Разгон процессора Nokia N900 (Страница 40 из 89)

125 и 200 что это за цифры и какую роль выпольняют?=)

SR, есть успехи с изменением частоты без постоянной смены ядра?

There is a new stable overclockable kernel in extras-testing (version 2.6.28-maemo19, not 18!!).
Installation is very simple: install the package kernel-flasher-maemo (section system in HAM), shutdown and cold boot. There's no need for reflashing etc.
It requires firmware PR1.1 or newer.

The default limit is at stable 600MHz. This is the same setting as the stock kernel and is safe.

This kernel makes it possible dynamically change the maximum frequency up to 1.2GHz (supported frequencies are 250,500,550,600,700,750,800,850,900,950,1000,1100, 1200MHz)
WARNING: Overclocking may damage your device and is at your own risk! It may void your warranty and destroy your data. You have been warned.
You can manually increase the limit until your device fries using, e.g. for 600MHz
Code:
sudo gainroot
echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
The last line shows which value was actually set.
This setting takes effect immediately and is cleared with the next reboot or overriden by
every phone call with the value 600MHz.
To permanently fix a limit you found to be stable edit the scaling_max_freq setting in /etc/pmconfig (e.g., using vi).
WARNING: Permanent overclocking is very dangerous!
Until we find a solution you need to set your desired frequency after every phone call again.

Apart from overclocking, this kernel has a lot of other features
(2.6.28.10, PR1.2 SDK patches etc) see http://talk.maemo.org/showthread.php?t=43420
It also retains the version info in Settings -> Product info (if it is still available).
If it works well for you, please vote at
http://maemo.org/packages/package_in....6.28-maemo19/

For deinstallation of this kernel run
Code:
sudo gainroot
apt-get install --reinstall kernel kernel-flasher
apt-get remove kernel-maemo kernel-modules-maemo
PS: 125MHz is deliberately not included, see http://talk.maemo.org/showpost.php?p... … tcount=141

Good luck!

Linux kernel updater for an enhanced Maemo 5 kernel 2.6.28.10

This package will flash the kernel image upon installation. If you want to revert to the stock Nokia kernel, run "apt-get install --reinstall kernel kernel-flasher" as root or use the flasher to flash the extracted zImage from the firmware image. For discussion and support please visit http://talk.maemo.org/showthread.php?t=43420

This custom kernel contains additional modules for IPv6, packet filtering, QoS, NAT, tunneling, kernel configuration, Wifi mesh networking, builtin ext3 for booting from other media, ext4, XFS, reiserfs, NTFS read support, ISO9660, UDF, CIFS, automounter, UNIONFS, device mapper and dm-loop, cryptography, cryptoloop, EFI partitions, UTF8 codepages, mouse+joystick input, PPP, serial support, USB/IP and generic USB device drivers, overclocking and kexec support.

Warning: Overclocking may damage your device and is at your own risk!

Known bugs: Touchscreen calibration (osso-applet-screencalibration) is incompatible with the enabled evdev modules. You need to use the stock Nokia kernel for calibration.

разогнал проц. по benik-ским способ, впринципе всем доволен, ничего не греется, глюков пока не замечал, единственный момент - в меню settings пропала версия моей прошивке, так же ее нет в проге healthcheck. у всех такая хрень или только у меня?
