http://bugzilla.opensuse.org/show_bug.cgi?id=1190563 Bug ID: 1190563 Summary: Problems with acpi_call package Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: popov895@ukr.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I'm using a ThinkPad which supports advanced battery management via TLP, like charging thresholds and recalibration. To enable these features, I followed the instructions in the TLP docs (https://linrunner.de/tlp/installation/opensuse.html) and installed packages tlp, tlp-rdw and acpi_call (to install acpi_call I added repository https://download.opensuse.org/repositories/Base:System/openSUSE_Tumbleweed/B...). But after that `sudo tlp-stat -b` reported me that acpi_call is not installed:

$ sudo tlp-stat -b --- TLP 1.3.1 --------------------------------------------

+++ Battery Features: Charge Thresholds and Recalibrate natacpi = active (data, thresholds) tpacpi-bat = inactive (kernel module 'acpi_call' not installed) tp-smapi = inactive (ThinkPad not supported)

+++ ThinkPad Battery Status: BAT0 /sys/class/power_supply/BAT0/manufacturer = LGC /sys/class/power_supply/BAT0/model_name = 01AV445 /sys/class/power_supply/BAT0/cycle_count = 250 /sys/class/power_supply/BAT0/energy_full_design = 45000 [mWh] /sys/class/power_supply/BAT0/energy_full = 38140 [mWh] /sys/class/power_supply/BAT0/energy_now = 38140 [mWh] /sys/class/power_supply/BAT0/power_now = 0 [mW] /sys/class/power_supply/BAT0/status = Full

/sys/class/power_supply/BAT0/charge_start_threshold = 65 [%] /sys/class/power_supply/BAT0/charge_stop_threshold = 65 [%]

Charge = 100.0 [%] Capacity = 84.8 [%]

+++ Recommendations * Install acpi_call kernel module for ThinkPad battery recalibration

Also `sudo modprobe acpi_call` reported me that acpi_call kernel module was not found:

$ sudo modprobe acpi_call modprobe: FATAL: Module acpi_call not found in directory /lib/modules/5.14.1-1-default

After that, using `rpm -ql acpi_call`, I found that acpi_call doesn't install the kernel module:

$ rpm -ql acpi_call /usr/libexec/modules-load.d /usr/libexec/modules-load.d/acpi_call.conf /usr/share/doc/packages/acpi_call /usr/share/doc/packages/acpi_call/README.md

Further, after some researching, I found that in addition to acpi_call I need to install acpi_call-kmp-default package, which actually installs the required kernel module:

$ rpm -ql acpi_call /lib/modules/5.14.1-1-default /lib/modules/5.14.1-1-default/updates /lib/modules/5.14.1-1-default/updates/acpi_call.ko

But now the output of `sudo tlp-stat -b` looks like this:

$ sudo tlp-stat -b /usr/share/tlp/func.d/35-tlp-func-batt: line 25: 6070 Killed $TPACPIBAT -g FD 1 > /dev/null 2>&1 --- TLP 1.3.1 --------------------------------------------

/usr/share/tlp/func.d/35-tlp-func-batt: line 25: 6263 Killed $TPACPIBAT -g FD 1 > /dev/null 2>&1

As you can see, I am getting error "/usr/share/tlp/func.d/35-tlp-func-batt: line 25: xxxx Killed $TPACPIBAT -g FD 1 > /dev/null 2>&1". The TLP developer told me that I should use a recent version of acpi_call (https://github.com/linrunner/TLP/issues/571#issuecomment-920318813). Actually, I guess that the following should be done to fix this issue: 1. Update acpi_call to the recent version 2. Install the acpi_call-kmp-default package as a dependency of the acpi_call package System information
