In this wiki, it demonstrates architecture of Linux Stack for Intel® Trust Domain Extensions(TDX) enabling in an end-to-end stack. It also introduces tools to setup stack and test TDX with measurement and attestation. tdx-tools keeps evolving along with kernel version. It supports kernel 5.15, kernel 5.19 and kernel 6.2. Please refer to corresponding tag for different kernel version support. All the following tools may vary based on different kernel version. Please make sure to use the corresponding tag aligned with kernel version.
| Tag | Kernel version | TDX Version | Descriptions |
|---|---|---|---|
| 2022ww44 | 5.15 | TDX 1.0 | |
| 2023ww01 | 5.19 | TDX 1.0 | Performance Optimizations |
| 2023ww15 | 6.2 | TDX 1.5 | Live Migration |
| 2023ww22 | 5.19.17 | TDX 1.0 | FDE, Amber Client, IMA |
| 2023ww27 | 6.2.16 | TDX 1.5 | vTPM, Live Migration+ |
| 2023ww41 | 6.2.16 | TDX 1.5 | Performance optimization, vTPM+, Live Migration+, CVE fix |
NOTE: Please refer the white paper Linux* Stacks for Intel® Trust Domain Extension 1.0 for how to use Linux Stack for Intel TDX 1.0.
