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. Is there something wrong about the above procedure? Thanks! 2011/9/4 Jan Kiszka <jan.kis...@web.de>
