Delete 01cpufreq_governor and 02cpufreq_screenstate_scaling?

Also, SetCPU keeps forgetting that I allow it root. Yes, I checked off the "remember" box.
[Acer Iconia A500] daveid:
I wanted to quote this in case anyone else is having this issue. Since doing the above, I have zero issues.

Well, did it again, but disabling wifi and running fixwifi from an su terminal fixes without reboots or deleting any files.
[Acer Iconia A500] mburke178:
Delete the etc/init.d script and setcpu works fine. Something in Vaches scaling screws up setcpu. Lightspeed ROM uses vaches script which is why you keeps having problems. It isn't a kernel issue.
[Acer Iconia A500] agentfazexx:
Gotcha. So both files I mentioned should be deleted? init.d is where all scripts are stored by default.
[Acer Iconia A500] mburke178:
Just completely delete the unit.d file. Cache explained it in the taboonay thread. Or as you seem to say to everybody use the search function.
[Acer Iconia A500] agentfazexx:
Well I renamed it. SetCPU still doesn't remember that I am selecting "Remember" for allow root permissions. Any way to stop that from coming up every time I open it?
[Acer Iconia A500] mburke178:
Update the binaries for your superuser
[Acer Iconia A500] agentfazexx:
Remove with Titanium and install from Market?
[Acer Iconia A500] mburke178:
Open SU, go to settings, scroll to the bottom, your SU binary should be version 3 beta 2. If it isn't then update it. I don't know what version lightspeed rom uses as I prefer taboo, but if isn't superuser version 3.0 beta 1 (29) then uninstall and Google the apk.
[Acer Iconia A500] KennyNair:
Realised that the browser is slowing down on sites heavy on Java script with this kernel. Anyone know how to solve?
[Acer Iconia A500] paisanmi:
Youtube on web page is also running not smooth.
[Acer Iconia A500] HIcycles:
I noticed that I get freezes in air attack HD between level changes. Restored 2.2 and everything is fine.

Just a side note, for whatever reason, linpack is reporting about 22 Mflops with 2.5 kernel, while 2.2 is reporting about 91 @ 1.5Ghz
[Acer Iconia A500] richardtrip:
Still getting 90+ on the 2.5 kernel. What's your current rom?
[Acer Iconia A500] thor2002ro:
some times linpack does that... force close it and clear data... and do the test again...
[Acer Iconia A500] richardtrip:
Never used linpack before this test :-)
[Acer Iconia A500] HIcycles:
Using HoneyVillain 1.5a. I'll give Thor's recommendation a shot. Didn't think about forceclosing it.

Thanks for your hardwork. I love the ROM and Kernel.
[Acer Iconia A500] tweeker404:
What would be a safe bet for a game pad to purchase that would work properly with this? Any other options besides an official PS3 controller that was reported working?

Haven't heard anyone else comment on what they have used specifically but was looking to find something that would work properly.

Wanted to also note this kernel has worked tremendously for me and is very fast with HV ROM.

Thanks so much for your hard work richard.

Review of 2.5 kernel

Hi again,

just tried the newer kernel together with 1.05a ROM and for me this kernel is not better:

- Because now interactive govenor is deactivated I am forced to use onDemand.

- I experience in MoboPlayer a strange performance drop after about 1min videoplayback. This lasts about 10 seconds and done the video speeds up again.

- I had the same problem with 2.3 kernel, but the interactive govenor fixed that issue.

I didn't experience a problem with interactive govenor as described here, I had more or less a problem with onDemand govenor, but only in videoplayback in moboplayer.

Please could you explain the problems behind the interactive govenor, according the google description I would prefer interactive compared to ondemand govenor, because this should give you a better UI experience.

Maybe the CPUload detection is corrupted, because we have no two CPUs and the measurement is done on the wrong CPU? May it be linked to programs which runs only on one core instead of two? Maybe a lot more finetuning is necessary to get this working as expected. Does anybody now how the state if for the other two core android devices?

Best regards
[Acer Iconia A500] dragonsportbikes:
Team help, using the 2.5 kernel with on demand but my governor keeps changing to conservative on its own. Its driving me nuts. Anyone else experiencing this?

I'm puzzled!!!
[Acer Iconia A500] FSGuruh:
Experienced a lot worse performance compared to 2.3 kernel.

Can you verify if the older kernel is faster for you es well?

How do you know the govenor goes to conservative? Maybe I have the same issue.
[Acer Iconia A500] mburke178:
my guess is you are running either taboonay or lightspeed roms. if that is the case use root explorer and delete the etc/init.d file and all will be well.
[Acer Iconia A500] agentfazexx:
As stated in a few threads, use Root Explorer and delete the whole /etc/init.d folder. If you don't want to delete it, just rename it to something.
[Acer Iconia A500] dragonsportbikes:
Worked like a charm. Thanks for the help!!!
[Acer Iconia A500] dragonsportbikes:
You da man. Worked perfectly!!!!
[Acer Iconia A500] monkey10120:
I recently flashed back to 2.3 from 2.5 because it I faster but in both kernals I'm getting a quadrant score if ~2000? It seems kind of low especially when over clocked to 1500. Anyone else have this?
[Acer Iconia A500] goofytim:
I am running the 2.3 kernel and I have setcpu using a max of 1400MHz. When I run quadrant I get 2258. I am on stock ROM, 4.010.13.

Make sure you run it a couple of times because the first score never seems accurate. I usually run it 3 or 4 times until the score basically stays in a very tight range.
[Acer Iconia A500] monkey10120:
I am also is the same stock version. I ran it about 6 times already and it is not getting above 2100. Its just that I've seen scores all the way to 3200 on the iconia!
[Acer Iconia A500] goofytim:
Were these scores coming from a custom ROM?
[Acer Iconia A500] monkey10120:
Yeah I think so. They would have to be. But what would make them that much faster. Especially if there from the same 4.010.xx build.
[Acer Iconia A500] monkey10120:
How come updates on the Iconia roms and kernals slowed or stopped all of a sudden?
[Acer Iconia A500] ribbe82:
Well, less updates gives time to test more thoroughly.

I've tested kernel v2.5 for 10days, and I must say it's not perfect.

The main problems were:

- Tablet got terrible slow or hangs after a day or so, particularly when using 3D-photogallery.

- Battery stats are completely unreliable: many times it gave me 'charging' when there was no powercord connected, and when 'on battery' it didn't update the powerstat after a while, so for example I had 60% battery left forever ;) After reboot battery stats were updated.

I think the 'time on battery' simply froze.

It turned out to a reboot every day, and several 'wipe battery stats', but that didn't help.

I'm back to kernel v2.2, and after 10mins I already must say it feels smoother. But to be fair, I must also test this for at least 10 days and then pull the conclusion.

So for now I stick to my previous statement:

@RichardTrip, please see this as constructive criticism :D

Love your work and hope you can continue with this great things.
[Acer Iconia A500] vikramdhani:
where is the download link ?
[Acer Iconia A500] B214B1:
That would be in Post #1.
[Acer Iconia A500] richardtrip:
No problem. I can handle constructive criticism (but on vacation right now and didn't take my notebook with me). Just hang in there for a couple of days before i try to make things better :-)
[Acer Iconia A500] richardtrip:
Vacation...... :-)
[Acer Iconia A500] ribbe82:
Oh well, time for me to buy you a beer then. Enjoy your vacation, mine begins next week:cool:

So far after one day I have none of the issues I mentioned yesterday. Everything is fast and battery-life is longgg (not because it stops counting!;) it works as should be)

Yesterday I connected a camera via USB-cable, and was able to see the pics from the camera on the A500, how cool is that! (Ok maybe you guys knew all the time, I didn't). So it's supported already in 2.2 kernel, great!

Another simple test: in v2.5 the rotation lock isn't working, in v2.2 it does.

Ok looking forward to your updates, cheers!
[Acer Iconia A500] agentfazexx:
Rotation lock works in 2.5 for me.
[Acer Iconia A500] thor2002ro:
Rotation lock is rom specific...
[Acer Iconia A500] agentfazexx:
Exactly...

Does the minimalist 3.2.1 ROM work with this kernel?
[Acer Iconia A500] thor2002ro:
nop.... it uses 3.2 xoom libs so needs xoom like kernel 3.2
[Acer Iconia A500] agentfazexx:
So this'll only work with 3.1 ROM's...argh.
[Acer Iconia A500] thor2002ro:
it will work with roms that use the acer 3.1 libs...
[Acer Iconia A500] agentfazexx:
Yeah, I'm on LightSpeed right now.
[Acer Iconia A500] ribbe82:
Ok then I'll take back those words.
[Acer Iconia A500] themono:
The minimalist rom uses a slightly modified version of this kernel by default.
[Acer Iconia A500] agentfazexx:
Really? So just wipe everything, flash the ROM and leave it be? Can I OC with this ROM with SetCPU?
[Acer Iconia A500] muqali:
When you say ROM you mean this kernel? I only cleared my cache and Dalvik cache. User data shouldn't need to be removed afaik. Yes, if you're rooted(which you'd have to be to install the kernel) you can overclock with SetCPU. You can also under/over volt. I have a lower volt profile set up for when I'm just reading Kindle or PDFs.
[Acer Iconia A500] agentfazexx:
We're talking about minimalist 3.2.1, as posted a couple posts ago.

So, still new to this device. I just wipe everything, flash the ROM and the kernel is installed with the ROM?
[Acer Iconia A500] themono:
Correct. And yes, overclocking is enabled by default.
[Acer Iconia A500] entropy.of.avarice:
thank you so much

Running stock 3.1 - rooted, cwm running. Backed up the stock system via nandroid, used set CPU to run 1.4 ghz - the difference I see in system response in pretty much everything I do is unreal. Thank you, donating for the work now - amazing what a difference 1.4 GHz makes.

So happy. Thank you again.
[Acer Iconia A500] muqali:
Yea, as soon as the first hits I'm gonna toss you some cookies. I'm satisfied enough with the stock UI that I don't feel the need to alter anything but the kernel and that's just for the filesystem modules and the overclocking.
[Acer Iconia A500] richardtrip:
Update

Version 3.0:

Fixed graphical problems for 3.2 (only for HC 3.2 as of now).
[Acer Iconia A500] agentfazexx:
Disable the conservative governor for SetCPU again!!! You did it in 2.5!
[Acer Iconia A500] richardtrip:
i disabled interactive (not conservative) in 2.5 (the same as in 3.0).
[Acer Iconia A500] beastmods:
is there any way to fix the block loading in the web browser? Takes pages a sec to catch up.
[Acer Iconia A500] agentfazexx:
I remember long discussions about the governor switching around from ondemand a while ago. Something was done in 2.5 that changed in 3.0. SetCPU is controlled via kernel.
[Acer Iconia A500] richardtrip:
Isn't there a governor scaling script in lightspeed?
[Acer Iconia A500] agentfazexx:
Not that I've seen.
[Acer Iconia A500] richardtrip:
I can't check to make sure :(
[Acer Iconia A500] agentfazexx:
Search this thread for the word governor, you'll see the conversations.
[Acer Iconia A500] B214B1:
As has been said before... I've been watching Setcpu on mine religiously since you asked the first question regarding switching from Ondemand. Mine stays put at ondemand. You seem to be the only one that has mentioned this. I'm not saying its not happening to you, but nobody else has mentioned it.

Have you tried changing the OC settings to something basic to see if its an issue with Setcpu?
[Acer Iconia A500] agentfazexx:
Read what I just posted, you probably missed it.

I'm using normal settings, just like on my HD2 before I started using CM7 CPU voltages. I go in, max everything out and set it to ondemand. Switches to conservative on its own.
[Acer Iconia A500] richardtrip:
i bet it's your rom.... (ask smaury where the script is).
[Acer Iconia A500] B214B1:
Nope....Didn't miss it. You've checked and made sure there isn't a profile you've set that might be kicking in? Or as often as you seem to switch Roms, maybe your backup has some legacy info thats causing issues. I seem to remember you asking about preferred backup programs not too long ago.

I've maxed my settings out on setcpu, with -50 undervolt, so far no switching.

As far as all these conversations about governor switching.... I found one(besides this one). And that was with kernel 2.5, which you said didn't have the issue....
[Acer Iconia A500] mjd1975:
I have this new custom kernel installed on my A501 but see no longer 3g? Does anyone have a solution?

[Acer Iconia A500] FloatingFatMan:

There are currently no custom kernels fully compatible with the A501.
[Acer Iconia A500] mjd1975:

where is the control?

in have install from cwm for honeycomb 3.2. where is it, cant find the program to over clock? can u guide me pls
[Acer Iconia A500] B214B1:
There is no overclock program included in the Rom or the Kernel(which this is). You have to download it from the Market. Most use Setcpu. Its not free. There are others.
[Acer Iconia A500] davenull:

so i flashed [ROM][HC3.2] Taboonay 2.0 (24/08/2011) and this kernel.

but now it seems that my acer iconia a500 does not boot anymore.

i get the acer logo, and then it disappears and the screen goes black.

the device vibrates once every couple of seconds, and it remains this way.

what can i do ?

is the kernel i flashed the problem ?
[Acer Iconia A500] B214B1:
Its not the Kernel. Its the Rom. Go to the Taboonay Thread for the fix.
[Acer Iconia A500] Athrun88:
Had the same problem. Suggestion is to wipe and install Taboonay 1.1 then 2.0 right ontop of it without wiping everything. Worked for me and it's running flawlessly. Now to install this kernel and see if everything stays okay.
[Acer Iconia A500] autom8r:
I can run with 1.2 ghz all day without problem. When i try 1.5 ghz the tablet freezes and reboots continually. I looked at the voltages for 1.5ghz and noticed it was 1250mv vs. The 1325mv. shown in the OP. When i go into setcpu it allows me to lower voltages, in this case, I want to increase the voltage, how should I go about doing this? Furthermore, I ran the bechmarks and got results of less than the Samsung Galaxy S2, does anyone know what overclock these benchmarks were run at?

Thanks for the help
[Acer Iconia A500] mjd1975:
Richard,

Is it possible to make a custom kernel with 3G support?

I'll be happy When I turn 3G on that i have a bit of overclocking:D:D
[Acer Iconia A500] zimphishmonger:

[Acer Iconia A500] calgop:
I can't find interactive scaling in SetCPU.

How can I ?

Sory about my English.:p
[Acer Iconia A500] themono:
I believe it is a temporary thing - there was a glitch where it wouldn't scale back up after scaling down, as I recall.
[Acer Iconia A500] agentfazexx:
It automatically scales back from ondemand actually, which causes CPU speed settings to fall. Pretty annoying.
[Acer Iconia A500] cloud79:
Is the portrait lag (wich is still present in HV (3.2)) a kernel related problem?
[Acer Iconia A500] D_Steve595:
Google says it's a hardware problem. But I doubt that.
[Acer Iconia A500] richardtrip:
In next version: added new touchscreen driver (no more touchscreen wake bugs), reverted the wifi driver (maybe fixes some problems but i can't check because i didn't have any wifi problems).
[Acer Iconia A500] richardtrip:

Version 3.1:

Fixed touchscreen sometimes unresponsive from wake (new driver)

Reverted to older wifi driver (hope to fix probs for some people).

[Acer Iconia A500] schaze:
does the 3.1 kernel also work for 3.1 ROMs (e.g. HV 1.05a), or again HC 3.2 only?

Hello

I've flashed these kernel v3.1 with HoneyVillain 1.1 on my PB Liberty Tab.

It runns fine, but after a while there are a massive lagging.

Changing CPU speed and govenor doesn't help, only a reboot helps to normalise these situation for a short while.

The same with stock kernel.

The kernel from tegraowners.com doesn't have these problem so far and HV 1.1 runns like hell. :)

There must be something, that causes an incompatibility on PB tablets.

Can you have a look on it for future kernels ?
[Acer Iconia A500] paisanmi:
Thanks Richard, it's fixed but the interactive governor is gone again :(.
[Acer Iconia A500] bwassef:
Yea, i am having the same issue. is this because of the ROM update or the kernel?
[Acer Iconia A500] tjkriegel:
I'm also still having the wifi disconnect issue. Also getting it with stock kernel and Thor's as well. Revert back to 3.1 and no problems.

Same here finally had to restore my 3.1, just kept dropping to much.
[Acer Iconia A500] arffer:
Mirror image screens

I flashed from 2.5 to 3.2 today. After rebooting (tried a few times), I noticed that my lockscreen was a mirror image, like I was inside my tablet looking out (Acer Iconia running stock Acer_A500_4.010.42_COM_GEN1).

I still had to use the touch screen in the normal touch points. For example, the 'padlock' image to be swiped to unlock appears backwards and on the left side of the screen, but I had to pretend it was in the normal right hand side of the screen to swipe it.

My home screens were normal, not mirror, but all the settings, notification, and keyboards were all mirror images.

So I flashed to 3.1, and same problem.

Flashed back to 2.5 where I started from today, and everything is back to normal!

Ideas or suggestions?
[Acer Iconia A500] tjkriegel:
Version 3.0 and higher of this kernel is for 3.2 based roms, since you're on a stock 3.1 that's probably what's causing the issue.
[Acer Iconia A500] bwassef:
I added this to the build.prop file and cell data isn't disabled.... its been a few days. Am I doing something wrong lol? Would a data wipe do anything?
[Acer Iconia A500] arffer:

[Acer Iconia A500] Johnny0906:
Is anyone experiencing random crashes (not FC the message doesnt appear) but just crashes/disappears.

It happens when I am surfing on the web or another place I noticed was google maps.

I am on 1.1 right now and waiting for my Acer to recharge. I set my CPU to max 1408.

Also is it just me or was 'Cell Standy' not gone before and looks like its back now in settings -> battery use?

I mention this because I remember a DRAMATIC improvement in battery life when 4.010xx came out.

Cheers!
[Acer Iconia A500] :

[Acer Iconia A500] shin lucifer:
Grrr just checked dam Cell Standby @ 18%. I am still on version 1.1 for now.

No issue here, just checked on version 1.1.
[Acer Iconia A500] caz70:
updates .38 and .40

I've compared both updates and they are almost identical. .38 contains a new xt9 stack on top. 40 is missing that, probably it was integrated in .24 already.

The other new things are a new flash apk, a new kobo reader and something called CheckerLaunch.

But more important, both contain the famous fixwifi setuid root program together with a background service. Is that fix still needed with the new kernel ? Did anyone attempt to trace what fixwiki does ?

Carsten
[Acer Iconia A500] caz70:
To answer my own question, fixwifi seems to remove the dhcpd files and will probably restart dhcpd as well, so the problem is probably not kernel related but lives in userland. :-/
