Hi, Kaiyou

Sorry, I gave you the wrong information. please do not use linux-tools-perf now. and remove the change on manifest.

Just found it's replaced by the simpleperf project under system/extras.:

On how to use simpleperf, please see it's document here: https://android.googlesource.com/platform/system/extras/+/master/simpleperf/...

And about the error of "error: .repo/manifests/: contains uncommitted changes" it's because the change on manifest. changing it back should be resolve the problem.

Thanks, Yongqin Liu

And under the linaro linux kernel tree, find perf code exist: kernel/tools/perf

Do you know how to build a perf for android platform?

thanks

it seem that external/linux-tools-perf project is not repo synced by default for aosp master,

you could add following lines in the manifest.xml, and run "repo sync external/linux-tools-perf" to repo sync it.

<project path="external/linux-tools-perf" name="platform/external/linux-tools-perf" revision="refs/tags/android-6.0.1_r55"/>

this version does not work with AOSP msater directly, you need to fix the compiling error or repo sync other projects as well.

Thanks,

I follow the instructions https://wiki.linaro.org/LMG/ Engineering/UsingPerfOnAndroid to build Perf for android

*BUILD PERF*

Make sure you've connected to your Android device.

Note: the below instructions requires an userdebug or eng build android system.

# setup your build environment first

# . build/envsetup.sh

m -j 32 perf

adb sync

But it failed when execute the command “m -j 32 perf”,
