No Sapphire Rapids Xeon supports TDX outside of major hyperscalers

[matti]

TDX support is coming in Emerald Rapids: https://www.techpowerup.com/304114/intel-xeon-sapphire-rapids-to-be-quickly-joined-by-emerald-rapids-granite-rapids-and-sierra-forest-in-the-next-two-years

The README is misleading with "Please contact Intel sales representative for on-premise bare metal server or processor or please refer What Intel® Xeon Processors Support for Intel® Trust Domain Extensions (Intel® TDX)?" - there is no server or processor that anybody else than a major cloud vendor has access to.

@matti we updated README.md for hardware availability, please take a look.

@kenplusplus looks good. Now I just wonder why I needed to push so hard on this to get a straight answer.

[TaihuLight]

@kenplusplus Apart from 4th Gen Intel Xeon Scalable processors, does Intel Core processors like i7-10700K and i7-13700K support TDX?
As their specifications contain "Intel® Trusted Execution Technology" , Or this refers to support SGX?

[matti]

@TaihuLight only upcoming xeon cpus will support.

[matti]

and yes, that refers to SGX

[TaihuLight]

Intel Trusted Execute Technology means Intel TXT instead of Intel SGX.
