RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Intel's Trust Domain Extensions (Intel TDX) refers to an Intel technology
that extends Virtual Machines Extensions (VMX) and Multi-Key Total Memory
Encryption (MKTME) with a new kind of virutal machines guest called a
Trust Domain (TD). A TD is desinged to run in a CPU mode that protects the
confidentiality of TD memory contents and the TD's CPU state from other
software, including the hosting Virtual-Machine Monitor (VMM), unless
explicitly shared by the TD itself.
There are 2 configurations for TDVF to upstream. See below link for
the definitions of the 2 configurations.
https://edk2.groups.io/g/devel/message/76367
This patch-set is to enable the basic feature of Config-B in OvmfPkg.
- Add a standalone IntelTdxX64.dsc to a TDX specific directory for a
*full* feature TDVF. (Align with existing SEV)
- IntelTdxX64.dsc includes TDX/normal OVMF basic boot capability. The
final binary can run on TDX/normal OVMF.
- PEI phase is skipped.
By design in Config-B there should be more advanced features, such as:
- RTMR based measurement and measure boot.
- Remove unnecessary drivers to reduce attack surface, such as
network stack.
To make the code review more efficiency, Config-B is split into 2 waves:
- Basic feature of Config-B
- Advanced feature of Config-B
This patch-set is for *Basic feature of Config-B*.
Code at: https://github.com/mxu9/edk2/tree/tdvf_wave3.v3
Please be noted:
This patch-set is based on tdvf_wave2.v6 which is at:
https://github.com/mxu9/edk2/tree/tdvf_wave2.v6
v3 changes:
- Drop the PcdTdxWorkAreaBase introduced in v2. Instead PcdSevEsWorkArea
is used to point to the TDX WorkArea. PcdSevEsWorkArea will be renamed
to PcdCcWorkAreaBase in the future.
- In v2 TdHob is processed in OvmfPkg/IntelTdx/Sec/IntelTdx.c. Since
the codes have been moved to PlatformInitLib, IntelTdx.c is deleted.
- Add comments in DxeAcpiTimerLib to explain why both
PcdOvmfHostBridgePciDevId and EFI_HOB_PLATFORM_INFO are checked to
read HostBridgeDevId.
v2 changes:
- In v1 PEI phase is skipped during boot process. But the code is still
in the image. It is not a good way. So in v2 the code of PEI is
removed as well.
- In v1 PrePiLib in EmbeddedPkg are updated to meet the requirement of
TDVF-Config-B. This is because PrePiLib in EmbeddedPkg is designed for
the situation of PEI-less boot. So after PEI is removed, this change
is not needed anymore.
- In v1 only Tdx guest can be brought up. Now v2 brings up both Legacy
guest and Tdx guest.
- Platform initialization in TdxStartup is refactored with the
PlatformInitLib.
- OvmfPkg/IntelTdx/Sec is introduced. It is a simplied version of
OvmfPkg/Sec.

This library sets / gets the Hob list pointer in TDX_WORK_AREA.
This is because it is designed to be used in SEC where the value of
global variable cannot be saved, so the Hob list pointer is saved
in TDX_WORK_AREA.
TDX_WORK_AREA shares the same base address as SEV_WORK_AREA which is
pointed by PcdSevEsWorkAreaBase. This PCD will be renamed to
PcdCcWorkAreaBase as Gerd suggested.

This patch-sets is to bring up Legacy guest and Tdx guest without
PEI phase. So platform initialization has to be done in SEC phase.
It is similar to the work of OvmfPkg/PlatformPei. In
OvmfPkg/PlatformPei some PCDs are set during platform initialization,
such as PcdPciMmio64Base. But in PEI-less boot, PCDs cannot be set.
So these values are saved in EFI_HOB_PLATFORM_INFO. Then in the early
stage of DXE phase this hob will be parsed and PCDs are set accordingly.

TdxStarupLib provides a function (TdxStartup ()) which brings up both
Legacy and Tdx guest from SEC phase to DXE phase. PEI phase is skipped
so that the attack surfaces are reduced as much as possible.
TdxStartup() does below tasks:
1. Contruct the FW hoblist.
Since PEI is skipped, we must find a memory region which is the
largest one below 4GB. Then this memory region will be used as the
firmware hoblist.
2. Initialize the platform.
3. Build various Hobs, such as SecFv Hob, DxeFv Hob, Stack Hob, etc.
4. At last DXE Core is located / loaded and transfer control to it.

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
OvmfPkg/IntelTdx/Sec is a simplied version of OvmfPkg/Sec. There
are below differences between these 2 Sec
- IntelTdx/Sec only supports Legacy guest and Tdx guest in X64.
- IntelTdx/Sec calls TdxStartup () to jump from SEC to DXE directly.
- IntelTdx/Sec uses MemoryAllocationLib / HobLib / PrePiLib in
EmbeddedPkg.

TDX_PEI_LESS_BOOT indicates the boot without PEI phase. In this case
settings in EFI_HOB_PLATFORM_INFO should be set to its according PCDs.
TdxDxe driver is workable for both Legacy guest and Tdx guest. It is
because for Legacy guest (in PEI-less boot) there should be a place
to set the PCDs based on EFI_HOB_PLATFORM_INFO hob. TdxDxe driver is
the right place to do this work.

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
The entrypoint of DxeAcpiTimerLib checks HostBridgeDevId by reading
PcdOvmfHostBridgePciDevId. If the DevId is not set, ASSERT is
triggered. Normally this DevId is set in PlatformPei which is executed
in PEI phase.
This patch-set is introducing PEI-less boot which means PEI phase is
skipped. So there is no chance to set this DevId. Instead HostBridgeDevId
is set in PlatformInfoHob. So we can check if PlatformInfoHob exists and
if HostBridgeDevId is set in this Hob.
Here is the summary:
- For boot without Pei phase, HostBridgeDevId is set in PlatformInfoHob.
- For boot with Pei phase, HostBridgeDevId is set in
PcdOvmfHostBridgePciDevId.
As the first stage DxeAcpiTimerLib first checks PlatformInfoHob then
the PcdOvmfHostBridgePciDevId. We will revisit here after HostBridgeDevId
is uniformly set in PlatformInfoHob.

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Intel's Trust Domain Extensions (Intel TDX) refers to an Intel technology
that extends Virtual Machines Extensions (VMX) and Multi-Key Total Memory
Encryption (MKTME) with a new kind of virutal machines guest called a
Trust Domain (TD). A TD is desinged to run in a CPU mode that protects the
confidentiality of TD memory contents and the TD's CPU state from other
software, including the hosting Virtual-Machine Monitor (VMM), unless
explicitly shared by the TD itself.
There are 2 configurations for TDVF to upstream. See below link for
the definitions of the 2 configurations.
https://edk2.groups.io/g/devel/message/76367
This patch-set is to enable the basic feature of Config-B in OvmfPkg.
- Add a standalone IntelTdxX64.dsc to a TDX specific directory for a
*full* feature TDVF. (Align with existing SEV)
- IntelTdx.dsc includes Tdx/Legacy OVMF basic boot capability. The
final binary can run on Tdx/Legacy OVMF.
- PEI phase is skipped.
By design in Config-B there should be more advanced features, such as:
- RTMR based measurement and measure boot.
- Remove unnecessary drivers to reduce attack surface, such as
network stack.
To make the code review more efficiency, Config-B is split into 2 waves:
- Basic feature of Config-B
- Advanced feature of Config-B
This patch contains 2 files (IntelTdxX64.dsc/IntelTdxX64.fdf) which
enable the basic feature of Config-B. In the waves of Advanced feature
of Config-B, we will re-visit these 2 files.
TDX_PEI_LESS_BOOT is defined in IntelTdxX64.dsc to indicate it boots up
without PEI phase.

I think here are opportunities to make the differences between PEI and
PEI-less boot even smaller, by:
(1) Allocate a PlatformInfoHob also when using PEI boot workflow.
(2) Switch PlatformInitLib functions like PlatformGetFirstNonAddress() to
receive a PlatformInfoHob pointer so they can update the HOB
directly.
(3) Add more platform info variables to PlatformInfoHob
(FirstNonAddress, PhysMemAddressWidth for example).
But I guess that kind of improvements can also be done incrementally
after getting this upstream. It's also easier to test that kind of
changes when we have both PEI and PEI-less variants present in the
upstream repo. So I'm fine with deferring these changes for now.
Beside that: The name TdxStartupLib doesn't reflect reality any more,
we should give it a better name.
take care,
Gerd

Another thing we can probably simplify when we use a PlatformInfoHob in

Will TDX support secure boot? If not then this config switch can simply
be dropped (and the checks for SECURE_BOOT_ENABLE too).

Don't like it too much, but don't have a better idea.
In any case clearly better than TdxStartupLib.
