Support multiple PCI segment for PCI_CONFIG2 opcodes.
PiDxeS3BootScriptLib needs to be updated to consume PciSegmentLib
instead of PciLib. That means platforms need to add PciSegmentLib
declaration like below in platform dsc if the PciSegmentLib was
not declared in platform dsc before.
PciSegmentLib|MdePkg/Library/BasePciSegmentLibPci/BasePciSegmentLibPci.inf
For platforms only have one segment,
MdePkg/Library/BasePciSegmentLibPci/BasePciSegmentLibPci.inf is recommended
to be used and declared in platform dsc for PiDxeS3BootScriptLib to have
equivalent functionality with before.

Setting the linux,pci-probe-only was intended to align OSes booting via
DT with OSes booting via ACPI in the way they honor the PCI configuration
performed by the firmware. However, ACPI on arm64 does not currently honor
the firmware's PCI configuration, and the linux,pci-probe-only completely
prevents any PCI reconfiguration from occurring under the OS, including
what is needed to support PCI hotplug.
Since the primary use case was OS access to the GOP framebuffer (which
breaks when the framebuffer BAR is moved when the OS reconfigures the
PCI), we can undo this change now that ArmVirtQemu has moved to a GOP
implementation that does not expose a raw framebuffer in the first place.
This effectively reverts commit 8b816c624d ("ArmVirtPkg/VirtFdtDxe: set
/chosen/linux,pci-probe-only to 1 in DTB")

The prototypes of EbcInterpret() and ExecuteEbcImageEntryPoint() are

For ExecuteEbcImageEntryPoint(), this involves passing the EntryPoint

us to do a tail call. For EbcInterpret(), instead of copying each

another copy is made into the VM stack), pass a pointer to the

This patch adds the skeleton of the driver: it implements the Component
Name 2 Protocol and the Driver Binding Protocol, in accordance with the
generic and GOP-specific requirements set forth in the UEFI spec and the
Driver Writers' Guide.
The basic idea is that VGPU_DEV abstracts the virtio GPU device, while the
single VGPU_GOP that we intend to support at this point stands for "head"
(aka "scanout") #0.
For now, the Virtio Device Protocol is only used for driver binding; no
actual virtio operations are done yet. Similarly, we use a "dummy" GOP
GUID and protocol structure (a plain UINT8 object) for now, so that
GOP-consuming drivers don't look at what we produce just yet.
The driver is a bit different from the other virtio device drivers written
thus far:
- It implements the GetControllerName() member of the Component Name 2
Protocol. (Formatting helpful names is recommended by UEFI.) As a "best
effort", we format the PCI BDF into the name (a PCI backend is not
guaranteed by VIRTIO_DEVICE_PROTOCOL). It should provide a more friendly
experience in the shell and elsewhere.
- This driver seeks to support all RemainingDevicePath cases:
- NULL: produce all (= one) child handles (= VGPU_GOP heads) at once,
- End of Device Path Node: produce no child handles,
- specific ACPI ADR Node: check if it's supportable, and produce it
(only one specific child controller is supported).
This is one of the reasons for separating VGPU_GOP from VGPU_DEV.
The driver is a hybrid driver: it produces both child handles (one, to be
exact), but also installs a structure (VGPU_DEV) directly on the VirtIo
controller handle, using gEfiCallerIdGuid as protocol GUID. This is a
trick I've seen elsewhere in edk2 (for example, TerminalDxe), and it is
necessary for the following reason:
In EFI_COMPONENT_NAME2_PROTOCOL.GetControllerName(), we must be able to
"cast down" a VirtIo ControllerHandle to our own private data structure
(VGPU_DEV). That's only possible if we install the structure directly on
the VirtIo ControllerHandle (thereby rendering the driver a hybrid
driver), because a child controller with our GOP implementation on it may
not exist / be passed in there.

Commit 9399f68ae3 ("OvmfPkg: Virtio10Dxe: non-transitional driver for

QemuVideoDxe for virtio-vga devices. The binding order between these
drivers is unspecified, and the wrong order effectively breaks commit
94210dc95e ("OvmfPkg: QemuVideoDxe: add virtio-vga support").
Thus, never bind virtio-vga in Virtio10Dxe; QemuVideoDxe provides better
compatibility for guest OSes that insist on inheriting a linear
framebuffer. Users who prefer the VirtIo GPU interface at boot time should
specify virtio-gpu-pci, which is exactly virtio-vga, minus the VGA
compatibility (such as the framebuffer).

The PCI (Vendor ID, Device ID) pair (0x1af4, 0x1050) stands for both the
virtio-vga and the virtio-gpu-pci device models of QEMU. They differ in
two things:
- the former has a VGA-compatibility linear framebuffer on top of the
latter,
- the former has PCI_CLASS_DISPLAY_VGA device class, while the latter has
PCI_CLASS_DISPLAY_OTHER.
In commit 94210dc95e ("OvmfPkg: QemuVideoDxe: add virtio-vga support"),
we enabled QemuVideoDxe to drive virtio-vga simply by adding its (Vendor
ID, Device ID) pair to gQemuVideoCardList. This change inadvertently
allowed QemuVideoDxe to bind virtio-gpu-pci, which it cannot drive though.
Restrict QemuVideoDxe to PCI_CLASS_DISPLAY_VGA, in order to exclude
virtio-gpu-pci. For the other cards that QemuVideoDxe drives, this makes
no difference. (Note that OvmfPkg's PlatformBootManagerLib instance has
always only added PCI_CLASS_DISPLAY_VGA devices to ConOut; see
DetectAndPreparePlatformPciDevicePath().)
