# KeyMint Benchmark
The KeyMint Benchmark is a standalone tool for measuring the performance of
KeyMint implementations.
## Building
Build:
`m VtsAidlKeyMintBenchmarkTest`
Transfer to device/emulator:
`adb sync data`
The benchmark executable will be located at
`data/benchmarktest/VtsAidlKeyMintBenchmarkTest` on the device.
## Usage
KeyMint Benchmark is built on [Google microbenchmark
library](https://github.com/google/benchmark). All of the commandline arguments
provided by the microbenchmark library are valid, such as
`--benchmark_filter=<regex>` or `benchmark_out_format={json|console|csv}`.
In addition to the command line arguments provided by microbenchmark,
`--service_name=<service_name>` is provided to allow specification of the KeyMint
fully qualified service name, e.g. specify
`--service_name=android.hardware.security.keymint.IKeyMintDevice/default` to
benchmark default implementation of KeyMint.
