96a8821d21 ("virtio: unbreak virtio-pci with IOMMU after caching ring
translations") tries to make IOMMU works with virtio memory region
cache, but it requires IOMMU to be created before any virtio
devices. This is sub optimal, fixing this by introduce a bus master
container to make sure address space can be initialized during device
registering, and then we can safely set alias and make
bus_master_enable_region as its subregion during bus master

This behaviour change is not actually a bug since no assumptions should be
made on DT ordering. But it has no real justification either, other than
being the consequence of the way fdt_add_subnode() inserts new elements
to the front of the FDT rather than adding them to the tail.
This patch reverts to the historical SLOF ordering by walking PCI devices
in reverse order. This reconciles pseries with x86 machine types behavior.
It is expected to make things easier when porting existing applications to
power.

over time. Specifically,
commit b2101eae63 ("pcie: Set the "link

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.

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.

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.

It seems to make sense to import pci_regs.h from linux:
why maintain our own?
As a first step, move the header to standard-headers,
and add it to the update script.

Fix pba_offset initialization value for Chelsio T5 Virtual Function
device. The T5 hardware has a bug in it where it reports a Pending Interrupt
Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead
of the 0x1000 that the hardware actually uses internally. As the hardware
doesn't return the correct pba_offset value, add a quirk to instead
return a hardcoded value of 0x1000 when a Chelsio T5 VF device is
detected.
This bug has been fixed in the Chelsio's next chip series T6 but there are
no plans to respin the T5 ASIC for this bug. It is just documented in the
T5 Errata and left it at that.

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.
