No, I didn't try it. I just wanted to ask before I got started. Thanks that answers everything.
Any body know about the issue of assigning a process a region of physical memory to use for it's malloc and free? I'd like to just have the process call through to a UIO driver with an ioctl, and then once that's done it gets all it's memory from a specific region.
UIO drivers do not support ioctl, why would you need/want that? What's wrong with just using the correct mmap/munmap logic that UIO userspace drivers use today? thanks, greg k-h
