[EN][T&T] Intel ss4200: 3.2 kernel\CPU governor\LEDs\more

nox86 · 10. Dezember 2012

There are notes from my OMV installation (and yes, you can recompile p4-clockmod.ko, but patch is faster)
0. In OMV 0.4 serial console works by default!
1. update kernel

Code

echo "deb http://backports.debian.org/debian-backports squeeze-backports main" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get -t squeeze-backports install linux-image-3.2.0-0.bpo.4-amd64 firmware-linux-free

2.patch p4_clockmod.ko (81 96 98 00 > 80 96 98 00) and install cpu governor (ask google for the magic number if you care)

Code

sudo apt-get install cpufrequtils sysfsutils vim-common
cp /lib/modules/3.2.0-0.bpo.4-amd64/kernel/drivers/cpufreq/p4-clockmod.ko /tmp
xxd -p < /tmp/p4-clockmod.ko | sed 's/81969800/80969800/' | xxd -r -p > /tmp/p4-clockmod.ko.new
sudo mv /tmp/p4-clockmod.ko.new /lib/modules/3.2.0-0.bpo.4-amd64/kernel/drivers/cpufreq/p4-clockmod.ko


echo p4_clockmod | sudo tee -a /etc/modules
echo cpufreq_ondemand | sudo tee -a /etc/modules

Use this, or enable System>Power Management>Setting>Monitoring in WebUI

Code

echo "devices/system/cpu/cpu0/cpufreq/scaling_governor = ondemand" | sudo tee -a /etc/sysfs.conf

Reboot or use modprobe

cpufreq-info should output smth like this:

Code

current CPU frequency is 200 MHz.
  cpufreq stats: 200 MHz:31.49%, 400 MHz:0.00%, 600 MHz:0.00%, 800 MHz:0.00%, 1000 MHz:0.00%, 1.20 GHz:0.00%, 1.40 GHz:0.00%, 1.60 GHz:68.51%

3. install sensors

Code

echo dme1737 | sudo tee -a /etc/modules

check them

Code

ls /sys/bus/i2c/drivers/dme1737/0-002e/

You are welcome to add ss4200 specific tweaks here

k0gen · 11. Dezember 2012

Excelent! I'll try that tomorrow ...
Quick question: why are you using 64bit version? (knowing that our SS4200 can use max. 2GB of ram)

nox86 · 13. Dezember 2012

Zitat

ss4200@omv:~$ uname -r
3.2.0-0.bpo.4-amd64

Why not? Just download 64bit iso

Add mdad event handling script:

Code

chmod u+x  /usr/sbin/mdadm-event-handler.sh
echo "PROGRAM /usr/sbin/mdadm-event-handler.sh" | sudo tee -a/etc/mdadm/mdadm.conf
sed -i "s/\(DAEMON_OPTIONS *= *\).*/\1\"--syslog --program \/usr\/sbin\/mdadm-event-handler.sh\"/" /etc/default/mdadm
/etc/init.d/mdadm restart

*remember about dme1737 kernel module
or\and add cron job

Code

sudo mdadm --monitor --scan -1 --program /usr/sbin/mdadm-event-handler.sh

/usr/sbin/mdadm-event-handler.sh

Bash

#!/bin/bash
MDEVENT=$1 #The Event that occurred
#MDDEVICE=$2 #The md device that is affected
PHYSDEVICE=$3 #The physical disk that is affected


# $0 - sd[1-e]
function get_hdd_idx () {
	ls -l /dev/disk/by-path | sed -n "s/.*1f.2-scsi-\([0-3]\):0:.*sd$1/\1/p"
}

	exit

Can I follow this guide to update the kernel of my system ? I do not have Intel ss4200

What kind of system do you have? p4-clockmod is not suitable for all systems as i remember. Most work with acpi-cpufreq (intel) or powernow-k<number> (AMD).

Something to think of:
Why do you want to Upgrade, what is not working? Sure that the upgrade will fix your issue? Is it so urgent that you cant wait for the OMV release with wheezy?

hawaix · 17. Mai 2013

I just want to update the kernel I have a system with CPU i7 (Watch my signature) I am not happy with the performance and I want to try updating the kernel (maybe it's a driver problem), in my system everything works fine . If this guide is not good to update my system you know any guide? Thanks

knumsi · 18. Mai 2013

i think this part could do it (as root):

Code

echo "deb http://backports.debian.org/debian-backports squeeze-backports main" | sudo tee -a /etc/apt/sources.list
apt-get update
apt-get -t squeeze-backports install linux-image-3.2.0-0.bpo.4-amd64 firmware-linux-free

But dont ask me how to go back from there. I would not try it. Going back is not that easy P4 Clockmod is nothing for your i7. acpi-cpufreq should be already installed and running.

where do you think your performance is not satisfying? perhaps we can figure out if it is possible that the performance will increase when upgrading the kernel ... (mostly it does not ...)

hawaix · 18. Mai 2013

Ok thanks , I try first on my OMV for test

Zitat

where do you think your performance is not satisfying?

1) when the HD have a higher loading
2) I have 2 network cards PCIe in Balance-tlb the data transfer is sometimes slow

I want to investigate better

Installing the backports kernel does not uninstall the standard 2.6 kernel. You can still select it in the grub boot menu. Very safe to try and I use it on quite a few systems.

thanks for the explanation

Solution: added pata_legacy module...:-)

--------------------

Hey!

I installed OMV on my SS4200 following: http://forums.openmediavault.org/viewtopic.php?f=12&t=188. Afterwards I followed this thread and upgraded to the 3.2 Kernel, but the device fails to start.

Code

Gave up waiting for root device. Common problems:
...
ALERT! /dev/disk/by-uuid/... does not exists
Dropping to a shell!

The workaround from the first mentioned thread doesn´t work anymore:

Code

echo ata_piix >> /etc/initramfs-tools/modules
echo ide_generic >> /etc/initramfs-tools/modules
5.) After modifying the file you must update the system with the command:
update-initramfs -u

Jetzt mitmachen!
