[1.267GHz!!!] [Devs] Overclocking/undervolting patches (update 6/15)

I got an EVO myself and managed to overclock it to 1.267GHz. We could probably go even higher, but that requires more extensive changes. Here are the changed source files: http://dl.dropbox.com/u/36553/supersonic_oc-uv.tar.gz
It also includes an undervolt courtesy of pershoot (a whole 0.1V lower when idle, which should help battery drain a lot!). Here is a test update.zip: http://dl.dropbox.com/u/36553/supersonic_oc-uv_signed.zip (working WiFi). Make sure to do a nandroid backup first!
Sensors/camera do not currently work in this kernel because the source is not yet complete.
There is an overvolt on the highest frequencies. It should not cause any issues. Thanks to toastcfh for his source, Herver for creating the first booting overclocked kernel on the EVO, all the kernel devs in the N1 community, especially pershoot and kmobs, richardtrip from the Desire community, koush for anykernel updater, and all who helped to root the EVO. Enjoy!
Update 6/15: Fixed 950mV undervolt. Raised voltages from 1228800 above to improve stability. Source files updated and update.zip uploaded.

I posted these in an earlier thread, but I think I should bring this to everyone's attention. Here are some simple patches that will overclock the Evo up to 1.267GHz (though by any means it's not guaranteed to get that high!):
Edit: please don't flash the below update.zip, as it doesn't seem to boot. Devs, the patches are still below, and a zimage is in the anykernel update zip.
Update: I compiled it myself. Here is an update.zip: http://dl.dropbox.com/u/36553/update-oc_signed.zip. This uses toastcfh's sources, Koush's excellent anykernel updater and a config.gz pulled from a stock Supersonic. If this doesn't boot, no damage will be done to your phone. Just reboot into recovery and reinstall your ROM. You can test overclocking by grabbing SetCPU from my sig or changing the cpufreq values if you know how. Once we get this working, I will create an undervolted version for battery savings. I'd get an Evo, but it's sold out everywhere T_T
http://dl.dropbox.com/u/36553/supersonic_oc.zip
cpufreq.c and acpuclock-scorpion.c are in arch/arm/mach-msm, and supersonic_defconfig is just the config. I don't have an Evo, so I can't test these out, but these should work with the source files toastcfh posted earlier: http://forum.xda-developers.com/showthread.php?t=686240.
Undervolting can be achieved simply by adjusting the voltages (in mV) in the acpu_freq_tbl table in acpuclock-scorpoion.c. For those not familiar with his work, you can see pershoot's safe (but lower) voltages for the N1 here: http://github.com/pershoot/nexus-kernel/blob/master/acpuclock-scorpion.c. If you want to overvolt or go under 1000mV, you have to make one further adjustment to the voltage regulator in board-supersonic.c.
Note that the N1 and the Evo are completely different devices (with similar processors), so what may work for the N1 may not work for the Evo.

I don't recommend overclocking, the devices already can run warm at current settings.
But then again, you are entitled to do as you wish.
Options better than overclocking are to remove the Sprint bloatware and strip down parts of Sense, this speeds things up alot by removing excess background applications.

Well it ain't too bad, my Droid at 1 ghz(550 stock) runs great.
So this should be good too.

I like overclocking as much as the next geek, but on the Evo... WHY?
This phone has yet to respond anything slower than instantly to my input and I expect a difference of .26 ghz would not make it so it could read my thoughts.
Undervolting, on the other hand, could help with the abysmal battery life...

Some people love to run benchmarks. Try to improve on them over and over. Others like the feeling of just going faster. Also some apps or some in the future might require a faster running phone. What better way to achieve that (other then buying a new phone) then OC.
Also in the future, are you not gunna buy a 1.5ghz processor phone running 2.1 because a 1ghz processor can already do it? OC has many benefits, just not to everyone, most because they dont understand the consequences or benefits.
My htc hero clocked to 768mhz can run 2.1 and everything near instant. Still doesnt keep be from wanting a 1ghz or higher.
Also one more thing, 2.2 will be out soon. With full flash support, i have a feeling its going to require a lot of CPU. An OC Evo would probably run many things from 2.2 a lot easier.

Well, I agree with the benchmarking comments but on the subject of Froyo... Froyo is designed to be even faster on equivalent hardware than 2.1... and 2.1 on my Evo is smooth as silk. And the Evo handles most Flash I can throw at it, so I'm not sure. I have however noticed a small performance difference with live wallpaper running, so maybe OCing will clear that up a bit.

You know, this is an excellent point and I feel like I failed the developer community in some small way when you had to bring it up. You shouldn't have to provide a reason for wanting progress, it should happen for its own sake.
Proceed.

I'm not trying to start an argument at all but you have to think broader mathematically. If the processor runs at 1000Mhz or 999mhz (In the case of my N1) a .267 increase is 267mhz, a 26.7% increase in computational performance... That's pretty raw especially in cellphone terms, that have no way to vent or displace that kind of heat.
Has anyone noticed how much hotter the kickstand gets? I bet you that it's attached to something the cpu is connected to. $5 bucks says we will see KICKSTAND HEATSINK + FAN MOD 2GHZ OC! LOL

This is a patch for developers, not a discussion thread for the merits (or lack thereof) of overclocking.
If you don't want to overclock your phone, nobody is making you.
It has worked out fine in the Desire and Nexus One community.

need to follow the directions in the first post. the .c files need to be loaded into the kernel source (right now just have toast's soruce) and the kernel has to be compiled with them.
if somebody wants to compile up a kernel with these, we could start testing. if i get some free time i'll help out here and compile a kernel but somebody else will prob beat me to it!

please someone let us know how this works out for your evo 4g... benchmark, test results... anything to show better/worse performance, whether your got ALOT warmer, or just a lil, etc.. ne information would be greatly appreciated it, i'm not a 100% noob, i just know how to follow instructions very well, doesn't mean i understand everything that's going on, just the basic concept of what i want. thank you in advance.

I'm waiting for someone to compile this first.
If nobody steps forward, I'll make my own attempt, but I'll be working blind with no test hardware.

I'm pretty sure most devs are waiting on the htc source kernal before playing with this. I can't wait but I understand them being hesitant to do too much with this for now. Still awesome of you to post it and have it rdy for when that time comes!

Your signature says you have a radio of 1.32.651.6, just to let you know that is not a radio, that is an HTC software OTA update. My radio is 1.39.00.05.31 for example

SetCPU for Android

I'm sure almost all (if not all) of you that have obtained root on your Incredible (which this app requires) know what this app is and possibly have even used it in the past. There doesn't appear to be any Incredible specific modifications made to the app yet, but I just wanted to throw this out there. As always, be VERY careful with overclocking, esp. with this CPU (I personally wouldn't try anything over 1.2ghz). If you feel your phone getting hot, don't keep running it! Also neither the author, XDA or I take any responsibility in the case that you toast your Incredible.
http://www.pokedev.com/setcpu/

I thought we'd need a modded kernel to run it over 1.2 Ghz? How can we do that with just rooting the phone and installing setcpu?
Or I'm way off and I have no idea what I'm thinking lol..

no, you are correct. i have built the kernel (HTC release) w/ the required changes. but have not been able to flash

Wow I wasn't aware of the kernel limits, or maybe I subconsciously read it somewhere since I threw 1.2ghz out there (over the last couple weeks I've been dealing with a cold I can't seem to shake so I blame a combination of insomnia+Nyquil... mmm Nyquil).

Id say its worth some green to get that kernel. I have been looking high and low to find one. seems that the demand is there but not the development. Let me know if you get it up and running and I'll donate to the cause.
Just wish I could develop it at this point, but getting the phone rooted was a task for me. Even with video instructions....

[Kernel] [Updated 22OCT] HeroC - 2.6.35.14

This can now be considered stable, after significant testing and use by the community. As always, the hero you save could be your own, so be safe.
This would not have been possible without the efforts of everyone in the community that played a part in moving the ball forward. In particular s0be and riemer for their initial efforts to get a working 2.6.35 build as a baseline, and the continuing efforts of riemer, erasmux, arco, et al; also thanks to toast, darch, decadence, pershoot, and cyanogen, as well as the Linux, CM, AOSP, and CAF teams that have provided the broad shoulders for tinkerers like myself to stand on. My sincere gratitude to all of these and the legion of others who I have not listed, who have contributed to making the open source community strong and productive.
This kernel is based on a combination of updated board files for HeroC, and efforts by arco, riemer, erasmux on new sources originally from the HTC marvel code release. After several weeks on the new base, everything appears to be working well. Initial sources have been posted to github.
New version (2.6.35.14) is at:
https://github.com/TeamHeroC/heroc-kernel-2.6.35
The sources for this Kernel and the AOSP flavored 2.3.5 ROM sources are posted to the TeamHeroC github. This organization github was created instead of using a personal github so that others could join in team development efforts if they are interested, and the organization could be more easily maintained after people move on to other devices. I am probably looking at somewhere between 2-5 months myself.
Flash from recovery, and remember nandroid is your friend.
UPDATE - KERN-2.6.35.14-10SEP-V1.0.zip
10SEP version has been updated with changes from various sources. Github has also been updated to be in sync with this update.
UPDATE - KERN-2.6.35.14-22OCT-V1.1.zip
22OCT version has been updated with changes from various sources. Github has also been updated to be in sync with this update.

Old version - No Longer in Development
This is very much a work in progress, so be safe.
This would not have been possible without the efforts of everyone in the community that played a part in moving the ball forward.

My sincere gratitude to all of these and the legion of others who I have not listed, who have contributed to making the open source community strong and productive.
This kernel is based on a combination of the s0be/riemer board files and other mods applied to the CyanogenMod cm-kernel android-msm-2.6.35-unified branch. It does not have smartass (not working yet), but the camera seems to work consistently for me on both interactive and ondemand (Note: setting min cpufreq to 352 is recommended to minimize camera problems). This is still very much an early effort, but thought I would post for anyone interested. Initial sources have been posted to github.
https://github.com/TeamHeroC/cm-kernel-heroc
New version (2.6.35.14) is at:
https://github.com/TeamHeroC/heroc-kernel-2.6.35
The approach to building this kernel was to go back to a build based on the last CM 2.6.35 source from the repo and add files from the s0be/riemer source tree to get a working kernel. My goal is to get this as close to standard source as possible, so the changes will just be the device specific board files, drivers, etc. The reason for this approach is to (hopefully) get a well defined set of files and updates that can be applied to other kernel releases (.37, .38, ...) with minimal conflicts and dependencies.
Lots of things that I will be working on as time permits. In no particular order this includes things like:
complete headset updates
update qdsp5_comp to align with latest sources
update smd files to align with latest sources
rework board files to current standards
check and complete i2c updates
complete USB updates
compare and update MSM frame buffer files
cpufreq updates and smartass governor
check and update device specific drivers
The sources for this Kernel and the AOSP flavored 2.3.4 ROM sources are posted to the TeamHeroC github. This organization github was created instead of using a personal github so that others could join in team development efforts if they are interested, and the organization could be more easily maintained after people move on to other devices. I am probably looking at somewhere between 2-5 months myself.
Flash from recovery, and remember nandroid is your friend.
Added No Headset version as suggested by s0be. This version has no headset drivers built in. In theory, this should improve the stability of your USB functions. This has had very little in the way of testing. YMMV.

One question, Ive been running the kernel that you posted on s0be's thread a few days back, is this one updated or is it basically the same? So far no Camera bug for me (which is why I flashed to begin with).

A few changes since then, but nothing major. I can't really say whether it is better or worse than the previous. Seems about the same to me. I will add the previous version to the OP later as well.

Radical.
Thanks for your efforts. The previous version has been working well for me on your May 30th rom with FR 118_15 with some autokiller tweaks. Battery life seems a little worse but still very decent. All very smooth with ADW eX and LPPro . Had a couple of issues with the phone locking up (black screen) for about 20 30 seconds, then coming back on its own. Not sure if it was because my min was too low on setcpu (on demand). Not that it matters but my linpack scores have been consistently lower. but real world performance is great.
Lets see how this does.

so totally didnt see this thread until just now.. thanks a ton jaybob.. this kernel has some loyal followers, and i know i can say for most of them that i am glad to see someone who is capable pick this up.. i was trying my hand at it, but i dont have the time right now, and my knowledge base just isnt as broad as it needs to be for this.. so thanks man, you are the best..

3 Hours now and it seams stable. It took a little while after the first boot before my phone became stable. The ROM I am running the 5/25 version of Evervolv.

No perflock in this kernel (or s0be's or deca's). My recommendation is just based on an observation that when the min cpu freq was set to a very low value (19), I would see a lot of camera freezes. It may work fine at lower settings, I normally have mine set to 352 and don't have camera problems with ondemand or interactive, so this is just what has worked for me. It may also be fine at 264 or 176, but I haven't tried them.

Running this kernel with the latest CM7 nightly and I've never seen my Heroc run so smooth nor get this crazy good battery life.
Thanks JB.
Haven't checked to see if I get my regular reboot after 10 minutes of Google navigation.

I was using sobe's .35 kernel and the camera worked at first but lately wouldn't work at all and I saw that the camera was supposed to be working well with this. Flashed it a little while ago and haven't been able to take a single picture. My cpu is ondemand with a min/max 518/768.

i honestly think that right now some of the camera stuff is phone specific.. because i know some people have no issues, asome people have intermittent issues (me), and some people lose it all together.. but thats how it was with s0be's version as well, i think until most of the camera bugs are squashed we will continue to see random issues for random people..
BTW since you already cant use the camera, try switching to interactive for the governor, and try it then.. jaybob said that his works fine with interactive, so maybe your phone will respond better with it.. just a thought, no promises..

352 min cpu fixed my camera issue.

overclock area on cm9 greyed out

Why is the overclocking area on my Captivate greyed out after installing cm9 latest nightly???
I honestly do not have the time to read hundreds of pages of forums to see if someone has allready had this issue.
Of course i tried searches.
It happens on any cm9 nightly, not just the latest one.
I want to be back at 1.2ghz. being stuck at 1ghz. is rediculous to me after being so spoiled. (lots of google earth, gaming and other stuff that a higher clock speed helps with)
If I have to I will just go back to 2.3.7 and a swift 1.3ghz. MAX
BUT it seems like I should be able to overclock using CM9 on my captivate.
Please do not explain the system settings and performance yadda yadda yadda, anymore, i am obviously familiar enough with an android device to know how to use system settings etc. if i can root and install custom roms i can read and point and click as well.
Sorry for the frustruation but i seriously can not deal with anymore nonsense and 80 diff. pieces of broken info from people that only "heard from some guy" about how to do all this.
Thank you in advance... forever learning"!"

Were you using Glitch before, or some other custom kernel? I didn't think cyanogen's stock kernel supported overclock. If you install a new nightly you have to reinstall your overclocking kernel.

I have been using cyanogenmod only. I never purposefully installed a custom kernel then the rom. Just used Odin to root/clockwork and so forth. Never heard of Glitch. Through out all of my custom rom experiences with the captivate I have been able to use the sys. settings or osmonitor to overclock to a max of 1.3ghz. I have tried miui or whatever its called for about five minutes. other than that just cm6/7, then updated to cm9. in the past whatever kernel i had, stayed in effect, i guess.
I will do a search for custom kernels for cm9 on captivate.
I havent seen any yet, but who knows. I am used to simply stunning roms and the moto droid one. That was great! SS/chevy~ would always have links to the latest kernels avail. for the current builds etc. Good job too.
SO... the search continues.
*Mystery: If I cant even change cpu settings in osmonitor (up or down), yet it lets me enable root mode, what does that mean? The greyed out overclocking area in perfomance settings (up or down)???
I need to learn more"!"

As mentioned, glitch kernel b6 is a great ics kernel. Flash over CM9 and install nstools from the market to control all the kernel settings such as oc/uv, voltages etc etc.
Sent from my glitched ICS Captivate using XDA App

The options are greyed out because the stock kernel currently doesn't support overclocking. Glitch is awesome, and Semaphore kernel is pretty nice too.
Sent from my CM9 ICS i897 Captivate

IcyGlitch for OC, and Semaphore for 400MB mem.

Well Glitch has 387 MB of free RAM

both kernels are good
I want my 13 MB! They are unused so occupying them is unforgivable. IcyGlitch is solid kernel, and I hope 400MB will be added.

[Q] Need root/rom/etc recommendations for an odd Captivate setup.

I just picked up this OEM-condition ATT Captivate today and after playing around with it, installing apps on it, fixing the rear speaker, etc...I decided I want to root it and try out a good/reputable/reliable ROM.
Here's the tricky part...this phone doesn't have service, nor will it ever. That's right. Absolutely no cellular service for this device. I'm using it strictly as a home phone for incoming/outgoing calls on my WiFi using GrooveIP + my google voice number(and maybe some games/radio/etc) and as an emergency phone when I'm away from home and in other WiFi hotspots. Otherwise I've got this crappy little tracfone that I use almost exlusively for texting and the rare phone calls I need to make. Just can't justify wasting money on a contract or any other setup with the way I use phones anymore.
So considering how I use this phone is it worth rooting? If so, what ROM could I go with that will be significantly better than the OEM setup but not require j33t hax to mess around with? If this were my main cell I wouldn't mind going all out on it like I've done with every other phone I've owned, but since I use it this way I can't really justify dumping a ton of time and effort in to it. I just want something clean, cool, and reliable.
If it helps any here's the apps I have/use currently...
-Advanced Task Killer
-Play Store
-Zedge
-Firefox
-Youtube
-GrooveIP
-Gmail
-Facebook
-Words With Friends
-AdAway(Don't use it, but would like to)

Check the development forum. Someone created a ROM called captivate touch. I think it is what you're looking for.

Thanks for the recommendation. I'll check that one out.

Check out Legend 5. It's the best for KK4 Gingerbread (Tested by me).
The link is on my sig just click it. :good:

Thanks, checking that out now.
The ROM mentioned by a poster above doesn't look to be supported anymore and I don't think it's compatible with my KK4 GB.
Could someone explain to me real quick how this ROM stuff works? To my knowledge this phone has a Firmware and an OS, and if that's the case, does the ROM replace the OS and/or the Firmware? Or is it installed and ran separate from my Firmware and OS? If there's a thread that explains this, a link would be much appreciated.

Answered my own question. I'm going with the Legend 5 ROM + CORN kernel 7.06 using the Odin method. Installed the kernel first, now trying to figure out how to get the pop-up menu when I plug the USB cable in so I can go to mass storage mode in order to put that ROM.zip file on there. I guess it doesn't do that anymore with the new kernel?

Install went without a hitch. Noticing a lot of visual differences, but not much in the way of performance differences.
Does this CORN kernel lock my phone in at 1.60GHz or did I misread something?
Does having this kernel mean my phone is now "rooted?"

Corn kernel gives you a ROOTED status, and enables you to use "schedulers and governors" and a 1.2Ghz CPU speed which is confirmed safe. Download CPU Spy and Voltage Control in play store so you can monitor your CPU usage and can adjust between schedulers and governors. I use Legend 5 ICS.

Not sure if I want to go as far as OCing anything. Just looking for a nice ROM that fits my needs.
Legend5 seems nice but it has some issues here and there and the way I use the phone doesn't really benefit from a majority of the changes it offers. I'll keep messing with it and see if I can like it a bit more.

takeoutttt, I got CPU Spy and Voltage control but what I'm seeing on my screen doesn't match any of the walkthroughs I found for VC.
On the main screen I have the Scheduler dropdown, Governor dropdown, and two slider bars...one for minimum speed and one for maximum speed. I see no other dropdowns, no other sliders, no advanced screen, no voltage controls, etc.
Options in scheduler dropdown; noop, deadline, cfq(default).
Options in governor dropdown; conservative, userspace, powersave, ondemand, performance.
Settings are default for now until I can figure this out.
