Some platforms don't support S3 with PcdAcpiS3Enable set as False.
Debug mode bios will ASSERT at this time as Follows.
ASSERT_RETURN_ERROR (Status = Out of Resources)
DXE_ASSERT!: Edk2\MdePkg\Library\BaseS3PciSegmentLib\S3PciSegmentLib.c
(61): !(((INTN)(RETURN_STATUS)(Status)) < 0)
Steps to reproduce the issue:
1.Set PcdAcpiS3Enable to FALSE.
2.Build the bios in debug mode.
3.Power on and Check the serial log.
Note: Prerequisite is that S3PciSegmentLib is Called and
the caller's code is run.
Root Cause:
S3PciSegmentLib call S3BootScriptLib controlled by PcdAcpiS3Enable.
If PcdAcpiS3Enable set as false, S3BootScriptLib will return error
status(Out of Resources).
S3PciSegmentLib will ASSERT if S3BootScriptLib return error.
Solution:
Make S3BootScriptLib return success if PcdAcpiS3Enable was disabled,
which behave as a null S3BootScriptLib instance which just return success
for no action is required to do.

From the perspective of security any external input should be measured
and extended to some registers (TPM PCRs or TDX RTMR registers).
There are below 2 external input in a Td guest:
- TdHob
- Configuration FV (CFV)
TdHob contains the resource information passed from VMM, such as
unaccepted memory region. CFV contains the configurations, such as
secure boot variables.
TdHob and CFV should be measured and extended to RTMRs before they're
consumed. TdHob is consumed in the very early stage of boot process.
At that moment the memory service is not ready. Cfv is consumed in
PlatformPei to initialize the EmuVariableNvStore. To make the
implementation simple and clean, these 2 external input are measured
and extended to RTMRs in SEC phase. That is to say the tdx measurement
is only supported in SEC phase.
After the measurement the hash values are stored in WorkArea. Then after
the Hob service is available, these 2 measurement values are retrieved
and GuidHobs for these 2 tdx measurements are generated.
This patch defines the structure of TDX_MEASUREMENTS_DATA in
SEC_TDX_WORK_AREA to store above 2 tdx measurements. It can be extended
to store more tdx measurements if needed in the future.

QEMU provides the following three files for guest to install the ACPI
tables:
- etc/acpi/rsdp
- etc/acpi/tables
- etc/table-loader
"etc/acpi/rsdp" and "etc/acpi/tables" are similar, they are only kept
separate because they have different allocation requirements in SeaBIOS.
Both of these fw_cfg files contain preformatted ACPI payload.
"etc/acpi/rsdp" contains only the RSDP table, while "etc/acpi/tables"
contains all other tables, concatenated. To be noted, the tables in these
two files have been filled in by qemu, but two kinds of fields are
incomplete: pointers to other tables and checksums (which depend on the
pointers).
"/etc/table-loader" is a linker/loader which provides the commands to
"patch" the tables in "etc/acpi/tables" and then install them. "Patch"
means to fill the pointers and compute the checksum.
From the security perspective these 3 files are the raw data downloaded
from qemu. They should be measured and extended before they're consumed.

ScsiScanCreateDevice(), which will cause a while loop in

In QEMU v5.1.0, the CPU hotplug register block misbehaves: the negotiation
protocol is (effectively) broken such that it suggests that switching from
the legacy interface to the modern interface works, but in reality the
switch never happens. The symptom has been witnessed when using TCG
acceleration; KVM seems to mask the issue. The issue persists with the
following (latest) stable QEMU releases: v5.2.0, v6.2.0, v7.2.0. Currently
there is no stable release that addresses the problem.
The QEMU bug confuses the Present and Possible counting in function
PlatformMaxCpuCountInitialization(), in
"OvmfPkg/Library/PlatformInitLib/Platform.c". OVMF ends up with Present=0
Possible=1. This in turn further confuses MpInitLib in UefiCpuPkg (hence
firmware-time multiprocessing will be broken). Worse, CPU hot(un)plug with
SMI will be summarily broken in OvmfPkg/CpuHotplugSmm, which (considering
the privilege level of SMM) is not that great.
Detect the issue in PlatformCpuCountBugCheck(), and print an error message
and *hang* if the issue is present.
Users willing to take risks can override the hang with the experimental
QEMU command line option
-fw_cfg name=opt/org.tianocore/X-Cpuhp-Bugcheck-Override,string=yes
(The "-fw_cfg" QEMU option itself is not experimental; its above argument,
as far it concerns the firmware, is experimental.)
The problem was originally reported by Ard [0]. We analyzed it at [1] and
[2]. A QEMU patch was sent at [3]; now merged as commit dab30fbef389
("acpi: cpuhp: fix guest-visible maximum access size to the legacy reg

QEMU for x86 has a nasty CPU hotplug bug of which the ramifications are
difficult to oversee, even though KVM acceleration seems to be
unaffected. This has been addressed in QEMU mainline, and will percolate
through the ecosystem at its usual pace. In the mean time, due to the
potential impact on production workloads, we will be updating OVMF to
abort the boot when it detects a QEMU build that is affected.
Tiancore's platform CI uses QEMU in TCG mode, and is therefore impacted
by this mitigation, unless its QEMU builds are updated. This has been
done for Ubuntu-GCC5, but Windows-VS2019 still uses a QEMU build that is
affected.
Aborting the boot upon detecting the QEMU issue will render all boot
tests carried out on Windows-VS2019 broken unless we implement the
'escape hatch' that enables proceed-at-your-own-risk mode, and permits
the boot to proceed even if the QEMU issue is detected.
So let's enable this for Windows-VS2019, and remove it again once it is
no longer needed.

In current DXE FV there are 100+ drivers. Some of the drivers are not
used in Td guest. (Such as USB support drivers, network related drivers,
etc).
From the security perspective if a driver is not used, we'd should prevent
it from being loaded / started. There are 2 benefits:
1. Reduce the attack surface
2. Improve the boot performance
So we separate DXEFV into 2 FVs: DXEFV and NCCFV. All the drivers which
are not needed by a Confidential Computing guest are moved from DXEFV
to NCCFV.
The following patch will find NCCFV for non-cc guest and build FVHob
so that NCCFV drivers can be loaded / started in DXE phase.

The early ID map used by ArmVirtQemu uses ASID scoped non-global
mappings, as this allows us to switch to the permanent ID map seamlessly
without the need for explicit TLB maintenance.
However, this triggers a known erratum on ThunderX, which does not
tolerate non-global mappings that are executable at EL1, as this appears
to result in I-cache corruption. (Linux disables the KPTI based Meltdown
mitigation on ThunderX for the same reason)
So work around this, by detecting the CPU implementor and part number,
and proceeding without the early ID map if a ThunderX CPU is detected.
Note that this requires the C code to be built with strict alignment
again, as we may end up executing it with the MMU and caches off.

I suggest that Gerd be notified about all UefiCpuPkg patches, so he may
take a quick look at, or (by his preference) even test, the proposed
change, in a genuine QEMU/KVM environment.
Assuming this patch is accepted -- subsequently, please *wait* for Gerd's
approval on UefiCpuPkg patches, before merging them.
Notes:
- It's perfectly fine for a reviewer to give an A-b just so the review
process be unblocked, if they don't have anything to add, or don't have
time to review or test in detail. The point is that someone outside of
Intel should *consistently get a chance* to raise concerns about
UefiCpuPkg patches before they are merged.
- My A-b's and R-b's on UefiCpuPkg patches were never supposed to be
"sufficient", only "necessary", for merging. The intent is the same
here, with Gerd's designation as a reviewer.

Similarly to the "cadence" mentioned in commit d272449d9e ("OvmfPkg:

Since the delimiter is not necessary in practice (due to $STEM being

Tested by enabling DEBUG in "VbeShim.asm", running the script, building
OVMF, booting Windows 7, and checking the firmware log (debug console).

UEFI requires us to support nested interrupts, but provides no way for
an interrupt handler to call RestoreTPL() without implicitly
re-enabling interrupts. In a virtual machine, it is possible for a
large burst of interrupts to arrive. We must prevent such a burst
from leading to stack underrun, while continuing to allow nested
interrupts to occur.
This can be achieved by allowing, when provably safe to do so, an
inner interrupt handler to return from the interrupt without restoring
the TPL and with interrupts remaining disabled after IRET, with the
deferred call to RestoreTPL() then being issued from the outer
interrupt handler. This is necessarily messy and involves direct
manipulation of the interrupt stack frame, and so should not be
implemented as open-coded logic within each interrupt handler.
Add the Nested Interrupt TPL Library (NestedInterruptTplLib) to
provide helper functions that can be used by nested interrupt handlers
in place of RaiseTPL()/RestoreTPL().
Example call tree for a timer interrupt occurring at TPL_APPLICATION
with a nested timer interrupt that makes its own call to RestoreTPL():
outer TimerInterruptHandler()
InterruptedTPL == TPL_APPLICATION
...
IsrState->InProgressRestoreTPL = TPL_APPLICATION;
gBS->RestoreTPL (TPL_APPLICATION);
EnableInterrupts();
dispatch a TPL_CALLBACK event
gEfiCurrentTpl = TPL_CALLBACK;
nested timer interrupt occurs
inner TimerInterruptHandler()
InterruptedTPL == TPL_CALLBACK
...
IsrState->InProgressRestoreTPL = TPL_CALLBACK;
gBS->RestoreTPL (TPL_CALLBACK);
EnableInterrupts();
DisableInterrupts();
IsrState->InProgressRestoreTPL = TPL_APPLICATION;
IRET re-enables interrupts
... finish dispatching TPL_CALLBACK events ...
gEfiCurrentTpl = TPL_APPLICATION;
DisableInterrupts();
IsrState->InProgressRestoreTPL = 0;
sees IsrState->DeferredRestoreTPL == FALSE and returns
IRET re-enables interrupts
Example call tree for a timer interrupt occurring at TPL_APPLICATION
with a nested timer interrupt that defers its call to RestoreTPL() to
the outer instance of the interrupt handler:

pages of memory in advance, and all future page tables consumption
will happen in those pool instead of system memory.
Since we have centralized page tables, we only need to mark all page
table pools as RO, instead of searching page table memory layer by
layer in smm page table. Once current page table pool has been used
up, another memory pool will be allocated and the new pool will also
be set as RO if current page table memory has been marked as RO.

TDVF once accepts memory only by BSP. To improve the boot performance
this patch introduce the multi-core accpet memory. Multi-core means
BSP and APs work together to accept memory.
TDVF leverages mailbox to wake up APs. It is not enabled in MpInitLib
(Which requires SIPI). So multi-core accept memory cannot leverages
MpInitLib to coordinate BSP and APs to work together.
So TDVF split the accept memory into 2 phases.
- AcceptMemoryForAPsStack:
BSP accepts a small piece of memory which is then used by APs to setup
stack. We assign a 16KB stack for each AP. So a td-guest with 256 vCPU
requires 255*16KB = 4080KB.
- AcceptMemory:
After above small piece of memory is accepted, BSP commands APs to
accept memory by sending AcceptPages command in td-mailbox. Together
with the command and accpet-function, the APsStack address is send
as well. APs then set the stack and jump to accept-function to accept
memory.
AcceptMemoryForAPsStack accepts as small memory as possible and then jump
to AcceptMemory. It fully takes advantage of BSP/APs to work together.
After accept memory is done, the memory region for APsStack is not used
anymore. It can be used as other private memory. Because accept-memory
is in the very beginning of boot process and it will not impact other
phases.

Since paging is necessary for long mode, the original implementation of

The current modification creates a page table in reserved memory,
avoiding switching modes and reclaiming memory by OS. This modification
is only for 64 bit mode.
More specifically, we keep the AMD logic as the original code flow,

In some cases when the VariableHeader->StartId is VARIABLE_DATA, the
VariableHeader->State is not just one of the four primary states:
VAR_IN_DELETED_TRANSITION, VAR_DELETED, VAR_HEADER_VALID_ONLY, VAR_ADDED.
The state may combined two or three states, e.g.
0x3C = (VAR_IN_DELETED_TRANSITION & VAR_ADDED) & VAR_DELETED
or
0x3D = VAR_ADDED & VAR_DELETED
When the variable store has those variables, system booting/rebooting will

NvVarStore Variable header State was invalid.
ASSERT
/mnt/working/source_code-git/edk2/OvmfPkg/Library/PlatformInitLib/Platform.c(819):

Adding more log to UpdateVariable() and PlatformValidateNvVarStore(), we
saw some variables which have 0x3C or 0x3D state in store.
e.g.
UpdateVariable(), VariableName=BootOrder
L1871, State=0000003F <-- VAR_ADDED
State &= VAR_DELETED=0000003D
FlushHobVariableToFlash(), VariableName=BootOrder

L2376, State=0000003E
State &= VAR_DELETED=0000003C
FlushHobVariableToFlash(), VariableName=InitialAttemptOrder
...
UpdateVariable(), VariableName=ConIn
L1977, State=0000003F
State &= VAR_IN_DELETED_TRANSITION=0000003E
L2376, State=0000003E
State &= VAR_DELETED=0000003C
FlushHobVariableToFlash(), VariableName=ConIn
...
So, only allowing the four primary states is not enough. This patch changes

1. VAR_HEADER_VALID_ONLY (0x7F)
- Header added (*)
2. VAR_ADDED (0x3F)

3. VAR_ADDED & VAR_IN_DELETED_TRANSITION (0x3E)
- marked as deleted, but still valid, before new data is added. (*)
4. VAR_ADDED & VAR_IN_DELETED_TRANSITION & VAR_DELETED (0x3C)
- deleted, after new data is added.
5. VAR_ADDED & VAR_DELETED (0x3D)
- deleted directly, without new data.
(*) means to support surprise shutdown.
And removed (VAR_IN_DELETED_TRANSITION) and (VAR_DELETED) because they are
invalid states.
v2:
Follow Jiewen Yao's suggestion to add the following valid states:

This allows these to be more accurately referenced from other tables.

A typical QEMU fw_cfg read bytes with IOMMU for td guest is that:
(QemuFwCfgReadBytes@QemuFwCfgLib.c is the example)
1) Allocate DMA Access buffer
2) Map actual data buffer
3) start the transfer and wait for the transfer to complete
4) Free DMA Access buffer
5) Un-map actual data buffer
In step 1/2, Private memories are allocated, converted to shared memories.
In Step 4/5 the shared memories are converted to private memories and
accepted again. The final step is to free the pages.
This is time-consuming and impacts td guest's boot perf (both direct boot
and grub boot) badly.
In a typical grub boot, there are about 5000 calls of page allocation and
private/share conversion. Most of page size is less than 32KB.
This patch allocates a memory region and initializes it into pieces of
memory with different sizes. A piece of such memory consists of 2 parts:
the first page is of private memory, and the other pages are shared
memory. This is to meet the layout of common buffer.
When allocating bounce buffer in IoMmuMap(), IoMmuAllocateBounceBuffer()
is called to allocate the buffer. Accordingly when freeing bounce buffer
in IoMmuUnmapWorker(), IoMmuFreeBounceBuffer() is called to free the
bounce buffer. CommonBuffer is allocated by IoMmuAllocateCommonBuffer
and accordingly freed by IoMmuFreeCommonBuffer.
This feature is tested in Intel TDX pre-production platform. It saves up
to hundreds of ms in a grub boot.

Commit 079a58276b ("OvmfPkg/AmdSev/SecretPei: Mark SEV launch secret
area as reserved") marked the launch secret area itself (1 page) as
reserved so the guest OS can use it during the lifetime of the OS.
However, the address and size of the secret area held in the
CONFIDENTIAL_COMPUTING_SECRET_LOCATION struct are declared as STATIC in
OVMF (in AmdSev/SecretDxe); therefore there's no guarantee that it will
not be written over by OS data.
Fix this by allocating the memory for the
CONFIDENTIAL_COMPUTING_SECRET_LOCATION struct with the
EfiACPIReclaimMemory memory type to ensure the guest OS will not reuse
this memory.

When running under SEV-ES, a page of shared memory is allocated for the
GHCB during the SEC phase at address 0x809000. This page of memory is
eventually passed to the OS as EfiConventionalMemory. When running
SEV-SNP, this page is not PVALIDATE'd in the RMP table, meaning that if
the guest OS tries to access the page, it will think that the host has
voilated the security guarantees and will likely crash.
This patch validates this page immediately after EDK2 switches to using
the GHCB page allocated for the PEI phase.
This was tested by writing a UEFI application that reads to and writes
from one byte of each page of memory and checks to see if a #VC
exception is generated indicating that the page was not validated.

The page allocator code in CoreFindFreePagesI() uses a mask derived from
its UINTN Alignment argument to align the descriptor end address of a
MEMORY_MAP entry to the requested alignment, in order to check whether
the descriptor covers enough sufficiently aligned area to satisfy the
request.
However, on 32-bit architectures, 'Alignment' is a 32-bit type, whereas
DescEnd is a 64-bit type, and so the resulting operation performed on
the end address comes down to masking with 0xfffff000 instead of the
intended 0xffffffff_fffff000. Given the -1 at the end of the expression,
the resulting address is 0xffffffff_fffffffff for any descriptor that
ends on a 4G aligned boundary, and this is certainly not what was
intended.
So cast Alignment to UINT64 to ensure that the mask has the right size.

When build in DEBUG, the code asserts that 5LPage support is there
when the physical address width is larger than 48.
In a RELEASE build it will just force LA57 to 1 in CR4
even if CPUID(7).ECX[16] says it is not supported.
UefiCpuPkg: Bug fix in 5LPage handling
The hang (in the ASSERT) in DEBUG is not warranted as there are
legal configurations with CPUID(7).ECX[16](==LA57)=0
and with a physical address width of larger than 48 (like 52).
This is also supported by this code:
https://github.com/tianocore/edk2/blob/master/UefiCpuPkg/PiSmmCpuDxeSmm/X64/PageTbl.c#L221
There (as long as physical address width is smaller or equal to 52)
any address width above 48 will be reduced to 48 and the
system can and will work without 5LPaging.
The forced setting of LA57 in CR4 (in the absence of LA57 in CPUID(7).ECX)
is a spec violation and should not happen.
Hence the proposed fix
a) removes the assert.
b) only returns TRUE from Is5LevelPagingNeeded if 5LPaging is actually
supported by HW.

Due to more core count increasement, it's hard to reflect all APs
state via AP bitvector support in the register. Actually, SMM CPU
driver doesn't need to check each AP state to know all CPUs in SMI
or not, one alternative method is to check the SMM Delayed & Blocked
AP Count number:
APs in SMI + Blocked Count + Disabled Count >= All supported Aps
(code comments explained why can be > All supported Aps)
With above change, the returned value of "SmmRegSmmEnable" &
"SmmRegSmmDelayed" & "SmmRegSmmBlocked" from SmmCpuFeaturesLib
should be the AP count number within the existing CPU package.
For register that return the bitvector state, require
SmmCpuFeaturesGetSmmRegister() returns count number of all bit per
logical processor within the same package.
For register that return the AP count, require
SmmCpuFeaturesGetSmmRegister() returns the register value directly.

But entry point from the DLL is only executed when the module is not

This library supports a Boot Services table library implementation
that allows code dependent upon UefiBootServicesTableLib to operate
in an isolated execution environment such as within
the context of a host-based unit test framework.
The unit test should initialize the Boot Services database with any
required elements (e.g. protocols, events, handles, etc.) prior to
the services being invoked by code under test.
It is strongly recommended to clean any global databases (e.g.
protocol, event, handles, etc.) after every unit test so the tests
execute in a predictable manner from a clean state.
This library is being moved here from PrmPkg so it can be made more
generally available to other packages and improved upon for others
use.

NOR flash emulation under KVM involves switching between two modes,
where array mode is backed by a read-only memslot, and programming mode
is fully emulated, i.e., the memory region is not backed by anything,
and the faulting accesses are forwarded to the VMM by the hypervisor,
which translates them into NOR flash programming commands.
Normally, we are limited to the use of device attributes when mapping
such regions, given that the programming mode has MMIO semantics.
However, when running under KVM, the chosen memory attributes only take
effect when in array mode, since no memory mapping exists otherwise.
This means we can tune the memory mapping so it behaves a bit more like
a ROM, by switching to EFI_MEMORY_WC attributes. This means we no longer
need a special CopyMem() implementation that avoids unaligned accesses
at all cost.

Currently, when dealing with small updates that can be written out
directly (i.e., if they only involve clearing bits and not setting bits,
as the latter requires a block level erase), we iterate over the data
one word at a time, read the old value, compare it, write the new value,
and repeat, unless we encountered a value that we cannot write (0->1
transition), in which case we fall back to a block level operation.
This is inefficient for two reasons:
- reading and writing a word at a time involves switching between array
and programming mode for every word of data, which is
disproportionately costly when running under KVM;
- we end up writing some data twice, as we may not notice that a block
erase is needed until after some data has been written to flash.
So replace this sequence with a single read of up to twice the buffered
write maximum size, followed by one or two buffered writes if the data
can be written directly. Otherwise, fall back to the existing block
level sequence, but without writing out part of the data twice.

DRAM size for ArmVirtQemu).

To substantially reduce the amount of processing that takes place with
the MMU and caches off, implement a version of ArmPlatformLib specific
for QEMU/mach-virt in AArch64 mode that carries a statically allocated
and populated ID map that covers the NOR flash and device region, and
128 MiB of DRAM at the base of memory (0x4000_0000).
Note that 128 MiB has always been the minimum amount of DRAM we support
for this configuration, and the existing code already ASSERT()s in DEBUG
mode when booting with less.

Use the appropriate PCD definition in the ArmVirtQemu DSC so that the

When the memory protections were implemented and enabled on ArmVirtQemu
5+ years ago, we had to work around the fact that GRUB at the time
expected EFI_LOADER_DATA to be executable, as that is the memory type it
allocates when loading its modules.
This has been fixed in GRUB in August 2017, so by now, we should be able
to tighten this, and remove execute permissions from EFI_LOADER_DATA
allocations.

3.Store SystemContext in mActualContextInHandler and set
SystemContext to mExpectedContextAfterException in handler.
4.After return from exception, store Cpu registers in

PF will be assigned Routing ID based on secBusNumber, ReservedBusNum

assigned bus range as SecBusNumber ~ (SubBusNumber=(SecBusNumber +

Thus "+1" in below code will cause extra 1 bus, and introduce a bus hole.
PFRid = EFI_PCI_RID (Bus, Device, Func);

In SR-IOV spec, there is a note in section 2.1.2:

So the issue can be fixed with below code change.

the idea to store the boot order as configured by the VMM in EFI

Traditional q35 memory layout is 2.75 GB of low memory, leaving room

Rebecca reports that builds of AArch64 DSCs that involve PIE linking
when using ELF based toolchains are failing in some cases, resulting in
an error message like
bad definition for symbol '_GLOBAL_OFFSET_TABLE_'@0x72d8 or
unsupported symbol type. For example, absolute and undefined symbols
are not supported.
The reason turns out to be that, while GenFw does carry some logic to
convert GOT based symbol references into direct ones (which is always
possible given that our ELF to PE/COFF conversion only supports fully
linked executables), it does not support all possible combinations of
relocations that the linker may emit to load symbol addresses from the
GOT.
In particular, when performing a non-LTO link on object code built with
GCC using -fpie, we may end up with GOT based references such as the one
below, where the address of the GOT itself is taken, and the offset of
the symbol in the GOT is reflected in the immediate offset of the
subsequent LDR instruction.
838: adrp x0, 16000
838: R_AARCH64_ADR_PREL_PG_HI21 _GLOBAL_OFFSET_TABLE_
83c: ldr x0, [x0, #2536]
83c: R_AARCH64_LD64_GOTPAGE_LO15 _gPcd_BinaryPatch_PcdFdBaseAddress
The reason that we omit GOT based symbol references when performing ELF to
PE/COFF conversion is that the GOT is not described by static ELF
relocations, which means that the ELF file lacks the metadata to
generate the PE/COFF relocations covering the GOT table in the PE/COFF
executable. Given that none of the usual motivations for using a GOT
(copy on write footprint, shared libraries) apply to EFI executables in
the first place, the easiest way around this is to convert all GOT based
symbol address loads to PC relative ADR/ADRP instructions.
So implement this handling for R_AARCH64_LD64_GOTPAGE_LO15 and
R_AARCH64_LD64_GOTOFF_LO15 relocations as well, and turn the LDR
instructions in question into ADR instructions that generate the
address immediately.
This leaves the reference to _GLOBAL_OFFSET_TABLE_ itself, which is what
generated the error to begin with. Considering that this symbol is never
referenced (i.e., it doesn't appear anywhere in the code) and is only
meaningful in combination with R_*_GOT_* based relocations that follow
it, we can just disregard any references to it entirely, given that we
convert all of those followup relocations into direct references.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3974
CcProbeLib once was designed to probe the Confidential Computing guest
type by checking the PcdOvmfWorkArea. But this memory is allocated with
either EfiACPIMemoryNVS or EfiBootServicesData. It cannot be accessed
after ExitBootService. Please see the detailed analysis in BZ#3974.
To fix this issue, CcProbeLib is redesigned as 2 implementation:
- SecPeiCcProbeLib
- DxeCcProbeLib
In SecPeiCcProbeLib we check the CC guest type by reading the
PcdOvmfWorkArea. Because it is used in SEC / PEI and we don't worry about
the issues in BZ#3974.
In DxeCcProbeLib we cache the GuestType in Ovmf work area in a variable.
After that the Guest type is returned with the cached value. So that we
don't need to worry about the access to Ovmf work area after
ExitBootService.
The reason why we probe CC guest type in 2 different ways is the global
varialbe. Global variable cannot be used in SEC/PEI and CcProbe is called
very frequently.

If ReadWrite bit is cleared in PML4[0] and PageTableMap() is called

But since the PML4[0].ReadWrite is 0, [0, 2M] is still read-only.

If the inheritable attributes in ParentPagingEntry conflicts with the

and loosen the attribute in the parent entry.
E.g.: when PDPTE[0].ReadWrite = 0 but caller wants to map [0-2MB as
ReadWrite = 1 (PDE[0].ReadWrite = 1), we need to change

all lower "BitStart" bits of (LinearAddress + Offset) are all-zero.
Because all lower "BitStart" bits of RegionMask is all-one and

Ensure that the PixelInformation field of the
EFI_GRAPHICS_OUTPUT_MODE_INFORMATION structure is zeroed out in
EFI_GRAPHICS_OUTPUT_PROTOCOL.QueryMode() and
EFI_GRAPHICS_OUTPUT_PROTOCOL.SetMode() when PixelFormat is
PixelBlueGreenRedReserved8BitPerColor.
According to UEFI 2.9 Section 12.9, PixelInformation field of the
EFI_GRAPHICS_OUTPUT_MODE_INFORMATION structure is valid only if
PixelFormat is PixelBitMask. This means that firmware is not required
to fill out the PixelInformation field for other PixelFormat types,
which implies that the QemuVideoDxe implementation is technically
correct.
However, not zeroing out those fields will leak the contents of the
memory returned by the memory allocator, so it is better to explicitly
set them to zero.
In addition, the SCT test suite relies on PixelInformation always
having a consistent value, which causes failures.

Writes TianoCore debug logs into the CBMEM console ringbuffer, from
where the user can retrieve them with the `cbmem` userspace utility.
The intention is to aid in debugging non-fatal issues even in release
builds, or simply make TianoCore's logs available to those interested.
Consequently, MDEPKG_NDEBUG must be masked. As an in-memory debug
logging library, ASSERTs must be non-fatal to be seen, so they neither
dead-loop nor create a breakpoint. It is assumed that ASSERT() neither
enforces fatal conditions nor security integrity, as release builds do
not call DebugAssert() from the ASSERT macro.
More detailed debug logs are produced with the DEBUG_CODE macro, but
this guards other debug-related code throughout the codebase. To avoid
changing behaviour on release builds, this is only set for debug builds.
Tested on QEMU, dumping the appropriate memory region in the UEFI shell
shows the TianoCore log. An improved revision of the debug library used
in several coreboot-related EDK2 forks, including MrChromebox's.
Previous revisions also tested on an Acer Aspire VN7-572G laptop.

Currently, "push byte %[Vector]" causes nasm warning when Vector is larger
than 0x7F. This is because push accepts a signed value, and byte means
signed int8. Maximum signed int8 is 0x7F.
When Vector is larger the 0x7F, for example, when Vector is 255, byte 255
turns to -1, and causes the warning "signed byte value exceeds".
To avoid such warning, use dword instead of byte, this will increase 3 bytes
for each IdtVector.
For IA32, the size of IdtVector will increase from 10 bytes to 13 bytes.
For X64, the size of IdtVector will increase from 15 bytes to 18 bytes.

The CM_STD_OBJ_ACPI_TABLE_INFO.AcpiTableRevision can be used to specify
the major revision number of the ACPI table that the generator must use.
Although most ACPI tables only have a major revision number, the FADT
table additionally has a minor revision number.
The FADT generator currently defaults to setting the latest supported
ACPI revision for the FADT table i.e. ACPI 6.4. This means that the minor
revision for the FADT table is always set to 4 and there is no provision
for a user to specify the minor revision to be selected.
Therefore, update CM_STD_OBJ_ACPI_TABLE_INFO to introduce a new field
MinorRevision which can be used to specify the minor revision for an
ACPI table. Also update the FADT generator to validate the supported
FADT revisions ans use the specified minor revision for the FADT table
if supported. If an unsupported minor revision is specified the FADT
generator defaults to the latest supported minor revision.
Since the CM_STD_OBJ_ACPI_TABLE_INFO.MinorRevision field is added to

A memory range can be submitted for attribute changes which is large
enough to not require a page split during the attribute update. Consider
the following scenario:
1. An attribute update removed the RW attribute on a range large enough
to not require a page split.
2. Later, an attributes update is called to re-add the RW attribute for
a subsection of that larger page which requires a split
3. The attribute update logic performs a page split, so now the parent
and child pages have matching attributes
4. Then, the attribute update logic changes the child page to have the
RW attribute.
5. The child page would then correctly have the RW attribute added but
the parent page would still have the RW attribute removed which will
cause an improper access violation.
The page being split should have loose attributes to accommodate the
above case. The split page should always have the attributes set so
the lowest level page frame determines the access rights as detailed
in 4.10.2.2 of the Intel 64 and IA-32 Architectures Software

Consume the host-provided specification of PCI host bridges if

hardware descriptors based on the content of the "hardware-info"
fw-cfg file, if provided. In the affirmative case, use the
resources and attributes specified by the hypervisor for each
Host Bridge to create the RootBridge elements.
In Ovmf platforms, the host can provide the specification of
non-discoverable hardware resources like PCI host bridges. If the
proper fw-cfg file is found, parse the contents provided by the
host into a linked list by using the Hardware Info library. Then,
using the list of PCI host bridges' descriptions, populate the
PCI_ROOT_BRIDGES array with the resources and attributes specified
by the host. If the file is not provided or no Host Bridge is found
in it, fold back to the legacy method based on pre-defined
apertures and rules.
In some use cases, the host requires additional control over the
hardware resources' configurations in the guest for performance and
discoverability reasons. For instance, to disclose information about
the PCI hierarchy to the guest so that this can profit from
optimized accesses. In this case, the host can decide to describe
multiple PCI Host Bridges and provide a specific set of resources
(e.g. MMIO apertures) so that the guest uses the values provided.
Using the provided values may entitle the guest to added performance,
for example by using specific MMIO mappings that can enable peer-to-peer
communication across the PCI hierarchy or by allocating memory closer
to a device for faster DMA transactions.

corresponds to the highest value that must be included in the
guest's physical address space.
Given that platforms with multiple host bridges may provide the PCI
apertures' addresses, the memory detection logic must take into
account that, if the host provided the MMIO windows that can and must
be used, the guest needs to take those values. Therefore, if the
MMIO windows are found in the host-provided fw-cfg file, skip all the
logic calculating the physical address size and just use the value
provided. Since each PCI host bridge corresponds to an element in
the information provided by the host, each of these must be analyzed
looking for the highest address used.

Following the Hardware Info library, create the DxeHardwareInfoLib
which implements the whole API capable of parsing heterogeneous hardware
information. The list-like API grants callers a flexible and common
pattern to retrieve the data. Moreover, the initial source is a BLOB
which generalizes the host-to-guest transmission mechanism.
The Hardware Info library main objective is to provide a way to
describe non-discoverable hardware so that the host can share the
available resources with the guest in Ovmf platforms. This change
features and embraces the main idea behind the library by providing
an API that parses a BLOB into a linked list to retrieve hardware
data from any source. Additionally, list-like APIs are provided so
that the hardware info list can be traversed conveniently.
Similarly, the capability is provided to filter results by specific
hardware types. However, heterogeneous elements can be added to the
list, increasing the flexibility. This way, a single source, for
example a fw-cfg file, can be used to describe several instances of
multiple types of hardware.
This part of the Hardware Info library makes use of dynamic memory
and is intended for stages in which memory services are available.
A motivation example is the PciHostBridgeLib. This library, part
of the PCI driver populates the list of PCI root bridges during DXE
stage for future steps to discover the resources under them. The
hardware info library can be used to obtain the detailed description
of available host bridges, for instance in the form of a fw-cfg file,
and parse that information into a dynmaic list that allows, first to
verify consistency of the data, and second discover the resources
availabe for each root bridge.

Define the HardwareInfoLib API and create the PeiHardwareInfoLib
which implements it, specifically for Pei usage, supporting
only static accesses to parse data directly from a fw-cfg file.
All list-like APIs are implemented as unsupported and only a
fw-cfg wrapper to read hardware info elements is provided.
The Hardware Info library is intended to describe non-discoverable
hardware information and share that from the host to the guest in Ovmf
platforms. The QEMU fw-cfg extension for this library provides a first
variation to parse hardware info by reading it directly from a fw-cfg
file. This library offers a wrapper function to the plain
QmeuFwCfgReadBytes which, specifically, parses header-data pairs out
of the binary values in the file. For this purpose, the approach is
incremental, reading the file block by block and outputting the values
only for a specific known hardware type (e.g. PCI host bridges). One
element is returned in each call until the end of the file is reached.
Considering fw-cfg as the first means to transport hardware info from
the host to the guest, this wrapping library offers the possibility
to statically, and in steps, read a specific type of hardware info
elements out of the file. This method reads one hardware element of a
specific type at a time, without the need to pre-allocate memory and
read the whole file or dynamically allocate memory for each new
element found.
As a usage example, the static approach followed by this library
enables early UEFI stages to use and read hardware information
supplied by the host. For instance, in early times of the PEI stage,
hardware information can be parsed out from a fw-cfg file prescinding
from memory services, that may not yet be available, and avoiding
dynamic memory allocations.

Create the Hardware Info library base together with the specifics to
describe PCI Host Bridges.
The Hardware Info library is intended to be used for disclosing
non-discoverable hardware information from the host to the guest in
Ovmf platforms. Core functionality will provide the possibility to
parse information from a generic BLOB into runtime structures. The
library is conceived in a generic way so that further hardware
elements can also be described using it. For such purpose the length
of the BLOB is not restricted but instead regarded as a sequence of
header-info elements that allow the parsing during runtime. The first
type of hardware defined will be PCI host bridges, providing the
possibility to define multiple and specify the resources each of them
can use. This enables the guest firmware to configure PCI resources
properly. Having the size of each individual element favors the reuse
of a single interface to convey descriptions of an arbitrary number
of heterogenous hardware elements. Furthermore, flexible access
mechanisms coupled with the size will grant the possibility of
interpreting them in a single run.
Define the base types of the generic Hardware Info library to parse
heterogeneous data. Also provide the specific changes to support
PCI host bridges as the first hardware type supported by the
library.
Additionally, define the HOST_BRIDGE_INFO structure to describe PCI
host bridges along with the functionality to parse such information
into proper structures used by the PCI driver in a centralized manner
and taking care of versioning.
As an example and motivation, the library will be used to define
multiple PCI host bridges for complex platforms that require it.
The first means of transportation that will be used is going to be
fw-cfg, over which a stream of bytes will be transferred and later
parsed by the hardware info library. Accordingly, the PCI driver
will make use of these host bridges definitions to populate the
list of Root Bridges and proceed with the configuration and discovery
of underlying hardware components.
As mentioned before, the binary data to be parsed by the Hardware
Info library should be organized as a sequence of Header-element
pairs in which the header describes the type and size of the associated
element that comes right after it. As an illustration, to provide
inforation of 3 host bridges the data, conceptually, would look
like this:
Header PCI Host Bridge (type and size) # 1
PCI Host Bridge info # 1
Header PCI Host Bridge (type and size) # 2
PCI Host Bridge info # 2
Header PCI Host Bridge (type and size) # 3
PCI Host Bridge info # 3

Today InitializeCpuExceptionHandlersEx is called from three modules:
1. DxeCore (links to DxeCpuExceptionHandlerLib)
DxeCore expects it initializes the IDT entries as well as
assigning separate stacks for #DF and #PF.
2. CpuMpPei (links to PeiCpuExceptionHandlerLib)
and CpuDxe (links to DxeCpuExceptionHandlerLib)
It's called for each thread for only assigning separate stacks for
#DF and #PF. The IDT entries initialization is skipped because
caller sets InitData->X64.InitDefaultHandlers to FALSE.
Additionally, SecPeiCpuExceptionHandlerLib, SmmCpuExceptionHandlerLib
also implement such API and the behavior of the API is simply to initialize
IDT entries only.
Because it mixes the IDT entries initialization and separate stacks
assignment for certain exception handlers together, in order to know
whether the function call only initializes IDT entries, or assigns stacks,
we need to check:
1. value of InitData->X64.InitDefaultHandlers
2. library instance
This patch cleans up the code to separate the stack assignment to a new API:
InitializeSeparateExceptionStacks().
Only when caller calls the new API, the separate stacks are assigned.
With this change, the SecPei and Smm instance can return unsupported which
gives caller a very clear status.
The old API InitializeCpuExceptionHandlersEx() is removed in this patch.
Because no platform module is consuming the old API, the impact is none.

Today the DXE instance allocates code page and then copies the IDT
vectors to the allocated code page. Then it fixes up the vector number
in the IDT vector.
But if we update the NASM file to generate 256 IDT vectors, there is
no need to do the copy and fix-up.
A side effect is 4096 bytes (HOOKAFTER_STUB_SIZE * 256) is used for
256 IDT vectors while 32 IDT vectors only require 512 bytes without
this change, in following library instances:
1. 32bit SecPeiCpuExceptionHandlerLib and PeiCpuExceptionHandlerLib
2. 64bit PeiCpuExceptionHandlerLib
