Glad I could at least amuse you. By the way, spell check didn't catch "elses"? Yes, I've already filed: 6636222 "NOTICE: cpudrv_pm_set_topspeed: instance 0: has new max power of 2000 MHz" needs to go > > BTW, if you, or anyone else writes any code that will reduce the speed of a > CPU and want it tested on a Intel Core 2 Duo T7200 2.0 GHz, which (according > to the sticker on the front of my laptop) "supports Intel SpeedStep > Technology", let me know. > > kstat -m cpu_info -s supported_frequencies_Hz > > says it supports 1000, 1333, 1667 and 2000 Watts (sorry, MHz). Actually, I really hope it was reported in Hz not MHz. ;-) Try adding the following to your /etc/power.conf file: cpupm enable cpu-threshold 15s I believe these keywords are in the the power.conf(4) man page shipping with snv_70b. Then execute /usr/pmconfig. I think you'll find that code has already been written to reduce the speed of your CPU. And we're working on improving it and Solaris power management in general. We've got a bit of catching up to do. Mark _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
