[KERNEL] 1.6ghz - For Android 3.01

06-19-2011
The above has a max clock of 1.6ghz.. It has all the regular features included prior to this release - underclocking when it gets too hot.. various non-cpu overclocks and so on.. and unlike previous kernels.. its pretty damn stable.. I've tried to crash it. I can't.. Help me crash it. Don't help me crash it if you're on 3.1 - because this won't work with 3.1.. Ok? alright then.
#older stuff below
This lovely little kernel has a max of 1.646 (because 1.7ghz will run for about 30 seconds). But it also has been setup to set the max clock to 1.2ghz (temporarily) when temps get above 42 deg C.. For people using setcpu, I do not know if it sets only cpu0 to the desired freq (and presumes cpu1 will follow).. but it seems that you need to set both to the desired freq, otherwise it'll use the higher of scaling_max_freqs (cpu0,cpu1 - thus two scaling_max_freqs) and ignore the value you just set.. doesn't make sense? yeah.. ok..
if you set cpu0 to 1504
then you set cpu1 to 1504
then you set cpu0 to 1000
... scaling_max_freq is set to 1000 for cpu0, yet cpuinfo_cur_freq will show higher than that (under load obviously)..
just based on my experience.
Just because the max is 1646... doesn't mean you should complain when/if its unstable.. Well, you can.. but you really don't have to.
This is for 3.01.. Im not sure I trust 3.1 yet. ..
Here.. this has sys/avp/vde/gpu/pclk and of course cpu, overclocked. I ls'd the modules directory for you and got this..
bcm4329.ko cifs.ko ntfs.ko scsi_wait_scan.ko tun.ko
I don't know what it means.
If you have problems with netarchy's kernel and you don't with this.. You're probably insane and making stuff up...
This not my first compile. I run my own custom kernels on Gtab, xoom, G2, and HD2.. All pretty spicy with the overclocks..
This may cause some incontinence.. only some.. its ok tho. perfectly natural.
this is the first time I've posted any kerzanels..

I'll give it a go.
Right after I nandroid.
And flash the new CWM >_>

Have you got a link to your source code ?

DAMN!!!! very nice

would love to see some benchmarks and improvements reviews

Well, I flashed this on my TF earlier today (running Prime 1.3r2)
I got Linpack scores of 63.3+ and a first run Quadrant of 4339. However, my device froze 3 times within half an hour of flashing it. I cleared the cache several times pre and post flashing. My device even froze on the initial boot after flashing the kernel, so I guess it isn't a thing of speed instability. There must be something else. I will try to reflash it later and see if this behavior continues.

Not really. The init.ventana.rc script within the ramdisk sets the max frequency to 1.4 - so if there were freezes in android, there could be freezes when android starts to boot - roughly around the time adbd starts... Are there any kernel logs (ramdump files on your internal "sd")
Strange how it would run thru benchmarks, yet be unstable. Was this at 1.504?

Yup, I set it at 1.504 and it allowed me to run Linpack a few times before crashing. Quadrant allowed me to go 1 full run and about 1/3 of the next before it crashed. I found a ramdump.log file in there. Is this the one you need?

@Blades,
Here you go...

Definitely will try this after work today! thanks for the new kernel!
HTC Thunderbolt & ASUS Transformer Rooted!

wow, what a crazy kernel

Thanks I'm going to give this a go with the modaco rom

Is there a way we can schedule the 1.5ghz to kick in? seems like it crashes few minutes after boot because some other app are still loading. I've set my setcpu to 1ghz max and reboot, everything loads perfectly then after 5 minutes i revert it back to 1.5ghzl, overnight my TF doesnt have any problem.
This morning i restarted my asus just to experiment if it will boot normaly while im in 1.5ghz max and 200+mhz min. It crashes few minutes after reboot.

45 minutes of Pocket Legends and no signs of slowing down at 1.5GHz!

I believe high profile HD video performance is more an issue of HC 3.0 not taking full advantage of Trega2 hardware acceleration and until HC 3.1 we won't see much improvement. Overclocking will only help so much...

Updated:(3/6/2011) Lets Solve G2x Freezing Issue (Solved:Random Freezing in standby)

I know there are countless threads related to G2x Problems but none of the threads are focusing on isolating the reasons of Freezing Issue. I have recently upgraded my phone from Galaxy S Vibrant to G2x and i have to say i love the hardware and performance. Only Issue for me is random freezing.
After using the phone for 2 weeks and trying 3 roms
1. Stock
2. EB 1.04
3. Dark Sinister 1.1
I have come to a conclusion that kernel and rom is not the solution. At least not for me.
So i will try to solve the problem using hardware testing.
From my past 2 weeks experience.
1. Phone Freezes at night during charging
2. Phone Freezes when ever i turn off/on wifi and bluetooth and gps and Data (4g/3g) (Still have to figure out which of them is the cause. Cause i usually turn all off when i need to save battery).
Test Day 1
For Reason 1
I am using SetCpu and have changed Min from 216 to 312Mhz. I am trying this because i think very low cpu usage in standby for a very long period causes the phone to freeze. Its a Hunch i am not sure.
For Reason 2
I will keep wifi, Bluetooth and GPS off.
I will keep 4g/3g Data On all the time.
To My Surprise its been 16 hours no freeze. It includes charging at night. Lets see how long i can go without a freeze. Upon freezing i will make some changes.
Update 31/5/2011 (Test Day 2)
Ok its been more than 40 hours and not a single crash...
I removed the following possibilities as well....
It wont crash upon excessive usage.
Also Normal Heat up does not cause the crash.
As i have been playing Samurai II Vengeance all day long... Until I ended it. Several times charging along playing. I even played it on TV using HDMI. Not a single crash. I used to have around 3 crashes a day on stock rom when i unboxed my new G2x.
I also started using GPS from today. So lets see how it goes. I will update it every 24 hour.
Update 3/6/2011 (Test Day 5)
Ok i am considering Random Freezing On standby as solved because i havent had a single freeze at night after setting CPU Clock at 312 MHz using SetCPU. There are also other comments that back up my solution. I am considering this the solution of one problem.
2nd Issue of freezing while using cell phone apps is because of certain applications that are either buggy or not compatible with tegra Platform. For that i will start another thread with individual application testing for all apps that can cause the system to freeze or crash.
Please Discuss apps System Bloat-ware/User Apps that cause your G2x to Crash or Freeze in the following thread i created:
http://forum.xda-developers.com/showthread.php?p=14399089
Thanks for all the feedback.

Luckily I dont get that issue, buy I think this is a good test :u

Good point. I have not had these issues but i do have trinity kernel and minimum speed is 300
G2x with CM7 and trinity kernel

All you have to do is be careful what apps you install. I've had the phone for over a month and the one time it rebooted or froze was when I used an app the phone didn't agree with.
I am almost certain that people are experiencing reboots and freezing because of the apps they have on their phone. Hopefully the update will solve the problem because it shouldn't be that way.

In my opinion, the shut down has to do with temperature of the phone. As long as I keep the phone cool by not charging and multitask with other things, then my phone is fine.

I used to think the same thing but the problem is my phone gets hot and works fine. I am almost positive it has something to do with an issue in the kernel that's being exposed by certain apps. My Xoom on release had reboots and SOD and it went away with app updates and removals. It also has Tegra 2

Do you or @kangxi remember what Apps gave you issues?

it has to be a driver issue, its virtually the only explanation for why devs have not hammered it out yet or even CM7 team for that matter... it has problems on pure AOSP which leaves drivers or overheating (unlikely)... LG has to come up with the fix because they know their drivers and hardware better than everyone else...

Well the obvious problem I see is that they are all based on the stock rom. Try using one build from AOSP or a CM variety.
I didn't stay stock long but I did have reboot using the leaked Gingerbread (which is what EB is built from). I don't follow it but one is based off the stock 2.2.2 rom and the other is based off the leaked 2.3.3 rom.
I had nothing but problems with the stock roms. Thus your problem I think. Move over to Bionic, CM7, Gigglebread, or something.
I tested my phone and I didn't have a reset in like 5 days (which then my battery died overnight because I forgot to plug it in). I usually crackflash the CM nightlies and haven't had any problems with reboots or any issues requiring a reboot (aside from the flashlight killing audio, but just don't use it).

There are definitely two problems - software and the battery. I used to way more problems until I exchanged the battery for a new one and that solved most of my issues. The issues that remain are definitely software based.

Thanks for this information/ Changing the minimum speed didnt affect the battery life but it has survived two nights without crashing. So i am planning to keep it at 312Mhz min.

I Completely Agree with you. Some Applications do cause system crashes. But I have removed all the t-mobile bloatware and i only have few games and GPS apps. All games are from tegra zone. So I am sure they are supported.
For GPS App i am using Copilot and it didnt crash on me once.

I just installed setcpu and set minimum to 312. I'm keeping everything else the same to see if this change has any difference. Will report back.

Looks like you are gaining progress. Sounds like keeping the processor revved up a little more does the trick.
It would be a simple fix for people to try that have reboot issues. I can't get mine to reboot, so unfortunately I cannot help you. My contribution was to resist from flashing for as long as possible to test how long I could get my "uptime" to. I got up to 127 hours when I passed out without charging it.
I'm running 20 hours now because I forgot to charge it again (seems to be my only problem, lol).

Looks like you may have fixed your rebooting issues. It sounds feasible that the clock speed could be causing it. I never had a reboot so I can't help you out but I can tell you that I have a profile under SETCPU that clocks it at 216 min and 216 max when the display is off and I don't have a problem. I wonder why the low clock speeds would only effect certain devices? Maybe it's certain apps that stay running in the background (since there poorly written) that require higher clock speeds than what the G2X gives at idle?

I've definitely noticed that the G2X wakes up faster and smoother (fade in from screen off) when min is set to 312mhz that's for sure. if this is all it will take to stop the reboots, I'll be super happy because otherwise this phone is just amazing.

Have you noticed any changes in battery usage? I haven't really played around with SETCPU much but can the clock speed be set lower and if it can, have you tried slightly lower settings than 312mhz?

y are u guys using setcpu? and its def cuz the min is too low faux has his at 400 and no problems morfic also has his a little higher then what is it i think 216?? thats too low thats y setcpu isnt supported yet.....pimp my cpu

Someone asked me a question earlier. Only app I had issues with was fring. Soon as I opened it and started playing around with it, phone rebooted.
I uninstalled and it never happened again.

No clue what you're trying to say but setCPU works fine. At startup for first time I selected Tegra2 and it works great. I have max set to 1000 and min to 312mhz (default was min to 216mhz). I'm running stock ROM but with root. that's all.

well thats y it works for u, u cant overclock over a thousand mhz so in ur situation ur ok i guess it only applies for people running a custom kernel then setcpu doesnt work, then u would need pimp my cpu

Overclocking Nexus S with Oxygen

Hello all,
I just flashed the latest Oxygen on my i9023. I noticed some good improvement when I set the max clock speed to 1200 or even 1400. Thing is, I want to use this phone for atleast the next 1.5 years and so don't want to wear the processor or something.
I have not suffered any problems or reboots even while running at 1400. Any advice on the safety of overclocking? Also, how do I know if this is overvolted?
Thanks

On the overvolting/undervolting thing, you might wanna give proton voltage control a try. it's developed by xda member jonathon grigg and you can find it on the market. From the app you can see what the stock values are as well as over/undervolt yourself.
can't help you with the overclocking bit though sorry

I wouldn't worry to much unless the phone gets extremely hot or shuts down alot.

[Q] Overclock/Underclocking questions for Droid 2 Global

I recently took a big step and rooted my D2G (had a bad expeirience last time when i rooted it and flashed a rom). ive read alot on overclocking and underclocking and have learned most of the basics about it but still have some little questions im unsure of. Btw i use setCPU with no roms or different kernals or any of those things. (btw im a noob when it comes to phone tech and stuff so be nice to me plz)
1. How do i overclock my phone past 1.2Ghz? I read that only certain kernals allow you to overclock past 1.2. If so does that mean all i have to do is install a different kernal or what? i was also reading about CM7 and was thinking about flashing to that to see what it does. Does CM7 come with like a different kernal when you install it that allows you to do that or what?
2. What are the risks of Overclocking/Underclocking. I know that overclocking lets makes ur phone overheat alot faster and that can easily damage the phone but other then that does it hurt ur phone in other ways? also what would underclocking do? I read that it can make ur phone a little laggy and can possibly freeze it but i read to fix that all you need to do is pull the battery and start it up again which doesnt sound that bad.
3. how far can i underclock my phone to where i cant use apps or surf the web. The one reason i ask this is because this summer i will be going on vacation and am going to be taking an airplane. to pass time on the plane i planned on putting a couple of movies on my phone to watch but i fear that this will drain my battery realy fast. what if i were to underclock down to 300Mhz and then play the movie? would that save me any batter life at all and what would happen to the movie? would it still be able to play fine or would it be all jumpy? Would i even be able to play an games on my phone with it underclocked that much?
Sorry if any of these questions have been posted in other threads before, i searched for a couple days and tried to do as much research as i could on my own before coming here and asking. Many Thanks

so underclock and see what happens, not that hard, really depends on your phone
if it doesn't run smooth @ 300 bump up to 400 or 800
takes 2 secs

I would recommend quickclock, it's in the market and fully supports the d2g. It allows you to run a calibration test and determines stable oc and uv. I use it on my d2g and dx.

Music stutter/lag when screen is off LG Optimus P920

Hello there fellow members,
First of all, the thread's title is for SEO purposes only so if anyone else runs into the same problem with this phone and start Googling for a solution this will come up.
The issue I have is really basic, I went through all the threads but I couldn't find a trivial solution for this. So I flashed my P920 (again) with V30A (it was a nightmare with all the unbricking process and whatnot, lol) everything is fine except one thing. This is when I play music and turn off the screen it starts lagging almost immediately. I am pretty sure it's about the CPU clock speed scaled below to 200Mhz or something, but I can't figure it out how to change this.
I have downloaded Trickster Mod but there are only two options I can set; the min and the max CPU speed. I've tried other apps as well, no luck. There's no option to set the CPU frequency when the screen is off. Sure it's a good way to save battery but really annoying when it comes to playing music.
I'm not sure if it's the ROM, maybe the kernel (i'm that kind of guy who can make these things work but I have really no idea what is really going on with linux based systems)
Here are my system specs;
ICS 4.0.4
OMAP4430/XMM6260
Kernel 3.0.21
P92030a-EUR-XX
I also have TWRP recovery installed and full root access on my phone.
I appreciate if anyone of you can point me to the right direction what to do with this.
(oh, one more thing please; let me ask you a bit off-topic somehow according to this; ever since I upgraded from Froyo, somehow I feel this fantastic phone a bit slow. It's not as responsive with ICS as it used to be with Froyo, I don't know I would say it's something like when you have a fairly old PC with WinXP and it runs pretty well but once you upgrade it to Win7 it's still okay but not that "lightning fast" when it was with XP. So yeah, maybe it's the old hardware - new software case that I'm "feeling" but 2.2 was definitely better (in terms of speed) when these latest operating systems available for P920).

Just Try flashing a custom kernel!
