14 years agoIn the process of chaining dma, the smallest data dma_read & dma_write support in a TLP-unit is 4(DW). but actually, we find the data-playload of each TLP is not multiple of the 4(dw) sometimes, it will make mismatch of data in dma read then write .
Ask: What shouled I do to make sure the data-length is multiple of 4 in DT(Descriptor -table), and also with the data-length of each TLP?
