+# AutoFDO profiles for Android common kernels
+
+This directory contains AutoFDO profiles for Android common kernels. These profiles can be used to
+optimize kernel builds for specific architectures and kernel versions.
+
+## kernel.afdo
+
+kernel.afdo is an AArch64 kernel profile collected on kernel version 6.12.18 (
+SHA fbd1fef4d7283d210845f8609599efd53c0905a4, build server ID 13287522) using Pixel 6.
+
+### Performance improvements
+
+| Benchmark             | Improvement |
+| --------------------- | ----------- |
+| Boot time             | 2.6%        |
+| Cold App launch time  | 3.7%        |
+| Binder-rpc            | 9.4%        |
+| Binder-addints        | 31.9%       |
+| Hwbinder              | 16.5%       |
+| Bionic (syscall_mmap) | 7.1%        |
+| Bionic (pthread)      | 3.3%        |
+| Bionic (stdio)        | 3.7%        |
+| Bionic (all)          | 3.4%        |
+
+Benchmark results were tested on Pixel 6.
+
+To test a kernel prebuilt with the AutoFDO profile, navigate to [Android build server](
+https://ci.android.com/builds/branches/aosp_kernel-common-android16-6.12/grid) and download
+the kernel prebuilts under the `kernel_aarch64_autofdo` target.
+
+## Steps to reproduce the profile
+
+A kernel profile is generated by running app crawling and app launching for top 100 apps from Google
+Play Store. While running, we collect ETM data for the kernel, which records executed instruction
+stream. Finally, we merge and convert ETM data to one AutoFDO profile.
+
+1. Build a kernel image and flash it on an Android device
+  * The source code and test device used to generate each profile are described above.
+  * We use a Pixel device. But using other real devices should get a similar profile.
+
+2. Run app crawling and app launching for top 100 apps
+  * Add a gmail account on the test device. Because app crawler can use the account to automatically
+    login some of the apps.
+  * We run [App Crawler](https://developer.android.com/studio/test/other-testing-tools/app-crawler)
+    for one app for 3 minutes, and run it twice.
+  * We run app launching for one app for 3 seconds, and run it 15 times. After each running, the
+    app is killed and cache is cleared. So we get profile for cold app startups.
+
+3. Record ETM data while running app crawling and app launching.
+  * We use cmdline `simpleperf record -e cs-etm:k -a` to [record ETM data for the kernel](https://android.googlesource.com/platform/system/extras/+/master/simpleperf/doc/collect_etm_data_for_autofdo.md).
