What is the userspace app? If I were you I would keep things in the kernel since FPGA are such slow things... I think u have to directly manipulate your packet data from the FPGA memory. What does the FPGA device do? And why are you so insistent on userspace? The context switch overhead between userspace and kernel is just too high to justify your stance... regards, Girish -- Kernelnewbies: Help each other learn about the Linux kernel.
