hi all, i am developing a data acquiring program on rtlinux 3.1,and need to tranmit a large amount of data between the rt process and non_rt process at high speed,so try to find the most efficient way of communication. After trying fifo,mbuff and share memory pool (putting aside a block of physical memory at boot time then access the pointer directly), the performance shows that the fifo cann't meet the requirement, but the differences between the mbuff and share memory pool are still unclear. It will be appreciated if who can offer some experience about this. Thanks
