My experiments with Linux: Custom kernel 2.6.39.3 ubuntu i3 i5 i7 optimized

Friday, July 15, 2011

Custom kernel 2.6.39.3 ubuntu amd64 packages optimized for i3, i5 and i7

Requirements

This package is created in Ubuntu 11.04 and should install fine in all versions of Ubuntu Linux 11.04 (as well 10.10) and Linux Mint 11 (as well Mint 10) (should as well in debian squeeze but not sure about dkms)

The build is for 64bit i3, i5 and i7 processors

The following are the configuration settings

Processor is selected as CORE2
Makefile and Makefile_32 modified to reflect march settings and mtune settings to corei7
Configuration of oneiric kernel is taken as base, http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.39.3-oneiric/
Kernel Timer Frequency is 100 HZ as oneiric kernel config defaulted to this frequency

How to install

To install

sudo dpkg -i linux-image-2.6.39.3-corei7swiftr_14.00_amd64.deb linux-headers-2.6.39.3-corei7swiftr_14.00_amd64.deb

followed by (these steps update-initramfs and update-grub are not required for mint10 or maverick, these were required when using Ubuntu Lucid)

sudo update-initramfs -c -k 2.6.39.3-corei7swiftr

and final step of

sudo update-grub

before rebooting and reboot into the newly installed kernel from grub
