softirq-rx and rt_mutex_lock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



What i learned that - softirq cannot be put into sleep mode .( Am i right )  ?

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 ?

Thanks,
Ratheesh
