Hi, | By Rui Paulo <rpaulo@fnop.net> | [ 2007-12-24 14:43 +0200 ] > Isn't it better to teach est(4) to ignore values that differ in, say, > +/- 5Mhz ? I agree my patch isn't ideal. I was thinking about it today and it might be useful to implement something that ignores frequencies whose power ratings don't differ by more than X mW. In my case, both 2201 and 2200 are rated to draw 35000 mW. The question is, in these cases which one of the two should be ignored? Can't ignore both... Sorry Andrey, I missed your patch. Was a bit overly excited when I saw someone else finally experiencing the same problem as me after receiving zero response a month ago when I posted about it. :) Something I asked in my post a month ago was where does dev.cpu.X.freq_levels get its data? I was thinking it might be something that can be addressed with a patched ACPI DSDT? Regards, Aragon
