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. -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
