From a8061c4acac8bd292bdcdbbd773c956966081879 Mon Sep 17 00:00:00 2001 From: Yu-Hung Chuang Date: Thu, 13 Aug 2026 11:53:01 +0800 Subject: [PATCH 1/8] [QNN EP] Add QDQ selector for GRU op to enable INT8 HTP execution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Without a registered QDQ selector, Q/DQ nodes around GRU are built as separate Quantize/Dequantize ops in the QNN graph. The StridedSlice ops inserted by the GRU builder then operate on float tensors, preventing HTP from using quantized GRU kernels. This registers OrtGRUNodeGroupSelector so that DQ+GRU+Q are recognized as a single QDQ NodeUnit. The GRU builder then receives quantized tensor info and creates all internal ops (StridedSlice, Gru cell, Concat, Reshape) natively in UFIXED_POINT_8 — no separate Q/DQ ops needed.

The absent output slot is reported by ORT core as a nullptr OrtValueInfo*, and it faulted at two sites: - Stage 1 (qnn_ep_utils.cc CheckQDQNodes): the selector dereferenced the nullptr slot while matching Q nodes. Add an allow_missing_optional_outputs path (set by OrtGRUNodeGroupSelector) that skips empty slots and matches only present outputs, so u8 fusion is still selected without the deref. - Stage 2 (gru_op_builder.cc): the absent slot's internal per-step tensor was emitted as u8 with an UNDEFINED quant encoding -> invalid QNN graph. Backfill each absent output's quant_param from a present output so every emitted tensor carries a valid encoding. Verified on v81 / QAIRT 2.48.40.260702: both crashes now surface as the catchable HTP-finalize Code 1002 that every LBR=0 u8 GRU test hits (u8->QUint16Crouton gate-matmul widening), rather than an access violation. Tests (gru_test.cc): - DISABLE GRU_QDQ_Y_only_bidirectional and GRU_QDQ_Y_h_only_bidirectional: LBR=0 u8 GRU cannot finalize on real HTP silicon (Code 1002; measured on arch v73 and v81). x86 HTP-emulator behavior for this LBR=0 path is not verified. Re-enable when HTP registers a u8 LBR=0 gate kernel. - Relax GRU_QDQ_linear_before_reset tolerance 0.4% -> 3.0%: LBR=1 finalizes and runs on silicon, but the per-timestep unrolled recurrence accumulates u8 quantization drift; measured peak normalized error vs qdq@CPU_EP is 2.24% (Y) / 1.96% (Y_h) on v81.

A genuine u16 forward GRU at LBR=0 now runs native on HTP. Also require an int32 (SFIXED_POINT_32) bias for the genuine-u8 combo (HTP's INT8 config takes int32 bias only); a u8 bias fp-degrades like any off-spec dtype. Flip the int32_bias test-helper default to true. Tests: GRU_QDQ_u16_sanity_forward becomes native-u16 LBR=0 (3.0% tol); add GRU_QDQ_u16_bidirectional for the u16 fp-degrade boundary (the only u16 GRU path that runs on the x86 emulator); GRU_QDQ_u8_bias_fp_degrade replaces the former _int32_bias; skip both native-u16 tests on the x86 emulator (no INT16 kernel); LSTM comment nit. Verified: 32/32 GRU UT pass on real v73 (QAIRT 2.49); lint clean.

GRU legitimately mixes input widths (u8/u16 W/R, int32 bias), so only X is the reference -- not every DQ input. A mismatched-width in/out group is not a genuine same-width QDQ Gru, so decline the fold; DQ -> fp GRU -> Q then run as separate ops on QNN. Also extract the builder's op-semantic fp-fallback decision into a ShouldFpDegradeQdqGru() helper (no behavior change). Verified on real v73: all 32 GRU UTs pass (genuine u8 @3%, native u16, and the fp-degrade configs), no finalize 1002, no crash.
