yuchenlin 438ada5aa5 Revert "OvmfPkg/QemuVideoDxe: Helper functions for unaligned port I/O."
This reverts commit 05a5379458.

The VMWare SVGA display device implemented by Qemu (-vga vmware) uses
an I/O-type BAR which is laid out such that some register offsets are
not aligned to the read/write width with which they are expected to be
accessed. However, we reverted the initialization of VMWare SVGA device,
we don't need such unaligned I/O.

yuchenlin 98856a724c Revert "OvmfPkg/QemuVideoDxe: VMWare SVGA device support"
This reverts commit c137d95081.

The VMWare SVGA model now -- since commit 104bd1dc70 in QEMU --
falls back to stdvga (that is, Bochs) if we don't setup VMWare SVGA
FIFO.

To simplify QemuVideoDxe, we don't intend to implement the VMWare SVGA
FIFO setup feature. It means our current VMW SVGA driver code is
basically dead. To simplify the problem, we will replace the old
VMWare SVGA driver to Bochs interface. It should work on all QEMU
version.

The first step for using Bochs interface is to revert old driver.

Laszlo Ersek 91a5b13650 OvmfPkg/PlatformDebugLibIoPort: fix port detection for use in the DXE Core
The DXE Core is one of those modules that call
ProcessLibraryConstructorList() manually.

Before DxeMain() [MdeModulePkg/Core/Dxe/DxeMain/DxeMain.c] calls
ProcessLibraryConstructorList(), and through it, our
PlatformDebugLibIoPortConstructor() function, DxeMain() invokes the
DEBUG() macro multiple times. That macro lands in our
PlatformDebugLibIoPortFound() function -- which currently relies on the
"mDebugIoPortFound" global variable that has (not yet) been set by the
constructor. As a result, early debug messages from the DXE Core are lost.

Move the device detection into PlatformDebugLibIoPortFound(), also caching
the fact (not just the result) of the device detection.

(We could introduce a separate DebugLib instance just for the DXE Core,
but the above approach works for all modules that currently consume the
PlatformDebugLibIoPort instance (which means "everything but SEC").)

This restores messages such as:

> CoreInitializeMemoryServices:
>   BaseAddress - 0x7AF21000 Length - 0x3CDE000 MinimalMemorySizeNeeded - 0x10F4000

Keep the empty constructor function -- OVMF's DebugLib instances have
always had constructors; we had better not upset constructor dependency
ordering by making our instance(s) constructor-less.

It is especially helpful in SEV guest case, in which IO addresses should

Raise the DXEFV size to 11MB.

(For builds that don't need this DXEFV bump, I've checked the
FVMAIN_COMPACT increase stemming from the additional 1MB padding, using
NOOPT + GCC48 + FD_SIZE_2MB, and no other "-D" flags. In the IA32 build,
FVMAIN_COMPACT grows by 232 bytes. In the IA32X64 build, FVMAIN_COMPACT
shrinks by 64 bytes. In the X64 build, FVMAIN_COMPACT shrinks by 376

Laszlo Ersek 02b9a8343f OvmfPkg: introduce PciCapPciIoLib
Add a library class, and a UEFI_DRIVER lib instance, that are layered on
top of PciCapLib, and allow clients to plug an EFI_PCI_IO_PROTOCOL backend
into PciCapLib, for config space access.

(Side note:

Although the UEFI spec says that EFI_PCI_IO_PROTOCOL_CONFIG() returns
EFI_UNSUPPORTED if "[t]he address range specified by Offset, Width, and
Count is not valid for the PCI configuration header of the PCI
controller", this patch doesn't directly document the EFI_UNSUPPORTED
error code, for ProtoDevTransferConfig() and its callers
ProtoDevReadConfig() and ProtoDevWriteConfig(). Instead, the patch refers
to "unspecified error codes". The reason is that in edk2, the
PciIoConfigRead() and PciIoConfigWrite() functions [1] can also return
EFI_INVALID_PARAMETER for the above situation.

Namely, PciIoConfigRead() and PciIoConfigWrite() first call
PciIoVerifyConfigAccess(), which indeed produces the standard
EFI_UNSUPPORTED error code, if the device's config space is exceeded.
However, if PciIoVerifyConfigAccess() passes, and we reach
RootBridgeIoPciRead() and RootBridgeIoPciWrite() [2], then
RootBridgeIoCheckParameter() can still fail, e.g. if the root bridge
doesn't support extended config space (see commit 014b472053).

For all kinds of Limit violations in IO, MMIO, and config space,
RootBridgeIoCheckParameter() returns EFI_INVALID_PARAMETER, not
EFI_UNSUPPORTED. That error code is then propagated up to, and out of,
PciIoConfigRead() and PciIoConfigWrite().

Laszlo Ersek 6a744d40d0 OvmfPkg: introduce PciCapPciSegmentLib
Add a library class, and a BASE lib instance, that are layered on top of
PciCapLib, and allow clients to plug a PciSegmentLib backend into
PciCapLib, for config space access.

(Side note:

The "MaxDomain" parameter is provided because, in practice, platforms
exist where a PCI Express device may show up on a root bridge such that
the root bridge doesn't support access to extended config space. Earlier
the same issue was handled for MdeModulePkg/PciHostBridgeDxe in commit
014b472053. However, that solution does not apply to the PciSegmentLib
class, because:

(1) The config space accessor functions of the PciSegmentLib class, such
    as PciSegmentReadBuffer(), have no way of informing the caller whether
    access to extended config space actually succeeds.

    (For example, in the UefiPciSegmentLibPciRootBridgeIo instace, which
    could in theory benefit from commit 014b472053, the
    EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Pci.Read() status code is explicitly
    ignored, because there's no way for the lib instance to propagate it
    to the PciSegmentLib caller. If the
    EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Pci.Read() call fails, then
    DxePciSegmentLibPciRootBridgeIoReadWorker() returns Data with
    indeterminate value.)

(2) There is no *general* way for any firmware platform to provide, or
    use, a PciSegmentLib instance in which access to extended config space
    always succeeds.

In brief, on a platform where config space may be limited to 256 bytes,
access to extended config space through PciSegmentLib may invoke undefined
behavior; therefore PciCapPciSegmentLib must give platforms a way to
prevent such access.)

Add a library class, and a BASE lib instance, to work more easily with PCI
capabilities in PCI config space. Functions are provided to parse
capabilities lists, and to locate, describe, read and write capabilities.
PCI config space access is abstracted away.

Marc-André Lureau 8d65d3b25e OvmfPkg/PlatformBootManagerLib: process TPM PPI request
Call Tcg2PhysicalPresenceLibProcessRequest() to process pending PPI
requests from PlatformBootManagerAfterConsole().

Laszlo understanding of edk2 is that the PPI operation processing was
meant to occur *entirely* before End-Of-Dxe, so that 3rd party UEFI
drivers couldn't interfere with PPI opcode processing *at all*.

He suggested that we should *not* call
Tcg2PhysicalPresenceLibProcessRequest() from BeforeConsole(). Because,
an "auth" console, i.e. one that does not depend on a 3rd party
driver, is *in general* impossible to guarantee. Instead we could opt
to trust 3rd party drivers, and use the "normal" console(s) in
AfterConsole(), in order to let the user confirm the PPI requests. It
will depend on the user to enable Secure Boot, so that the
trustworthiness of those 3rd party drivers is ensured. If an attacker
roots the guest OS from within, queues some TPM2 PPI requests, and
also modifies drivers on the EFI system partition and/or in GPU option
ROMs (?), then those drivers will not load after guest reboot, and
thus the dependent console(s) won't be used for confirming the PPI
requests.

Marc-André Lureau b9777bb42e OvmfPkg: add Tcg2PhysicalPresenceLibQemu
Cloned "SecurityPkg/Library/DxeTcg2PhysicalPresenceLib" and:

- removed all the functions that are unreachable from
  Tcg2PhysicalPresenceLibProcessRequest() [called from platform BDS],
  or SubmitRequestToPreOSFunction() and
  ReturnOperationResponseToOsFunction() [called from Tcg2Dxe].

- replaced everything that's related to the
  TCG2_PHYSICAL_PRESENCE*_VARIABLE variables, with direct access to
  the QEMU structures.

This commit is based on initial experimental work from Stefan Berger.
In particular, he wrote most of QEMU PPI support, and designed the
qemu/firmware interaction. Initially, Stefan tried to reuse the
existing SecurityPkg code, but we eventually decided to get rid of the
variables and simplify the ovmf/qemu version.

Virtio RNG devices are never boot devices, so in commit 245c643cc8 we
stopped connecting them. This is a problem because an OS boot loader may
depend on EFI_RNG_PROTOCOL to seed the OS's RNG.

Connect Virtio RNG devices again. And, while commit 245c643cc8 removed
that from PlatformBootManagerAfterConsole(), reintroduce it now to
PlatformBootManagerBeforeConsole() -- this way Driver#### options launched

Laszlo Ersek f803c03cc2 OvmfPkg/PlatformBootManagerLib: connect consoles unconditionally
If both ConIn and ConOut exist, but ConIn references none of the PS/2
keyboard, the USB wild-card keyboard, and any serial ports, then
PlatformInitializeConsole() currently allows the boot to proceed without
any input devices at all. This makes for a bad user experience -- the
firmware menu could only be entered through OsIndications, set by a guest
OS.

Do what ArmVirtQemu does already, namely connect the consoles, and add
them to ConIn / ConOut / ErrOut, unconditionally. (The underlying
EfiBootManagerUpdateConsoleVariable() function checks for duplicates.)

The issue used to be masked by the EfiBootManagerConnectAll() call that
got conditionalized in commit 245c643cc8.

This patch is best viewed with "git show -b -W".

BLOCK_MMIO_PROTOCOL and BlockMmioToBlockIoDxe were introduced to OvmfPkg
in March 2010, in adjacent commits b0f5144676 and efd82c5794. In the
past eight years, no driver or application seems to have materialized that
produced BLOCK_MMIO_PROTOCOL instances. Meanwhile the UEFI spec has
developed the EFI_RAM_DISK_PROTOCOL, which edk2 implements (and OVMF
includes) as RamDiskDxe.

Rather than fixing issues in the unused BlockMmioToBlockIoDxe driver,
remove the driver, together with the BLOCK_MMIO_PROTOCOL definition that
now becomes unused too.

Laszlo Ersek 9c7d0d4992 OvmfPkg/TlsAuthConfigLib: configure trusted CA certs for HTTPS boot
Introduce TlsAuthConfigLib to read the list of trusted CA certificates
from fw_cfg and to store it to EFI_TLS_CA_CERTIFICATE_VARIABLE.

The fw_cfg file is formatted by the "p11-kit" and "update-ca-trust"
utilities on the host side, so that the host settings take effect in guest
HTTPS boot as well. QEMU forwards the file intact to the firmware. The
contents are sanity-checked by NetworkPkg/HttpDxe code that was added in
commit 0fd13678a6.

Link TlsAuthConfigLib via NULL resolution into TlsAuthConfigDxe. This sets
EFI_TLS_CA_CERTIFICATE_VARIABLE in time for both
NetworkPkg/TlsAuthConfigDxe (for possible HII interaction with the user)
and for NetworkPkg/HttpDxe (for the effective TLS configuration).

The file formatted by "p11-kit" can be large. On a RHEL-7 host, the the
Mozilla CA root certificate bundle -- installed with the "ca-certificates"
package -- is processed into a 182KB file. Thus, create
EFI_TLS_CA_CERTIFICATE_VARIABLE as a volatile & boot-time only variable.
Also, in TLS_ENABLE builds, set the cumulative limit for volatile
variables (PcdVariableStoreSize) to 512KB, and the individual limit for
the same (PcdMaxVolatileVariableSize) to 256KB.

Laszlo Ersek c5d917158d OvmfPkg/EmuVariableFvbRuntimeDxe: stop using PcdVariableStoreSize
In commit 62f43f7c19, we set PcdVariableStoreSize to the same value as
PcdFlashNvStorageVariableSize (which in turn comes from VARS_LIVE_SIZE in
"OvmfPkg.fdf.inc").

This equality between both PCDs is a false requirement from
EmuVariableFvbRuntimeDxe. FVB drivers should use
PcdFlashNvStorageVariableSize for supporting non-volatile variables (even
if they happen to be kept in RAM only), along the other PcdFlashNvStorage*
PCDs. Whereas PcdVariableStoreSize is for variables that are volatile at
the gRT->SetVariable() / gRT->GetVariable() API level.

(PlatformPei too bases the preallocation for EmuVariableFvbRuntimeDxe on
PcdFlashNvStorageFtwSpareSize.)

Replace PcdVariableStoreSize in EmuVariableFvbRuntimeDxe with the
same-value PcdFlashNvStorageVariableSize. This means no change in
behavior, and it allows us to increase PcdVariableStoreSize in a later
patch without disturbing EmuVariableFvbRuntimeDxe (or PlatformPei).

Functionally this is a no-op:

- The PCI interrupt line register exists only to inform system software
