Voting for adding "smartass" governor to i9000 froyo/gingerbread kernels

hi guys..
i opened this thread in order to hopefully urge all developers, and kernel developers in particular, to consider adding the "smartass" governor to the list of cpu governors already available...
before anyone asks, here's what the governor developer said about it:
Technical Details-originally posted by erasmux :
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!
also here's more on other governors in addition to the smartass governor in this thread
so what is this about??
"almost" all kernels available for samsung phones are missing this governor, and as some might think "hey, we don't need it..".. well i also own a samsung vibrant, and one of the devs there (ECOTOX) was so kind to add the goveror to his existing kernel called "SuperDragonModz", and the result was fanf*ck*ntastic.
here's what one of the guys at the kernel's thread had to say about it:
a4 moda said:
Eco, omg. Wtf. This new governor ands native functions if the kernel are simply amazing.
Smartass is so fast and efficient! ! !
Way better than conservative or on demand, one is schitzy ands the other is too battery strenuous.
Great FF+$% job! ! !

i had owned a few HTC Android phones in the past couple of years, and all the kernels there have smartass.. i don't think the devs there add it for no reason!!
this is about spreading the "smartass culture" among samsung rom/kernel developers..
what do you guys think?

I don't know enough about it but what you have detailed there makes me think it's a good idea.

Damn good idea, smartass rocks

This is an excellent idea, I've used in the past

You should be using it now, your sig says you own a htc hero, i'v had one in the past, smartass was one of the reasons the phone was so fast(for a hero), and yet battery efficient..
Look for flykernel 11c.. You'll love it

am i missing something here?!

Most kernels for i9000 dont have smartass, so probably its only because few people know that they like it or not. Or the thread title is intriguing for people that dont know its a cpu governor hahaha

glitch use it in his cm7 kernel, and that is by far the fastest kernel available for the sgs

Yeah some cm7 kernels have smartass, but almost no samsung kernel has it.. Only SuperDragonModz for the vibrant.. We need i9000 kernels to support it to get the most out of our devices..

Perhaps changing the thread title might help, there's already too many smartarses on here

+1. Change the title.

bumping for composure

really want to try smartmass governor.

smartass cpu governor for i9000
+1. I'd like to see it included for i9000 galaxy s

thanks for the support guys, this goes to all those who voted and didn't actually post anything also
i hope this gets attention from devs, hopefully by the next update(s) for froyo/gingerbread kernels we'll start to see something from the devs..

Its already in talon kernel, you just have to go and change it to smartass in the configuration files.

[Arrows - Guide] Best Aosp GB & ICS Roms [Updated - 1/22/12]

Feel Free to post and give feedback ^_^
Also feel free to Vote the thread ^_^
Q&A is in Post 2
_____________________________________
Hi Everyone, Arrow here and this is my guide to find what is the best aosp setup for your evo or android. It is true when people say "every phone is different." However there is an average of people that get similar results. At the moment people have different interest such as some people want performance and some want to improve their battery life. Of course certain people want both but only some get both.
*Remember what i put here is an average and may be different on your evo*
AOSP GB ROM'S: Ok so to start off, these are aosp roms still being updated as of now.
CyanogenMod 7 (CM7) - The most famous aosp rom out there, all or almost all other aosp roms are based off of this rom. This rom has a stable rom and experimental nightly builds. Anyone will tell you that you can't go wrong by choosing this rom. and believe me you will enjoy it.
CyanogenMod 7 Thread
Miui - This rom has the longest battery life and is very customizable. This rom is based off of CM7 and is an excelent rom. However unlike CM7 this rom does not have 4g so if you are willing to sacrifice 4g then believe me this is your rom.
Miui Thread
Gingerbread Evo Deck - Ok so although CM7 is amazing decks gb rom has said to be the exact same thing but giving off better battery life. other then that it is pretty much the same thing with some minor tweaks and some bloat ware removed.
Gingerbread-Evo-Deck's Thread
Xplod E4G - Team Nocturnal designed this rom and it is pretty much CM7 with the Sony Launcher + their apps. This rom will give your phone a nice cool feel that other people don't have. If you like a lot of eye candy then get this rom because it is CM7 just with a different look and feel.
Team Nocturnals Xplod E4G RLS1.2
teh roxxorz said:
using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.
Click to expand...
Click to collapse
ICS(mod7) - Team Blaze designed this rom and you can consider this rom like Xplod E4G, a rom just like CM7 with some minor tweaks but with a different look and feel. None the less this rom has something very special this is the closest rom to being like ICS (Ice Cream Sandwich). I 100% support this rom because they are doing the best they can to make this rom look and run as smooth as ICS. so if you want to look like your ahead of the game definitely get this rom.
ICS(mod7) Thread
AOSP GB Kernels: These are three kernels that i know of, if you know of more please let me know and i will add them.
Tiamat 4.1.0 - This is the latest kernel made by Tiamat and this is the only aosp kernel still being updated. This kernel on average gives people great performance but lacks on battery life. The main Governor for this kernel is SmartassV2 which is a balanced governor, good to turn on your phone and good to use on a normal day to day bases. For this kernel i do recommend using this governor. It does have SBC and Non-SBC kernels. *Side Note* (Some people say Tiamat 3.3.7 works better for them and is also known as the LEE Kernel because it was awesome like Bruce Lee and looks like Lee backwards [337])
Tiamat Website I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen - This kernel is no longer being updated, however it is still amazing this kernel seems to be Tiamat's competition. Where Tiamat lacks on battery Savaged-Zen does not. However it's performance is not as good as Tiamat. This Kernel comes in two version BFS (Brain F***ed Scheduler) and CFS (Completely Fair Scheduler). BFS is said to give better performance and CFS is the normal kernel. This kernel only comes with SBC however you may download "SVZ Manager" which will allow you to turn SBC on or off. The main governor for this kernel i believe is on demand However i use smartass and a lot of people us InteractiveX.
Savaged-Zen CFS sbc I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen BFS sbc in attachments (At The Bottom)
SVZ Manager I also put the Zips in the Attachment (At The Bottom)
GoDm0de - This Kernel was made by toastcfh and is no longer being updated. It is non-sbc and in my opinion definitely the best non-sbc kernel. This Kernel has insane battery life and a pretty good performance. If you do not want to use an sbc kernel i recommend for you to 100% use this kernel. The Governor for this kernel is set on on demand (i think) however i got the best battery/performance using Interactive.
GoDm0dE Kernel I also put the Zips in the Attachment (At The Bottom)
AOSP ICS ROM'S:
ICS rom by: the_Plattypus and it is still in Alpha testing. however the development for this rom is moving really fast so hopefully a beta will come soon.
EVO 4g Ice Cream Sandwich from source
ICS-evo-deck: This Rom is by kushdeck, After testing out Decks ICS Pre-Alpha 4 & 7 rom i conclude that although it is a alpha it can easily be used as a day to day rom. extremely fast and very snappy. only thing that i found not working was the camera. (Now on Alpha5)
[ROM][ICS][1-11-12][WIP] ics-deck-evo [alpha5]
All Decks ICS Pre-Alphas
All Decks ICS Gapps
AOSP ICS Kernels:
Jaredthegreat ICS - jared has the most advanced ics rom which is in beta 2 but does not have a working camera to check this rom go here:
[ROM's] -ICS- 4.0.1-4.0.3>[AOSP]<--~B.2.0~
Will post them when they are released!!!
Rom Manager/Kernel Manager:
Rom Manager: This is an app from the android market and is extremely useful for pretty much anything. you can back up your rom, you may go into boot loader and you can check if certain roms such as "CM7 Nightlies" have been updated. However people do prefer Amon Ra for flashing, which is another plus of Rom Manager it allows you to flash alternative recovery, which will flash Amon Ra for you.
Kernel Manager: This app was working before but has stopped now, however if it does start working again what it had was pretty much all the kernels that you needed for any rom. this app would allow you to flash a new kernel immediately by going to the kernel you want to flash.

Reserved
Q&A:
Q: What is SBC?
A: SBC stands for super battery charger. SBC is trickle charging, It stops your battery from dropping from 100% to 90% right when you take it off the charger. Some say that it harms your battery but i haven't seen any harm and plus it only costs $5 to get a new battery on Amazon.
Q: How to set up and flash your roms and kernels?
A: well my friend "Crossrocker" made a guide for this with everything you need. so just click to go to his thread. [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q: What is the difference between governors?
A: This Thread by "RJackson" explains it all:SetCPU governors (explained)
But if you're too lazy to click it here they are:
As explaind by RJackson:
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. - SetCPU website
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. - SetCPU website
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 the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive - The 'interactive' governor has a different approach. 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.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
As explained by MDJ:
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 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more![/QUOTE]
As explained by teh roxxorz:
Lagfree - like the performance governor. It will scale the cpu to higher frequencies when needed, but not to 100% like performance, so you'll get a lil better battery out of it
SmartassV2 - A smarter smartass governor. Code was re-managed/removed to make it more optimized, and have better scaling performances
InteractiveX - a better interactive governor I believe; low scale cpu settings, for texting, browsing, ect, nothing intensive. I wouldn't use it for emulators, ect.
Q: Do you need PRL/Profile/Radio updates? Do you need to go back to sense based to do these still?
A: No you don't have to go back to sense to do these and you don't have to do these because Rom's will come with what you need. None the less if you would like to update your radios here is a thread by "Calkulin" where he keeps the latest radios updated: [ Radios ][ 9-5 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions
Q: Does HDMI mirroring work on these roms?
A: As of this moment Miui and CM7 both have HDMI mirroring working, and sense all the other ones are cm7 with some tweaks they as well have HDMI working however from what i have read the only one that has not had problems with HDMI is Decks Gingerbread Rom
Q: Are all other major features (4G (except for Miui), bluetooth, front & rear camera, GPS, apps such as Netflix, Skype, Google Voice, Sprint Visual voicemail) all working at least as well as on a Sense or stock ROM?
A: Yes everything is working, however on CM7 and i presume on some others you also have to flash a gps fix which you can get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration. and the Voicemail seems to have some issues for some people but works flawlessly on Decks with it's gapps + Voicemail which you may also get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q:My wifi is connecting/disconnecting after a second, what should i do?
A: This answer was given to me by "teh roxxorz." This has nothing to do with your rom or kernel, do this:
Back up everything into Titanium Backup
Boot into recovery
wipe cache, Dalvik, and pretty much everything
reflash your rom,kernel and gapps (or if you would like to check out some other roms and kernels just click on the link in my sig)
once you've set up your phone download Titanium Backup from the market
in titanium backup restore all your apps ONLY!!! (don't get apps w/ data - only get apps, and do not get system data)
after this your wifi should be working just fine
Q: I am having wake issues?
A: Here is a Guide made by JBabey[FIX] Wake Issue (Android OS) - Combination of Radio/PRI/NV/Wimax/GPS !Solved!
Q: Can i make my 3g speed faster?
A: Yes, This answer was given to me by teh roxxorz:
You need to flash a sprint sense rom. I emphasize sprint because it won't work on the sense 3.5 roms, as they're all ports of other non sprint roms.
1. Flash sense rom
2. Obtain your msl, download msl reader from market, use it, write it down
3. type in ##3282# , input your msl (you can get this from the app msl reader)
4. Click edit mode > advanced
5. Scroll down to HHTD proxy port and address
6. Change the proxy port to 0 and proxychange the address to 0.0.0.
Q: How can I fix my GPS?
A: This answer was given to me by teh roxxorz:
- flash a sense rom
- open up the dialer
- Type ##GPSCLRX# or ##4772579#
- Your enter your MSL at the prompt
- Your phone will soon reboot > done
Q: Is there a guide like this but for sense roms?
A: Yes if you are looking for a sense guide rather than aosp then check out this thread by tropicalbrit
Q: What is your setup at the moment?
A: Rom - Decks 4.0.3 Pre-Alpha 7 ICS Rom
Kernel - Stock
Governor - Conservative
CPU Max/Min Frequency - 729/128
IncrediControl (app) - (-100) [I get to (-100) by first doing (-75) and leaving it there for 3 days and then I do another (-25)]

And any reason you were gona message me?

Hi,
Thanks for guide... I am considering changing from

Some features that you don't mention or summarize
that may help me and others.
PRL/Profile/Radio updates? I believe you need to
go back to sense based to do these still? [yuk]
HDMI mirroring?
Are all other major features (4G (except for Miui),

All ICS ROMs Benchmarked
Any regular visitors to this thread can't have failed to notice the big changes in the spreadsheet. In particular I've been studying the effect of the kernel the ROM developer includes. If you look at column H, you will see whether I recommend flashing another kernel to improve performance at stock speeds.
REMEMBER: Performance is not everything! Many custom kernels provide extra features!
If you do decide to switch kernels, and only desire stock speeds and a reduced feature set, I recommend two kernels in this post.
If you are new to this stuff read this.

Thanks to all the developers.

Testing Methodology
Each ROM is clean installed, allowed its own default settings, then all benchmark software is installed and run once the system is settled. I also perform one screen off screen on, just out of habbit (this used to resolve a graphics bug in gingerbread, which I'm not even sure exists in ICS). All results are recorded in the spreadsheet. Then I restart in recovery, wipe cache and dalvic (thanks morfic for dalvic wiper) and install morfic's T132-I kernel. Reboot, use nstools to select performance (default I/O scheduler for morfic's kernel is deadline). Reperform all benchmarks, recording them in the spreadsheet. The calculation for the overall CPU RAM I/O and GRAPHICS scores is identical to the one I use in my kernel benchmarking spreadsheet. Please refer to that thread for more detail. However, there is one difference. Quadrant behaves very differently in different ROMs depending on what graphics tweaks they incorporate. As such, no Quadrant scores are used in this ROM benchmarking study. For more details, see under 'Graphics' below.
The final step was to average out the results of both kernel scores, and ranking on that basis. Some would say that they are best ranked by looking at T132 scores only. I would say that is a fair point, and definitely worth consideration.
There are two reasons I incorporate the default kernel score:
1) Overall scores have a worst case scenario accuracy of within 2% of the true mean due to variability in the benchmarks (more detail on how I obtain this figure is available in my kernel benchmarking thread). For normally distributed data (which we can safely assume these benchmarks produce) averaging two sets of results will result in doubling the accuracy to within 1% of the true mean, making the ranking more reliable.
2) Combining the default kernel Scores for ROMs that used a poor performing kernel, or selected bad governor/scheduler combinations by default will suffer as a consequence. These problems can be solved if the user flashes their own preferred kernel and/or adjusts the kernel settings. However, many new users will not perform this step. For that reason, I want to give a score that at least somewhat reflects the performance as the developer intended.
-Graphics
One of the early findings is selecting force GPU rendering in the developer options improves 2D performance, in Quadrant only. Also, and only in Quadrant, 3D performance can be improved by deleting or moving /system/lib/egl/libGLES_android.so using root explorer or equivalent. These tweaks/hacks do not seem to affect other benchmarks in the slightest.
Because of the bizarre effects of these tweaks on Quadrant scores, I have removed them from the formula that calculates the overall GFX score, and this in turn impacts the overall average score. In short, it makes comparing each ROM's score fairer.
You can see evidence of how the graphics tweaks make Quadrant behave differently at the bottom of the spreadsheet, highlighted in light red. The host ROM for this particular comparison was DianXin or DX ROM for short. This is a reference to a post I make in DX ROMs thread, where I first decide that removing Quadrant is the best option: http://forum.xda-developers.com/showpost.php?p=22323688&postcount=194
-Android 4.0.1
These ROMs (at the bottom of the spreadsheet, highlighted in light red) were based on early maguro ports provided by koush. I have left them in, because although they are difficult to compare to 4.0.3 builds with the correct drivers and whatnot, they do compare to each other in one important respect: the kernel. One is stock, the other is built by eugene373 (galaxy nexus/nexus s dev.) Using eugene373's kernel, CPU, I/O, and Graphics were all raised to a high standard that is on a par, or above some of the current ROMs. This goes to show that a customised kernel can offer great benefits, even on a ported ROM.
-Android 4.0.4
As of the 5th of February, my table contains all the ICS ROMs that are listed in the XDA forums. There was only one 4.0.4 version at the time, and this was the best performing in the benchmarks. When the source code is released, I'm sure many ROMs will update. At this point they will benefit from increased RAM scores and javascript performance. If all the ROMs scores improve by the same proportion, the rankings will not be affected. I will attempt to included major releases, but I will not reperform these tests every time there is a new nightly.

Don't you think "popularity" is going a little too far? It will definitely lead to fights...all the devs are good and I don't think prominence is a good indicator of a good rom
But it's up to you

Personally, benchmarks are very misleading... Some of the most stable and well developed roms don't get the greatest scores because they weren't made with benchmarks in mind.

just remember, popular doesnt mean better. but to get angry at the truth(whatever it might be) is just silly. its lies that you should be upset with.

Where's Peter Alfonso's ROM? Bugless Beast is a mainstream rom, second only to Cyanogenmod in scope and breadth.. The ROM thread is in the General forum, because he links to his page at Rootzwiki, but it's a more prominent ROM than many you've listed.
Please include it in the benchmarking as well.

you didn't add and test this one

please add pete ics bugless beast.

Omissions fixed!
UPDATE: kwiboo's project removed, was an SDK port. So so tired now, got to sleep. Tomorrow begin again with Brainmaster's tweaked ICS

Which kernel is used to make the tests?

Haha, that makes me feel good. Wait, Benchmarks > XDA thread > Positive XDA user feedback > Dopamine release = Addiction to benchmarking? Time to join crackflashers anonymous...

Don't you think "popularity" is going a little too far? It will definitely lead to fights...all the devs are good and I don't think prominence is a good indicator of a good rom

I doubt it would lead to fights between devs, well hopefully not. I can see users arguing stuff more than devs.
Benchmarks aren't that good anways.
BTW, your kernel sucks!!!!
Just kidding been running smoothly since I started using it the other day

Thanks for the ratings system. Looks nice!

[REF] Memory Allocator Benchmark

This one will be of more interest to kernel developers.
Link to Spreadsheet: Results
RcrdBrt asked me to see which memory allocator performed best, and provided me with four identical kernels except for the allocators being SLQB, SLAB, SLUB, and SLOB.
SLUB turns out to have a slight performance advantage, as RcrdBrt had suspected.
The rank was:
SLUB - 980.56
SLQB - 972.17
SLAB - 967.72
SLOB - 967.72
Not much difference really, but every little helps, as they say at Tesco (Britain's leading super market/Religion).
Thanks to RcrdBrt for trusting me with this nice little study, and to Chainfire for the very useful benchmarking app. (See here)
Methodology
Technical detail (it's not necessary to read this!)
I used CF-Bench to obtain values for:
Native MALLOCS
Native Mem Read
Native Mem Write
Java Mem Read
Java Mem Write
...and used statistical methods to boil 10 passes for each allocator down to one final score: 10 passes is enough to get the mean and median within one percent of each other, i.e. establishes a confidence in the mean, assuming normally distributed data. Three standard deviations are subtracted from the mean, to show the minimum score we'd expect 99.7% of results to be above. This is to penalize variability (high peaks are less significant than a good consistency). The geometric mean is taken of the five end results to provide one final score.

Bedalus can't live without benchmarks. Closed UX benchmark yesterday and opened a new one today
One more instructive and helpful benchmark buddy

Most kernel developers prefer using SLQB. Any thoughts on why this is the case? Do they have a special reason for that or just a matter of not knowing better? Cheers!

RcrdBrt said it was the fashion! Tbh i don't know the differences between them, but some casual googling showed that slub has had success in other Linux arenas

Buzzwordism. The other 3 are in kernel.

You mean all those allocators are present but they mention only SLQB because it's the trend?

Correct.

Man, bedalus is really fast!
@morfic:
So, in the ICS stock 3.0.8 kernel, how many and which allocators are present?
Am I correct to say that all those four allocators are present, but only one is used?
Sorry for these dumb questions.

SLAB, SLUB, SLOB are in most (mainline) Linux Kernel, SLQB is patched in.

bedalus, did you run this on GB too?

I can do it if i have 4 identical gb kernels (except for the allocator) ... If you'd like it testing you'll have to build them for me?

[Q] Stuck in choosing ROMS/Kernels. Please helps!!

I am looking for a good combination of Rom and Kernel for maximum Gaming experience. Currently, im using Jr11 and motley kernel, and considering going back to Glazed rom which is imho the best rom for gaming. What do you guys think? Please give me advices. TIA

Before you get flamed by others for having clearly not read the forum rules, I'll say now that the only way to know is by testing them out for yourself.
Afterall, what works great for someone else could work terrible for you.

this is the only correct answer. try them all out, find what your device reacts to best and what fills your needs the best.
that said, my device likes trinity kernel with the rasbean jelly rom.

I use ParanoidAndroid 2.99 Beta6 with Franco kernel r30. I undervolted it too at [email protected] 1,3ghz down to [email protected] 100mhz and i can run the [email protected] 550mhz without problems. I haven't done extensive tests but i think that overclocking the gpu would give the highest gains in terms of gaming performance, but i don't exclude obtaining a little extra performance or more stable fps with some roms.
As the guys above said, it's a matter of taste, not every rom works for everybody.
