[KERNEL][I9195][Stock JB/KK] brisK v6 - Galaxy S 4 Mini Android Development

brisK Kernel​
brisK is a KitKat kernel for stock-based ROMs for the Samsung Galaxy S4 mini LTE (GT-I9195).
It aims to be faster and more a bit more battery-friendly than the stock kernel, while retaining its stability.
To prevent bloat I will only apply useful features like BLN. Adding 10 random governors and schedulers is not useful in my eyes, and is also not the goal of this kernel.
Goals
Stability: The original Samsung kernel is stable, so let's not go too far away from it. This kernel doesn't need bleeding edge code - it just works(TM).
Efficiency: Less power consumption by faster computation.
Battery: A battery drain patch is included, which is not in Samsungs original code.
Speed: Minor changes, for example: Trade some screen smoothness for less kernel overhead. Should not be noticeable, though. Also lowers power consumption slightly.

JellyBean Kernel
The old JellyBean kernel is no longer maintained, but it is stable and its uptime was above 2000 hours on my device. I published it here too, in case someone is happy with their JellyBean ROM and wants this.
Features: BLN, Battery drain patches, kernel config optimized, most debugging code deactivated

Installing
To flash any of these zip-files, you need to install a custom recovery on your phone. (For example: http://forum.xda-developers.com/showthread.php?t=2364980 )
Put zip file on your phone or on its microSD
Boot into recovery: Hold "Volume UP", "Home Button", and "Power Button" when it is off or rebooting
MAKE A FULL BACKUP BY USING THE BACKUP-MENU
Select "Install from zip" or something similar
Navigate to your zip file, select it, and flash it
Reboot your phone
Uninstalling
If you want to go back to Samsungs stock kernel or flash another kernel, you need to install "samsung_jb.zip" or "samsung_kk.zip" first.
brisK uses custom kernel modules. When you run on brisK and then directly install another custom kernel which has no custom modules, you will probably experience issues with WLAN and other stuff. To solve this, flash "samsung_jb.zip" or "samsung_kk.zip" (which flashes the stock modules), and THEN flash whatever custom kernel you want. - Of course you do NOT need to do this if you update to a newer version of brisK.

thank !
GREAT !!!
but for governors and schedulers , i agree with you in half ... but "few" of them are very useful !
what do you think about the recent "zen" ...or "row" ( by default in all customs like cyanogenmod ) ?
for you ,what are the "best" (more adapted ) for better compromise in performance/baterry save ?
why you don't add just 1 or 2 among the best of ones ?

Now running on brisK

I agree that some governors might actually improve performance, but there isn't much information available, some people say governor A is better, some say B is best...
But also: Kernel goal nr. 1 is stability, and ondemand is well tested. That's why I probably won't add any new governor before testing them a lot.
Can you suggest any governors? And do you have proof or URLs why they are better? Thanks!
If you want more features, more governors, etc, f4k will probably release a stock kernel soon. So keep an eye out for that!

Zen: I don't know what this does different than other schedulers, I have to read about this first.
I considered "row" when I had an Evo 3D, but I didn't notice a difference between "noop" and "row" in normal daily usage, so I'm not sure yet if I will include it or not - needs more testing.

Same thinking as me ...
ondemand for CPU Gov / No-op for I/O sched , they work great and don`t cause problems

Yes, my experience too!
Although, when I copy big files with "noop", android freezes for the duration of the copy process. That's the nature of "noop", but "row" might actually fix that. But then again: I rarely need to copy big files, so "noop" is okay for now.

No problems, everything works well.

Please add support for USB Host with additional power supply, is very necessary !!!!

NOOP hangs in general when the read/write task becomes too intensive. Consider CFQ if you're going to do a bit write operation, else ROW is better. That my two cent when I tried on my S3 with Boffela kernel.
PS. ZEN hangs even worse than NOOP.

I second that

thank for your work...
is your kernel working with old knox-free bootloaders like Silviumik's kernel?
thanks

battery life compared with carbon 4.4.4 ? PLEASE

For now i think no, because he did not remove Knox reference from source, i could be wrong tho !

I just released a new version!
A lot people asked for OTG, so here you go! I added OTG and BLN (untested!!!), thanks to junkyDE!
The highest kernel goal is stability, but I don't have time to test these features right now - maybe I can do one quick emergency fix tomorrow if something breaks, but after that I will probably not respond for 2 weeks or more.
So, have fun and enjoy!
brisK v2
Added OTG support (UNTESTED)
Removed TIMA
Change to XZ compression
Add BLN support (UNTESTED)

I removed TIMA in brisK v2, so.... it -should- work now right?
If it doesn't boot, just restore your boot partition from a backup or re-flash your previous kernel if you had any.

Thanks a lot for your input! Now I know I don't need to consider ZEN, and will stay with NOOP, and aim for ROW when I have time to add it.

FAQs
+ Q: Whats the difference?
A: Read the disclaimer.
+ Q: Will I get worse performance than the Official CyanogenMod Kernel?
A: It depends on what commits are added. My Kernel only fixes bugs i can fix and which are unsolved and Of course, I will add more features not available in CyanogenMod Official
+ Q: What makes the stock kernel different?
A: You get goodies, and furthermore, better battery life and performance in this project.
Nice to see a singaporean are so gd in it. Gd job Bro
Is it compatible with unlocked new boot loader?

Well, I don´t know where the 'bug' is coming from, but since the new CM10, notification light isn't working anymore. I'm no kernel developer but I think the issue is there anywhere.
It would just be nice if you maybe could have a look there, as it's a feature, I miss for more then a month now.
With the kernel on the new bootloader my Wifi doesn' t work -.-
Gesendet von meinem LGP990 mit CM10.
Please Read the 2nd OP before posting bugs here.
And, updated OP for WIFI Fix.
Take note, the fix is only for those who get those issues. DON'T Flash unless you get the problem.
Now, If you let me peacefully add more features
Saving up for an O2X!
EDIT
Updated OP for final Nightly.
Next version is the GM. Its the final version before release channel, which will be uploaded to ROM Manager's database.
hi there nicholas, i was just wondering, since this kernel looks very promissing, is there any chance of merging voodoo sound support in the future?

[KERNEL][G800H/HQ] TW & CM TardisKernel 1.5 ULTIMATE edition cpu/gpu OC and tweaks

got a nice new update for the snapdragon variants of the S5 Mini (g800h/ds/hq etc) and this kernel is as far as im aware quite unique across any device using the msm822x cpu. so you are all going to be part of a very special group for trying this one, that group is going to be the serious overclock group, this kernel overclocks not to 1.6ghz, not to 1.7 ghz but all the way to 1.8 ghz currently, and unless someone can let me know otherwise this is the fastest speed i have seen from a msm8226/8 based device. even the 2nd generation moto g only has a 1.6ghz clock.
changelog overall for this kernel from stock is :
Code:
Boosted Notification LED Brightness as default is quite dim apprently
Added UKSM(Ultra-Kernel Samepage merging) for performance and memory management
added interactive cpu governor
Enabled Fading LED Notification Light
Removed pretty much all debugging junk from kernel as its not needed
switched to linaro 4.9.4 compile with cortex a7 optimization
[strong]1.8Ghz CPU Overclock[strong]
550mhz GPU Overclock
100mhz Base GPU Clock (battery saving FTW)
zzmoove CPU governor
Few different I/O governors including FIOPS and BFQ
SU supported and have disabled samsungs stupid rooting protection
thanks again to sasukesama for testing this one, and again risking his device for it.
check the downloads tab for the files, i have created an update zip aswell as the standard img file and replacement wlan.ko for those who want to do them manually, i HAVE NOT created an odin file for this.
please remember to backup before flashing and i can not promise it will work on your device due to the silicon lottery when it comes to cpus etc.
any questions please feel free to ask
THIS WILL WORK ON TOUCHWIZ 5.1.1 ONLY AT THE MOMENT

i've edited it before flashing, but didn't deleted them..
i tried to use them but it didn't work, what did you use? can you send a link? i have a audiotechnica cks-77x, need to use it with full potential
so ill assume people are having success with this update

Hello!
I want to introduce my first custom kernel for the ZTE Axon 7. This is based of several sources, I cherry-picked commits to make improvements to the stock LOS kernel. I'm not a developer, but i really like to port stuff over .
We'll have two kernels one based off LOS sources and will try to have updated with each and every commit that is submitted and the other one will be Stock ZTE sources based. If you want to request for specific features, let me know and i'll do my best to bring them over.
Special Features:
BLX (Battery Longevity eXtender) added, check Post#2 for instructions.
Updated to lastest LOS Stock Kernel
Added a few governors like: lionfish / despair / darkness / blu_active / wheatley / ironactive and bioshock
added a few IO Schedulers: Tripndroid / Zen / SioPlus / VR
Kcal Color Control driver
USB Fast Charge
SafetyNet Patch (Bypass bootloader unlocked check)
Dynamic Fsync control
a little Overclock
Motorola Quickwake
Extended battery charge time from 30s to 100s
and manny other small fixes (you can check the commits in the sources)
Download

How to Bypass SafetyNet bootloader and/or root checks
* If comming from a clean flash of ROM or GAPS only do the following:
Magisk Approach
Flash the UnSu file from HERE
Flash my latest Kernel
Flash the latest Magisk from this thread:
Donwload Magisk Manager from the Playstore
Enable Magisk Hide in Magisk Manager
Profit, SafetyNet Checks will pass, all green!
SuperSU Approach
Flash the UnSu file from HERE
Flash my latest Kernel
Flash the latest SuperSU from this thread:
Donwload RootSwitch APP from HERE
Unpack the zip and install the apk inside it
Open Root Switch and disable root
Profit! SafetyNet checks will all be green!
Battery Life Extender (BLX) feature
In order to configure the cap you'll have to navigate to:
Code:
/sys/class/misc/batterylifeextender/charging_cap_level
edit the file and put the cap you want the battery to charge to, i won't recommend setting a cap lower than 90% cause then the phone could abruptely stop a fast charging cycle and damage your battery. If you want to have your phone charging to 100% just put 100 in the file and close it. No need to reboot, just plug and unplug your charger.
On a side note, this value will be set at 97% after every boot. So you'll need to manually change it back to 100.

AX7Kernel Changelogs:
AX7Kernel R9 - 03/22/2017
Updated Source with ZTE Changes in B19 source code.
AX7Kernel R8 - 03/17/2017
Fixed NFC issue with B19 builds.
Updated WLAN driver to LA.UM.5.5.r1-03800-8x96.0 github from CAF
Fixed the SDCard error shown in R8 version from 03.16
AX7Kernel R8 - 03/16/2017
Updated to newest B15 Source dropped by ZTE a few days ago. This is mainly a Maintenance Update. Keep in mind the Kernel works with 7.1.1 but it breaks NFC, will be fixes most likely until a new sources is dropped by ZTE.
AX7Kernel R7 - 03/16/2017
For both STOCK and LOS Based versions. Upstream Linux Kernel to 3.18.45 thanks to jcadduono patches.
AX7Kernel R6 - 03/03/2017
Cap for battery charging set back to 100% by deffault. BLX Settings, you want to change them, refer to this POST and to this POST. If you want to extend your battery's life think about adding the cap to a 95 or 97%
Fixed the issue where the phone won't go into deep sleep at all.
WQ_POWER_EFFICIENT MODE is enabled by default now.
AX7Kernel R5 - 03/01/2017
Cap for battery charging set to 97% by deffault. BLX Settings, you want to change them, refer to this POST and to this POST. Your battery won't charge beyond 97%.
Added options to manipulate thermal settings, now you can choose when the phone will throtle the CPU or when to start shutting down cores to prevent damage. My recommendation don't push it too high or your phone might get damaged due to the high temps. It's not set to 60 Celcius so i recommend lowering that to avoid damage.
Added WQ_POWER_EFFICIENT MODE ( you'll need EX Kernel manager to get this, it's paid app but it's totally worth it guys)
Enabled the option to 'disable' some wakelocks. Disable them on your own risk. Wakelocks that can be disabled are: Bluedroid, wlan_rx, wlan_ctrl, wlan, IPA_WS, wlan_extscan_wl_ws, qcom_rx_wakelock_ws - You'll also need EX Kernel manager to get this options.
AX7Kernel R4 - 02/24/2017
Renamed both the Folder and Kernel zip file to appoint to the version. Now we'll have 2 versions, LOS and Stock AX7Kernel, make sure to check the zip name correctly to avoid issues when cross flashing kernels. All LOS/RR/AOKP and other LOS Based kernels will have the word LOS in it.
Fixed BLX feature. It should now properly stop the charging process when the battery has reached the cap_level set by users. Charge will resume once the charge drops from the cap assigned.
AX7Kernel R3 - 02/21/2017
Added one more step of OC (pushed just a little bit further)
Added my own and really simple implementation of BLX (battery life extender) based on the work made by bedalus for the OP3 and OP3T
AX7Kernel R2.3 - 02/17/2017
Updated to latest LOS Stock Kernel
Disabled some debugging
fixes to ZEN ioScheduler - highly recommended now.
Disabled color inversion in Kcal - can't be used anyways.
Fixed USB Fast Charge - Should worl properly now.
GPU OverClock - 684MHZ max frequency now.
Adreno Boost added and enabled (should boost GPU a bit)
Updates to interactive governor (should work better when operation are in the background and screen is off - music streaming is an example.
Changes to the Sync
Changes to Random function for IO ops.
Updates to Zram.
AX7Kernel R1 - 02/13/2017:
Updated to latest LOS Stock Kernel
Added a few governors like: lionfish / despair / darkness / blu_active / wheatley / ironactive and bioshock
added a few IO Schedulers: Tripndroid / Zen / SioPlus / VR
Kcal Color Control driver
USB Fast Charge
SafetyNet Patch (Bypass bootloader unlocked check)
Dynamic Fsync control
a little Overclock
Motorola Quickwake
Extended battery charge time from 30s to 100s
Link will still redirect to R7 , androidfilehost is conducting a server maintenance. Once completed I'll upload R8 to the usual file location!
EDIT: STOCK R8 has been uploaded. Again, keep in mind this release is not fully compatible with 7.1.1 it breaks NFC, until we get an updated source it will remain as is.
Happy Flashing!

Yeah i'm sorry, i had to take it down. Forgot to add the exfat module and that breaks SDCard support. Will work on this tomorrow morning and will reupload then. For now R7 is there
So this is a kernel for the stock firmware?? I have b19 unfortunately so I can't test, 1 thing I surely want you to add on the b19 version if you make one, aside from all these cool features is f2fs support please make it happen.

Dang it >_> then freeza is my only solution for now
In case if you're interested about why I'm asking for f2fs, I am doing so to dualboot my stock b19 using @sbr method , unfortunately stock is ext4 and secondary can't be f2fs because it takes part in data, both either have to be f2fs or ext4
it's a bit complicated >_>

Why is f2fs so important to people. Back in the day, yes, it was an improvement in speed. Now, with today's storage speeds, it's performance is negligible yet people still demand for it. Doesn't it just complaints things now?

Exactly what I was thinking too.
Feeling the same. It won't hurt to have support tough. I'll try to add it but I'm afraid it could break the anykernel aprox ah since the support needs to be added Ramdisk wise and for that I'll need to move away from the current kernel approach.
I'll take a look at the lazy flasher scripts from jcadduono to check if I can patch whatever Ramdisk user has
Finished the R8 build... It was a PITA to fix find the fix for SDCARD issue (it was kinda silly what was breaking it lol). Also updated WLAN driver to CAF LA.UM.5.5.r1-03800-8x96.0 version published yesterday and fixed the damn NFC in 7.1.1 builds (this most likely break NFC in 7.0 builds). I'm sorry if you are still in 7.0 and need NFC, move on! ..
I'll push the update once android file host is out of maintenance (around 30 mins from now).
As to F2FS i have enabled the driver in the kernel and stock ramdisk supports data as F2FS so i'm assuming it should work. Although i don't use so if it doesn't i won't fix it
EDIT: LINK IS UP!
I'm not sure if I'm just blind, but I cannot find the link anywhere
EDIT: The file is there, found it in AFH over LOS version's thread. It's here: link removed

Download the bootstack of the firmware you have and flash it.

So does the stock version suffer from video playback issue like freeza's kernal?

Recompiled & Optimized Werewolf Kernel [SM-T211]

Hi!
I was looking through @laufersteppenwolf's kernel source and noticed it was compiled with -Os flag and an old toolchain. I decided to recompile it with graphite and -Ofast flags (the highest optimization level) and with a newer toolchain. Though the later failed (All builds with 4.9+ toolchains failed to boot on this device ) it still feels faster than the original build. I have also disabled some debugging options so that the kernel would fit in the boot partition in addition to some performance gain.
Features
Compiled with graphite and -Ofast flags (linaro 4.7.4)
Undervolted Wi-Fi, Vibration, LCD and Touch by 10% (Not sure if they're effective or not)
Disabled some debugging options
Added a lower charging current level (1700mA) to fast charge options (To reduce heating during charge but must be selected by user, Default is 1800)

Hey guys
As you already might have read in either the CM11 dev thread or the Q&A section, I am working on a custom kernel for our T210(R) and T211. It's still in a pretty early stage, but the current build is fully stable, so I thought why not share it
As I'm pretty new to this community, a few words about myself: My (only) device I have been working on is the LG Optimus 4x HD, for which I also made a custom kernel (also named werewolf kernel, who would have thought of that ). Me and 2 other fellow RDs were able to "switch" many blobs with the ones from grouper, which fixed many, many issues we were facing in 4.4 with the stock 4.1 blobs. I am the official maintainer of namelessROM and vanir for the 4x HD, and am also compiling GummyROM, LegoROM, unofficial CM 11 (using grouper blobs) and SlimKat for the 4x HD on a nightly base. And as soon as we have a proper device tree for our tab, I'm sure I can port the Tab3 to all those ROMs
Now, enough chit chatting, let's talk about the kernel
It's based on @ketut.kumajaya's blackhawk kernel (thanks again, mate ) From v004 on we are based on official KitKat sources, with some additions such as:
Features:
Various network tweaks
Entropy tweaks
I/O speed improvements
cortex a9 and neon omtimizations
Added frandom
Tweaked vm dirty ratios
Dynamic read-ahead values
Added I/O schedulers: ROW, SIO, BFQ, FIOPS, V(R)
Optimized AES and SHA1 routines
Added CPU governors: Lionheart, Adaptive, Intellidemand, Hotplug, Hyper
Reduced RAM usage from logger
Updated lowmemkiller
Overclocked to 1.420 GHz by default
Disabled vsync for better 2D performance
Overclocked GPU up to 624MHz (default 416MHz)
Custom user voltage control (CPU)
Undervolted by default (-25mV)
S2W and DT2W (WIP)
Fast Charging
KSM
Bugs:
You tell me!
Installation:
Download the kernel from HERE
Reboot into recovery (recommended to make a nandroid)
Flash the kernel zip
Recommended to wipe /cache
Reboot and enjoy!
And remember to remove phservice if you want to change some CPU/GPU settings yourself
Notes:
See 2nd post

Tweaking Guide
laufersteppenwolf said:
Since v002, we have an updated lowmemorykiller. It behaves a bit snappier than the old one, also with the default minfree values. However, in case you like to tweak your device a bit to make it even more snappy (like me ), I tweaked the minfree values a bit to slightly increase the free RAM without really affecting the multitasking experience. The script can be found in the attachment. All you need to do is to extract the script and place it in your /system/etc/init.d/ folder and that's it. The values will be automatically set on boot.
UV interface
The min possible voltage is 1000mV for now, and the max one is 1400mV. If you want me to lower the min voltage, please let me know.
Also, please note, that the voltage has to be changed in 12.5mV steps. If you apply for example 1110mV, it will be rounded down to 1100mV.
Fast Charge interface
The main interface is inside /sys/kernel/fast_charge/*
/sys/kernel/fast_charge/force_fast_charge (rw)
0 - disabled (default)
1 - use custom mA configured through the sysfs interface (see below)
/sys/kernel/fast_charge/ac_charge_level (rw)
rate at which to charge when on AC (1.8A to 2.3A)
/sys/kernel/fast_charge/usb_charge_level (rw)
rate at which to charge when on USB (0.5A to 1.0A)
/sys/kernel/fast_charge/failsafe (rw)
0 - disabled - allow anything up to 2.3A to be used as AC / USB custom current (USE WITH CAUTION!)
1 - enabled - behaviour as described above (default)
/sys/kernel/fast_charge/version (ro)
display fast charge version information
New kmsg layout
From v008 onwards the kmsg looks a tiny bit different. Instead of displaying the time since boot, it logs the actual time and date.
Now, you may ask yourself: "does that any good?" Sure it does. When you encounter an issue and grab a log, you can send it my way saying "the issue happened at 15:35". It is way harder to find out the exact time (in seconds) since the device booted, right?

It's on github but I didn't link to it cause it's messy. BTW There is no source code change aside from makefile and defconfig.
BTW, that link is blocked in India, can you upload it somewhere else? and also, cna you provide link to your source?

Sorry for late reply, I'm busy with my thesis these days. I've attached the file to the post. Will send you a link to the source (GitHub) in your PV.
Great! Finally something new for T211/0. Love to see some movement here.
Tried installing on a T210 with TRWP but get an error message. Anyone any ideas?
Tried to attach the error but it won't let me... Error talks about asset failed getprop ro.product.device == lt023g etc
@Samw13
SM-T210 = lt02 wifi Tab
SM- T211 = lt02_3g Tab
So, i have deleted requirement in update-script file and kernel seems to work correctly on t210.
Here's link to edited kernel: https://www.upload.ee/files/10238882/kernel-SM-T210-werewolf-Ofast-UV.zip.html

Is it fully stable on SM-T211??. Is it the final version??
Hi,
@mat1371,
@lol28
Thank you for the kernel for T210R. Stable, overclocked to 1.42Ghz. I have an issue with the settings I make, they don't stick after reboot. I used kernel adiutor, EX kernel manager, Performance tweaker. I have busybox installed.
I've flashed Powerdaemon.disable.zip from Gr8nole, still the same.
Edit:
I've found Gr8nole's suggestion about deleting /system/bin/phservice. I deleted the file, rebooted, changed to governor to lionheart. It seemed to keep the settings.
Thanks!

Systemless installer (doesn't touch system partition, OTA friendly), AnyKernel3 backend (compatible with autoflash apps)
Removed some debug and logging options
ARM enhanced performance and battery patches
CVE security patches, general upstream and CAF fixes for important subsystems
Modded schedutil governor merged from latest CAF sm8250 patchset
No OC, use 250HZ base timer frequency
msm_performance touchboost toggle on/off (enabled by default), tweaked cpu_boost driver
Enhanced TCP methods (westwood is default, BBR available), Network tweaks and updated drivers
Several I/O control tweaks, added schedulers ZEN v2 is default, advanced filesystems enabled (F2FS, ExFAT, NTFS, CIFS & NFS)
ZRAM Swap (LZ4 default) and with file disabled, LZO-RLE and ZSTD are available
Vibrator Strength tunable and Gesture Haptic Feedback control (touchpanel and FPR)
KGSL fixes and general improvements for GPU driver
adrenoboost ready (disabled by default)
Backlight min brightness and backlight scale option

FS fsync toggle on/off
Wakelock blockers available
wireguard support
CDROM emulation on mass_storage (compatible with DriveDroid 0.10.36+)

DOWNLOAD KERNEL ZIP
FKM download configs: oos | custom
(No mirrors please)​
Setup and troubleshoot: To install just flash the zip on a stock setup with either TWRP or autoflash kernel app.
If you come from other kernel or have any issues, you should restore your stock boot.img or dirty flash your ROM before flashing blu_spark zip to avoid problems. Also uninstall or clean data of any kernel control app you're using.
If you are upgrading between blu_spark versions, just flash the kernel zip.
About bugs and reports: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. I only active support stock OOS ROM with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with added modules, etc.
If you're using custom ROMs (including stock based ones) and OOS Open Betas you're much on your own. I'm mostly interested on debugging stuff in stock and stable OOS.
Also try not to spam the thread with OT. There's threads for all kind of stuff, use them.
Going back to stock: This kernel installer doesn't change your filesystem. You can backup your boot.img with TWRP or kernel app before flashing blu_spark if you want to go back to full stock or just dirty flash your full ROM.

blu_spark r12 release
All right crew!
It's that time again, 1st build is up :highfive:
This kernel source is unified for OP8/Pro, don't know how it will run in the regular model (can only test in the Pro). Let me know.
At the moment we're maybe at 80% of the usual goodies, get a nice and stable base and go from there.
I'm building with clang currently got some hiccups with gcc. I'll probably revisit this in the future but it will need more TLC.
You can now use FKM download kernel feature, just import the links bellow in the app :highfive:
blu_spark_r12release
FKM download configs: oos | custom
Build with latest Google Clang version 11.0.2 (Android 11) - blu_gcc may come in the future, needs som TLC
Synchronize codes for OnePlus 8 Oxygen OS 10.5.9.IN21AA and OnePlus 8 Pro Oxygen OS 10.5.10.IN11AA
Build errors and warnings fixes
Compiling improving and target optimizations
Goodies: IO and filesystem stuff, priorities and UX, touchboost, zram, wakelock blocker, haptic and gestures level, adrenoboost, etc
wireguard updates (v1.0.20200611)
init adjust for sdm8250
AnyKernel3 latest updates
For root, stable Magisk 20.4 or newer is mandatory

Also don't go spam and bug reporting on ROM threads if using this.

ur kernel is great for daily use when I have 6t, it's fast, smoot, and stable. do u plan to build one for oneplus 8?
Great to see your blu-spark here! Kudos
Great job! Any list of the best settings to activate for your kernel in FKM? Can't manage to activate westwood TCP method, it gets stuck to reno, for example. Or any config file to have the best settings selected, maybe? Sorry, I'm not too familiar with FKM yet.
Hey there, welcome. Nice to see you here.
Just one question, why are so many features listed in the OP and many or most not in the sources on GitHub? Isn't this a copy paste error?

I already inject settings I see importanton the background. TCP method is westwood by default, that reno situation is a bug from the app, franco is on it :good:

it's not working on regular 8
After installing this kernel I'm getting an option to boost GPU clock to 900 MHz. This also resulted in a much higher compute score. Is this normal? @eng.stk
On8 not working
Cool to see another old kernel dev from the nexus 5 days xD

Hum too bad. Seems like there's driver differences between the models, we'll see what can be done ib the future.
For now I'll concentrate on the pro.

You probably still have custom dtb from the kernel that have gpu oc, since this kernel doesn't replace the dtb and you switched kernels without keeping that in mind you ended up with mixed kernel images and dtbs.

So, how is that much GPU OC possible? that's almost double the stock max frequency!
EDIT: You were right, it was from "Evira Kernel". Now my question is, is that much OC safe? That's insane.
Do note that my device didn't get hot when I was running the benchmark even at 900 MHz.

At the bootloader unlock screen, after a few seconds, the text turns green and has black lines through it, when it finishes booting, by the screen goes completely black. Vibration and sound still work though. Have to force power off and back to TWRP to restore stock boot.
