hi all,
not, sure, if it is an issue with the rt kernel, but the branch hint in
rt_prio appears to go to the wrong direction, when profiling on my machine:
static inline int rt_prio(int prio)
{
if (unlikely(prio < MAX_RT_PRIO))
return 1;
return 0;
}
would be nice, if someone with more insight in the scheduler could have
a look at this ...
thanks, tim
