-BCC (BPF compiler collection) for Android
-=========================================
-
-Introduction
-------------
-BCC is a compiler and a toolkit, containing powerful kernel tracing tools that
-trace at the lowest levels, including adding hooks to functions in kernel space
-and user space to deeply understand system behavior while being low in
-overhead. [Here's a presentation with an
-overview](http://www.joelfernandes.org/resources/bcc-ospm.pdf) and visit [BCC's
-project page](https://github.com/iovisor/bcc) for the official BCC
-documentation.
-
-Quick Start
------------
-adeb is the primary vehicle for running BCC on Android. It supports
-preparing the target Android device with necessary kernel headers, cloning and
-building BCC on device, and other setup. Take a look a quick look at [adeb
-README](https://github.com/joelagnel/adeb/blob/master/README.md) so that
-you're familiar with what it is.
-
-To download a prebuilt filesystem with BCC already built/installed for an ARM64
-device, you can just run:
-```
-adeb prepare --full
-```
-
-This downloads the FS and also downloads prebuilt kernel headers after
-detecting your device's kernel version. Running BCC this way may cause a warning
-at startup since the headers may not be an *exact* match for your kernel's
-sublevel (only version and patchlevel are matched), however it works well in
-our testing and could be used, as long as you can tolerate the warning.
-
-If you would like to setup your own kernel headers and prevent the warning,
-you can point adeb to the kernel sources which will extract headers from there:
-```
-adeb prepare --full --kernelsrc /path/to/kernel-source/
-```
-For targets other than ARM64, see the [Other Architectures
-section](https://github.com/joelagnel/adeb/blob/master/BCC.md#other-architectures-other-than-arm64)
-
-Now to run BCC, just start an adeb shell: `adeb shell`. This uses adb
-as the backend to start a shell into your adeb environment. Try running
-`opensnoop` or any of the other BCC tracers to confirm that the setup worked
-correctly.
-
-If building your own kernel, following are the kernel requirements:
-
-You need kernel 4.9 or newer. Anything less needs backports. Your kernel needs
-to be built with the following config options at the minimum:
-```
-CONFIG_KPROBES=y
-CONFIG_KPROBE_EVENT=y
-CONFIG_BPF_SYSCALL=y
-```
-Optionally,
-```
-CONFIG_UPROBES=y
-CONFIG_UPROBE_EVENT=y
-```
-Additionally, for the criticalsection BCC tracer to work, you need:
-```
-CONFIG_DEBUG_PREEMPT=y
-CONFIG_PREEMPTIRQ_EVENTS=y
-```
-
-Build BCC during adeb install (Optional)
---------------------------------------------
-If you would like the latest upstream BCC built and installed on your Android
-device, you can run:
-```
-adeb prepare --build --bcc --kernelsrc /path/to/kernel-source/
-```
-NOTE: This is a slow process and can take a long time. Since it not only builds
-BCC but also installs all non-BCC debian packages onto the filesystem and configures them.
-
-Other Architectures (other than ARM64)
------------------------
-By default adeb assumes the target Android device is based on ARM64
-processor architecture. For other architectures, use the --arch option. For
-example for x86_64 architecture, run:
-```
-adeb prepare --arch amd64 --build --bcc --kernelsrc /path/to/kernel-source/
-```
-Note: The --download option ignores the --arch flag. This is because we only
-provide pre-built filesystems for ARM64 at the moment.
-Note: If you pass --arch, you have to pass --build, because prebuilt
-filesystems are not available for non-arm64 devices.
-
-Common Issues
--------------
-Here are some common issues you may face when running different BCC tools.
-
-* Issue 1: Headers are missing on the target device.
-
-Symptom: This will usually result in an error like the following:
-```
-root@localhost:/# criticalstat
-
-In file included from <built-in>:2
-In file included from /virtual/include/bcc/bpf.h:12:
-In file included from include/linux/types.h:5:

-```
-
-* Issue 2: `CONFIG_KPROBES` isn't enabled.
-
-Symptom: This will result in an error like the following:
-```

-```
-
-* Issue 3: `CONFIG_BPF_SYSCALL` isn't enabled.
-
-Symptom: This may result in a compilation error like the following:
-```

-adeb
---------
-
-**adeb** (also known as **androdeb**) provides a powerful Linux shell
-environment where one can run popular and mainstream Linux tracing, compiling,
-editing and other development tools on an existing Android device. All the
-commands typically available on a modern Linux system are supported in
-adeb.
-
-Usecases
---------
-1. Powerful development environment with all tools ready to go (editors,
-compilers, tracers, perl/python etc) for your on-device development.
-
-2. No more cross-compiler needed: Because it comes with gcc and clang, one can
-build target packages natively without needing to do any cross compilation. We even
-ship git, and have support to run apt-get to get any missing development packages
-from the web.
-
-3. Using these one can run popular tools such as BCC that are difficult to run
-in an Android environment due to lack of packages, dependencies and
-cross-compilation needed for their operation. [Check BCC on Android using
-adeb](https://github.com/joelagnel/adeb/blob/master/BCC.md) for more
-information on that.
-
-4. No more crippled tools: Its often a theme to build a static binary with
-features disabled, because you couldn't cross-compile the feature's dependencies. One
-classic example is perf. However, thanks to adeb, we can build perf natively
-on device without having to cripple it.
-
-Requirements for running
-------------------------
-Target:
-An ARM64 android N or later device which has "adb root" supported. Typically
-this is a build in a userdebug configuration. Device should have atleast 2 GB
-free space in the data partition. If you would like to use other architectures,
-see the [Other Architectures](https://github.com/joelagnel/adeb/blob/master/README.md#how-to-use-adeb-for-other-architectures-other-than-arm64) section.
-
-Host:
-A machine running recent Ubuntu or Debian, with 4GB of memory and 4GB free space.
-Host needs debootstrap and qemu-debootstrap packages.
-To install it, run `sudo apt-get install qemu-user-static debootstrap`.
-Other distributions may work but they are not tested.
-
-Quick Start Instructions
-------------------------
-* First clone this repository into adb and cd into it.
-```
-cd adeb
-
-# Add some short cuts:
-sudo ln -s $(pwd)/adeb /usr/bin/adeb
-
-# Cached image downloads result in a huge speed-up. These are automatic if you
-# cloned the repository using git. However, if you downloaded the repository
-# as a zip file (or you want to host images elsewere), you could set the
-# ADEB_REPO_URL environment variable in your bashrc file.
-# Disclaimer: Google is not liable for the below URL and this
-# is just an example.
-export ADEB_REPO_URL="github.com/joelagnel/adeb/"
-```
-
-* Installing adeb onto your device:
-First make sure device is connected to system
-Then run, for the base image:
-```
-adeb prepare
-```
-The previous command only downloads and installs the base image.
-Instead if you want to download and install the full image, do:
-```
-adeb prepare --full
-```
-
-* Now run adeb shell to enter your new environment!:
-```
-adeb shell
-```
-
-* Once done, hit `CTRL + D` and you will exit out of the shell.
-To remove adeb from the device, run:
-```
-adeb remove
-```
-If you have multiple devices connected, please add `-s <serialnumber>`.
-Serial numbers of all devices connected can be obtained by `adb devices`.
-
-* To update an existing adeb clone on your host, run:
-```
-adeb git-pull
-```
-
-More advanced usage instructions
---------------------------------
-### Install kernel headers in addition to preparing adeb device:
-```
-adeb prepare --kernelsrc /path/to/kernel-source
-```
-
-### Update kernel headers onto an already prepared device:
-
-If you need to put kernel sources for an existing install, run:
-```
-adeb prepare --kernelsrc /path/to/kernel-source --skip-install
-```
-Note: The kernel sources should have been built (atleast build should have started).
-
-### Build and prepare device with a custom rootfs locally:
-
-The adeb fs will be prepared locally by downloading packages as needed:
-```
-adeb prepare --build
-```
-This is unlike the default behavior, where the adeb rootfs is itself pulled from the web.
-
-If you wish to do a full build (that is locally prepare a rootfs with all packages, including bcc, then do):
-```
-adeb prepare --full --build
-```
-
-### Add kernel headers to device in addition to building locally:
-```
-adeb prepare --build --kernelsrc /path/to/kernel-source/
-```
-
-### Build/install a base image with BCC:
-```
-adeb prepare --build --bcc --kernelsrc /path/to/kernel-source/
-```
-Note: BCC is built from source. Also `--kernelsrc` is recommended for tools to
-function unless device has them already.
-
-### Extract the FS from the device, after its prepared:
-```
-adeb prepare --buildtar /path/
-```
-After device is prepared, it will extract the root fs from it
-and store it as a tar archive at `/path/adeb-fs.tgz`. This
-can be used later.
-
-### Use a previously prepared adeb rootfs tar from local:
-```
-adeb prepare --archive /path/adeb-fs.tgz
-```
-
-### Build a standalone raw EXT4 image out of the FS:
-```
-adeb prepare --build-image /path/to/image.img
-```
-This can then be passed to Qemu as -hda. Note: This option doesn't need a
-device connected.
-
-### How to use adeb for other Architectures (other than ARM64)
-By default adeb assumes the target Android device is based on ARM64
-processor architecture. For other architectures, use the --arch option. For
-example for x86_64 architecture, run:
-```
-adeb prepare --build --arch amd64 --bcc --kernelsrc /path/to/kernel-source/
-```
-Note: The --download option ignores the --arch flag. This is because we only
-provide pre-built filesystems for ARM64 at the moment.
-
-Common Trouble shooting
------------------
-1. Installing g++ with `apt-get install g++` fails.
-
-Solution: Run `adeb shell apt-get update` after the `adeb prepare` stage.
-
-2. It's too slow to use debootstrap to create debian fs
-
-Solution: Use a local mirror, for example in China you could use
-https://mirror.tuna.tsinghua.edu.cn/debian/ instead of debian official website
-http://deb.debian.org/debian/
