Where does one get seamldr?

[rnertney]

I found on the Intel site.

However, the build instructions are not the clearest. I'm able to build the p-seam-loader (same way as my Issue #1), but building np-seam-loader requires windows-based Visual studio. I'm instructed to open a command prompt to the Projects\Server\Emr\Seamldr folder, and then run make.

make doesn't resolve on windows. opening any of the vcxproj or sln files in Visual Studio on Windows also can't resolve all of the errors.

What are the steps needed to rebuild the seam loader so that I can launch TDX1.5 (when my UEFI doesn't have the 1.5 support builtin)?

Hi Rob, currently SEAMLDR is not open-source yet. You can file your question through the Intel TDX landing page - https://www.intel.com/content/www/us/en/developer/tools/trust-domain-extensions/overview.html

Also, the build option provides the ability to compare the publicly exposed source code to the officially released binary.
To run the TDX Module it is required to use the official signed binaries released by Intel. Intel does not provide an environment to run TDX with non-signed binaries.

How can I utilize the right-most path for loading the 1.5 TDX module?

Are you suggesting that the support query on the Intel page is the route I should take to get the binary to utilize TDX 1.5 on my system? My SBIOS works for SPR TDX1.0, but I don't have an updated one where the UEFI will load SEAM->TDX1.5.

When you download the SEAM loader from the page, it just gives a bunch of projects to build.

Hi Rob,
Thank you again for showing interest in our TDX technology.
We can provide answers to TDX Module source code related questions on this GitHub page.
Questions about enabling activities should be directed through the enabling channels or through the official Intel TDX page:

Hi @iaxel77 that page suggests emailing [email protected], however that email bounces back

Verify input parameters, including the Intel TDX module’s signature structure.
Load the Intel TDX module image and verify its measurement.
Configure relevant regions and SEAM transfer VMCSs.
Return to the Virtual Machine Monitor (VMM) after successful loading and verification. This process ensures secure execution of trust domains within your system.

everything what's TDX software is exactly like this issue. I don't understand why intel provides almost 0 support to actually use the TDX hardware.

Is there anyone who managed to build the NP-SEAM Loader?
