Hi, I am currently testing crystal beach dma on x86-64 on linux. I have kernel version 2.6.32 on it. As per kernel documentation when dmatest module is inserted in /sys/module/dmatest/parameters/ files are created . However in this case files run and timeout are missing. So I am unable to start dmatest eventhough module is loaded Anyone has idea about it? Please help.
