This kernel module allows you to run any stock HTC Froyo kernel with lowered CPU voltages. Reducing voltage decreases power consumption by the CPU, thus lowering heat and increasing battery life.
INSTALL:
You need root or an unrestricted recovery image (e.g ClockworkMod) to install this. The default settings decrease voltage by 75-100 mV which seems stable on my device (HTC Desire) and is reported to be fine on the EVO. Just download the attached file and select it from recovery or ROM Manager.
I've built "update.zip" files for the EVO 4G with Linux kernel versions 2.6.32.15-g746f4f0, 2.6.32.15-ge2fb08e, and 2.6.32.15-g59b9e50. You can check your kernel version in Settings->About phone->Software information.
Other HTC devices running Froyo are supported. If you have a different device, please give me the full version number and I can add an update.zip for it.
Full details and source are in the original thread in the Desire forum:
[KERNEL] Undervolt driver for the stock HTC kernel for Desire and others (2.6.32.15)
Update, 2010-11-22: Added driver for 2.6.32.15-ge2fb08e.
Update, 2010-11-23: Added driver for 2.6.32.15-g59b9e50.
recant: love this idea when trying to keep this stock
Sounds like it would go well with Fresh's new rom.

Too weak... funny considering there is more work involved in setting this up than most linux guys even do on a pc... let alone a phone.

Maybe not. I run the netarchy kernel but don't OC because it seems to crash at random times. I use it because the battery life is better than stock.
I'll revert to a clean back-up and give this a try just for giggles.
I would like to see some results.
I say that because I have tried a few havs roms and get worse battery life.
I think what a lot of people don't realize unless they are heavily into overocking is that microadjustments just dont have much effect there needs to be some substantial drops to really have any effect on battery and heat.
I realize that this is no desktop or laptop cpu, and that this cpu is based off such low voltages but such minor voltage adjustments, 80-100mv just arent going to have the desired effect unless that equates to a "substantial" voltage drop.
Not to mention the fact that most of you are going to overclock your phone without the faintest idea that doing so, even with a lower cpu voltage, will still cause worse battery life. This is a fact.. to argue it is futile. Its the nature of the beast.. do some reading and find out for yourself.
You can overcome some things by using on demand overclocking but you have to do extensive testing to find the sweet spot.

Nice work. I'm not interested in oc'ing, nor flashing a custom kernel. I may give this a go after a few others check in w/ results. I just want to know that it's stable.
I went to your other thread and saw the source. Clever solution, nice work. I really do like that you wrote a device to /proc that does a little more than report the frequencies back. This will make it very easy to write some scripts, or even a UI, that lets me tweak the settings. Hopefully I have some time to work on that in the upcoming weekends.
Will take a look at this first chance I get. Trying to finish my battery logger since everything available now doesn't log exactly what I want to know. Kudos.
Does this make HAVS obsolete ?

Undervolting meaning only when screens off or on and off ?
I installed and will get the best battery life yet. Better than when I was with King and other kernels....thanks!!!
Anyone have any results from flashing this yet? How is battery life? Any stability issues?

No stability issues and it seems to help on battery a little bit but I really can't tell a big deference. I was expecting for it to help out more. Thanks anyways OP for the share
i did say those little microvoltages aint gunna make any difference.
plus if you try to overclock you just cancelled any lowered voltages and actually cause higher power draw than stock mhz at stock voltages.
higher mhz equals higher power draw whether you have it undervolted or not.
you have to make a signifigant drop in voltage to make any difference at all. let alone if you try and overclock.
not trying to dog the guy who discovered this i am just sing plain and simple math, heat, and electronic voltages.

This isn't a kernel its just a couple of files that go with the kernel. One file for initial boot ect/initd and a .ko file that goes in system/lib/module folder.

G2X
CPU overclock is something that makes sense for us right now but what would a GPU overclock get us? To me thats just something that will lower the life of our phone with no real reward until games come out that our phone can't run. Right now our phone can run pretty much all games at full speed.
gpu overclocking would be sweet... now my question would be has anyone tried to load Optimas 2x kernel/software on the g2x since they are pretty much the same hardware(in theory you would think it would work)... i might even try to load this kernel onto my phone when i get home from work so if i mess anything up ill have my gear to fix it

I remember reading a while ago that GPU/System bus overclocking was attempted by some kernel dev, then later on, the dev realized through extensive testing that GPU and system bus clocks were locked, the changes to the kernel source had no effect (hardwired). Now this was a few months ago when I was reading up on Tegra kernel development before I got my G2x. Now all these could have been obsolete, and maybe now someone has found a way to do the above via kernel source updates.
Another issue that most people don't mention here and many people have been guilty of, is the GPL issue. The guy who supposedly did this overclocking has not published his kernel source code anywhere (GPL/XDA rules issues), so no one can examine what he did and prove that it worked....

Someone in another thread tried this and it messed up their baseband. A restore doesn't fix it apparently.
Big rush dog, the tiamat kernel guru and Guy getting engadet headlines for oc the xoom to 1.7 ghz has gpu oc in his kernels. I will be honest though, I can't tell the difference except maybe video streaming works a little smoother. I personally don't think it is worth the devs time...
Sent from my LG-P999 using XDA App
Howdy! I'm the developer of that kernel
To be honest the GPU overclocks aren't all that beneficial. There is a little bit of a speed bump (I managed to get the highest score on nenamark2 for example). But the difference is was 27fps vs 32fps. If someone is interested in incorporating that into the g2x I'll be happy to show them the changes I've made. I haven't released the source because I'm lazy but there isn't too much to it.
Actually, if you look at the voltKernel sources for the O2X you'll see the same changes there.

Yes, superficial benchmarks like quadrant can be pushed to 5400 only with max cpu oc.
However, did you notice how 1.2 thru 1.5 gets you the same fps with no added benefit than more heat created?
Pushing other things other than cpu should let us remove bottlenecks and not tighten them up.
If you want your G2x to life 20yrs, 1.5ghz is not the way to go.
I have no kernel ready for release, to notice changes, I stuck to 1.5ghz, but the final result will be more likely 1.2 or 1.3ghz.
Maybe with a "don't hold my hand, give me freedom or give me death" DBU version at 1.5Ghz later.
I'm not shy to increase vcore on a SoC. But unlike the Nexus S, this thing gets HOT, fast.
Avetny pointed out that thread, I'll see if fallout hit something I have missed so far.
The clocks get compared to chip defaults in many places, choosing the smaller of the two, so it's just tedious replacing them with sane defaults, unless I stick to my current approach of offsets instead of absolutes.
We'll see.
That's also the reason I don't update my kernel often. Right now commits in cm git are only preparatory, config changes that made things smoother I already used.
I'll release something if they finish their version of BLN.
Or if I'm happy with gpu/bus/ram oc/tweaks.
not going to make people flash a kernel for no reason. As jlevy can attest, kernel not following cm git, not even based on it can work very well.
Not having latest cm commit on kernels that take another approach is not always useful.
Especially if we track regressions that cm devs back out later, that's all this gains.
So yes, there will be a gpu oc, when it's ready.
Great!
@ fallout0 thank you i hope that you can help out one of our devs on this.

You should talk to Fallout0 he seems like he got past the system bus/GPU locked issue. both of you can maybe learn something new from each other. & it would be awesome if the both of you can work on a kernel together.
Wouldn't a higher clocked G2x cause more heat? Heat being the reason this things reboots so often? Maybe a slower G2x is the way to go.
Would overclocking the gpu help run nds4droid any better? What else would ocing the gpu do? Everything seems to be very fast as it is lol

Pushing cpu more I don't see useful other than keep up with your buddy's Nexus S' quadrant scores and make sure your hands stay warm in a cold Chicago winter.
I build kernels usually when things stutter or otherwise annoy me. The pushing the OC usually comes by request of those who just want more more more.
I do like to remove bottle necks.
The hardwired clocks. Well the.cpu ones are hardwired too.
The gpu/bus oc works, until boost and throttling kick in, where again values are compared to hardwired values. using offsets after the comparison would be the way around without killing boosting and throttling.
Guess main thing that stopped me is the heat at 1.5ghz, and the frowns over 1.2ghz and 1.3ghz kernels, without further "what else is in there"
Still hoping fallout can share what he/she has, it'll help making this a reality, sooner.
It's tedious. Most of all.
This post has been edited because I added Mandrobench results because it utilization of both cores. Mandrobench scores were identical for both kernels. Running Mandrobench at 1500 more than once tended to overheat my phone and cause reboots and other signs of instability.
One thing is clear, if you run either Faux or Trinity kernel you must OC at least to 1100 or you take a huge hit on performance.
I ran 4 different benchmarks on every configuration of CM 10 times with the Faux and Trinity kernels. I normalized the results so that each benchmark was evenly weighted and so the numbers are better understood they were normalized so that CM with its own kernel scores 100. All other numbers are relative to that. The 4 benchmarks were Quadrant, Smartbench 2011, Linpack, and Mandrobench. The results are a bit surprising, I am attaching the spreadsheet so that anyone can check my methodology.
CM w/CM kernel 1000 MHz score 100
CM w/Faux kernel 1000 MHz score 77
CM w/Faux kernel 1100 MHz score 104
CM w/Faux kernel 1200 MHz score 114
CM w/Faux kernel 1300 MHz score 123
CM w/Faux kernel 1500 MHz score 138
CM w/Trinity kernel 1000 MHz score 85
CM w/Trinity kernel 1100 MHz score 116
CM w/Trinity kernel 1200 MHz score 124
CM w/Trinity kernel 1400 MHz score 140
CM w/Trinity kernel 1500 MHz score 147
Test for each configuration were started following a reboot with a battery charged over 60%. They were run sequentially the same way for each configuration. Each number above was the result of the averaging a total of 30 benchmarks.
Interesting note, the first couple Quadrant scores on each run were generally lower than the rest, result of caching by the phone perhaps? On certain configurations the Smartbench results fluctuated wildly producing unexpectedly low scores. Not sure what the reason for this fluctuation but it is repeatable, at least on my phone, but only on certain configurations.
This took a long time, I am sharing it because I found the results unexpected and that they might be useful to somebody. Not everyone is dumb enough to sit and run benchmarks all day. Would be interesting to know how close the numbers are ran on another phone. I am intentionally only providing the numbers and my methodology, I will leave it to someone smarter to explain them.

I agree, Mandrobench should have been included, I didn't originally because it has disappeared from the market. I have searched my back-ups and found the apk, so I will incorporated them into the experiment later today. It is my understanding that most current apps do not take advantage of the dual core, therefore the results from benchmarks that are not optimized for dual-core have significance.

Both kernels were ext4, made much easier to switch back and forth by the new version of clockwork.
Both of these are file systems and ext4 is newer and theoretically faster, probably more so on a computer where there are more read/writes to disc. I don't think any of these benchmarks test for this. Someone else may correct this as I don't know a lot about phones, I am a computer guy, and an out of date one at that.

Running consecutive benchmarks can kill a battery in 2 hours.
Battery life is a subjective, I haven't thought of a way to objectively test it. I feel I get the best battery life with CM with its own kernel or Eaglesblood Froyo. Bionix appears to eat batteries.
After seeing these results, I plan to run the Trinity UV11 kernel for awhile and see to see how good the battery life is. The performance increase appears significant for only OC to 1100 and I like the idea of getting the advantages of a little OC/UV without having to run Pimp my CPU.
I have gotten a clear increase (hours more idle time) by simply turning off 4G and only toggling it on when I need it. I use Pandora a lot and it ironically runs better at 2G when I am bicycling (less drops interruptions in the streaming as I move around).

Faux's newest kernel is ~1.5 correct?
He's probably using the Trinity battery saving kernel clocked at 1.1 and undervolted.
I use the Trinity 1.1GHz kernel and undervolt to -200mV (for the lower ones, leave the top three at stock for stability reasons) and I score around 6100 in Antutu.

That makes sense. I just did a benchmark @1.1ghz and I got 6007. Ya the Faux kernel max is @1.5ghz. Its undervolted too, not much, just enough to get great battery life.

It's a significant difference. I don't have any data to back it up. But I've accidentally left it on the max after a benchmark and it would be in a free fall. Especially when playing a 3D game like MC3

I've tried using both Kernels as well as stock. Granted they both seem to run better then stock, I'm currently on Trinity with Standard Voltage, because the Under voltage versions of both Faux and trinity seemed to freeze on reboots for whatever reason. They both appear to run about the same set at 1100 which is what I've set to.
I'd like to say thank you for performing scientific and useful benchmarks!
Yes, I FINALLY did it!!! I overclocked my G2X. I would appreciate if anyone could share their experiences with o.c. pros and cons... Should I retreat or stay where I am? Please some feed back!
Over 1300 seems to cause trouble on mine.
i dont think oc'ing is really that necessary with a phone this fast but if u must i wouldn't go above 1.3 (just seems unstable above that). I think the "Pros" come from being able to underclock. Setting up profiles for uc'ing when screen is off or as battery level drops etc really prolongs the life of the battery (at least in my case)
On my OG droid that came limited at 550 mhz, ya, oc'ing was def necessary but I cant really think of any "Pros" for oc'ing this phone.
each phone is different though so play around and you'll find a combination that works great for your phone, good luck
Well... you can get some serious bench scores... This thing rocks the Mandelbrot multithread test in smartbench 2011 at 1.5 ghz. Other than that it helps with games.

What about the CPU not having enough cooling and frying the CPU over time. I presume its just like Desktop overclocking but without all the extra cooling you can add to make it safe for the hardware.

But what i really want to know is if oc could damage the phone. After all if there is that danger it's noy worth it...
In all honesty I used to be really into benchmark scores and OCing the heck out of my phone and under volting it in the process but that led to many battery pulls ect. What I've noticed is just keep it at stock and mild uving seems to be the best for me its stable decently fast just 2 cents though
Overclocking a cpu is the same as on a pc, only a bit more dangerous on a phone. (This phone already has overheating problems running at stock speeds ) On a computer, people pay a premium for parts that are easily overclocked, and have either very good fans/heatsinks or a liquid cooling rig.
Overclocking is dangerous, especially because not all chips are going to be made equal, even if they come off the same production line. These chips are designed to run at a certain voltage, and certain clock speed. As far as real world use, (NOT benchmarks. Sure, they look pretty and all, but benchmarks are never very accurate.)
Sure, you might get 2-3 more fps on your games, but is that worth the risk of shortening the life of your chip/phone?
(And just so you know, I've been building/overclocking pc's for years, but I also understand what you need to do to keep it stable, and it's *all about cooling*.)
If you're not convinced, try this. Don't overclock your phone, and use it for a few days. Tell me honestly that you really notice a real-usable difference with the chip overclocked or not. (Games set aside, but like I said, getting a couple extra fps on a game to me isn't worth the risk without a proper cooling setup)
For those of you that really don't understand what you're doing to your chips when you overclock, I'd suggest doing some reading about it. A good place to start would be here: http://en.wikipedia.org/wiki/Overclocking
So you think using fauxs kernel is not safe or reduces the life of the chip? I just flashed it and didnt oc or uv further then fauxs default settings...

I'm not saying it's for sure, I'm saying there's a chance.
Plus keep in mind that these kernels have other really nice additions besides overclocking and undervolting. I'm using faux's stock voltage kernel ext4, and leaving it at stock settings, and it really works great.
I just posted this up because I see a lot of people more interested in quadrant scores (which to me are pretty useless) than stability of their phones. If you do overclock, and it works for you, more power to you. I just want to inform people. I'd HIGHLY suggest if you aren't sure, read that wiki article, it's a great place to start. (not all information is there, but it gives a very good general idea on how and what overclocking is.)
Thanks! i always like reading knowledgeable and informative posts!

OK, you definitely convinced me.... I have also faux (let me tell you exactly - Kernel Version 2.6.32.9 FR Faux 123-v0.03) on EagleBlood 1.05. Could you please tell me what I need to do set up in order to be safe? Thanks!
I'd just go to faux's thread in the development section (his froyo thread, not the cm7 one, since you're using eagleblood), and download his stock voltage kernel. (It's in the first post.) He's on .04 now, by the way.
Then reboot into recovery, and flash the file you downloaded. It'll overwrite your current kernel and modules with the new one, then reboot.

I could not find this thread under G2X Android Development Section... I found threads Kernel Trinity, Kernel CM7, Kernel LGE Stock Froyo, Kernel Morphine... Which one is it...? Please do have some patience, at least I learn fast!

You passed right by it. LGE stock froyo. (That doesn't mean it's a stock froyo rom, it means it's *based* on one )

Choose the stock voltage one. (ext3 or 4, depending on your preference.)

And a lot of times the kernel will be credited to the developer. So if you see "faux's kernel" people are referring to kernels by faux123. Trinity kernels were developed by morfic. If you are having a hard time finding a specific one, look at the top left to see who started the thread and sometimes that will help find it. Does that make sense? I had to pull an overnight at work so I am a little loopy....

So we all know the stock voltages are 1150mV across the board, but that just doesn't seem very effecient.
However, I have heard that UV really makes a very minimal difference. Others do it religiously.
Does UV really make a difference with battery life?
It all depends on how you use your phone. If you just use it to talk, text and surf the web then it isn't important. If you like to take full advantage of what your phone can do then undervolting is vital. It also depends on the phone itself and its battery life without undervolting.
I have the rev0 fast CPU and is made a very nice difference for me. Rev4 supposedly can't handle uv. I read this on the synergy forum. I don't remember the scripts to run in terminal emulator but that's how I found out. I was also on beans 11 with ktoonz kernel and used team kernelizer's setup and I was getting 5 hours screen time :thumbup:
