[Kernel-packages] [Bug 1641859] Re: perf compiled without auxtrace
I haven't tried any previous Ubuntu or kernel releases. I'm not doing anything special to compile perf myself, i.e., I just run make in tools/perf. Looking at tools/perf/Makefile.config, it seems like auxtrace gets disabled if GCC is detected to not have __get_cpuid, which makes it seems like a bug in the feature detection or an abnormality in the environment where perf is built for linux-tools-common. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1641859 Title: perf compiled without auxtrace Status in linux package in Ubuntu: Triaged Bug description: perf in linux-tools-common_4.8.0-27.29 seems to be compiled without auxtrace support.
