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? 2- Even if it's safe, can it affect the performance of a real time task? (or can it block under *any* conceivable condition?) Thanks. Nacho.
