We already discussed this at Plumbers. the problem is that the kernel itself needs access to the TPM (in both Linux and Windows as far as I can tell). If you put the RM in User Space, the kernel would either not have access or have some dependency on a user space process which is never a good idea. > as signle owner of /dev/tpm0 (enforced by single-open-/dev/tpm0). > Only alternative would be a RM inside the Kernel. Right, so that's what we now have with Jarkko's just posted patches.
