I should teach myself to not write passwords in public channels :)
<

not that I ever wrote any important one, but still
<
Wizzup>
seems like my droid4 battery is unhappy since yesterday
<
Wizzup>
I took it out for a moment, but basically it shuts down at 450mAh or something
<
Wizzup>
even with leste booted, it shuts down when connected to a charger
<
Wizzup>
kinda weird

when charging I see this spamming:

<
freemangordon>
bad cable?
<
freemangordon>
loose USB port?
<
Wizzup>
led is not blinking though
<
Wizzup>
maybe it's full or something, but I kind of doubt it
<
Wizzup>
plugged in a different cable and now it's resetting I think
<
Wizzup>
yeah, was powered off
<
Wizzup>
this happened to me 4-5 times today
<
Wizzup>
which is why I had dmesg open over wifi, but I saw nothing there
<
Wizzup>
maybe I will be able to get into pstore
<
freemangordon>
could it be that battery is so bad that it goes under shutdown level?
<
Wizzup>
maybe, but it works fine without charger
<
Wizzup>
like I held it with full brightness and connected to wifi
<
Wizzup>
nothing in pstore
<
Wizzup>
it could be that the port is flaky
<
freemangordon>
buZz: who knows? did you test it?
<
buZz>
no but it looks very promising, if it cancels out the batterydraw during charging :)
mro has joined #maemo-leste
<
buZz>
i'll patch it in a local build then :)
<
freemangordon>
also, this is full of printks and whatnot
<
freemangordon>
BTW, I am playing with cpcap_adc, I may try this patch too when I am done
<
buZz>
i'm not sure cpcap_charger doesnt already do printks for changed charge states
<
buZz>
ah cool, the _adc is for the touchscreen?
<
freemangordon>
iio driver
<
freemangordon>
ADC like analog-to-digital
<
freemangordon>
various things, like battery voltage, temperature, charging current, ect
<
buZz>
ah, ok, cool
<
Wizzup>
oh, I missed his patch, it seems like it would help in some cases
<
freemangordon>
RN we can't have both battery voltage and current at the same moment
<
freemangordon>
which is one of the reasons we cannot properly estimate Ri
<
freemangordon>
IMO
<
buZz>
ahh, its doing one-shot adc but could do 'all-shots' adc ?
<
freemangordon>
it does all channels at once
<
buZz>
that would be quite the improvement yeah
<
freemangordon>
but you can read anly one at a time through sysfs
<
freemangordon>
*only
<
buZz>
hmhm, unless you use the 'uevent' file?
<
freemangordon>
iio devices does not have uevent file like battery driver, for example
<
freemangordon>
*do not
<
freemangordon>
no data in there
<
freemangordon>
for multiple samples at once IIO buffer/triggers must be implemented
<
buZz>
basically helping that driver forward 10 years? :)
<
freemangordon>
also, cpcap supports the so called "single channel", which does 4x2 over battery U/I "at once"
<
freemangordon>
4 samples over 2 channels
<
freemangordon>
curently the drivers programs the chip properly, but does not provide the data to the userspace

anyway, have to run, night!
<
Wizzup>
freemangordon: but it does like pavel's patch can help runnning mostly/only on usb power, right?
<
buZz>
from his description, i see he 'solved' the constant charge/discharge/charge/discharge when its 'full'
<
buZz>
which should save power yeah, and batterylife
<
Wizzup>
it helps with other things too
<
Wizzup>
it helps with insane upower behaviour
<
buZz>
annoyances? :D
<
Wizzup>
it's event logs gets so full
<
Wizzup>
that upower uses 100% cpu on boot for a minute
<
Wizzup>
on my device
<
buZz>
like the constant 'batteryfull.wav' you get :P
<
Wizzup>
yes, and that
<
Wizzup>
and led blinking spam
<
buZz>
:) i was really excited to see the patch anyway :)
<
buZz>
if what pavel says is right, it'll be a blessing

I just accepted his email, somehow it was stuck on the m-l list
<
Wizzup>
we need mailing list admins for it
uvos has joined #maemo-leste
<
uvos>
buZz: we discused what this patch dose a long time ago allready
<
uvos>
the problem is that android dosent use this mode and that the battery acts as a farily large cap
<
buZz>
right, but did you test it?
<
uvos>
the voltage rails on d4 are allready very noizy
<
uvos>
buZz: no this patch, but setting the registers the same
<
uvos>
this caused the voltage rails to be even more noizy
<
uvos>
i was unconfortable implementing this at the time for this reason
<
uvos>
i have no idea, but the pp noize on d4 is allready like 2 decades more than on bionic for instance
<
buZz>
well, your comfort level doesnt match mine then :D
<
uvos>
your welcome to apply this patch localy, if it causes no issues for a sufficant number of devices ill be fine with it
<
uvos>
but i dislike just pushing this to all users
<
Wizzup>
well, we need some way to not charge/discharge constantly imo
<
uvos>
we should do what andorid dose in this case
<
uvos>
turn off charging and poll until level is below 10%
<
uvos>
charge level drops by 10% or 5% or whatever (not sure what andorid uses exactly)
<
Wizzup>
does anyone want to help manage the mailing list?
<
Wizzup>
uvos: ah ok
<
buZz>
Wizzup: sure, i can do another mailman admin job
<
buZz>
i mean, i already do a couple, its not much effort to do one more :)
<
buZz>
you ment spam rejection etc?
<
Wizzup>
it's not a lot of spam really
<
Wizzup>
yeah but also message acception
<
Wizzup>
apparently our ml doesn't accept mails with to many To or Ccs
<
buZz>
oh yeah i can go through options and tweak it
<
buZz>
i'm no expert but i have some nearby :)
<
Wizzup>
I am not sure if we have full access, it's dyne run
<
Wizzup>
I've reached out before to jaromil but got no reply, so who knows
<
buZz>
ah, i'm sure it'll be fine
<
buZz>
i think nearly everything mailman just goes thruogh webinterface anyway
<
Wizzup>
any other takers?
<
Wizzup>
it's mostly about just timely approving some msgs

and will try to act timely on them if i can :)
<

freemangordon: it might have been bad contacts with the battery
<
Wizzup>
I opened the phone yesterday
<
Wizzup>
I just redid it, so maybe that was it
<
Wizzup>
uvos: btw, I asked the other day, not sure if you remembered, but did you document your changes for u3 cards somewhere?
<
Wizzup>
just dts ones, right?
