+# gdsp_remoteproc Test
+
+© Qualcomm Technologies, Inc. and/or its subsidiaries.

+
+## Overview
+
+This test case validates the functionality of the **GPDSP (General Purpose DSP)** firmware loading and control on the **Lemans** platform. It specifically targets:
+
+- `gpdsp0`
+- `gpdsp1`
+
+The script ensures that each GPDSP remote processor:
+- Is currently running
+- Can be stopped successfully
+- Can be restarted and returns to the running state
+
+This is essential for verifying the stability and control of DSP subsystems on Qualcomm-based platforms.
+
+## Usage
+
+### Instructions
+
+1. **Transfer the Script**: Use `scp` or any file transfer method to copy the script to the Lemans target device.
+2. **Navigate to the Script Directory**: SSH into the device and go to the directory where the script is located.
+3. **Run the Script**:
+   ```sh
+   ./run.sh
+   ```
+   ---
+   #### Quick Example
+```
+git clone <this-repo>
+cd <this-repo>
+scp -r common Runner user@target_device_ip:<Path in device>
+ssh user@target_device_ip
+cd <Path in device>/Runner && ./run-test.sh gdsp_remoteproc
+```
+---
+## Prerequisites
+1. The device must expose `/sys/class/remoteproc/remoteproc*/firmware and /state` interfaces.
+2. Root access may be required to write to remoteproc state files.
+3. The firmware names must include gpdsp0 and gpdsp1.
+ ---
+ ## Result Format
+Test result will be saved in `gdsp_remoteproc.res` as:  
+## Output
+A .res file is generated in the same directory:
+
+`gdsp_remoteproc PASS`  OR   `gdsp_remoteproc FAIL`
