Hi, I have a compaq nx9010 laptop, running on kernel 2.4.9-gentoo-r13, with ACPI enabled and speedstep for frequency scaling.
Which variant of speedstep?
...and this is also what speedstep does - it switches between these two frequencies, 96% and 100% speed. Isn't this absolutely nonsense? Only 4% speed difference !?
It most likely is nonsense...
On the other hand my dsdt contains two entries in the _PSS section, one for 3059MHz (100%) and one for 1596MHz (~50%) - but those two frequencies appear nowhere in /proc or /sys/devices/... !?
What does using the acpi-cpufreq driver lead to?
Is speedstep independend from ACPI ?
It depends on the driver and sometimes on driver settings whether it is independend from ACPI or not.
