QEMU crashes because
we try to init the "IO hint" capability even if the device
is not created.
Fix it by checking for error before adding the capability,
so QEMU can fail gracefully.

fd56e0612b pci: Eliminate redundant PCIDevice::bus pointer
The bus pointer in PCIDevice is basically redundant with QOM information.
It's always initialized to the qdev_get_parent_bus(), the only difference
is the type.

Therefore this patch eliminates the field, instead creating a pci_get_bus()
helper to do the type mangling to derive it conveniently from the QOM
Device object underneath.

1115ff6d26 pci: Rename root bus initialization functions for clarity
pci_bus_init(), pci_bus_new_inplace(), pci_bus_new() and pci_register_bus()
are misleadingly named.  They're not used for initializing *any* PCI bus,
but only for a root PCI bus.

Non-root buses - i.e. ones under a logical PCI to PCI bridge - are instead
created with a direct qbus_create_inplace() (see pci_bridge_initfn()).

This patch renames the functions to make it clear they're only used for
a root bus.

fd3b02c889 pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devices
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:

1) The ones that already have INTERFACE_PCIE_DEVICE set:

* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3

2) base-pci-bridge

Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:

* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge

The direct subtypes of base-pci-bridge not touched by this patch
are:

* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
  marked as PCIe-only devices.

3) megasas-base

Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.

"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

QEMU with the pcie-pci-bridge device crashes if the guest board doesn't support MSI,

This is caused by wrong pcie-pci-bridge instantiation error handling. This patch fixes this issue
by falling back to legacy INTx if MSI is not available.
Also set the bridge's 'msi' property default value to 'auto' in order to trigger errors
only when user explicitly set msi=on.

226263fb5c hw/pci: add QEMU-specific PCI capability to the Generic PCI Express Root Port
To enable hotplugging of a newly created pcie-pci-bridge,
we need to tell firmware (e.g. SeaBIOS) to reserve
additional buses or IO/MEM/PREF space for pcie-root-port.
Additional bus reservation allows us to hotplug pcie-pci-bridge into this root port.
The number of buses and IO/MEM/PREF space to reserve are provided to the device via
a corresponding property, and to the firmware via new PCI capability.
The properties' default values are -1 to keep default behavior unchanged.

This reverts commit dc0ae76770.

Disabling the shpc controller has an undesired side effect.
The PCI bridge remains with no attached devices at boot time,
and the guest operating systems do not allocate any resources
for it, leaving the bridge unusable. Note that the behaviour
is dictated by the pci bridge specification.

Revert the commit and leave the shpc controller even if is not
actually used by any architecture. Slot 0 remains unusable at boot time.

e90f2a8c3e qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatable
cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.

When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.

Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.

Except for code comments, changes were generated using the
following Coccinelle patch:

5459ef3bff ppc patch queue 2017-02-02
This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.
 
 This is a long overdue ppc pull request for qemu-2.9.  It's been a
 long time coming due to some holidays and inconveniently timed
 problems with testing.  So, there's a lot in here:
 
     * More POWER9 instruction implementations for TCG
     * The simpler parts of my CPU compatibility mode cleanup
         * This changes behaviour to prefer compatibility modes over
           "raW" mode for new machine type versions
     * New "40p" machine type which is essentially a modernized and
       cleaned up "prep".  The intention is that it will replace "prep"
       once it has some more testing and polish.
     * Add pseries-2.9 machine type
     * Implement H_SIGNAL_SYS_RESET hypercall
     * Consolidate the two alternate CPU init paths in pseries by
       making it always go through CPU core objects to initialize CPU
     * A number of bugfixes and cleanups
     * Stop the guest timebase when the guest is stopped under KVM.
       This makes the guest system clock also stop when paused, which
       matches the x86 behaviour.
     * Some preliminary cleanups leading towards implementation of the
       POWER9 MMU.
 
 There are also some changes not strictly related to ppc code, but for
 its benefit:
 
     * Limit the pxi-expander-bridge (PXB) device to x86 guests only
       (it's essentially a hack to work around historical x86
       limitations)
     * Some additions to the 128-bit math in host_utils, necessary for
       some of the new instructions.
     * Revise a number of qtests and enable them for ppc

Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.9-20170202' into staging

ppc patch queue 2017-02-02

This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.

This is a long overdue ppc pull request for qemu-2.9.  It's been a
long time coming due to some holidays and inconveniently timed
problems with testing.  So, there's a lot in here:

    * More POWER9 instruction implementations for TCG
    * The simpler parts of my CPU compatibility mode cleanup
        * This changes behaviour to prefer compatibility modes over
          "raW" mode for new machine type versions
    * New "40p" machine type which is essentially a modernized and
      cleaned up "prep".  The intention is that it will replace "prep"
      once it has some more testing and polish.
    * Add pseries-2.9 machine type
    * Implement H_SIGNAL_SYS_RESET hypercall
    * Consolidate the two alternate CPU init paths in pseries by
      making it always go through CPU core objects to initialize CPU
    * A number of bugfixes and cleanups
    * Stop the guest timebase when the guest is stopped under KVM.
      This makes the guest system clock also stop when paused, which
      matches the x86 behaviour.
    * Some preliminary cleanups leading towards implementation of the
      POWER9 MMU.

There are also some changes not strictly related to ppc code, but for
its benefit:

    * Limit the pxi-expander-bridge (PXB) device to x86 guests only
      (it's essentially a hack to work around historical x86
      limitations)
    * Some additions to the 128-bit math in host_utils, necessary for
      some of the new instructions.
    * Revise a number of qtests and enable them for ppc

dc0ae76770 hw/pci: disable pci-bridge's shpc by default
The shpc component is optional while  ACPI hotplug is used
for hot-plugging PCI devices into a PCI-PCI bridge.
Disabling the shpc by default will make slot 0 usable at boot time
and not only for hot-plug, without loosing any functionality.
Older machines will have shpc enabled for compatibility reasons.
