While not directly addressing Michael's work on the parport driver, I have pulled the latest from rtos-integration-preview1, built it on my 4-core AMD box, and run latency-test with all 16 combinations of base and servo thread on the 4 cores. I get lovely numbers. Rather than clot this list with my turgid prose I've posted my results and observations to my occasional Google Site https://sites.google.com/site/manisbutareed/linuxcnc-2-5/xenomai-user-threads Regards, Kent ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
