Hi,
Assuming Isolation Level 1 and IPC backend, I’m using Attestation partition with SFN model with stateless handle and a custom Crypto partition using IPC model with stateless handle. My custom Crypto partition includes a PSA crypto wrapper
which defines all the PSA Crypto APIs to use HW crypto. We used IPC since we want to be able to support isolation level 2-3 in the future.
When the Attestation partition make calls to PSA Crypto (psa_hash_setup for example), should it use a psa_call() to the Crypto Partition? That is what I had expected since the crypto partition is IPC model but I’m seeing it call the PSA
crypto code directly. Also, it appears to provide client side psa_hash_operation_t directly to the psa_hash_setup which is expecting the full operation struct.
Is my configuration valid? How should it work?
