[KERNEL] smartass cmkernel 11/26/11]

This is based on the cyanogenmod kernel, with the main change being the smartass governor has been added and is default.
The zip file is in koush's anykernel format, so it can be flashed just like a rom.
Changes:
Smartass governor by erasmux is default
extra overclock enabled
patch #22 by farmatito
disabled CONFIG_SERIAL_MSM
NO SUPPORT WILL BE GIVEN. ONLY FLASH IF YOU KNOW WHAT YOU ARE DOING. NO ONE IS RESPONSIBLE EXCEPT YOU. BLAH BLAH BLAH.

What does the smartass governor do?

smartass governor - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 - why?! - it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!
i googled it lol, seems like its a bit more responsive then interactive, and it ramps down quickly too. could give some battery savings

What ROM's will this work with?

keeps cpu at/above 768mhz, will not go below until you switch off smartass gov.
liking the "sleep" enhancement, but seems like it should let the processor scale on down to 245 when idle with screen on

I'm running this with CM7 Nightly #16 and it's running really well. I'm getting a little more battery consumption than I do with zinx's kernel, but that could just be because I've only been using the kernel for around 2-3 hours. It may need a little more time to settle? I'm not sure, but it is definitely snappier! If it does scale down the cpu during screen off, you can't tell at all! It doesn't have any lag when unlocking like setting profiles usually does. So I'm really stoked about this kernel! Great work as always Dumfuq! This will be my new kernel for at least a few days to give it more of a chance.
PS: I'm only getting around 29 on linpack at 1.017 GHz, where as with zinx's I was getting 38's. Smartbench scores are at 1320's for productivity and 1869 for gaming. So those both beat out zinx's kernel. Just wanted to put those out there so people have some kind of a comparison point.

posted a v2. The difference is frequencies are changed to match glacier frequencies instead of hero's.
The only noticable difference here is that when the screen is off the frequency scales between 245 and 368 instead of being stuck at 245.

Damn. Nice!

Works with evil's MIUI 1.1.26 r2..Hopefully battery life will increase now.
Edit: breaks video playback in miui

I use this on my GF's Mytouch Slide and she gets 20+ hr's on a charge overclocked @ 825. Was so hoping someone would port the kernal to this phone. thx dumfuq ^^

Trying to decide if I want to flash this over the stock cm7 kernel.
Has anyone noticed any gains from doing this? what about compared with the stock cm7 kernel + setCPU?

flashed this over build 16, cm7. I still use setcpu. no problems, everything is smooth like butter. Definitely smoother than it was before. no wake up problems, no play back problems. thanks for this =]

You could always flash it and find out, and if not, just restore the backup you made prior to flashing it. ;] I don't see why it wouldn't it hasn't broken anything for me.

K ill try it out later when I get home from work. Thanks

whats the mhz setting on this by default? not super fond of setcpu. though i do like this idea of a custom throttle and logic. so i figured if the mhz is high enough then i'll give it a shot.

[Q] How to safe overclock my XPERIA Play?

Installed the JokaWild v3 ROM on my Play and flashed the DooMKerneL v14 ,now i wanna know how to do a safe OC.
I'm using No-frills CPU ,can you tell me the best settings for good and safe OC to XPERIA Play?
Thank you

I dont generally OC my phone beyond 1.2 but you can use this app to run a sereies of tests to determine which OC speed is best for your phone as all phones are different.
http://forum.xda-developers.com/showthread.php?t=1656052

I don't overclock mine past 1.4. My play actually reboots if I go 1.6 or more.

I Overclocked my phone to 1.5 and it worked fine. Then tried overclock to 1.6 ,and it's really working good! no bugs ,very fast and the battery stays cool.
I'll stay with my 1.6Ghz overclock ,I think it's enough

What governor / IO scheduler are you guys using? i'm in the same position (jokawild / doomkernel v14 and just installed nofrills cpu) and have read the FAQ, but the version i have seems to have considerably more governors than what has been listed

I'm on SmartassV2.

I once asked this same question ot DoomLord, maker of DoomKernel about which governor and IO to use for best gaming and all around performance.
His recommendation (whihc I have been using since and saw a noticable difference) was to use
Governor: Performance
I/O: BFQ
and I overclock mine to 1.2ghz. My first android phone i oc'd too much, heard a popping noise and BAM.....bu-bye. So I dont go too far..

I generally step up the speed one step at a time until I hit errors that cannot be explained or I get force quits because the phone is running too fast. I suggest going slowly and testing things out but using the governor Performance while the phone is changing. Right now I'm doing okay with smartass v2 at .60/ 1.5 ghz. I might try bumping it up to 1.6 ghz and see how that works tomorrow.

Epic It is like the phone has no battery cuz on this governor, the phone runs at max frequency.

I know I'm mad late, but I was wondering why my phone kept rebooting. I uninstalled all overclocking apps so I thought my profiles would return to normal. Turns out I must have accidentally set the profile to 2ghz max and 2ghz min somehow. My phone was super lagging and thank God it didn't burn out, smh...

I currently have my Play overclocked to 1.6 using the interactive governor. Battery life is great and it runs steady at 60fps in FPSE. Also Mupen64 runs much better. I haven't had any issues with it so far!

What scheduler are you using??

Mine is running fine on 1.4Ghz with SIO scheduler and InteractiveX governor, the bbatery life seems fine as well...
SmartAss always causing lag on me, dunno why...

LUPUS_GB
i use lupus kernel for gb v2 with i/o setting SIO and governor superbad..
and my phone runs well...no lag..

Hey guys ive already overclocked my phone using the lubus gb kernelv12 and i gota say having the extra internal memory (EXTRA 400MB!!!) and the ability to overclock to 1.6ghz is nice, however there are some things i wana ask. Im running at a min 249 and a max of 1613 mhz using no frills cpu with smartassv2 as my governer and noob as be scheduler, it runs miracles in speed, everything i can run at high resolutions and play and top speeds. However i leave my phone like this all the time ( 249mhz 1613 mhz). The smartassv2 governer is ment to only use high cpus when needed, so that in theory means that i wont always be at 1.6ghz. Ive read on other forums keeping your phone overclocked all the time is bad and dangerous but is it really if the max cpu is only being used when needed? In otherwords should i leave it how it is or is it dangerous? My device is an xperia plat btw. :victory:

AFAIK only the Performance gov keeps the phone at the max allowed clock speed (1.6GHz in your case), so it's just fine as it is. You could, however, use an app (the only one I know that does this is SetCPU, there might be others) to make profiles so it'll only be overclocked when playing games/running benchmarks et cetera. This might save you some battery life.

CPU master by antutu allows you to set profiles but you need to buy the pro to do it

Much appriciated for your reply, and thanks button got a smack to.

Best Overclock settings specifically for the Play?

I'm using NoFrills CPU and want to find the right balance between overclocking, performance and battery...
What speeds and governors are everybody using for their Plays?

I'm using 1.2 Ghz max 130 Mhz min with SmartassV2 and sio. All seems okay to me.

I'm using 921mhz-122mhz intellidemand2 with sio governor and everything is smooth + battery is great

1401Mhz Max, 180Mhz Min (when Screen On), 785Mhz Max-180Mhz Min (When Screen Off)

So many different settings!
Was hoping there'd be a 'common' setting that everyone kind of determined was best.
Thank though.
Still interesting, and would like to see what more people are using still.

Mines currently 1.613 Ghz Max, 245 Mhz Min. Virtuous Governor, Noop I/O Scheduler.
On intensive apps I change the max clock to 1.901Ghz however this I don't recommend for most people.
I also only use 1.9Ghz when using Android 2.3.7 with DoomKernel, as only that Kernel seems to allow for voltage changes... Which i apply when using that kind of speed, whereas the default voltages are much higher for that clock than I usually set.
Everyone's Play is different, and not all Plays can sustain high clocks at specific voltages. You need to find your own 'sweet spot'.

Is there an app for that?

No.
You need to increase your clock little by little until you're happy. Then, if you're on GB using DoomKernel you need to lower the voltage as much as you can without it crashing if you want it perfect.
Most people simply oc though and don't bother with the voltages, but it will reduce power consumption and extend the life of your phone with the OC enabled.. As normally running your CPU past its specification will wear it out faster.

As DiKeJ said in his ROM thread:
In my opinion, interactiveX, and frequency of CPU 364.8-1305.6MHz gives awesome stability and performance

:good:

TRUE FACT.

you should use a kernel that allows you to undervolt... there was some article with the galaxy S3, where they tested different settings with OC+UV and YES, Under Volting gives better battery life!!
A lot of people here say, that UV will have no effect on battery, but they have no idea how a processor works... so they just should stfu!!

[Q] What is Intelli-plug, MP-decision. Which is best?

Hi guys,
I'm new to android and I just flash a cook rom with custom kernel to my phone.
I use Kernel Tweaker to set some variable to make it use less battery and smoothly but I see an option called Intelli-plug.
I google this and see it complete replacement for MP-decision.
So what is best of them for battery life and performance at cook rom?
(I think MP-decision is best for Stock rom, correct me if I am wrong )

Intelliplug is a replacement for mp decision implemented by faux123 if im not wrong . It determines the behaviour of the cpu and gpu. Stock nexus and OG only have mp decision. Intelliplug is a better option
Sent from my Nexus 4 using XDA Premium HD app

mp-decision is better.
The only thing the Intelliplug do is causing lags, freezes and other annoying strange things.
imho.

There's also msm_mpdecision (not to be confused with the mpdecision binary) by showp1984, which is pretty good. It has input boost and is the smoothest I've tried. I'd give that a shot depending on what kernel you're running. In trickster, it'll be a menu in specific called MSM-MPDECISION control (or something like that). CPUQuiet is supposed to be good as well, but I haven't personally run it. Auto_hotplug and mako_hotplug in faux and matr1x are typically better for battery than others, but are not quite as smooth.

If you are comparing stock vs N4, yes, they are different; stock should actually be a bit better since Qualcomm doesn't include certain things on Nexus devices. On CM, the mpdecision binary used I believe is from N4 4.2.

I don't see anything that is making Qualcomm MP-Decision better than Faux123 custom Intelliplug driver His hotplug driver is everything that MP-Decision is lacking of + more battery friendly and less heat generating..

MPDecision is much more aggressive in terms of changing CPU frequency (automatically goes to 1026 when input is detected). IntelliPlug is more for battery than performance. For performance, I suggest MSM-MPDecision from showp1984 (it's on most of my kernels and a couple others), which performs similarly to the mpdecision binary in terms of boosting frequencies and raw performance, but is customizable. You can change the frequency for input boost or turn it off altogether. There's a bunch of different settings you can play around with.
CPUQuiet also is one of the better performing hotplug drivers. I don't know quite as much about how it works, but it was made by NVidia and ported to Snapdragon by maxwen and has a set of governors which keep the CPU running at optimal frequencies for battery and performance.

In my opinion Intelliplug is extremely finicky and unpredictable. I get much better battery life with mpdecision.

I am a little newbie on this, so may i ask a question?
How can i install MP-decision?
Is it built-in on a kernel or do i have to download it seperately?

any body can completely explain what relay MP-decision and Intelliplug do? or any body know where I can read complete documentation of those?

MPdecision
Guys,
In my humble opinion what i have noticed is - when you enable a mpdecision i.e.on in the cpu, based on your cpu gov settings say for performance - one core of your cpu will always be at 100% and based on the activities it will switch on or off, the other cores.
When your cpu gov settings are interactively managed, again one of your core will be working and based on the certain % say 79 or 80,it will switch on the other cores.
If you deactivate mpdecision then almost all your cores will be active at any given time. But may not run as high as in enabled state.
So if you are one of those who cares about your cpu heating and don't use cpu tuners or sleepers. Set it off.
If you are into gaming and very smooth ui experience and doesn't bother about battery drain, switch it on.
I have enabled the settings and use custimized task scripts to reduce the frequency of the core as soon as i switch off the screen.

[Q] Safe level of OC? ElementalX Settings?

I would like to flash the Elemental X Kernel over CleanROM, and I am interested in slight OC'ing. I notice with the installer it sets the boot CPU and GPU to what you set it to during the install.
If I use trickster mod can I go back to stock if I set the cpu to 1.7ghz in the install?
I figured 1.7-1.8 would be a mild OC and no more than the preferred 450 for the gpu. What does everyone else use? I game a lot on the nexus but don't want to overheat the device too much.

Yes, you can go back to whatever frequencies you desire and for the heat, for me, it heats up no matter what
However these temperatures are normal so nothing to worry about.
I live in the Caribbean with a Tropical Climate and i run at 1.7 ghz with 450mhz for the gpu with not much heat problems.
