Add element-wise unary ops needed by Qwen 3.5's DeltaNet linear attention layers. These ops follow the existing unary-ops pattern with VTCM DMA double-buffering. - neg: negate via scale by -1.0 - exp: uses existing hvx_exp_f32 HVX intrinsics - sigmoid: uses existing hvx_sigmoid_f32_aa HVX intrinsics - softplus: log(1 + exp(x)) scalar fallback - CONT reuses the existing CPY infrastructure since making a tensor contiguous is equivalent to a same-type copy. - REPEAT implements tiled memory copy with multi-threaded execution via the worker pool, supporting f32 and f16 types. The kernel parallelizes across output rows and uses memcpy for each tile. Co-authored-by: Max Krasnyansky <maxk@qti.qualcomm.com> |
