What i learned that - softirq cannot be put into sleep mode .( Am i right ) ?
Hello, Ratheesh, I'm adding linux-rt (the real-time linux mailing list, which is the more appropriate place to put this question first) to the cc list. Also note that linux-net is mostly a dead list, as you'll observe if you take a look at the archives, and netdev@xxxxxxxxxxxxxxx is the more appropriate mailing list for network development questions (i.e., search here first).
I am facing a problem in my RT linux . I used rt_mutex_lock to protect one critical section in softirq-rx code . There is some kernel crash happens in the critical section . PC- > my function in critical section LR -> rt_mutex_unlock . Why LR is rt_mutex unlock ? If rt_mutex_lock can sleep , softirq-rx may sleep ?
If you are running with the RT patchset (CONFIG_PREEMPT_RT), yes, irqs are now kernel threads. There is more information here: https://rt.wiki.kernel.org/index.php/Main_Page thanks, Nivedita -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
