+# Coresight TGU Enable/Disable Test
+
+## Overview
+This test validates the **Trace Generation Unit (TGU)** drivers in the Coresight subsystem. It ensures that TGUs can be enabled and disabled successfully when paired with standard sinks (ETR and ETF).
+
+## Test Goals
+
+- Validate the functionality of TGU drivers in the Coresight subsystem.
+- Ensure TGUs can be successfully enabled and disabled via sysfs.
+- Verify proper operation when TGUs are paired and routed to standard sinks (ETR and ETF).
+- Confirm that enabling/disabling TGUs does not return unexpected I/O errors.
+
+## Prerequisites
+
+- Kernel must be built with Coresight support. 
+- `sysfs` access to `/sys/bus/coresight/devices/`.
+- Root priviledges needed.
+
+## Script Location
+
+```
+Runner/suites/Kernel/DEBUG/TGU-Enable-Disable/run.sh
+```
+
+## Files
+
+- `run.sh` - Main test script
+- `TGU-Enable-Disable.res` - Summary result file with PASS/FAIL
+- `TGU-Enable-Disable.log` - Full execution log.
+
+## How it Works
+1.  **Discovery**:
+    *   Scans `/sys/bus/coresight/devices/` for devices matching `tgu` (e.g., `coresight-tgu`).
+    *   Identifies available sinks (`tmc_etr`, `tmc_etf`, or `coresight-tmc-*` variants).
+2.  **Outer Loop (Sinks)**:
+    *   Iterates through available sinks (ETR, then ETF).
+    *   Resets the Coresight topology (`reset_source_sink`).
+    *   Enables the current sink.
+3.  **Inner Loop (TGUs)**:
+    *   **Enable**: Writes `1` to `enable_tgu`.
+    *   **Verify**: Checks the exit code of the write operation.
+    *   **Disable**: Writes `0` to `enable_tgu`.
+    *   **Verify**: Checks the exit code.
+4.  **Cleanup**: Disables the sink before the next iteration.
+
+## Usage
+
+Run the script directly. No iterations or special arguments are required for this basic test.
+
+```bash
+./run.sh
+```
+
+## Example Output
+
+```
+[INFO] 2026-03-24 05:58:32 - -----------------------------------------------------------------------------------------
+[INFO] 2026-03-24 05:58:32 - -------------------Starting TGU-Enable-Disable Testcase----------------------------
+[WARN] 2026-03-24 05:58:32 - No TGU (Trace Generation Unit) devices found. Skipping test.
+[INFO] 2026-03-24 05:58:32 - Cleaning up...
+[INFO] 2026-03-24 05:58:32 - -------------------TGU-Enable-Disable Testcase Finished----------------------------
+```
+
+## Return Code
+
+- `0` — All TGUs are enabled and disabled successfully across all tested sinks
+- `1` — One or more TGUs failed to enable or disable
+
+## Integration in CI
+
+- Can be run standalone or via LAVA
+- Result file `TGU-Enable-Disable.res` will be parsed by `result_parse.sh`
+
+## Notes
+
+- The test systematically pairs TGUs with different sinks to ensure that the Coresight routing topology functions correctly for each configuration.
