Hi Jens,
When we rework MM in OP-TEE, would the SHM protocol, currently implemented in drivers/tee as a generic protocol (namely not specific to OP-TEE), be subject to some twicks?
Sorry, I don't understand, which protocol?
The NS side is expected to call MSG_GET_SHM_CONFIG at boot, and use the returned parameters to initialize the shm_pool module.
To be able to work with multiple VMs, are we open to tweaking the boot protocol when we rework the MM in OP-TEE and Gen TEE driver?
Yes, I don't see a problem with that if needed as long as we can keep backwards compatibility.
Thanks, Jens
