[AKT] Advanced Kernel Tweaks v1.6 FINAL | Insane Battery & Performance(SD820/1|OP3/T)

Update : Nameless Profile V4 for OP3

*Set asynchronous read/write timeout to 7500 ms in zen while reducing the synchronous values to 250 (can expect slightly better battery life due to slightly reduced overhead)

*Fixed scheduler path errors

Guess balanced profile is almost perfect (atleast to me)

New : Nameless_Battery_profile

#Nameless battery is a battery oriented profile focused on reducing current draw and CPU spending lesser times on frequency with higher voltage ratings
#This also tweaks the IO scheduler to reduce the foreground I/O disk access thereby reducing the overhead
#Default cpu enter load for the built-in hotplug is tweaked so as to give big more time to enter the scenario rather than the usual
#Target_loads reworked in a way that the big will use frequencies above 1.2 Ghz if and only if absolutely required
#Other tweaks from Nameless Balanced remain unaltered

I am observing lots of profiles including tunnings for /sys/block/dm-0/ or /sys/devices/virtual/block/dm-0/ but when I tried to navigate to those path there is no such path

Would this be considered as applied setting? Sorry new to ex kernel manager used kernel auditer till now.

I guess it if for encrypted devices

Thank for fast response

@Senthil360, @Mostafa Wael
can anyone explain tuning under this path - /sys/module/msm_performance/parameters/

@Mostafa Wael Have you noticed performance to be better with cfq or zen? (Performance meaning responsiveness and smoothness. Don't really care about benchmarks)

Can we use the balanced profile for gaming as well? (Would you consider the balanced profile an improved version of stock interactive so that we could use it to save some batteries in light tasks but be able to play some games when it's needed? Ty for your support

Zen is based on deadline(additionally merged some stuffs from noop).
I see no fundamental difference between deadline and zen that would make any noticeable difference.
Now I would guess that the author decided to opt to base on deadline since Canonical and other desktop Linux distro makers switched to deadline on SSDs.

However, deadline and noop is not optimized for Android.
Too un-optimized that it's painfully slow once there is a single background write ongoing.
iirc, I even excluded those from the benchmark to make the video shorter.

You would be much better off just with stock scheduler, which is CFQ, and which is surprisingly very fast on Android.

There are other I/O related changes on my kernel that would make more sense/difference in terms of performance like sdcardfs and UFS tunable changes.
