Author: imp Date: Fri Apr 26 05:42:35 2013 New Revision: 249919 URL: http://svnweb.freebsd.org/changeset/base/249919 Log: Octeon 2 (6xxx) and newer CPUs don't use the clock CPU speed for its I/O clock. Thankfully, the simple executive provies a way to querry the proper clock that works on all models. Move to asking for the SCLK via this interface. This gets the serial console working after we start init and open the console and set the divisor (which turned the output from good to bad). I can login on the console now.
