You may also want to try the kernel function kill_proc that roughly corresponds
to kill(2). Actually I did not use it in an RT task but I expect it to work.
I used kill_proc to send a signal from a driver (i.e. kernel space) to a Linux
process. It works and looks like:
if(kill_proc(pid,signal,0)<0)
printk("kill_proc failed\n");
where pid and signal are the same as in kill(2). I don't remember what I
found out about the 3rd parameter.
Please drop us a line+source how have you solved your problem.
