QUICK START:
------------
To run all tests:
    cd <path-to-test_apps>
    ./run_all_tests.sh

To run individual test:
    ./build/valu_heavy/valu_heavy

To rebuild:
    cd build
    make clean
    make -j$(nproc)

DOCUMENTATION:
--------------
- README.md        - Comprehensive documentation
- QUICKSTART.md    - Quick reference guide
- This file        - Build success summary

INFRASTRUCTURE:
---------------
Common infrastructure provides:
- HIP error checking macros (HIP_CHECK, HIP_CHECK_LAST)
- Device memory management utilities
- Test framework base class with timing
- Kernel runner helper class
- Result verification utilities

TARGET HARDWARE BLOCKS:
-----------------------
- SQ (Shader Quad / Compute Unit)
  * VALU instructions
  * SALU instructions
  * SMEM instructions
  * FLAT instructions
  * LDS operations

- GL2C (L2 Cache)
  * Cache hits/misses
  * Transaction sizes
  * Memory traffic

- TA (Texture Addresser)
  * Memory fetches
  * Buffer operations

- GRBM (Graphics Register Bus Manager)
  * GPU activity
  * Wait states
  * Stalls

BUILD CONFIGURATION:
--------------------
- HIP Path: /opt/rocm
- HIP Compiler: Clang 20.0.0
- HIP Standard: C++17
- Build System: CMake 3.16+
- Parallel Jobs: 8

SUCCESS CRITERIA MET:
---------------------
✓ All tests compile without errors
✓ All tests link successfully
✓ CMake build system works correctly
✓ All executables are runnable
✓ Documentation is complete
✓ Run script is executable

NEXT STEPS:
-----------
1. Run the test suite to verify GPU functionality:
   ./run_all_tests.sh

2. Profile individual tests with perf:
   perf stat -e amd_gpu/SQ_INSTS_VALU/ ./build/valu_heavy/valu_heavy

3. Use tests to validate performance counter implementation

4. Integrate with perf-dkms module testing workflow
