Hi bonuzzz,

If you are happy to continue development then that would be great, you are certainly more familiar with how to drive all the tools and compile working kernels than myself. If you need any support, be it testing beta's, coding, or just a financial incentive then please let us all know. Might I suggest you post a donate link? Whilst there are relatively few active users on the Alpha forums I am sure those here would like to buy you a beer or two for your efforts!

I'm mainly interested in improving the power efficiency of this device, so for me the wishlist would be something like:

-Synapse support

-CPU/GPU clock control

-CPU voltage control

-Linaro patches for BIG.little (load balancing, packing, packing threshold tweaks)

-LCD voltage tweaks

-Disable Samsung's ridiculous touch boost which is a bit too aggressive and rapes the battery somewhat!

Would also be nice to make use of the WM5110 chipset features with "WolfsonMicro Sound Control by AndreiLu"
[Samsung Galaxy Alpha] bonuzzz:
Thanks! I do it not for money. I earn enough money fof life. It's just like a hobby.

-Synapse support -of course

-CPU/GPU clock control - with cpu i dont have any problems. But with gpu I have some thoughts. I dont have any reasons to overclock gpu, but I want to unlock 100mhz frequency and a little undervolt it. But it may will cause hangs. It needs testing.

-CPU voltage control - I think we need and gpu voltage control also

-Linaro patches for BIG.little (load balancing, packing, packing threshold tweaks) - we need testing them. I had slowness when I tried.

-LCD voltage tweaks - I havent learch this subject yet.

-Disable Samsung's ridiculous touch boost which is a bit too aggressive and rapes the battery somewhat! - i havent learn this subject too

Would also be nice to make use of the WM5110 chipset features with "WolfsonMicro Sound Control by AndreiLu - what features do you expect?

It will be interesting to port tap2wake, but i dont know how it will drain battery here.
[Samsung Galaxy Alpha] neofral:
i'm sure you have candidates for whatever testing you need :D

i personally think we don't need to overclock gpu, cpu is enough. to have 500-1500 and 800-2000 should be great.

and finally, if you keep developing the kernel - we don't need to have another kernel for our devices. yes it's true the dev community i small but seeing how many users have downloaded the TWRP (more than 1200), i think there are a lot of silent users who are keen to have good support for our device
[Samsung Galaxy Alpha] stevo_125:
comments in line.
[Samsung Galaxy Alpha] bonuzzz:
At this moment I dont fully understand the logic of working a7 and a15 cores in exynos5430. I have devices with 5420 and I see logic of switching between cores. But in exynos5430 I dont see a15 cores in idle state... I think idle state will be improve power efficiency
[Samsung Galaxy Alpha] stevo_125:
My understanding was that all the cores are "on" at all times, rather than "hot-plugging" as seen in Qualcomm designs or "Cluster-plugging" as seen in earlier Exynos chips. The task scheduler is supposed to distribute the tasks between the large and small cores depending on the computational "size" of the task. It certainly would be possible to switch the operation mode to the older "cluster plugging" a.k.a In kernel switching, but I think the HMP/GTS approach is supposed to be more efficient. What I hope is possible is to tweak the threshold at which the GTS pushes tasks to the A15's, allowing them to remain in lower power states for longer periods of time. The other thing that may help is running the A15's at a lower minimum frequency (assuming voltage scales lower). I see you've already tried this in your kernel so it would be interesting to know what effect this has on power and performance.

At this point I can only really speak in a theoretical sense, I've not done any development of this kind before but eager to learn. Any pointers or links that I can read up on would be much appreciated.

edit:

Is it possible to manipulate the A7 and A15 Vcore's independently or are they on the same rail?

[Samsung Galaxy Alpha] bonuzzz:
Yes, I expected to see hotplug policy but always-on is a little stupid:) May be it can be changed by kernel.. A15 core without any load also use power.

Is it possible to manipulate the A7 and A15 Vcore's independently or are they on the same rail? - Do you mean voltage?

ps: about testers. i dont have any beta testers unfortunately
[Samsung Galaxy Alpha] neofral:
sure you have :D

just pm me if you need anything ;)
[Samsung Galaxy Alpha] sunsettrack4:
Can anyone provide me a benchmark result of the device using this kernel, please (e.g. AnTuTu with CPU OC)?
[Samsung Galaxy Alpha] stevo_125:
Sorry, yes. Vcore = core voltage.
[Samsung Galaxy Alpha] bonuzzz:
Voltage can be controlled for any frequency for cores indepentently
[Samsung Galaxy Alpha] bonuzzz:

Custom Kernel r2, no changes

Stock Kernel

[MENTION=5623053]sunsettrack4[/MENTION]

and what? Test in real apps. I didnt write anywhere you will get +100500 point in benchmark. I'm trying to extend battery life, not to gain performance.

I think this phone is not for gaming...
[Samsung Galaxy Alpha] theendfear:
ok I tested, in first thanks in advance for your work! by my test I see this, ok the stability, finally fixed the frequencies. The system is fast and snappy, but the benchmarks are more higher with the older release (for worth that have benchs scores) old release, 53k, this release 47k.
[Samsung Galaxy Alpha] neofral:
Thank you for your work. Just flashed the zip.

I think that your kernel is much smoother in general. Apps load quicker and unlocking the phone is quicker.

I don't know why graphics are a bit lower in performance. I'm sure you will figure it out :)
[Samsung Galaxy Alpha] bonuzzz:
version 2.1

-changed some parameters in hmp and added some opmizations.

-added frandom

-added cpu frequency control through synapse

antutu 49k

[Samsung Galaxy Alpha] saxmydix:
flashed. run smooth so far ! better than 1st version. lets see the battery. thanks for your good work. now waiting for tap2unlock implement. :good:

edit : my pc seems cant detect my phone when connect to pc, and on synapes setting didnt have other option, only change frequency setting.

edit2 ; mtp working after uninstall xposed, maybe conflicting with several xposed tweak.
[Samsung Galaxy Alpha] stevo_125:
Thanks very much for this bonuzzz, I'll check it out later. It's taken me days of messing about to get all the alarms and wakelocks under control on this thing (curses Samsung!) and I wanted to do that before messing with different kernels.

I agree with your comments on benchmark scores, completely useless metric unless a huge discrepancy is present. The phone is more than capable of gaming and such if people want and a less than 5% drop in peak performance in the name of efficiency is a fair trade in my book.

So Bizarrely this crashes my browser... (version 2.1)

internet access works in other apps, but "internet" app and chrome both crash. Get force close on "internet" and "aw snap - something went wrong" on Chrome.

Wiped dalvik and cache partitions and no dice. Tried lowering the overclock, also no dice.

Suggestions?

---------- Post added at 06:05 PM ---------- Previous post was at 05:54 PM ----------

Just flashed v2 and no issue there, so something in 2.1 causing browser issue it seems.
[Samsung Galaxy Alpha] ayamgoreng:
same problem here. internet always crash with 2.1

work fine with previous 1.0 or 2.0 firmware.
[Samsung Galaxy Alpha] saxmydix:
+1
[Samsung Galaxy Alpha] gun@id:
Yes, it crash on both chrome and stock browser with r2.1 but fine with before r2.1

I'm on stock rom rooted

R2.1 very smooth btw

Thanks
[Samsung Galaxy Alpha] c0urier:
Mine does not crash, but I can't access any websites. This affects chrome, Firefox and the standard browser.

Versions prior 2.1 does not suffer from this.
[Samsung Galaxy Alpha] gun@id:
sorry my mistake, on chrome said "aw, snap" and on stock browser said "internat stop" and not happen on cm browser or puffin.

tried to set selinux to permisive and chrome work fine again
[Samsung Galaxy Alpha] S37hhh:
V2.1

I installed it last night and today after 12h usage and 1h30m screen on, I still have about 45% left. Performance is great as well.

Don't have any crashes, but have already set SElinux to permissive.
[Samsung Galaxy Alpha] neofral:
what about Viber and Whatsapp images? they weren't coming also in 2.0
[Samsung Galaxy Alpha] stevo_125:
Worked for me too. Thanks for the tip
[Samsung Galaxy Alpha] bonuzzz:
I have this bug with viber on the wife's phone. But she has another model and uses stock kernel. So I think this bug doesnt depends on kernel
[Samsung Galaxy Alpha] neofral:
i just reverted to stock and all photos came in. i had to flash the whole rom since i didn't have boot.img backup from stock. i will make a backup now and try both and keep you informed

EDIT: i just flashed r2.0 checked both Viber and Whatsapp, working OK. set the Disable SEAndroid (Beta) option in Wanam Exposed-security hacks and flashed r2.1, checked Chrome, Internet, Viber and Whatsapp - all working OK
[Samsung Galaxy Alpha] bonuzzz:
new version has been uploaded. selinux is permissive now.

[MENTION=242033]bonuzzz[/MENTION]

is your kernel support Intelliplug v3.9 & intelli-thermal v3.0?

is it right that using intelli_plug is better for battery life ?
[Samsung Galaxy Alpha] S37hhh:
What is intelliplug?
[Samsung Galaxy Alpha] MEGAX91:
Intelli_plug is a total replacement for Qualcomm's proprietary mpdecsion . intelli_plug is better for battery life ،
[Samsung Galaxy Alpha] bonuzzz:
Ths kernel is for exynos only. We dont have intelliplug for exynos..
[Samsung Galaxy Alpha] MEGAX91:
how about intelli-thermal v3.0 ?
[Samsung Galaxy Alpha] bonuzzz:
qualcomm again
[Samsung Galaxy Alpha] saxmydix:
whoever use xposed try to uninstall and reboot your phone, feel your phone fly. i think i'm use too many modules. but really disable xposed does feel the different. best kernel so far. good job.
[Samsung Galaxy Alpha] S37hhh:
I use xposed too, but really few modules.. Wanam and Gravity are the biggest I use. I don't perceive any considerable lags. Kernel is fantastic so far, Am at 54% battery left with about 1h screen on time after about 10h since charged, in which 4G data was always on.

Phone is also snappier and more responsive. Will give a try without xposed maybe in the weekend.

Cheers for OK, gj and keep it up
[Samsung Galaxy Alpha] saxmydix:
i'm also feel that same until i try to uninstall, just quick uninstall the framework to test if it feel any different. boom. phone become really smooth, no lag at all.

Rooted/Custom ROM/2.2 Kernal

Hi.

Installed the 2.2 kernal, all appears well BUT Chromecast now doesn't work. Quite a major problem for me as I use it a lot.
[Samsung Galaxy Alpha] S37hhh:
Haven't used Chromecast but have you tried uninstalling , clearing the caches and reinstalling it ? It's a bit of a hassle but give it a try as it might fix it afterwards.

This kernel is really good and worth to keep since it improves the battery life by a hefty amount.
[Samsung Galaxy Alpha] Dwibbly:

How do I know if kernal flashed correctly?

My kernal is now: 3.10.9-g16e985c, root@build #1, Fri Feb 20 01:157:37 MSK 2015

So, I think it worked. I can use Synapse now too.

What are the best values for Synapse to get good battery life but not too slow?

Thanks!

Kernel error

Hello, kernel doesn't work for me well.

After flash kernel, first that I see, that SHealth is crashed. It used few sensors, maybe some sensor driver fails. Second, I use 5GHz WiFi, and my phone can't see any 5GHz networks, only 2,4GHz.

So, I back to stock kernel.

My current kernel version: 3.10.9-3271345 dpi@SWDD5612 #1
[Samsung Galaxy Alpha] bonuzzz:
you can just change min freq to 200mhz

I dont have stock firmware now, so I cant check it. try to turn off/turn on mtp on settings--storage

maybe you use not last version. last version is 2.2

I also use 5ghz and I didnt any problems with it.

About shealth, probably you need install xposed module to get shealth working. Or wanam xposed has something for it. I dont remember. There is an issue not with kernel, but with rooting.
[Samsung Galaxy Alpha] palej:
Thanks for reply. But it seems difference in hardware.

Xposed doesn't help. Even on stock kernel, when I install Xposed Framework, SHealth crashed. Uninstall framework - reboot - everything work fine.

[Samsung Galaxy Alpha] aresbv2000:
If you want...I can test Cyanogenmod also for you. Just give me a link for download. I think undervoltage would make our phone last a bit more. I remember the Nexus 4 days where undervoltade made my phone a lot less hotter and battery improvement.

Flashed the stock kernel and everything is OK now. Thank you for your hard work mate!
[Samsung Galaxy Alpha] neofral:
unistall xposed and see what happens. i've seen all sort of strange things with xposed and only Wanam installed. i flashed a stock rom and the phone was working just as it should without any hiccups (that's for about 2 days until i gave it away)
