Build and run tests on OP-TEE reference integration for FVP

The Linux based build maintained by the OP-TEE project is used as the reference integration for testing trusted service deployments on a simulated hardware platform. Service providers deployed within secure partitions are tested using test executables that run as user-space programs under Linux. Test cases interact with trusted service providers using standard service access protocols, carried by FF-A based messages.

The test executables most often used for service level testing on hardware platforms are:

ts-service-test - contains a set of service-level end-to-end tests. Discovers and communicates with service providers using libts.

psa-api-test - PSA functional API conformance tests (from external project). Also uses libts.

This method uses the makefiles from the op-tee/build repository.

Before you start

Before attempting to run tests on the FVP simulation, the OP-TEE reference integration needs to be built and run. Read the following guides to understand how to do this:

OP-TEE build and run instructions, see: Deploying trusted services in S-EL0 Secure Partitions under OP-TEE

Instructions for loading and running user-space programs on FVP: Running user-space programs on FVP

Build the Linux application binaries

From the root directory of the workspace, enter the following to build the test applications:

make -C build ffa-test-all

Run ts-service-test

From the root directory of the workspace, enter:

FVP_PATH=../Base_RevC_AEMvA_pkg/models/Linux64_GCC-9.3 make -C build run-only

Once it boots to the login prompt, log in as root and from the FVP terminal, enter:

cd /mnt/host
cp -vat /usr out/ts-install/arm-linux/lib out/ts-install/arm-linux/bin
out/linux-arm-ffa-tee/load_module.sh
out/linux-arm-ffa-user/load_module.sh
ts-service-test -v

Use the same flow for other user-space programs. Check the output of the cp command executed to see executables copied under /usr/bin.

Build SPMC tests

Trusted Services includes S-EL0 tests SPs for validating the SPMC’s behavior by invoking various FF-A interfaces. These tests require OP-TEE’s xtest for starting them from the normal world. xtest uses linux-arm-ffa-user for accessing the FF-A layer. Building the SPMC tests uses the same build system but with the SPMC_TEST=y configuration:

make -C build SPMC_TEST=y all

Note

This build configuration only contains the SPMC test SPs and it does not include any of the Services.

See OP-TEE SPMC tests for further information.

Run SPMC tests

From the root directory of the workspace, enter:

FVP_PATH=../Base_RevC_AEMvA_pkg/models/Linux64_GCC-9.3 make -C build run-only

Once it boots to the login prompt, log in as root and from the FVP terminal, enter:

cd /mnt/host
out/linux-arm-ffa-user/load_module.sh
xtest -t ffa_spmc
