1 How to compile perf for Android
2 =========================================
3
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 Androi
10 Set the NDK variable to point to the path wher
11 export NDK=/path/to/android-ndk
12
13 2. Set cross-compiling environment variables f
14 For arm:
15 export NDK_TOOLCHAIN=${NDK}/toolchains/arm-l
16 export NDK_SYSROOT=${NDK}/platforms/android-
17 For x86:
18 export NDK_TOOLCHAIN=${NDK}/toolchains/x86-4
19 export NDK_SYSROOT=${NDK}/platforms/android-
20
21 This method is only tested for Android NDK ver
22 perf uses some bionic enhancements that are no
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 s
28 Set the environment for the target you want us
29 source build/envsetup.sh
30 lunch
31
32 2. Build your own NDK sysroot to contain lates
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/
38 For x86:
39 ./build/tools/build-ndk-sysroot.sh --abi=x86
40 export NDK_SYSROOT=${ANDROID_BUILD_TOP}/ndk/
41
42 3. Set the NDK toolchain environment variable.
43 For arm:
44 export NDK_TOOLCHAIN=${ANDROID_TOOLCHAIN}/ar
45 For x86:
46 export NDK_TOOLCHAIN=${ANDROID_TOOLCHAIN}/i6
47
48 II. Compile perf for Android
49 ----------------------------------------------
50 You need to run make with the NDK toolchain an
51 For arm:
52 make WERROR=0 ARCH=arm CROSS_COMPILE=${NDK_T
53 For x86:
54 make WERROR=0 ARCH=x86 CROSS_COMPILE=${NDK_T
55
56 III. Install perf
57 ----------------------------------------------
58 You need to connect to your Android device/emu
59 Install perf using:
60 adb push perf /data/perf
61
62 If you also want to use perf-archive you need
63 For installing perf-archive, you first need to
64 sed 's/#!\/bin\/bash/#!\/system\/bin\/sh/g'
65 chmod +x /tmp/perf-archive
66 adb push /tmp/perf-archive /data/perf-archiv
67
68 IV. Environment settings for running perf
69 ----------------------------------------------
70 Some perf features need environment variables
71 You need to set these before running perf on t
72 adb shell
73 # PERF_PAGER=cat
74
75 IV. Run perf
76 ----------------------------------------------
77 Run perf on your device/emulator to which you
78 # ./data/perf
