Add AMD_TRITON_NPU_TARGET env var for cross-compilation#46
Merged
Conversation
When set to 'npu1' or 'npu2', detect_npu_version() returns the specified target directly without querying xrt-smi. This enables AMD_TRITON_NPU_COMPILE_ONLY to work on machines without a matching local NPU device. Closes #42 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Pull request overview
Adds an explicit NPU target override via environment variable to enable cross-compilation workflows without requiring local NPU hardware detection.
Changes:
- Introduces
AMD_TRITON_NPU_TARGETto overridedetect_npu_version()and bypassxrt-smidevice querying. - Validates
AMD_TRITON_NPU_TARGETagainst supported internal NPU versions and raises a clearRuntimeErroron invalid values.
