T42 CPU scaling limited

I have a IBM T42 Laptop with got acpi running.
I can control the speed of the CPU stragely only
1.80 GHz
1.60 GHz
1.40 GHz
I'd like to be able to trottle it down to 600MHz, thats also what's the value of /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq : 600000
An other try would be cpudynd but that stops with:
cpudynd version 1.0.1 Copyright: Ricardo Galli <[email protected]>
cpudynd: CPU frequency control disabled
Error: Nothing to do, exiting
I've read alot in this forum and can't find any advice here or elsewhere. Hopefully somebody knows.
Thanks

powernowd is a daemon (just like cpudyn) (it is in the aur) I did not mean the module
(it might however be a module as well, but it is not what I meant)

[Solved] How to remove default "performance" CPU-scaling governor.

I was goin' trough the cpu scaling wiki and i was able to add the ondemand
cpu scaling governor and the appropriate powerdriver with modprobe command.
Then the cpu speed was lowered as it should so i've added these two to the modules section in rc.conf as well, to start at boot.
After reboot cpufreq-info's output says that both governor is loaded, BUT it doesn't switch to ondemand mode.
1. How can I remove the performance mode?
2. Or is there a possibility to setup it somehow that it switches to ondemand only if i switch to battery mode?
3. Other problem was for me that
find /sys/devices/ -name ondemand
doesn't give back anything, so i cannot lower ondemands governor scaling limit. Where should be these settings?
Now cpufreq-info output:
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to [email protected], please.
analyzing CPU 0:
driver: powernow-k8
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 1000 ns.
hardware limits: 750 MHz - 1.50 GHz
available frequency steps: 1.50 GHz, 1.20 GHz, 750 MHz
available cpufreq governors: ondemand, performance
current policy: frequency should be within 750 MHz and 1.50 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1.50 GHz.

Configuring CPU scaling is a 3-part process:
1. Load appropriate CPU frequency driver

You stopped after the second part.
Ye, you were right. After i didn't found that folder i was looking for i didn't continue on it.
Turns out, if u use:
echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
It makes that folder, and u can access all those treshold variables.
But when just running first:
modprobe cpufreq_ondemand
the folder for ondemand won't be created. Im sure this is logical, i'm just new to the whole logic of this.
After modifying tresholds, i've installed laptop-mode, and I need to say, it really k*cks *ss. You can set everythin u want, and it runs along fine in a daemon, using for example: acpid for checking battery state, hdparm for setting power/spinning of hard disks...
I just leave another wiki link here if someone gets here...

There's still a not-releated question here, how come i cannot edit as a superuser directly these file under /sys/devices/system/cpu ? I know that these meant to be edited by the system, but still i tought if i'm root, i modify what i want...
( I know that I can assign parameters to these files with edit -n <number> > <filename> )

[SOLVED] CPU scaling doesn't work with the new kernel

I just updated my kernel to 2.6.16.1-7, but now my CPU scaling doesn't work anymore.

and the last line of dmesg:
speedstep_centrino: Unknown symbol acpi_processor_preregister_performance
Any ideas? Looks like this is an error in the speedstep_centrino module.. bit. As far as I know I hadn't this error with the -6 kernel package..

did you anything else except update your kernel version? because the problem isn't gone away here

MSI Wind cpu scaling & Fn key problem

I'm running Arch Linux with KDEMod KDE 4.2.2 and almost everything is working great.
CPU scaling is kind of working. At least now it says cpu scaling is working in power devil, but my only option is "performance". How do you I get it to let me actually scale down the cpu?
When I push Fn+F10 to enable eco mode or whatever it's called, nothing happens. If I have it plugged it the power button goes orange but when I check /proc/cpuinfo or hardinfo it says it's still running at 1.6 Ghz.

flammenwurfer wrote:CPU scaling is kind of working. At least now it says cpu scaling is working in power devil, but my only option is "performance". How do you I get it to let me actually scale down the cpu?
Make sure you have 'cpufreq_ondemand' kernel module loaded. You can find out about the scaling capabilities by looking at the contents of the /sys/devices/system/cpu/cpu0/cpufreq directory.
EDIT: or cpufreq_userspace or whatever you want to use.

[SOLVED]Laptop-mode-tools no cpu scaling

Hi!
After I installed laptop-mode-tools, I can't have my cpu freq scaling as I always did.
Well, I'll explain better: without laptop-mode-tools I used to set my cpu freq via /etc/rc.local, and everything was fine.
But now I need laptop-mode-tools and I have to say, everything works very well...But here comes the sun, uhm no, here comes the problem: when i plug in and out my ac cable, my frequency will stay at its lowest. The same thing happens after suspend... I can't understand...
I tried with acpid, obviously, and for example, when i plug in ac power, lcd brightness changes as expected from my config files, but cpufreq will stay just as I said.
So, here is my cpufreq-info now:
limiti hardware: 1000 MHz - 1.67 GHz
frequenze disponibili: 1.67 GHz, 1.33 GHz, 1000 MHz

in questo intervallo.

Ok, after i removed laptop-mode-tools and managed to have my cpu freq scaling,lcd brightness and eeepc she through rc.local and acpid events , i found that the real problem is located in ondemand governor: after suspend it stays at lowest freq possible.
If i change then my governor, with for example performance, it works, but if i change again to ondemand, it stays to its lowest...any idea?
EDIT: tried with granola and userspace governor, but nothing changes... tried on my other laptop with kernel 3.1.5-ARCH, and there everything it's ok, but i noticed i haven't acpi and acpid installed there...so may be the problem is related to them? (i use the same cpufreq driver in these laptops)
I'll try to kick out acpi and acpid and i'll make you know what happens.

Dual-layer 1,67 CPU scaling working? Technical experts welcome.

Hi,
I have done a pretty simple test using an application called "Reaktor". This is a music application which uses quite a lot of CPU.
On my new Alubook Dual Layer 1.67 GHz one of the instruments doesn't even play. The application CPU meter shows "over" , indicating a CPU overload.
On the previous generation 1.67 (non-DL) this instrument registers 70% CPU use. With the energy saver processor settings on "automatic" or "highest", the instrument still plays.
The only reason I can think of for this is the change from user managable processor settings (energy saver) to dynamic processor frequency scaling.
My question is this:
Is it possible that the new powerbook can make a mistake in recognizing when to scale the CPU to 1,67 GHz? If so, would this be an issue with the application (programming) not supporting this new technology or more a Powerbook architecture issue? Has anybody else run similar benchmarks?
I found this in another post:
The DL Powerbooks support both divide-by-two mode, AND, for the first time, divide-by-four mode. That is, the processor will set itself to 1.67GHz, 833MHz and 417MHz as needed for the particular task at hand. There is no user control over this switching; it is automated. Previous Powerbooks with 7447 processors have simply supported divide-by-two, e.g. 1.5GHz or 750MHz, with the user having the option to choose 'highest', 'automatic', or 'reduced'. The source for this information is the developer notes on the Apple Developer Connection website.
Having read this, I would assume that in the divide-by-four mode, the CPU is being run at 1.25 Mhz, but should be run at 1.67.
Any other observations / explanations would be appreciated.
Thanks,
Dan

CPU scaling on dual-layer powerbook

I've been recently looking into buying a powerbook and wondered if owners of the new dual layer PB could fill me in on its new power management scheme.
I understand Apple removed user control on CPU frequency scaling in their latest model. I would like to know if the CPU still reduces its frequency when plugged into AC power. I plan to leave the computer plugged in most of the time and it would be nice if it would still clock down to reduce heat and noise.
Also, what control do you still have over power management, can you control the video hardware's power saving?

The DL Powerbooks support both divide-by-two mode, AND, for the first time, divide-by-four mode. That is, the processor will set itself to 1.67GHz, 833MHz and 417MHz as needed for the particular task at hand. There is no user control over this switching; it is automated. Previous Powerbooks with 7447 processors have simply supported divide-by-two, e.g. 1.5GHz or 750MHz, with the user having the option to choose 'highest', 'automatic', or 'reduced'. The source for this information is the developer notes on the Apple Developer Connection website.
Interestingly, I had understood only the 7448 processor from Freescale was supposed to be able to support divide-by-four, and this was the processor that many speculated would be in this revision of Powerbook -- Freescale's first 90 nanometer G4 chip. However, it was not to be and this computer once again has a 7447 G4. I don't know how Apple has implemented it on this one -- perhaps the new ASIC controller chip that was allegedly causing trouble in testing.

No SpeedStep / CPU scaling in XP on new Alu Macbook

Installed XP Home SP2 via Bootcamp on my Late 2008 Macbook (2.0 ghz)
Was surprised to see the battery life go down by half under XP compared to Leopard
A quick check revealed that the CPU is running at full throttle (1.99 ghz even with 0% CPU utilization)
Why should this be the case.
I have the power options set to max battery and the CPU should be scaling itself down to lower clocks when not loaded
Can someone else with a late 08 MB also please check this and let me know

Hi Hatter, further to our other thread, the fundamental problem here is that Apple hardware uses EFI, not BIOS. There are many Windows apps for controlling CPU and GPU fan speeds, but they all rely on genuine BIOS hooks to control the physical hardware. Boot Camp provides a pseudo BIOS layer (over EFI) to allow install of Windows, but it does not go the extent of supporting CPU fan control, so Windows users are dependent on waiting for Apple to provide CPU fan control functionality in Boot Camp.
With regard to the NVidia 9400M GPU in particular, this is the only GPU/chipset range that NVidia does not provide consumer support for in their recent public driver release. Since Apple is the OEM that designed the implementation of 9400M on the Apple notebooks, only Apple can create drivers for them. So again, Windows users are dependent on waiting for Apple to provide GPU fan control funcionality in their Windows graphics driver under Boot Camp.

Build Table Within CPU Cycle Limits ::

I have a table that looks like this:
:Example Table:
customer_trail
database_update_date cust_activity cust_name
02/11/08 09:00 01/11/08 09:34 Bob
02/11/08 09:00 23/10/08 09:34 James
02/12/08 09:00 05/11/08 09:34 John
02/12/08 09:00 12/12/08 09:34 Mike
: Definitions:
The database_update_date is the primary key and is the date when everything gets loaded into the database.
The cust_activitity is when the customer came in and requested some work done.
The cust_name is the customers name.
:SQL:
SELECT TO_CHAR(cust.cust_activity ,'DD/MM/YY') AS Date_Raised,
TO_CHAR(cust.cust_activity,'HH24')||':00' AS 24HR_TIME,
cust.*
FROM customer_trail cust
WHERE database_update_date BETWEEN '01-nov-2008' AND '02-nov-2008'
AND cust_activity BETWEEN '01-nov-2008' AND '01-dec-2008'
AND cust_name IN ( 'Bob', 'Mike', 'Pete')
:PROBLEM:
My problem is this, due to the fact that the table is so large and we have so many customers. My query times out if I search for a months worth of data using the database_update_date attribute, so I am having to search 1 day at a time to build up a months worth of data in my new table called output. However this is a manual process of me changing the values within database_update_date and saving it to the output table.
Also there is no way to optimise my query and the table can not be changed easily.
So what I need to do is get it to update the database_update_date daily from the 01-nov-2008 to the 01-dec-2008 and store everything that matches the other two conditions without exceeding my CPU Cycle limit.
Any ideas?

Davey,
The design of the table has to be such that it supports its use the best way. If the query you showed is the query that it needs to be optimized for, you'll want to look into partitioning and indexing this table. Range partitioning on cust_activity and a local index on (cust_name,database_update_date) maybe?
But there is really too little information here. Is this the main query and a typical one? How many rows are you typically retrieving here? How large is large? Can you show an explain plan and a tkprof file snippet?

Helix CPU frequency limited to 0,3 GHz after replacement of mainboard (Win 8.1)

Hi,
I have a weird problem: The mainboard of my Helix was replaced by Lenovo because it was defective. Now, the CPU frequency does not exceed 0,3 GHz (16% CPU utilization). The laptop is unusable because it is soooo slow. See the screenshot below.
The technician who exchanged it says: "hardware is ok, please "Format C:", it's a software problem " I don't want to do that.
The Lenovo support says: "We don't know."
I tried to run and reinstall Lenovo Solution Center to run a hardware scan, but the service doesn't work.
Who can help? Is this a software or hardware problem?
Christian

Do battery levels have any influence on this?
Does it change anything if you unplug the charger?
Did you hard reset both the tablet and the base using a pin?
Do you have the latest BIOS?
If so is "Cool Mode" turned off and power settings set to "max performance"?
Do you have the latest Lenovo Power Management (PM) driver installed?
Did you try switching around between power plans (in Windows - RMB on the battery icon)?

865PE CPU Voltage Limitation? (also posted an P4 based board 2 days ago)

Hello everybody,
I already posted that at P4 based board, but I thought posting it here as well, as you're more likely to play with such settings and values.
I have a P4 2.4C oc @ 3.3GHz with [email protected] The only thing keeping me "down" here is that if I set Vcore to 1.9Volts or higher my system won't boot at all. The screen stays black, and the CPU surely doesn't work as it stays cold. Loading BIOS default values is a pain in the a... as insert won't work (for some of you this is delete for your mobos) and usually the only way is to turn the PSU off while the mobo tries to boot. Any clue why this happens???
-Is it a defect of the board?
-Is it a protection limit of the board? Then why it allows much higher values?
-Is it a defect of the CPU?
-A protection limit of the CPU?
-A PSU problem? I own a cheap (for it's watts) 550PSU.
Please help! I want more speed!
Thanx for your time reading this!

Your temperatures are too high, which leads me to think we and other pople have a sensor problem or something similar.
I think it could be a combination of things as I have just tried a few tests with and without my case cover on and the results are only 1C lower without the case cover on.
Currently I am getting CPU 59C Idle NB 39C Idle and only 3C higher under load. I think that if the ambient air temp is very high (like it has been in London for the past week) it causes the sensor to overload or go haywire as it cannot cope. I am pretty sure that the Intel thermal protection is very good (if it does not work they have to replace you CPU if it is under the 3 year warranty) so they must be pretty confident of its abilities.
The other thing to consider is that I also de-installed PC Alert4 and went back to PC-Alert3 which seems to be more accurate when comparing between the 2 within the space of a few minutes as PCA3 showed 10C less CPU & 13C less NB.
Probably a combination of PCA4 and poor sensor methinks.
I doubt if extra case fans will make a huge difference but will still another 1 in just in case as they are cheap.

[solved] GNOME cpu frequency scaling monitor applet doesn't work

Hello,
i have installed everything successfully (i come from fedora), but now i have a problem
I want to add the cpu frequency scaling monitor applet to the panel, but i can't see it. When i rightclick on this place, the submenu with settings and so on is displayed, and i can choose the other cpu1 instead of cpu0, then the applet appears. But the applet shows 0 Mhz and i can't choose a frequency or something.
I start GNOME with xinit and have added exec ck-launch-session gnome-session to ~/.xinitrc, because shutdown wasn't displayed at the beginning and automouting permission problems.
What's the problem?

the problem is that the modules are not loaded automatically for cpu scaling and you have to explicity add them into rc.conf, MODULES array.
MODULES=(...acpi-cpufreq cpufreq_ondemand...)

Azure Cloud Service Scaling - do I have to configure a Load Balancer?

I'm a little bit confused by how scaling in Azure works. I'm using a Cloud Service and have 2 web roles running a PHP application. I can RDP on both machines and both applications run great on each machine. Also I don't have any problems calling the staging
URL.
But I can't figure out if I configure scaling so that 2 machines run always, if I have to configure a load balancer somehow. Or is this already done for me?
In Azure VM's I had to create a load-balanced set endpoint for an endpoint, but what about cloud services?
And how is this done in the XML configuration file for my service? What if I don't do it?

Hi,
Scaling is affected by core usage. Larger role instances or Virtual Machines use more cores. You can only scale an application within the limit of cores for your subscription. For example, if your subscription has a limit of twenty cores
and you run an application with two medium sized Virtual Machines (a total of four cores), you can only scale up other cloud service deployments in your subscription by sixteen cores. All Virtual Machines in an availability set that are used in scaling an
application must be the same size.
Windows Azure supports load balance for cloud services and standard websites, we just need to set instance count to more than 1 to enable load balance. For virtual machines, it needs to set up manually.
Please refer this link for Load Balance a Virtual Machine:
http://www.windowsazure.com/en-us/manage/windows/common-tasks/how-to-load-balance-virtual-machines/
for more information.
Auto scale lets you set scaling limits and scheduling goals to ensure you are always getting optimal performance
Please refer this link for Scaling on Cloud Services:
