rk3188[x7010] - Performance Tweaks, Test Journals, Learning diary, and custom ROM nV 1.03 for x7010
First of all, I wanted to say thanks to LEOLAS of FREAKTAB for all the knowledge I've learned and also for OMA for making his roms PUBLICLY ACCESSIBLE AND FREE!!
PLEASE DO NOT COPY/PAST MY/THIS ARTICLE/POST Without Giving the right credit/Link to this post and XDA Forum too!!!!
I'm A WRITER AND I Dont like PLAGIARISM !!!
although It is fine for me if you will rewrite it in your own words
Oh I will introduce my self first, I am From the Country of [>--] Philippines, though very few developer came from our country, this is because of the LACK of INTEREST / PASSION of most of my countrymen.
I am th3f33, Pronounced as DAFFY or read as The Fee, ayt? xD The real name is Demi francisco, I am a Professional DESKTOP and Laptop Tech, and was used to be my previous work / job. Now I am currently focused on Web Developing and Programming (HTML,CSS,PHP,MySQL,JAVASCRIPT,ETC) that's why I am pretty familiar in the way the ANDROID Language goes (C+,Perl,PHyton,java Ayt?). I AM THE MAD PROGRAMMER!! lol XD (Just like hohouin kyouma).
For the sample/preview of my first cooked rom performance, Here is a YOUTUBE Video for it, stress test in HD Games.... http://www.youtube.com/watch?v=mm1ewtDljuk&feature=youtu.be
Vid is 14 minutes long, it would be better to check this first at least the first 5 minutes, and if you are interested, then you can continue to read.
So the device is:

I AM NOT HELD RESPONSIBILITY IF IN ANY CASE YOUR DEVICE GETS BRICKED!
EXCLUSIVELY FOR Skyworth's Skypad x7010 only, but may also work on chuwi v88 [not tested]
I do provide unbricking service for a fee, but if you will read thoroughly this whole post, you will see the keywords to search for to unbrick rockchip rk30 devices!
DETAILS
I do believe that these tweaks / Performance increase / Speedup can be applied to all RK3188 devices, with the same logic / techniques can also be applied to rk3066 to maximize the performance. BUT BEWARE ON THE RAM(MEMORY) CHIP!!!!
Now here are the information on What i Modded and how to Improve the Performance
NOTE: (If the performance of my tablet on the video on youtube is the same as the performance of stock rockchip rk3188 tablets/devices, please do say it to me so that I will be able to change some Description on all of my posts across the INTERNET!! Thank you!)
so.... here is the learning diary and test journal
CHAPTER 1. Full brick at 1st week
The x7010 did not had any kind of update OTA from skyworth, and was replaced quickly by x7011. Since skyworth is a chinese company, i am not really expecting anything from them. but the sad part for me was when i bought the tablet, (About $150 converted currency) and then looked over the internet for supports such as CWM Recovery, CROM, Cyanogenmod or anything else, I FOUND NONE! Great! Not even a Copy of STOCK ROM! Which give me the idea of studying/learning the developing since i had already interested in doing so, and will also make me one of the pioneer custom developer/cooker for our device.... YEY!!... but it was not easy, IT WAS A HARSH PATH....
After my 1st week of trying, I already got a FULL BRICK ON MY DEVICE, But lucky me, im a great actor, so it ended up replaced from the store since it was still covered in the 1week replace 1 year service warranty. (I had softbricked the device by trying to flash Finless rom 1st try, then glassrom 2nd try, then i fully bricked it by flashing with no bootloader & parameter, erase nand db so that the store wont find out that it had been rooted and flashed!)
Chapter 2: Unbricking Success!
So on my 2nd chance, First thing i did was to do a ROMDUMP for backup (NO CWM YET), then I tried to create another CWM Again BUT I FAILED, Where i left it as is with no recovery but working system.... then i posted my 1st post here and in freaktab WHERE I stated that I want to learn and dont want to be spoonfed... Then after a few days, leolas tried to make the CWM!!! but I cant seem to flash it via flash_image, so I used a 1.37 rk tool, to flash the recovery, (Now i know that i messed up the partition offset of the recovery before so it doesnt really boot to recovery!). but by testing out what i understand from the forums, researched alot regarding parameter, mtd partition, the way android system boots and operates, i finally flashed the CWM Successfully on my device! so i backed up trice the device, and since i was so excited, i tried to flash a new rom again, but the excitement and an old mouse that double/triple clicks BRICKED my device by flashing it with NO PARAMETER AND BOOTLOADER, and all other are checked and the flash are already being erased.
No more bootloader mode, no more adb, not detected in PC In any way. then i found out the pin 8& 9 shorting for the nandflash unbrick method, tried it, stripped down my tablet, but i was so sleepy so it resulted in a failure. I dreamed that i will be able to revive the device by retrying it so when i woke up, the first thing i did was to do the PIN SHORTING then i plugged the usb cord, then poof,! Success! MASK ROM MODE FOUND!! then flash my romdump (Backup from cwm with tar and tar.a cannot be flashed ). Although i have one problem, the dump have the system in .tar and i need a .img, so once again, GOOGLE! kept on searching till i stumbled on a forum where an instruction of how to make a System.img flashable from update.zip. Using a Linux mint VM then plus learning basic syntax of linux, got it working ! .
Chapter 3 - BRAVERY!
This scenario made me think that NOTHING CAN STOP ME NOW! since it was the most difficult part for me, especially the unbricking part. so ill make it a little bit short, i flashed many roms, and recorded the differences for every rom,(ALL ROM ARE FOR RK3188, m9, u8gt,mk908, t428, glassrom, m9, etc), some rom displays, some don't, some boots, some doesn't. I also learned to logcat, read logcats, read and debug using dmesg. the rom that had been most compatible for my device is the chuwi rom v88 by oma (Yeah it rocks!) with working wifi, bluetooth, and everything else except for 3 problems, Inverted Camera, Accelerometer not working and NO SOUND! NO AUDIO! WAAAAA but was able to use it still, and checked the performance. run some benchmarks, played some games, although no sound, it was fine, with a few random lagging.... still, i continued to study it and modifying.
Next part was the System UI - framework.res and baksmaling and modfying apks, mostly for the User interface, and those were pretty easy since you can use the TRIAL AND ERROR Technique!. I have already the idea for the configs in build.prop, and just did some trial and error. By doing all of this, continuously, i am learning different syntax & commands too using adb and terminal emulator. so in the end, i maximized the performance of the rom, without touching the kernel. But i still notices the lag, one scenario is this, Fresh boot, Playing NBA2k14, then by some reason, after the camera zoom, the game slows down or get a little lag, about 22 - 28 fps, in order to get back to the max fps gaming, sometime i touch the notification area, sometime pause - resume. and when i am on max fps on any game, then accidentally touched the home / recent button, when i return to the app, it gets so lag! and when playing simultaneous game, it gets really lag.
Start the tweaking
I know this symptom, Applying my knowledge & experience in desktops. I had declared to myself that THIS IS THE EFFECT OF A BOTTLENECK! (Unbalanced specs & performance) or Memory bus width too low therefore bandwidth limits the overall performance so i checked the OC of the device, then found out that it was not overclockable thru software.
Google is my friend, and found out that i need to compile my own kernel that enables the Clock adjustment of the device to exceed the 1.6ghz. I was too naive that I Underestimated RK3188's Power. my initial goal was to OC the CPU itself, but after googling hours and hours, asking my mentor on how to compile a kernel, looking for sources which was the same for our device, eventually i found none xD, then, I stumbled upon.... OVERCLOCKOMATIC / Patchomatic!! a linux app that enables patching kernel's clock settings. And i found out that it can patch ram / gpu / cpu!
Since i was An Experienced Overlclocker (Overclocking on desktop, e5400 (2.7ghz Raised to 3.15ghz), On AIR / STOCK FAN + Exhaust & intake circulation). First i did was a hand made heat spreader (To make this, you need an aluminum foil, fold it into three, with the width of about 1-1.5 inch, then cover most of it with any tape except for the part that will be connected to the target(my target is the cpu), and the other end for the receiver/outer/safe place to transfer heat.) first, my target is my procie and spread it through the sd card slot, and another one from the procie to the aluminum case on the wifi & bt (it was covered!) i moved the 1st end from the sdcard slot to the back cover later on when i realized that i might damage the sd card or the socket itself .
Then I tweaked it and tweaked it for days, checked stability, compared results.
our kernel is 3.0.36 compiled on ubuntu! Yey! at first i was running the device on 1.8ghz, then later on i reverted it back to 1.6ghz, due to heat issues that may damage the device with prolonged use and to save battery spantime too.
But not everything is about the clockspeed, especially when i checked the GPU CLOCK IS ALREADY MAXED, So what would be the cure or solution for the bottleneck....
of course, the logics of tweaking a processor or ram or gpu are the same for the desktop. SO HERE ARE THE MOST IMPORTANT THINGS THAT I LEARNED AND WILL SHARE FOR EVERYONE EVEN IF THEY ALREADY KNEW IT OR HAD IT ON THEIR DEVICE ALREADY OR DOESNT hAVE A CLUE!
Chapter 5: OVERCLOCKING? the correct term to it for me was clock correcting / clock tweaking.
This is the EXACT modification of the kernel clock and stepping on both cpu & gpu and ram on my kernel which IS INCLUDED IN MY CROM Where everyone in our country(philippines) with x7010 tried and was satisfied of the great improvement of performance. and last week, some russian had already visited our facebook group and was testing my rom already . they also shared some roms of their own, although i think they are ported too.

RAM
modifying the RAM (2g DDR3 sdram 1600mhz) to be run @800mhz like a ddr2 instead of the stock @400mhz like ddr1 thus increasing the bandwidth have a huge impact on MALI-400mp4 gpu since the Quad Core Rockchip Processor were fast enough to make up for the lost clock cycle but lacks bandwidth because of the 32 bit bus width. BEWARE! Our ram is 2gb ddr3-1600mhz, which have a normal voltage of 1.5v. Low profile sdram modules have only 1.2 / 1.3v normal running voltage. YOU WILL NEED TO MANUALLY CHECK THE SDRAM MODULES ON THE DEVICE ITSELF TO IDENTIFY What type of ram it is, is it a ddr3 sdram? ddr2? a low profile? and clock timings? Ive used google to fully identify my hynix ram specs and even tried running the RAM @ 800mhz 1.5v and no restarting / corruption issues! it just that it drains the battery really fast. for our device, the exact and sufficient Voltage for the ram to perform well @ 800mhz is around 1.3v - 1.35v although im using 1.3v only. THIS IS NOT APPLICABLE TO ALL RAM and WILL REQUIRE MOST OF THE ATTENTION, EFFORT AND TIME TO APPLY CORRECTLY AND SAFELY!
I cannot guarantee your life or you freedom !
Some Info on ram: Lower clock speed of ram have faster clock cycle (on default clocks of actual ram sticks) Higher Clock Speed of ram have slower clock cycle BUT Bigger Bandwidth.
Low Profile RAMS Uses less energy(VOLTAGE), expect a slight decrease in overall performance....
Some Rams have lower clock cycle and latency in their stock settings compared to other. This are the high profile / OC'ed version of rams..
Anonymous asked: "Why did you use ddr800 against ddr400 config for our ram?"
RK3188 is a quad core processor with 512kb (L2 cache per core i believe) running @ 1.6ghz which are ULTRA FAST and can be compared to an AMD athlon Mobile processor ! it was so fast that before that RAM Cycles to refresh, all the data have been stored in the ram had been processed already, so there was really no need for the quick cycle, PLUS The GPU Is an Onboard/SOC/bundled along with the CPU (like intel's I series and AMD A Series). Now They will need a Bigger bandwidth so the power of the cpu can be utilized more since more data (RAM IS 2gb, can store a lot of data! Really...) can be passed as the bandwidth is higher. therfore GPU have a wider data path for transferring the rendered graphics data to the cpu to process then pass back to the GPU or ram, dpending on situation, without clogging up the I/O Path.
Short Answer: Faster GPU and Read/Write speed at no cost (aside from a little energy drain for the increased voltage of ram, since the cpu can handle that load!)
Chapter 6: Cpu and GPU
CPU
Kernel patched, using rkpatchomatic / overclockomatic! (linux)
I also reduced the Clock stepping and adjust the voltage of the cpu from:
312mhz @ .9v
504mhz @ .925v
816mhz @ 1v
1008mhz @ 1.075v
1200mhz @ 1.150v
1416mhz @ 1.250v
1608mhz @ 1.350v (this may not be right, if i am not mistaken it was only 1.3v @ 1.6ghz on stock)
(6steppings)
to
504mhz @ 1v
1008mhz @ 1.115v
1416mhz @ 1.250v
1608mhz @ 1.350v
(4steppings)
AND the GPU speed increase by loading the driver module with:
insmod /system/lib/modules/mali.ko (removed mali_dvfs & mali_init_clock=133)
and also changing the GPU voltage and stepping FROM:
133mhz @ .975v
200mhz @ 1v
266mhz @ 1.025v
300mhz @ 1.050v
400mhz @ 1.100v
600mhz @ 1.250v
(6 Steppings)
To
200mhz @ 1.05v
400mhz @ 1.15v
533mhz @ 1.2v
600mhz @ 1.35v /1.3v
(4 steppings)
OR
266mhz @ 1.05v
400mhz @ 1.175v
600mhz @ 1.35v
(3 steppings)
The Steppings Reductions Resulted in a VERY VERY Fast Application Switching (Not using a multiwin rom, but able to run about 6-7 HD games with seemingly no lags on switching). BUT Additional battery power may be consumed because of higher idle values for each settings.
My theory, explanation, and strategy was.....
GPU & CPU Steppings logic are the same, while for the GPU the clock increases, so as their texture and pixel fillrate. But gpu power may not be nough @ 1.25v during heavy loads, that is why i've used the maximum allowed voltage for the gpu, and adjust most of the voltages so that the system will never be short on current especially when switching state.
Wanderer asked: "why did you reduced the steppings and what exactly is that?"
Stepping is the term I used for the clock settings / stop point, It came from intel, they use Speedstep and steppings. as you can see, Most of the time, when not playing hd games or not running so many many apps, The cpu (based on my new config) will either run fine at 500mhz, - 1ghz only. (large bandwidth maximizes the power of the quad core of rockchip). so it wont need to adjust itself to 1.4ghz unless it really needs it, and it will not revert back to 500mhz unless all apps and memory are cleared and closed. (Even if you press the recent apps, it will stay @ 1ghz and will not drop to 500mhz). When running a solo HD game, except for 2013 Q4 HD games like CoD & GTA SA, cpu will be fine @ 1ghz, when running other apps, like browser, music player, etc etc, it will be kept in memory, and the cpu will have to speed up itself so it will be stable @ 1.4ghz, when running multiple hd games, it will run @ max 1.6ghz.
The stepping settings helped the cpu to be STABLE @ certain clock during prolonged usage.
Plus, rk3188 is not a very good at clock switching / stepping adjustment. Some users of rk3188 uses a cpu tweaker and set their clock permanently to 1.6ghz right? but it consumes battery faster. I tried different numbers of steppings and clock config and this was the best result for performance. Well in reality, if you are going to overclock a desktop processor, you will disable the speedstep or clock switching feature because it consume power and energy. imagine that the processor needs to consistently monitor the cpu load and adjust it according to its needs. even a human will have a delay of a few seconds during the adjustment and calibration of the strength, the same logic applies to the processors too, plus if you will add the stress of the switching of the GPU, bugs and lags are generated, sometimes, it takes quite a while for the gpu to adjust its clock, from 133, to 200, then lags a little, adjust cpu, then gpu from 200 - 400, then suddenly you pressed the home button while playing, gpu reverts back to 133mhz which is far from the max, ew, where in my config, you start at 233, making everything seems to be so smooooooth, even if you enable AAx4 in the developer options you wouldnt notice the impact of it in performance, then you can disable hw overlay and enable gpu rendering too to maximize performance! if you want to save battery, then choose the 4 steppings on gpu, if you are a hardcore gamer on tablet, then use the 3 steppings on gpu, if you want more, replace the 400mhz config in the 3steppings with the 533 from the 4steppings.
STORAGE
I have Also increased the Speed if reading / writing in the nand flash by mounting mtd partitions with:
ro noatime nodiratime noauto_da_alloc data=writeback barrier=0 nobh
TIP {
instead of using an app to mount the android folder in external sd, you can use a terminal emulator, then this command to mount the folder from exterlan sd - internal, so you can play more games! (Note: please do create the /Android/data and /Android/obb on both internal and external SD
$ su mount -o bind /mnt/external_sd/Android /mnt/sdcard/Android
or
# mount -o bind /mnt/external_sd/Android /mnt/sdcard/Android
to remove the mount/bind
$su umount /mnt/sdcard/Android
or
# umount /mnt/sdcard/Android
The mount / bind is not permanent though, and you will need to enter the command every restart of the device.

two thumbs way up for you kabayan! I'm no coder, but I love to read and tweak usually consolidating tweaks/scripts for my myPhone Vortex.
Good thing its a fairly popular phone in India, else I would have been stuck with the stock rom.
I'm curious if your rom can be applied to the recently released tablet from Starmobile : Engage 8 quad+
It sports the same processor as your Skyworth but with 1G of RAM only, 8G internal. Been looking around and I've read through
the list of roms you've tried (PIPO, M9, GLASS) and its a good thing I found your thread. I would have risked to root and flash
my tablet with any of those roms.
I'm currently reading on rooting my tablet using this method below, however I'm now hesitant to proceed. Would you have another method that
would work? or at least give me a little more confidence of root success. Thereafter, its CWM, then flashing time! woot
http://www.slatedroid.com/topic/88850-rooting-rk3188-tablets/
btw, I've found the manufacturer of this tablet, guess Engage 8 is a rebrand of this unit.

Hello, I'm new on this forum then I'm sorry if i post in a bad section for my questions... But I think I should post here.
I've got several questions:
- Is there really no risk about undervolting CPU, I asked me about this because no one forum tell risk but compagny thaty produces phones don't set the minimal voltage required for each frequencies.
- Is there an app to force CPU usage at 100% to test undervolt options.
Example: I undervolt 2265MHz with -50mV, I launch app, click on 100% uage then it use at 100% my CPU, if it crash undervolt is to high. If it don't crash undervolt is good, maybe continue tu undervolt.
- Is there an automatic app to undervolt ?
Example: It decrease 1mV by 1mV with always the same frequencie of CPU and 100% CPU usage then when phone crash it restore the last value of voltage, then it do it with another frequency etc etc ...
- Which voltage do you use ? And are there voltages the same for all nexus 5 or they will change depending of each processor.
To give me an opinion about what to use
- If I found a minimum voltage, will it be the same for all kernel ?
Example: I'm on Kernel A, my min for 300MHz is 725mV, I switch to kernel B, Will it work with 725mV for 300MHz??
More generally it depend only of the processor or also of the kernel, governor, I/O scheduler ??
I Think it's all maybe other questions will come
I Thank you for all your constructive response. Don't hesitate to ask me to develop certain question and tell me mistakes .
Theres an undervolting thread. Should be linked in the "Sticky roll-up thread" which you can get to via my signature
Okay, thank you
Okay, I will copy/paste my message
Thak you for the information.

Frequently asked questions
Q: Will this conflict with any mod I'm using?
A: As long as it doesn't have any entropy related stuff, its okay. Since the kernel already comes with an inbuilt entropy generator, it will conflict with the ones from mod, causing a poor, stuttered performance!
Q: Deep Sleep isnt working for me, Google Services causing wake-locks, what to do?
A: Go to settings, Privacy, Privacy Guard, All apps, long press Google Services, and deny/disable wake-locks! (Thanks to @Paget96 for the solution)
Q: Is your kernel secure?
A: You MAY face some issues, but it's safe! My cell phone has not exploded yet.
Q: WiFi doesnt work for me.
A: Reflash ROM and Kernel.
Q: What application can I use to configure the kernel?
A: Use Spectrum, and if you have enough knowledge of what to modify or do in the application use together Kernel Adiutor.
Q: Can I use the kernel source in my ROM?
A: If you want to use my kernel in your ROM, just put my name in the credit, just like I did.
Q: Does your kernel support writing to the NTFS file system?
A: Yeeh, you can use flash drives and HD with NTFS via OTG.
Q: My cpu clock is locked with any governor.
A: Just disable the thermal control in the kernel temperature settings.
Q: I have problems with your kernel.
A: Take a logcat and kmesg, this website and this video should help you
Q: Why does my magisk and root disappear after installing your kernel?
A: The kernel script makes changes that directly interfere with both, reinstall the magisk that it will function normally, follow this installation line always: FloppyKernel -> Magisk -> Reboot system.
Q: What is the "Battery" profile in the spectrum?
A: Based on Project Zhana & X.A.N.A was made for trying to be as efficient as possible without compromising the performance. Thanks to the discovery on Voltages used by our SD820 I could make a profile that utilizes more the BIG cluster. My first attempt was to move ALL the load to the BIG cluster, it was against anything that I have learned about little. BIG CPU but I tried, it turned really good at first, low usage was just amazing... But on more usage things didn't go that good. So what I did it was to give a twist to things, but not such twist. It kind of works like Nameless and Shotgun, Mostafa Wael and I worked the same idea. #LITTLE cluster will be running on low-mid frequencies but delivers full performance when is needed. # BIG Cluster will help LITTLE ease Load, but in a great way than before. Things can be done faster and more efficient giving us profit in form of battery. It should run smooth on all scenarios, but you guys tell me. You can easily get around 7~9 hours SOT for 24 hours even more If you don't play game. This will, of course, may vary, but it will definitely be better.
Q: What is the "Balanced" profile in the spectrum?
A: Based on GhostPepper was made to uses a quantized, frequency-aligned parametric curve to influence low core clock rates while providing extremely smooth transitions from each clock rate and exceptional battery life. Really well-defined clock speed escalation for a good battery and performance.
Q: What is the "Performance" profile in the spectrum?
A: Based on FusionP this profile brings a more "agressive" way to scale frequencies. It will scale frequencies sooner(regarding load values from cpu) and will use more the big cluster to provide more performance doing the tasks on hands. Battery should not take a big hit but using heavy demanding tasks you can expect a higher drain.
Q: What is the "Gaming" profile in the spectrum?
A: Based on Burnout PR5, this profile's main goal is to provide absolute maximum performance when needed, but lies low quite well. You see, some times I see the CPU hitting some of the high freqs of 1190 while making something as simple as watching YouTube or playing some spotify tracks needlessly, and sometimes I feel it is a bit slower than it should be in things like brute multitasking. Most profiles do aim at bringing a mid-ground to rest on. But with the sensible words of one of my favourite idols Jeremy Clarkson, he says 'Power solves everything' and right he is. By eliminating the mid freqs of the Little cluster and efficiently using some specific frequency steps, you get some power savings by staying on lower freqs as much as possible, and even on brutal tasks you get the job done faster as well, since the CPU will give you all the power to finish the job as fast as it can, and hit back to idle faster.
Q: I want more information about your spectrum profiles.
A: Read this thread.
Hi there.
Is it possible to run this kernel on the LOS 15.1?
Did read that it is for the 14.1, but you know, why not try to brick it?
Have you tested it? Cause the android go version of oreo with a good kernel could really make thea a brand new entry-level phone. With google camera 5 it could even compete with some budget phones from 2017.
Thanks for the kernel, Just flashed it on AOKP Nougat and it's running smoothly.
I discovered Spectrum with your post, amazing app to don't have an headache with kernel tweaking.
However does Spectrum activates a hotplug or does I have to activate it with kernel adiutor or else ?
PS: Spectrum profile's values can't be seen in Kernel Adiutor, I just see Lineage profile values... Also by looking at your spectrum init script I see that you assume that Thea have BIG and small clusters. when I'm trying to `cat` the value for some lines they do not exist.
Thanks a lot for keeping our good old Thea alive.
One more thing.
Could you make the kernel compatible with the oneoplus camera from this post ?
What camera app are you using?

Yes, I got this script from the source of my Mi5, some lines do not change it, because the kernel moto g 2014 does not have the resources

Tried flashing your new build...dirty flashed and then, because it wasn't working, clean flashed on 28/12 and 29/12 build of LOS 15.1 with TWRP 3.2.1-0. But unfortunately the phone (thea - XT1072) was stuck on boot logo every time. I really would like to see the kernel working on LOS 15.1, because it worked really good on LOS 14.1.
A few questions mate:
So the cpu is clocked to 1.6 Ghz right? Cpu z shows it reaching 1.2 only. Perhaps on performance profile?
How do i enable dt2w?
Got some lags in some animations, for example in settings, going to display, the animation in between is kinda sluggish. Whats funny is, overall the device is smoother! Some settings must be changed perhaps?
Is the permissive Selinux a big deal?
Im using Los 14.1 with your balanced profile. Thanks, happy new year!

Use kernel adiutor, cpu z is not very good to get info, dt2w dont work on thea, only in titan, it is normal to have some lags, after all it is an old device already, it also depends on its use, selinux dont will stop the lags, if that's what you're thinking
I'm using in titan, your kernel doesn't lag but battery gets horny (bad joke) I mean that the battery duration got worst, you maybe consider undervolting a little and upgrading your lmk parameters because it does make apps don't lag but it's a little aggressive, it does FC my keyboard (google keyboard) and I don't wanna be annoying but I have a request, can you bake voltage control into the kernel?
---------- Post added at 09:39 PM ---------- Previous post was at 09:26 PM ----------
I can provide sources for voltage control if you want and, where I send logs?
---------- Post added at 10:21 PM ---------- Previous post was at 09:39 PM ----------
The fix for laggy animations when opening recents and for almost the animations is disabling the adreno idler, or tweaking it
If you have any other test builds for 8.1 just pm me so I can test it
I am using Thea. I like your kernel but had to remove it and restore a backup because the battery usage settings was hanging. When I unplugged after charging it still showed up as charging. That I could fix with a restart but then it wouldn't show what apps was used since last charge. Didn't note any significant improvement in battery duration the days I tried out your kernel.
BTW is there a way to remove your kernel without having to install a backup?
Are you still here?
Is this kernel compatible with Android 8.1? I am running LOS 15.1 but I want to use FloppyKernel because I loved it when I was running Nougat.
However, there is a problem. I can't afford to flash it because I am currently using my device a lot and there is no boot.img in your script. I tried to manually repack a boot image with your Zimage and hot-boot it from Fastboot but it stays stuck in the Motorola logo when I do it. I dumped LuK's Oreo kernel and it hot-boots fine. I'll also try to build your kernel from source.
I really hope that you didn't abandon this device too, but if you did then I will try to become a developer for this nice old phone.

Ehm... hello everyone
Our phone is quite a little powerful beast, but Xiaomi really made a crappy job on optimizing it, right?
After unlocking the bootloader I felt the need to go back to my roots and get my hands dirty to fix the wrongs in the kernel they released. The phone felt slow and heavy, the battery barely lasted a day. I use my phone for my job and I need to be snappy, stable and last way more than a day. So I started tweaking, digging and experimenting and the result is this kernel that I'm releasing today, in an attempt to make our MI9SE a bit better for all those people who actually use this phone... as a phone...
This kernel is GSI / AOSP only. Don't flash it on Miui based roms unless you are suicidal or want to lose some features, in which case you're free to do as you please and I'm free to ignore your posts, right?
There will be, from time to time, experimental/unstable versions that I release for public testing (usually they're not harmful, but... ehm.... ok you get it) so watch out for the second post if you feel brave and want to be on the bleeding edge. Official kernels are released when the beta testing phase is done and 100% of the feedback is positive.
Don't ask for ETA or you'll be fish slapped... badly! Ignore this warning only in case a nasty bug slips in the release, then you can fish slap me
Ok, enough talk, let's get down to business now.
Features
* Compiled in release mode (all debug stripped)
* Removed all auditing
* Disabled modules support to avoid interference from Xiaomi vendor
* Battery friendly, performance aware
* DT2W support. If disabled the display and touchscreen will power down

* Support for F2FS
* And loads more... yeah just ask or check my github
Q & A
Q: Battery !!! Why it's so baaaad ! My phone doesn't sleep !!!
A: Well, don't get it badly, it's not really my problem, is it ? 99.999% is an app you have installed that's preventing deep sleep... go ahead and install BetterBatteryStats, check the Partial Wakelocks and se what's killing your phone. Have fun
Q: App X crashes ! OMG all my data is gone !!!
A: Read again on top, not my fault, sorry. I try my best to give out a stable kernel, but "**** happens" and i can't control it...
Q: I get tons of bsods, my phone doesn't wake up from sleep, it freezes and omg... it just exploded !!!
A: No dmesg / logcat, no party. And please don't post messages like those in the thread if you're not ready to attach a log to the post.
Q: When will you enable gpu overclock, road runner speed mode or wile e. coyote immortality ?
A: Never... on a second thought... maybe... who knows ?
Q: When will you release the new version ? It's a week we're using the old one !!
A: Is it stable ? Then please allow me to fish slap you with a huge trout !
Downloads
All downloads for Kowalski Kernel will be linked in the second post AND in the thread when a new version is released and a changelog will be filed accordingly.
The downloads are labeled as "kowalski-XY-grus" where X can be either "r" for release or "b" for beta. Y is the version number. Eg: kowalski-r1.4-grus is a release, while kowalski-b4-grus is a beta version.
Source will be pushed to my github about 2 or 3 days after a release (or before if I'm not careful), to make sure that no major bugs are introduced in the public repository. You can find the magic code here
This kernel can be compiled with any clang 4.9.x that supports the aarch64-linux-gnu target, so if you want to compile it by yourself you'll have either to build your own toolchain, or use one of the many prebuilt ones (for example from aosp).
Please don't rip-off my work. Please don't kang this kernel. Please don't c&p from my github without proper credit. I'm a nice guy, but i will report you.
Little code of conduct for my threads is necessary: no drama, no OT. Oh and please don't message me on Telegram privately when we have this awesome platform where everyone can benefit from the Q&A.
Thanks
* Okita for the awesome job she made on the base kernel cleanup (this kernel is based on one of her first releases)
* Linus, well, for the linux kernel
* francescod for taking the risks of testing possibly harmful pre-releases
* qualcomm, because codeaurora is awesome!
* osm0sis, the one who allowed us mortals to provide flashable kernels without pain
Oh, I was almost forgetting... on a side note... i'm not really responsible if you decide to test it and your phone melts... right ?

* /sys/devices/platform/soc/soc:qcom,[email protected]/msm_fb_ea_elvss_off_treshold (the brightness threshold under which the system is enabled)
Wow, finally a full battery and features oriented kernel. Great to see it for our little beast. And with no Miui support
I hope you don't fall in modern famous useless stuff as Overclock/Overvolting Cpu-Gpu and Overclocking display. Grus doesn't need it at all, at least now.
I'd like to thank you of course, for all of your hard work done. It was a pleasure to help just a little with testing!
After many test of various configurations I've come to these stable settings useful only if you're searching for some more battery juice, so, no high demanding games at all! Performances on daily light use, seem to me like the same as with stock values.
Cpu Governor: Blu_Schedutil
Freq small cores: 576-1516MHz
Freq big cores: 300-1536MHz
wq_power_saving: enabled
Gpu Governor: Simple_ondemand
Freq: 180-267MHz
Adreno Idler: active (should work only on MsmAdreno Governor, but I like to see it enabled anyway)
I/O scheduler: Maple
Readahead 384kb
Fsync: disabled
Tcp congestion algorithm: bbr or westwood
To maximize even more the battery saving use black/dark grey apps as much as possible, use the right brightness, turn off any fancy features as AOD, FOD, AmbientDisplay, PocketMode, every unused sensors, install AdAway, Greenify, use 2G when in Wi-Fi or 2G/3G/4G on mobile connection and pray for someone :cyclops:
All of these settings are fine on my device with my personal use and my personal apps, so, don't complain about bad behavior on your phone.
Which what GSI are you using your kernel? I'm on PE but it will be snappy to have your same experience... :fingers-crossed:

Hey there, at the moment I'm on Floko because I need stability. Using it with latest xiaomi.eu vendor/firmware blobs and all is good so far
I know people using this on crDroid or Havok and no problems or issues are known so far.
Stupid question: What is different / advantage against Okita kernel?
I'm glad to see new and new kernels and ROMs for 9 SE. Thank you @pengus77
Does it work in miui rooms? Thanks

This is a fully debloated Kernel from Miui/useless/redundant stuff, so, for an only custom roms lover as me, it's perfect.
K-Lapse, Adreno Idler, unlocked frequencies and flickering reduction are the main visible points, with ofc more under the hood. I left OkitaKernel when it was perhaps on v4 build, so check it out what's changed recently on it.
While they're born from the same base, each Dev makes own customization, so it's up to you to try them both and choose the one who satisfies you better.
Finally I wanna thank again @okitavera for her dedication. Probably without her kernel I wouldn't have bought the 9 SE so fast :highfive:
@pengus77
I flashed your kernel ... is it working but after every restart I give this message: "Device has an internal problem. Contact the manufacturer for more information." Is it problém with firmware / vendor?

Hi, yeah, it's absolutely normal and harmless. It's a standard thing Android *****es about on GSIs when the kernel is too "stripped" and can't neither debug it nor load modules and/or there is a mismatch between system and vendor props. Search for that message in XDA and you'll see that tons of people have the same "issue". It's nothing to worry about, the system will work just fine.
Some ROMs are more strict than others. I know Floko says that, while Havok doesn't.
Roger that - I will be keep testing.

Kernel have in default min 576 MHz - is it so intentionally? Otika was 300 MHz if I'm not wrong. Doesn't this have a negative effect on higher consumption?

It's just the default to keep it a bit more responsive. Little technical explanation follows: When the phone is in suspend, the cores are disabled and the cpu goes in low power state, so the frequency doesn't really matter. When in active use, the energy and time required to reach a target frequency (when boosting on touch for example) is pretty high. Having a tiny higher min frequency actually lowers the power needed when a boost is required and the time to reach the target frequency is lower. When idling the energy consumption between 576 and 300 is basically the same and doesn't impact the battery life.
Of course the frequencies are unlocked, so you can set it back down to 300 if you feel more comfortable with it
Beta Release [ b1.5a ]
In the releases page on my github (and in the second post) I just pushed a little beta release.
Thanks @fereidooni for finding out a nasty bug occurring during hard memory copy operations .Will fix it soon, in the meantime ignore this version.
Changes:
* Adopted a drastically more power-efficient and reduced IOMMU implementation (your battery will say thank you)
* Cleaned up a few things (this will never end I think... sigh...)
* Disabled the MSM Performance min frequency override. Now YOU decide, not qualcomm.
Have fun

and beta build with GCC 13.0.1 klimbo is the first to relase with this gcc (you can find it in download at beta build folder)
*some compiler tweaks for more performance
*kernel renamed to KlimboBuzz
•GPU:
*OC UP TO 935MHz SUPER STABLE
*Optimized all GPU voltages. using only those that are most efficient at the temperature in general
*Adreno boost enable by default:
•CPU SCHEDULERS:
•Ondemand (default) tuned for more performance and less temperature
*fully removed schedutil (I think anyone using klimbo is looking for performance not a balanced kernel)
•CPU:
*Tuned cpu cores for more performance instead of battery savings
*A few more minimal optimizations that help sustain performance
*Change default thermal GOV to USER_SPACE (USER_SPACE Is a good thermal menager Because it reduces the throttling consequently benefiting for a considerable performance gain)
*Disable WQ Power efficient (WQ efficient is useless in a performance based kernel since when enabled It causes a loss of performance in Exchange for minimal battery
rest as in previous builds
Klimbokernel v5.0 features :
compiled with ZyC clang 16 (lasted)
-add and enable adreno boost
-added new I/O sched drivers like : ZEN, FIOPS, MAPLE, ANXIETY etc..
-more undervolt on GPU
-added and enabled new cpu governor : schedhorizon (the best for performance and battery)
-incrase armv8 timer 19.2MHz ~ 25.2Mhz
klimbokernel-v3.8.1 is up!
• re-added OC on gpu to 910MHz
• more optimizations in the audio driver.
• Several EAS commits for balancing power+efficiency
• Disabled Bootstats.
klimbokernel-v3.2 is up!
• FS and F2FS improvements.
• Reverted 250HZ base timer frequency (for more stability)
• Misc ARM performance and battery patches.
• Some I/O control tweaks.
..status for GSI : working
klimbokernel-v3-rc2 is up!
• Disabled Gentle Fair Sleepers
• Removed GPU OC - This is to test drive if performance takes a small hit but battery is gained. I have this as *temp change* consider it a 'test' phase so i will need your feedback on it to see whether if we keep it or not.
klimbokernel-v1.1-rc1 is up!
• reversed the cpu frequency table so the user can put the frequencies he wants.
• Implemented optimized PM QoS for UFS
• Built with cortex-a55 specific optimizations
• removed facebook process from 'kill-in-the-background' mod. This was affecting the user experience (for those that use Facebook a lot, like my wife lol)
• Disabled several not needed debug
• finetuned for SM8250 (Samsung) specific frequencies/values
• added: CIFS, NTFS and ISO9660 FS in-kernel Support
• Slimbus OC
• Several 'under the hood' improvements to task/memory management.
• set timer tick to 11000HZ this provides super low latency
klimbokernel-v1-rc2 is up!
•set timer tick to 9000 Hz for more performance..
• gpu overclock from 587MHz to 660MHz
• removed battery charging throtling

Very unstable but the speed is insane for me. The only version that work for me is the stable v1, without random resets. Great work.

in the latest versions there is no reboot, on telegram you can find
important message, DON'T WASTE YOUR TIME COMPLAINING ABOUT LOW SOTmy kernel was designed for stable performance as you can see in the changes abovethanks
.
Hello colleagues
does it work on one ui?
or only in GSI?

As soon as I entered the telegram group.
but i am seeing 2 variants
GCC and Clang.
what is the difference between one and the other?
thank you for your patience.

GCC is more optimized for battery, so the phone won't heat up as much, now Clang is more optimized for performance and the phone will heat up a little more but nothing crazy.
You're welcome.

I already approved the kernel.
currently try 3 different kernels(counting this one)
1.it allows me to modify and lower and raise the frequencies to my liking. no matter how you do it, the kernel respects it.
2.another kernel did not allow me to modify anything, I selected a frequency and it automatically modified itself. (I hate this kernel)
3.the kernel of this post.
is a combination of both:
I can modify only the maximum frequencies (I am not interested in moving the minimum ones, I have no problems with them)
I only have problems with the frequency of the GPU
It is activated at 932 mhz, it never goes above 490 mhz
no matter how much stress the team.
It is normal ?

About gpu
You should check if adreno boost is enabled by default, If yes, at which level, if at level 1 (Low) then this is the problem Because adreno boost locks Max frequency depending on its use and also the setting selected by the user
snapdragon teaks said:
Acerca de gpu
Debe verificar si adreno boost está habilitado de forma predeterminada. En caso afirmativo, en qué nivel, si está en el nivel 1 (bajo), entonces este es el problema. Porque adreno boost bloquea la frecuencia máxima según su uso y también la configuración seleccionada por el usuario.

Is rare.
send the screenshot.
I have to activate minimum frequency at 932 mhz.
I would like it to be scaled.
Try some bench apps like, 3dmark, Geekbench, Antutu, etc. Also Use the CPU float app you can find it in the playstore.. open CPU float and open bench apps start the test and check if the frequency goes up to 932MHz

use antutu.
the score was very low.
once I set the frequency to 932mhz as a minimum.
I was surprised.
