As of today can we do this:
1. drivers/char/tpm (C code)
2. drivers/char/tpm/protocol (imported tpm2_protocol)
?
And then build FFI from C to Rust for building commands that we need today etc.
There's one particular challenge where this could help: early boot code for D-RTM (i.e., Trenchboot) as given my crate is just a thing in stack with no deps, it could be linked also to that payload.
#linux #kernel #rust #tpm

This would be much better integration step for TPM2 than having a separate driver on Rust side. We could start with tpm2-cmd1/cmd2, then move on to tpm2-space.c i.e. get all structural processing inside Rust.
tpm2_protocol is light on definitions and should not need any kernel specific Rust shenanigans.
Consider it as value like integer but just a bit more complex internaal represention but in the end it is just a value.
