Hi all,
I have tried to use the "conservative" cpufreq governor
on my Athlon64 X2 (dual-core), Tyan K8S board. When I set up the
"ondemand" governor, it works as expected - under the load the
CPU frequency is raised to maximum, and when the load stops,
the frequency slowly returns back. When I switch to the
"conservative" governor, it just stays on the same frequency all
the time not depending whether there is a CPU load or not.
I have 2.6.15-rc6 kernel, Fedora Core 4 (native x86_64),
and I do not touch the default values in /sys/devices/system/cpu/*/cpufreq
except that setting a different governor. When the conservative governor
is on, I have the following settings:
./conservative/freq_step 5
./conservative/ignore_nice 0
./conservative/down_threshold 20
./conservative/up_threshold 80
./conservative/sampling_down_factor 5
./conservative/sampling_rate 124000000
./conservative/sampling_rate_min 62000000
./conservative/sampling_rate_max 1870457856
./scaling_cur_freq 1000000
./cpuinfo_cur_freq 1000000
./scaling_available_frequencies 2200000 2000000 1800000 1000000
./scaling_available_governors conservative ondemand performance
./scaling_driver powernow-k8
./scaling_governor conservative
./affected_cpus 0 1
./scaling_max_freq 2200000
./scaling_min_freq 1000000
./cpuinfo_max_freq 2200000
./cpuinfo_min_freq 1000000
Does anybody have working conservative governor? And with K8,
or dual-core K8?
Thanks,
-Yenya
