I'm curious if the backported patches really fixed the problem, or it just wasn't seen because the perf events version somehow wasn't getting built, or how the perf events version got built in the failing builds. 29258 2 msm-oss 2013-01-28 19:40:04 +0000 (In reply to comment #1) > I saw that this bug was supposed to be fixed by this commit: > > commit 4de6f9b17c6dd8d50ddb3050a091fae83e91bb71 > Author: Matthew McClintock <msm@freescale.com> > Date: Thu Jan 17 20:23:23 2013 +0000 > > oprofile: backport patches to fix ppc build issues > > > but when doing a ppc build for the following bug: > > https://bugzilla.yoctoproject.org/show_bug.cgi?id=3447 > > which essentially fixes a problem that prevents the 'perf events' code from > being built, so that it does get built, I still see this problem. > > I'm curious if the backported patches really fixed the problem, or it just > wasn't seen because the perf events version somehow wasn't getting built, or > how the perf events version got built in the failing builds. Tom, That's one patch from my series that I did not post yet. So, while it "fixes" so build issues it might not really fix anything. I've got some more patches on my master tree I'm testing, but again I need to figure out how to validate/test oprofile before I can submit. See my other patches here: http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=mattsm/master Again, I'm swamped... not sure when I will get to this. -M 29260 3 tom.zanussi 2013-01-28 20:37:46 +0000 OK, good to know, thanks. I'll post a couple patches shortly for bug 3447. You can follow the examples in the oprofile section if you want something to test with: https://wiki.yoctoproject.org/wiki/Tracing_and_Profiling#oprofile I just added a new section on operf, which should always be built now with the patches for 3447: https://wiki.yoctoproject.org/wiki/Tracing_and_Profiling#operf 29471 4 sgw 2013-02-01 22:21:21 +0000 This is blocking builds on the Autobuilder for PPC! 29505 5 msm-oss 2013-02-04 23:53:35 +0000 Patches post here: http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=mattsm/master&id=3a7776b96e8c558b14bb92e5fc5c0c442794862d Still need to test on a machine. 29534 6 msm-oss 2013-02-05 17:48:58 +0000 Patches submitted.
