Hi
there's no PAE for my 64-bit configuration
, but anyway you should be
able to disable PAE by using menuconfig and then search for PAE, resp.
you can use gedit and do the same as described for XEN. It's described
later in this howto.
### Open a terminal
Push Alt + F2
Typ gnome-terminal
Click Run
Take care, in this email the lines might be wrapped. For the terminal
anything behind the command must not be wrapped.
### Get needed software
spinymouse-sudo@64studio:~$ sudo apt-get update
spinymouse-sudo@64studio:~$ sudo apt-get install bin86 build-essential
bzip2 fakeroot gcc kernel-package make libncurses5-dev
### Download the kernel sources
spinymouse-sudo@64studio:~$ wget
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.31.6-rt19.bz2
spinymouse-sudo@64studio:~$ wget
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.31.6.tar.bz2
### Extracting the sources and others
spinymouse-sudo@64studio:~$ tar xvjf linux-2.6.31.6.tar.bz2
spinymouse-sudo@64studio:~$ rm linux-2.6.31.6.tar.bz2
spinymouse-sudo@64studio:~$ mv linux-2.6.31.6 linux-2.6.31.6-rt19
spinymouse-sudo@64studio:~$ ln -s linux-2.6.31.6-rt19 linux
spinymouse-sudo@64studio:~$ cd linux
spinymouse-sudo@64studio:~/linux$ mv ../patch-2.6.31.6-rt19.bz2 ~/linux
spinymouse-sudo@64studio:~/linux$ bunzip2 patch-2.6.31.6-rt19.bz2
### Patching the vanilla kernel with the real-time patch and others
spinymouse-sudo@64studio:~/linux$ patch -p1 < patch-2.6.31.6-rt19
spinymouse-sudo@64studio:~/linux$ rm patch-2.6.31.6-rt19
### Make sure that you have booted the default multimedia kernel (Your
kernel might be x86)
spinymouse-sudo@64studio:~/linux$ uname -r
2.6.29-1-multimedia-amd64
### Copy the configuration of 64 Studio's default kernel
spinymouse-sudo@64studio:~/linux$ cp /boot/config-$(uname -r) .config
### Setting up a new configuration
spinymouse-sudo@64studio:~/linux$ make oldconfig
###
You can ignore warnings.
Always just enter when you get asked anything.
### I couldn't find PAE, but XEN and when XEN is enabled, PAE is enabled
too. Dunno if disabling XEN will disable PAE too.
spinymouse-sudo@64studio:~/linux$ cat .config | grep PAE
spinymouse-sudo@64studio:~/linux$ cat .config | grep pae
spinymouse-sudo@64studio:~/linux$ cat .config | grep XEN
CONFIG_XEN=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=32
CONFIG_XEN_SAVE_RESTORE=y
# CONFIG_XEN_DEBUG_FS is not set
CONFIG_XEN_BLKDEV_FRONTEND=m
# CONFIG_NETXEN_NIC is not set
CONFIG_XEN_NETDEV_FRONTEND=m
CONFIG_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
CONFIG_XEN_FBDEV_FRONTEND=y
CONFIG_XEN_BALLOON=y
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
### Disabling XEN
spinymouse-sudo@64studio:~/linux$ gedit .config
###
Push Ctrl + F (resp. Strg + F)
Wrap around search for: CONFIG_XEN
By Pushing the Find-button you should find all CONFIG_XENs that were
listed by "cat .config | grep XEN".
###
Replace "CONFIG_XEN=y" by "# CONFIG_XEN is not set".
Keep those "# CONFIG_XEN" that beginn with a hash (#).
Delete all the other "CONFIG_XEN" that don't beginn with the hash.
###
Push Ctrl + F (resp. Strg + F)
Wrap around search for: XEN
Find and delete any line were "XEN" is included as an own word.
E.g. delete "CONFIG_HVC_XEN=y"
###
Save .config and close gedit.
### Cat now should display something similar to this:
spinymouse-sudo@64studio:~/linux$ cat .config | grep XEN
# CONFIG_XEN is not set
# CONFIG_XEN_DEBUG_FS is not set
# CONFIG_NETXEN_NIC is not set
All "XEN" must be disabled.
### Again running make oldconfig should look similar like this:
spinymouse-sudo@64studio:~/linux$ make oldconfig
scripts/kconfig/conf -o arch/x86/Kconfig
#
# configuration written to .config
#
### Now search for PAE by using menuconfig
spinymouse-sudo@64studio:~/linux$ make menuconfig
###
Enter: Load an Alternate Configuration File
Load : .config
###
Maybe I didn't search long enough, but I didn't found PAE. If you
should find PAE, disable it and ...
... enter: Save an Alternate Configuration File
Save : .config
< Exit >
### Tidy up
spinymouse-sudo@64studio:~/linux$ make-kpkg clean
### Build the kernel
spinymouse-sudo@64studio:~/linux$ make-kpkg --rootcmd fakeroot --initrd
kernel-image kernel-headers kernel-source
Using an AMD Athlon 2.1 GHz dual core processor it nearly takes 90
minutes to compile the kernel. Dunno if there's a job option for
make-kpkg, if there should be one, you can start more than one job, thus
the compiling will go faster.

### Configuring linux-image-2.6.31.6-rt19
What would you like to do about menu.lst?
Enter: keep the local version currently installed
### Editing menu.lst
E.g.
spinymouse-sudo@64studio:~$ sudo gedit /media/suse11.2/boot/grub/menu.lst
Your might need to run
spinymouse-sudo@64studio:~$ gedit /boot/grub/menu.lst
instead, for 64 Studio's bootloader. I'm using the bootloader from
another installation.
There are lines similar to those:
title 64 Studio, kernel 2.6.29-1-multimedia-amd64
root (hd0,5)
kernel /boot/vmlinuz-2.6.29-1-multimedia-amd64

Add new lines, but change 2.6.29-1-multimedia-amd64 to the name of your
new kernel.
The kernels are in /boot:
