Not any that I haven't failed at so far Lol. I've been trying a bunch of different things

Like what? Kernel tweaks get me giddy. I tried it myself but it's much past what I know how to do
I've tried various methods of trying to get the different GPU OC's into one kernel, I tried lz4 compression for faster boot time, and I tried implementing gamma control. So far I haven't been able to get any of those to work. There's tons of tweaks out there, I just don't know what lots of them are. For example, I keep seeing everyone adding "kernel mode neon" support to their m7 kernels, but I have no idea what it is and have learned basically nothing by researching it.
Any suggestions are welcome.

This is obvious, but I'm sure crpalmer can help. Also the guy who does lean kernel. And Franco. They seem helpful, especially the lean kernel guy. He did good work on the galaxy nexus
Just curious. What would you suggest in terms of Kernel control applications for your kernel? I Normally would use SetCPU or trickster, but what would you suggest?
Honestly probably the best method is to just use crpalmers init.d scripts, but I've been using trickstermod lately because I've been testing a lot of different things.

Yeah I'm gonna start asking for help, I just wanted to see if I could figure it out myself first. I also usually feel like I'm pestering people when I ask for help so I try to do it sparingly

@jamiethemorris Hey jamie, there's a new 4.4.2 ROM out that I want you to try, the new cfX one. The ROM doesn't boot if you flash either the bionic or dalvik libs you made, any idea?
Yeah I noticed that when I tried the ROM last night. Apparently the original moto x dalvik libs don't work either. I think it has something to do with other optimizations they've done. I'm gonna see if I can figure something out
Sent from my Droid DNA using Tapatalk
Its because cfx is using a different compiler so libs will be stored differently possibly :/ You'll need to find where and change where the package flashes them to.
Totally unrelated to the kernel... I never really liked the included android sounds, especially the cheesy song ones. I'm considering creating some custom ringtones and notifications in SuperCollider. Probably wouldn't be music but rather just sounds that I think are cool sounding. And of course I would be releasing the source code for anyone that wants to play with them. Is that something anyone be interested in?

Yeah, that would be nice. I would like to go through it and see what's what and how things work.

For right now, if you want to see how things work I have one of my supercollider projects for school in my github

Awesome tweak of crpalmer's kernel! My phone's running solid at the max 1.89GHz OC as well as the 500MHz GPU OC. It upped my AnTuTu benchmark score from around 17,500 to 20,800 (still a far cry from the 34,000+ my Tegra Note 7 gets, but it's still good for a 1 1/2 year old piece of hardware).
I do have a question... does this kernel not work with ART? I had my phone set to ART, but when I installed this it reverted to Dalvik and won't let me switch back to ART.

It should work on ART. I've run it on ART a few times and I know a few others running it are only using ART. So I'm not sure why that would be happening. What ROM are you running? If you flash back to the stock kernel does it let you go back to ART?

17This is my version of crpalmer's kernel with some additional features:
-Android 5.0 support
-Sweep2Wake/Sweep2Sleep, DoubleTap2Wake (from Beastmode)
-force fast charge (credits to chad0989)
-kexec-hardboot support (for use with MultiROM, credits to Tasssadar for the multirom and the m7 patch I used)
-FauxSound (faux123)
-Moar overclockingz (up to 1890 mhz)
Note: Every chip is different, your device may not support these higher frequencies.
-GPU overclocking (up to 533 mhz) (credits to faux123, )
Note: Again, every chip is different, your device may not support higher frequencies.
-Additional CPU governors and I/O schedulers. Read about CPU governors here.
-Dynamic Fsync (faux123)
-Simple GPU Governor (faux123)
-L2 Cache overclock
-600 MHz bus overclock
-F2FS support (still no luck with getting this fully working, testers are welcome)
-LZ4 compressed kernel (faster boot)
-More TCP Congestion algorithms
-Lots of slimbus improvements thanks to poondog
For maximum performance, I recommend some optimized dalvik libraries (KitKat only):
-For 4.4.4 ROMs, use the "CM11 Dalvik_Final" zip in this post
-For older (4.4.2) ROMs:
If you find any ROMs where none of these zips work, let me know and I will try to make one for that ROM.
I am not responsible for anything that happens to your phone. It is your device and your responsibility.
The following scripts are not required to change settings, they only exist as an alternative for people who don't want to use a third-party app. You can still use your favorite tuner app to tweak most of these kernel settings.
DoubleTap2Wake:
* This allows you to wake the device by double tapping in the bottom half of the screen, just above the hardware keys.
* To enable or disable, create the file /sdcard/jamiethemorris-dt2w
* If this file contains a 1, dt2w is enabled. If it contains a 0 it is disabled. Enabled by default.
Sweep2Wake/Sweep2Sleep:
* This allows you to wake the device by sweeping from left to right over the hardware keys, and sleep the device by sweeping from right to left.
* To enable or disable this, create the file /sdcard/jamiethemorris-s2w.
* If the file contains a 1, s2w and s2s are enabled. If it contains a 0, they are disabled. Enabled by default.
GPU Overclock:
* The GPU's max frequency is loaded from /sdcard/jamiethemorris-gpu-oc. If this file does not exist, the stock frequency of 400 MHz is used.
* To set this GPU overclock, you need that file containing the GPU frequency in MHz. Frequencies from 400 to 550 MHz are available.
* E.g. adb shell su -c "echo 450 > /sdcard/jamiethemorris-gpu-oc"
GPU Governor:
* You can choose from either ondemand, simple, or performance GPU governors. Default is ondemand.
* The governor is loaded from /sdcard/jamiethemorris-gpu-gov
* E.g. adb shell su -c "echo simple > /sdcard/jamiethemorris-gpu-gov"
Dynamic Fsync:
* From Faux123: The dynamic sync control interface uses Android kernel's unique early suspend / lat resume interface. While screen is on, file sync is disabled. When screen is off, a file sync is called to flush all outstanding writes and restore file sync operation as normal.
* Disabled by default. To enable or disable, create the file /sdcard/jamiethemorris-dyn-fsync. Use 0 to disable and 1 to enable.
Force Fast Charge:
* To enable or disable fast charge, create the file /sdcard/jamiethemorris-fastcharge
* Use 0 to disable, and 1 to enable. Disabled by default.
Intelliplug and Eco Mode:
* Intelliplug is a replacement hotplug driver for HTC's mpdecision, Eco Mode limits your device to dual-core operations.
* To enable or disable, use create the file /sdcard/jamiethemorris-intelliplug
* If the file contains 0, intelliplug and eco mode are both disabled and your phone will use crpalmer's hotplug driver. If the file contains a 1, intelliplug is enabled but eco mode is disabled. If the file contains the string 'eco', intelliplug and eco mode are both enabled. Both are disabled by default.
I/O Scheduler:
* To change the I/O scheduler, create the file /sdcard/jamiethemorris-iosched, and your device will use whatever I/O scheduler you specify.
* E.g. adb shell su -c "echo row > /sdcard/jamiethemorris-iosched"
Undervolt Override:
* This allows you to globally undervolt your device, but leave the 1836 MHz, 1890 MHz, and 1917 MHz frequencies at their default voltages.
* To enable or disable:
- First you need to find your PVS bin number. You can find this by checking the file /sys/module/acpuclock_krait/parameters/pvs_number.
- Create the file /sdcard/jamiethemorris-pvs and put your PVS number in that file.
- After a reboot, your device will automatically set the highest frequencies to the default voltages for your chip.
* If you are either lazy or confused, you can put '?' in the file and your phone will set itself to the voltages for a 'nominal' binned chip.
For the rest of the features and changelog, see crpalmer's original cm11 kernel thread.
Thanks: crpalmer for all of his help (before I started on this I didn't even know how to use git), coachcrey for originally inspiring me to do this, and all the other devs/builders here that may or may not know I'm learning from them constantly.

Version Information
Status: Stable
Created 2014-01-28
Last Updated 2014-12-048New Version!
5.5.5:
-Dynamic Fsync (Enable this only if you are sure your device is stable! If you have too many reboots, your data may get corrupted and you will have to reflash your ROM.)
-Simple GPU Governor
-Intelliplug hotplug driver with Eco mode (dual core operations). When this is disabled, it will use crpalmer's hot-plug driver.
-Intellidemand tweaks - I'm still working on this one, it tends to have random reboots at the moment.
-Decrease GPU OC to 533 MHz and increase bandwidth
-1917 MHz overclock is back, should be more stable now
-Sweep2wake + Sweep2Sleep
-Doubletap2sleep is not implemented in this version, sorry. Use your ROM's dt2s feature for now. I do plan on adding this back.
-Doubletap2wake can be used anywhere on the screen
-There should be scripts for all features, let me know if I missed something.
-Undervolt override for high overclocks. You can globally undervolt while leaving 1836 MHz, 1890 MHz, and 1917 MHz clocks unaffected.
-L2 cache overclock
-600 MHz bus overclock for 1674 MHz - 1917 MHz frequencies
-Support for F2FS filesystem (F2FS TWRP and MultiROM are coming as well, as soon as I have time to test)
-FIOPS I/O Scheduler
You guys should notice a drastic performance and smoothness improvement with Dynamic Fsync Enabled5Changelog:
6.0.1
- All updates from CM:
- F2FS updates. Maybe F2FS works now (probably not).
- UID-based routing
- Enable selinux development
- Initial support for Lollipop (KitKat 4.4.4 ROMs are still supported)
5.8.2
- Updates from crpalmer:
* Update some video bandwidth parameters
* Interactive governor updates
- Pretty sure that's it.
5.8.1
- Updates from crpalmer:
* Patched up to linux 3.4.99 (latest version of as now)

-Update modem restart commit from stock CM kernel
-No more intelliplug due to random reboots and the fact that simple plug works just fine. I may bring it back future versions.
-Reduce memory usage of input driver + oom tweaks that theoretically help a little bit with the touchscreen wake issue. I am still working on finding a real fix.
-SLIMBUS: m8 port, caf updates, new OC from poondog (better audio quality)
-Update BFQ to v7r3
-Update to latest F2FS driver
Older versions:

Read an explanation of the new Preservative governor here, by the creator, bedalus: http://xdaforums.com/nexus-4/general/kernel-moob-t2549750/post501734625
Not yet. Thank you, they will be in the next release.
For some reason I'm not having these problems, not sure why.
