OP-TEE SPMC implementation
==========================
Introduction
------------
### OP-TEE SPMC implementation
This document describes the OP-TEE SPMC implementation. This
implementation is used to support the Trusted Services PSA SPs. The PSA
SPs are based on the Arm FF-A specifications. The OP-TEE SPMC can be
used as a reference S-EL1 implementation and the Trusted Service can be
used a reference S-EL0 SP implementations.
### FF-A
Arm Firmware Framework for Arm A-profile (FF-A) is a framework designed
to standardize the communication between the various software images.
Including the communication between the various software images in the
Secure world and Normal world. The current release of the OP-TEE SPMC is
based around the [FF-A v1.0
spec](https://developer.arm.com/documentation/den0077/latest.)
### OP-TEE
OP-TEE is an open source Trusted Execution Environment (TEE)
implementing the Arm TrustZone technology. More information can be found
at [readthedocs](https://optee.readthedocs.io/en/latest/) OP-TEE can run both as a S-EL1 SP or as the S-EL1 SPMC.
This document describes OP-TEE as a S-El1 SPMC. The current mainline
OP-TEE version can be found [here](https://github.com/OP-TEE/optee_os)
### Trusted Services
The Trusted Services project provides a framework for developing and
deploying device Root Of Trust (RoT) services across a range of secure
processing environments such as those provided by OP-TEE and Hafnium.
More information about Trusted Service can be found at
[Trusted-Services](https://trusted-services.readthedocs.io/en/latest/)
Current Status
--------------
Currently the mainline OP-TEE SPMC is not yet fully compliant with the
FF-A V1.0 spec. It also doesn\'t support all of the Trusted Services
SPs.
### SPMC status
OP-TEE mainline SPMC FF-A status:
| Description | Status|
| --- | ----------- |
|SP loading | Supported |
|SP messaging | Supported |
|Manifest file | Not Supported |
|Memory management | Supported |
|Interrupts | Not supported |
OP-TEE mainline SPMC FF-A messages status:
------------------------------ -------------------------
|------------------------------|-----------|
| FFA_ERROR | Supported|
| FFA_SUCCESS | Supported|
| FFA_INTERRUPT | Not supported|
| FFA_VERSION | Supported|
| FFA_FEATURES | Supported|
| FFA_RX_RELEASE | Supported|
| FFA_RXTX_MAP | Supported|
| FFA_RXTX_UNMAP | Supported|
| FFA_PARTITION_INFO\_GET | Supported|
| FFA_ID_GET | Supported|
| FFA_MSG_WAIT | Supported|
| FFA_YIELD | Not supported|

| FFA_MEM_RETRIEVE_RESP | Supported|
| FFA_MEM_RELINQUISH | Supported|
| FFA_MEM_RECLAIM | Supported|
[^1]: Device memory is not yet supported.
### Trusted Service status
Currently not all Trusted Service functionality is supported when using
the OP-TEE SPMC. We are planning to support all functionality over time.
Currently the OP-TEE SPMC supports the following PSA Trusted Services
SPs:
--------------------------- --------------------------------------------------------------------
|----------------------------|--------|
|internal-trusted-storage: |Supported|
|protected-storage: |Supported|
|crypto: |Supported with mock backend. A hardware trngs is not yet supported|
|attestation: |Not yet supported|
|smm-gateway: |Not yet supported|
Build
-----
The build process is based around the [OP-TEE build
process](https://optee.readthedocs.io/en/latest/building/gits/build.html)
with some extra steps.
### Requirements:
- The Trusted Services project has some extra
[requirements](https://trusted-services.readthedocs.io/en/latest/developer/software-requirements.html)
from OP-TEE. It mainly depends on cmake.
- The current system uses the Arm FVP to run the test environment. The
latest version can be found at
[developer.arm.com](https://developer.arm.com/-/media/Files/downloads/ecosystem-models/FVP_Base_RevC-2xAEMvA_11.16_16.tgz)
The default path for FVP in the build scripts is set to
/opt/fvp/latest
### Build steps
Get the manifest file:
rm -rf optee
mkdir optee
cd optee
repo init -u https://review.trustedfirmware.org/OP-TEE/manifest -m psa-sp-fvp.xml -b topics/spmc_mainline
repo sync -j4 --no-clone-bundle
Build the OP-TEE image:
The OP-TEE build will default be configure to use mainline OP-TEE SPMC.
To be able to build OP-TEE mainline version, it might be needed to
change the SPMC\_VERSION to SPMC\_VERSION=github in build/fvp\_ffa.mk.
Build OP-TEE:
cd build
make toolchains
make
cd ..
Build TS apps:
make -C trusted-services/tools/b-test r-component-test-arm-linux \
r-psa-api-test-crypto-arm-linux \
r-psa-api-test-internal_trusted_storage-arm-linux \
r-psa-api-test-protected_storage-arm-linux \
r-ts-demo-arm-linux \
r-ts-service-test-arm-linux
Copy the TS apps to the shared directory:
cp -r trusted-services/tools/b-test/install/arm-linux shared
More info about building TS-apps can be found at the [Trusted Services
build
instructions](https://trusted-services.readthedocs.io/en/latest/developer/build-instructions.html)
Run fvp:
make -C build run-only
Set up the [fvp
environment](https://trusted-services.readthedocs.io/en/latest/environments/deployment-guides/fvp-deployment-guide.html?highlight=ts-service-test#deploying-service-level-tests):
cd /mnt/
sh load_module.sh
cp arm-linux/lib/libts.so.1 /usr/lib/
Run the PSA ServiceTests:
cd /mnt/arm-linux/bin
./ts-service-test -v -sg ItsServiceTests
./ts-service-test -v -sg PsServiceTests
./ts-service-test -v -sg CryptoKeyDerivationServicePackedcTests
./ts-service-test -v -sg CryptoMacServicePackedcTests
./ts-service-test -v -sg CryptoCipherServicePackedcTests
./ts-service-test -v -sg CryptoHashServicePackedcTests
./ts-service-test -v -sg CryptoServiceProtobufTests
./ts-service-test -v -sg CryptoServiceLimitTests
./ts-service-test -v -sg DiscoveryServiceTests
./ts-service-test -v -sg CryptoServicePackedcTests
Currently the attestation and fail due the lack of the attestation SP
support.
