Hello everybody, I am not sure if this is the right place to be asking this. If is not, I apologize for the inconvenience. Also, please tell me where is a better way to as these questions. I am trying to create a basic C code to test vmsplice + SPLICE_F_GIFT for moving memory pages between two processes without copying. I have followed the man pages and several recipes across the web, but I could not reproduce it yet. Basically, I am doing: Sending process: - malloc + memcpy for generating pages to transfer - vmsplice with SPLICE_F_GIFT sending over named pipe (in a loop) Receiving process: - Create mmaped file to receive the pages - splice with SPLICE_F_MOVE receiving from named pipe (in a loop) I have seen the SPLICE_F_MOVE being used on steal ops from the 'pipebuffer', but I couldn't find a way to call it from splice. Questions: It does what I think it does? (reassign memory pages from a process to another) If so, does page gifting still works? If so, is there a basic recipe to test it's workings? Thank you for reading, Leonardo Brás
