Author: kib Date: Fri Jun 3 18:23:45 2016 New Revision: 301279 URL: https://svnweb.freebsd.org/changeset/base/301279 Log: Trim some spaces to record correct commit message for the r301278. Reduce number of iterations used for calibrating ICR read loop. The new number of iteration still gives the same ICR latency as before, tested on Intel SandyBridge and Haswell machines, and on AMD. But it significantly reduces the unneeded pause on boot in some VMs, from ~10 secs to less then 1 sec. It was reported to occur in bhyve on AMD host.
