I think software interrupts are used in Linux for system calls and nothing
else.
Why using system call is not an option here?
In case of software interrupt from user space there is no difference between
real-time interrupt handler and normal interrupt handler. In fact the whole
process looks almost like calling a subroutine going from protected to
supervisor mode.
I do not understand what do you want to achive using software interrupt.
