IMO, someone needs to propose a specific user space API that provides this capability. Personally, I don't think MADs provide the desired interface. I suggested looking at the libibverbs async events, but I didn't take the time to look at the details of how well that API would fit. It's used to report client_reregister events, so using it to report notifications doesn't seem too out of line. What's missing is a mechanism to register for the event, which does map better to umad. Maybe the kernel user_mad module snoops MADs and reacts accordingly. Isn't access to the umad interface usually privileged? If so, is that acceptable for the anticipated usage? - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
