Thank you, this was actually really important remark and reminder. OK so I think James' patch is stuck because of me, i.e. https://lore.kernel.org/linux-integrity/20200911114820.GB6877@xxxxxxxxxxxxxxx/ I'm sorry about this. The final final conclusion is that the way it exports PCRs is just fine. Can you test this version? https://patchwork.kernel.org/patch/11759729/ I can then add reviewd-by and apply it and you don't have to do any sort of stupid hacks. /Jarkkko
