I am fairly new to kernel compilation and installation process, still
i managed to learn from Kernelnewbies and RT-wiki and managed to patch
3.12.14 vanilla kernel with rt patch 3.14.12. Then I followed the
steps and installed rt-kernel in my lubuntu vm. While doing make
menuconfig, i selected preemtion model as BASIC-RT from processor type
and features option. It worked.
Now my confusion arises when i see my uname -a string as [Linux
paul-lubuntu 3.14.12-rt9 #2 SMP PREEMPT Tue Oct 28 13:30:27 UTC 2014
x86_64 x86_64 x86_64 GNU/Linux] which indicated that i have a
preemptive kernel installed. but the c program from RT_PREEMPT_HOWTO
section of RTwiki website for Runtime detection of an RT-PREEMPT
Kernel only prints [this is a vanilla kernel]. So, my question is am I
running a vanilla kernel or a real-time kernel? If I am not then what
are the steps to properly install a real-time kernel?
Thanking you for giving attention to my mail.

Assume you should use Debian/Ubuntu or Arch Linux I can help you to
build a kernel-rt package. As long as RT isn't mentioned in the uname -a
string, you don't run a kernel-rt. Did you copy the original config of
your installed distros's kernel, run make oldconfig and cared about
questions regarding RT?
Please consider to ask such a question at
http://lists.linuxaudio.org/listinfo/linux-audio-user instead of this
list.
