hi, I did a test for ftrace-xenomai on x86_64 test just now: the environment is : OS: debian 6.0 gcc-4.1 I use origin/queues/2.6.37-x86 branch on git git://git.kiszka.org/ipipe-2.6for linux kernel and use branch origin/queues/ftrace on git git:// git.xenomai.org/xenomai-jki.git then I do as the following procedures: 1,cd xenomai git 2, ./scripts/prepare-kernel.sh --arch=x86_64 --linux=path_to_2.6.37-x86 3, cd path_to_2.6.37_x86 4,make menuconfig then enble ftrace on kernel hacking option. 5,install the kernel and reboot the machine. 6,do ftrace test 6.1 mount -t debugfs nodev /sys/kernel/debug 6.2 cd /sys/kernel/debug/tracing 6.3 echo function > current_tracer At last the machine reboot.

First of all, make sure to read README.INSTALL in the Xenomai tree for the basic installation procedure. That git branch above replaces the installation step of picking a vanilla Linux source tree and applying the ipipe patch to it (if there is no ipipe option in the kernel config, you probably haven't check out the right branch yet). The next step would be running Xenomai's prepare-kernel.sh, in this case using a Xenomai tree that has the required ftrace patches, see http://permalink.gmane.org/gmane.linux.real-time.xenomai.devel/7966 Jan signature.asc Description: OpenPGP digital signature ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
