We changed link status register in pci express endpoint capability
over time. Specifically,
commit b2101eae63 ("pcie: Set the "link
active" in the link status register") set data link layer link active
bit in this register without adding compatibility to old machine types.
When migrating from qemu 2.3 and older this affects xhci devices which
under machine type 2.0 and older have a pci express endpoint capability
even if they are on a pci bus.
Add compatibility flags to make this bit value match what it was under
2.3.
Additionally, to avoid breaking migration from qemu 2.3 and up,
suppress checking link status during migration: this seems sane
since hardware can change link status at any time.

One more IEC notifier is added to let msi routes know about the IEC
changes. When interrupt invalidation happens, all registered msi routes
will be updated for all PCI devices.
Since both vfio and vhost are possible gsi route consumers, this patch
will go one step further to keep them safe in split irqchip mode and
when irqfd is enabled.

msi_init() reports errors with error_report(), which is wrong
when it's used in realize().
Fix by converting it to Error.
Fix its callers to handle failure instead of ignoring it.
For those callers who don't handle the failure, it might happen:
when user want msi on, but he doesn't get what he want because of
msi_init fails silently.

This fix SID verification failure when IOMMU IR is enabled with PCI
bridges. Existing pci_requester_id() is more like getting BDF info
only. Renaming it to pci_get_bdf(). Meanwhile, we provide the correct
implementation to get requester ID. VT-d spec 5.1.1 is a good reference
to go, though it talks only about interrupt delivery, the rule works
exactly the same for non-interrupt cases.
Currently, there are three use cases for pci_requester_id():
- PCIX status bits: here we need BDF only, not requester ID. Replacing
with pci_get_bdf().
- PCIe Error injection and MSI delivery: for both these cases, we are
looking for requester IDs. Here we should use the new impl.
To avoid a PCI walk every time we send MSI message, one requester_id
cache field is added to PCIDevice to cache the result when initialize
PCI device.

hw/pci/pci.h includes qemu-common.h, but its users only need pcibus_t

This adds the SAS1068 device, a SAS disk controller used in VMware that
is oldish but widely supported and has decent performance. Unlike
megasas, it presents itself as a SAS controller and not as a RAID
controller. The device corresponds to the mptsas kernel driver in
Linux.
A few small things in the device setup are based on Don Slutz's old
patch, but the device emulation was written from scratch based on Don's
SeaBIOS patch and on the FreeBSD and Linux drivers. It is 2400 lines
shorter than Don's patch (and roughly the same size as MegaSAS---also
because it doesn't support the similar SPI controller), implements SCSI
task management functions (with asynchronous cancellation), supports
big-endian hosts, has complete support for migration and follows the
QEMU coding standards much more closely.
To write the driver, I first split Don's patch in two parts, with
the configuration bits in one file and the rest in a separate file.
I first left mptconfig.c in place and rewrote the rest, then deleted
mptconfig.c as well. The configuration pages are still based mostly on
VirtualBox's, though not exactly the same. However, the implementation
is completely different. The contents of the pages themselves should
not be copyrightable.

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.

The mmcfg space is a memory region that allows access to PCI config space
in the PCIe world. To maintain abstraction layers, I would like to expose
the mmcfg space as a sysbus mmio region rather than have it mapped straight
into the system's memory address space though.
So this patch splits the initialization of the mmcfg space from the actual
mapping, allowing us to only have an mmfg memory region without the map.

This reverts commit a53ae8e934.
The patch being reverted introduced a low-priority memory region
covering all 64 bit pci address space. This exposed the following bugs
elsewhere in the code:
1. Some memory regions have INT64_MAX size, where the
intent was all 64 bit address space.
This results in a sub-page region, should be UINT64_MAX.
2. page table rendering in exec.c ignores physical address bits
above TARGET_PHYS_ADDR_SPACE_BITS.
Access outside this range (e.g. from device DMA, or gdb stub)
ends up with a wrong region. Registering a region outside this
range leads to page table corruption.
3. Some regions overlap PCI hole and have same priority.
This only works as long as no device uses the overlapping address.
It doesn't look like we can resolve all issues in time for 1.7.
Let's fix the bugs first and apply afterwards for 1.8.

A PCI device's DMA address space (possibly an IOMMU) is returned by a
method on the PCIBus. At the moment that only has one caller, so the
method is simply open coded. We'll need another caller for VFIO, so
this patch introduces a helper/wrapper function.
If IOMMU is not set, the pci_device_iommu_address_space() function
returns the parent's IOMMU skipping the "bus master" address space as
otherwise proper emulation would require more effort for no benefit.

The host_buses list is an odd structure - a list of pointers to PCI root
buses existing in parallel to the normal qdev tree structure. This patch
removes it, instead putting the link pointers into the PCIHostState
structure, which have a 1:1 relationship to PCIHostBus structures anyway.

At present, pci_nic_init() and pci_nic_init_nofail() assume that they will
only create a NIC under the primary PCI root. As we add support for
multiple PCI roots, that may no longer be the case. This patch adds a root
bus parameter to pci_nic_init() (and updates callers accordingly) to allow
the machine init code using it to specify the right PCI root for NICs
created by old-style -net nic parameters. NICs created new-style, with
-device can of course be put anywhere.

pci_get_bus_devfn() interprets a full PCI address string to give a PCIBus *
and device/function number within that bus. Currently it assumes it is
working on an address under the primary PCI root bus. This patch extends
it to allow the caller to specify a root bus. This might seem a little odd
since the supplied address can (theoretically) include a PCI domain number.
However, attempting to use a non-zero domain number there is currently an
error, so that shouldn't really cause problems.

pci_find_domain() is used in a number of places where we want an id for a
whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is
that many platforms may support multiple independent host bridges with no
hardware supplied notion of domain number.
This patch, therefore, replaces calls to pci_find_domain() with calls to
a new pci_root_bus_path() returning a string. The new call is implemented
in terms of a new callback in the host bridge class, so it can be defined
in some way that's well defined for the platform. When no callback is
available we fall back on the qbus name.
Most current uses of pci_find_domain() are for error or informational
messages, so the change in identifiers should be harmless. The exception
is pci_get_dev_path(), whose results form part of migration streams. To
maintain compatibility with old migration streams, the PIIX PCI host is
altered to always supply "0000" for this path, which matches the old domain
number (since the code didn't actually support domains other than 0).
For the pseries (spapr) PCI bridge we use a different platform-unique
identifier (pseries machines can routinely have dozens of PCI host
bridges). Theoretically that breaks migration streams, but given that we
don't yet have migration support for pseries, it doesn't matter.
Any other machines that have working migration support including PCI
devices will need to be updated to maintain migration stream compatibility.

Currently pci_find_domain() performs two functions - it locates the PCI
root bus above the given bus, then looks up that root bus's domain number.
This patch adds a helper function to perform the first task, finding the
root bus for a given PCI device. This is then used in pci_find_domain().
This changes pci_find_domain()'s signature slightly, taking a PCIDevice
instead of a PCIBus - since all callers passed something of the form
dev->bus, this simplifies things slightly.

pci_find_root_bus() takes a domain parameter. Currently PCI root buses
with domain other than 0 can't be created, so this is more or less a long
winded way of retrieving the main PCI root bus. Numbered domains don't
actually properly cover the (non x86) possibilities for multiple PCI root
buses, so this patch for now enforces the domain == 0 restriction in other
places to replace pci_find_root_bus() with an explicit
pci_find_primary_bus().
