2015-07-14OvmfPkg: QemuBootOrderLib: recognize extra PCI root busesLaszlo Ersek
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.

2015-07-14OvmfPkg: QemuBootOrderLib: introduce ExtraRootBusMapLaszlo Ersek
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.

2015-07-14OvmfPkg: PciHostBridgeDxe: look for all root busesLaszlo Ersek
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.

This field was supposed to store the number of root buses created; however we don't need to keep that count persistently. After the entry point returns, nothing reads this field.

2015-07-14OvmfPkg: PciHostBridgeDxe: use private buffer in RootBridgeIoConfiguration()Laszlo Ersek
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.

2015-07-14OvmfPkg: PciHostBridgeDxe: release resources on driver entry failureLaszlo Ersek
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.

2015-07-14OvmfPkg: PciHostBridgeDxe: embed device path in private root bridge structLaszlo Ersek
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".

2015-07-14OvmfPkg: PciHostBridgeDxe: eliminate nominal support for multiple host bridgesLaszlo Ersek
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".

2015-07-14OvmfPkg: PlatformBdsLib: refine PCI host bridge assertionLaszlo Ersek
The ASSERT() in SetPciIntLine() assumes that Device 0 on "the" root bus corresponds to the PCI host bridge (00:00). This used to be true, but 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 number explicitly.
