The binary available already in the build is an older perf binary which will not work. Perf compilation is disabled since it fails with this error: android/ out/target/ product/ vexpress/ obj/kernel/ tools/perf/ perf android/ prebuilts/ gcc/linux- x86/arm/ arm-linux- androideabi- 4.7-linaro/ bin/../ libexec/ gcc/arm- linux-androidea bi/4.7. 3/real- ld: error: /data/src/ android/ out/target/ product/ vexpress/ obj/kernel/ tools/perf/ liblk.a( debugfs. o): incompatible target mountpoint' mountpoint' events. c:981: error: undefined reference to 'debugfs_ find_mountpoint ' events. c:163: error: undefined reference to 'debugfs_ valid_mountpoin t' events. c:460: error: undefined reference to 'debugfs_ valid_mountpoin t' events. c:949: error: undefined reference to 'debugfs_ valid_mountpoin t' events. c:998: error: undefined reference to 'debugfs_ valid_mountpoin t' src/android/ out/target/ product/ vexpress/ obj/kernel/ tools/perf/ perf] Error 1 src/android/ kernel/ linaro/ vexpress/ tools/perf'
