[Bug 216205] New: GNOME: The CPU frequency scaler seems to work in an opposite way
https://bugzilla.novell.com/show_bug.cgi?id=216205 Summary: GNOME: The CPU frequency scaler seems to work in an opposite way Product: openSUSE 10.2 Version: Beta 1 Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Mobile Devices AssignedTo: behlert@novell.com ReportedBy: mboman@novell.com QAContact: qa@suse.de I've got openSUSE 10.2 Beta1 installed on an IBM Thinkpad T43P. I've added the CPU frequency scaling monitor applet to my panel. Every time the laptop is "idle" the CPU is running at full speed (100%). When performing heavy operations, such as compiling gargnome etc, it goes down to 35%. I've configured the system for maximum performance. Let me know what I can collect for you to help troubleshoot this one. -- 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.

Can you add CPUFREQ_ENABLED="no" in /etc/sysconfig/powersave/cpufreq and try some things manually, pls. This doesn't work. I had to manually comment out the loading of speedstep-centrino etc in /etc/init.d/acpid (lines 180 and 181)
First, is this phenomenon always happening or does it only happen after some time? It happens every time
Try to load the cpufreq driver by hand (modprobe speedstep‑centrino, if this does not work it should be modprobe acpi). After modprobe, CPU freq. is on 100%
Load governors by hand: modprobe userspace;modprobe ondemand;modprobe performance mblxws01:/home/mboman # modprobe userspace;modprobe ondemand;modprobe performance FATAL: Module userspace not found. FATAL: Module ondemand not found. FATAL: Module performance not found.
cd /sys/devices/system/cpu/cpu0/cpufreq echo ondemand >scaling_governor (does cpu get switched up and down on CPU load?) Yes, CPU is switched up and down
Let it stay down and try: echo performance >scaling_governor Is the machine on lowest freq now? If yes, we hit the bug. No, CPU freq goes to 100% and stays there
Does echo userspace >scaling_govornor;echo 2266000 >scaling_setspeed switch up to highest freq now? CPU is already on max freq. echo'ing 800000 will set it to min freq. Then I can switch it back to max with echo'ing 2266000
If yes, do echo ondemand >scaling_governor (does cpu get switched up and down?) Setting it to ondemand makes it switch up and down
It seems that if I make one manual change to the governor, it will behave as it should. -- 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.

Can you get the output of #cat /proc/acpi/thermal_zone/*/* before and after you have this state. Output of #cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq will also help. We have seen similar issue earlier. What happens is that the CPU max frequency gets reduced due to thermal condition and even when you have any governor ondemand/performance/ they cannot use higher freq until temparature event goes away. -- 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.

When I first turned on the laptop, it seemed to work fine. So I stressed it a bit and after a couple of minutes, it refused to go to highest frequency for more than a couple of seconds.

Let _PPC always return zero unconditionally Can you pls try: cp DSDT.aml /etc/DSDT.aml Modify ACPI_DSDT="" to ACPI_DSDT="/etc/DSDT.aml" in /etc/sysconfig/kernel invoke: mkinitrd reboot and try whether it works now (also check in dmesg for a string like: DSDT replace by OS (you should be able to grep that easily by something like "dmesg | grep -i initrd", or "dmesg | grep -i dsdt". Is the machine always at lowest speed as soon as powersaved or hal started and the cpufreq driver got loaded? (Can't see the other comments right now, maybe I already asked that..) After testing you should better revert the change in: /etc/sysconfig/kernel and invoke mkinitrd again. What is being done here is a BIOS table (one that was included in acpidump and which I modified) is replaced by the kernel (only in ram, so no problem to revert the change). If this works we can be sure that something is wrong with _PPC (the function the kernel invokes to check whether BIOS has limited CPU frequencies). I only know about thermal limits and this one, it theoratically could be something else, but due to the dmesg debug output you sent, chances are quite high that it's that. -- 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.

Are there any negative impacts using this one until we have a final solution? Not really, as long as you don't alter HW (e.g. plug in more memory) or update BIOS. If you update BIOS and it still does not work, can you attach acpidump again,

I'd say something is broken and we should find out what it is, at least for SLE11 and mainline. 10.2 is out now and backports are risky, we cannot do much about this one and there at least exists a workaround (hopefully also for the ASUS model). Sun: Can you also do checks described in comment #29, pls. This looks like a problem deep in ACPI interpreter code and could be hard to find. As there are more critical bugs where no workaround exists, I like to keep this one for later.

If missing local apic timer in C2 is the problem, workaround should be simple. Enable timer_broadcast on C2 for these systems. Thanks. I first thought it's much earlier when APIC is set up. If it's that: "when timer to wake up C2 is chosen, the kernel thinks it's an SMP machine, because this one has two APICs (one disabled) and takes the wrong method for waking up from sleeping states", I should be able to fix this... I have access to the machine on Mo/Tue again and hopefully can come up with something then.
We use smp kernels also on UP machines since 10.2 (without CONFIG_SMP all is fine).
But, are these Core 2 based laptops? Then C2 should not have this local APIC issue No, these are Pentium M.
