Subject: [RFC PATCH v2 00/17] TDX KVM selftests
Date: Tue, 30 Aug 2022 22:19:43 +0000 [thread overview]
Message-ID: <20220830222000.709028-1-sagis@google.com> (raw)
Hello,
This is v2 of the patch series for TDX selftests.
It is based on v5.19-rc8 and Intel's V8 of the TDX host patches which
was proposed in https://lkml.org/lkml/2022/8/8/877
The tree can be found at
https://github.com/googleprodkernel/linux-cc/tree/selftests
Major changes vrom v1:
- rebased to v5.19
- added helpers for success and failure reporting
- added additional test cases
---
TDX stands for Trust Domain Extensions which isolates VMs from the
virtual-machine manager (VMM)/hypervisor and any other software on the
platform.
Intel has recently submitted a set of RFC patches for KVM support for
TDX and more information can be found on the latest TDX Support
Patches: https://lkml.org/lkml/2022/8/8/877
Due to the nature of the confidential computing environment that TDX
provides, it is very difficult to verify/test the KVM support. TDX
requires UEFI and the guest kernel to be enlightened which are all under
development.
We are working on a set of selftests to close this gap and be able to
verify the KVM functionality to support TDX lifecycle and GHCI [1]
interface.
We are looking for any feedback on:
- Patch series itself
- Any suggestion on how we should approach testing TDX functionality.
Does selftests seems reasonable or should we switch to using KVM
unit tests. I would be happy to get some perspective on how KVM unit
tests can help us more.
- Any test case or scenario that we should add.
- Anything else I have not thought of yet.
Current patch series provide the following capabilities:
- Provide helper functions to create a TD (Trusted Domain) using the KVM
ioctls
- Provide helper functions to create a guest image that can include any
testing code
- Provide helper functions and wrapper functions to write testing code
using GHCI interface
- Add a test case that verifies TDX life cycle
- Add a test case that verifies TDX GHCI port IO
TODOs:
- Use existing function to create page tables dynamically
(ie __virt_pg_map())
- Remove arbitrary defined magic numbers for data structure offsets
- Add TDVMCALL for error reporting
- Add additional test cases as some listed below
- Add #VE handlers to help testing more complicated test cases
