[Kernel] Tigers Blood v3.22 Voodoo Lagfix, Sound, Color, BLN, OC/UV[03/31/11]

As a learning experience, I decided to give kernel developing a try. Tigers Blood is the result. I wanted to make a kernel with some OC/UV capabilities, but yet stable enough for the everyday user. I took a minimalistic approach and by default, the kernel is at stock clocks and voltages and will clock to 1.2 Ghz.
Includes :
Voodoo Sound v7
Voodoo Color
Vodoo Lagfix with modified Clockwork Recovery
BLN (Neldar's free version of "BLN Control" is included - Please donate to Neldar or buy the full version in the Market if you like his work - Full version allows blinking backlights)
CIFS ("Mount Manager" in the Market will get your network drives mounted)
TinyRCU
339 MB Ram Hack
OC/UV capable to 1.2 Ghz (Stock clock and voltages out of the box)
FPS Cap Lifted (No FPS Hack Version Available)
jhash3
v2.2 Additions :
FPS Cap lifted (No FPS Hack Version Available)
341 MB Memory
Voodoo Sound v5
v3 Additions :
339 MB Memory to correct FFC issues (Will work to get increased)
Voodoo Sound 6
Some VM tweaks to improve responsiveness - Some parts used found here
jhash3 - Smoothness and responsiveness Found Here
Some other tweaks I can't think of right now - Quads a bit higher - more to come
v3.1 Additions :
Battery drain issue fixed
ext4 patch found here
Some debugging removed
3.2 Additions :
Voodoo Sound v7
Fixed Lockscreen Issue
More Battery Improvements
3.22 Fix:
Major Compile bug causing bad battery drain
For installation : Flash from Red Clockwork only. If you have a ULF kernel, go back to stock w voodoo first before flashing this kernel. No need to disable Voodoo lagfix before flashing.
For OC : Download Voltage Control from Market. If you have a previous version of Voltage Control, uninstall first and reinstall from Market. For some reason the voltages will show incorrect readings if not uninstalled first. Once installed, open app and in the "Limit clock to" dropdown, select 1200 Mhz if you want OC.
---Once you have it set, hit menu then "Apply for now". This is a temporary setting that allows you to test stability. On reboot, the setting will revert. If you are happy with it's stability, the go back into Voltage Control and hit menu and "Set on boot", which locks in the setting.
For UV : Also use Voltage Control app to set voltages. From testing, several of us have found that the less voltage steps, the better. For instance, Skitz has found that not touching 100 or 200 Mhz, but dropping 400 Mhz by 100 mV, then leaving 800 Mhz and 1000 Mhz alone, but dropping 1200 Mhz by 25 mV worked well. That gave him three voltage steps 950 mV for 100, 200, and 400Mhz, 1200 mV for 800 Mhz, and 1275 for 1000 and 1200 Mhz.
I used : for 100 and 200 Mhz -50 for 900mV, for 400 Mhz -50 for 1050, I left 800 alone at 1200 Mv, Dropped 1000 Mhz -75 to 1200 mV and left 1200 at 1300mV
---If you find a setting that works well, please post so others may get an idea of what works best.
---Once you have it set, hit menu then "Apply for now". This is a temporary setting that allows you to test stability. On reboot, the setting will revert. If you are happy with it's stability, the go back into Voltage Control and hit menu and "Set on boot", which locks in the setting.
Note : Many phones simply cannot handle OC or UV or to not as extreme as some. Play with it a little and find what works for you. The above settings are just a set that works for a few people.
Use at your own risk. Kernel seems very stable to those who have tested, but bad things can happen when you mess with your phone. Make backups before flashing.
If using profiles in SetCPU, do not set the minimum Max frequency below 800 Mhz.
I would like to give special thanks to :
ttabbal for pointing me in the right direction on several things
morfic for also giving me some pointers
Jocelyn for even more pointers
supercurio for all of the hard work he has put into everything Voodoo
Skitz for testing voltages and stability
jdiddyub and secretseven for the awesome boot image and also testing
KennyPowers and SeRi testing
Neldar BLN and BLN Control
Paul McKenny TinyRCU
Raspdeep for the baseline for OC/UV
harcore for ideas on VM tweaks
cmenard for some tips
Anyone else that I have missed, I am truly sorry and just slap me with a large trout.

This is an awesome kernel!
Thanks grendel.
Where is your donate button?

Just flashed this new kernel. I mean Duh, winning!
I feel the warlock energy. Now to reduce my voltage...
Update : The uv settings mentioned caused a lockup for me. Does anyone have the list of stock galaxy s voltages? I remember it being posted in another thread at some point...

The kernel is set to stock voltages by default. If you did not tell it to "Set on boot", then on reboot it should go back to stock. If you did tell it to set on boot, then you can Select menu--Revert settings and it should take you back to stock.
The stock voltages are :
1000 =1275 mV
800 = 1200 mV
400 = 1050 mV
200 = 950 mV
100 = 950 mV

Very nice kernel. Thanks man. Running great

uncap the gpu, I think that's about the only thing missing.. overall great kernel!
edit: only seeing 333 mb ram instead if 341 mb

Awesome. This is perfect. Thank you.

Grendel, best not to disappointttt!!! WHHOOOTTTT!!!

I have Bionix V 1.3 which came with the pre-installed Overstocked Kernel. How do I know if it is a ULF Kernel?

Fantastic work sir....next time im in the mood to recondition my battery i will DEFINITELY be flashing this. thanks for the new content!

Overstock is not a ULF kernel, so you should be fine.

Red recovery means you have Voodoo, not necessarily ULF. Dead Horse is ULF, most others are Voodoo only, except maybe some kernels from a few months back

This kernel is insane! It was real fast out of the box, even before the oc. I have been waiting for a kernel like the old school jac kernel. You sir, are the man.

[POLL] Overclocking, How far does you galaxy Go and S stay stable? without rebooting

How far is your Galaxy s stable?
mine just hits the 1.1GHZ, beyond that only crashes no matter which voltage i Use. please Use the poll so we have a good picture of what the average galaxy s is capable of..
also comment which version of SGS you are using and 8gb/ 16 Gb etc..

i9000m
PS this thread should be moved to General

had mine at 1.54ghz running MIUI with tk glitch kernel.
was amazingly fast, but my phone got hot quick, i dont like OC'ing i feel it may do more harm than good in the long run.
others may and will disagree but thats my opinion on it

Mine with 1.3GHz OC and some Undervolt is perfectly stable.....

Agree with the chef ...
Although I can overclock to 1540MHz it does get hot and Im sure it will do damage in time ..
1300MHz is a great overclock ...
It will be interesting to see what my SGS 2 can be safely overclocked to

1.2 GHz seems ok for me - with UV
Doesn't really get hot.

Running mine @ 1440 MHz with MIUI but i think I can go higher if I want . I have the 8 GB version

1.3 and very stable and with great performance both q score caffiene mark and in daily use

Which voltage are you using?
Mine seems to freeze on voltages above the 1.3V,
above the 1.2 GHZ always freezes. I,m using darkeys 9.5 Rom.
someone some advice which rom is the best for OC, (just for benchmarking) for once.

Mine can handle up to 1.3-1.4ghz

Im getting stable speeds of 1.7ghz. Im on watercooling though..
Sent from my GT-I9000 using XDA Premium App

1.4ghz is my max for full stability. 1.5ghz works fine (no reboots), but the CPU occasionally gives an invalid result during calculations, e.g. during benchmarks like linpack, results can sometimes be inaccurate; 1.44ghz also seemed to work, but I picked 1.4ghz max for longevity/reliability.
UV Values are:
100mhz - 200mV UV (750mV)
200mhz - 150mV UV (800mV)
400mhz - 100mV UV (950mV)
800mhz - 75mV UV (1125mV)
1ghz - 50mV UV (1200mV)
1.2ghz - 50mV UV (1300mV)
1.3ghz - 0mv UV (1400mV)
1.4ghz - 50mV UV (1400mV)
Max UV were found by starting from 100mhz Max frequency, decreasing UV until stable for 5 minutes of software decoding of 720p MKV, and then increasing Max frequency one step. Occasionally the previous step UV needed to be decreased by 25mV to obtain a stability at the next frequency step.

I can run my SGS stable at 1540 MHz with glitch kernel in MIUI 1.5.20 ROM.
Total stability in a 48 hours stress test.
Enviado desde mi GT-I9000 usando XDA Premium App

Mine is stable at 1.5 Ghz with a 200mv undervolt, but only if I select it as a single frequency.
For multiple frequencies, I was stable at 1.4Ghz on an earlier kernel, but it's slightly unstable now... I'll probably try tweaking the governor.
I'm on a i9000m using tk-glitch's V9D-VC and CM7 #11 build.
By the way, shouldn't this thread be in general?

I am on MIUI v3 and CM7_SGSMTD_platypus-kernel_20110522_r0_quorra-prer11_test4-r2 kernel.
I don't use undervolt settings and 1.2 Ghz is fine for me; above values generally don't work stable.
By the way, 1.2 ghz is almost enough for all games and operations, I did not run into that pushing apps for high oc's.
Regards.

1.44GHz, extremely smooth and stable!

Never seen an option to go above 1.54, but 1.54 works flawlessly so I've chosen 1.5 in the poll. (16gb i9000)

1.3-1.4 GHz tkglitch kernel Miui v3
Sent from my GT-I9000 using XDA Premium App

It's not the ROm it's the KERNEL who can oc, i adviise using XAN, hardcore kernels in 2.2. or gto's ginger kernel at 2.3 they are stable and 1280 i guess it's the limit not to warm up
But a questin what send me an undervoltage config, to 1300 if the gpu games work for someone at 1300mhz

[*] 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 had the most fluid and lagg- free experience with your kernel, only problem is the phone would freeze every now and than.. I tryed the semi extreme version on Anono Rom v19. 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...

Could you post pictures for stwaeks showing how can i put kernel confgratin

Will do but it may be done in the next month, Thanks for your suggestion.

First of all THANK YOU for spending your time on this and sharing your result with us!
Just flashed the kernel! Good news...nothing is bricked
CPU Spy Plus indeed shows 1836 Mhz used! I did´t do anything for that.
You might re-think this. Using 1512Mhz instead by default and let the users choose that high speed CPU mode themselves as it may not be stable on all devices.
That 324Mhz added is a huge step...there is no step in between possible?
What about voltages. Did you modify anything? Is the voltage raised to achieve the high cpu frequency? Please post some more information about what happens here...
In fact I´m just running Antutu to see general stability on my device.
VERY BAD score. Before your kenel there were 20300 points. Now with OC only 19746.
=====================================================================
EDIT: Just recognized.... several questions are being answered by Antutu CPU Master.
1512 IS USED by default!
1620Mhz and 1728 Mhz are there to choose and of course finally the 1836Mhz.
Scaling is interactive by default (changed to my fav ondemand)
I/O Scheduler is cfq by default (changed to my fav noop)
Antutu Score @ 1836Mhz: 16077Mhz ???
Lower than without OC? Needs retesting (14230 point when setting max to 1836Mhz and Min to 1512Mhz(!!!???)...maybe the benchmark is wrong...Will give it some time to see if I myself feel a speedup.
After Restart Antutu Score ends up @ 19761 points...not bad. but clearyl not enough looking at the massice OC done. REBOOT! Tab just rebooted! So 1836Mhz is not stable at mine! Trying 1728Mhz now instead.
18139 points....this kernel lacks some serious power if we can believe the scores of antutu. This is a V0.1 so nothing to worry too soon. You´ll make it find it´s power
Switched back to kernel from pulser_g2 (http://forum.xda-developers.com/showthread.php?t=2444452) and 19908 points without any OC! You may look into it.
But please answer the other questiones I wasn´t able to clear myself.
Greetings

Sorry for my late,
I've tested Antutu with 1512MHz and 1836MHz. For my Tablet Z, I got ~20000 (1512MHz) and ~23000 (1836MHz).
My Tablet Z has fast binning CPU. Can you please tell me which binning your CPU is? Thank you!

hard to tell...did taht thing in Terminal emulator....it tells me "1".
Not fast or slow or anything...

Switched back to kernel from pulser_g2 (http://forum.xda-developers.com/showthread.php?t=2444452) and 19908 points without any OC! You may look into it.
But please answer the other questiones I wasn´t able to clear myself.
Greetings

Don´t know....after the disastrous performance of the first release I of course switched back to stock.
Now there is the new version which does not cut performance in stock mode.
I´ll OC now to 1728 Mhz and see how it performs with that....battery life is not really good with stock so if you are already asking...FORGET ABOUT alternative kernels not optimized for battery.
That is why I don´t use CM oder AOKP on my Note1. I just eats the battery for breakfast....
OK OC just seemed to scale...20300 points (ca. 19300 at stock speed)...trying 1836 Mhz now.
17389 points....clear drawback....possibly because my device seems to have a bad CPU from what I´ve learned....wanted to use the 17xx Mhz anyway....oops....device just rebooted....my device just isn´t capable of the max cpu setting. :crying:
Anyway the working 1728 Mhz working is great news!
Will give it further testing...

I have two APQ8064 devices, Nexus 4 and Tablet Z. Nexus 4 is 0 (slow), it will reboot sometimes even on [email protected], the Antutu would force close and red light of death would happen if you ignore it and attempt to run again. While my Tablet Z is 2 (fast), this can run at [email protected] and got 23XXX in Antutu.
I don't have an idea which frequency can the 1 (nominal) APQ8064 clock at, but I think [email protected] will be OK. Also, keep eyes on the CPU float-point section in Antutu. At 1512Mhz, it is around 2000. At 1836MHz, it is around 2200. If this drop lower, just pull up the voltage BUT NOT TOO MUCH!!!

Raising voltage is not an option to me. But anyway...which app do you use for that on tablet Z?
What App do you use for cou control?
I use No-frills. Do you change "interactive" and or "cfq"?
Numbers right after reboot and stopping some unused apps...just stock apps running...
2729 / 930 / 1112 / 1050 / 511 / 927 / 1436 / 5278 / 696 / 600
>>> 15269 points @ stock !!!
switching back to stock....

I would like to know this as well. Also, how do you check to see which processor you have? (0,1,2; slow, nominal, fast)

What is the terminal command to find out? I also considered custom retelling to add some processing oomph. On a per app basis, but reading this... Stock SGP311 on 4.2.2 is chugging fine just north of 20000 points on Antutu. Can we compare Versions? Mine is 3.3.1. I faintly recall reading they mixed up some benchmarking internals because some corporations found loopholes to cheat / inflate scores on new to market devices, maybe that's the discrepancy there?
Another wild thought, could there maybe be, aside from different CPU Models, different kinds of cache / memory scattered through the devices? Would not be the first time a sub par. Cache/Memory bottleneck severely strangled a nominally and factually quicker CPU into much lower overall results. Much depends on weighting within Antutu

Man, what happened with your kernel? We need some stock kernels for 4.3

Nexus 5 Undervolt tables

Guys I created this thread to compare our undervolt tables and be able to find stable values ​​used in the various PVS. My Nexus 5 is PVS 3 with Franco kernel R25.
My tables are as follows:
-75 global
300 MHz
650mV
422 MHz
675mV
652 MHz
700 mV

I have a PVS 3 Nexus 5 too, and I can barely undervolt it. Undervolting it -50 globally would reboot the phone during Antutu benchmark. I tried doing -50 at just 300 MHz, and ran stability test with the phone locked in at the frequency. It crashed after 30 minutes. I think I am going to leave the voltages alone, as my phone seems to already be running at the lowest voltages that it is stable at. I can run it at -25 mV globally, but why bother.

I have done many tests as you can see above, I had to increase the voltages. Now I had no reboot with the entire charge cycle, unfortunately not all CPUs are equal then my values ​​are not suitable for everyone.

I also started undervolting with the values of the OP and it's working pretty good with my phone.
-75 globally and 300mhz starting at 650 with the next 5 steps also less then -75. So far I had no crash in several benchmarks and no crash after 2 hours stress test at 300mhz and 422mhz.
My CPU is PVS 1 so I wonder a bit about it^^

There's an undervolting thread here if anyone's interested: http://forum.xda-developers.com/showthread.php?t=2537000
Although it hasn't been posted in in a while to be fair

I am PVS 1 I can only under volt by -25 tops. Anything more is a crash on bench... Sucks. So no point in even undervolting for me.

Hey guys.
What is pvs? What does it mean and how do i find out?
