Author: ian Date: Tue Oct 20 15:15:30 2015 New Revision: 289631 URL: https://svnweb.freebsd.org/changeset/base/289631 Log: Uncomment some rather important code that was commented out for benchmarking. Normally this routine is supposed to loop until the PIC returns a "no more interrupts pending" indication. I had commented that out to do just one interrupt per invokation to do some timing tests.
