But so does the HMC I/O handler and the shutdown signal. The QDIO driver uses the undocumented SIGA instruction but it's there. There needs to be a mechanism where code (under the GPL) can be entered into the development stream without worrying about "lawyers at 10 paces". At the moment if the IBM team get things from the canonical source (i.e. kernel.org) they have no problems in using it and there are no questions asked. There seems to be a somewhat artificial distinction being drawn between this method and some form of direct donation. This is something that IBM management now needs to address: we're either doing the open source thing or not. No one's been burned yet so let's start getting a little more adventurous.
-----Original Message----- My guess? I haven't a clue, but I'd venture to say...never. It uses undocumented (SERVC) facilities and I don't know if IBM "legal" would look kindly on that.
