Nephilim's Custom Kernel Settings
- Thread starter Nephilim
- Start date
On TinyKernel high RAB causes slowdown. I've reverted to default settings for that kernel:
-Read ahead buffer size: 256
-Scheduler: cfq
I myself have issues the moment I use a higher RAB. Call it placebo but as long as I have it at 512 or lower I don't get SOD or lag when trying to unlock the screen. I'm not into heavy customization when it comes to undervolting, as old as this phone is battery life is the least of my worries. Screen burn in is the worst on this device lol

I've been using LiquidSmooth for months and love it.

That you'll have to research on your own. Remember this is a kernel settings thread.

Been playing around with Metalspring's SmittyV v2 kernel for the last 6 or so hours, testing out PegasusQ governor with some experimental custom control tunables...........
Alright guys, if you are using Metalspring's SmittyV v2 kernel here are the PegasusQ governor control tunables I've created:
cpu_down_rate: 15
cpu_up_rate: 10
down_differential: 8
dvfs_debug: 0
freq_for_responsiveness: 350000
freq_step: 45
hotplug_freq_1_1: 450000
hotplug_freq_2_0: 300000
hotplug_freq_2_1:450000
hotplug_lock: 0
hotplug_rq_1_1: 275
hotplug_rq_2_0: 275
hotplug_rq_2_1: 200
ignore_nice_load: 0
io_is_busy: 1
max_cpu_lock: 0
sampling_down_factor: 2
sampling_rate: 50000
sampling_rate_min: 10000
up_threshold: 80
up_threshold_at_min_freq: 190000
This kernel absolutely flies, this is the fastest and smoothest my device has been in a long time, battery so far is great as well! All other settings are the usual SmittyV/DirtyV settings I have posted in the OP. Enjoy
P.S. These settings are just numbers picked at random as usual.

Thanks @Nephilim for taking the time to randomly pick numbers for us. I mean, ANYONE could have done it, but you stepped up once again. [emoji6]

up_threshold_at_min_freq??? is that a typo? coz tock value is just 85
btw the problem i mentioned with pegasusq for me is gone after applying these settings

I'm assuming you were researching old threads about PegasusQ. 190000 is the lowest value that can be set as of this version.
Sent from my Android 4.4.2 Galaxy Nexus
up threshold is set to 80
afaik up threshold at min freq should also be a value and not freq, also i cannot enter 190000 there in synapse as soon as i press done the value reverts to 85
what i think is min freq at up threshold may be 190000 but its not here

**These settings are meant for 4.2.1, 4.2.2, 4.3 and 4.4 kernels that I specify, the tweaks to certain areas however should work on more than just the kernels I include in this thread.**
Hey guys, as most of you from the AK Kernel thread may know (or now the DirtyV Kernel thread) and a few others that checked my signature links, I take great pride in customizing the best possible kernel settings for excellent performance and great battery, Since we've moved on from Android 4.2.x based roms and Stefano (AK) has since moved to the Nexus 4 I have been trying out other kernels, this means new settings to tweak and improve.
This Thread is dedicated to the custom kernel settings I use with some of my favorite kernels, I will still include my AK Kernel 4.2.1/4.2.2 settings but in addition I will be adding some new settings for a few kernels I think are quite impressive. Feel free to ask any questions you like, take from my settings what you like and answer anyone elses questions that you may know the answer to. I want this thread to be a community of help and not just from me. I do not expect you all to use my custom settings exactly, if you want to experiment feel free to, these are just a base to start with if you are not familiar with tweaking kernels and for those that are and enjoy my settings/colors, feel free to use them as they are.
The 4.4.x kernel settings will be occasionally updated if and when I feel there are improvements worthy of making so keep an eye on the thread for information on changes that may have been made to the OP.
Section 1.4.2.1/4.2.2 Based AK Kernel Settings:
Section 2.4.3 Based Kernel Settings (Should work on 4.4 roms as well or have a 4.4 variant):
A.S.K.P. Kernel:
Golden Kernel:
Tiny Kernel:
DirtyV/SmittyV Kernel:
I have no lag, no freezing, good battery life and excellent performance with these settings
Also, my ram sits at between 234mb and 145mb free on AK, ASKP and Golden kernels and between 355mb and 270mb free on Mpokang, DirtyV and Tiny kernels due the BIGMEM on Mpokang and DirtyV and ASRAM on Tiny. I have 128 apps installed.
My battery stats are as so, on low usage I get about 21hrs to 23hrs of standby and 1.5hrs to 2hrs of on-screen time. On normal use I get about 15hrs to 17hrs of standby and about 2hrs to 3hrs of on-screen time. On heavy usage (which is only occasional) I get about 11hrs to 13hrs of standby and about 3hrs to 4hrs of on-screen time. Take into consideration, these battery stats are from a Toro Galaxy Nexus, this means those of you on a Maguro (GSM) model will probably get much better battery life than even this by using my settings.
Section 3.
Jellybean/Kit-Kat Minfree Settings:
(Be advised, you must have the Donation version of Trickster Mod in order to add minfree settings)
Section 4.
Lollipop Minfree Settings:
(Be advised, you must have the Donation version of Trickster Mod in order to add minfree settings)
Color Settings:
My color settings work with any custom kernel, I feel that they have a remarkably crisp and vibrant tone to them, feel free to use them and tweak them as you see fit.

basically the 3 are the same , the biggest differences are the amount of ram available to the system . the nexus allocates ram for the camera to use , but it was discovered we can change the amount without affecting camera functionality . smittyV is the kernel that I personally use . it's normal ram , dirtyV is the main kernel , it has more CPU governors than my version , and the dirtyV-SR version has the most available ram but breaks 1080 recording and video playback . so its up to you which to use .
ART is a replacement for the dalvik just in time compiler , its a bit smoother , apps open faster , and it will be the default run-time in the next android version . you can find the two under settings/developer options .
f2fs is a filesystem , like ext4 , NTFS , etc . it is supposed to be made specifically for solid-state drives and flash memory . currently for the gnex its new and not as polished as ext4 , but it does make a bit of difference combating lag during play store installs and other things. be warned , to use f2fs you must format your phones storage , so you will lose everything if you don't back the data up on your computer or somewhere else . I'd say hold off on f2fs until your a little more "seasoned" at the phone customization .
hope this helps a little , and welcome to the fun stuff [emoji3]
Hack the Tuna11**DIRTYV UPDATE**
*Changed I/O Scheduler from Noop to Zen, I/O Tunable Settings Are As Followed:

rotational: 0
rq_affinity: 2
async_expire: 2500
fifo_batch: 0
sync_expire: 304 (won't allow me to set 300, which was my original choice, really don't think there is a difference though lol)
Thanks,
