powerdown not working

[frank-w]

I don't know its a kernel issue,but commands powerdown,shutdown -P now and init 0 do only halt. Board stays on (green led is lighting)

tried including some kernel-options but currently without luck

[frank-w]

anything new?

it seems like Ubuntu's bug, it says we have to update systemd，I will try that.

I have tried that in debian jessie and a fresh installed debian stretch (debootstrap)...System is only halted,not powered off

[JackZengBpi]

it seems like we need to register a pm_power_off callback to handle power，or do something in machine_power_off()
http://www.wowotech.net/pm_subsystem/reboot.html

SYSCALL_DEFINE4(reboot,……) ->kernel_power_off() ->machine_power_off()
But most of machine_power_off() do nothing or just disable irq , halt system ……

[frank-w]

any progress here?

btw. power consumption does not change between running system and halted system via poweroff-command, so i assume that only the init-part of OS (stopping services, umounting filesystems, ...) is done but nothing hardware-specific

Hello frank, I don't have 6323 datasheet，and I have contacted MTK-Team to give a support，but it needs some time. I see there is no poweroff hardware operation in driver, so we need to add it by ourselves.

Any update on this issue Jack? The power button issue is a bit disconcerting

Anyone know how one can get the 6323 datasheet?

Thanks.

@drastx hello this is patch for this issue，it provided by MTK team，but I haven't tested it yet，could you have a try？

i tried it, but with the patches (imho 4-14 without documentation) switch does not work (all dsa-interfaces disappeared) in 4.14
