Steps to install powerd from silo on Arale

instructions added by kgunn in frustration, good to double check on irc, but these seemed to work

Make sure to use the correct recovery img

1. First, make sure to download the recovery.img to your host machine from the correct location, as of Aug 2015 that is http://people.canonical.com/~alextu/tangxi/recovery/recovery.img

2. reboot the phone into fastboot mode by power button & vol- simultaneously from off state

3. Then flash that

host $ fastboot flash recovery recovery.img

Installing powerd on Arale

note for whatever reason, adb reboot recovery doesn't seem to allow adb, but booting into fastboot and then into recovery does

1. boot into fastboot by holding power button & vol- simultaneously, then boot into recovery by power & vol+

2. download deb from silo ppa you'd like to install onto your host

3. copy the debs to the device & install by:

host $ adb shell
device ~ # export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
device ~ # mount /system
device ~ # chroot /system /bin/bash
device root@localhost:/# touch /etc/init.d/powerd
host $ adb push /onyourhost/powerd*.deb /system/tmp
device root@localhost:/# dpkg -i /tmp/powerd*.deb
device root@localhost:/# rm /etc/init.d/powerd 
device root@localhost:/# sync
device root@localhost:/# exit
device ~ # exit
host $ adb reboot

Manual Tests

• Test that the device can automatically shutdown the screen and suspend
• Test that the device can wake up/suspend when pressing the power button
• Test that the device can wake up when receiving a call
• Test that the device can wake up when connecting/disconnecting usb charger
• See if the lab-specific screen unlock logic still works:

  bzr branch lp:ubuntu-test-cases/touch
  adb push touch/utils/target/unlock_screen.py /sbin/
  adb shell apt-get install unity8-autopilot
  adb shell 'sudo -i -u phablet bash -ic "/usr/bin/python /sbin/unlock_screen.py"'

• Test that killing a process that holds a SysPowerRequest effectively releases the wakelock. Running the following command should result in "active" not being in the list after 5 seconds (without any opened app, just unity8):

  powerd-cli active & sleep 2 && kill -9 `pidof powerd-cli`

• Unplug the usb cable and reboot the phone. It shouldn't take more than 30 seconds to reboot to the bootloader.
  • This is because if the phone takes more than 30 seconds to reboot it might mean that it's trying to suspend at the same time (bug 1452300)
