> qib, mlx4 are fine. mlx5 should be as well I would think (I don't have that > hardware.) I have no specifics to add, but I keep running into systems, even today, where the 64 bit counters don't work. The MAD might be there, but several counters are wired to 0. Not sure exactly which HW though. Mellanox should really confirm this for their hardware matrix. FWIW, I also hate the sysfs counters that reflect the PMA, these would be much better are free running, wrapping, non-resetting counters unrelated to the PMA. Something that doesn't zero after the SM samples it. Sounds like qib, hif, rdmavt can trivially fix this, and should, IMHO.
