Currently, the value of the page tables' address is hard-coded in the
ResetVector. This patch replaces these values with a PCD dependency.
A check for the size has been added to alert the developer to rewrite
the ASM according to the new size, if it has been changed.

In one of the next patches, we'll introduce ARRAY_SIZE in
"MdePkg/Include/Base.h". In order to proceed in small steps, make the
module-local definition of ARRAY_SIZE conditional. This way the
introduction of the macro under MdePkg will silently switch this module
over (after which we can remove the module-local definition completely).

XenConsoleSerialPortLib is a BASE type library instance, without being
restricted to UEFI client modules. (For example, the
"ArmVirtPkg/ArmVirtXen.dsc" platform builds this library instance into
"ArmVirtPkg/PrePi/ArmVirtPrePiUniCoreRelocatable.inf", which is a SEC type
module.) For such library instances, including <Uefi/UefiBaseType.h> is

In commit 5b2291f9567a ("OvmfPkg: QemuVideoDxe uses
MdeModulePkg/FrameBufferLib"), QemuVideoDxe was rebased to
FrameBufferBltLib.
The FrameBufferBltLib instance added in commit b1ca386074bd
("MdeModulePkg: Add FrameBufferBltLib library instance") logs many
messages on the VERBOSE level; for example, a normal boot with OVMF can
produce 500+ "VideoFill" messages, dependent on the progress bar, when the
VERBOSE bit is set in PcdDebugPrintErrorLevel. While FrameBufferBltLib is
certainly allowed to log such messages on the VERBOSE level, we should
separate those frequent messages from the (infrequent) ones produced by
QemuVideoDxe itself.
QemuVideoDxe logs VERBOSE messages in three locations (in two functions)
at the moment. All of them are infrequent: both QemuVideoBochsModeSetup()
and InstallVbeShim() are called from QemuVideoControllerDriverStart(),
that is, when a device is bound. Upgrade these messages to INFO level, so
that VERBOSE can be disabled in PcdDebugPrintErrorLevel -- perhaps
selectively for OvmfPkg/QemuVideoDxe -- without hiding these infrequent
messages.

Translating QEMU's virtio-block OpenFirmware device path to a UEFI device
path prefix was one of the earliest case handled in QemuBootOrderLib. At
that time, I terminated the translation output (the UEFI devpath prefix)
with a "/HD(" suffix.
The intent was for the translation to prefix-match only boot options with
HD() device path nodes in them, that is, no auto-generated "device level"
boot options. This was motivated by prioritizing specific boot options
created by OS installers over auto-generated "device level" options.
However, practice has shown that:
- OS installers place their installed boot options first in the boot order
anyway,
- other device types (SATA disks, virtio-scsi disks), where "/HD(" is not
appended, work just fine,
- requiring "/HD(" actually causes problems: after the OS-installed
specific boot option has been lost (or purposely removed), the
auto-generated "device level" boot option does the right thing (see the
Default Boot Behavior under
<http://blog.uncooperative.org/blog/2014/02/06/the-efi-system-partition/>).
The "/HD(" requirement causes such boot options to be dropped, which
prevents "fallback.efi" from running.
Relax the matching by removing the "/HD(" suffix from the translated
prefix.

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.

stdvga variant") as console.
ArmVirtPkg's PlatformBootManagerLib already filters with IS_PCI_DISPLAY();
see IsPciDisplay().

Commit 9399f68ae359 ("OvmfPkg: Virtio10Dxe: non-transitional driver for
virtio-1.0 PCI devices") created a "competition" between Virtio10Dxe and
QemuVideoDxe for virtio-vga devices. The binding order between these
drivers is unspecified, and the wrong order effectively breaks commit
94210dc95e9f ("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 94210dc95e9f ("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().)

In the Platform Init v1.4a spec,
- Volume 1 "4.7 Status Code Service" defines the
EFI_PEI_SERVICES.ReportStatusCode() service,
- Volume 1 "6.3.5 Status Code PPI (Optional)" defines the
EFI_PEI_PROGRESS_CODE_PPI (equivalent to the above),
- Volume 2 "14.2 Status Code Runtime Protocol" defines the
EFI_STATUS_CODE_PROTOCOL.
These allow PEIMs and DXE (and later) modules to report status codes.
Currently OvmfPkg uses modules from under
"IntelFrameworkModulePkg/Universal/StatusCode/", which produce the above
abstractions (PPI and PROTOCOL) directly, and write the status codes, as
they are reported, to the serial port or to a memory buffer. This is
called "handling" the status codes.
In the Platform Init v1.4a spec,
- Volume 3 "7.2.2 Report Status Code Handler PPI" defines
EFI_PEI_RSC_HANDLER_PPI,
- Volume 3 "7.2.1 Report Status Code Handler Protocol" defines
EFI_RSC_HANDLER_PROTOCOL.
These allow several PEIMs and runtime DXE drivers to register callbacks
for status code handling.
MdeModulePkg offers a PEIM under
"MdeModulePkg/Universal/ReportStatusCodeRouter/Pei" that produces both
EFI_PEI_PROGRESS_CODE_PPI and EFI_PEI_RSC_HANDLER_PPI, and a runtime DXE
driver under "MdeModulePkg/Universal/ReportStatusCodeRouter/RuntimeDxe"
that produces both EFI_STATUS_CODE_PROTOCOL and EFI_RSC_HANDLER_PROTOCOL.
MdeModulePkg also offers status code handler modules under
MdeModulePkg/Universal/StatusCodeHandler/ that depend on
EFI_PEI_RSC_HANDLER_PPI and EFI_RSC_HANDLER_PROTOCOL, respectively.
The StatusCodeHandler modules register themselves with
ReportStatusCodeRouter through EFI_PEI_RSC_HANDLER_PPI /
EFI_RSC_HANDLER_PROTOCOL. When another module reports a status code
through EFI_PEI_PROGRESS_CODE_PPI / EFI_STATUS_CODE_PROTOCOL, it reaches
the phase-matching ReportStatusCodeRouter module first, which in turn
passes the status code to the pre-registered, phase-matching
StatusCodeHandler module.
The status code handling in the StatusCodeHandler modules is identical to
the one currently provided by the IntelFrameworkModulePkg modules. Replace
the IntelFrameworkModulePkg modules with the MdeModulePkg ones, so we can
decrease our dependency on IntelFrameworkModulePkg.
