Udev power_supply rule not working with tlp

Ulilop · 2020-03-27 18:52:08

Hi everyone,

I'ven trying to setup some rules with udev:

ls /etc/udev/rules.d/ >
97-charging.rules  98-discharging.rules  99-lowbat.rules

97-charging.rules >
SUBSYSTEM=="power_supply", ATTR{status}=="Charging", RUN+="/usr/bin/nbfc set -s 100"

98-discharging.rules >
SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", RUN+="/usr/bin/nbfc set -a"

99-lowbat.rules >
SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", ATTR{capacity}=="[0-10]", RUN+="/usr/bin/systemctl hibernate"

The events are visible, and I can even test the udev rule:

devadm info --attribute-walk --path=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT0 >
  looking at device '/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT0':

Unloaded link configuration context.

The problem it's than they never get to be executed.

Looking through journal, I believe it has something to do with the fact than when the tlp rule kicks in, my rules just get ignored.

The section of journal -b with systemd-udevd entrys it's to big for this post, but this it's an stract from journal.

When the run part gets to be executed, theres a segmentation dump, (dunno if its nbfc fault or mine).

Can someone point me to what I'm doing wrong?

Thank you for the advice, it's done.

I just tested the conditions for 99-lowbat.rules and still not working.

ewaller · 2020-03-28 15:25:20

I have no way of testing nbfc. Can you run it from a shell without crashing?

Yes, when I use it on a terminal works perfectly fine. I searched for that problem and it turns out as a I/O error code, a permissions issue.
I don't really care about these two nbfc rules, they could be a nice addition, for battery performance. I will delete them for now, but maybe later they could work calling a script (the ENV could do a better job whit the I/O).

The rule that I really want to make work it's the hibernation one. And right now, still gets ignored :c
