No credits? 'Scuse me but thats not excusable, PM needs to understand TANSTAAFL. > > Every bit of AMD silicon we touched ran under 25uS on the latency > test. Just for fun we had a few tweaked <4uS max jitter. This is not an rtai kernel, but 3.16.0-0.bpo.4-amd64. latencytest is running here right now, and while the 25 u-s loop last interval displayed is consistently in the 600ns area, the Max Jitter is horrible at 10050977, and Max Interval of 10075977 which is reason enough I'd never in my right mind ever attempt to drive machinery with it without a 5i25 or better card doing the stepper generation, even then 100 milliseconds of lag would trigger the cards WDT, and quite justifiably so. > IME can't be turned off since for security reasons.
