In qm_qp_ctx_cfg(), "sqc" and "aeqc" are mapped to streaming DMA: eqc_dma = dma_map_single(..., eqc, ...); ...... aeqc_dma = dma_map_single(..., aeqc, ...); Then "sqc" and "aeqc" are accessed at many places, such as: eqc->base_l = cpu_to_le32(lower_32_bits(qm->eqe_dma)); eqc->base_h = cpu_to_le32(upper_32_bits(qm->eqe_dma)); ...... aeqc->base_l = cpu_to_le32(lower_32_bits(qm->aeqe_dma)); aeqc->base_h = cpu_to_le32(upper_32_bits(qm->aeqe_dma)); These accesses may cause data inconsistency between CPU cache and hardware. I am not sure how to properly fix this problem, and thus I only report it. Best wishes, Jia-Ju Bai
