[EzyICS by Mengpo v1.1][Kernel][P6810] For Stock XXLPL and optimizations

Disclaimer :
I am not responsible if you brick, break, blow up, drop, lose, or get your device pregnant. Everything you do is your responsibility.
This kernel is only made for the GT-P6810 WiFi only Tablet, It is not compatible with Locerra CM9 nor CM10, and it may not work on everyone's device. I'm not a real developer and I don't know how to fix your device if you break it!
This kernel is forked (a direct copy to be more specific) from the EzyICS Kernel v1 and I thank again Ezynow for his hard work. I took his changes from his topic and adapt this kernel to the P6810. Actually, I took the .config and compare line by line which was for the P6800 and which was for the P6810. So, I disabled all the gsm/modem devices.
This kernel is not perfect and needs be to improved so don't be harsh if there's some kind of problem. I've tested it again tonight and I did not brick or whatsoever other problem... I'll list on the features which one are working and tested and others which don't.
There's only one file to download and flash it with the locerra's cwm. So, you have to install locerra's cmw first ! See below
Bugs​
None known yet
Features​
Removed MMC_CAP_ERASE (BrickBug) (tested ok) like Dedrak's one I did this :
Code:
//mmc->caps |= MMC_CAP_SDIO_IRQ | MMC_CAP_ERASE;
mmc->caps |= MMC_CAP_SDIO_IRQ; // Brick Bug Fix
Built from GT-P6810_ICS_Opensource_Update1.zip;
Support for bootanimation. Place the bootanimation.zip in /system/media folder.
Various compiler optimizations (neon, cflags :-O2 -fomit-frame-pointer etc.) (Debug stuff remains for now but will be taken after some more mods are added);
Mali state tracking disabled;
/etc/init.d/S* script support (Add here your tweaks / ramscripts from custom roms etc.) (tested ok)
Added Governor :
Pegasusq (by default) - (recommend as it deals better with multi-cpu devices like our tabs but may require some tweaking)(tested ok)
interactive;
lulzactive;
lulzactiveq;
smartassV2;
hotplug.
I don't know if these governors will suit to our tab and they need to be tested.
Overclocking Support up to : 1600 mhz. It test further but the tab was not stable enough and as Ezynow said : ICS changes how frequency control is implemented so not as easily overclockable as honeycomb was. Fixed CPU Boot Up frequencies to default values / not overclocked settings (tested ok)
Undervolting Support:
Same frequencies as Eznow used : 200 / 500 / 16000 hz (As these are the most used)
So far running pretty stable on:
Code:
1600 mhz -------------------> 1300mv
1400 mhz -------------------> 1250mv
1200 mhz -------------------> 1175mv
1000 mhz -------------------> 1075mv
800 mhz ---------------------> 1000mv
500 mhz ---------------------> 875mv
200 mhz ---------------------> 875mv
ALL DEVICES will have different values but these values gave by Ezynow worked for me. Use SetCpu to change voltages or cpu overclocks. (tested ok)
Slightly undervolted GPU voltages and thus reduced by 50mv for default GPU levels. (tested ok)
in built CIFS support. Changed Max_BUFFER Size to max 130084 (Thanks to Pinkowl for first supporting this).
In cifs options put: rsize=130048. (tested ok)
NFS share mounting. (not tested)
UDF & ISO support - i.e native bluray disk support. (not tested)
Here is information on it This is configurable using a tool known as NSTools on the PlayStore. When using this 100% means the bus frequency is at 100% try not to get confused. So 100% of 100MHz would be 100MHz so if you increase it to 120% so it would be 120% of 100MHz would be 120MHz and this value applies to all CPU frequencies, GPU ect.
Compatibility list​It seems to work on all stock ICS releases or derived custom ROMs.
CM9 - Not working;
CM10 - Not working;
XXLPL - Tested: (tested ok)
Install​Go into CWM.
Make a nandroid backup.
Install zip from sdcard.
Problems​Go into CWM-> Advanced restore -> restore boot.
Changelog:​v1.1
Default cpu scaling governor set to pegasusq (siyahkernel version).
Enabled bootanimation;
pegasusq cpu scalling governor added (siyahkernel version : more stable);
interactive cpu scalling governor added;
lulzactive cpu scalling governor added;
lulzactiveq cpu scalling governor added;
smartassV2 cpu scalling governor added;
hotplug cpu scalling governor added.

If you want to add features or just want to ask questions feel free to do it

Oh nooo I on P6800..
If I on P6810...will whack this on my Tab
Nice...keep it up mengpo, any chance for P6800?

I have a suggestion for the Pegasusq governor. You could perhaps tweak it according to siyah kernel like on the sgs2?

I really can't remember if there was any link describing the pegasusq governor when it was first introduced but however, the link below is for the sources. not really sure if it will be of any use to you though. perhaps some features could be implemented over?

there are also some information about the ICS kernel for sgs2

Hi Mate,
Great to see the development you've made! Excellent work :good:
Still away right now and hopefully missus will have sorted out a place to stay (and ADSL) by the time I return.
Need to (want) to get started on a new ROM build for P6810 (P6810XXLPM), but that won't happen for 2 weeks.
Would love to take your kernel for a run then
Keep it up

Simple. Don't use it. This is just the first version created by Mengpo and is bound to have issues here and there. I'll wait for him to post an update (whenever that happens) before evaluating and trying it.

I did an update and changed the scalling governor (pegasusq with pagasusq (siyah version). I think the problem went from there and thus you won't have this random reboot issue.
good luck !

The v1.1 download link seems bad; says file is deleted.
Also anyone use this on Skyfire Rom, which seems based on the same stock firmware?

[Q] NoFrills and SetCPU not working correctly on roms

Hi there, noticed an issue with NoFrills and SetCpu not working correctly on any Rom I have installed, I am using latest Prometheus kernel for sense,(767).The issue is that I set max to 650 or 678 and the minimum to 320, The max value is fine, but the minimum value
always changes to 480 after a reboot.Also the governors revert back to default setting.
This is the same for various cm10 based roms I have tried, with latest Nope kernel. Any ideas what is wrong here. Thanks .

After the reboot, this always happen...so just select the option "SET ON BOOT" in setCPU, or system settings or any other app...
What this does is that it restores the device cpu back to the mode which you had set!!!
Enjoy and press thanks!

Thanks for the reply, I forgot to mention in my first post that I already had those 'set at boot ' options enabled. Could it be permissions? They look right, according to other apps permissions that is.

[Stock][Patch] Overclock

Hello
This is not my scripts, I found them on the internet after many hours searching - I checked and they work
These scripts can slow down or speed up the processor
http://omniimpact.com/android/roms/myfishbear/Droid 4 Roms/JB Roms//Jb Patches/OC Scripts/
1.1GHz (ULV, LV), 1.2GHz (N, LV, ULV), 1320MHz (N, LV, ULV), 1370MHz (N), 1375 (N, HV), 1380 (N, LV, ULV), 1400 (N, LV), 1425 (HV, LV, ULV)
I tested the 1.1GHz, 1.2GHz, 1.4GHz, 1.42GHz
I using 1380MHz, 1420 is unstable
Tested on Android Stock 4.1.2 98.72.189.en.US
DOING THIS AT YOUR OWN RISK
Installation - install package for Stock ROM
I recommend having Safestrap for possible repair your phone in case of emergency
Credits:
myfishbear for created OC scripts
Fervi

@ferviverus how do you apply these scripts? And how are they working for you? :silly:

I install it directly to Stock Rom (like Mentors Rom)
Sometimes the stock Rom doesn't start, then you install other overclock script
I recommend to use 1380MHz version or lower
If the phone boot propertly with this patch, install "No-frills CPU Control" (from f-droid for example) and check Max clockrate is 1.38GHz
If you have 1.38GHz, go to CPU Control Settings and set 3rd option (other applications (or system) cannot change cpu frequency).
http://gmclan.org/uploader/6184/Screenshot_2015_05_05_09_40_20.png
If you install patch and clockrate is still 1.2GHz (and you can't change it manually), probably you need also init.d support
Fervi

Can someone please tell me what D4HD is? Is it a ROM?
(It's the same folder with overclock patches)
Anyway, I just patched Beats.zip and D4HDWidget.zip taken from the same domain. They work like a charm
One thing I notice is that after patching D4HDwidget, my homescreen now stays in background i.e more free ram :victory:

Thanks man!
Does it have double tap to wake support ?
And how do I install it? Flash the zip via TWRP?
And if I do so will I lose any data and more importantly the twrp recovery itself thats built in the kernel?
( im on stock 5.0.2 unlocked bootloader with custom kernel by xenius9)

No double tap to wake support because the code is only compatible with xperia z and zl
You won't loose any data just flash it and enjoy

Select the maximum frequency 702, 810, but after restarting it still exhibited in 1512. Minimum 384 and held.

Bro use the synapse app to configure CPU frequency in msm limiter for each core or off the msm limiter to change frequencies from any app the link for synapse app is there in op

And about recovery in it?
I dont see download link
Thank you!

it's in download section up there @uncomment

Sorry guys forgot to add the link for synapse app to configure msm limiter now it's there in OP

does not work for me gamma control...

the kernel seems to be working fine im using trickster mod because i cant use synapse it says device not supported i tried everything in the synapse thread
is there an easy way to make synapse work?

brightness level different. there is something weird.

[KERNEL][UNOFFICIAL]Custom Kernel v1

First custom kernel for grand prime.
Features:
Disabled "Samsung features"
Fixed and optimized compression XZ
XZ compression is used for the ramdisk (should increase the speed of processing)
Added function sweep2sleep
Two new CPU frequency (1152MHz and 1209MHz, is not working, the problem is known, in the near future will be fixed)
It uses the new driver Wi-Fi (glitches should disappear with Wi-Fi)
Flash via recovery(TWRP, CWM)

I have some problems with the stock kernel I be glad if you can solve it on your custom kernel.
1st. why is the idle frequency @ 800mhz? should that be the lowest available frequency which is 200mhz? or is 800mhz the optimal frequency for battery life and performance?
2nd. About processor. Freshly reboot only one core is online the other 3 offline but after some heavy usage 3 cores are online and only one core is offline sometimes all cores will be online. Rebooting is the only fix so that the other 3 cores will go offline. is this problem related to mpdecision or is it a kernel bug? why are the cores staying online? it causes battery drain. Samsung should fix this.
3rd. Can you include other cpu hotplugging please?
4th. Overclock and custom voltage?
thank you and I appreciate your work.

you should check grand prime's kernel. I'm using cpu-z to check frequencies. I'm ok with 800mhz idle frequency as long as it doesn't make all cores online all the time which causes battery drain. I think it is a bug on mpdecision. if you can implement other custom hotplug like intelliplug i'd gladly appreciate. I tried different stock firmware but the same problem. Maybe it will be fixed when the lollipop update comes.

Hi there,
Please don't release it yet in the new thread on XDA because this is in the development process there are lots of bug right now, would be better to post it in here to avoid bricked phone on newbie
Also you aren't provide the original kernel source & credit!!

Working great, but you need to add the option to activate and deactivate the sweep2sleep option, because interfere with my lock screen, especially with lock screen gesture(using hi locker)give that option to activate it with a kernel manager like Trickster or any other,everything else seems ok at the moment, using it for 2 day.

Thank you bro..please add
1.init.d support
2.sweep2wake
3.knock knock to lock and unlock
