Zeng, Star fea55a1661 MdeModulePkg: INF/DEC file updates to EDK II packages
2. Add MODULE_UNI_FILE file that contains the localized Abstract and Description of a module.
a. Addresses an information gap between INF files and the UEFI Distribution Packaging Specification XML schema
b. There will be an associated update to UPT in BaseTools to consume MODULE_UNI_FILE and associated UNI file during UDP creation that performs the INF -> XML conversion.
c. There will be an associated update to UPT in BaseTools to produce MODULE_UNI_FILE and associated UNI file during UDP installation that performs the XML -> INF conversion.

3. Add Module Extra UNI file that provides the localized Name of a module.
a. [UserExtensions.TianoCore."ExtraFiles"] provides an easy method for a module to specify extra files not listed in [Sources] or [Binaries] sections to be added to a UDP without having to list the files in the UPT package information data file.
b. There will be an associated update to UPT in BaseTools to package up files listed in [UserExtensions.TianoCore."ExtraFiles"] during UDP creation.
c. UNI file contains localized name of a module to go along with the localized Abstract and Description from the MODULE_UNI_FILE.

Alex Williamson b0bc24aff5 The following call tree exposes a bug in the lifetime (ie. too late
creation) of PciIoDevice->DevicePath. The bug can be triggered when
PciBusDxe is built into OVMF, with qemu/KVM device assignment of
a PCI-express device on the default 440FX machine type.  OVMF
correctly discovers that the device is PCIe and begins probing
extended configuration space for the device.  The root bridge
has no way to access extended config space and correctly errors,
sending us into the error reporting chain seen below.  It's
possible that this error path could also be reproduced on physical
hardware when a PCI-to-PCIe bridge is present.

In English:
- CreatePciIoDevice() allocates a zeroed out PCI_IO_DEVICE structure.
- PciIoConfigRead() tries to access the (extended) config space, and
  fails.
- PciIoConfigRead() wants to report a status code (read error) for the
  device path.
- Unfortuantely, PciIoDevice->DevicePath is still NULL at that point.
- The ASSERT() in ReportStatusCodeWithDevicePath() fires.

Fix it by moving CreatePciDevicePath() into CreatePciIoDevice(),
allowing PciIoDevice->DevicePath to be initialized before we
begin probing the device capabilities:

Wei Liu 5624a27dde MdeModulePkg: introduce PcdPciDisableBusEnumeration
Platforms such as Xen already enumerates PCI bridges and devices. Use
this PCD to control EDK2 behavior.

PcdPciDisableBusEnumeration is placed under [PcdsFixedAtBuild,
PcdsPatchableInModule, PcdsDynamic, PcdsDynamicEx], so that it is
possible to alter it during runtime.

The default setting of this PCD is false (allow full PCI enumeration) to
preserve the same behavior before this change.

rsun3 e0ee9d9314 Clean ISA_IO/ISA_IO_16 and VGA_IO/VGA_IO_16 attribute usage in PCI bus driver/PCI host bridge drivers/LPC/VGA device drivers.
1. Fix the incorrect definition of EFI_PCI_IO_ATTRIBUTE_VGA_IO_16 (does not conform to the UEFI spec) in PciIo.h.
2. Add missing definitions of ISA and VGA IO attributes in PCI Root Bridge IO protocol.
3. Improve the algorithm in the PCI bus driver to get PCI platform policy from PCI Platform Protocol and PCI Override Protocol.
4. Update the PCI bus driver to use the PCI platform policy to determine the supported attributes that are returned by the EFI_PCI_IO_PROTOCOL.Attributes() function. This is required by the PI spec.
5. Add a backward compatibility workaround for PCI VGA drivers in Option ROM, which typically sets VGA_IO without checking supported attributes.
6. Update the PCI host bridge driver in PcAtChipsetPkg to report VGA_IO_16 and ISA_IO_16 instead of VGA_IO/ISA_IO attributes. Modern chipsets don’t have hardware capability to control 10-bit or 16-bit decoding for ISA/VGA aliases.
7. Update LPC/VGA device drivers to check supported attributes of VGA_IO/VGA_IO_16 or ISA_IO/ISA_IO_16.

rsun3 7afa5ea800 Add special treatment for EFI_PCI_IO_ATTRIBUTE_EMBEDDED_DEVICE and EFI_PCI_IO_ATTRIBUTE_EMBEDDED_ROM, because these attributes are only for PCI IO, while not supported by PCI Root Bridge IO.

rsun3 4ed4e19c08 Update the PCI bus driver to correctly set the EFI_PCI_IO_ATTRIBUTE_EMBEDDED_ROM attribute of PCI IO. Per UEFI spec, this attribute is used to determine if the ROM image is from the ROM BAR or from a platform specific location.

rsun3 55565b0859 The PCI HotPlug Init Protocol returns a list of Root HPC, but it is possible that some HPCs in the list are not found during PCI enumeration. In this case, the PCI HotPlug Init Protocol.InitializeRootHpc() will not be called for the un-found HPCs. However, in AllRootHPCInitialized(), all reported HPCs are checked to see if it has been initialized, so TIME_OUT happens.
This check-in fix the issue by adding a flag to indicate if a HPC is found during PCI enumeration or not. This check-in also adds a debug message if any found HPC failed with initialization.

rsun3 aeeb84bab4 Some existing PCI adapters with UEFI option ROMs make unaligned requests through the PCI I/O Protocol. Add support for unaligned requests in the PCI IO protocol implementation in the PCI Bus driver to be compatible with those UEFI option ROMs.
This solution defines a PCD Feature Flag to enabled support for unaligned requests through the PCI I/O Protocol.  This flag is disabled by default. Platforms that do want to support such EFI/UEFI drivers that make unaligned PCI I/O requests should enable this feature.

rsun3 13fd0d50b5 Per the UEFI spec, if a PCI controller is a P2P bridge, then the I/O, Memory and Bus Master bits in the Command register of the PCI configuration header should be placed in the enabled state by the PCI Bus driver.
But current PCI bus driver has a bug that if a P2P bridge has no child devices detected during enumeration, the bits won’t be set. This may impact PCI hot plug capable bridges because the OS may re-assign resources for them causing the reserved resource by the firmware will be overwritten.

with a member of the same enum type.

rsun3 d40483911c Fix bugs in the PCI bus driver to support SR-IOV.
1. Expand the type of Offset in the _PCI_BAR structure from UINT8 to UINT16, because a VF BAR’s offset may be >= 0x100;
2. Enable ARI Capable Hierarchy for SR-IOV devices at earlier time because FirstVFOffset and VFStride of a SR-IOV device may change after its ARI Capable Hierarchy is set;
3. Change type of PcdSrIovSupport, PcdAriSupport, PcdMrIovSupport from FeatureFlag to [FixAtBuild, PcdDynamics], which allows SR-IOV/MR-IOV/ARI feature can be turn on/off dynamically, typically via a setup option.
4. Change PCI bus scan algorithm in PciScanBus() to prevent the case where some ARI extended functions may be skipped in the scan loop.

mdkinney 8063b47b1c Fix bug in PciHostBridgeEnumerator().
A linked list is created for the list of PCI Root Bridges in the platform.  This list is then traversed to enumerate each PCI Root Bridge.  After enumeration, the RootBridgeDev is destroyed, but it was not removed from the linked list before it was destroyed.  This left the linked list of PCI Root Bridges in a bad state, specially if memory is cleared on frees, or the freed buffer was reallocated.

The fix is to remove the node from the linked list before the RootBridgeDev is destroyed.
