[Bug 258425] New: Powersave/cpufreq not initialised properly on boot - subsequent ondemand governor issues
https://bugzilla.novell.com/show_bug.cgi?id=258425 Summary: Powersave/cpufreq not initialised properly on boot - subsequent ondemand governor issues Product: openSUSE 10.2 Version: Final Platform: i586 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: karl-heinz_tm@hotmail.de QAContact: qa@suse.de Machine is Sony Z600TEK - somewhat old laptop (P3-700 Coppermine) Initialisation of frequency scaling fails during boot - system message claims that frequency scaling wasn't supported. Once machine is up, it's possible to enable frequency scaling by executing modprobe speedstep-lib relaxed_check=1 modprobe speedstep-smi smi_cmd=0x82 smi_port=0xb2 rchal restart However, enabling the ondemand governor still produces errors such as "liblazy (liblazy_dbus_send_method_call:71): Received error reply: Initialization of ondemand interface failed" and kernel messages such as "ondemand governor failed to load due to too long transition latency". Nevertheless, the ondemand governor does get activated, i.e. dynamic frequency changes do occur. Note, there were no such errors under opensuse 10.1 frequency scaling worked flawlessly there. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I suspect that it's the userspace governor which does the dynamic scaling. Can you please attach the output of grep -r . /sys/devices/system/cpu/cpu?/cpufreq/ Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

The only issue is that you need to define additional parameters for speedstep-smi. Are you sure you need the relaxed_check=1 for speedstep-lib? You can place a file to /etc/modprobe.d/ for the driver to get automatically loaded on boot. Just have a look at /etc/modprobe.d/ibm_acpi as example. Sorry, but I have to close this bug as WONTFIX. We cannot know which module options to use for every old CPU, sorry. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
