Would be great. Is this possible? Just kidding. I don't like ondemand. It isn't doing anything good for C3. There is no significant difference between halt/ACPI C2/ACPI C3 on 533Mhz and 999MHz. Difference is when processor is *running*. With ondemand it is running very short on 533MHz. When I was testing ondemand my CPU was running max f most the time. With conservative it is running min f most the time. CPU is much cooler and it is running fanless for most the time. Best part is that conservative is doing more transitions when system is busy because it needs to do all the steps (66MHz step for me) from min (533) to max (999). Ondemand is doing only one transition - from min to max. > From: Rafal Bilski > Date: Sun, 22 Apr 2007 10:26:04 +0000 (+0200) > Subject: [CPUFREQ] Longhaul - Revert Longhaul ver. 2 > X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fdavej%2Fcpufreq.git;a=commitdiff_plain;h=07844252ffd81ec192a62014bada1016c9703765 > > [CPUFREQ] Longhaul - Revert Longhaul ver. 2 > No. It is new thing in 2.6.21 which will stop Longhaul from changing frequencies. As usual tested by email. Works for one, not works for others. Without this patch older C3 will not change frequency. Longhaul will be disabled for good. But both processors which we are talking about are "Powersaver". New. ---------------------------------------------------------------------- Wicie, rozumicie....
