Hi all,
I just ran the Linux txt-stat tool (which comes with tboot) on a system which has an IceLake CPU and a 495 Series PCH, and am seeing the following output:

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?
