I heard from Himmelblau developers that they are basing their work heavily on tpmrm0, which made me of course happy, as it is one of my contributions some years ago :-)
When I worked on that feature in the Spring of 2017 I thought that nobody will use it, as it is just way too niche, and I could not fully convice myself that it would bring much useful application on top of /dev/tpm0. And there was already IBMTSS and Intel TSS2.
James Bottomley did a lot for this one
in particular tricky dev management code and extended swapper I had put together also for sessions, in addition to objects.
Definitely gives me the needed boost after holiday season to look more into Himmeblau project and gives some faith that I could be useful somehow over time in that ecosystem :-)
