Hi All, We are running Linux on an embedded system(MIPS processor) that has no disk for swap. Also we are passing huge data structures from user to kernel space in our driver. Can we avoid copy-in's and make the driver use the virtual address from the kernel space. Our analysis is copy-in's is provided because the process can be swapped out. Also the virtual addresses we plan to use will not get used in interrupt context; hence we can use the virtual addresses directly. Are there any risks which we are unable to forecast?
