[MOD][KERNEL] Live OC

We all know Morfic's popular TEUV kernel which features a low maximum frequency of just 880MHz, but still shows an excellent performance. The secret sauce is the increased bus speed of 220MHz compared to the stock frequency of 200MHz. The problem is that every Nexus S behaves differently because of production tolerances for the CPU and not all devices are able to handle this increased bus speed.
Thus it would be nice to have some way for the user to individually adjust the bus speed to match the overclocking capabilities of their device. Unfortunately with TEUV the bus speed has to be defined on compilation time thus the only way would be to release different versions with different bus speeds which, frankly, would be a pain in the ass. So I implemented a way to change the bus speed on-the-fly while the device is running. In contrast to TEUV not only the bus speed for the maximum frequency but for all states is increased by the same percentage (might change this later, especially for the minimum state).
In '/sys/class/misc/liveoc' change the performance by passing a value from 100 to 120 to 'oc_value' (100 = stock performance, 120 = +20% performance; 100 is default). The bus speed and frequencies for all states will be adjusted accordingly.
I am currently running my Nexus with an increased performance +10% using the stock frequencies 100->110, 200->220, 400->440, 800->880 and 1000->1100 and after increasing the voltage for the maximum state by 25mV 30mV everything is working fine without a reboot for 24h now. The battery drain however seems to be pretty high so it might be a good idea to leave the lowest frequency state untouched. Time and your feedback will tell. Seems like the sleep frequency fix also took care of the high battery drain.
Changes to the source: http://www.pastie.org/2634833
BUGFIX:
The sleep frequency is also adjusted according to the selected OC value, so a proper sleep frequency is chosen when the device is suspended.
Bug fix: http://www.pastie.org/2635644
BUGFIX #2:
When OC value is changed, the minimum and maximum frequency limits set by the user are adjusted according to the new frequencies.
Bugfix: http://www.pastie.org/2691219
BUGFIX #3:
Made sure the bus speeds and frequencies are not changed while a frequency change is currently ongoing.
Bugfix: http://www.pastie.org/2710098
BUGFIX #4:
Instead of a spin lock (which leads to problems) we use a mutex to make sure the bus and frequencies are not changed while a frequency change is ongoing.
Bugfix: http://www.pastie.org/2710386
BUGFIX #5:
If no mutex lock can be obtained, an error value is returned to inform the caller that the frequency was not changed.
Bugfix: http://www.pastie.org/2746226
BUGFIX #6:
1. Reverting back to mutex_lock to make sure no important request like enabling/disabling further frequency changes are skipped.
2. The mutex is unlocked before the CPUfreq stats are resetted. With the above modification this seems necessary to avoid lockups when changing the OC value.
3. The frequencies and bus speed are updated only when the selected OC value actually did change.
Bugfix: http://www.pastie.org/2756640
BUGFIX #7:
Maximum OC value increased to 150.
Bugfix: http://www.pastie.org/2768535
No further patches will be published here. I have set up a git repo for all my tweaks. Each mod has its own branch to keep the tweaks cleanly separated and one can simply pull the latest patches from the corresponding branch.

Morfic's TEUV kernel was the inspiration for this mod. It is not implemented in any kernel yet.

The first bugfix.
The sleep frequency is also adjusted according to the selected OC value, so a proper sleep frequency is chosen when the device is suspended.

Pretty impressive idea and implementation.
Although I don't have this phone (hope to get one soon as it's for a great price here in Portugal), I stumbled upon this thread and I liked it very much. Keep it up!

This is eactly what I want!!!
You're my hero

very nice.
i wonder why the increased battery drain. are you still getting similar numbers in setcpu's "time in state" as you were with teuv?

My goodness! Ezekeel! You're just that excellent!

Nice idea, although I don't have a nexus S, (thanks @tapatalk for showing me this thread)

I'll need some time to wedge this in.
Check why the compile fails after adding the failed hunks (looks like possibly missapplied fuzzy hunk)
Aside i would want it to work with each kernel type, be it TEUV, TUV or T12, T13, T144 or T1544
Since that is all layed out as Kconfig options i'll have to check where to apply the code you added to stock source so it will indeed work for all the speeds, kind of as a added bonus to the current speeds.
Then i would have to shoehorn in a voltage control and OCing without voltage control is not a good idea, 1.0GHz has some obvious headroom, but the OC speeds especially will want a nudge on the voltage side if you nudge the bus/cpu/gpu across the board by x%
and with kernel.org up (not android.git.kernel.org (unless we android geeks just totally hammered it)) i would prefer to grab latest samsung source, freshen up all builds, then work on integrating this.
I could see the netarchy layout benefit from this patch as there are no Kconfig #ifdef to deal with (I'm looking at you mathkid ;P lol hah! coo <3)
Just a little timeframe setter to tune the expectations to a realistic level.
Thanks Ezekeel

Thanks to all your kind words.

Very nice.
Told you those hummingbirds are picky about their sleep freq
Now we know OCing it causes high drain instead of the typical SoD when no high enough clock is available.

Dude, ezekeel do you ever sleep or think about anything other than making our phones more powerful? How can so much utility come from one guy and why are you not employed by the government finding new and exciting ways to kill people. Imo you deserve a massive salary with a brain like yours.

[KERNEL][AOSP] LorD ClockaN (lordmodUEv8.5-CFS-VIVO-2.0)

The new kernel by LorD ClockaN for AOSP(cyanogen and MIUI) roms is here.
http://www.multiupload.com/YQTRBBDO3B
http://www.4shared.com/zip/VC9M-tPU/lordmodUEv85-CFS-VIVO-20.html
This is 8.6b3 of his DHD kernel for vivo.
Please try it and post reviews which will help him to further work on incredible s kernels.
A big thanks to LorD ClockaN for his great kernels.
Governors explained: (Thanks to LorD ClockaN )
*interactive - Instead of sampling the cpu at a specified rate, the governor will scale the cpu frequency up when coming out of idle.When the cpu comes out of idle, a timer is configured to fire within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer fires then we assume the cpu is underpowered and ramp to MAX speed.
*smartass - Is an improved version of interactive governor.
*ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
*conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
*performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
*powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
*userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
*brazilianwax - Very agresive version of smartass.
*interactiveX - Tweaked Interactive governor by Imoseyon by adding more features like suspend/wake profile.
*ondemandX - Tweaked and ported from 2.6.38 base Ondemand governor by Imoseyon by adding more features like suspend/wake profile.
P.S: This kernel is not for Sense Roms !

Installed with #146.
Boot is slow.
Bootanimation don't show correct.
A lot of lag.

this kernel for sence or cynagon or miui ?

aosp (cm7, miui). it says so on the first post.

Did a restor and reflashed the new v. 2.0 Kernel, but same problems as first time.
The strange thing is that test score with Quadrant is 3089 with both Kernels.

any changelog?

accidently im install to sence rom, this kernel accepted & working but i dont know others reflect like sms/call delay etc .... can someone test it!

Anyone else tried it? it is running fine on my miui rom. boot time was also good. couldn't find any bug in the bootanimation (maybe a slight lag in the animation).
Edit: felt a very slight lag while moving pics in the gallery.

Kernel is working fine.. Can't feel any difference between previous version and this.. But still Two Way call recording and in call audio boosts are missing.. Need the latter badly..
The only difference I feel better from Tiamat kernel is, this one does better fps in 3d and 2d animations..

I use this with CM nighlty 146 too.
booting is the same as v1.
but at governor "conservative" ,this version is much lag than V1.
For me ,V1 is faster responding than V2.
no other issue.

etc
GPL: https://github.com/NeoPhyTe-x360/i9300-S3-JB-kernel
[*] It's not compatible with 64GB exFAT sdcards (if you like to see your files you have to format your sd64 in FAT) [It's a common issue with updated kernels and proprietary modules]
Some versions go from letter A to letter D.
Letter A; Less UV, internal are more "conflictive" voltages, so letter A is a "light" uv in internals
to
Letter D: More UV, the most UV possible, agressive internal volts and -125mV GPU volts, the maximum possible without freezes in some devices.

I couldent say if the battery life is good, because i had to reflash perseus again for stability, but im very pleased with the smoothness and the general absence of lagg. I'll try the medium version now and report back...

Installation:
1. Download kernel
2. Reboot to recovery
3. Backup
*if you come from faux or tbalden please reflash your rom, you don''t need a wipe. They have some trickery with their own hotplugs so they have reomved mpdecision, so without reflashing your phone will be stuck on quad core*
4. Flash kernel
5. Reboot
*Please let it sit for ~10 mins before judging as it will need to settle down. Do not judge battery life unless you've run it through at least 3+ cycles after flashing*

DISCLAIMERS:
1) Excessive under/overvolting can cause damage to the internal parts of your phone. It can cause the phone's lifespan to deteriorate quickly so make sure you know boundaries
2) If you OC'ed/OV'ed/UV'ed and now are in a boot loop or your phone is slow, or acting weird or just died - it means your phone does not like the changes. Voltage control is for those who know what the risks are, know what they are doing and know how to fix it. Perhaps when you change these, test them for an hour or so before setting on boot
3) Any changes to the phone, including flashing the kernel itself is done at your own risk.
4) Every phone is differentt
5) Please DO NOT use any task killers (or additional init.d scripts), they DO NOT improve performance/battery. The kernel is designed to be used with stock settings: my settings and anything else can cause problems

Thanks for sharing.

Get out of here!!! I've been waiting on the kernel like forever. Thanks poondog!!

Depends what you want to do most of the time you can use trickster. But, for frequencies you'll need to use the script to cap it since o have pnpmgr enabled
Pnpmgr is HTC power and performance manager and it is responsible for boosting CPU and gou when needed. So its enabled to eliminate any stutter

I just want to set governors and clock speeds, as well as modify screen wake settings and such. Is that possible without the script?

Since you say clock speeds, you will need the script
However I am a strong believer in keeping the clock speeds stock. It has great battery already (I always last the day on one charge) and lowering the max freq say to 1.4GHz will extract a bit moer battery, maybe you will end up on 20% instead of 12% at the end of the day. If I want to underclock I will use the poewr saver option for CPU (assuming it works for you on this device, since some roms it doesn't work on) I know viperone has this working
imo, try without the underclocking and if you need it you will need to use teh script. its easy, I can walk you through it if you'd like

Any reasons to not use SMARTMAX over Ondemand?
Also I am not familiar with FIOS. I always used ROW but looking for best battery life.

Quick question for the kernel guru, I noticed the kernel mentions how it increases the gpu bandwidth, the question I'm wondering if you can elaborate what it is? I googled the feature and I only came up with hits from you!
Two words...luvvv it!

personally, i dont notice a lot of difference between different schedulers, but we had a discussion about it in the gsm thread here . as for the governors, i prefer ondemand, because (for me) it has the best combination of battery and performance, but some prefer smartmax or preservative more. you can also find some infos about that in the gps thread

Best governor,sheduler etc

Hello guys..Now how we have a lot of new kernel, in yours opinion which is best setup for performance,battery in governor, sheduler ,min&max Cpu,Gpu etc for our MI3 ? For now I use interactive,noop ,min 300 MHz and max 1,2 MHz..Gpu max 462MHz.. And that's seems ok for me..and franco kernel by audahadi

CPU:
CPU Max Freq- 1497MHz
CPU Min Freq- 300MHz
CPU Governor- conservative
Multicore Power Saving- Aggressive
Sync Threshold- 1190Mhz
Input Boost Freq- 960MHz
CPU Voltage:

CPU Hotplug:
MPDecision- ON (Stuxnet has no other hotplugs yet, and disabling hotplugs allows you to manually control which cores are active by checking boxes in CPU tab. But I didn't want to permanently switch off some cores, as it would probably affect smoothness, so decided to let MPDecision take care of it)
That's about all the Power-saving changes I made. :good:

Can you explain why have you set your Sync Threshold to 1190Mhz

Actually I can't...cuz I have no idea!
If you read the original post I linked, my aim was to increase battery life, so I just reduced all clock speeds while maintaining the default order
MaxFreq>SyncThreshold>InputFreq>MinFreq
But it gave me awesome results (again, check the link in prev post) without causing any lags, and ppl were asking for my setup, so I shared it with you guys.
Hope it helps you too :good:

okay let me explain then it used to increase the max cpu clock speed if needed, like if you've clocked your cpu at 1.5 and the cpu gets exhausted with 100% usage then the cpu will be increased to given SyncThreshold value for sometime to lower the pressure on cpu,, in simple words it should not be lower than the max cpu Freq. and preferably disabling it is a better option.. and btw your settings are just awesome phone is not over heating also and thanks.

Ah that makes a lot of sense. Thanks.
EDIT: But then why was SyncThreshold less than Max by default?

I am also wondering why people are keeping it less than default it just makes no sense.

@Gnome You are a pro kernel dev, right? Can you please explain to us (noobs :laugh what is up with the SyncThreshold value and what exactly it does?
