…ld integration Add Ascend platform scaffolding: - `device_.h`: `DeviceEnabled<kAscend>` specialization - `data_type_.h`: `toAclDtype()`, `isIntegerDtype()` - `common.h`: `buildAclTensor()` with optional transpose - `workspace_pool_.h`: stream-keyed workspace allocator - `runtime_.h`: `Runtime<kAscend>` (Malloc, Free, Memcpy, Memset) - 5 new operator base classes (AddRmsNorm, FlashAttention, Matmul, ReshapeAndCache, RotaryEmbedding) Integrate into CMake build system, Python binding generation (stream + optional tensor support), and examples runtime API.
…emove missing include - Wrap `aclrtMemcpy` (5-arg) and `aclrtMemset` (4-arg) in lambdas to match the generic 4-arg / 3-arg calling convention used by examples. - Assert `aclrtMalloc` return value in `WorkspacePool::ensure()`. - Remove `ascend/gemm/kernel.h` include from `runtime_api.h` (file does not exist until the kernels commit).
- Add Ascend GEMM specialization using `aclnnAddmm`/`aclnnBaddbmm`. - Add `get_npu_stream()` helper and NPU device detection in test utils. - Add `skip_unsupported_dtype` fixture for Ascend in conftest. - Update `runtime_api.h` with Ascend backend entry.
The `aclrtMalloc` call was the sole expression inside `assert()`, so it was compiled away in release builds (NDEBUG). This left the workspace buffer null, causing `aclnnAddmm` to return ACLNN_ERR_PARAM_NULLPTR (161001) for any operation that requires workspace (e.g. alpha != 1.0).
