I thought an OS kernel was supposed to synchronise hardware counters on multiple CPUs when it was loading??
In regard to %tick being privileged register: yes and no. There is flag in that register the kernel can set, to allow user processes access to it. Earlier versions of Solaris made it privileged, but the later version allow user processes to read it.
