All of the values varies likewise with or without the change to the kernel. I
mean even with vanilla (ie the one were none of the "available" wanted values
miss : 0, 1024, 2048, 3072.
min is around 7 and max around 22 in new_us-last_us and time_us-kast_time.
What is wrong with the results ? I mean I do not know what you check for and
why.
about the dma burst: its size is not fixed afaik, the transfer width is. Plus
the dma burst if too small a size wil be split into a sequence of single
transfers.</pre>
