I'm not sure this sentence above makes sense since the thread pools
are just a threading mechanism, not a communication mechanism.  Maybe
you want to drop the sentence if you have to submit a new version.

let me clarify : ... is based on submitting tasks to thread pools. Better?


Doesn't the backend submit tasks to the host TPM from the thread pools?

Where is TPM_MODEL_TPM_TIS defined?



It's auto-generated from the qapi-schema.json.


Ah, I thought maybe that was it after I commented.
