Laszlo Ersek 48ea3dedc5 hw/pci-bridge: format special OFW unit address for PXB host
We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg
file should follow the pattern

  /pci@i0cf8,%x/...

for devices that live behind an extra root bus. The extra root bus in
question is the %x'th among the extra root buses. (In other words, %x
gives the position of the affected extra root bus relative to the other
extra root buses, in bus_nr order.) %x starts at 1, and is formatted in
hex.

The portion of the unit address that comes before the comma is dynamically
taken from the main host bridge, similarly to sysbus_get_fw_dev_path().

Laszlo Ersek d10dda2d60 hw/pci-bridge: disable SHPC in PXB
OVMF downloads the ACPI linker/loader script from QEMU when the edk2 PCI
Bus driver globally signals the firmware that PCI enumeration and resource
allocation have completed. At this point QEMU regenerates the ACPI payload
in an fw_cfg read callback, and this is when the PXB's _CRS gets
populated.

Unfortunately, when this happens, the PCI_COMMAND_MEMORY bit is clear in
the root bus's command register, *unlike* under SeaBIOS. The consequences
unfold as follows:

- When build_crs() fetches dev->io_regions[i].addr, it is all-bits-one,
  because pci_update_mappings() --> pci_bar_address() calculated it as
  PCI_BAR_UNMAPPED, due to the PCI_COMMAND_MEMORY bit being clear.

- Consequently, the SHPC MMIO BAR (bar 0) of the bridge is not added to
  the _CRS, *despite* having been programmed in PCI config space.

- Similarly, the SHPC MMIO BAR of the PXB is not removed from the main
  root bus's DWordMemory descriptor.

- Guest OSes (Linux and Windows alike) notice the pre-programmed SHPC BAR
  within the PXB's config space, and notice that it conflicts with the
  main root bus's memory resource descriptors. Linux reports

  pci 0000:04:00.0: BAR 0: can't assign mem (size 0x100)
  pci 0000:04:00.0: BAR 0: trying firmware assignment [mem
                           0x88200000-0x882000ff 64bit]
  pci 0000:04:00.0: BAR 0: [mem 0x88200000-0x882000ff 64bit] conflicts
                           with PCI Bus 0000:00 [mem
                           0x88200000-0xfebfffff]

  While Windows Server 2012 R2 reports

    https://technet.microsoft.com/en-us/library/cc732199%28v=ws.10%29.aspx

    This device cannot find enough free resources that it can use. If you
    want to use this device, you will need to disable one of the other
    devices on this system. (Code 12)

This issue was apparently encountered earlier, see the "hack" in:

  https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02983.html

and the current hole-punching logic in build_crs() and build_ssdt() is
probably supposed to remedy exactly that problem -- however, for OVMF they
don't work, because at the end of the PCI enumeration and resource
allocation, which cues the ACPI linker/loader client, the command register
is clear.

The "shpc" property of "pci-bridge", introduced in the previous patches,
allows us to disable the standard hotplug controller cleanly, eliminating
the SHPC bar and the conflict.

Laszlo Ersek 4e5c9bfecf hw/pci-bridge: introduce "shpc" property
In the PCI expander bridge, we will want to disable those features of
pci-bridge that relate to SHPC (standard hotplug controller):

- SHPC bar and underlying MemoryRegion
- interrupt (INTx or MSI)
- effective hotplug callbacks
- other SHPC hooks (initialization, cleanup, migration etc)

Introduce a new feature request bit in the PCIBridgeDev.flags field, and
turn off the above if the bit is explicitly cleared.

Marcel Apfelbaum 40d14bef80 hw/pci: introduce PCI Expander Bridge (PXB)
PXB is a "light-weight" host bridge whose purpose is to enable
the main host bridge to support multiple PCI root buses
for pc machines.

As oposed to PCI-2-PCI bridge's secondary bus, PXB's bus
is a primary bus and can be associated with a NUMA node
(different from the main host bridge) allowing the guest OS
to recognize the proximity of a pass-through device to
other resources as RAM and CPUs.

The PXB is composed from:
 - A primary PCI bus (can be associated with a NUMA node)
   Acts like a normal pci bus and from the functionality point
   of view is an "expansion" of the bus behind the
   main host bridge.
 - A pci-2-pci bridge behind the primary PCI bus where the actual
   devices will be attached.
 - A host-bridge PCI device
   Situated on the bus behind the main host bridge, allows
   the BIOS to configure the bus number and IO/mem resources.
   It does not have its own config/data register for configuration
   cycles, this being handled by the main host bridge.
-  A host-bridge sysbus to comply with QEMU current design.

David Gibson 4681867544 Add specific config options for PCI-E bridges
The i82801b11, ioh3420 and xio3130 PCI Express devices are currently
included in the build unconditionally.

While they could theoretically appear on any target platform with PCI-E,
they're pretty unlikely to appear on platforms that aren't Intel derived.

Therefore, to avoid presenting unlikely-to-be-relevant devices to the user,
add config options to enable these components, and enable them by default
only on x86 and arm platforms.

(Note that this patch does include these for aarch64, via its inclusion of
arm-softmmu.mak).

Markus Armbruster 08c58f92f6 pci-host: Consistently set cannot_instantiate_with_device_add_yet

You need both for the thing to work.  Arguably, these bridges should
be modelled as a single, composite devices instead of pairs of
seemingly independent devices you can only use together, but we're not
there, yet.

Since the sysbus part can't be instantiated with device_add, yet,
permitting it with the PCI part is useless.  We shouldn't offer
useless options to the user, so let's set
cannot_instantiate_with_device_add_yet for them.
