I noticed that too. I just added HIDMA_TRE_MEMCPY parameter to hidma_ll_set_transfer_params() function call from hidma_prep_dma_memcpy() and created a new hidma_prep_dma_memset() function very similar to memcpy with HIDMA_TRE_MEMSET call difference. My suggestion is to use kdiff or another visual tool to look at the change. Sinan -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
