# Fuzzers for SurfaceFlinger

## Table of contents

+ [SurfaceFlinger](#SurfaceFlinger)



# <a name="SurfaceFlinger"></a> Fuzzer for SurfaceFlinger



SurfaceFlinger supports the following data sources:

1. Pixel Formats (parameter name: `defaultCompositionPixelFormat`)

2. Data Spaces (parameter name: `defaultCompositionDataspace`)

3. Rotations (parameter name: `internalDisplayOrientation`)

3. Surface composer tags (parameter name: `onTransact`)



You can find the possible values in the fuzzer's source code.



#### Steps to run

1. Build the fuzzer

```

  $ mm -j$(nproc) surfaceflinger_fuzzer

```

2. To run on device

```

  $ adb sync data

  $ adb shell /data/fuzz/arm64/surfaceflinger_fuzzer/surfaceflinger_fuzzer

```
