Over Clock Kernel - wifi error

I am running CM6 A013 with oc-legend-cm-2.6.29.6 kernel. Everything seems to be working just fine except for the wifi. Has anyone gotten the wifi to work with the oc kernels?
I read in another thread that we could take the wlan.ko file from an old ROM. Does anyone have a copy of this file or would anyone be willing to pull the file so that I can test it? I really appreciate it.

same situation here. neither kernels work with cm6's wifi and hotspot. can someone fix this please! i really want my wifi back! i didnt do a backup before hand!

Im looking at this and it looks easier than just replacing the entire kernel like you guys did, read here from that guy's post above:
"How to do it for kernel_legend_13be9c9c:
At first, you should read zanfur's post and his patch.
I just modified two tables in acpuclock-arm11.c excluding his having written.
1. modify cpufreq.c to let SetCPU to access freq tables
2. modify acpuclock-arm11.c to let HTC Legend be able to overclocking
3. modify msm7227_defconfig to disable PERFLOCK [optional]
You might not need modify defconfig when you use SetCPU which can purchase in Android Market.
SetCPU can disable PERFLOCK by setting. ([menu] -> [Perflock Disabler])"

So, with that said, I would take that file or file(s) and replace them with the ones in our current kernel made for our phone... might work and your wifi won't be broken.

You guys are running a kernel made for a different device.

could some one say in plain english the exact steps to get the old kernel back? the one from CM6

That kernel is not built for our wifi chip. The kernel needs to be built for the BCM chipset and not the TI. Further, the wifi module needs to be in sync with the kernel build. Android 101.
I am not sure what we are going to gain from overclocking. There just doesn't seem to be any end goal, other than bragging rights on a benchmark where the Aria can only hope to be among the best of the mediocre CPUs. If it's for flash - forget it. We don't have the instruction set required in the CPU. The downside is the potential to add instability and confuse test results for mods that can actually increase functionality.

I like overclocking and running a couple benchmarks once in a while. For day to day use I'm more interested in downclocking but only if it can increase battery life.

the extra speed of the OC makes a big different on the games, that's the reason I like it... Games run smoother with the OC kernel.... do the test.. try to run Abduction with the stock Kernel for a while and then with the OC.. you'll see the difference... also Live Wallpapers with the stock kernel is choppy... it is smooth with the OC.

Hell my nexus one has been over clocked since the day I got it (rooted that same day ) not that a 1ghz phone really needs it. Well the Nexus One maybe for gaming but my Captivate and Vibrant on the other hand doesn't need it period. You won't get better performance gaming with any other android handset out there to date. Still my Captivate is over clocked to 1.2ghz lol. Like I say there's something fun about pushing the limits.
It really just another thing to tweak and play around with on your device. It's always fun to push the limits.

There are several reason why I would like to overclock. 1. The 3D photo gallery loads photos really slow with the stock kernel, but with an overclocked kernel the pics loaded very quickly. 2. It's nice to run a 3D game or two without chopping. Just to name a couple. It would be nice to have an Aria kernel that works with all of the phones hardware. And showing off benchmark number is nice as well.

SetCPU no longer underclocking at low usage?

I have moved from CM7 to Hombase 5.4, and found that setcpu no longer seems to do anything. on CM7 it worked as i had hoped, underclocking the phone when i was doing low intensity stuff like texting, and pushing it up to full power for videos etc. now it does nothing but tell me core temps, which are always high as its always running at 1Ghz.
Can anyone explain how to get it back to underclocking?
Many Thanks

Try a different kernel.

This is a known issue with the OC faux kernel. I was running into the same problem with his enhanced stock kernel after using webtop. After reflashing the enhanced stock 0.2.0 it would still get stuck at max 1Ghz after using webtop, but a reboot would get the underclocking working again.
I only tried the webtop hack to see if I could get it working. I haven't gone back into it at all so I don't know if this is something that will reoccur. Although I will say that with my day to day use I have not run into any clocking issues since.

Thanks, is there a page somewhere which details which kernels do what and which would work with my rom?

This is the page for faux's kernels. As far as details, start reading and searching through that thread as well as the threads for any ROMS you are using. 99% of the time people will either have the same problem (and possible fix), the other 1% of the time they will identify a bug (i.e. maxed out CPU).
Keep in mind faux does have different kernels for Froyo, GB, and CM7.

For some reason even if I move the slider from 1300my to 1000, when I touch the screen with at least 3 fingers for a few seconds it pegs out at 1300. I read our cpu's are daisy chained so to speak
so the 2nd core kicks in when needed. I tried cpu tuner and it gives the option to powersave and only use one core or if you choose performance it will allow Both cores. Just might be setcpu isn't designed fully for our dual core setup.

thanks for the link to kernels, but i cant find one for HomBase, or a Kernel only download on the homebase thread. i have the Version2, which has some blur, but only the 1.0Ghz clock kernel. where could i get the 1.3GHz download by itself, to see if that might help, as its the one CM7 had iirc
Thanks

Get the 1.3 from the faux thread that I linked to. They're in the very first post...
CM7 is the only ROM that has its own custom faux kernel. For all other ROMS just match the kernel to the build the ROM is based off of (Froyo or GB). If you're using V.2 of Homebase then use the GB one.
Update: Also, there are other kernels out there. I was only using faux's as an example since you were using CM7 and Homebase.

thanks, ive now got the 1.3Ghz kernel installed successfuly, but it still seems like setcpu will not underclock. i dont know if its normal, but the "Scaling" option is greyed out, and i cant get access to the Advanced tab. is there something im doing wrong in setcpu itself?
thanks again

Lack of underclocking is a known issue with the latest OC kernel. I'm unclear whether it's actually a bug with the kernel or with setCPU not supporting dual core devices. But yeah, there's a problem with it right now. I'm on the stock enhanced, and other than the webtop issue I mentioned above, it works fine.
Scaling/advanced are not available, this is something that is determined by the kernel you are using not the app.

ok so if i understand you right i would be best off using the stock enhanced kernel (for now), as it will underclock fine?

It's working perfectly for me, except after webtop use (which I don't normally use).

I'm still having the same issues regardless of weather I choose power save or performance it will not underclock, and those are the only governors I get the option of :s

User feedback

So I've got some time at the moment to work on the vibrant again, so I figured I'd ask you guys a question.
What are you guys wanting out of the vibrant?
I'm not really one to go for the latest and greatest buzz word feature like "Linaro build" or "optimized build prop," etc.
lengthy posts are encouraged, tell me what you still want out of this device. What do you use it for? What do you want to use it for? Etc.
Like I said, not looking for "gimme 500MB ram" or " an updated 2.3 kernel", I wanna know what user experience your looking for.

Point if the question was missed, it's not about faults. Also there are very talented individuals working on the GPS issues. I cannot test GPS as mine no longer works. I want to know not just for me but also the talented Devs working on the vibrant, what ideas do you guys have for improving the Android experience, just in this case I happen to be gearing it toward the vibrant as I won't be working in anything else myself. That doesn't mean it's faulty, there is always room for improvement.
Anyway...not monitoring this thread anymore....Idgaf anymore and people not gonna answer :3

ECOTOX,
Just in case you do monitor this thread Ill give you a request. Ive built a couple of Froyo ROMs now, and plan to stick with Froyo for some time (at least until the EU error fixed)
That said I usually package the Bali 18.8.UV kernel with them. My favorite Froyo kernel is the DMZ kernel.
http://rootzwiki.com/topic/633-kernel2213ghzdragonmodz-nightly3smartassscary8262011140pm/
What set your work apart is the fact it could stepclimp in 100mhz increments. My phone pukes at anything over 1100mhz. Its has the smartass governor (the one I want) that works perfectly. It is smooth, quick, and almost perfect for my needs. Ive only packaged it with one of my ROMs due to the lack to stepclimbing. Here is a request:
Ive tried up to 3 different overclock / volting programs. Tried to set it manually via init script, but the kernel has 2 stock settings: 500mhz / 1000mhz. If I I overclock to 1100mhz I only get three settings: 500/1000/1100. Is there any way you could get a 200mhz in there?
That said your git is available. I don't know how but I guess I could try and build my own based off your source / patches. You kinda sounded like you wanted to help/work some on the T959. With the EU error we have more folks coming back to Froyo every day. Froyo is not dead if I have anything to say about it -
Thanks for your time (I if read this)

GPS is primarily due to inadequate or faulty hardware design. We have pushed the limits of trying to fix it with software guys.

I personally would love more battery life. I truly cannot get more than 45 minutes of screen time in ICS.

Lol happened to be browsing the forum for info and saw you posted here.
I'll make you a kernel, but I'm not 100%sure I'm sticking with the 100mhz steps for my own release but I'll make you one specifically. I might, but I want to get voltage control working with 100mhz steps, I also gotta work on keeping the gpu clocks more stable.

I would be in your debt sir. Thanks for your time.

I just wanted to say thanks for the great work on DMZ, ECOTOX. It has surpassed Overstock as my kernel of choice, but I had one quick question/request. Is it an issue with the kernel or with a particular ROM for some functions to get a little quirky when you start to overclock into the 1.2Ghz range? Whenever I set the CPU ceiling to 1.2Ghz the long press functions on the haptic buttons of the Vibrant would become flakey. I read that's fairly common with overclocking, but was curious who the culprit might be.
Not knowing anything about how scalers/governers can be implemented, what would the chances be to get something like Smartass v2 or a few more options on a new Froyo kernel? I liked messing around with them when I was running Sub-Zero on ICZen to find that happy medium of battery life vs performance.

I say a Galaxy S III themed gingerbread ROM. Anyone?

AOSP roms will ever reach (or overreach) stock roms battery life?

...or it is impossible without Samsung support?

They already do. 4.3 does a great job.

I am not sure. I flashed the latest Resurrection Remix ROM and the battery life was a lot worse than TW.

My batterylife is better with AOSP than with TW. For 4.3 I recommend slimbean and included kernel, thor kernel gives crazy good batterylife too on 4.2.2/4.3 roms but thor is banned here.

For me Samsung roms are far more effective.
On CM based roms, i get max 2/3 days with my usage, while on Samsung roms i can get 6 days (once got 7 days of juice )

Thor Kernel gives better battery life than stock SlimBean?

My experience with PA 3.65 based on AOSP was mediocre in terms of battery life. I certainly love it much, much more than TW but I certainly couldn't justify keeping that ROM since it was pretty average with respect to battery. It wasn't like ridiculously bad but certainly 25-30% lesser than what stock TW usually gives me and hence I had to sadly move back to a TW based custom ROM. I am hopeful that eventually AOSP will get closer to TW in terms of battery life because in every other sense I find it better.

I was too upset to see the terrible battery life on Aosp. Only thing that keeps me away from them.
Don't know why they can't match up tw in terms of battery life.

I'm on cyano official 10.2 and battery life is quite decent but far from the Samsung roms. But I love cyano, and I think that the more drain is worthy.

On CM 10.2 or PA 3.99 I use SetCPU to create 3 profiles;
1) Screen off, max CPU=400, Governor=conservative
2) On call state, Max CPU= 500, governor= the same as the ROM
3) battery< %10, Max CPU=1000, Governor= the same as the ROM
One more thing; I don't think Samsung gives the same effort on giving a smooth experience and I don't think it is about bad software. I think the software is well-coded to perform efficiently but the CPU jump is tuned to be lower and slower intentionally. So it gives some choppiness compared to CM or any AOSP ROM but it also saves some energy from the CPU (or GPU at certain times)..
Basicly speed comes with cunsumption

Thanks. I applied all your settings and i set zzmoove as default governor (seems that is more battery friendly than pegasusq).
The story that you said about sammy roms is embarassing. I had an iPhone 4 before my Note 2 and it was completely smooth with a downclocked single core 1 ghz cpu. And battery life was pretty decent. I can't believe that android need so much power.
So, we can assume that all the other smartphone with great battery life (razr maxx, droid maxx, lg g2....) have choppy ui? I think (and i hope) that is related just to the optimization. Maybe samsung is not able to optimize the Touchwiz and prefers the Jeremy-Clarckson approach of "YEAAH, MORE POWER".

No. We can't assume such thing. Mine was just an assumption only for Note2/S3 Touchwiz vs AOSP.
Besides iPhone 4 is not downclocked, it has just a very high treshold for the last step (1GHz) so it comes into play very little. I remember such thing for dual core Sammy devices (or was it One X, poor memory of mine) from a kernel developer. He/she had tuned the kernel with very high tresholds for 800MHz and 1200MHz so the device was going easily 800 MHz but waiting there until there is huge load of porccesses and then jumping to higher clocks. So that waiting time on a stable was saving some battery and heat since the higher coltages are less efficient for both the battery and heating..
One more thing; the smoothness of an iPhone is not related to its CPU, it is all about the GPU which used to be higher than any same generation Android device until recently..

Anyway, I've tried the parameters that you said, but on cm 10.2 the phone freezes in a black screen when is locked. Seems that I solved with a simple step up from 400 to 500 mhz when display is off. Just a report for the users that are reading this

Why there is no Thor kernel in XDA? Or have my eyes missed it?

please visit Thors own site - Tegra owners.
if you are a lover of android then your experience cannot be complete without experiencing his 'touch' and you need to read through the threads there - his kernels just dont work without following his instructions.

Thread closed as it has already turned into a best rom/kernel thread. It appears that the question has been answered anyways.

[Q] Hey guys, newbie here, got a question

I am sorry if what im about to ask is already posted somewhere (probably is), but this forum is pretty vast and I couldnt find what im looking for. The question is this, Im using Vanir ROM. Now with the inbuilt kernel I had around 20k benchmark on antutu. I flash hells core, excited to see any difference and whoop, i got 14k. Also i checked the part with 3D testing and fps was higher for about 5-7 points. So what Im asking is this,What is the meaning of this and also how can I, how to put it to not sound noobish, tweak the kernel to perform/save battery etc.?Because Im assuming thats not the top what HellsCore kernel can do, am I right? Or if you guys have any kernels to recommend, all is appreciated. Also if this helps, Im using Nexus 4, Vanir ROM(as posted above) and dont know what else would you need to know to answer.
Thanks in advance
/So I rebooted and now I am on 20840 for some reason.

Benchmarks are not very conclusive abnout anything. Each phone is different each user has different needs and how and where there phone is used. Everyone will tell u to try this kernel and that kernel but u just have to find one that works for you

I get that, i was more concerned about those numbers. Why did it drop to 14k and then went to 20k again.

Probably some patches were included in the rom's kernel, which can affect the scores.
When you flashed another kernel (helldoctor), you stopped using these patches, so scores went down.

Anututu and other benchmarks depend on a number of factors/conditions which affect the final result . The major conditions which affect it result are below
1) The CPU temperature !! When ur phone gets hot the CPU throttle will automatically reduce the active cores and the clock speed to cool down your CPU !! This results in decrease in performance !! When you flash new kernels its possible that ur phone is hot and hence performance decreases
2) Using your phone while running tests also affect the results . for eg if there is a notification during the test or background sync going on it will affect the result
3) probably the kernel packed with vanir had 4 cores active all the time to increase scores and hells core has just 2 cores active ( at a given moment) will mean decreased performance
The ideal way to test kernels is as follows
1) Dirty flash your ROM before flashing kernel
2) Reboot your device after the first boot
3) Let it settle down for an hour
4) turn of data/WiFi during the test
5) see the kernels specs( like cores active/the maximum CPU speed) through an app like trickster/faux clock
6) Now run the test
7) after test let your phone cool down for 15 mins
8) repeat the test a few times and take the average of all scores
Kindly hit the thanks button as a token of appreciation

Antutu was never accurate if you ask me. Sometimes it goes down and the other it went up..so..

I see, thank you guys.

Benchmarks are like putting makeup on.
