- Portet Ezekeel's Touchwake Feature (from nexus s)
- Oc up to 2 Ghz
- using Joe RCU
- Backport from Linux 3.5 smp driver parts
- Cm Wifi driver (from D2 Linux 3.4 kernel)
- possibility to set high/low power mode for wifi when screen is off
- LulzactiveQ cpu governor (from siyahkernel, thx again to Gokhanmoral)
- Hotplug Cpu Governor
- Proportional Rate Reduction for TCP
http://kernelnewbies.org/Linux_3.2#h...7963f165302b6e
- improve memcopy/memmove
- Using Voodoo Sound
- mdnie: toggling mdnie negative effect with home button (Gokhanmoral)
- Reverted LED Control

Kernel app (alpha stage): http://forum.xda-developers.com/show...3#post41346443

For setting up the Kernel features (till my app is finished), I recommend using Trickster Mod (free)

Dualboot Faq:
For more detailed instructions, please take a look at this thread from RichMd (thank you for it):
Dualboot Faq thread

Important: if you want to use this kernel for dualboot, i highly recommend flashing my recovery as well.

General information about the recovery:
- the recovery does not mount /cache, /system or /data by default. if you want to perform any file modifications to either of your roms (wiping data, create/restore nandroid, fixing permissions,...), you have to use the dualboot menu before.
in this menu you can:
* create the secondary system partition (needed to be run once, if you want to install a second rom)
* enable mounting of primary filesystem
* enable mounting of secondary filesystem
if you have enabled the mounting of one of the filesystems, all the actions mentioned above are performed to the filesystem you selected. this filesystem stays the active one, unless you reboot to recovery, or you select the other one.

Install-zip menu:
you'll notice there is a new menu, where to select what you want to flash.

• if you select kernel, rom or recovery, the zip gets installed as it is.
• if you select zipt to pri./sec. filesystem, it is selfexplanary
• if you select rom to secondary fs, the zip gets modified to install to the sec. fs. IF YOU WANT TO INSTALL IT TO PRIMARY FS LATER SOME TIME, YOU NEED TO REDOWNLOAD THE FILE!
• if you select rom to primary filesystem, it gets installed there, and you can use the same zip later again.

How to install a second rom:
make sure you have already created ssecondary system partition! if not, go to dualboot menu and create it now (this may take some minutes)

• The savest way is the way by using nandroids: if you don't have a nandroid already, create one now. Go to dualboot menu, enable mounting of primary fs (look above for details), go to nandroid menu and make your nandroid.
  go back to dualboot menu, enable mounting of secondary fs, then go to nandroid menu, and restore your backup.
  you now should already be able to boot into primary or secondary rom (which are both the same now).
  now you can install any other rom as primary.
• if you want to install a new rom directly as secondary,
  make sure there are no spqaces in the filename!,
  then just go to install zip. you'll notuice there's a new menu at some point.
  in this menu you can select where you want to install, and what type of file it is.
  if you choose rom to sec. fs, your zip files itself gets modified to be installed to secondary fs. this may take a minute, because the files needs to get zipped again. Imporant: this file is permanently modified. if you think you need it later again, you should redownload it, because the modified one would always install as secondary.
  installing a rom as primary, a zip to primary or secondary fs, does not modify the zip.

Additional information:

• roms coming with an aroma installer are hard to handle, as every dev can place own commands into it. It's impossible for me, to take care of every possibility. Because of this, it should be the best method, to flash a rom with aroma installer as primary one (and then move it to secondary, by using the nandroid method, if you want it to be secondary).
• mtp not working properly:

Changelog:

12.06.2013
- linux 3.0.81
- fixed internal storage on 4.2.2 secondary roms
- reverted cpufreq driver back to "default", to try fixing being stuck at max. freq for some users

06.06.2013
- merged update9 changes from cm team
- wifi changes which hopefully reduce wakeup time
- built nfs as module (was built-in before)

29.05.2013
- update to linux 3.0.80
- reverted a commit from 3.0.79 which caused the cpu to be stuck at max. freq
- fix touchwake/proximity sensor for i9300
- cpufreq: fix handling of offline cpus
- dynamic fsync: fixes from faux123, to prevent data loss, in case of kernel panic/unexpected shutdown
- CPU hotplug, writeback: Don't call writeback_set_ratelimit() too often during hotplug (from francisco franco)
- freezer: allow tasks to be frozen faster (1ms if possible, instead of 10 ms)
- freezer: skip waking up tasks with PF_FREEZER_SKIP set, to make suspend/resume more efficient
- t0ltecdma: fixed sprint compatibility

15.05.2013

important: please uncheck in deviltools to apply settings on boot! gpu voltage changes would cause the device to freeze on startup!
- reverted gpu voltage to be displayed as before (this fixes incompatibility with trickstermod or other apps)
- DevilQ: turn/keep second core online on screen touch
- add PM_SUSPEND_FREEZE powerr state (if used, it does save little less power, but PM_SUSPEND_FREEZE has less resume latency

12.05.2013
- linux 3.0.78
- added own cpu governor, DevilQ (based off lulzactiveq by gokhanmoral)
- improved touchwake (acting like swipe2wake now, if delay is set to 0, to prevent false wake ups)
- pegasusq: readd some of andreilux's changes
- gpu: allow oc up to 800 mhz
- added option to disable touch boost
- updated wifi driver from s4 (commit by cm team)
- disabled swap, zram and cleancache

28.04.2013
- linux 3.0.75
- fixed cam preview on note2 lte
- new tunables for pegasusq:
* early_demand: to enable this functionality (disabled by default). ( echo 1 > sys/devices/system/cpu/cpufreq/pegasusq/early_demand, to enable it. 0 disables it)
* grad_up_threshold: over this gradient of load we will increase
frequency immediately. ( echo xx > sys/devices/system/cpu/cpufreq/pegasusq/grad_up_threshold, to set value. xx has to be betwenn 11 and 100, default 50)

27.04.2013
- updated block to linux 3.3
- updated row i/o scheduler to linux 3.4
- added fiops v2 i/o schedler

25.04.2013
- readded gokhanmorals sammy/aosp mod more cleanly
- lulzactiveq: small fixes
- cpufreq_pegasusq.c: revert to stock
- Enabled AIO support
- improved aio: Asynchronous I/O latency to a solid-state disk greatly increased between the 2.6.32 and 3.0 kernels. By removing the plug from do_io_submit(), we observed a 34% improvement in the I/O latency.
- added zzmoove governor

- Andreilux:
* mdnie-control: Digital brightness control
* s6e8aa0: Allow manual brightness to 300 candela
* ARM: decompressor: Enable unaligned memory access for v6 and above


19.04.2013:
- Fixed patch: "LOAD_FREQ (4.61 s) avoids loadavg Moire (thx to Klaus Ripke)", many thx to AndreiLux for pointing and fixing this
- Added Franciscofranco's Touch Boost Control (input boost frq., when screen touched can be set with trickster mod app), including the additions from simone201, but fixed to not beeing stuck at high freq.
- removed LCDFreq scaling mechanism (using touch boost instead)
- fixed charging while device off
- applied a bluetooth patch from cm (might help with bt issues some users were reporting)

more to come ...

hints and fixes:
- if your pc does not recognize your phone, please try this method, until i know what is causing this behaviour:

The t0lte kernel is just 116kb? Hmm, weird.

Edit: It is 7.7MB now, I guess you were still uploading it since it was showing 116kb, it's all good now, no biggie

I just have downloaded it with my note, and it is 7,some mb.

Please try downloading again

Aosp and Sammy at once means it's truly dual boot am I correct ?

not yet

just flashed it on tmo note 2...voodoo sound app says kernel didnt support it

also..kernel version is listed as "unavailable"

No it means universal kernel, which means possibly big options in future releases.

Hey how is this I think I am going to flash it but debating on a phew right now

Everything working nicely for N7100 version on TW rom. Is it possible to add features like swipe to wake.
