Custom 64 bit ubuntu kernel 3.0.4 optimized for i3, i5 and i7

Kernel Configuration 3.0.4

1. Followed Ubuntu way of building kernel (to know more follow this link)
2. Used EL6 config as base (copied EL6 config instead of cp debian.master/config/amd64/config.flavour.generic debian.master/config/amd64/config.flavour.i7)
3. Selected processor as CORE2 
4. Used GCC 4.6 (to use the new arch corei7 which is for i3, i5 and i7 intel processors)
5. Edited main Makefile to append -march=corei7 -mtune=corei7
6. Enabled transparent hugepages support
7. Enabled all cpufrequency scaling drivers like ubuntu

How to install


Extract the kernel zip file, and enter into the extracted folder in terminal (using open in terminal in nautilus)

sudo dpkg -i linux-headers-3.0.4-030004_3.0.4-030004.201108301138_all.deb linux-headers-3.0.4-030004-i7_3.0.4-030004.201108301138_amd64.deb linux-image-3.0.4-030004-i7_3.0.4-030004.201108301138_amd64.deb

Changes done in my system

Added pci=nocrs to kernel in /etc/grub.d/10_linux to avoid pci address space conflict warning

GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT pci=nocrs"

Ran update-grub2 to regenerate grub entries

Added acpi_cpufreq in /etc/modules to enable cpufrequncy scaling (by default not adding acpi_cpufreq module in /etc/modules ran my processor in full speed and I was happy to the overclock frequency working!!, or in other words if you overclock dont add acpi_cpufreq in /etc/modules)

Custom kernel 2.6.38.3 ubuntu amd64 packages optimized for i3, i5 and i7 processors

Kernel 2.6.38.3 amd64 ubuntu packages optimized for i3/i5 and i7  built by me and uploaded to dropbox for anyone who would like to test. The builds are done using latest GCC 4.6 installed from ppa ubuntu-toolchain-r/test/ubuntu. 

Latest GCC 4.6 added new targets for i3/i5 and i7 processors which is corei7. The builds utilize this new target of gcc!
