Hello,

If anyone can take a look and merge these, it would be a start:

  * libtpms https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272972
  * swtpm https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272973

As I never read bhyve code before, I will start glancing it and trying 
to figure out stuff from Corvin's previous PR enabling pass-through for 
TPM. If anyone has any info to speed me up on this quest, please speak! 
Thank you!
