that did it! just putting:
struct sched_param schp;
// set the process to realtime privs
memset(&schp, 0, sizeof(schp));
schp.sched_priority = sched_get_priority_max(SCHED_FIFO);
if (sched_setscheduler(0, SCHED_FIFO, &schp) != 0)
at the start of my processing thread loop seems to do the trick.
thanks! now i need to figure out about the running as root problem...
