Virtual Input manger uses uinput framework to create virtual/user-space input devices & virtio-input infrastructure from QEmu to map the devices on virtual machines

How to Compile

Prerequisite:

  • Required minimum gcc version is 7.4.0 or Ubuntu 18.04 release of Ubuntu Host

Compile:

  • $make clean
  • $make
  • Compilation generates vinput-manager & sendkey executables.

Follow below steps to check volume and power button functionality in CIV-GVTG

Step 1:

  • Pre-built binaries are placed in ~/civ/scripts directory
  • $cd ~/civ/scripts/
  • $chmod +x vinput-manager sendkey

Step 2: Launch vinput-manager

  • $sudo ./vinput-manager

Step 3: Launch Android

  • Add below two lines under common_options variable in start_android_qcow2.sh script.
    -device virtio-input-host-pci,evdev=/dev/input/by-id/Power-Button-vm0 \
    -device virtio-input-host-pci,evdev=/dev/input/by-id/Volume-Button-vm0 \
  • Launch CIV using start_android_qcow2.sh script.

Step 4: Use sendkey application to verify volume and power key functionality in android

  • Volume Functionality:
    ./sendkey --vm 0 --volume up => Increases volume in CIV
    ./sendkey --vm 0 --volume down => decreases volume in CIV
  • Power Functionality:
    ./sendkey --vm 0 --power 0 => Short press to trigger Suspend/Resume in CIV
    ./sendkey –vm 0 –power 5 => long press of power key for 5 seconds. Displays power options in Android.

Note:

  1. Use sendkey application only after launching CIV.
  2. To set device in to graphical mode.
    $sudo systemctl set-default graphical.target
    $sudo reboot

Follow below steps to check volume and power button functionality in CIV-GVTD

Step 1: Pre-built binaries are placed in ~/civ/scripts directory

  • $cd ~/civ/scripts
  • $chmod +x vinput-manager sendkey

Step 2: Set the device in multi-user target mode.

  • $sudo systemctl set-default multi-user.target

Step 3: Update logind.conf file with "HandlePowerKey=ignore" and reboot device

  • $sudo vim /etc/systemd/logind.conf
    [Login]
    HandlePowerKey=ignore
  • $sudo reboot

Step 4: Launch vinput-manager

  • $sudo ./vinput-manager --gvtd

Step 5:

  • Add below 3 lines under cmd field in ini file
    -device virtio-input-host-pci,evdev=/dev/input/by-id/Power-Button-vm0 \
    -device virtio-input-host-pci,evdev=/dev/input/by-id/Volume-Button-vm0 \
    -qmp unix:./qmp-vinput-sock,server,nowait \

  • eg [extra] #cmd=-monitor stdio cmd=-device virtio-input-host-pci,evdev=/dev/input/by-id/Power-Button-vm0 -device virtio-input-host-pci,evdev=/dev/input/by-id/Volume-Button-vm0 -qmp unix:./qmp-vinput-sock,server,nowait

  • Launch CIV: $sudo vm-manager -b civ-1

Step 6: Run sendkey application to verify volume and power key functionality in android

  • Volume Functionality:
    $./sendkey --vm 0 --volume up => Increases volume in CIV
    $./sendkey --vm 0 --volume down => decreases volume in CIV
  • Power Functionality:
    $./sendkey --vm 0 --power 0 => Suspend/Resume in CIV
    $./sendkey –vm 0 –power 5 => long press of power key for 5 seconds. Displays power options in android.

Steps to install g++ compiler and configure

  • By default g++ compiler version is 7.5.0 in Ubuntu 18.04 host OS.

  • In case g++ version < 7.4, install manually latest version using below mentioned commands.

  • $ sudo apt install software-properties-common

  • $ sudo apt install gcc-7 g++-7

  • $ sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 50

  • $ sudo update-alternatives --config g++

  • $ Select "g++-7"

  • command to check version
    $g++ --version

Note:
1. Execute/Run vinput-manager before lunching CIV.
2. Use sendkey application to send commands after launching CIV.
