The tag I use is 2023ww33.
2023ww33 is for TDX 1.0, and your kernel version is 5.19.17. The problem is that your TDX module is for TDX 1.5, which does not match the kernel, please check this.
[三 9月 13 12:04:49 2023] tdx: TDX module: vendor_id 0x8086, major_version 1, minor_version 5, build_date 20230323, build_num 481
The 5.19.17 version kernel is specified in 2023ww33. So I think I need to downgrade the tdx module. What should I do? Thanks in advance.
@henrysun007 Since your BIOS stitches TDX module 1.5, 2023ww27-update is recommended, where TDX kernel 6.2.16 and TDX QEMU 7.2.0 work well with TDX module 1.5 .
