This commit provides unconditional library resolutions for the OpenSslLib,
IntrinsicLib and BaseCryptLib classes, regardless of whether those classes
are actually used by any module.
Although those libraries depends on OpenSSL, they won't be built unless
a module really uses them. Thus, missing OpenSSL from the tree won't
cause any build failure as long as SECURE_BOOT_ENABLE is false.

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:

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.

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

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.

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.

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.

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.

Also, the RamDiskDxe driver will sometimes report a NVDIMM Root Device

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).

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

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.

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.

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.

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.

Explanation from Michael Kinney:
This PCD allows a platform to provide PlatformSmmBspElection() in a
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.

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.

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

(provided by OvmfPkg/SmmAccess/SmmAccess2Dxe.inf),
- EFI_SMM_CONTROL2_PROTOCOL

(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.

"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.)

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.

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".

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.

OvmfPkg/SmbiosPlatformDxe and OvmfPkg/Library/SmbiosVersionLib. Since both
of those are also used in ArmVirtQemu.dsc, and we should avoid
cross-package commits when possible, this patch declares
PcdQemuSmbiosValidated first, and sets defaults for it in the OvmfPkg DSC
files.

This patch de-duplicates the logic added in commit
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.

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).

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.

While Xen on Intel uses a virtual PCI device to communicate the

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
OVMF.
Here is the table of drivers from Laszlo.
currently included related driver add or replace
from MdeModulePkg in NetworkPkg from NetworkPkg

SnpDxe n/a n/a

Tcp4Dxe TcpDxe replace
Udp4Dxe Udp6Dxe add
UefiPxeBcDxe UefiPxeBcDxe replace
IScsiDxe IScsiDxe 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

This leaves only SEC using the BaseRomAcpiTimerLib instance.

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.
