Hi,
since I flashed my Nook to the latest nightly and now to 7.1 RC1 I don't have any additional governors any more. I flashed the Kernel correctly after the rom and I can choose the higher clock speeds. However, I still only have the three standard governors. (conservative, ondemand, performance) With 7.0.3 I had at least interactive as an additional option. How do I get the other governors? Which one is the best option for standard use?
I use the emmc version of the latest Dalingrin kernel and CM7 is installed on emmc.

As Dalingrin has noted in the Kernel thread, interactive has been removed; the three govs you have are the only ones you are supposed to have. I can tell that without a full read it might be easy to miss, so yeah... that is what is happening.
Hi everyone,
I just have a little question.
It seems that when installing Fugumod kernel, users (including me) start to experience some lags on some (unknown to me) circumstances. These lags are easily solved by setting the min frequency to 166 MHz (I do that with pimp my cpu). My question is : Is that behaviour different than with the stock kernel ? I mean what is the min frequency on the stock kernel ? 83 MHz like the fugumod kernel ? Setting 166MHz as min frequency is a patch or is it just putting back the same value as the stock kernel ?
I known that I could easily test it by myself just by putting back a stock kernel over my fugumod kernel, but I already converted all three FS to ext2/ext4.
And btw, i like my Fugumod kernel so thanks to Sebastien and the others for their work.

yes the default freq for the CPU are 667-83 and if want to use THE DEFAULT freq than flash a non OC version of FUGUMOD

Thanks, but that was not my question ;-)
I simply want to known what is the behavior of a stock kernel regarding cpu freq. Is the min frequency on a stock kernel also 83 MHz or something else ?
Fred.
I think the main problem is the governor, or wrongly chosen governor that keeps the cpu stuck too low

My mistake, as you talked about fugumod OC, I though you were referring default freq range for FuguMod instead of the stock one.

Thanks, but it lead to other questions ;-)
What is the default governor of a stock kernel ?
As I am using FuguMod 2.4 800, and PimpMyCpu tells me that there's no governor, is it safe to assume that it's the same governor on my FuguMod version and on the stock kernel. If so, why lags on Fugumod?
And finally, on Fugumod kernel what would be the best governor. My aim is more battery conservation than pure performance, yet these lags @83MHz are extremely annoying.
Thanks,
Fred.
well on my i phone i also prefer to use the conservative governor but when it comes to play heavy games i change the governor to performance.
for saving battery make a screen off profile with max frequency 166 or just a bit more that that...
it saved a lot of my battery...

This is an Unofficial Semaphore Kernel
Stratosk does not support it
So do not bug him if you have a problem with this kernel. But bug me instead!
If you guys want to see some more features added to this, feel free to tell me and I'll try my best to add them to it.
Please note that there are 3 variations:
Normal versions: for CM10 or ROMs without hugemem configuration, available RAM 384MB - 396MB
"s" versions: for Slim Bean ROM or patched ROMs with hugemem configuration, available RAM 397MB - 409MB

How to:
How to enable Swap?
To enable Swap, you'll need to create a swap partition on you External SD card. I recommend following this guide for it. http://forum.xda-developers.com/wiki/SD_card_partitioning
1. Make sure to backup everything from your SD Card first
2. Do not reformat your SD Card while it's still in your phone, take it out and plug it to your computer through a card reader!
3. I recommend that you only create a Swap Partition around 256MB
4. Follow that guide and when you reach to Step 3, select the option "Linux Swap"
5. When you finished following that guide, plug in your SD Card to your phone and Reboot to Recovery
6. Then flash this zip Enable Swap
7. Reboot your phone and you should be good.
8. To make sure Swap is enable, go to Terminal Emulator and type "free".
9. You should see some info at the bottom about Swap.
How to Enable Zram?
To enable Zram, go to (Settings -> Performance -> Memory management.)
Or Flash this zip Enable Zram
How to use the OC'd Steps?
To use the OC'd Steps, use Nstools or CM Performance Settings (Settings -> Performance -> Processor -> Maximum CPU frequency.)
If the chosen Frequency setting is not sticking with Nstools or CM Performance Settings, try using CPU Control Lite or Voltage Control.
I flashed the "s" version and now 720p recording or playback is not working?
You'll need to flash HugeMem Libs first and then you should have your 720p recording or playback working again.
How to get rid of the Green Screen Flash and get the best colour if using VC version?
To get rid of it, I recommend using the following Voodoo Color Settings. To change them, use Voodoo Sound app (Available from the market).
Color profiles
Voodoo profile v1
Screen RGB multipliers
Red: 286xxxxxxx
Green: 333xxxxxxx
Blue: 392xxxxxxx
Screen v1 gamma hack
*Reset to 2.3.3 Then Change*
Red: -26
Green: -30
Blue: -33
Or use this gamma hack (Might get the green screen flash but with a better looking colour, thanks to aduka)
Red: -40
Green: -40
Blue: -31
*If you're still getting the green screen flash, increase the "Screen v1 gamma hack" by +4 for the red, green and blue till you stop getting the green screen flash*

By default I've increased the voltage for the 1200MHz step to 1350 mV to make sure it's stable for everyone else as not every phone is same. But once your phone is stable at 1200MHz, you can undervolt the voltage until you find a sweet spot.
Like on my phone, I was able to undervolt the 1200MHz to 1275 mV.

I UV by 50 with this kernel and devil kernel the same. Stable enough for me
Also. Nick0703. Sorry for posting in Stratosk thread regarding your kernel.
I was wondering how to make the 1200mhz stick. I tried through settings and then tried with nstools. No go on reboot.

Hey Nick0703 would you be able to get screen off min 100mhz max 400mhz settings into the kernel or is it not really needed? I guess it sits at 100Mhz idle. Also, are you able to deep idle? BTW 1200 is optional but it wont stick on reboot still. Your settings disabled nstools to default.
Re: [KERNEL] Unofficial Semaphore JB 2.9.8.c
Try cpu control lite or voltage control if the settings do not stick.

I could add the screen off min 100mhz - max 400mhz to the kernel but I don't think you'll see any difference from it. But I compile a test version with that option and see if there is any difference. And yes, I'm able to deep idle. Deep idle works fine with my phone but keep in mind that not all the captivates are the same.
And for the 1200MHz, try using CPU Control Lite or Voltage Control just like sephhi stated.
Thanks guys. Good looking app but it didn't work. Not sure why. Always able to set to 1200 on devil kernel 4.1.2

Version 2.9.9sc has been compiled. But it will need to go through testing first as the kernel configuration file had some few changes.
I'll need 2 people to test it. If anyone is interested, send me a PM.

Hi, new user here so I can't actually post this into the franco kernel thread, but is anyone else not able to change the governer on franco r97 (nexus 4) to anything other than conservative? I'm on bigxie's unofficial PUB build 5 and using trickster mod.

Give Franco Kernel a shot; Carbon should also have that option or just about any. I believe Trickster Mod has its own App to, which would work well for that specific kernel.
