Haha, thanks

Then I keep DooMKernel :)
[Xperia Arc Android Development] SimonZ:
It work well

Continue to update it!
[Xperia Arc Android Development] iridaki:
The way I see it, adrianom uses FXP sources and is experimenting individually and sharing his findings with us.

Yes, this kernel is not something totally new to us, but if we encourage adrianom to work on it, who knows,

maybe we'll soon have one more great developer making breakthroughs for us humble users to enjoy.

So, if I were you, I'd think twice before being so dismissive. ;)
[Xperia Arc Android Development] Candy[MAN]:
I was not being dismissive nor had intentions in doing so. I highly promote what adrianom is doing and hope he continues to do and learn more of what he has contributed thus far. I have used many custom kernels since my x10 and now have my Arc. This kernel and Dooms are great. It was asked what the difference was and I replied with the boot screen comment. Valid answer I think. No disrespect to the developer or anyone else.

Obrigado Adrianom. Forca pra vc.
[Xperia Arc Android Development] adrianom:
Is not only the logo.... I don't change the frequency table, is the default of stock kernel, I only add new frequency for overclock (no reboot problem), the kernel have different script for optimization, he have WiFi undervolting (on test), default voltage for CPU frequency and other minor changes.

Like the name say is a StockPlus....
[Xperia Arc Android Development] adrianom:
The memory changes are not the same as DoomKernel, he change the camera dedicated RAM, I don't want change the part of the camera for a better stability of the camera.

[Xperia Arc Android Development] jimbo77:
Did you left the phone running with 3G on? I left my phone last night with data off and I only lost like 8% in 7 hours (I left it with 98%). That's a win for me haha, Now i'm using the phone with 2G Network and I still have 80% of battery after 9:30 hours, and the last 2.30 hours I have give it a light use (Played some music through PowerAmp, checked Facebook, Twitter and my Gmail Accounts)...

I'll let the phone run close to 10% percent today using only 2G network and tomorrow I'll test using 3G to see the battery comsuption.

Thanks!
[Xperia Arc Android Development] trenje:
I've flashed this kernel today and Android System is always keeping phone awake.
[Xperia Arc Android Development] iridaki:
Thanks for your reply, really, but... how can I put this... well,

I am not an idiot! :p :D

My phone had the exact same setup it had yesterday, only thing I changed was the kernel. So yeah, I can safely say I faced an odd increase in battery drain.

That sounds good and close to stock.

I have data always on, but not 3G (no coverage in my area), just 2G.

Normally I lose 1% per hour on stock kernel, but weirdly I seem to be losing way more on this one. I'll repeat the test today and see if it was an one-time-thing. ;)

Hello everybody,

For those who complained that this Kernel don't have anything new :), follows a new version with some improvements to optimize battery life, and solve the problem of users with different not default WiFi modules.

v1.6:

WiFi Power Management Tweak

Increase CPU voltage of some frequency for better stability

CPF Frequency Tweaks and Enable CPU AVS (Adaptive Voltage Scaling)

Revert: change sched_latency_ns to 600000

Revert: change sched_wakeup_granularity_ns 400000

Enable EXT3 and EXT4 Posix ACL and XATTR

Disable YAFFS ECC Check

Enable YAFFS empty lost and found folder at mount

Disable YAFFS block refreshing

Change pll2_fixup onverclock control

New compiled WiFi modules

WiFi modules included in Ramdisk

In general this version is for improve the battery life and resolve the problems of WiFi don't work because of user using not default WiFi modules (DoomKernel Modules)

Ps. For user with WiFi don't work just restart twice.

still getting wifi error. I moved from Doom's v17 to stock plus v1.6.

I still have to flash stock module.
[Xperia Arc Android Development] adrianom:
bern4d1,

Are you sure you downloaded the version 1.6? Version 1.5 still was available (I removed now).

And you did reboot twice? As mentioned above, it takes two reboot to fix the WiFi modules.
[Xperia Arc Android Development] iridaki:
Just flashed it. WiFi is working OK after second reboot!

Thanks! :)
[Xperia Arc Android Development] bern4d1:
sorry, my bad. forget to reboot it twice.

There's still significant drain when the phone is idle. I lost almost 30% overnight when I usually lost 5-7% with my setup.

[Xperia Arc Android Development] adrianom:
Strange, I'm having completely different results ...

In my tests with WiFi 100% of the time ON and screen OFF, I am having about 2% per hour.

Already with data 100% OFF (no WiFi, 3G or BT) my result is 0.5% per hour.

I am using BB .64 from LT18a (US), and my ROM is Stock .62 LT15i.

Is not to have such influence, but what is your Base Band? Which version of your ROM?

Thank you.
[Xperia Arc Android Development] adrianom:
iridaki,

Another thing I noticed in your picture, you had two major peaks of battery use, I could not understand their language, so I did not understand what they consumed so much in this period.

The rest had a normal consumption, only these two peaks is that the consumption was very large.

You could tell what was done in this period?

Thanks.
[Xperia Arc Android Development] sami55:
you made this kernal based on doomloard and fxp>>>why you did not try to make one based one jason stien‘s kernals because he is a briliant in saving battery

and his kernals is the best of battery life

keep on your great work adrianom you are amazing;)
[Xperia Arc Android Development] iridaki:
My usual setup is: Data always ON (2G only), Background Data and Autosync ON. No polling at all and the only apps that use Push are Gmail and WhatsApp.

WiFi OFF most of the time, unless I want to download something big.

My baseband is -64, stock .62 ROM LT18i.

Those peaks were because I was actually using the phone, browsing Tapatalk and tweeting. Then I went to bed and woke up to see I've lost 30%. :(

Usually, on stock kernel, when I sleep, the battery graph line is almost straight, whereas on this kernel it seems to be steadily going down for no reason.

I don't know why this happens to my phone with all your kernels, but please let me know if there's anything I can do to help you find out. BetterBatteryStats show no weird entries either.

I'll charge my phone now and repeat the testing! I'll let you know!

Thanks for all your hard work! :)
[Xperia Arc Android Development] adrianom:
Hi sami55,

Thanks for the feedback, I start using FXP and DoomKernel as basis, but now, I am making my on changes, and locking some other to.

I do not know the work of Jason Stien's, but I am take a look.
[Xperia Arc Android Development] adrianom:
You phone is Arc or Arc S? You ROM is LT18i, so I'm assuming that is Arc S, maybe that's the different, my phone is Arc.

I will check whether any change in frequency table can influence based on the processor of Arc S.

Thanks for the feedback.
[Xperia Arc Android Development] w1000i:
Can you overclock the GPU ?
[Xperia Arc Android Development] doomed151:
Just flashed v1.6, performance so far seems good. I'm about to sleep, so expect a battery report tomorrow. Let's see if it can get that almost flat battery graph that DooMKernel v18-FIX1 manages to get.
[Xperia Arc Android Development] bern4d1:
I got almost the same result with v1.6 and I'm on Arc S.

down about 30% during night.
[Xperia Arc Android Development] iridaki:
Maybe an incompatibility with Arc S devices then?

iR¡D@k!* via Tapatalk
[Xperia Arc Android Development] adrianom:
Is my suspicion, but I picked up a frequency table of a kernel made ​​specifically for the processor MSM8255T, which is the used on Arc S, and applied it on my kernel.

I'll test for a few more hours to see if work ok, if so, I submit a new version tomorrow.
[Xperia Arc Android Development] doomed151:
Min: 245 MHz

Max: 1402 MHz

Governor: interactiveX

I/O scheduler: noop

As you can see, that's nowhere close to a flat line and there's quite a bit of battery drain. Performance is good though. The same setup but with DooMKernel v18-FIX1 would get me an almost flat graph.
[Xperia Arc Android Development] adrianom:
Guys,

The frequency table that I whos test, make the Kernel very unstable, so is not worth.

I am going to try some tweak specifically for the S Arc, but I not have a Arc S, so, someone who have a Arc S could get the result of command "cat /proc/cpuinfo" on adb shell and send to me?

Thanks.

@adrianom

I can't thank you enough for this kernel. I was previously running the Latest DoomsKernel, however this one is night and day. I know Quadrant scores dont mean everything but on dooms I was only able to OC to 1.5Ghz stable, and my quadrant scores were about 2,000 range on my best runs. I tried this kernel and boy oh boy. I'm now scoring around 3,000! on my quadrant at the same speed (1.5Ghz), and my phone is cool and steady going to 1.8Ghz! @ this speed i can hit 4,000 on my quadrant scores.

I dont want to take anything away from Doom as he is a great developer and a key assest to the xda community. However some phones prefer certain kernels over the other. Some may find Dooms to work better with their phone than StockPlus. Optoins are great however and my phone preferred yours. Thanks for supplying this to the community!
[Xperia Arc Android Development] everb00b:
hows the battery life in this kernel vs doomkernel?
[Xperia Arc Android Development] ej_424:
It's decent, similar to what i experienced with dooms. About 24 hours with average use.
[Xperia Arc Android Development] adrianom:
Only you can tell ... :)

From what I've seen battery life is something that each user has a different experience.

Some users have reported that the DoomKernel have better battery life, especially with the Arc S, but other report the opposite, so the better is you test and analyze on your phone to see what is better to you.
[Xperia Arc Android Development] Candy[MAN]:
Can someone please post version 1.5? Wanna see if I get better battery life compared to v.1.6.
[Xperia Arc Android Development] adrianom:
Follow in attached as requested.
[Xperia Arc Android Development] xexijreil:
+1!

Best Kernel I've tried in battery life terms it's been Blendkernel v02 from Jason Stain, it's a pity that there's no possibility to overclock with that kernel.

I'm gonna try yours! Thx a lot for sharing your work!! Keep it up!! :D
[Xperia Arc Android Development] Candy[MAN]:
I have never tried BlendKernel before but I would like to hear your opinion in regards to battery life with this kernel compared to Blend's.
[Xperia Arc Android Development] adrianom:
New version release:

v1.7:

Enable 1200Mhz frequency

Add IO SCHEDULE BFQ

Add CM torch interface (base on Blendkernel v02 from Jason Stain)

Use disable_irq_nosync() from within irq handlers (base on Blendkernel v02 from Jason Stain)

Prepare I/O context code for BFQ

Custom tweaks in kernel config

For battery compar, follow my config and the usage that I have on this weekend using this version:

Xperia Arc LT15a

CPU Clock: 245Mhz - 1401Mhz

ROM: Stock 4.0.2.A.0.62

Baseband: 64

Data Config: WiFi 100% On, GSM Data Off, BT Off

[Xperia Arc Android Development] soumya_digi:
Are you using Quadrant booster??
[Xperia Arc Android Development] doomed151:
Yes, look at the green bar (I/O score). Normal score would be around the 1200-1500 range.

As for dev, use My Battery Drain Analyzer and see if you can get 0.8%/hr with your kernel or less. That is with mobile data off and WiFi on. Last I checked it was 1.6-1.8%/hr with your kernel during sleep. With DooMKernel I get 0.4-0.6%/hr.
[Xperia Arc Android Development] adrianom:
I/O is very high, but I am using the Market version of Quadrant:
[Xperia Arc Android Development] adrianom:
I do not know the Quadrant booster, how it works?
[Xperia Arc Android Development] tommycathh:
With baseband .56 , using ur kernel v18 my mark is around 1600 (oc 1.6Ghz)

With baseband .64, using ur kernel v18 my mark is around 3000 (oc 1.6Ghz). It's faster and smoother than the bb above. Strange and amazing! huh?

It has greater performace with bb .64. I'm using the ROM ARCONIUM 7.1

The best performance kernel that I've ever used. Still testing battery life
[Xperia Arc Android Development] adrianom:
Indeed the BB .64 is much better than .56, including battery life.

And a advice, who owns the LT15a, use the Firmware (BB + Libs) from that device, and not from LT15i. In my case the battery life was much better with the BB from LT15a.
[Xperia Arc Android Development] adrianom:
doomed151, you are right, there was a problem at all.

The problem was with the version of busybox that was being used.

I updated the version and I'll upload the new version.

Thank you.
[Xperia Arc Android Development] adrianom:
Disregard, I found how this is done, and actually one of the scripts that was copied from someone else came with the hack that changed the outcome of the Quadrant.

So disregard the value above. The real value is around 1400.
[Xperia Arc Android Development] adrianom:
New version:

v1.9:

Upgrade busybox to fix the execution of user script (init.d).

Remove some scripts that were causing problems.

Wondering if you are thinking about making a ICS kernel? Doomlord has his ICS V2 kernel, but its pretty buggy on my device and actually under performs the stock ICS beta kernel.

My device perfers your kernels for whatever reason. Hope you consider it :) Thanks for all your work to the community!
[Xperia Arc Android Development] adrianom:
I intend to do so, but I'm waiting for Sony to release the Source Code of the new version of Kernel for ICS.

The alpha version (which is available up to now) is very buggy.
[Xperia Arc Android Development] ej_424:
Super! Believe it or not, the kernel provided in ICELite Beta1 AOSP, is pretty snappy and good.
[Xperia Arc Android Development] memtronic:
Flashed today, but got stuck into boot-loop. Flashed twice - same thing.

Re-installed arconium 7.3 from scratch - boot-loop still there.

Flashed Doom's stock - boot-loop gone.

Any idea?

I want to use your kernel, but where am i mistaking?
[Xperia Arc Android Development] adrianom:
You say you used the Doom's Stock, this has no change in the kernel itself only in the ramdisk, for comparison use only the overclocked version.

About the problem, do you have any overclocking settings made ​​before flash it?

Bootloop is common on any kernel when there is a overclocking or undervolting configuration that is higher than your phone supports.

When you installed arconium 7.3, you cleaned up the data (factory reset) before?
[Xperia Arc Android Development] memtronic:
Humm... before i had Doom's kernel, but not the stock one, the other one with OC indeed, and i had my Arc S overclocked to 1.6 GHz, before installing your kernel.

Now i have Doom's stock and it's working (no overclock at all). If i try to flash your kernel it will work?

Thanks for the reply!
[Xperia Arc Android Development] adrianom:
It is likely that the overclocking configuration that existed before is still active, just do not work because your kernel now does not support.

If you used some app to configure overclocking before, uninstall it or disable to reset the configuration, and then flash the kernel again.

And after you successfully boot with the new kernel, configure the overclock again.

Ps.: this include undervolting, remove the undervolting configuration before flash the kernel.
