DeRocco > Paul mailto:pdero...@ix.netcom.com I am using at the moment the raspberrypi and was able to patch with a rt patch downloaded from https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.9/ Patching, Configuring, compiling. All seems to work. Having booted the Pi i can see via uname -a, that the rt-patch is applied. The performance seems to be very nice. What is google doing about this? kind regards Michael Wiesing -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
