This page describes how to get and build the OP-TEE benchmark framework. For the architectural details, please refer to the benchmark_framework page instead.
The benchmark framework spans across different architectural layers and therefore it doesn’t make much sense to build it as a standalone build. Therefore we only give guidance telling how to enable it in full OP-TEE developer builds. For general instructions for full OP-TEE developer builds, please refer to instructions at the build page. But otherwise follow the instructions below to enable the benchmark framework.
Enable the benchmark framework¶
Before using Benchmark framework, OP-TEE should be rebuilt with the
CFG_TEE_BENCHMARK flag enabled so that the benchmark framework will be
enabled in all architectural layers. You do that by:
$ cd <optee-project>/build $ make CFG_TEE_BENCHMARK=y
Benchmark application usage¶
When everything has been built (flashed) and you have booted up the device and you have a console ready to accept command, then the next step is to run the actual benchmark application together with the host/TA application you intend to benchmark. You do this my giving the host applicant as argument to the optee_benchmark binary. Let’s say for example that you intend to benchmark the hello_world example. Then you invoke the benchmark like this:
$ benchmark hello_world
When client_app finish the execution, optee_benchmark will generate
<client_app>.ts time stamp data file in the same directory, where Client
Application is stored (i.e., relative to hello_world in this case).
