Re: [Xenomai-core] xenomai-core ftrace
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?

Re: [Xenomai-core] xenomai-core ftrace
Is the ipipe patch the same as patch like adeos-ipipe-2.6.37.6-x86-2.9-02.patch, I know the latter is xenomai patch and after I patch it, I can see "Real-time sub-system ---> " Option. But If I use 2.6.35-x86-trace which contains ,there is no such option. Another problem is that there are so many xenomai gits , how can i download the correct git? I am a newby to xenomai and I am sorry to ask so many questions but I want to do something on xenomai :) .

Re: [Xenomai-core] xenomai-core ftrace
Sorry to reply so late, I did a test about install ftrace on xenomai. the following is my procedure: #git://git.xenomai.org/xenomai-jki.git queues/ftrace #git://git.kiszka.org/ipipe-2.6 queues/2.6.35-x86-trace #cd queues/ftrace #git checkout -b remotes/origin/queues/ftrace origin/queues/2.6.35-x86-trace //change to the ftrace xenomai branch #cd ../2.6.35-x86-trace #git checkout -b origin/queues/2.6.35-x86-trace origin/queues/2.6.35-x86-trace #cd ../ftrace #./scripts/prepare-kernel.sh --arch=i386 --adeos=ksrc/arch/x86/patches/adeos-ipipe-2.6.35.9-x86-2.8-04.patch --linux=../2.6.35-x86-trace/ #cd /2.6.35-x86-trace/ then I compile the kernel but I get the following error message: arch/x86/kernel/ipipe.c:851: error: conflicting types for ‘update_vsyscall’ include/linux/clocksource.h:316: note: previous declaration of ‘update_vsyscall’ was here make[2]: *** [arch/x86/kernel/ipipe.o] Error 1 make[1]: *** [arch/x86/kernel] Error 2 make: *** [arch/x86] Error 2 I am not sure the reason is that I get the wrong patch or the kernel configuration is wrong, Is the procedure above right?

[Xenomai-core] xenomai-core ftrace
hi,all,I want to use ftrace in xenomai-2.5.6,but when I use git:// git.kiszka.org/ipipe.git queues/2.6.35-x86-trace to get the linux kernel,there is no option about xenomai or ipipe . If I want to patch the xenomai patch,there are some problem.
