Laszlo Ersek 4fc18df913 OvmfPkg: QemuBootOrderLib: recognize extra PCI root buses
The OFW device path that QEMU exports in the "bootorder" fw_cfg file, for
a device that is plugged into the main PCI root bus, is:

  /pci@i0cf8/...

Whereas the same device plugged into the N'th extra root bus results in:

  /pci@i0cf8,N/pci-bridge@0/...

(N is in hex.)

Extend TranslatePciOfwNodes() so that it not assume a single PCI root;
instead it parse the extra root bus serial number if present, and resolve
it in the translation to the UEFI devpath fragment.

Note that the "pci-bridge@0" node is a characteristic of QEMU's PXB
device. It reflects the actual emulated PCI hierarchy. We don't parse it
specifically in this patch, because it is automatically handled by the
bridge sequence translator added recently in SVN rev 17385 (git commit
feca17fa4b) -- "OvmfPkg: QemuBootOrderLib: parse OFW device path nodes of
PCI bridges".

The macro EXAMINED_OFW_NODES need not be raised from 6. The longest OFW
device paths that we wish to recognize under this new scheme comprise 5
nodes. The initial "extra root bus" OFW fragment, visible at the top,
takes up 2 nodes, after which the longest device-specific patterns (IDE
disk, IDE CD-ROM, ISA floppy, virtio-scsi disk) take 3 more nodes each.

Laszlo Ersek 5eb0b80afc OvmfPkg: QemuBootOrderLib: introduce ExtraRootBusMap
SeaBIOS requires the OpenFirmware device paths exported in the "bootorder"
fw-cfg file to refer to extra (PXB) root buses by their relative positions
(in increasing bus number order) rather than by actual bus numbers.

However, OVMF's PCI host bridge / root bridge driver creates PciRoot(UID)
device path nodes for extra PCI root buses with UID=bus_nr, not position.
(These ACPI devpath UID values must, and do, match the UID values exposed
in QEMU's ACPI payload, generated for PXB root buses.)

Therefore the boot order matching logic will have to map extra root bus
positions to bus numbers. Add a small group of utility functions to help
with that.

Laszlo Ersek 68306ac2f2 OvmfPkg: PciHostBridgeDxe: shorten search for extra root buses
QEMU provides an fw_cfg file called "etc/extra-pci-roots", containing a
little-endian UINT64 value that exposes the number of extra root buses. We
can use this value to terminate the scan as soon as we find the last extra
root bus.

Laszlo Ersek bdb1c98f03 OvmfPkg: PciHostBridgeDxe: look for all root buses
In this patch we assume that root bus number 0 is always there (same as
before), and scan the rest of the extra root buses, up to and including
255. When an extra root bus is found, we install the PCI root bridge IO
protocol for the previous root bus (which might be bus 0 or just the
previous extra root bus).

The root bridge protocol created thus will report the available bus number
range

  [own bus number, next extra root bus number - 1]

The LHS of this interval will be used for the root bus's own number, and
the rest of the interval (which might encompass 0 additional elements too)
can be used by the PCI bus driver to assign subordinate bus numbers from.

(Subordinate buses are provided by PCI bridges that hang off the root bus
in question.)

For MMIO and IO space allocation, all the root buses share the original
[0x8000_0000, 0xFFFF_FFFF] and [0x0, 0xFFFF] ranges, respectively.

Laszlo Ersek 20f7840e3f OvmfPkg: PciHostBridgeDxe: use private buffer in RootBridgeIoConfiguration()
On output, the EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Configuration() function
produces a pointer to a buffer of ACPI 2.0 resource descriptors:

  Resources  A pointer to the ACPI 2.0 resource descriptors that describe
             the current configuration of this PCI root bridge. The
             storage for the ACPI 2.0 resource descriptors is allocated by
             this function. The caller must treat the return buffer as
             read-only data, and the buffer must not be freed by the
             caller.

PciHostBridgeDxe currently provides this buffer in a structure with static
storage duration. If multiple root bridges existed in parallel, the
pointers returned by their Configuration() methods would point to the same
static storage. A later Configuration() call would overwrite the storage
pointed out by an earlier Configuration() call (which was possibly made
for a different, but still alive, root bridge.)

Fix this problem by embedding the configuration buffer in
PCI_ROOT_BRIDGE_INSTANCE.

While we're at it, correct some typos (Desp -> Desc), spell out a missing
pack(1) pragma, and improve formatting.

Laszlo Ersek 7ee9dc2321 OvmfPkg: PciHostBridgeDxe: release resources on driver entry failure
The entry point of the driver, InitializePciHostBridge(), leaks resources
(and installed protocols) in the following cases:

- The first root bridge protocol installation fails. In this case, the
  host bridge protocol is left installed, but the driver exits with an
  error.

- The second or a later root bridge protocol installation fails. In this
  case, the host bridge protocol, and all prior root bridge protocols, are
  left installed, even though the driver exits with an error.

Handle errors correctly: roll back / release / uninstall resources when
aborting the driver.

Laszlo Ersek fe907a688c OvmfPkg: PciHostBridgeDxe: embed device path in private root bridge struct
Currently we define a device path for each root bridge statically (for all
one of them). Since we'll want to create a dynamic number of root bridges,
replace the static device paths with a common template, embed the actual
device path into the private root bridge structure, and distinguish the
device paths from each other in the UID field (as required by ACPI).

This patch is best viewed with "git show -b".

Laszlo Ersek 7f66476701 OvmfPkg: PciHostBridgeDxe: eliminate nominal support for multiple host bridges
The entry point function of this driver, InitializePciHostBridge(), and
the static storage duration objects it relies on, are speculatively
generic -- they nominally support more than one host bridges, but (a) the
code hardwires the number of host bridges as 1, (b) it's very unlikely
that we'd ever like to raise that number (especially by open-coding it).

So let's just remove the the nominal support, and simplify the code.

This patch is best viewed with "git show -b".

because we're going to have extra root buses (with nonzero bus numbers),
soon this assumption may no longer hold. Check for the zero root bus
