I don't understand: you want the thermal zones to not throttle your cpu to 800 Mhz and/or the fan to start sooner? > So, my original problem would be solved > by: > a) Direct control of the fan, to be able to put it on full for example > through userspace control, That's always a bad idea, especially if userspace dies on you. > b) Changing the active cooling thermal zones, so that the fan speeds > up earlier, or Ok, I see, here's what you want. > c) Changing the passive cooling (CPU throttling) thermal zones, so > that it doesn't prevent fan from speeding up in the first place. > > At the moment, I don't see any way to change the thermal zones through > existing interfaces for this laptop, and I don't see any potential > thermal zone controls, or manual fan control option in the Embedded > Controller registry. I'll let Peter have a look at the patch too. @Peter, it is at: http://lkml.org/lkml/2012/9/25/92 Btw, the commit message starts with "x86:... " and it should be "acerhdf:.. " Peter, please change that when handling the patch further. Also, you've added yourself to the copyright - this means that you're pretty much going to get all future email about acerhdf.
