provide common source for a overall battery time information

Rejected Information


In the past we used powersaved to get battery information. Powersaved provided information about each battery but also about all batteries. There was a overall battery object which e.g. provided remaining time information for all batteries in the system (of one type).

Now we use HAL to collect these information. Unfortunately there is no such overall battery object to calculate the full remaining time in multibattery machines. HAL has no such object like powersaved.

AFAIK g-p-m calculates it own remaining time, but KPowersave only use the info from HAL. Because of this KPowersave show no overall remaining time. IMO it's no option to do all the magic like g-p-m in KPowersave. There should be a common place to do this and provide the same information for all applications (KDE/GNOME/....). It could be HAL or a new powermanagement daemon (like powersaved) if DeviceKit is comming.

This feature is usefull if all applications that show battery information would use it.
Jared, who can tell us if g-p-m would accept that solution?


We should also enhance this feature a bit. Hal should also serve individual and overall power consumption. This is needed for feature:

#302446: Power consumption gauge

We need to make sure that any changes are made in time for g-p-m to take advantage of the changes in time for SLE11. Richard Hughes is the upstream maintainer.

I forgot to mention another feature that should make use of this:

#304716: Support multiple battery indication

Danny, please contact Richard.
Since you need that feature for kpowersave anyway, let's do it.

I assume we are going to reject this?
