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
