robox

robox is an Android container.

1. Log in to the server via SSH and enter the command line execution entry.
2. Enter a directory where the downloaded source code package is stored, such as the "/home/ubuntu" directory.
cd /home/ubuntu

3. Download the robox source code package and switch to the release-phase2.3 branch.

git clone https://github.com/lag-linaro/robox.git -b release-phase2.3

The robox source code directory is: /home/ubuntu/robox


( Source download URL: https://github.com/lag-linaro/robox.git

If the source code download fails, use the following command to skip verification:

export GIT_SSL_NO_VERIFY=1 )

robox Compile and run dependent packages

Dependent packages are packages that support robox compilation and operation. Before robox compilation, all dependent packages need to be installed.

  1. Log in to the server remotely via SSH and enter the command line execution entry.
  2. Download and install robox to compile and run dependent packages.

apt-get install build-essential cmake cmake-data debhelper dbus google-mock libboost-dev libboost-filesystem-dev libboost-log-dev libboost-iostreams-dev libboost-program-options-dev libboost-system-dev libboost-test-dev libboost-thread-dev libcap-dev libdbus-1-dev libdbus-cpp-dev libegl1-mesa-dev libgles2-mesa-dev libglib2.0-dev libglm-dev libgtest-dev liblxc1 libproperties-cpp-dev libprotobuf-dev libsdl2-dev libsdl2-image-dev lxc-dev pkg-config protobuf-compiler

docker  run dependent packages

The installation is complete before configuring docker.

  1. Log in to the server remotely via SSH and enter the command line execution portal.
  2. Download and install the docker dependency package.

  •  
    • Replace docker storage driver
    • Open a new window and perform the following operations.

      1. Log in to the server via SSH and enter the command line execution entry.
      2. View docker information.

      • docker info
    • 3. Modify the version of the storage driver.
    • If the "storage driver" version is "overlay", no adjustment is required.
      If the version of "storage driver" is "aufs", you need to change "storage driver" from "aufs" to "overlay".
        • 1) Open the "/etc/default/docker" file.

          • vim /etc/default/docker


        • 2) Add the following script.

          • DOCKER_OPTS= -s overlay

      3)It will take effect after restarting docker or reboot.

          • /etc/init.d/docker restart

  •  
    • Install Remote Desktop

Step 1 Install remote desktop.


apt install xfce4 xfce4-* xrdp


Step 2 The situation of the environment without hardware GPU configuration is as follows.


cd /home/ubuntu
vi .xsession  //Add the following in the text:xfce4-session


Step 3 Confirm after saving.


cat .xsession
xfce4-session


Step 4 Restart the xrdp remote desktop.
/etc/init.d/xrdp restart

After that, you can access the graphical desktop of the server where the Huawei Kunpeng 920 processor is located through the Windows remote desktop, and log in with the root account.

    • Incorporate Exagear transcoding patch

    • Exagear module instruction translation software supports AArch32 feature of Kunpeng cloud mobile phone scene, and ensures 100% compatibility of AArch32 instruction application.
    • 1. Create a directory.
      mkdir -p /home/compiler

      2. Download the three source files of linux_4.15.0.orig.tar.gz, linux_4.15.0-65.74.diff.gz, linux_4.15.0-65.74.dsc, and put them into the "/home/compiler/" directory.


    • The physical machine kernel source code download address: https://launchpad.net/ubuntu/+source/linux/4.15.0-65.74

      3. Enter the "/home/compiler/" directory.
      cd /home/compiler/

    • ls
      • linux_4.15.0-65.74.diff.gz  linux_4.15.0-65.74.dsc  linux_4.15.0.orig.tar.gz
    • 4. The source code directory linux-4.15.0 will be generated in the current directory.

    • dpkg-source -x linux_4.15.0-65.74.dsc


    • 5. Please extract exagear-a32a64-docker.tar.gz to the /home/ directory, and rename the decompressed folder to exagear.


    • cd /home/


    • tar zxvf exagear-a32a64-docker.tar.gz

      mv "ExaGear ARM32-ARM64 for Android Docker" exagear //Rename the purpose: to facilitate subsequent use

      cd /home/exagear

      ls

      • android //安卓源码转码补丁

      • translator //物理机上用于转码的二进制可执行文件

      • kernel //物理机内核的转码补丁

    • 6. Copy the transcoded patch to the kernel source directory.
      cp /home/exagear/kernel/ubuntu-4.15.0-65.74.patch /home/compiler/linux-4.15.0/

      cd /home/compiler/linux-4.15.0/

      patch -p1 <ubuntu-4.15.0-65.74.patch


    • Compile and install the kernel

1. Save and exit directly, and generate the configuration file .config vim .config.
make menuconfig

2. Confirm the following configuration items, if none or inconsistent, please manually change or add.
CONFIG_EXAGEAR_BT=y
CONFIG_CHECKPOINT_RESTORE=y
CONFIG_PROC_CHILDREN=y
CONFIG_VFAT_FS=y
CONFIG_INPUT_UINPUT=y

3. Compile and install.
make -j64 //compile

make modules_install //Install modules

make install // install the kernel

cd /boot/grub

sudo update-grub2 //Update startup items

4. Restart.
reboot

  •  
    • Transcode registration after the new kernel is enabled
    • 1. After the physical machine restarts, the transcoding registration is enabled.
      2. Mount the binfmt_misc file system, which is mounted by default. If it is not mounted, please execute it manually.
      mount -t binfmt_misc none /proc/sys/fs/binfmt_misc

      3. Register exagear transcoding rules, pay attention to the following multiple places to store and use the "/opt/exagear/ubt_a32a64" path information of the ubt_a32a64 transcoding binary to be consistent.
      mkdir -p /opt/exagear

      cp /home/exagear/translator/ubt_a32a64 /opt/exagear/

      cd /opt/exagear //The directory for storing transcoded binary files. When registering echo, please pay attention to /opt/exagear/ubt_a32a64

      chmod +x ubt_a32a64 //Avoid registration permission denied

    •  4. Check whether the exagear rules are successfully registered, and ensure that the "/opt/exagear/ubt_a32a64" path information is consistent.
      cat /proc/sys/fs/binfmt_misc/ubt_a32a64
  •  
    • Compile and install binder.ko and ashmem.ko modules

1. Download the kernel source code for the kernel module to compile.

apt search linux-source apt install linux-source-4.15.0 

2. Download the code and roll back to the specified version. Community link https://github.com/anbox/anbox-modules.

cd /home git clone https://github.com/anbox/anbox-modules.git

cd anbox-modules/ git reset --hard 816dd4d6e702cf77a44cfe208659af6c39e02b57

3. update ashmem and binder.

cd /home/anbox-modules

cp anbox.conf /etc/modules-load.d/

cp 99-anbox.rules /lib/udev/rules.d/

cp -rT ashmem /usr/src/anbox-ashmem-1

cp -rT binder /usr/src/anbox-binder-1

4. Compile and install using dkms.

dkms install anbox-ashmem/1

dkms install anbox-binder/1

5. Install the ko module to the kernel, and the binder_linux module needs to take parameters.

modprobe ashmem_linux

modprobe binder_linux num_devices=254

lsmod | grep -e ashmem_linux -e binder_linux

6. if the attribute permissions of ashmem and binder are not displayed by the following commands, please add the permissions with chmod.

ls -alh /dev/binder* /dev/ashmem

  •       package it through android.img and store it in docker

Import the android.img file, assuming that the Android image has been uploaded to the "/home" directory of the server where Huawei Kunpeng 920 processor is located.

1. Log in to the server by SSH and enter the command line execution portal.

2. Mount the android image to the "/mnt" directory.

Troubleshooting

  • If kernels modules successfully loaded, service is running fine, and yet Anbox won't launch with Application manager service is not running yet. Check for the message No space left on device - Failed to enter cgroup in /var/lib/anbox/logs/container.log, you may be running into see this issue: https://github.com/lxc/lxd/issues/6257
  • If container started failed

Before the container is started, session-manager needs to be started on the host to start x, input, adb and other related services, and then the container may started successful.

  • To build the Anbox runtime itself there is nothing special to know. but when we use cmake as build system. A few build dependencies need to be present on your host system:

    * libdbus
    * google-mock
    * google-test
    * libboost
    * libboost-filesystem
    * libboost-log
    * libboost-iostreams
    * libboost-program-options
    * libboost-system
    * libboost-test
    * libboost-thread
    * libcap
    * libsystemd
    * mesa (libegl1, libgles2)
    * libglm
    * libsdl2
    * libprotobuf
    * protobuf-compiler
    * python2
    * lxc (>= 3.0)
