No particular reason, it just didn't seem likely to be useful on other HCA drivers. I can redo the patches that way, if people think it's the right thing to do. | > Yes, this is what I'm working on. | > The patch is the only change outside of the hw/qib/ directory. | > Do you want to see a preview of the sysfs code? | | I think the earlier you can post the whole driver, the sooner you'll get | it upstream. Yeah, we know... Schedule and people conflicts have slowed this down. We want to do it, and soon. And yes, the ib_ipath is being fully deprecated. The "full set" of patches that adds ib_qib upstream will include a subset that drops ib_ipath.
