Hao Wu 23a596db1b MdeModulePkg Ata: Use the new (incompatible) PortMultiplierPort semantics
The Mantis ticket 1353 <https://mantis.uefi.org/mantis/view.php?id=1353>
and Mantis ticket 1472 <https://mantis.uefi.org/mantis/view.php?id=1472>
updated the description of the port multiplier port number parameter in
SATA Device Path Node and ATA Pass-Through Protocol.

Now, this parameter should be set to 0xFFFF instead of 0 to indicate that
an ATA device is directly attached on the controller port.

Please note that this is an incompatible change. The consumer of SATA
device path or ATA_PASS_THRU needs to re-examine its usage to follow UEFI
2.5 mantis 1353 and 1472.

When the aperture base equals to aperture limit, the old code treats
the aperture as non-existent. It's not correct because it indicates
a range starting with base and the length is 1.
The new code corrects the comparing bug.

Laszlo Ersek ce1647fc60 MdeModulePkg: ScsiDiskDxe: cope with broken "Supported VPD Pages" VPD page
The USB flash drive with Vendor ID 0x1516 (CompUSA) and Product ID 0x6221
returns a broken "Supported VPD Pages" VPD page. In particular, the
PageLength field has the invalid value 0x0602 (decimal 1538).

This prevents the loop from terminating that scans for the Block Limits
VPD page code in ScsiDiskInquiryDevice():

        for (Index = 0; Index < PageLength; Index++) {

because the Index variable has type UINT8, and it wraps from 255 to 0,
without ever reaching PageLength (1538), and because
EFI_SCSI_PAGE_CODE_BLOCK_LIMITS_VPD does not occur at offsets 0 through
255.

* The fix is not to change the type of Index to UINT16 or a wider type.
  Namely, section

    7.8.14 Supported VPD Pages VPD page

  in the "SCSI Primary Commands - 4" (SPC-4) specification names the
  following requirement:

    The supported VPD page list shall contain a list of all VPD page codes
    (see 7.8) implemented by the logical unit in ascending order beginning
    with page code 00h.

  Since page codes are 8-bit unsigned quantities, it follows that the
  maximum size for the Supported VPD Pages VPD page is 0x100 bytes, in
  which every possible page code (0x00 through 0xFF) will be found, before
  the UINT8 offset wraps around.

  (EFI_SCSI_SUPPORTED_VPD_PAGES_VPD_PAGE.SupportedVpdPageList is correctly
  sized as well, in "MdePkg/Include/IndustryStandard/Scsi.h".)

* Instead, add sanity checks that enforce the above requirement. If the
  device breaks the spec, simply fall back to the "Block Limits page
  absent" case.

Ard Biesheuvel b59e2427c2 MdeModulePkg/PciBusDxe: don't create bogus descriptor if no resources needed
If the current PCI configuration requires no resources to be allocated at
all (i.e., unpopulated bus), the PCI enumeration code creates a single
ACPI_ADDRESS_SPACE_DESCRIPTOR memory descriptor with all fields cleared.
This is rejected by the SubmitResources() implementation of the generic
PciHostBridgeDxe in the following way:

  PciHostBridge: SubmitResources for PcieRoot(0x0)
   Mem: Granularity/SpecificFlag = 0 / 00
        Length/Alignment = 0x0 / 0x0
  PciBus: HostBridge->SubmitResources() - Invalid Parameter

  ASSERT_EFI_ERROR (Status = Invalid Parameter)
  ASSERT [PciBusDxe] .../PciBusDxe/PciLib.c(561): !EFI_ERROR (Status)

So instead, create the empty configuration as a single entry of type
EFI_ACPI_END_TAG_DESCRIPTOR.

Laszlo Ersek 014b472053 MdeModulePkg: PciHostBridgeDxe: don't assume extended config space
The "pc" ("pc-i440fx-*") machine types of QEMU don't support extended
config space. Accordingly, OVMF will use the following library instances
in connection with the core PciHostBridgeDxe driver:

  BasePciSegmentLibPci [class: PciSegmentLib]
    BasePciLibCf8      [class: PciLib]
      BasePciCf8Lib    [class: PciCf8Lib]

Add a new field to the PCI_ROOT_BRIDGE structure so that
RootBridgeIoCheckParameter() can catch config space offsets above 0xFF on
such old (emulated) platforms.

Ruiyu Ni 7b0a1ead7d MdeModuelPkg/PciBus: Return AddrTranslationOffset in GetBarAttributes
Some platform doesn't use CPU(HOST)/Device 1:1 mapping for PCI Bus.
But PCI IO doesn't have interface to tell caller (device driver)
whether the address returned by GetBarAttributes() is HOST address
or device address.
UEFI Spec 2.6 addresses this issue by clarifying the address returned
is HOST address and caller can use AddrTranslationOffset to calculate
the device address.

Ruiyu Ni 6474f1f156 MdeModulePkg/PciHostBridge: Don't assume resources are fully NonExistent
The patch removes the assumption that the resources claimed by root
bridges should not exist. Because resources might have been added:
1. by platform modules either in PEI through resource HOB, or in DXE,
   before the PCI host bridge driver runs.
2. Resources claimed by different root bridges may overlap so that
   resource adding operation for latter root bridges may fail if
   we assume the resource should not exist.

In real world, this patch is to fit OVMF platform needs because
different root bridges in OVMF platform shares the same resources.
