Hi,
I'm porting an app from RTAI to Xenomai, and when it came to the
rt_printk function, I had to replace it with plain printk (the
xnarch_log* functions all use printk).
What I want to know if:
1- Is totally safe to call the standard kernel printk function from a
real time task?
Yes.
2- Even if it's safe, can it affect the performance of a real time task?
(or can it block under *any* conceivable condition?)
No.
Thanks.
Nacho.
