Hi, If you want to access directly to user memory from kernel. You should use kiobuf mechanism. You can find more information about this subject into Device Driver book. I guess the chapter is MMAP.

I've decided to use the 'copy_from_user' function, but I don't know how I'm supposed to discover the userspace address I need to copy from. The data I want to get into the kernel is in a variable in a userspace function. -Jeremy -- ---------------------------- Jeremy C.
