July-30
* Updated to latest NG2 source from Samsung
* Updated kernel to Linux 3.4.100
July-19
* Cleaned up cpu frequency table, 2899Mhtz was never a valid freq, and the new ones were based off of that step. That is now fixed
* Bumped bandwith on 3 highest freq steps
* Bumped max voltage to 1400
* I/O: deadline: Allow 0ms deadline latency, increases the read speed
* SELinux: Fix memory leak upon loading policy
* msm: kgsl: Fix nice level for higher priority GPU start thread, previously we were using the lowest possible process priority which increase latency, (cherry-picked from flar2's HTC One-M8 kernel)
* PM: devfreq: Use high priority workqueue. Same thing as mentioned above, give the GPU freq driver higher priority (flar2)
* A couple misc. I/O related patches from upstream CAF kernel
* Updated to latest NF6 kernel source from Samsung
* removed more log span (ktoonsez)
* added nightmare cpu governor
* tweaked some ancient configs for intellidemand back from the msm8x60 days
* added frandom support if there is anyone who uses it
* Added sysfs module to enable/disable fsync (enabled by default). It's in the standard location (/sys/module/sync/parameters/fsync_enabled) and like always can be configured though the chronic-config.sh script. I can also personally vouch for the tack that tricksterMOD will show the FSYNC enable/disable toggle with this patch. So any other app with the option should as well
* cleaned up chronic-config.sh and added missing cpu governors to list
July-17
* Added ability to overclock CPU to 3.01Ghtz
July-13
* Chronic Hotplug is born! This is basically based off of ktoonz KT auto hotplug but with user configurable parameters. Right now all you can change is the "enable_core_thresholds" this is the load the system has to be at for each respective core to turn online. the number is % of cpu load time 10. So 30% would be 300 (0 = always online). There is one module called enable_core_thresholds that sets all four cores. Its formatted like this (0 240 290 390). I have added an option in the chronic-config.sh script to configure this. Here is an example showing cores 0 and 3 always being on and 1 and 2 to come on at 24% and 29% respectively
Code:
ENABLE_CORE_THRES="0 240 290 0"* Disabled userspace mpdecision since we are now using Chronic Hotplug
* Also added option to set I/O scheduler in chronic-config.sh
* Backported some upstream 3.16 scheduler updates
July-10
* Reverted some of the sched tweaks merged from faux's kernel to vastly improve I/O performance
* Disabled some more debug options we don't need to speed up the kernel
* Switched back to Gzip compression as we have the room and kernel will initialize faster
* Set net loopback default mtu to 64K
* Fixed simple-ondemand gpu governor from crashing (ktoonsez)
* Reverted DRIVERS: SLIMBUS initial overclock commit as it seemed to drain battery when playing music
* Removed async-fsync for now until I make a module for it. Like another user said, I didn't notice any performance decrease with it off.
* Removed F2FS as i'm pretty sure its only compatible with AOSP (If i'm wrong let me know and i'll merge it back)
* Further tweaks to thermal (kthermal) values to be more stable on high frequencies (dropped polling speed to 500 ms and lowered temp limits about 2 degrees
* Disabled KT-auto-hotplug code i forgot about since I don't support it
* Stopped Samsung's "cpufreq_limit" driver from overriding Max freq (note: I had the option of stopping it from changing the min freq but it drastically decreases performance. This is equal to the cpu-boost and DVFS driver on the S4. They just expanded it to include a max freq cap which i disabled so we are not limited by it, So bottom line. You can set your min freq/ but it is temporarily overridden by the driver at times. THIS IS NORMAL AND IS LIKE THIS IN ALL KERNELS EXCEPT I ACTUALLY DISABLED THE MAX LIMIT SO IT STOPS GETTING LIMITED AT 1.19GHTZ AT TIMES. THIS IS THE OPTIMUM SOLUTION
* Fised chronic-config.sh not copying to the devices
* chronic-config.sh: fixed path for GPU max freq
* Set GPU min freq to 320mhtz (Samsung default) and added an option in chronic-config.sh to change it
* chronic-config.sh: list all available cpu frequencies instead of just a range since they are hard to remember
July-5
* initial release *
Some noteworthy changes from original source not listed above...
* Got rid of some logspan.
* send input events one at a time (faster touchboost related responses)
* few mismatch derps by samsung (faux123)
* Few other small fixes
* ]If you have problems with frequencies sticking use "System Tuner" and go to Settings and prevent other apps from changing CPU settings
* ]If you have problems with MINIMUM frequency sticking the reason is because of the touch boost driver. when you tap the screen you can't go below 1.19Ghtz, hence whenever you set a min freq....The only real solution to this without disabling the touch boost driver which hinders performance is to use the chronic-config.sh script or have an app set it boot. basically be set without a tap on the screen
* Although this kernel has now reached "beta" status. bugs still could pop up. please if you find a reproducible bug and decide to post please try and provide a last_kmesg or logcat.

* ktoonsez, this is a major fork of his kernel!
* First off of course cyanogen, the CyanogenMod project and all who contribute.
* A lot of this was taken/based off of flar2's Kernel for the HTC One, so thanks for the source!
* Also grabbed some things from Faux123's kernel
* All the people who have helped me learn more and more over the past year and a half
(arco/dastin1018/android1234567) you guys are the best!
here is a donation link if you want to buy me a coffee or pack of smokes (I go through a lot sitting on the PC messing around lol) go ahead. But not required or expected by any means
Note: The name on the paypal account may say patricia, this is because it's a family paypal account.
Happy Flashing
