I tried to compile the UDOO kernel from https://github.com/UDOOboard/Kernel_Unico with the RT_PREEMPT patch from https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO applied. Unfortunately the patch can not patch all files, due to the changes made for the UDOO board. The following files are rejected: ./Kernel_Unico_patched/arch/arm/kernel/smp.c.rej ./Kernel_Unico_patched/arch/arm/kernel/process.c.rej ./Kernel_Unico_patched/arch/arm/common/gic.c.rej ./Kernel_Unico_patched/kernel/rtmutex.c.rej ./Kernel_Unico_patched/include/linux/plist.h.rej ./Kernel_Unico_patched/include/linux/rtmutex.h.rej ./Kernel_Unico_patched/drivers/misc/Makefile.rej Has anyone managed to compile the UDOO kernel with this patch applied and would be willing to share the sources? Kind Regards, Andreas
You just need to fix this issues yourself (I look quickly and saw there are only small changes required). As stated those patches are for vanilla kernel source. Or you can try 4.0.8 kernel from patrykk and apply patch on top of it without a problem.
