Author: davidxu Date: Fri Aug 17 02:26:31 2012 New Revision: 239347 URL: http://svn.freebsd.org/changeset/base/239347 Log: Implement syscall clock_getcpuclockid2, so we can get a clock id for process, thread or others we want to support. Use the syscall to implement POSIX API clock_getcpuclock and pthread_getcpuclockid.
