Hhm. The kernel menuconfig says : This driver provides a P state for Intel core processors The driver implements an internal governor and will become the scaling driver and governor for Sandy bridge processors. What shall a company like IBM with a lot of notebook installation running BOINC in the back ground process (World Community Grid) do - what's the consequence for those installations if they will have that a processor ? In the past (few years ago and related to the ondemand governor IIRC) there were already a longer discussion about the "nice -n 19" topic and the result was to support it. /me Cc:'ing boinc devs, the topic might be interesting for them too. >> Because the CPU will be running mostly at high(er) frequency - which >> always results in a high temperature and short battery time. >> > > It would be better IMHO if the client software limited the resources > it uses when the system is not on wall power but that is a seperate > discussion :-) > > --Dirk > > -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
