Conversation
This commit introduces full support for the Rockchip RK3588s platform, enabling NPU-accelerated inference for ASR tasks.
Key Changes:
- **Toolchain**: Added `cmake/toolchains/rk3588s.cmake` targeting aarch64-buildroot-linux-gnu.
- **Dependency**: Implemented `third_party/librknnrt` to manage NPU runtime libraries via FetchContent (Added v2.2.0 and v2.3.2 presets).
- **Build System**:
- Updated `CMakePresets.json` with RK3588s-specific mixins (GCC 11.3.0/13.3.0) and build configurations.
- Modified `third_party/sherpa-onnx` build logic to explicitly link against `LibRKNNRT` for NPU support.
- **Application**: Updated `asr-task-sherpa.cpp` default model paths to RK3588 streaming zipformer (NPU) models.
- **Validation**: Verified execution and inference stability on RK3588s hardware.
