Author: avg Date: Sun Nov 4 13:46:28 2012 New Revision: 242565 URL: http://svn.freebsd.org/changeset/base/242565 Log: cpuctl_do_cpuid: explicitly use ecx=0 for cpuid call ... instead of whatever random value may happen to be in the register. ecx is important to some cpuid leaves. To do: extend cpuctl interface to provide for ecx value parameter.
