bounded interrupt latencies

Connected From This

We  ensure bounded  interrupt latencies  by  the standard
approach   of  introducing   a  few,   carefully  placed,
interrupt  points. On detection  of a  pending interrupt,
the kernel  explicitly returns through  the function call
stack to  the ker- nel/user boundary and  responds to the
interrupt.  It  then  restarts  the  original  operation,
including   reestablishing  all  the   preconditions  for
execution.  As a result,  we completely  avoid concurrent
execution in the kernel.
