Test Reports

Introduction

This section provides detailed test reports for each release of Linux for ADSP-SC5xx processors. These reports document the verification and validation testing performed on various hardware platforms and software components, helping you understand what features have been tested and their status across different board configurations.

Each test report includes comprehensive results for key subsystems including audio drivers, inter-processor communication (RPMsg), peripherals, networking, and more. The reports indicate which features are verified, known limitations, and board-specific considerations.

Why test reports matter:

  • Verify that critical features work on your specific hardware configuration

  • Understand known issues and workarounds before deployment

  • Plan your testing strategy based on verified functionality

  • Track regression fixes and improvements across releases

  • Make informed decisions about board selection for your project

Note

Test reports are cumulative for minor releases (e.g., 5.0.x). Regressions specific to patch releases are explicitly noted within each report.

Understanding Test Results

Test reports use the following symbols to indicate component status:

  • ✅ - Verified working on this platform

  • ➖ - Not applicable or not tested on this platform

  • N/A - Hardware-specific feature not available on this board

  • Known Issue - Feature has known limitations (see notes in report)

  • virtio RPMsg for ARM-SHARC communication

  • Message passing and shared memory

Core Functionality

  • Common Clock Framework

  • Crypto Framework and hardware acceleration

  • Pinctrl and GPIO subsystems

  • Reset controllers

Storage and Memory

  • eMMC/SD card interfaces

  • QSPI/SPI flash support

  • DMA engines

Networking

  • Secure boot (where applicable)

  • Boot mode switching

Using Test Reports

Before deployment:

  1. Check the test report for your target hardware platform

  2. Verify that your required features are marked as tested

  3. Review any known issues or limitations

  4. Plan workarounds for untested or N/A features

During development:

  • Use test reports to validate your custom builds

  • Reference testing methodology for your own validation

  • Report discrepancies or regressions to the development team

For issue reporting:

When reporting issues, include:

  • Your release version and target board

  • Reference to the relevant test report

  • Whether the issue reproduces on a known-good configuration
