[SOLVED] Don't know how to apply Ubuntu patch on Vanilla kernel

Dezfor · 06-29-2011, 01:00 PM

I downloaded linux-source-2.6.38.deb, installed it. But I don't know hot to apply Ubuntu/Debian-specific patch to vanilla-kernel.
After installation of Deb in /usr/src/ I see:

Code:

$ ls -l /usr/src/
drwxr-xr-x 4 root root 4096 2011-06-27 01:20 linux-source-2.6.38
lrwxrwxrwx 1 root root   47 2011-06-27 01:20 linux-source-2.6.38.tar.bz2 -> linux-source-2.6.38/linux-source-2.6.38.tar.bz2

Code:

$ ls -l /usr/src/linux-source-2.6.38
drwxr-xr-x 10 root root     4096 2011-06-27 01:20 debian
drwxr-xr-x  8 root root     4096 2011-06-27 01:20 debian.master
-rw-r--r--  1 root root 75789876 2011-04-11 12:10 linux-source-2.6.38.tar.bz2

What should I do for applying patch?
I know how to work only with diff patches for kernel ;(

That is the patched ubuntu kernel.

Hi,

Okay, so, it is source code, and it has to be compiled.

Try this
- download the stuff in the user account (not the root)
- make & copy to a folder and unpack
- enter the folder
- enter "make config"
- enter "make"
- become root (sudo or something)
- do "make install" after making it back into the folder (becomming root makes you end up in the root's folder...)

Just my misty thoughts...

Luck

Or you could use make-kpkg to build a .deb

For example, instead of make install use fakeroot and make-kpkg

Code:

make oldconfig
make menuconfig
fakeroot make-kpkg -j7 --initrd --revision=1 kernel_image kernel_headers 	
make-kpkg clean

Hmm, that, of course, would be the far better option. It means using what the distro provides in terms of tools, instead of goiing hazrd-core...of course, my first Linux XP involved compiling the kernel...the hard way

Indeed.

No It isn't.

make help - Gives commands to build + configure kernel
deb-pkg - Build the kernel as an deb package
so you type: make deb-pkg

Man, did'nt know that! My way forced me (back then) to "become a friend of google"...

You misunderstood me, or I told you something wrong. I know hot to compile Linux kernel. I downloaded source from kernel.org and used following lines to build modules, kernel and install it:

Quote:

copied generic kernel 2.6.38-8 config from Ubuntu 11.04
make -j5 bzImage
make -j5 modules

make -j5 modules_install
make -j5 install

mkinitramfs -o /boot/initrd-2.6.38.8 2.6.38.8
update-grub

After booting Ubuntu 10.04 with new kernel faced troubles with network and display hardware. Search in Google gave answer that this happened due to some ubuntu specific patches were not applied (distros apply patches to vanilla kernel from kernel.org). I found that i can download kernel-source from Ubuntu packages (package contains vanilla kernel + Ubuntu patch). I've downloaded it and don't know hot to apply patch.

Is This your first time?
Them links explain everythin arse ways IMHO.

Quote:

Simple way is to download the mainline kernel from Linus's tree at kernel.org via Git - use the link found via GitWeb.
Make .config for ur devices - use "make localmodconfig" with every device attached to the system i.e plug it into the computer.
Custom the .config - "make xconfig".
Build the kernel - "make" or "make -j[num] where num is the amount of cores on the system i.e my laptop has 2 cores so "make -j2".
BUT i package it as well so i run "make -j2 deb-pkg".

If you have 2 cores, you can safely run "make -j3"

Yes it's my first time of building kernel in such way. Yes, links helped me. Currently I have no network, so can't download needed package asciidoc

I have 4 cores that is why i run -j5

Can u rollback to the generic kernel via grub - bootloader?

Yes

Issue is solved. Successfully applied Ubuntu patch on vanilla kernel and build it.
Thanks to Ubuntu Help
