Hi Gerald, Le Tuesday 05 May 2015 à 16:20 +0200, Gerald Pfeifer a écrit :
I have a hunc "this is a feature, not a bug" ;-), but with the update to kernel 4.0, /proc/acpi/battery/BAT* is gone.
Is there a way (config option we could enable) to get this back?
It was removed on purpose by:

If not, how can I best re-implement something like the little script below (which works for more than one battery in case you are wondering about the complexity):
#!/bin/bash
sum() { s=0; while read l; do i=`echo $l | cut -d' ' -f1` printf "%5s " "$i" s=$(($s+$i)) done printf " = %s\n" "$s" }
for v in "design capacity" "last full capacity" "remaining capacity" "rate"; do printf "%18s = " "$v" cat /proc/acpi/battery/BAT*/* | grep "$v:" | cut -d: -f2 | sum done
The following should work except for the "rate" which isn't mentioned in the sysfs interface. I seem to understand that this isn't considered a property of the battery so you have to derive it yourself from the the other numbers over an arbitrary period. #!/bin/bash sum() { s=0; while read l; do i=`echo $l | cut -d' ' -f1` i=$(($i/1000)) printf "%5s " "$i" s=$(($s+$i)) done printf " = %s\n" "$s" } for v in "energy_full_design" "energy_full" "energy_now"; do printf "%18s = " "$v" cat /sys/class/power_supply/BAT*/$v | sum done Hope that helps, -- Jean Delvare SUSE L3 Support -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
