Actdead: Charging when switched off is broken

rinigus commented 3 years ago

switch the phone off
attach USB for charging
phone will boot

After boot,

no SFOS charging animation is shown
screen is black, but stays on
on unplugging cable, it does not shut down
had to force reboot (power+volume up) as long power press didn't do it

After applying latest Seine patches, phone reboots when entering actdead mode. Would have to investigate

-- Reboot --

Spent some time on it, cannot figure out what is wrong, unfortunately.

Same log as above when it reboots by itself. Currently, configs were updated, but that didn't help. Sometimes it boots and shows (backlit) black screen

On AOSP10, my build:

On startup, charging battery is shown and screen goes black (no backlight)

when starting using USB connected to PC - phone starts and reboots.
when starting on charger, it looks like it hangs. After screen going black and removing cable, I cannot start the phone except hard reset (vol up-power combo).

Stock works as it should

There are differences in SFOS and Android charger boot.

Looks like PC reboot in SFOS can be avoided by setting in /init.rc:

on charger
    class_stop charger
    trigger late-init

That would result in phone just hanging and only force reboot brings it out.

Looks like the issue with actdead can be resolved. For that, AOSP bits need to be patched as well as SFOS script skipped.

Actdead mode in SFOS switches Android init from 'charger' to 'late-init'. However, the switch is probably happening after some other Android init scripts already configured USB and maybe few other things. So, I had to disable all on charger startup services in system init*.rc. The corresponding patch will be generated as a part of the fix.

In addition, running /usr/lib/startup/limit-cpu hangs the device with "/usr/lib/startup/limit-cpu: line 18: echo: write error: Invalid argument" as an output. To avoid this script, I had to disable limit-cpu.service in actdead.target.wants.

Will test now the corresponding changes in a new image
