It's not enabled by default in Solaris. You have to enable it by editing power.conf(4) and adding the following entries:
cpupm enable cpu-threshold 15s And then in order to inform the kernel of the new policy, you must run pmconfig(1M). Alternatively, you could use the /usr/dt/bin/dtpower GUI. As far as the comparison against Linux though, it makes no sense to enable CPU power management on Solaris if it wasn't enabled on Linux. Mark
