[i9300][2014/JUN/10][AOSP] Yank555.lu kernel v1.7a-beta3

[yank555]

yank555... could you please include the ability for us to be able to change the 'enable ignore unstable power and ignore margin' in power options in your next build.. pls I'd appreciate it

Sorry no, this I have answered quite a number of times

The issue is the charger / cable, to fix it, "fix" the charger / cable, which means replace it with anything other than stock Samsung.

I won't add a fix which disables a safety feature of the kernel because of flawed chargers.

Do you see also right/same battery temp when dialing via dialpad *#*#4636#*#* and selecting Battery info ?

Very strange indeed, I get a steady 30.0° exactly as you say ?! Also BMW shows 30.0° ... no clue where that's coming from ...

I will have a look if I can find anything...

EDIT :

This looks like a general 4.4 ROM flaw, as I have now flashed Temasek's V6 (full wipe, so stock kernel), shows a steady 30.0°, then I full wiped again, flashen OMNI ROM (20131115 nightly, so stock kernel), same thing...

So the kernel is reporting correctly, the ROM just won't pick it up from what I gather... That leaves not much I can do

About the battery temp thingy, just spoke to Cedric (dev of Android Tuner), he gets battery info through an API call, so it is a ROM side issue !

Eeeeek. New kernel is so sharp on the eyes!

Will this work on Temasek ROM?

If you're talking about sharpness fix, it was not in my previous kernels, and it is still not in the current ones ?!

Will this work on Temasek ROM?

Yes and no, but no need for this on Temasek's ROM, use CM11 r3p2, which is designed for Temasek's ROM.

hi everybody, after flashing cm 11 v1.6g r3p2 beta 2 on temasek v8 , es file explorer doesnt recognise my memory card anymore,(cm file manager does) i tryed also other kernels and its the same, is the a known issue or it is just me ?

On the battery temp issue (source) :

I tested this, and I can confirm this happens on ALL 4.4 ROMs, both Temasek's with stock kernel (full wipe) as well as OMNI with its stock kernel.

Checked using *#*#4636#*#* in dialer and looking into battery info.

Kernel does report battery temp correctly in /sys/class/power_supply/battery/temp . So it looks like a ROM side issue.



That is CPU temp, not battery temp.

V9 introduced android 4.4 way of reading battery.

Does it mean V9 will report battery temperature correctly? Because I'm currently using this version and it still displays a steady 30°C.

Also, just wanted to know whether it may cause any issues or I can simply ignore the problem.

It's just a wrong display, so no need to worry. From what I gather, Temasek should have fixed the readings in V9 ...

Here's the commit comment :

[libhealthd] Proper battery paths

* 4.4 introduces a new daemon, healthd, that handles battery status
- resides in: /system/core/healthd
- BatteryMonitor.cpp iterates through all the *directories* under
/sys/class/power_supply looking for a file called 'type'
- if the type == Battery, it assumes this is the location for the
battery stats for the device. Only the first directory that matches
this criteria is used.
- on msm8660/d2/jf/s2 kernels, this search results in:
/sys/class/power_supply/fuelgauge.
- To determine capacity, healthd looks at the contents of the
'capacity' file under this discovered base path. This results
in /sys/class/power_supply/fuelgauge/capacity on msm8660/d2/jf/s2
kernels.
- Unfortunately, this is the wrong path. The capacity file at this
location returns a large negative number.
- Other paths like status, voltage_now, and present are also
incorrectly determined.
* For comparison, in 4.3 battery statistics gathering was handled by
frameworks/base/services/jni/com_android_server_BatteryService.cpp
- BatteryService does a similar search for a file called 'type' with
the contents of 'Battery'
- But the search logic is different here: it takes the *last* path that
matches the criteria.
- This results in the correct /sys/class/power_supply/battery
* This patch overrides the discovery mechanism for battery status completely.
