Changelog:
#2
* Conservative set as the default governor - gave it 10k sampling rate like I did on Ondemand and gave it a 80 up_threshold, a bit lower than the stock value. This will make the governor scale up a bit more often, making the system a lot snappier while maintaining a good battery balance
* Added SLQB memory allocator - I usually tend to use SLUB, but I decided to give this one a try this time and it proved to be a great choice
* Dynamic Hotplug disabled - we want the system to have both cores always enabled. This means two things, means it will help a lot for the race-to-idle (the fast we go into idle the more battery we can save), and it means the amount of overhead that was created during onlining/offlining cpu1 is gone since hotplug is a very costly process to the system
* Power Management patches from the mainline kernel
* EXT4 driver patched up a little bit
* EXT4 write performance regression fixed (regression is when a newer introduced code f*cks up, unintentionally, some other code, in this case the regression was fixed)
* Lowmemorykiller driver patched up for a better memory management
* Sleep of death issue should be fixed
* Introduced VMAP_AREA_CACHE - for more information visit this old commit from me (commit)

他的kernel快和省電最主要的原因
我們絕大部分的人都認為只要在CPU1沒用到是的時候把它給關了就會省電，殊不知原來這一開一關會給電池造成負擔
我也快棄abyss不用了，現在要轉碼頭了

早上才刷abyss 3。8，先用一两天看看才来刷franco kernel。。。
如果2nd core直接set dual core不懂会不会也有同样的效果？

你去看他的帖，得到好評還不止，最重要的是他本身用了note 30hrs就把v1搞定做出來，之後收集意見改進bug, 今天又再次發布v2, 我看好他是因為他的研發改進速度，以及他本身擁有一台note, 這些林林總總加起來，絕對會比abyss強

也许是好事。不用烦过渡UV弄到note不稳定。也不用和人家比较谁UV比较低。
最重要不用再set来set去！ 最重要是快！

刷了franco kernel v2，感觉比abyssnote顺多一点点，暂时不会SOD，接电话后也不会黒屏，standby时的温度比abyssnote热2-3度，但是玩game时却比abyssnote少2-3度。

靠近他的話要小心

都死光的話他的一個大馬保健計劃就沒人參與了
所以賤民是很重要的

GOVERNORS
Ondemand:
Default governor in almost all stock kernels. One main goal of the ondemand governor is to switch to max frequency as soon as there is a CPU activity detected to ensure the responsiveness of the system. (You can change this behavior using smooth scaling parameters, refer Siyah tweaks at the end of 3rd post.) Effectively, it uses the CPU busy time as the answer to "how critical is performance right now" question. So Ondemand jumps to maximum frequency when CPU is busy and decreases the frequency gradually when CPU is less loaded/apporaching idle. Even though many of us consider this a reliable governor, it falls short on battery saving and performance on default settings. One potential reason for ondemand governor being not very power efficient is that the governor decide the next target frequency by instant requirement during sampling interval. The instant requirement can response quickly to workload change, but it does not usually reflect workload real CPU usage requirement in a small longer time and it possibly causes frequently change between highest and lowest frequency.


Conservative:
A slower Ondemand which scales up slowly to save battery. The conservative governor is based on the ondemand governor. It functions like the Ondemandgovernor by dynamically adjusting frequencies based on processor utilization. However, the conservative governor increases and decreases CPU speed more gradually. Simply put, this governor increases the frequency step by step on CPU load and jumps to lowest frequency on CPU idle. Conservative governor aims to dynamically adjust the CPU frequency to current utilization, without jumping to max frequency. The sampling_down_factor value acts as a negative multiplier of sampling_rate to reduce the frequency that the scheduler samples the CPU utilization. For example, if sampling_rate equal to 20,000 and sampling_down_factor is 2, the governor samples the CPU utilization every 40,000 microseconds.


Performance:
Sets min frequency as max frequency.
