EFI TBOOT

The EFI TBOOT project is currently under development! EFI TBOOT is mostly a proof of concept at this point. It is not currently functional. It can be built and installed as an EFI boot loader. It only works in conjunction with Xen at the moment. The current development work is being done on Fedora 25 x64. The status as of March 14, 2017 is:
 – EFI TBOOT will boot, but it needs a few key strokes to get going (this is for debugging purposes).
 – EFI TBOOT will relocate itself to EFI runtime memory and setup a shared runtime variable with Xen.
 – EFI related configuration setup is done as well as standard TBOOT pre-launch configuration.
 – Xen is launched and has code to call EFI TBOOT back after EBS.
 – EFI TBOOT then does the SENTER successfully in the callback.
 – The post launch entry point is reached but the switch back to long mode is not working.

EFI TBOOT needs a number of platform support files used with TXT (called Authenticated Code Modules or ACMs). For convenience the packages can be gotten from the OpenXT mirror:
