Hi all, The preload kmp is failing again in Kernel:stable. I can't seem to figure out where the "canonical" version of this code is at in order to fix it. Anyone know which repo is the "real" one? Is it the one in Kernel:HEAD? If so, it's failing there as well :) Actually, why do we require this kmp in the first place? I'm getting tired of having it keep the Tumbleweed kernel updates from pushing out to users properly. If it's so necessary, shouldn't we merge the thing upstream? thanks, greg k-h -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

And please don't tell me that the only "tree" for the preload.tar.gz file is in the build system packages, surely it's kept in a tree somewhere else so we can track modifications for it and the like, right? thanks, greg k-h -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

confused,

The build does: mkdir source cp stap/preloadtrace.stp stap/Kbuild source touch source/preloadtrace.c kernels=`cd /usr/lib/debug/lib/modules && ls -1d *-$flavor ` cp -r source obj/$flavor make -C /usr/src/linux-obj/%_target_cpu/$flavor modules M=$PWD/obj/$flavor stap -p 4 -DMAXSTRINGSIZE=300 -DMAXSKIPPED=2000 -r $kernels -m preloadtrace obj/$flavor/preloadtrace.stp mv preloadtrace.ko obj/$flavor So I guess it is basically building on an empty .c file but with stap script in.

Thanks for the help. As I'm stuck in Tokyo due to plane problems, I tried to take some time to look into fixing it. Building the preload module from the svn tree seems to work fine, but from the spec file, it dies with the following errors: /tmp/stapr2YkJ8/preloadtrace.c: In function 'function_gettimeofday_ns': /tmp/stapr2YkJ8/preloadtrace.c:2291:3: error: implicit declaration of function '_stp_gettimeofday_ns' /tmp/stapr2YkJ8/preloadtrace.c: In function 'systemtap_module_init': /tmp/stapr2YkJ8/preloadtrace.c:5448:3: error: implicit declaration of function '_stp_init_time' /tmp/stapr2YkJ8/preloadtrace.c:5703:4: error: implicit declaration of function '_stp_kill_time' make[3]: *** [/tmp/stapr2YkJ8/preloadtrace.o] Error 1 Which kind of implies that it's a system tap issue somewhere. Do we need to update the system tap version in Kernel:HEAD somehow?

Well, preload doesn't contain any kernel code, modules or otherwise. It contains a systemtap script. And the latter happens to be implemented via kernel modules. Not my fault.

Yeah, in looking at this further, I think I agree, but unwinding the systemtap stuff is a mess... thanks, greg k-h -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
