Re: [Xenomai-core] xenomai-core ftrace
you mean I use remotes/origin/queues/2.6.37-x86 branch and use the ipipe patch for 2.6.37 then install them on x86_64, the ftrace can work?I will have a try, thank you! 2011/9/4 Jan Kiszka jan.kis...@web.de On 2011-09-04 07:10, rainbow wrote: 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 That's a build issues of the underlying old ipipe patch.

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 :) .
