How to make a real-time Linux kernel, the Debian way

A Real-Time Operating System (RTOS; generally pronounced as "R-toss") is a multitasking operating system intended for real-time applications. Such applications include embedded systems (programmable thermostats, household appliance controllers), industrial robots, spacecraft, industrial control (see SCADA), and scientific research equipment.

We need how to compile a kernel, like thru this guide.
For our task, we need the kernel sources (vanilla or debian) and the real-time patch, that you can get here (must match your kernel version).

[sourcecode language='php']apt-get install linux-sources
cd /usr/src/linux-source
patch -p1 cp /boot/config-`uname -a` .config
make oldconfig
make menuconfig[/sourcecode]

[*] Wakeup latency timing
[*] Latency tracing
[*] wakeup latency histogram

Kernel hacking --->
[ ] Check for stack overflows

[sourcecode language='php']make-kpkg --initrd --append-to-version=-rt kernel_image
dpkg -i ../linux-image-*.deb
reboot[/sourcecode]

Be happy now! :)
