Hi all,
I just ran txt-stat on a system which has an IceLake CPU and a 495
Series PCH, and am seeing the following output:
Intel(r) TXT Configuration Registers:

unable to find TBOOT log
I'm seeing that the SENTER.DONE.STS and SEXIT.DONE.STS bits are both
set. If I understood right, this doesn't make sense since they signal
whether all the threads are running the code within the MLE or not
(I'm not running an MLE here). In addition, the DID reported by
TXT.DIDVID doesn't match that of my PCH (which is 0x3482). Am I doing
something wrong here?
