Hi, Attached are the work I've done so far for my Summer of Code project. If you have a MacBook and are willing to spend some time build -current with these patches and testing, here's what you should know: 1) Grab the patch a http://fnop.net/~rpaulo/freebsd/macbook.diff 2) Apply it to today's -current 3) Build a kernel. Load three modules: backlight, msrtemp, cpufreq (est). The only one that shouldn't work out of the box on MacBook Pro's backlight. backlight controls the LCD backlight. You should have hw.backlight.{enable,value} after loading the module. Play with it to see if it works. I didn't test MacBook Core 2 Duo, but it should work. I have a feeling that it should be very easy to make it work for the MacBook Pro, but contact me if you need help. msrtemp displays the Cores temperature. There should be N new sysctls, one for each CPU. For example: $ sysctl dev.cpu.{0,1}.temperature dev.cpu.0.temperature: 53 dev.cpu.1.temperature: 53 est should detect, at least, the following values: dev.cpu.0.freq_levels: 2000/31000 1833/28016 1667/25033 1500/22050 1333/19066 1000/13100 Don't panic if you have more :) I disabled p4tcc and acpi_throttle on purpose. Have fun! -- Rui Paulo
