**** BEGIN LOGGING AT Thu Apr 09 02:59:58 2015 Apr 09 08:53:12 I was going through the APM_Linux paper and wanted to understand about the RT aspects of the kernel Apr 09 08:58:33 In the paper the vanilla kernel compiled with the PREEMPT performed better so I expected the kernel used would be a stable branch. But in http://dev.ardupilot.com/wiki/building-the-code/building-for-beaglebone-black-on-linux/#compiling_the_beaglebone_black_kernel-2 a specific branch with a name 3.8-rt is used? Apr 09 09:08:31 So my doubt is why not use the 3.8 branch and enable CONFIG_PREEMPT Apr 09 09:20:41 zeuzoix, CONFIG_PREEMPT and PREEMPT RT PATCH are different points, google and you will know, 3.8rt has rt preempt patch but 3.8 doesn't Apr 09 09:21:53 So 3.8rt has the PREEMPT RT patch? Apr 09 09:24:16 Is the PREEMPT RT patch the same as the CONFIG_PREEMPT_RT patch? **** ENDING LOGGING AT Fri Apr 10 02:59:59 2015
