| 2 | ========================================= |

| 4 | I. Set the Android NDK environment |
| 5 | ------------------------------------------------ |
| 6 | |
| 7 | (a). Use the Android NDK |
| 8 | ------------------------------------------------ |
| 9 | 1. You need to download and install the Android Native Development Kit (NDK). |
| 10 | Set the NDK variable to point to the path where you installed the NDK: |
| 11 | export NDK=/path/to/android-ndk |
| 12 | |
| 13 | 2. Set cross-compiling environment variables for NDK toolchain and sysroot. |
| 14 | For arm: |

| 16 | export NDK_SYSROOT=${NDK}/platforms/android-24/arch-arm |
Irina Tirdea | 7747e2f | 2012-10-08 09:43:28 +0300 | [diff] [blame] | 17 | For x86: |
Chris Phlipot | 3d03761 | 2016-06-30 22:12:35 -0700 | [diff] [blame] | 18 | export NDK_TOOLCHAIN=${NDK}/toolchains/x86-4.9/prebuilt/linux-x86_64/bin/i686-linux-android- |
| 19 | export NDK_SYSROOT=${NDK}/platforms/android-24/arch-x86 |
Irina Tirdea | 7747e2f | 2012-10-08 09:43:28 +0300 | [diff] [blame] | 20 | |
Chris Phlipot | 3d03761 | 2016-06-30 22:12:35 -0700 | [diff] [blame] | 21 | This method is only tested for Android NDK versions Revision 11b and later. |
| 22 | perf uses some bionic enhancements that are not included in prior NDK versions. |
Irina Tirdea | 7747e2f | 2012-10-08 09:43:28 +0300 | [diff] [blame] | 23 | You can use method (b) described below instead. |
| 24 | |
| 25 | (b). Use the Android source tree |
| 26 | ----------------------------------------------- |
| 27 | 1. Download the master branch of the Android source tree. |
| 28 | Set the environment for the target you want using: |
| 29 | source build/envsetup.sh |
| 30 | lunch |
| 31 | |
| 32 | 2. Build your own NDK sysroot to contain latest bionic changes and set the |
| 33 | NDK sysroot environment variable. |
| 34 | cd ${ANDROID_BUILD_TOP}/ndk |
| 35 | For arm: |
| 36 | ./build/tools/build-ndk-sysroot.sh --abi=arm |
| 37 | export NDK_SYSROOT=${ANDROID_BUILD_TOP}/ndk/build/platforms/android-3/arch-arm |
| 38 | For x86: |
| 39 | ./build/tools/build-ndk-sysroot.sh --abi=x86 |
| 40 | export NDK_SYSROOT=${ANDROID_BUILD_TOP}/ndk/build/platforms/android-3/arch-x86 |
| 41 | |
| 42 | 3. Set the NDK toolchain environment variable. |
| 43 | For arm: |
| 44 | export NDK_TOOLCHAIN=${ANDROID_TOOLCHAIN}/arm-linux-androideabi- |
| 45 | For x86: |
| 46 | export NDK_TOOLCHAIN=${ANDROID_TOOLCHAIN}/i686-linux-android- |
| 47 | |
| 48 | II. Compile perf for Android |
| 49 | ------------------------------------------------ |
| 50 | You need to run make with the NDK toolchain and sysroot defined above: |

Chris Phlipot | 3d03761 | 2016-06-30 22:12:35 -0700 | [diff] [blame] | 52 | make WERROR=0 ARCH=arm CROSS_COMPILE=${NDK_TOOLCHAIN} EXTRA_CFLAGS="-pie --sysroot=${NDK_SYSROOT}" |
Joonsoo Kim | cd69ef8 | 2012-10-29 22:41:06 +0900 | [diff] [blame] | 53 | For x86: |
Chris Phlipot | 3d03761 | 2016-06-30 22:12:35 -0700 | [diff] [blame] | 54 | make WERROR=0 ARCH=x86 CROSS_COMPILE=${NDK_TOOLCHAIN} EXTRA_CFLAGS="-pie --sysroot=${NDK_SYSROOT}" |

| 56 | III. Install perf |
| 57 | ----------------------------------------------- |
| 58 | You need to connect to your Android device/emulator using adb. |
| 59 | Install perf using: |
| 60 | adb push perf /data/perf |
| 61 | |
| 62 | If you also want to use perf-archive you need busybox tools for Android. |
| 63 | For installing perf-archive, you first need to replace #!/bin/bash with #!/system/bin/sh: |
| 64 | sed 's/#!\/bin\/bash/#!\/system\/bin\/sh/g' perf-archive >> /tmp/perf-archive |
| 65 | chmod +x /tmp/perf-archive |
| 66 | adb push /tmp/perf-archive /data/perf-archive |
| 67 | |
| 68 | IV. Environment settings for running perf |
| 69 | ------------------------------------------------ |
| 70 | Some perf features need environment variables to run properly. |
| 71 | You need to set these before running perf on the target: |
| 72 | adb shell |
| 73 | # PERF_PAGER=cat |
| 74 | |
| 75 | IV. Run perf |
| 76 | ------------------------------------------------ |
| 77 | Run perf on your device/emulator to which you previously connected using adb: |
| 78 | # ./data/perf |
