SEXIT

John_M_2 — Fri, 15 Aug 2014 15:36:13 GMT

I'm booting tboot to a 3.11.10 linux kernel and it is indeed booting and pcrs, including 17,18 and 19 are being extended. Perhaps I just don't understand the sequencing - the part that has me perplexed is where tboot goes into SENTER and then starts over again and succeeds - although SEXIT is never run - specifically this section. I guess my question is - why would it restart tboot?

The restart seems normal to

The restart seems normal to me given the actions in the first tboot run are different than the second.. First gets to GETSEC[SENTER} and the second one moves on and gets to GETSEC[WAKEUP]. But confirming that - will get back to you.

Ok - well works as designed

Ok - well works as designed is perfectly fine - but I guess I need to read the docs closer - I thought it was going to run from SENTER to WAKEUP in one shot - I see the processors all doing the SIPI wakeup.

Also - when I've seen other logs I don't believe I've seen this action - is it just that they aren't that complete usually?
