Ruiyu Ni 984ba6a467 OvmfPkg: Add tftp dynamic command
The TFTP command was converted from a NULL class library instance
to a dynamic shell command in commit 0961002352.
This patch complements commit f9bc2f8763, which only removed the
old library, but didn't add the new dynamic command。

Paolo Bonzini c9eb56e5fd OvmfPkg: create a separate PlatformDebugLibIoPort instance for SEC
The next patch will want to add a global variable to
PlatformDebugLibIoPort, but this is not suitable for the SEC
phase, because SEC runs from read-only flash.  The solution is
to have two library instances, one for SEC and another
for all other firmware phases.  This patch adds the "plumbing"
for the SEC library instance, separating the INF files and
moving the constructor to a separate C source file.

Laszlo Ersek 1958124a6c OvmfPkg: fix dynamic default for oprom verification policy PCD without SB
I missed the following, both while reviewing and while testing commit
6041ac65ae ("OvmfPkg/PlatformPei: DENY_EXECUTE_ON_SECURITY_VIOLATION
when SEV is active", 2017-10-05):

If "-D SECURE_BOOT_ENABLE" is not passed on the "build" command line, then
OVMF has no dynamic default at all for
"PcdOptionRomImageVerificationPolicy". This means that the PcdSet32S()
call added in the subject commit doesn't even compile:

> OvmfPkg/PlatformPei/AmdSev.c: In function 'AmdSevInitialize':
> OvmfPkg/PlatformPei/AmdSev.c:67:3: error: implicit declaration of
> function '_PCD_SET_MODE_32_S_PcdOptionRomImageVerificationPolicy'
> [-Werror=implicit-function-declaration]
>    PcdStatus = PcdSet32S (PcdOptionRomImageVerificationPolicy, 0x4);
>    ^
> cc1: all warnings being treated as errors

Make the current, SB-only, 0x00 dynamic default unconditional.

This is the simplest approach, and it reflects the intent of original
commit 1fea9ddb4e ("OvmfPkg: execute option ROM images regardless of
Secure Boot", 2016-01-07). Without SECURE_BOOT_ENABLE,
"SecurityPkg/Library/DxeImageVerificationLib" is not used anyway, so the
PCD is never read.

This issue was first caught and reported by Gerd Hoffmann
<kraxel@redhat.com>'s Jenkins CI. Later it was also reported in
<https://bugzilla.tianocore.org/show_bug.cgi?id=737>.

Brijesh Singh 6041ac65ae OvmfPkg/PlatformPei: DENY_EXECUTE_ON_SECURITY_VIOLATION when SEV is active
The following commit:

1fea9ddb4e OvmfPkg: execute option ROM images regardless of Secure Boot

sets the OptionRomImageVerificationPolicy to ALWAYS_EXECUTE the expansion
ROMs attached to the emulated PCI devices. A expansion ROM constitute
another channel through which a cloud provider (i.e hypervisor) can
inject a code in guest boot flow to compromise it.

When SEV is enabled, the bios code has been verified by the guest owner
via the SEV guest launch sequence before its executed. When secure boot,
is enabled, lets make sure that we do not allow guest bios to execute a
code which is not signed by the guest owner.

Brijesh Singh f9d129e68a OvmfPkg: Add IoMmuDxe driver
The IOMMU protocol driver provides capabilities to set a DMA access
attribute and methods to allocate, free, map and unmap the DMA memory
for the PCI Bus devices.

Due to security reasons all DMA operations inside the SEV guest must
be performed on shared (i.e unencrypted) pages. The IOMMU protocol
driver for the SEV guest uses a bounce buffer to map guest DMA buffer
to shared pages inorder to provide the support for DMA operations inside
SEV guest.

IoMmuDxe driver looks for SEV capabilities, if present then it installs
the real IOMMU protocol otherwise it installs placeholder protocol.
Currently, PciHostBridgeDxe and QemuFWCfgLib need to know the existance
of IOMMU protocol. The modules needing to know the existance of IOMMU
support should add

  gEdkiiIoMmuProtocolGuid OR gIoMmuAbsentProtocolGuid

in their depex to ensure that platform IOMMU detection has been performed.

Brijesh Singh 24e4ad7554 OvmfPkg: Add AmdSevDxe driver
When SEV is enabled, the MMIO memory range must be mapped as unencrypted
(i.e C-bit cleared).

We need to clear the C-bit for MMIO GCD entries in order to cover the
ranges that were added during the PEI phase (through memory resource
descriptor HOBs). Additionally, the NonExistent ranges are processed
in order to cover, in advance, MMIO ranges added later in the DXE phase
by various device drivers, via the appropriate DXE memory space services.

The approach is not transparent for later addition of system memory ranges
to the GCD memory space map. (Such ranges should be encrypted.) OVMF does
not do such a thing at the moment, so this approach should be OK.

The driver is being added to the APRIORI DXE file so that, we clear the
C-bit from MMIO regions before any driver accesses it.

Brijesh Singh 13b5d743c8 OvmfPkg/PlatformPei: Set memory encryption PCD when SEV is enabled
Secure Encrypted Virtualization (SEV) guest VMs have the concept of
private and shared memory. Private memory is encrypted with the
guest-specific key, while shared memory may be encrypted with hypervisor
key.  Certain types of memory (namely instruction pages and guest page
tables) are always treated as private memory by the hardware.
For data memory, SEV guest VMs can choose which pages they would like
to be private. The choice is done using the standard CPU page tables
using the C-bit. When building the initial page table we mark all the
memory as private.

The patch sets the memory encryption PCD. The PCD is consumed by the
following edk2 modules, which manipulate page tables:

- PEI phase modules: CapsulePei, DxeIplPeim, S3Resume2Pei.

CapsulePei is not used by OVMF. DxeIplPeim consumes the PCD at the
end of the PEI phase, when it builds the initial page tables for the
DXE core / DXE phase. S3Resume2Pei does not consume the PCD in its
entry point function, only when DxeIplPeim branches to the S3 resume
path at the end of the PEI phase, and calls S3Resume2Pei's
EFI_PEI_S3_RESUME2_PPI.S3RestoreConfig2() member function.

Therefore it is safe to set the PCD for these modules in PlatformPei.

- DXE phase modules: BootScriptExecutorDxe, CpuDxe, PiSmmCpuDxeSmm.

They are all dispatched after the PEI phase, so setting the PCD for
them in PlatformPei is safe. (BootScriptExecutorDxe is launched "for
real" in the PEI phase during S3 resume, but it caches the PCD into a
static variable when its entry point is originally invoked in DXE.)

However, EmuVariableFvbRuntimeDxe is excluded from the SMM_REQUIRE build,
and then noone consumes PcdEmuVariableNvStoreReserved. Don't waste
reserved memory whenever that's the case.

(Even a dynamic default for PcdEmuVariableNvStoreReserved would be
unnecessary; but that way the PcdSet64S() call in the

Laszlo Ersek 62f43f7c19 OvmfPkg: sync PcdVariableStoreSize with PcdFlashNvStorageVariableSize
"MdeModulePkg/MdeModulePkg.dec" declares PcdVariableStoreSize like this:

> The size of volatile buffer. This buffer is used to store VOLATILE
> attribute variables.

There is no inherent reason why the size of the volatile variable store
should match the same of the non-volatile variable store. Indeed flash
variables in the 4MB build work fine without this equality.

However, OvmfPkg/EmuVariableFvbRuntimeDxe uses PcdVariableStoreSize to
initialize the non-volatile VARIABLE_STORE_HEADER too. (Presumably based
on the fact that ultimately that storage will not be permanent.) When
using EmuVariableFvbRuntimeDxe in the 4MB build, the mismatch between the
two mentioned PCDs (which is apparent through EmuVariableFvbRuntimeDxe's
VARIABLE_STORE_HEADER) triggers an assertion in the variable driver:

> ASSERT MdeModulePkg/Universal/Variable/RuntimeDxe/Variable.c(3772):
> mNvVariableCache->Size == VariableStoreLength

Bringing PcdVariableStoreSize in sync with PcdFlashNvStorageVariableSize
fixes this. It also happens to ensure a volatile store size in the 4MB
build that equals the non-volatile store size, which likely doesn't hurt
for symmetry.

Laszlo Ersek b24fca0575 OvmfPkg: introduce 4MB flash image (mainly) for Windows HCK
The "Confirm64KilobytesOfUnauthenticatedVariableStorage" test case of the
Secure Boot Logo Test ("Microsoft.UefiSecureBootLogo.Tests") suite in the
Microsoft Hardware Certification Kit expects to be able to populate the
variable store up to roughly 64 KB, with a series of 1 KB sized,
unauthenticated variables. OVMF's current live varstore area is too small
for this: 56 KB.

Introduce the FD_SIZE_4MB build macro (equivalently, FD_SIZE_IN_KB=4096),
which

- enlarges the full flash image to 4MB -- QEMU supports up to 8MB, see
  FLASH_MAP_BASE_MIN in "hw/i386/pc_sysfw.c" --,

- inside that, grows the varstore area / pflash chip to 528 KB, and within
  it, the live area from 56 KB to 256 KB.

Importantly, a firmware binary built with -D FD_SIZE_4MB will *not* be
compatible with a variable store that originates from a variable store
template built *without* -D FD_SIZE_4MB. This is the reason for the large
increase, as every such change breaks compatibility between a new firmware
binary and old varstore files.

Enlarging the varstore does not impact the performance of normal
operations, as we keep the varstore block size 4KB. The performance of
reclaim is affected, but that is expected (since reclaim has to rework the
full live area). And, reclaim occurs proportionally less frequently.

While at it, the FVMAIN_COMPACT volume (with the compressed FFS file in
it) is also enlarged significantly, so that we have plenty of room for
future DXEFV (and perhaps PEIFV) increments -- DXEFV has been growing
steadily, and that increase shows through compression too. Right now the
PEIFV and DXEFV volumes need no resizing.

Here's a summary:

  Description                Compression type                Size [KB]

Laszlo Ersek 210270730c OvmfPkg: introduce the FD_SIZE_IN_KB macro / build flag
FD_SIZE_xMB defines have existed for flash size selection. They can be
passed as "-D FD_SIZE_xMB" on the command line. Passing multiple of them
at the same time has never been supported; earlier settings on the command
line cannot be overridden.

Introduce the integer valued FD_SIZE_IN_KB macro, which provides the
following improvements:

- several instances of it are permitted on the command line, with the last
  one taking effect,

- conditional statements in the DSC and FDF files need only check a single
  macro, and multiple values can be checked in a single !if with the ||
  operator,

- nested !ifdef / !else ladders can be replaced with flat equality tests,

- in the future, flash sizes can be expressed with a finer than MB
  granularity, if necessary.

For now, we're going to preserve the FD_SIZE_xMB defines as convenience
wrappers for FD_SIZE_IN_KB.

FD_SIZE_IN_KB is being added to the DSC files because this way we can
depend on it in both the DSC and FDF files.

Bhupesh Sharma 6e5e544f22 OvmfPkg: Install BGRT ACPI table
While debugging OS for ACPI BGRT support (especially on VMs),
it is very useful to have the EFI firmware (OVMF in most cases
which use Tianocore) to export the ACPI BGRT table.

This patch tries to add this support in OvmfPkg.

Tested this patch in the following environments:

1. On both RHEL7.3 and Fedora-25 VM guests running on a Fedora-24 Host:
   - Ensured that the BGRT logo is properly prepared and
     can be viewed with user-space tools (like 'Gwenview' on KDE,
     for example):

     $ file /sys/firmware/acpi/bgrt/image
     /sys/firmware/acpi/bgrt/image: PC bitmap, Windows 3.x format, 193 x
     58 x 24

2. On a Windows-10 VM Guest running on a Fedora-24 Host:
   - Ensured that the BGRT ACPI table is properly prepared and can be
     read with freeware tool like FirmwareTablesView:

     ==================================================
     Signature         : BGRT
     Firmware Provider : ACPI
     Length            : 56
     Revision          : 1
     Checksum          : 129

     Creator Revision  : 0x01000013
     Description       :
     ==================================================

Note from Laszlo Ersek <lersek@redhat.com>: without the BGRT ACPI table,
Windows 8 and Windows 10 first clear the screen, then display a blue,
slanted Windows picture above the rotating white boot animation. With the
BGRT ACPI table, Windows 8 and Windows 10 don't clear the screen, the blue
Windows image is not displayed, and the rotating white boot animation is
shown between the firmware's original TianoCore boot splash and (optional)
"Start boot option" progress bar.

QemuFwCfgRead16() will return 0, and then we stick with the current

Cinnamon Shia a6d594c5fa OvmfPkg: use StatusCode Router and Handler from MdeModulePkg
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.

Laszlo Ersek f0e6a56a9a OvmfPkg: include UefiCpuPkg/CpuMpPei
In the next patch we're going to put EFI_PEI_MP_SERVICES_PPI to use.

CpuMpPei uses the following PCDs from gUefiCpuPkgTokenSpaceGuid, beyond
those already used by CpuDxe:

- PcdCpuMicrocodePatchAddress and PcdCpuMicrocodePatchRegionSize: these
  control whether CpuMpPei performs microcode update. If the region size
  is zero, then the microcode update is skipped. UefiCpuPkg.dec sets the
  region size to zero by default, which is appropriate for OVMF.

- PcdCpuApLoopMode and PcdCpuApTargetCstate: the former controls how
  CpuMpPei puts the APs to sleep: 1 -- HLT, 2 -- MWAIT, 3 -- busy wait
  (with PAUSE). The latter PCD is only relevant if the former PCD is 2
  (MWAIT). In order to be consistent with SeaBIOS and with CpuDxe itself,
  we choose HLT. That's the default set by UefiCpuPkg.dec.

Furthermore, although CpuMpPei could consume SecPeiCpuExceptionHandlerLib
technically, it is supposed to consume PeiCpuExceptionHandlerLib. See:

- http://thread.gmane.org/gmane.comp.bios.edk2.devel/12703

- git commit a81abf1616 ("UefiCpuPkg/ExceptionLib: Import
  PeiCpuExceptionHandlerLib module"), part of the series linked above.

Jeff recommended to resolve CpuExceptionHandlerLib to
PeiCpuExceptionHandlerLib for all PEIMs:

- http://thread.gmane.org/gmane.comp.bios.edk2.devel/14471/focus=14477

Since at the moment we have no resolution in place that would cover this
for PEIMs (from either [LibraryClasses] or [LibraryClasses.common.PEIM]),
it's easy to do.

Laszlo Ersek 8aba40b792 OvmfPkg: add PciHotPlugInitDxe
After IncompatiblePciDeviceSupportDxe, this is another small driver /
protocol implementation that tweaks the behavior of the PCI bus driver in
edk2.

The protocol is specified in the Platform Init Spec v1.4a, Volume 5,
Chapter 12.6 "PCI Hot Plug PCI Initialization Protocol". This
implementation steers the PCI bus driver to reserve the following
resources ("padding") for each PCI bus, in addition to the BARs of the
devices on that PCI bus:
- 2MB of 64-bit non-prefetchable MMIO aperture,
- 512B of IO port space.

The goal is to reserve room for devices hot-plugged at runtime even if the
bridge receiving the device is empty at boot time.

The 2MB MMIO size is inspired by SeaBIOS. The 512B IO port size is
actually only 1/8th of the PCI spec mandated reservation, but the
specified size of 4096 has proved wasteful (given the limited size of our
IO port space -- see commit bba734ab4c). Especially on Q35, where every
PCIe root port and downstream port qualifies as a separate bridge (capable
of accepting a single device).

Test results for this patch:
- regardless of our request for 64-bit MMIO reservation, it is downgraded
  to 32-bit,
- although we request 512B alignment for the IO port space reservation,
  the next upstream bridge rounds it up to 4096B.

Laszlo Ersek a3cd5cd5f6 OvmfPkg/PlatformBootManagerLib: rebase boot logo display to BootLogoLib
In the course of porting OvmfPkg to the MdeModulePkg BDS, commit
817fb3ac2a

  OvmfPkg/PlatformBootManagerLib: Add EnableQuietBoot & DisableQuietBoot

open-coded the EnableQuietBoot() function (and its dependencies / friends)
from IntelFrameworkModulePkg BDS.

This code duplication can be avoided; the functionality is available from
the following three libraries in MdeModulePkg:

- BootLogoLib: provides the BootLogoEnableLogo() function. It does not
  provide the internal ConvertBmpToGopBlt() function -- that one is
  delegated to ImageDecoderLib (function DecodeImage()).

- ImageDecoderLib: a general library that registers decoder plugins for
  specific image formats, and provides the generic DecodeImage() on top.

- BmpImageDecoderLib: one of said decoder plugins, for handling BMP images
  (which is the format of our logo).

In this patch, we revert 817fb3ac2a, and atomically incorporate the
above libraries. This is inspired by Nt32Pkg commit 859e75c4fc42:

  Nt32Pkg: Use BootLogoLib for logo and progress bar drawing.

Laszlo Ersek 855743f717 OvmfPkg: prevent 64-bit MMIO BAR degradation if there is no CSM
According to edk2 commit

  "MdeModulePkg/PciBus: do not improperly degrade resource"

and to the EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL definition in the
Platform Init 1.4a specification, a platform can provide such a protocol
in order to influence the PCI resource allocation performed by the PCI Bus
driver.

In particular it is possible instruct the PCI Bus driver, with a
"wildcard" hint, to allocate the 64-bit MMIO BARs of a device in 64-bit
address space, regardless of whether the device features an option ROM.

(By default, the PCI Bus driver considers an option ROM reason enough for
allocating the 64-bit MMIO BARs in 32-bit address space. It cannot know if
BDS will launch a legacy boot option, and under legacy boot, a legacy BIOS
binary from a combined option ROM could be dispatched, and fail to access
MMIO BARs in 64-bit address space.)

In platform code we can ascertain whether a CSM is present or not. If not,
then legacy BIOS binaries in option ROMs can't be dispatched, hence the
BAR degradation is detrimental, and we should prevent it. This is expected
to conserve the 32-bit address space for 32-bit MMIO BARs.

The driver added in this patch could be simplified based on the following
facts:

- In the Ia32 build, the 64-bit MMIO aperture is always zero-size, hence
  the driver will exit immediately. Therefore the driver could be omitted
  from the Ia32 build.

- In the Ia32X64 and X64 builds, the driver could be omitted if CSM_ENABLE
  was defined (because in that case the degradation would be justified).
  On the other hand, if CSM_ENABLE was undefined, then the driver could be
  included, and it could provide the hint unconditionally (without looking
  for the Legacy BIOS protocol).

These short-cuts are not taken because they would increase the differences
between the OVMF DSC/FDF files. If we can manage without extreme
complexity, we should use dynamic logic (vs. build time configuration),
plus keep conditional compilation to a minimum.

Laszlo Ersek dd43486577 OvmfPkg: remove USE_OLD_BDS build fallback macro
Reasons:

- USE_OLD_BDS requires duplicating updates between OVMF's library
  instances that depend on USE_OLD_BDS being FALSE vs. TRUE. Examples:

  d5aee61bfa OvmfPkg/QemuNewBootOrderLib: adapt Q35 SATA PMPN to UEFI

  1da7616649 OvmfPkg/QemuBootOrderLib: adapt Q35 SATA PMPN to UEFI spec
               Mantis 1353

- The Xen community has embraced the new BDS. Examples:

  14b2ebc30c OvmfPkg/PlatformBootManagerLib: Postpone the shell
               registration

  49effaf26e OvmfPkg/PciHostBridgeLib: Scan for root bridges when
               running over Xen

- OVMF doesn't build with "-D USE_OLD_BDS -D HTTP_BOOT_ENABLE" anyway, as
  NetworkPkg/HttpBootDxe now requires UefiBootManagerLib:

  50a65824c7 NetworkPkg: Use UefiBootManagerLib API to create load
               option.

  We (correctly) don't resolve UefiBootManagerLib when USE_OLD_BDS is
  TRUE.

- The new BDS has been working well; for example it's the only BDS
  available in ArmVirtPkg:

Hao Wu 259d87146b OvmfPkg: Modify FDF/DSC files for RamDiskDxe's adding NFIT report feature
The RamDiskDxe driver in MdeModulePkg now will use EFI_ACPI_TABLE_PROTOCOL
and EFI_ACPI_SDT_PROTOCOL during reporting RAM disks to NVDIMM Firmware
Interface Table (NFIT).

A Pcd 'PcdInstallAcpiSdtProtocol' controls whether the
EFI_ACPI_SDT_PROTOCOL will be produced. Its default value is set to FALSE
in MdeModulePkg. To make the NFIT reporting feature working properly under
OVMF, the patch will set the Pcd to TRUE in OVMF DSC files.

Also, the RamDiskDxe driver will sometimes report a NVDIMM Root Device
using ASL code which is put in a Secondary System Description Table (SSDT)
according to the ACPI 6.1 spec.

Locating the SSDT requires modifying the [Rule.Common.DXE_DRIVER] field in
OVMF FDF files.

Edk2 commit 8a45f80eda ("MdeModulePkg: Make HII configuration settings
available to OS runtime") implements the optional UEFI feature described
in "31.2.11.1 OS Runtime Utilization" in UEFI v2.6.

While this feature might show benefits down the road even in QEMU virtual
machines, at the moment it only presents drawbacks:
- it increases the EfiRuntimeServicesData footprint,
- it triggers HII compatibility problems between edk2 and external drivers
  unconditionally, even if the end-user is not interested in HII and/or in
  configuring said drivers (see
  <https://www.redhat.com/archives/vfio-users/2016-March/msg00153.html>
  and <http://thread.gmane.org/gmane.comp.bios.edk2.devel/9894> for an
  example).

While the feature was being introduced, popular demand for a controlling
Feature PCD rose (see
<http://thread.gmane.org/gmane.comp.bios.edk2.devel/7626>), which is why
we can set it now to FALSE.

Laszlo Ersek 7e5b1b670c OvmfPkg: PlatformPei: determine the 64-bit PCI host aperture for X64 DXE
The main observation about the 64-bit PCI host aperture is that it is the
highest part of the useful address space. It impacts the top of the GCD
memory space map, and, consequently, our maximum address width calculation
for the CPU HOB too.

Thus, modify the GetFirstNonAddress() function to consider the following
areas above the high RAM, while calculating the first non-address (i.e.,
the highest inclusive address, plus one):

- the memory hotplug area (optional, the size comes from QEMU),

- the 64-bit PCI host aperture (we set a default size).

While computing the first non-address, capture the base and the size of
the 64-bit PCI host aperture at once in PCDs, since they are natural parts
of the calculation.

(Similarly to how PcdPciMmio32* are not rewritten on the S3 resume path
(see the InitializePlatform() -> MemMapInitialization() condition), nor
are PcdPciMmio64*. Only the core PciHostBridgeDxe driver consumes them,
through our PciHostBridgeLib instance.)

Set 32GB as the default size for the aperture. Issue#59 mentions the
NVIDIA Tesla K80 as an assignable device. According to nvidia.com, these
cards may have 24GB of memory (probably 16GB + 8GB BARs).

As a strictly experimental feature, the user can specify the size of the
aperture (in MB) as well, with the QEMU option

  -fw_cfg name=opt/ovmf/X-PciMmio64Mb,string=65536

The "X-" prefix follows the QEMU tradition (spelled "x-" there), meaning
that the property is experimental, unstable, and might go away any time.
Gerd has proposed heuristics for sizing the aperture automatically (based
on 1GB page support and PCPU address width), but such should be delayed to
a later patch (which may very well back out "X-PciMmio64Mb" then).

For "everyday" guests, the 32GB default for the aperture size shouldn't
impact the PEI memory demand (the size of the page tables that the DXE IPL
PEIM builds). Namely, we've never reported narrower than 36-bit addresses;
the DXE IPL PEIM has always built page tables for 64GB at least.

For the aperture to bump the address width above 36 bits, either the guest
must have quite a bit of memory itself (in which case the additional PEI
memory demand shouldn't matter), or the user must specify a large aperture
manually with "X-PciMmio64Mb" (and then he or she is also responsible for
giving enough RAM to the VM, to satisfy the PEI memory demand).

Laszlo Ersek 7b8fe63561 OvmfPkg: PlatformPei: enable PCIEXBAR (aka MMCONFIG / ECAM) on Q35
The comments in the code should speak for themselves; here we note only
two facts:

- The PCI config space writes (to the PCIEXBAR register) are performed
  using the 0xCF8 / 0xCFC IO ports, by virtue of PciLib being resolved to
  BasePciLibCf8. (This library resolution will permanently remain in place
  for the PEI phase.)

- Since PCIEXBAR counts as a chipset register, it is the responsibility of
  the firmware to reprogram it at S3 resume. Therefore
  PciExBarInitialization() is called regardless of the boot path. (Marcel
  recently posted patches for SeaBIOS that implement this.)

This patch suffices to enable PCIEXBAR (and the dependent ACPI table
generation in QEMU), for the sake of "PCIeHotplug" in the Linux guest:

  ACPI: MCFG 0x000000007E17F000 00003C
        (v01 BOCHS  BXPCMCFG 00000001 BXPC 00000001)
  PCI: MMCONFIG for domain 0000 [bus 00-ff] at [mem 0x80000000-0x8fffffff]
       (base 0x80000000)

  acpi PNP0A08:00: _OSC: OS now controls

In the following patches, we'll equip the core PCI host bridge / root
bridge driver and the rest of DXE as well to utilize ECAM on Q35.

The old driver is retained for now; it remains available with "-D

Laszlo Ersek 75f4533119 OvmfPkg: resolve PciSegmentLib
In the next patch we'll build "MdeModulePkg/Bus/Pci/PciHostBridgeDxe".
That driver depends on the PciSegmentLib class. Edk2 offers four
instances:

(1) MdePkg/Library/UefiPciSegmentLibPciRootBridgeIo/

    Inappropriate here because it consumes
    EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL, but
    "MdeModulePkg/Bus/Pci/PciHostBridgeDxe" needs the library class for
    producing that protocol.

(2) MdePkg/Library/PeiPciSegmentLibPciCfg2/

    Restricted to PEIM, SEC, and PEI_CORE client modules.

(3) MdePkg/Library/DxePciSegmentLibEsal/

    "uses ESAL services to perform PCI Configuration cycles"

(4) MdePkg/Library/BasePciSegmentLibPci/

    A simple BASE library instance that sits on top of PciLib. This is our
    choice. We can resolve PciSegmentLib to this instance for all module
    types.

Laszlo Ersek 1fea9ddb4e OvmfPkg: execute option ROM images regardless of Secure Boot
Change the image verification policy for option ROM images to 0x00
(ALWAYS_EXECUTE).

While this may not be a good idea for physical platforms (see e.g.
<https://trmm.net/Thunderstrike>), on the QEMU platform the benefits seem
to outweigh the drawbacks:

- For QEMU's virtual PCI devices, and for some assigned PCI devices, the
  option ROMs come from host-side files, which can never be rewritten from
  within the guest. Since the host admin has full control over a guest
  anyway, executing option ROMs that originate from host-side files
  presents no additional threat to the guest.

- For assigned physical PCI devices with option ROMs, the argument is not
  so clear-cut. In theory a setup could exist where:

  - the host-side UEFI firmware (with DENY_EXECUTE_ON_SECURITY_VIOLATION)
    rejects the option ROM of a malicious physical PCI device, but

  - when the device is assigned to the guest, OVMF executes the option ROM
    in the guest,

  - the option ROM breaks out of the guest (using an assumed QEMU
    vulnerability) and gains QEMU user privileges on the host.

  However, in order to escalate as far as it would happen on the bare
  metal with ALWAYS_EXECUTE (i.e., in order to gain firmware-level access
  on the host), the malicious option ROM would have to break through (1)
  QEMU, (2) traditional UID and GID based privilege separation on the
  host, (3) sVirt (SELinux) on the host, (4) the host OS - host firmware
  boundary. This is not impossible, but not likely enough to discourage
  the use cases below.

- This patch makes it possible to use unsigned iPXE network drivers that
  QEMU presents in the option ROMs of virtual NICs and assigned SR-IOV
  VFs, even if Secure Boot is in User Mode or Deployed Mode.

- The change also makes it possible to execute unsigned, outdated
  (revoked), or downright malicious option ROMs of assigned physical
  devices in guests, for corporate, entertainment, academia, or security
  research purposes.

Laszlo Ersek 65d2bf4223 OvmfPkg: inherit Image Verification Policy defaults from SecurityPkg
Secure Boot support was originally addded to OvmfPkg on 2012-Mar-09, in
SVN r13093 (git 8cee3de7e9), titled

  OvmfPkg: Enable secure-boot support when SECURE_BOOT_ENABLE==TRUE

At that time the image verification policies in
SecurityPkg/SecurityPkg.dec were:

- option ROM image:      0x00 (ALWAYS_EXECUTE)
- removable media image: 0x05 (QUERY_USER_ON_SECURITY_VIOLATION)
- fixed media image:     0x05 (QUERY_USER_ON_SECURITY_VIOLATION)

The author of SVN r13093 apparently didn't want to depend on the
SecurityPkg defaults for the latter two image origins, plus the
ALWAYS_EXECUTE policy for option ROM images must have been deemed too lax.
For this reason SVN r13093 immediately spelled out 0x05
(QUERY_USER_ON_SECURITY_VIOLATION) within OvmfPkg for all three image
origins.

Fast forward to 2013-Aug-28: policy 0x05
(QUERY_USER_ON_SECURITY_VIOLATION) had been forbidden in the UEFI spec,
and SVN r14607 (git db44ea6c4e) reflected this in the source code:

- The policies for the latter two image origins were switched from 0x05 to
  0x04 (DENY_EXECUTE_ON_SECURITY_VIOLATION) in SecurityPkg,

- the patch changed the default policy for option ROM images too, from
  0x00 (ALWAYS_EXECUTE) to 0x04 (DENY_EXECUTE_ON_SECURITY_VIOLATION),

- any other client DSC files, including OvmfPkg's, underwent a whole-sale
  0x05 (QUERY_USER_ON_SECURITY_VIOLATION) -> 0x04
  (DENY_EXECUTE_ON_SECURITY_VIOLATION) replacement too.

The practical result of that patch for OvmfPkg was that the explicit 0x04
settings would equal the strict SecurityPkg defaults exactly.

And that's what we have today: the "override the default values from
SecurityPkg" comments in OvmfPkg's DSC files are stale, in practice.

It is extremely unlikely that SecurityPkg would change the defaults from
0x04 (DENY_EXECUTE_ON_SECURITY_VIOLATION) any time in the future, so let's
just inherit those in OvmfPkg.

Laszlo Ersek bb0f18b0bc OvmfPkg: any AP in SMM should not wait for the BSP for more than 100 ms
This patch complements the previous one, "OvmfPkg: use relaxed AP SMM
synchronization mode". While that patch focuses on the case when the SMI
is raised synchronously by the BSP, on the BSP:

  BSPHandler()             [UefiCpuPkg/PiSmmCpuDxeSmm/MpService.c]
    SmmWaitForApArrival()  [UefiCpuPkg/PiSmmCpuDxeSmm/MpService.c]
      IsSyncTimerTimeout() [UefiCpuPkg/PiSmmCpuDxeSmm/SyncTimer.c]

this patch concerns itself with the case when it is one of the APs that
raises (and sees delivered) the synchronous SMI:

  APHandler()            [UefiCpuPkg/PiSmmCpuDxeSmm/MpService.c]
    IsSyncTimerTimeout() [UefiCpuPkg/PiSmmCpuDxeSmm/SyncTimer.c]

Namely, in APHandler() the AP waits for the BSP to enter SMM regardless of
PcdCpuSmmSyncMode, for PcdCpuSmmApSyncTimeout microseconds (the default
value is 1 second). If the BSP doesn't show up in SMM within that
interval, then the AP brings it in with a directed SMI, and waits for the
BSP again for PcdCpuSmmApSyncTimeout microseconds.

Although during boot services, SmmControl2DxeTrigger() is only called by
the BSP, at runtime the OS can invoke runtime services from an AP (it can
even be forced with "taskset -c 1 efibootmgr"). Because on QEMU
SmmControl2DxeTrigger() only raises the SMI for the calling processor (BSP
and AP alike), the first interval above times out invariably in such cases
-- the BSP never shows up before the AP calls it in.

In order to mitigate the performance penalty, decrease
PcdCpuSmmApSyncTimeout to one tenth of its default value: 100 ms. (For
comparison, Vlv2TbltDevicePkg sets 1 ms.)

NOTE: once QEMU becomes capable of synchronous broadcast SMIs, this patch
and the previous one ("OvmfPkg: use relaxed AP SMM synchronization mode")
should be reverted, and SmmControl2DxeTrigger() should be adjusted
instead.

Paolo Bonzini 9b1e378811 OvmfPkg: use relaxed AP SMM synchronization mode
Port 0xb2 on QEMU only sends an SMI to the currently executing processor.
The SMI handler, however, and in particular SmmWaitForApArrival, currently
expects that SmmControl2DxeTrigger triggers an SMI IPI on all processors
rather than just the BSP.  Thus all SMM invocations loop for a second (the
default value of PcdCpuSmmApSyncTimeout) before SmmWaitForApArrival sends
another SMI IPI to the APs.

With the default SmmCpuFeaturesLib, 32-bit machines must broadcast SMIs
because 32-bit machines must reset the MTRRs on each entry to system
management modes (they have no SMRRs).  However, our virtual platform
does not have problems with cacheability of SMRAM, so we can use "directed"
SMIs instead.  To do this, just set gUefiCpuPkgTokenSpaceGuid.PcdCpuSmmSyncMode
to 1 (aka SmmCpuSyncModeRelaxedAp).  This fixes SMM on multiprocessor virtual
machines.

  platform specific SmmCpuPlatformHookLib instance to decide which CPU
  gets elected to be the BSP in each SMI.

  The SmmCpuPlatformHookLibNull [instance] always returns EFI_NOT_READY
  for that function, which makes the module behave the same as the PCD
  being set to FALSE.

  The default is TRUE, so the platform lib is always called, so a platform
  developer can implement the hook function and does not have to also
  change a PCD setting for the hook function to be active.

  A platform that wants to eliminate the call to the hook function
  [altogether] can set the PCD to FALSE.

  So for OVMF, I think it makes sense to set this PCD to FALSE in the DSC
  file.

Laszlo Ersek decb365b00 OvmfPkg: select LocalApicLib instance with x2apic support
Although neither LocalApicLib instance is suitable for runtime DXE drivers
(because they access the APIC at the physical address retrieved from
either MSR_IA32_APIC_BASE_ADDRESS or PcdCpuLocalApicBaseAddress), they are
suitable for SMM drivers -- SMM drivers are not influenced by the runtime
OS's virtual address map.

PiSmmCpuDxeSmm links against LocalApicLib. 64-bit Linux guests tend to
enable x2apic mode even in simple VCPU configurations (e.g., 4 sockets, 1
core/socket, 1 thread/core):

  [    0.028173] x2apic enabled

If PiSmmCpuDxeSmm was linked with the BaseXApicLib instance (i.e., with no
x2apic support), then the next runtime service call that is backed by an
SMM driver triggers the following ASSERT in BaseXApicLib (because the
latter notices that x2apic has been enabled, which it doesn't support):

  ASSERT .../UefiCpuPkg/Library/BaseXApicLib/BaseXApicLib.c(263):
  ApicBaseMsr.Bits.Extd == 0

It is reasonable to give all LocalApicLib client modules in OVMF the same
level of x2apic support, hence resolve LocalApicLib globally to
BaseXApicX2ApicLib. This will not be conditional on -D SMM_REQUIRE,
because BaseXApicX2ApicLib is compatible with BaseXApicLib in any
environment where the latter can be used.

Laszlo Ersek 67d8659474 OvmfPkg: LockBox: use SMM stack with -D SMM_REQUIRE
During DXE, drivers save data in the LockBox. A save operation is layered
as follows:

- The unprivileged driver wishing to store data in the LockBox links
  against the "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxDxeLib.inf"
  library instance.

  The library allows the unprivileged driver to format requests for the
  privileged SMM LockBox driver (see below), and to parse responses.

  We apply this resolution for DXE_DRIVER modules.

- The privileged SMM LockBox driver is built from
  "MdeModulePkg/Universal/LockBox/SmmLockBox/SmmLockBox.inf". This driver
  has module type DXE_SMM_DRIVER and can access SMRAM.

  The driver delegates command parsing and response formatting to
  "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxSmmLib.inf".

  Therefore we include this DXE_SMM_DRIVER in the build, and apply said
  resolution specifically to it.

  (Including the driver requires us to resolve a few of other library
  classes for DXE_SMM_DRIVER modules.)

- In PEI, the S3 Resume PEIM (UefiCpuPkg/Universal/Acpi/S3Resume2Pei)
  retrieves data from the LockBox. It is capable of searching SMRAM
  itself.

  We resolve LockBoxLib to
  "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxPeiLib.inf" specifically
  for this one PEIM.

"MdeModulePkg/Core/PiSmmCore/PiSmmIpl.inf" (a DXE_RUNTIME_DRIVER)
implements the SMM Initial Program Loader. It produces
EFI_SMM_BASE2_PROTOCOL and EFI_SMM_COMMUNICATION_PROTOCOL, relying on:
- EFI_SMM_ACCESS2_PROTOCOL
  (provided by OvmfPkg/SmmAccess/SmmAccess2Dxe.inf),
- EFI_SMM_CONTROL2_PROTOCOL
  (provided by OvmfPkg/SmmControl2Dxe/SmmControl2Dxe.inf).

(The SMM IPL also depends on EFI_SMM_CONFIGURATION_PROTOCOL_GUID, but this
dependency is not enforced in the entry point. A protocol notify callback
is registered instead, hence we can delay providing that protocol via the
PiSmmCpuDxeSmm driver that is (to be) imported from UefiCpuPkg/.)

The SMM IPL loads the SMM core into SMRAM and executes it from there.
Therefore we add the SMM core to the build as well.

For the SMM core, a number of library classes need to be resolved.
Furthermore, each FDF file must provide the GenFds.py BaseTools utility
with a build rule for SMM_CORE; we copy the DXE_CORE's rule.

Laszlo Ersek 9d560947f6 OvmfPkg: add PEIM for providing TSEG-as-SMRAM during PEI
"MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxPeiLib.inf" is the
LockBoxLib instance with SMRAM access for the PEI phase.

Said library instance must, and can, access the LockBox data in SMRAM
directly if it is invoked before SMBASE relocation / SMI handler
installation. In that case, it only needs PEI_SMM_ACCESS_PPI from the
platform, and it doesn't depend on EFI_PEI_SMM_COMMUNICATION_PPI.

OVMF satisfies the description in SVN r18823 ("MdeModulePkg:
SmmLockBoxPeiLib: work without EFI_PEI_SMM_COMMUNICATION_PPI"): in OVMF,
only S3Resume2Pei links against SmmLockBoxPeiLib.

Therefore, introduce a PEIM that produces the PEI_SMM_ACCESS_PPI
interface, enabling SmmLockBoxPeiLib to work; we can omit including
"UefiCpuPkg/PiSmmCommunication/PiSmmCommunicationPei.inf".

The load / installation order of S3Resume2Pei and SmmAccessPei is
indifferent. SmmAccessPei produces the gEfiAcpiVariableGuid HOB during its
installation (which happens during PEI), but S3Resume2Pei accesses the HOB
only when the DXE IPL calls its S3RestoreConfig2 PPI member, as last act
of PEI.

MCH_SMRAM_D_LCK and MCH_ESMRAMC_T_EN are masked out the way they are, in
SmmAccessPeiEntryPoint() and SmramAccessOpen() respectively, in order to
prevent VS20xx from warning about the (otherwise fully intentional)
truncation in the UINT8 casts. (Warnings reported by Michael Kinney.)

Laszlo Ersek c075d250f6 OvmfPkg: make PcdPropertiesTableEnable dynamic
Since PcdPropertiesTableEnable is used by the DXE Core (in the
InstallPropertiesTable() function, which runs at End-of-Dxe), we must also
change the PcdLib class resolution for that module, from the default
BasePcdLibNull to DxePcdLib.

Traditionally we've considered the DXE Core to be incapable of accessing
dynamic PCDs -- the PCD PPI is not available any longer to the DXE Core,
and the PCD Protocol is not available to it *yet*. There are exceptions
however: if the DXE Core can ensure, by whatever means, that the PCD
Protocol *is* available, then DxePcdLib will just work (the latter even
lists DXE_CORE as an allowed client module type). Namely, DxePcdLib looks
up the PCD Protocol dynamically, on the first library call that actually
needs it (for accessing a dynamic PCD); the lookup doesn't occur in a
library constructor.

And because the DXE Core fetches PcdPropertiesTableEnable at End-of-Dxe,
the PCD Protocol is definitely available then.

In addition, we change the default value of PcdPropertiesTableEnable from
the inherited TRUE to FALSE. It makes no difference at this point (our
runtime DXE drivers are not built with the required 4KB section alignment
anyway), but it's better to be clear about this. The properties table
feature requires OS compatibility, and it breaks Windows 7 minimally.
Therefore the default should be FALSE.

Laszlo Ersek ead7cb12d5 OvmfPkg: prevent code execution from DXE stack
SVN rev 18166 ("MdeModulePkg DxeIpl: Add stack NX support") enables
platforms to request non-executable stack for the DXE phase, by setting
PcdSetNxForStack to TRUE.

The PCD defaults to FALSE, because:

(a) A non-executable DXE stack is a new feature and causes changes in
    behavior. Some platform could rely on executing code from the stack.

(b) The code enabling NX in the DXE IPL PEIM enforces the

      PcdSetNxForStack ==> PcdDxeIplBuildPageTables

    implication for "64-bit PEI + 64-bit DXE" platforms, with a new
    ASSERT(). Some platform might not comply with this requirement
    immediately.

Regarding (a), in none of the OVMF builds do we try to execute code from
the stack.

Regarding (b):

- In the OvmfPkgX64.dsc build (which is where (b) applies) we simply
  inherit the PcdDxeIplBuildPageTables|TRUE default from
  "MdeModulePkg/MdeModulePkg.dec". Therefore we can set PcdSetNxForStack
  to TRUE.

- In OvmfPkgIa32X64.dsc, page tables are built by default for DXE. Hence
  we can set PcdSetNxForStack to TRUE.

- In OvmfPkgIa32.dsc, page tables used not to be necessary until now.
  After we set PcdSetNxForStack to TRUE in this patch, the DXE IPL will
  construct page tables even when it is built as part of OvmfPkgIa32.dsc,
  provided the (virtual) hardware supports both PAE mode and the XD bit.

Should this setting cause problems in a GPU (or other device) passthru
scenario, with a UEFI_DRIVER in the PCI option rom attempting to execute
code from the stack, the feature can be dynamically disabled on the QEMU
command line, with "-cpu <MODEL>,-nx".

Gary Ching-Pang Lin ab44a6e833 OvmfPkg: Add HttpBoot support
This commit introdues a new build option to OvmfPkg: HTTP_BOOT_ENABLE.
When HttpBoot is enabled, a new Network boot option will show in the
boot manager menu with the device path like this:

PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv4(0.0.0.0)/Uri()

It works like the PXE one but fetches the NBP from the given http
url instead of the tftp service.

A simple testing environment can be set up with the QEMU tap network
and dnsmasq + lighttpd.

Here is the example of the dnsmasq config:

  interface=<tap interface>
  dhcp-range=192.168.111.100,192.168.111.120,12h
  dhcp-option=60,"HTTPClient"
  dhcp-boot="http://<tap ip>/<efi file>"

It's similar to the PXE server settings except the tftp function is
disabled, the option 60 must be "HTTPClient", and the boot uri is a
http url.

Laszlo Ersek 98937dc293 OvmfPkg: set SMBIOS version in DetectSmbiosVersionLib instead of PlatformPei

  OvmfPkg: PlatformPei: set SMBIOS entry point version dynamically

(git 37baf06b, SVN r17676) by hooking DetectSmbiosVersionLib into
SmbiosDxe.

Although said commit was supposed to work with SMBIOS 3.0 payloads from
QEMU, in practice that never worked, because the size / signature checks
in SmbiosVersionInitialization() would always fail, due to the SMBIOS 3.0
entry point being structurally different. Therefore this patch doesn't
regress OvmfPkg.

Laszlo Ersek 37baf06b44 OvmfPkg: PlatformPei: set SMBIOS entry point version dynamically
Git commit 54753b60 (SVN r16870), "MdeModulePkg: Update SMBIOS revision to
3.0." changed PcdSmbiosVersion from 0x0208 to 0x0300. This controls the
version number of the SMBIOS entry point table (and other things) that
"MdeModulePkg/Universal/SmbiosDxe" installs.

Alas, this change breaks older Linux guests, like RHEL-6 (up to RHEL-6.7);
those are limited to 2.x (both in the guest kernel firmware driver, and in
the dmidecode utility). The SMBIOS 3.0 entry point has a different GUID --
defined in UEFI 2.5 -- pointing to it in the UEFI Configuration Table, and
guest kernels that lack upstream kernel commit e1ccbbc9d5 don't recognize
it.

The v2.1.0+ machine types of QEMU generate SMBIOS payload for the firmware
to install. The payload includes the entry point table ("anchor" table).
OvmfPkg/SmbiosPlatformDxe cannot install the anchor table (because that is
the jurisdiction of the generic "MdeModulePkg/Universal/SmbiosDxe"
driver); however, we can parse the entry point version from QEMU's anchor
table, and instruct "MdeModulePkg/Universal/SmbiosDxe" to adhere to that
version.

On machine types older than v2.1.0, the feature is not available, but
then, should anything in OVMF install SMBIOS tables, version 2.8 is simply
safer / more widely supported than 3.0 -- hence the default 2.8 value for
the dynamic PCD.

We set the PCD in PlatformPei (when not on the S3 resume path), because
that's an easy and certain way to set the PCD before a DXE driver reads
it. This follows the example of PcdEmuVariableNvStoreReserved (which is
read by EmuVariableFvbRuntimeDxe).

Laszlo Ersek 47e57f4f5f OvmfPkg: include XHCI driver
QEMU commit aa685789 ("xhci: generate a Transfer Event for each Transfer
TRB with the IOC bit set") fixed an emulation problem in QEMU; we can now
drive that host controller with edk2's XhciDxe. Include it in OvmfPkg, as
XHCI emulation is reportedly more virtualization-friendly than EHCI,
consuming less CPU.

The driver can be tested with the following QEMU command line options:

  -device nec-usb-xhci -device usb-kbd

This patch should not regress existing QEMU command lines (ie. trigger an
ASSERT() in XhciDxe that fails on pre-aa685789 QEMU) because QEMU's
"-device nec-usb-xhci" has never before resulted in USB devices that
worked with edk2 firmware builds, hence users have never had a reason to
add that option.

Now that they learn about XHCI support in OVMF by reading this commit
message, they (or their packagers) will also know to update qemu to
aa685789 or later (in practice that means the upcoming 2.3 release), at
least if they want to use '-device nec-usb-xhci' with edk2, for the first
time ever.

There are several network stack drivers in MdeModulePkg or NetworkPkg.
Currently, we only use the drivers from MdeModulePkg which only provides
the IPv4 support. This commit adds the IPv6 drivers in NetworkPkg into

Here is the table of drivers from Laszlo.

UefiPxeBcDxe        UefiPxeBcDxe    replace

Since the TcpDxe, UefiPxeBcDxe, and IScsiDxe drivers in NetworkPkg also
support IPv4, we replace the ones in MdeModulePkg.

To enable the IPv6 support, build OVMF with "-D NETWORK_IP6_ENABLE".
A special case is NetworkPkg/IScsiDxe. It requires openssl. For convenience,
NetworkPkg/IScsiDxe is enabled only if both IPv6 and SecureBoot are enabled.

Since in OVMF both PEI_CORE and PEIM run from RAM, and thus may
utilize global variables, use the "Base" AcpiTimerLib instance
(instead of BaseRom) to take advantage of the improved efficiency
of storing the timer register IO address in a global variable.

This leaves only SEC using the BaseRomAcpiTimerLib instance.

Gabriel Somlo 170ef2d916 OvmfPkg: AcpiTimerLib: Split into multiple phase-specific instances
Remove local power management register access macros in favor of
factored-out ones in OvmfPkg/Include/OvmfPlatforms.h

Next, AcpiTimerLib is split out into three instances, for use during
various stages:

  - BaseRom: used during SEC, PEI_CORE, and PEIM;
  - Dxe:     used during DXE_DRIVER and DXE_RUNTIME_DRIVER;
  - Base:    used by default during all other stages.

Most of the code remains in AcpiTimerLib.c, to be shared by all
instances. The two platform-dependent methods (constructor and
InternalAcpiGetTimerTick) are provided separately by source files
specific to each instance, namely [BaseRom|Base|Dxe]AcpiTimerLib.c.

Since pre-DXE stages can't rely on storing data in global variables,
methods specific to the "BaseRom" instance will call platform
detection macros each time they're invoked.

The "Base" instance calls platform detection macros only from its
constructor, and caches the address required by InternalAcpiTimerTick
in a global variable.

The "Dxe" instance is very similar to "Base", except no platform
detection macros are called at all; instead, the platform type is
read via a dynamic PCD set from PlatformPei.

Laszlo Ersek b1220e2820 OvmfPkg: BDS: drop custom boot timeout, revert to IntelFrameworkModulePkg's
PlatformBdsEnterFrontPage() already implements a keypress wait (for
entering the setup utility at boot) with a nice progress bar, only OVMF
has not been using it.

Removing our custom code and utilizing PlatformBdsEnterFrontPage()'s
builtin wait has the following benefits:

- It simplifies OVMF's BDS code.

- Because now we call PlatformBdsEnterFrontPage() unconditionally, it
  actually has a chance to look at the EFI_OS_INDICATIONS_BOOT_TO_FW_UI
  bit of the "OsIndications" variable, improving compliance with the UEFI
  specification. References:
  - https://bugzilla.redhat.com/show_bug.cgi?id=1153927
  - http://thread.gmane.org/gmane.comp.bios.tianocore.devel/10487

- The progress bar looks nice. (And it keeps the earlier behavior intact,
  when the user presses a key on the TianoCore splash screen.)

  In any case, we set the timeout to 0 (which doesn't show the progress
  bar and proceeds to the boot options immediately) in order to keep the
  boot time down.

The commit message is not overly verbose:

  OvmfPkg: Add custom SecureBootConfigDxe that doesn't reset

  We don't force a platform reset for OVMF when PK is changed in custom
  mode setup.

But the INF file hunk is telling:

  Need custom SecureBootConfigDxe for OVMF that does not force resets
  after PK changes since OVMF doesn't have persistent variables

We do have persistent variables now. Let's disable the (now obsolete)
OvmfPkg fork, and revert to the (well maintained) SecurityPkg-provided
config driver.

This driver (from

is first loaded normally during DXE. When the
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed by any DXE driver (purely

During S3 Resume / PEI, the driver image is executed from there. In order
to access the boot script saved during S3 Suspend, LockBox access is
needed.

The boot script is transferred internal to PiDxeS3BootScriptLib:

Both S3SaveStateDxe and BootScriptExecutorDxe are statically linked
against PiDxeS3BootScriptLib. Whichever is loaded first (during normal
boot, in the DXE phase), allocates the root storage for the script. The
address is then passed between the PiDxeS3BootScriptLib instances living
in the two separate drivers thru the dynamic
PcdS3BootScriptTablePrivateDataPtr PCD.

"MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf" produces
the EFI_S3_SAVE_STATE_PROTOCOL which allows creation and saving of an S3
Boot Script, to be replayed in PEI during S3 Resume. The script contains
opcodes and opcode arguments to configure CPU, PCI and IO resources.

S3SaveStateDxe relies on the S3BootScriptLib library. The Null
implementation is not useful for actually saving the boot script, we need
the PiDxeS3BootScriptLib instance.

The PiDxeS3BootScriptLib library instance depends on LockBoxLib,
implemented for OVMF in one of the previous patches.

PiDxeS3BootScriptLib also depends on SmbusLib. For now we opt for the Null
instance of the latter. It means that SMBus commands in the boot script
will have no effect when interpreted during S3 Resume. This should be fine
for OvmfPkg and QEMU.

Laszlo Ersek 5fb6fc0f05 OvmfPkg: S3 Resume: pull in PEIM orchestrating S3 Resume
"UefiCpuPkg/Universal/Acpi/S3Resume2Pei/S3Resume2Pei.inf" produces the
EFI_PEI_S3_RESUME2 PEIM-to-PEIM Interface.

When the platform-specific initialization code (in PEI) sets the Boot Mode
to BOOT_ON_S3_RESUME, the DXE IPL (which is the last step in PEI) skips
the DXE phase entirely, and executes the S3 Resume PEIM through the
EFI_PEI_S3_RESUME2 interface instead. (See DxeLoadCore() in
"MdeModulePkg/Core/DxeIplPeim/DxeLoad.c".)

S3Resume2Pei depends on LockBoxLib.

Laszlo Ersek 2d441ca9cd OvmfPkg: unify PcdMaxVariableSize at 0x2000 bytes
The Linux persistent store (pstore) feature serves, among other things,
for saving the trailing portion of the dmesg in case of a kernel oops. One
backend for the pstore facility is "efivars", ie. non-volatile UEFI
variables.

Linux splits the tail of the dmesg that is to be dumped in 1KB chunks, and
tries to save each chunk as a specially (and differently) named
non-volatile variable. The 1KB chunk size accounts for the variable data
only; Linux expects this size to be available per variable *without*
accounting for the variable name or any firmware-internal overhead.

For non-authenticated (ie. non-secure-boot) variables, OvmfPkg currently
sets the per-variable limit to 0x400 (1KB) through PcdMaxVariableSize.
However this PCD determines the size *before* subtracting the internal
overhead (which is sizeof(VARIABLE_HEADER) == 0x20 bytes for
non-authenticated variables, see
"MdeModulePkg/Include/Guid/VariableFormat.h"), and also before subtracting
the given variable's UCS-2 encoded name (including the trailing 0x0000).

Linux maximizes these special variable names in DUMP_NAME_LEN==52 code
points (including the trailing NUL). Hence we must provide at least

  0x020 == sizeof(VARIABLE_HEADER), for the internal overhead
  0x068 == 2 * 52, for the UCS-2 encoded name, including trailing 0x0000
  0x400 for the variable body
  -----
  0x488 == 1160

bytes in PcdMaxVariableSize, so that Linux's efivars-backed pstore can
work even on non-secure-boot builds of OVMF.

However, as PcdMaxVariableSize=0x2000 has proven reasonable when secure
boot is enabled, it should also be okay when secure boot is disabled; so
for simplicity's sake set PcdMaxVariableSize to 0x2000 unconditionally.

This is to prepare for QEMU flash support which will allow

Note two size changes:
 * NV Varstore size increased from 0xc000 to 0xe000
 * FTW work size decreased from 0x2000 to 0x1000

The reason for this change is that the fault-tolerant write
support requires that the work area fit within the block
just before the fault-tolerant write spare storage blocks.
Since QEMU flash blocks have a size of 0x1000, this means
that the maximum FTW work size is 0x1000.

v2:

The only choice for (a) used to be the proprietary Intel E1000 driver,
which is cumbersome to obtain and enable.

The iPXE UEFI NIC drivers packaged with qemu-1.5 cover (a) for each NIC
type supported by qemu, and are easy to obtain & configure, even for
earlier qemu versions. Therefore enable (b) per default as well.

This doesn't take up much space; the binaries (b) adds to the firmware
don't seem to need -D FD_SIZE_2MB.

jljusten 0b5a5022e5 OvmfPkg: Disable debugging for UNIXGCC to save space
UNIXGCC builds larger images than GCC44, and can have issues
fitting into the FD image. Therefore, when using UNIXGCC,
debug will be disabled by default.

The README file is updated with instructions for selectively
enabling debug for UNIXGCC.

jljusten b90aefa9e4 OvmfPkg: add support for debug console on port 0x402
This patch adds support for a debug console on the same port that is used
by SeaBIOS.  This makes it easier to debug OVMF, because it does not mix
debug and serial output on the same device.  It also makes it easier to
leave some of the debug messages on even in release builds.

To enable it, pass "-debugcon stdio -global isa-debugcon.iobase=0x402" to
QEMU.

The new mechanism is enabled by default, but a regular serial console can
be chosen by adding -D DEBUG_ON_SERIAL_PORT to the build options.

In order to support the degree of flexibility, the DebugLib needs to use library to abstract the get/set operations to the filter mask.
