Hello,
I'm running
https://android-build.linaro.org/builds/~linaro-android/panda-jb-gcc47-tilt-tracking-blob,
build 23 (Aug15). It's kernel version is 3.4.0-xxx, but 'perf --version'
reports 3.0.8_android.
Why such a version mismatch? Usually it's the very poor idea to run perf on
top of mismatched
Is that really true. Isn't it supposed to be backwards compatible ?
The perf.data format is designed with some compatibility in mind,
so 3.0.8_android should read any recent enough (say, from perf >= 3.0)
perf.data at least. But if perf can't record anything due to a wrong
kernel version, it's almost useless.
