[Q] Best kernel for MIUI

I am currently using MIUI 1.7.29 Osimood with the Tiamat 1.04 kernel, and I am wondering what the best kernel is for battery life. I am also using the V6 supercharger ram script. I am running my CPU at 960mHz at the moment, using the smartass governer. I also undervolted using vipermod, 960MHz at 950mV.
My choice consists of the latest Pershoot, UmaroKernel 1.06 or Tiamat 1.04
What differences would I see between those kernels, are they noticeable for a regular user?

Sorry man, but wehre do you find the vipermod for desire z? http://vipermod.tiamat-dev.com/faq.php it's not compatibile with desire z/g2....

Uh...what's wrong with the kernel it comes with? Can OC to 1.5GHz stock ya know. Battery life is great with it too. People always want to flash something weather it be a radio or a kernel.

damn straight,
1) pershoot is a sense kernel? (i am proabably wrong but i have never tried this kernel)
2) umaro kernel i found had issues with wifi, high underclock freq (leading to poorer battery life), but fun if you have the time to tweak voltages and fast!
3) tiamat kernel i found had issues with sleep of death/random reboots on wakeup couldnt test it past that. (setcpu was set to screen off was: conservative 125min -345 max and would still crash)
if you are up for another kernel, i am now using this kernel (streamline5)
no voltage tweaking (pretweaked) but it has good batt, speedy and stable cant ask for much

Pershoot is actually for non-sense roms. The downfall people have with it is lack of governors. Some don't mind, some want variety. I've had great experiences with Pershoot's kernel and it's the baseline that all others are compared to (not to mention the foundation of almost ALL G2/DZ kernels).
Umaro's just needs to have voltage tweaks done manually but on the plus side - keeping the voltages normal (not UV) allows some people to reach higher OC speeds. It keeps the processor from bottoming out due to insufficient voltage which can easily happen when you UV. The main issue is with the Greased lightening governor - it's new and still a bit buggy.
Tiamat 1.0.4 is outstanding. I can sit all day at 2+ GHz (not literally, see: Chernobyl). I personally have an issue with the interactive governor but other than that it's my favorite kernel (Umaro may take that soon, once greased lightening is perfected).
Basically you just need to try out a few and see which you like. There is no 'best'. Most kernels will work with any ROM (Sense being the only exception).

Bumping a thread that is relevant to my interests.
It's about time for me to jump ship from an outdated CM ROM and try something new like a MIUI ROM.
With that said, I'd like to read more opinions & experiences from people using the various Kernels AND how the latest radio (the one released today) is working for them. I'm just trying to get the optimal experience here
Speaking of MIUI would anyone mind telling me some differences between OsiMood's ROM compared to the official MIUI-US ROM (or even DarkSpadez ROM)?
Thanks a ton guys!

I downloaded the official rom . . .then ignored it downloaded osimood and iv been using it since. Osimood is a lighter rom, which is always a good thing, unwanted languages etc are removed for a smaller faster rom. Also he preinstalls tweaks like an adblocker and extended settings mod.
Kernal wise iv been looking for the same info as you but couldn't find it. So I eneded up trying them all:
- Eugenes streamline5 is a nice kernal, preundervolted. Only probly is its not being updated so will become redundant.
-Tiamats kernal allows over clock to 2ghz and seems to support higher overclocks stably where other kernals can't. Except battery life has decreased with recent kernals
-Umarokernal this is the kernal iv come back to twice and am still on. It allows overclock to 1.9ghz and is kept updated by umaro. Performance per frequency seems as good if not better than most and osimoods miui runs smooth with this kernal on 800ghz with scarey governer (which saves battery) Another plus for me with this kernal is the scarey governer which for me definatly provides the best performance per battery ratio.

I'm currently running MIUI 1.8.5 with Eugene-Streamline 5 Kernel with the latest radio update Vision_Radio_12.57.60.25_26.10.04.12.
SetCPU with Governor ondemand provides me with better usage, power and responsive time then Smartass or Interactive.
OC to 1.2ghz
Battery life, about 30hrs with the regular 1350mah.

i just got 40 hours with similar setup but i use virtuous o/c daemon instead of setcpu
big fan of streamline5 and hope that it will get updated eventually

How do you get the virtuos o/c daemon?

Its basically like an automatic setcpu (which can't be changed on the fly) built into the rom, its in virtuous unity roms

What sleep profiles are you guys usein. I seem to have rebooting issues with any kernel I try unless I go to a sense rom. I've tried the vipermod now to see how it goes
Sent from my T-Mobile G2 using XDA App

But how do you get the virtuos O/C daemon to work on MIUI?

You can download it threw rom manager. Even with that kernel I get reboot issues. I assume its cause system ram isn't being cleard fast enough. I'm gonna try 100mv increase to see if there's a difference.

Ktweaker profiles? On d2tmo

I'm on free gs3 r6 rom with ktoonsez latest kernels (9-5 & 9-10), I'm using ktweaker but there are ni profiles to use except for screen off. I was looking for something like set cpu profiles. If i try to use set cpu profiles only with ktweaker, my phone gets hot and drains my battery faster, so i guess both of the apps are not compatible. Or what. Thanks for any help and suggestions

That is the ktoonez kernel.

If your going to try out ktoonsez kernel and you have set cpu, Don't use set on boot on set cpu, just enable the profiles and Don't set voltages too. In ktweaker enable overclocking steps but Don't lock frequencies. On both ktweaker and set cpu, you should have the same i/o scheduler, and the same governor. If both of then has a different governor or scheduler and clock speeds it will make the phone hot, i reached almost 40c or maybe more then my phone rebooted by itself, i was playing nova on 2.1ghz max clock. Lol.
Now I'm undervolting with ktoonsez suggestion on his post, and my min clock at 96, max at 1350, ktoonservative governor, sio i/o, and my phone is still fast and smooth. Battery life once never tested as i bring an extra one all the time, and i just bring a retractable usb cable for charging.

Stock GNex voltages

Hello,can someone please help me by telling me the stock voltages for the CPU,GPU and IVA? I have freezes with the basic voltages in franco's kernel SmartReflexand enabled.
I saw that some voltages from the CPU are decreased from the stock ones. I think my phone can't handle those voltages(maybe something chip-related) and I want the stock voltages and franco's kernel tweaks too
Im on AOKP milestone 1 (4.1.2) and franco's r300 kernel.

Up the voltages yourself until device is stable. And its indeed related to your chip quality.

I overvolted each freq in CORE with about 50 mV and the games that use to have many little freezes,now they don't i probably need to overvokt IVA aswell. The only thing that slutters now is when watching a video,and sometines when scrolling thru desktop pages and appdrawer pages.

Smoocha kernel -- AOSP 4.2.2

Here is a kernel Houstonn and I have been working on. It's based on Faux123 kernel for nexus 4, however, it has evolved into a "buffet" kernel. I keep choosing what i believe is the better interface / way of doing things in a choice of various way or what could give us better battery / performance. I'm trying to maintain a certain balance.
This version is for geehrc (Sprint/Internationnal) with the 13mp. If you have the 8mp phone (E973/E971/E970), use that thread : http://forum.xda-developers.com/showthread.php?t=2229742
I won't link to Faux123 kernel in the nexus 4 for the simple reason that 99% of the people don't read and on these 99% of people, a few will end up flashing nexus 4 kernel which mostly flash by partition number and not by partition name thus hard bricking their device.
Reason to at least try it :
CPU voltage table
Intellidemand and Wheatley governor added
All the block I/O scheduler
TCP Westwood algorithm
Faux123 sounds interface
Faux123 gamma interface (color control)
Newest Prima (wifi) driver.
In-kernel thermal watching
Msm_mpdecision (In-kernel OpenSource MPDecision)
Frandom module loaded at boot.

FransicoFranco Drivers
Thanks for making this kernel, it is much appreciated. I'm wondering where to get/enable the generic hotplug driver and the sound driver by FransicoFranco. Thanks.

I have a sprint lgog and I tried running the eos 4.2.2 ROM for a few days. The battery life was pretty bad compared to the lifeless ROM so I restored back to that. Anyways, will this kernel improve the battery life?

Try it and you will see. I am not giving comment on battery life.
On another note, Version ending with fs have faux sound instead of franciscofranco sounds interface

I've managed to get pretty comparable (not 100% sure) battery life on AOSP compared to Stock Roms. Not to speak for the developer but yes this will increase your battery life. The only thing is that there is a lot you can tweak which will have an effect on your battery life. This is what i do.
Turn mpdecision off. MPdecision is a hotplug driver made by qualcomm that can be disabled in AOSP. As of now its always active on stock roms. I'm still trying to figure out where to get the Francisco Franco hotplug drivers, which are prefered.
Underclock your cpu/gpu - I like to keep my max at 1026mhz and my gpu at 200mhz. I don't notice any significant lag.
Undervolt your cpu
Use a intellidemand/tune your on demand governor
Obviously wake locks come into play as well. I like to use better battery stats to see whats keep my stuff awake.
Finally keep your mobile data off when your not using it
Sorry if I'm just telling you stuff you know, just trying to be informative.

No more mpdecision. Msm_mpdecision in this kernel is different. It's opensource, in-kernel and doesnt force you to 1026mhz minimum freq,

sweet. I was using fauxclock to control my cpu. I am a little confused on msm_mpdecision
is msm_mpdecision the generic hotplug driver by FranciscoFranco?
Is there a more appropriate app than fauxclock to use?
If I disable mpdecision in fauxclock, does that automatically enable msm_mpdecision?

Nope, msm_mpdecision is not franciscofranco hotplug drivers. I had franco driver before and it lagged too much. Also, there is no mpdecision at all. I remove the executable on installation of houcha. Seems as fast as mpdecision without the locking the minimum freq to 1026Mhz.

cool, just for some feedback I feel that there definitely is a difference in my processor states when I enable/disable mpdecision in fauxclock.
When it's enabled, the first core sits at 384mhz until i touch the screen, then the first two cores jump to 1026mhz or 1516mhz.
When I disable it my first core sits at 384mhz and jumps up to 700-1100mhz when I touch my screen, the other cores stay quiet.
In both circumstances I'm using Intellidemand governor.
As long as I'm bugging you, My gpu frequencies are a bit wonky. It goes to 400mhz on boot. When I lower it to 128mhz it will sit at 128mhz and not jump up no matter what max frequency or governor I reset it to.

Try downloading the newest version. fs version have faux sounds, others have franco sounds. I believe faux app read gpu freq incorrectly. If you swipe tab (which is gpu demanding compared to stay to same tab) you will see the gpu freq actually lower.

Governors...

Rooted Stock ROM. http://forum.xda-developers.com/showthread.php?t=2387942. Havent changed my Kernal asfar as I know, but have adjusted CPU setting in ROM toolbox.
I currently use OnDemand governor with max slider at 1200Mhz. After learning that OnDemand is not too good for batterys life long term as I use my phone in short bursts and alot of multitasking I have found that SmartassV2 would probably be the best governor for to use. The phone is used to play media, games, browsing and sketchbook app, nothing too serious but I want the best balance between battery life and performance possible.
I understand playing with the kernal can result in issues but have not managed to find a guide on how to do this on XDA. Can anyone advise me on this or point me towards a simple guide please.
Thanks.

so ur using Stock Samsung kernel with ondemand ??
only governor on stock kernel that have cores hot plugging is pegausuQ AFAIK so ondemand will cause worse battery
