Sean Rhodes ec25e904c7 MdeModulePkg/Bus/Pci/XhciDxe: Check port is compatible before getting PSIV
On some platforms, including Sky Lake and Kaby Lake, the PSIV (Protocol
Speed ID Value) indices are shared between Protocol Speed ID DWORD' in
the extended capabilities registers for both USB2 (Full Speed) and USB3
(Super Speed).

An example can be found below:

    XhcCheckUsbPortSpeedUsedPsic: checking for USB2 ext caps
    XhciPsivGetPsid: found 3 PSID entries
    XhciPsivGetPsid: looking for port speed 1
    XhciPsivGetPsid: PSIV 1 PSIE 2 PLT 0 PSIM 12
    XhciPsivGetPsid: PSIV 2 PSIE 1 PLT 0 PSIM 1500
    XhciPsivGetPsid: PSIV 3 PSIE 2 PLT 0 PSIM 480
    XhcCheckUsbPortSpeedUsedPsic: checking for USB3 ext caps
    XhciPsivGetPsid: found 3 PSID entries
    XhciPsivGetPsid: looking for port speed 1
    XhciPsivGetPsid: PSIV 1 PSIE 3 PLT 0 PSIM 5
    XhciPsivGetPsid: PSIV 2 PSIE 3 PLT 0 PSIM 10
    XhciPsivGetPsid: PSIV 34 PSIE 2 PLT 0 PSIM 1248

The result is edk2 detecting USB2 devices as USB3 devices, which
consequently causes enumeration to fail.

To avoid incorrect detection, check the Compatible Port Offset to find
the starting Port of Root Hubs that support the protocol.

Matt DeVillier 01c2fb0d22 MdeModulePkg/XhciDxe/Xhci: Don't check for invalid PSIV
PSID matching relies on comparing the PSIV against the PortSpeed
value. This patch stops edk2 from checking for a PSIV of 0, as it
is not valid; this reduces the number of register access by
approximately 6 per second.

Xie, Yuanhao 73ccde8f6d UefiCpuPkg: Has APs in 64 bit long-mode before booting to OS.
During the finalization of Mp initialization before booting into the OS,
 depending on whether Mwait is supported or not, AsmRelocateApLoop
 places Aps in MWAIT-loop or HLT-loop.

Since paging is necessary for long mode, the original implementation of
moving APs to 32-bit was to disable paging to ensure that the booting
does not crash.

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,
extract and update the Intel-related code, where the APs would stay
in 64-bit, and run in a Mwait or Hlt loop until the OS wake them up.

Chun-Yi Lee ceb52713b0 OvmfPkg/PlatformInitLib: Fix integrity checking failed of NvVarStore
In the commit 4f173db8b4 "OvmfPkg/PlatformInitLib: Add functions for
EmuVariableNvStore", it introduced a PlatformValidateNvVarStore() function
for checking the integrity of NvVarStore.

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
hangs in a ASSERT:

NvVarStore Variable header State was invalid.
ASSERT
/mnt/working/source_code-git/edk2/OvmfPkg/Library/PlatformInitLib/Platform.c(819):
((BOOLEAN)(0==1))

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
...
UpdateVariable(), VariableName=InitialAttemptOrder
L1977, State=0000003F
State &= VAR_IN_DELETED_TRANSITION=0000003E
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
the falid states list (Follow Jiewen Yao's suggestion):

1. VAR_HEADER_VALID_ONLY (0x7F)
    - Header added (*)
2. VAR_ADDED (0x3F)
    - Header + data added
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:
    VAR_ADDED & VAR_DELETED (0x3D)
    VAR_ADDED & VAR_IN_DELETED_TRANSITION (0x3E)
    VAR_ADDED & VAR_IN_DELETED_TRANSITION & VAR_DELETED (0x3C)
and removed the following invalid states:
    VAR_IN_DELETED_TRANSITION
    VAR_DELETED

Min M Xu c4e76d2fba OvmfPkg/IoMmuDxe: Reserve shared memory region for DMA operation
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4171

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.

Sebastien Boeuf e03b0d0672 OvmfPkg/PlatformInitLib: Differentiate TDX case for Cloud Hypervisor
Rely on the CcProbe() function to identify when running on TDX. This
allows the firmware to follow a different codepath for Cloud Hypervisor,
which means it doesn't rely on PVH to find out about memory below 4GiB.
instead it falls back onto the CMOS to retrieve that information.

Dov Murik 0adc35fccd OvmfPkg/AmdSev/SecretDxe: Allocate secret location as EfiACPIReclaimMemory
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4186

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.

Adam Dunlap 3e3f5bb21c OvmfPkg/PlatformPei: Validate SEC's GHCB page
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.

Fixes: 6995a1b79b ("OvmfPkg: Create a GHCB page for use during Sec phase")

Min M Xu 01c0d3c0d5 OvmfPkg/SecTpmMeasurementLib: Fix the mapping error of PCR and RTMR index
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4179

TDVF has the feature to do RTMR measurement in SEC phase. In the same time
it builds a GUID hob which carries the hash value of the measurement so
that in DXE phase a td event can be created based on this GUID Hob. There
is a mapping error between TPM PCR index and RTMR index according to UEFI
2.10. That PCR6 is missing in the mapping. This patch fixes this issue.

Min M Xu fb91d6cbd0 OvmfPkg/TdTcg2Dxe: Fix the mapping error between PCR index and MR index
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4179

According to UEFI Spec 2.10 it is supposed to return the mapping from PCR
index to CC MR index:
//
// In the current version, we use the below mapping for TDX:
//
// TPM PCR Index | CC Measurement Register Index | TDX-measurement register
// -----------------------------------------------------------------------
// 0             |   0                           |   MRTD
// 1, 7          |   1                           |   RTMR[0]
// 2~6           |   2                           |   RTMR[1]
// 8~15          |   3                           |   RTMR[2]

In the current implementation TdMapPcrToMrIndex returns the index of RTMR,
not the MR index.

After fix the spec unconsistent, other related codes are updated
accordingly.
1) The index of event log uses the input MrIndex.
2) MrIndex is decreated by 1 before it is sent for RTMR extending.
