Fards,

Are you going to upload your kj6 patched kernel? I flashed this kernel on the kk1 rom and it is running great. Looking forward to trying your kernel too.

If I can work out why the simcard isn't working...

trying a build on unedited git clone to check.

{edit} nope, not playing at all.

river source, can you just check your git push please? in case something went wrong.
I'll start digging through mine.

I'll be following the work you guys are doing very closely... Very much appreciated.

Do you have WLAN enabled? Do you use the Battery Monitor Widget? Both can cause high Android OS Usage.

Are you sure about wifi? In the battery help Samsung says that if you use it instead of 3G you battery consumption will be lower.

I am also using Battery Monitor Widget, do you suggest to remove it? It would be such a pity if a monitoring app for battery is draining it!

wifi is a much bigger battery drain here, than cell, but can you keep on topic

StNickZA · Nov 15, 2011

Today was better, battery-wise; about 4% per hour. Granted, my usage was low.

The difference today was that I set the Wifi sleep policy to "when screen is off".

I believe that the signal strength plays a large part in how badly wifi drains the battery, and in many cases, with a strong Wifi signal, one may find that it uses lower consumption than 3G. At my office, I have particularly bad Wifi reception where I sit, which could explain a lot.

Nevertheless, Android OS is still the highest consumer of my battery according to the stats, which is not what I expected from a 2.6.35.14 kernel.

I will perform a clean checkout and test.

RiverSource · Nov 15, 2011

A Clean Checkout works fine for me.

I have kj4 rom. I have just flashed kj6 modem, and this kernel, ill report back on the battery useage, before i had 15-20% android system os consumption and bad battery life. Im very interested in the interactive governor it is much faster too!

nope not playing here, getting unknown baseband yet your kernel works fine

the Makefile suggests you're using codesourcery toolchain, I'll check that one as I've used linaro 4.6 and . prebuilt 4.4.0 (and 4.4.3)
(btw your script and Makefile have permalinks)

I flashed the new kernel but didn't notice any difference straight away. I watched a few TV episodes before going to sleep and after waking up, battery usage had hardly dropped over the night. After fiddling with the device, battery usage has risen to previous 'Android OS' bug usage.

I left Wifi on overnight too [as I did with my S2], so I don't believe this is causing the drain. Android OS has now risen in the battery usage stats... this bug should've been ironed out before Samsung released the Gingerbread firmware.

Hi, I'm interested in learning about kernel and ROM building - can anyone suggest a good beginners resource?

I have plenty of experience programming, a little *nix experience, but i don't have a Linux installation - can the development and builds be done in windows?

No. You need Linux, even if its in a vm..

Try the android source page for starts, or have a search on here, there's quite a few tutorials

Kernels build with Codesourcery didn't work for me, they don't boot. Even the boot animation does not appear. I'm not sure about the reason, maybe the ABI.

Linaro 4.6 ends up in a Boot Loop after boot animation. Linaro 4.5 is the best. Android gcc 4.4.0 and 4.4.3 work also, but CF bench decreases about 2000 points (Linaro optimizes better).

It is. Even Android OS consumption grows rapidly if Wifi is on. Depp Sleep ratio also sinks considerable. I don't know why, but Wifi is a battery killer on the Note.

bcm4330 is it same chip as in sgs2 ?

maybe worth checking the bcm bin firmwares from all the current releases?

for anyone building of your github..

they need to add initramfs/lib/modules/ folder manually if using the build.sh

hth

fards · Nov 16, 2011

prebuilt linaro gcc 4.5 building fine btw

spekesel · Nov 16, 2011

Over 1 day on the battery.

OK, as I said before, good battery life now.

Check this out, this is my normal usage (I don't phone with this very much). more note taking and doodling during meetings

Still got 13% left.

fards · Nov 16, 2011

hope riversource doesn't mind.

Here's a test kernel with TUN and CIFS as modules and interactive as default

I can't test either tun or cifs.,

tun was built in, but didn't seem to be loading for some people.
extract to sdcard and install with CWM

now on to seeing what can do to push this a bit more..

Nice to see you merged the KJ6 diffs in riversource

tempted to try the Glonass gps option

http://en.wikipedia.org/wiki/GLONASS

built, and booted, need to test it, but got 3d fix accurate to 16m inside the concrete roof here at work in under 1 minute (wifi fix immediately)

do get a downloading icon on the status bar with the glonass (but that could just be wifi location)..

I thought it was built in.
