First off I would like to thank everyone who tested and showed support to me, Derek and Brian, second of all the original thread for our ROM is HERE << this is where you will get the most support. Expect this in ROM Manager soon. More updates to come, I am still working with Drod to figure out the recent apps in the framework. Until then please enjoy this ROM and Kernels. They are all using the BFS and undervolted as low as possible without affecting waking. THEY DO NOT affect data. Please wipe before install. Thanks and more to come soon!
BROKEN:
Nothing
Wipe first!
**************************UPDATE (04/03/11)**************************
Same version, the only thing that was changed, was the wifi module was incorrect. Same download link.
The wifi module being incorrect broke wifi, and wireless tether.
This version now also defaults to 998 MHz. Just because the kernel allows you to overclock to 1.8 GHz, does not mean you should, remember that
**************************UPDATE (04/02/11)**************************
Script fixes/changes.
New Kernels (Updated BFS Patch)
Goodbye recent apps in notification bar.
**************************UPDATE (03/31/11)**************************
v0.3 uploaded, check changelog.
Introducing: boLTEd v0.3 by Drod2169 and B16
Based off of the most recent official build of the thunderbolt, base rom from Adrynalynes debloated rom.
FIRST OFF: THANKS TO @TEAMANDIRC AND FRIENDS FOR MAKING THIS POSSIBLE. THANKS ADRYNALYNE FOR PUTTIN' OUT GOOD SH*T. THEY ****ING ROCK!
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Linear Theme by BGill55 and friends - HERE
Stock theme included
Features:
***************v0.3**************
Bye bye GPS icon (bgill55)
Bye bye AM/PM (bgill55)
Hello 1.8GHz Kernel (Pre loaded)
Few more tweaks to the guts!
***************v0.2**************
Since there are kernel issues with CWM, the kernel w/ ramdisk edits I made will be uploaded seperately as a PG05IMG.zip. Otherwise,
I virtually made it meaningless (for now)
Ads blocked by default (NOTE: This will cause issues with words w/ friends)
- To enable adds, run the script in terminal emulator (adblock -on or adblock -off enables/disables respectively)
Sense/AOSP Lockscreen option
- To switch back and forth, run the script "lockscreen" in terminal emulator (w/out quotes)
lockscreen -aosp enables aosp lockscreen (reboot to take effect) lockscreen -sense re-enables the sense lockscreen (reboot to take effect)
System Read/Write or Read/Only scripts
-To use this, run the script "sys" in terminal emulator (w/out quotes)
sys -rw mounts the system re-writeable, sys -ro mount the system read only.
VM tweaks moved to init.d due to kernel issue
Tweaked the pre-loaded sysctl.conf tweaks
ACTUALLY changed the wifi scan and vm heap size to 180/48 respectively (don't dev drunk)
***********************************
Sysctl.conf support
init.d support
Ondemand gov tweaks
VM tweaks
Fully optimized
Bash and nano added
Wifi scan interval upped to 180 for battery
VM heap size raised to 48
More I/O tweaks.
A lot more I can't think of in the current non sober state I am now.

Correct, I've been using this ROM since yesterday with the built in 1.8 ghz kernel. This is an absolute phenomenal ROM! My highest quadrant was over 2800 right after booting up.

Cool!!! gonna give it a go..

Alright I'm in, will report back shortly.
BTW thanks for the rom. Tell Drod I live in St. Pete, if he gets down this way I would surely buy him a few bruskie's for his work.
P.S. Smith, what is a good economical max clock over 1k mhz if I just want to watch movies and get the best battery life?

I hope you guys enjoy. Let me know!

Hell yeah... Gonna give it a go before I go to work tonight.

Flashed this morning, love the Rom. Runs smooth and the battery life seems better imo.
If I could make a suggestion, I love the five row app drawer a couple of the other roms have. Maybe this could be added at a later update? That and maybe a transparent app drawer. Thanks for all the work that's been put into this!

Very impressed so far (quads 1637, 1714,v1677). Everything seems to be functioning, have to wrap it up for tonight, time to go downtown and get frosty. Will hit this forum up tomorrow. Nothing like going out and depending on your phone when you've just flash a new rom/kernel. But it looks good, I'm confident. Great work, thanks again.

I LOVE this rom! Great battery life, even tho I have it oc to 1.8

OK guys we seem to be cluttering up the dev thread with idle chitchat and rubbish. Lets move all that here and clean it before the mods have to. If u have a question just ask and I am sure someone else will be running that rom ad can help.

First of all, wonderfull kernel. It rocks on stock rom LRK. Really the best kernel I've ever tested. Thank you very much g.lewarne for sharing your work with us.
But I have one question, maybe someone can explain this:
I don't really understand what does Voltgroups are used for. I mean what is the difference between groups ? Is there a better group for overclocking, such things...
Thanks

From what I recall in the original thread, Gavin explained there are three voltage groups A, B and C. There is only one on your Note, and it is dependent on the hardware of the phone. I have B which seems to be relatively stable (hope I don't jinx myself). You cannot change the voltage group.
Gavin used this information to set voltages for each CPU by gathering info from many users in each group. Some groups require higher minimum voltage than others.
If you search the HydraCore development thread and look at the first three or four posts that match you should find Gavin's very good explanation - he is a great explainer. :good:

precisely correct!
Each Note seems to contain one of 3 motherboard / cpu revisions. The kernel is able to detect which version is present, and selects the appropriate cpu voltage table for it. As Tempus said, you cannot change voltage groups, the information is there simply to aid myself in voltage adjustments.
Originally it was implemented so I could gather stability reports from many users with different versions. Since I have a Group B i was only ever able to test voltages for Group B phones. Once we knew thow the groups worked, other users were then able to experiment with Tegrak overclock is finding the lowest stable voltages, and over time i built up a pretty good spreadsheet of voltage groups / frequencies and stable minimum voltages.
I then simply increased the average minimum voltages a little (for stability) and put the tables in the kernel.
Since then, there isnt an awful lot of need for knowing the voltage groups, but its a neat little feature so i kept it
:good:
It does have perhaps one useful feature for the users, if you do as stated in my Kernel thread OP and install STD first (as this will work for everyone) you can determine the likelyhood of you being able to run the OC/UV kernel
If you have a Group A it is unlikely the OC kernel will work stably for you (but it does for some)
If you have a Group B it is highly likely that the OC kernel will work for you without stablilty issues
If you have a Group C is is almost guranteed than you can run OC without any problems
anagin, each phone is different and ymmv

Thansk for the answer.
In fact, I've searched the Hydracore thread and even the whole forum but I didn't manage to find something really clear about these volt groups.
I figure that the lower voltage the hardware needs, the better it will be for overclocking but I don't know wich group needs less or higher voltage. In fact is it worth or not to use the OC version with for example group A, or it isn't because the CPU overheat and slow down frequency by itself.
Edit: just saw you response Gavin, thanks for the explanation. So, to conclude, for common user like me, if the kernel is working without problems or FC, I don't really have to bother much about these groups

To answer your question the best governors and schedulers are the kernel defaults
OnDemand and Noop.
OnDemand is a tuned version, and for me gives the best battery life and real world performance
I would also rate governors as such
OnDemand > PegasusQ > Adaptive > Everything else
and schedulers
Noop > SIO > Deadline > Everything else

My S3 ideal setup: ROM, Kernel, Mods, Apps & Games

In 2015, Galaxy S3 is a quite old device. It was introduced in 2012, with a lot of supporters around the world. I think it is the best smartphone of Samsung ever. And in 2015, it is still a good phone with latest software update from other developers
These are my combinations of roms, kernels, mods and tweaks of my Galaxy S3 (i9300). I think it is the best combination ever, with good performance and experience. Remember that this is my own opinion, so maybe it won't appropriate with somebody. Anyway, let's get start!!!
ROM
Cyanogenmod is undoubtedly the most popular and best-performance rom ever. It is based on Stock Android, so it runs very smooth and has brilliant performance, especially in Benchmark Test. Android 5.0 Lollipop is released, then our S3 has a very good CM12 rom with latest software version. I have used this rom for 4 months, and I do not expect anything more about my phone because it runs PERFECTLY.

​ KERNEL
Since Siyah kernel is end-of-development, Boeffla Kernel is a perfect alternative. This kernel brings us a lot of things : change CPU governers, overclock CPU (up to 1600 Mhz) and GPU (640 Mhz), sound tweaks, undervolt CPU and GPU, etc. It lets us to control our devices freely and effectively. It also gives us brilliant battery performance.
Links for Boeffla Kernel i9300: http://forum.xda-developers.com/gal...rnel-boeffla-kernel-2-2-stable-27-03-t2449408
MODS
When I bought my Galaxy S3, I soon realized that is had a poor sound experience. So I looked for a sound mods that it improves my phone speaker. And fortunately, I have found a thread that had an amazing work: ACID Audio Engine. It gives me many positive improvements with i9300 sounds, and I have the best sound experience ever.

sorry for this,but,either u are not informed on whats going on these days,or just lack of knowledge.
this version you chose as your rom is EOL state,and its much worse than any rom IMO (memory leaks,stagefright not patched etc). the best rom right now is AD latest or B19 from archi as well.
kernel-wise,boeffla is EOL state again,he only update ramdisk,so this is just for campatibility still active.while things starting to end for this phone,archi wow us every single time,and archikernel latest is the most "optimized" for this phone along with his roms...
I/O sheduler-wise, deadline and noop is known to low speeds and performance crippling..best shedulers for our phone are BFQ latest,and CFQ.
ROW is better generally but not for I9300.it sucks.
You should never undervolt processor especially -75!! GPU as well. games will lag.
But this guide is,from my point of view,battery life driven.
but i would not get crazy for battery life anymore because anyways battery is fcked up so many years,especially stock.the only thing u will achieve is at best half an hour screen on time.not worth it for me
as for build prop tweaks,dont even touch it anymore,its not worth it,plus archi have better build prop tweaks and generally well made Roms.
*flies away*

My best setup is Archidroid + ArchiKernel
Cpu voltages table:
1400 1.1375V
1300 1.1V
1200 1.075V
1100 1.025V
1000 0.95V
900 0.925V
800 0.9V
700 0.875V
600 0.85V
500 0.825V
400 0.8V
300 0.8V
200 0.8V
GPU:
700 - 1.175V
600 - 1.0625V
440 - 0.9375V
300 - 0.8375V
150 - 0.7375V
CPU Governor: lulzactiveQ
CPU States: IDLE + LPA + AFTR
eMMC/SD Governor row/cfq
I think, that we can undervolt our SoC much lower, but not by setting same '-xx mV' value for all profiles, i spend about 2 hours for testing voltages on every profile. I descended to 0.8V on CPU, lower values were giving me a lot of freezes and lags. On GPU i set 0.7V (Boeffla kernel) and image went away. My ASV level is 3. I also tried it on other i9300 @ 2LVL ASV, GPU was working with same voltages. But CPU wanted extra 25mV for every profile from my table.
I also saw one more thing, ArchiKernel requies higher voltages, but it's harder to freeze phone (especially GPU) than on Boeffla.
Sorry for my bad english, i'll improve that - i promise

i wish i didnt sold my s3 :/

[Root Required] - Performance or Battery tuning Core_ctl

Intro
So this is a Guide that ive decided to make because ive found that you can get really good battery or really good performance by adjusting something called core_ctl, now Ive found that the z5's little cores NEVER turn off which in my opinion is silly so i decided to poke around and i found something called corectl and another called msm_performance.
im pretty certain this wont do any damage to your device as ive been playing with this since i got my z5 but there may be a performance hit and another note is that this SHOULD work on any S810 device or anything that has a big.little system.
Things Ive Learned
im going to note down things ive learned here that you shouldent do
- Do not Swap the big cores for the small cores using Is_big_cluster, it will cause repeat FCs and other issues.
- minimum of 1 big and 1 small core as it tends to become laggy without.
- Dont force off cores, if you want a core to turn off then use busy_up_thres or busy_down_thres
Requirements
you WILL need root and a filemanager like xplore unless you already know your way around a terminal emulator/adb
you Definately need a brain[emoji14]and just some time to read this obviously
this only works with the stock kernel or stock-ish kernels as of the moment.
Important Note
Before editing make sure everything is RW (Permission mode 744) and after editing anything be sure to change the permissions to read only (permission mode 644)
Core_ctl?
First of all these settings wont stick if you reboot so we will have to wait for Kernel Adiutor or an app alike to get updated.
anyway lets get started: you can find the parameter files in:
/sys/devices/system/cpu/cpu0/core_ctl/
(alternatively /sys/devices/system/cpu/cpu4/core_ctl/ for the big cores)
there will be 2 folders which will have this, cpu0 and cpu4. cpu0 is sort of the master core for the small cores and cpu4 is the master core for the big cores
(cpu0 to cpu3 are small)
(cpu4 to cpu7 are big)
editable files:
- busy_down_thres
- busy_up_thres
- is_big_cluster
- max_cpus
- min_cpus
Click to expand...
Click to collapse
busy_down_thres:
- Little cores
This file has a default value of "0" (looks like 0 0 0 0) (this is different for the big cores)
this means that if i change it to "25" when the cpu load dips below "25" it will then turn off cores, I recomend putting it at "40" (you dont have to change it to 40 40 40 40, you can just save it as 40)
( it seems the stock values for the big cores is fine with this)
busy_up_thres
If you havent guessed it, this does the oposite of the down_thres one, when your cpu load hits your set value then it will turn on cores, again this is defaulted to "0" for the little cores.
I have mine set to 50 for my little cores (i have left the default value for the big cores)
Is_big_cluster
this one is quite obvious but if you havent figured it out when set to "1" it then it will make the selected cluster (in this case little for example) take on heavier loads and act like the big cores
I dont recomend turning this to 1 as the little cores are little for a reason
max_cpus
this determines how many cpus within that cluster can be online at once
I recomend that you leave it at 4 as the little cores are quite weak but for the big cores you are fine to put it to 2 or even 1 if you want
min_cpus
This determines how many cpus MUST be online at once, I highly recomend that you keep 1 little core online as ive tried both with 0 minimum cores and ive had times where my device went total crazy and started lagging very bad
( you should be fine allowing 0 min_cpus for the big cores)
msm_performance
msm_performance is one of 2 (maybe more) hotplugs that the z5 uses with the stock kernel, there is msm_idle and msm_performance
there are some tweakable parameters in this so lets get started
you can find this in /sys/modules/msm_performance/parameters/
there is not much point to editing msm_performance as core_ctl is better to edit in my opinion
editable files:
- max_cpus
- num_clusters
(im pretty sure you can edit all of these but may be quite anoying to work with as they tend to reset them selves back to default)
max_cpus
so max_cpus is a global limit on how many cores can be on, it overrides what you'll find in the core_ctl but this has a habit of re-setting its self unless you change the permission mode to 644 after editing which is read only
when you open max_cpus you will see "-1:-1" this means any small or big core (e.g small:big), you can change this how ever you like, for example i recomend 4:2 or 2:2
num_clusters
this decides how many clusters you have, by default this is 2 because the snapdragon 810 has one small cluster and one big one, if you set this to 1 instead of 2 the big cores will act like any small core

Well, do you think that it would be possible to find a config as performant as stock but better for battery life ?

Works so far, so I made a small Tasker script that replace the "stock" files at every reboot with the modified ones

Nice write-up, thanks!
Though, this seems to be removed on current andro-kernel v26 so u might want to add that this is only available when running a kernel which includes this feature (like stock kernel as of now)

if you want better performance then make the big cores more aggressive when turning on and just have one small core, i tried this and it works out quite fine but gets you about the 4hrs SOT that stock gives
2 Max cores for big
1 max core for little

im pretty sure most Snapdragon 810 devices should be fine with these paths as i asked a freind with a nexus 6p to check if corectl was there and it is. im not too sure about /system/etc i usualy dont bother to look around there for stuff like this.

you may have to make some sort of script or use an app that copies modified versions for now untill an app implements the features required, i haved asked that this gets implemented into kernel adiutor but im not sure if that'll happen or not.

You can add lines inside the init.qcom.post_boot.sh files in / system / etc / in the part where it sets the sd810 (msm 8994, from line 867 onwards) Link: imgur .com/svfZ6ZE

Anyone have any battery comparisons before vs after?

Consolidated tweaks for the redmi 3

Consolidation of tweaks for redmi 3 (my usage). If you have a tweak you think is useful and want added, just comment in this thread below and I'll add it to OP when possible. Take note, if you use this thread, you are expected to have at least some working knowledge of android and the system. This is not for novices because there is the potential of messing up big time. I will not answer questions like "where can i find buildprop"or "how do I enter this code". This thread is only for discussing tweaks, research, effect/affect and performance.
Rooted users only
CPU hotplugging(only works for miui) - with this, for the most part, BIG will have only 1 CPU online when idle, and so will LITTLE
Big - add this to buildprop
Code:
ro.core_ctl_min_cpu=0
little - use terminal or add to init post boot script
Code:
echo 60 85 95 95 > /sys/devices/system/cpu/cpu4/core_ctl/busy_up_thres
echo 30 50 75 75 > /sys/devices/system/cpu/cpu4/core_ctl/busy_down_thres
I use this in conjunction with the advanced interactive tweaks for insane battery life(up to 1 hour screen on for 10%)
http://forum.xda-developers.com/mi-4i/general/guide-advanced-interactive-governor-t3280391

Not to ask to many questions.
But which software do you use to make it smooth like a baby's butt.
Currently I'm using KA and/or EX Kernel Editor, disabled thermal engine but BIG sometimes have no (tunable) governor

KA is fine. I'm using it as well. These questions are welcome, just not questions that can be answered via a general search on google or the forums.
As for your tunable governor, sometimes you might need to reload the governor in KA, meaning you change it to another governor. It does it sometimes.

Thanks for this, very helpful. My main issue with my redmi 3 is the heat (although it's not really hot, I'd rather no heat at all over higher performance).
So I've set
ro.core_ctl_min_cpu=0
ro.core_ctl_max_cpu=0
Meaning no big cores.
I've also set
echo 2 > /sys/devices/system/cpu/cpu4/core_ctl/min_cpus
So little only has 2 cores running ordinarily. I didn't use your threshold settings above, left those at default and just reduced the number of minimum cores on little.
The biggest boost to performance I've found is just setting:
echo deadline > /sys/block/mmcblk0/queue/scheduler
echo deadline > /sys/block/mmcblk1/queue/scheduler
So overall, happy with these settings. 2 min little cpus, 4 max (default) and no big cores (so doesn't get hot at all) and deadline improves performance so you don't notice the big cores being off for most uses.
FYI
Geekbench 3, single core = 724, 2400ish with (2 big enabled, 4 little, default i/o scheduler)
Geekbench 3, single core = 603, 1800ish with (0 big enabled, 4 little, deadline i/o scheduler)
Not tested the battery life yet, but I'd imagine it would be better.

But disabling all the big cores will essentially meant that you're really, REALLY crippling the phone. In all fairness, the phone handles heat better than the snapdragon 615 by quite a bit. I find that hotplugging generally helps with the heat alot. In Kernel adiutor, why not go to thermal and enable core control instead so that the native thermal engine can do its work? otherwise I would rather disable the small cores, that way you still have that little extra boost of power where you need it with the big ones. the 616 is using all a53 cores i believe, just clocked slightly differently.

True, but I'm not a heavy user in anyway, so this works perfect for me. I'd imagine others would leave the bigger cores on for the slightly better performance. The deadline scheduler gives it great performance for the non heavy multi tasking user like me.

no clue.. you could try the typical fixes first and see if they help, update supersu to beta 2.72, update busybox etc. other than that I don't have this problem so I dont know how to help with this

Up to you.. I generally leave mine lone

what version of MIUI are you guys running? I am having trouble getting the governor changes to stick. I am using MIUI EU ROM 6.5.19. I have found Lollipop to be a real headache for making system level changes.
It is not possible to get it to stick at all.
I have tried using KA and Ex kernel but it is not working properly. I tried writing the little core mod into a a script but it didn't work. I have root and TWRP. My busy box version is new. I moved KA to the system partition and I think it is working better now but still it often tells me the governor is not tune-able or gives me a blank list in the governor selection list.

echo 2 > /sys/devices/system/cpu/cpu4/core_ctl/min_cpus
Or
echo 2 > /sys/devices/system/cpu/cpu4/core_ctl/min_cpu
Or
echo 2 > /sys/devices/system/cpu/cpu4/core_ctl/min_cpu2

I got all that to work finally after plowing around for a while and updating and moving apps to the system partition and adjusting power nap. The only thing I'm still not sure about is how to set the little cpu to two on. But I have been getting about 10% per hour screen on time with 1-2 percent drain through the night. Thank you guys.

the min for little CPU doesnt seem to respect the terminal command for it, only the up threshold and down threhold.
you can try insmod the core_ctrl.ko and see if that helps

Okay, thanks, I will have to learn about that first
