I would like to ask whether calling wake_up_interruptible is OK in RTL and
RTAI from real time ISR (or RT task)? I remember some discussion where Paolo
stated it is possible in RTAI.
Another question is whether I can use standard wake_up_interruptible() kernel
call, or I have to change it to some other function?
I have the following situation in mind: I have normal Linux interrupt
handler, packing data into static buffer. It then calls
wake_up_interruptible. Can I just register this handler as RT IRQ handler
without any modification? When the woken up task will run? On next regular
timer tick? Or after any other soft Linux interrupt (when BH is processed)?
I hope the answer can be added to:
