Summary: cpufreq not working on HP tx1000
Product: Power Management
Version: 2.5
KernelVersion: 2.6.24
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: cpufreq
AssignedTo: cpufreq@www.linux.org.uk
ReportedBy: rap@ramonantonio.net
Latest working kernel version: Unknown
Earliest failing kernel version: 2.6.24
Distribution: Debian Unstable
Hardware Environment: HP tx1230es
Software Environment: -
Problem Description: I can change cpufreq governor but never changes frequency.
Fan works most of the time. Tried 2.6.24 and 2.6.24-git12 (git12 includes a
patch for this model).
Steps to reproduce:
neonlight:~# cpufreq-set -g powersave
neonlight:~# cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: powernow-k8
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 800 MHz - 1.90 GHz
available frequency steps: 1.90 GHz, 1.80 GHz, 1.60 GHz, 800 MHz
available cpufreq governors: ondemand, powersave, userspace,
conservative, performance
current policy: frequency should be within 1.90 GHz and 1.90 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 1.90 GHz (asserted by call to hardware).
analyzing CPU 1:
driver: powernow-k8
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 800 MHz - 1.90 GHz
available frequency steps: 1.90 GHz, 1.80 GHz, 1.60 GHz, 800 MHz
available cpufreq governors: ondemand, powersave, userspace,
conservative, performance
current policy: frequency should be within 1.90 GHz and 1.90 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 1.90 GHz (asserted by call to hardware).

Here is some cpufreq debug info. Tried to change governor with
cpufreq.debug=7 as kernel attribute. Continues to fail. Same result
with all governors compiled as modules or not.
