Thanks to:
SebastianFM, showp1984, simone201, franciscofranco, Ezekeel, faux123, arkusuma, aftersilence and all guys how are involved in development on many different platforms
Installation:
1. Use fastboot mode to flash boot.img
2. Copy all modules to \system\lib\modules
Good lecture about governors and how to tweak them[/SIZE]
http://forum.xda-developers.com/showthread.php?t=1369817
Changelog:
07.31 R00 initial version
08.01 R01 new govs: lagfree, smartass2, lazy, interactive; arkusuma's touchscreen driver mod updated (now you can customize it by yourself)
08.02 R02 undervolting fixed, LMK from kernel 3.4, 2D GPU scaling to save some juice, and other minor patches
08.04 R03 smartass tweaked a bit, new CPU OC steps (1,9 Ghz max), GPU 2D/3D OC, second core behavior fixed (it was ramping up to the max no matter what was set as max freq), recovery version thx to aftersilence!
08.07 R04 new governor: badass with two steps at 1188000 and 1512000 and tweaked for performance , fsync control, autobrightness driver: it reports now 6 levels but we need to edit framework to use those new levels
08.15 R05 updated to 3.0.40 plus some "under the hood" fixes
08.25 R06 clean start with all previous features on 3.0.41 base , i hope that i got rid of all those nasty random reboots (voltages are little bit higher on default), no CM9 support - its good enough on its own , fastboot version only (due to problems with recovery update script) , JRCU, autobrightness levels reworked once again, CAF patches
09.03 R07 cpu1 stall at 1,2 ghz fixed, CAF patches to gpu,videodecoder, hdmi, and framebuffer
09.05 R07_1 dialer reboot fixed
09.12 R08 LMK updated, kernel base updated

does it provide better battery life?
i don't now, i didn't test battery life that much
but higher cpu clocks usually means shorter battery life
Looks good. Can you add this to your kernel? http://forum.xda-developers.com/showthread.php?t=1792713
//ok sorry I didn't see it
it's already there:
-arkusuma's touchscreen driver mod
Already tried that! Mass improvement!!!
Thank you for the great work! Keep up that way and make MediaPad even better!
Tnx dude! Works, and looks fine!

can you explain better what do you mean for "mass improvement"?
thanks
can i specify value for last mod of "touchscreen filtering" on this kernel?

If I tried to change the VDD with system tuner, it automatically jumps to 1350mv and stuck at that voltage.

PROBLEMS
-native WIFI Tehtering doesn't work -> blame Huawei for obsolete Wifi driver (on stock kernel too)
-there is no source for huawei's wifi driver so i needed a hack to make it work
Customization possibilities are a little bit limited because of this

You have right It's broken I will try to fix it
While you're at it, can you change the value of touch_thres in touchscreen mod for the default 10 (or 9?) to 25...or 20. Better yet, ask arkusuma for his latest mod where it's user adjustable

BCM4329 is actually the old driver. With ICS google introduced new bcmdhd driver
Huawei was so lazy and took old gingerbread driver, that's why thetering don't work
maybe you can add in some additional governor.

That's a good proposal!
I use S7-302u ,Android4.0.3,C232B001.
Can i flash this kernel ?
thank you for advice.
nice work, sounds good.
My Mediapad doesn't work with my Nikon D7000 DSLR together. (If I plug a Canon EOS in (which works), the D7000 works afterwords with DSLR Dashboard, Helicon Remote,... until I reboot my tablet again)
Sound strangs, I know! ^^ (But the D7000 is recognised always @ USB Host Controller and also at dmesg)
Maybe this kernel will help me!
Sorry, but I'm a newbie in generell (@ Android):
I tried already some firmwares to solve this, but only with the SD-card, which isn't very hard to do.
Can you make a more detailed install instruction?
With which firmware I can use this kernel mod?
many thanks

according to this
http://forum.xda-developers.com/archive/index.php/t-1743025.html
there is no difference between those two versions so i think you can safely flash the kernel. If it's for whatever reason not gonna boot up you can always revert to original kernel

If you are on newest Android for Mediapad (ICS 4.0.3) you can flash the kernel
but i really don't now if its gonna help with your problem. I haven't touched USB part in the kernel (apart from regular linux kernel update)
To flash you need to use fastboot mode and those two commands
fastboot flash boot boot.img
fastboot reboot
To boot into fastboot just install Quick Boot from Google Play and choose Bootloader there
NOTE:
I'm not a DEV and not pretending to be one, I'm a android enthusiast.
I would like to thank all XDA members that are helpful.
I build and mod stuff for my personal needs and then I share them.
Do I want something in return? NO.
You don't like it, no problem, there are enough good DEV's with there kernel to help you along

Samsung Error fixed
Hopefully support for GT-N5100.
CivZ-StormBorn-Rev2.0 (07-Jul-2013)
One kernel to support GT-N5110 & 5100.
CivZ-StormBorn-Rev2.0 (09-Jul-2013)
Separate kernels for 5100 & 5110 due to ramdisk changes between them. (Problems with Stickmount & USB OTG so I had to make two different kernels , zImage is the same but the ramdisk is different.)
So it still chows 2.0 in settings as nothing changed in the zImage (boot.img = zImage + ramdisk)
CivZ-StormBorn-Rev2.1 (11-Jul-2013)
3GUSB Dongle support when connected with OTG usb cable with the PPP-Widget
Connect to the internet without a wifi connection.
Just set your APN in the widget and connect it, it works fine with my Huawei E1552 3GUSB dongle
This is a nice option for people that got the GT-N5110 wifi only but I think even people with the GT-N5100 can use this option.
CivZ-StormBorn-Rev2.2 (15-Jul-2013)
All modules removed and all features build in to kernel : cifs , ppp 3Gusb support, ufs,....... No more messing with loading modules.
Read time of bad quality SD cards increased.
25/08/2013 Rev1.4 released.
ExFat support , compiled from source
Realtek RTL8192CU/RTL8188CU USB Wireless Network Adapter support
Ralink driver support : Ralink rt2500 (USB) / Ralink rt2501/rt73 (USB) / Ralink rt27xx/rt28xx/rt30xx (USB) /
rt2800usb - Include support for rt33xx , rt35xx , rt53xx
Atheros Wireless Cards support
DOWNLOAD AND INFO IN OP
Note on GPU clock:
Trickster shows more selectable frequencies but you will notice that when you leave the app (back button) the max clock will always be 533MHz even if you selected 700MHz.
I did not eneable higher clocks as I still need to figure it out , I got a test kernel with higher clocks but I don't see any real performance difference so I don't make it public now.
Result at 1.9GHz

Thanks for sharing so you said no OC for now, is this kernel good for better battery life?
Thanks civato, it works for me. I tried cifs mount to samba server - good. Androbench reports huge improvements in I/O so fsync must be working right. Cheers
Booted great for me too. I reverted because my init.d is customized already and one of my scripts wasn't running, but wonderful to see.
My wish list for kernels includes undervolting before it includes overclocking, especially with performance enhancements in i/o coming online.
I applied the i/o script in the toolbox forum earlier today and at least benchmark performance jumped. Not sure about overall system response yet, not that much time with the toy today

No dynamic fsync is off by default, you need to enable it with terminal command. See op on how to.
Your I/O score is higher then stock because of the init.d tweak included.
dynamic fsync, what is this?
gesendet vom Galaxy Note 8.0
I eventually sorted out the problem I was having with my init.d script.
The new kernel identifies the sdcard differently. The stock kernel refers to
/dev/block/vold/179:17
the custom kernels need to be told that it is
/dev/block/vold/179:49
Folks who are rebinding their SD cards to extend their storage should keep that in mind.
Once I'd ironed that out, I found that the system was using more cpu at idle than it had been. Using governor tweaks (mostly around the "ignore nice" setting) my cpu idles at 200-300 mhz quite a lot of the time.
I saw a lot more spikes to 1.4-1.6 ghz with the new kernel.
I suspect that's a result of the different superuser more than anything else, but I ultimately reverted back entirely.

I don't know what governor tweaks you use but mine idles at 200MHz and only jumps to max when needed.
My battery life is normal and nothing higher then on stock kernel.
I didn't even change anything regarding this in the source.
With dynamic fsync on, approx 3x improvement in sequential write:

PS:

I'm currently running happy at a 75 mvolt underclock, and if this proves stable I'll probably try for a 150 mvolt next.
Thank you very much for providing a kernel that supports undervolting!
I use two init.d tweaks. One chanages the frequency step from 37% to 5% - I'm trying to get the processor to step up in 100 mhz increments, rather than jumping from 200 to 800 and on to 1400 quite so much.
I'm also using "ignore nice load," so the processors ignore niced processes when counting their backlog and deciding whether it's time to increase clock.
I wasn't (and don't) think that there was anyting in the kernel that was making my system idle at higher load.
I do think that the superuser that got installed with your binary was doing more work than the su's I'm used to working with, since it was offering to ask again in 15 minutes after the grants of privilege escalation.
I ultimately fixed it by extracting the boot.img file from your package and just flashing that, then adding the modules and init.d scripts in root explorer, and putting back my preferred superuser.
I'm currently running happy at a 75 mvolt underclock, and if this proves stable I'll probably try for a 150 mvolt next.
Thank you very much for providing a kernel that supports undervolting!
One thing that is odd on this guy - when I undervolt, many but not all of the voltages take. There are a few of the voltages that it seems Samsung really, really wants to have a little higher, especially in the 200 / 400 / 600 mhz range but some up higher than that.
when will be kernel available for N5100? wlan version is boring
the first rule of kernel club is you don't ask for deadlines in kernel club.
Now we all get to hang out at your house and drink beer forever. Except you. You have to get a job to support us.
Big thanks, 1.1 flashed - all looks good to me.
info next update
Some info on next update.
Rev1.3.
Redid the uv so it works on all frequencies correctly. Meaning the lower frequencies.
I added new lower frequenties 50 and 100 MHz.
Over clocking up to1800 MHZ, maybe 1920 if I get it.
boot up speed is 200 and 1600 MHz , if you want lower or higher speeds you need to set it.
Enabled arch power and some more optimizations.....
release today or tomorrow.

Usage of some features
Dynamic management of dirty page writeback
What is does?
- Allows to dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off. By using a higher interval we have better performance and less battery consumption, with a very low risk of data loss.
Thanks to Christopher83 and kingBABAsula.
Usage-
To enable it:
Code:
echo 1 > /proc/sys/vm/dynamic_dirty_writeback
To disable it:
Code:
echo 0 > /proc/sys/vm/dynamic_dirty_writeback
To customize intervals (in centisecs):
Code:
echo xxxx > /proc/sys/vm/dirty_writeback_active_centisecs
echo xxxx > /proc/sys/vm/dirty_writeback_suspend_centisecs

been using triple recovery on xperia sp.
Will try this one on my xperia P :good:
Nice job ^^
But one question: is this 3.4 kernel, so yes can you make one for JB ?

Great work @Abhinav2! Just a quick suggestion. Maybe you could update the mali graphic driver and/or add OC feature to Cpu (and Gpu if you will)

I tried update mali drivers and gralloc to 6 may update but unfortunately it didn't passed kernel logo. I'll try to debug it but it can take time. Also DevSwift1 tried GPU OC but it had no effect on device.

the first custom kernel for kitkat, thanks AJ!
1. dual recovery seems cool, but imo there is no real benefit when both of them do effectively the same. Again, great job that you managed to include both, but to me it becomes just "bloat". no offence.
2. I'm not a fan of overclocking but there are uses for better CPU/GPU controls. I would love to underclock and undervolt them to squeeze a little more battery out of my phone. God, it seems lots of those kids here care about their "gaming performance" and their "lagfree" "smoothness", but I use my phone as a phone and I don't give a sh... about that if I can get a couple more hours of use.
What's your opinion on this? Do you think we will ever get this working here like all the others (looking at those qualcomms and snapdragons in the other forums)? I mean we got more manufacturer sources than most of them, right? Or does it come down to sacrificing a phone to find those precious values for the right voltages, ...? Please shed some light on this for me, I never read a real answer from any dev out there.
3. On 4.1.2 we had this phantom kernel with a lot more CPU frequency steps. Some governors worked definitely better when they can scale over more frequencies. Maybe you can implement that?

1. Got many PMs asking for dual recovery so included it. And it won't slow down the boot process or make it laggy. Why?
If you extract the ramdisk you'll see that init.sh script controls the booting just like in CM(new builds)/AOSX. What the help of this script, ramdisk and recoveries are separately extracted so it doesn't extract and ramdisk or ramdisk-recovery until and unless the particular key assigned to it is pressed.
2,3. Honestly, I never looked at oc/uc, as I don't like playing with my CPU clock at all. Though I can try to integrate it and can only give a proper answer after trying
Cheers,
AJ
OK guys. I did read about OC CPU and various methods for our devices and basically all the kernels which say having OC aren't properly adding it. What they actually did was just adding CPU frequency names in the table in drivers/cpufreq/dbx500-cpufreq.c. Also it is quite hard(and maybe risky) to OC our kernel since I can't find the OC threshold anywhere. So it'd be better not to bring OC to it.
And about triple recovery, I won't be bringing it in this or kumquat kernel. DooMLoRD said that he wanted to keep it exclusive to DooMKernel and TBH I agree with him. He did put a lot of efforts in it and I respect his decision.
Cheers,
AJ
thanks for the amazing work
Hi,
On my Mido, MIUI 9.0.5.0 is installed. I would like to have a charge more fast : I have see this kernel :
https://forum.xda-developers.com/re...-development/kernel-stormguard-11-08-t3702031
Is the kernel 100% compatible with my version of MIUI?
Is it worth it to change kernel and and what does it bring more than the default kernel?

@physwizz I will continue the conversation about underclocking here instead of hijacking Eureka thread...
You could do a test build with Eureka underclocks and compare the current draw with cpus idling to your present underclocks. There will be a "Goldilocks" point at which it is pointless to underclock any further that is directly related to the 14nm architecture of our SOC.

Sure
What minimums would you like?
@physwizz I don't know what minimums until someone does a scientific test on what minimums yield the best idle current reduction without causing excessive stuttering off the mark....
At a guess, I would be expecting somewhere in the 300MHz range to be the sweet spot.

Are the only ones in the 300s
Next highest are
Big 520
Little 449
@physwizz Unfortunately the comparison between Eureka running at 520 big, 449 small and your 312 big, 208 little is not valid since there are so many differences in the kernels other than the underclock freqs. What is valid is comparing your kernel with the current underclock to the exact same kernel with the next freq up underclock. That would be an almost scientifically valid test.....
