For Devs that are interested in porting EAS:
Hey guys! We took all the EAS commits that make up RenderZenith and pulled them into their own repo. This will allow those interested to port our EAS work into their own projects! Note that you may have to adjust the Energy Model commit to fit your project.

EAS RZ-3.0.0 for OxygenOS release!
Sorry it took quite a while. I had EAS up and running since 20 Dec, but had inspiration for other performance improvements, and real life was happening for @RenderBroken and me. The wait is now over!
Instructions (IMPORTANT!)
- Dirty flash OOS before coming from another kernel
- Dirty flash OOS before switching to another kernel
What's in?
- EAS for msm-4.4
- Westwood TCP congestion algorithm (default)
- CFQ (default)
- Schedutil (default)
- Compatible with stock CAF performance framework
- WALT load tracking (default)
- Upstreamed to Linux 4.4.114
- Upstreamed to CAF 6.4.6100
- Dynamic Stune Boost v3 (proper top-app detection)
- Minimum freq set to 300MHz on Little and Big. We're currently evaluating the impact of CAF's new higher default min freqs.
- Compiled with GCC 6.4
FAQs
1. Is it...?
Yes, it's unified. All new OOS kernels are unified by default.
2. Notification delays over wifi?
I believe I have fixed it. Please confirm with me if you still face issues with this.
3. What ROM does this work on?
OOS Oreo only for now. I test my kernels on the latest stable release.
4. What about the missing features that were present in Nougat kernel?
We'll bring these features back in future releases.
Bug reporting
As always, proper bug reporting etiquette includes the following:
1. Logs (dmesg / ramoops). You may use Syslog app to collect.
2. A description of the problem and how to reproduce it (if possible)
3. Confirm that you have tried dirty flashing OOS followed by RenderZenith kernel again, and that you still experience the bug.
Let us know how the kernel works for you!

Awesome! Flashing as we speak. Thank you for this!!

Wow so glad to see this pop up........ downloading & flashing now

Great dev - great kernel. I'm glad you're here in the OP5T community :good:

Cool, new kernel for dumpling. Thanks for that..is it optimized for performance or battery? Comparing to stock oos kernel ,thanks

I consider myself a heavy power user. I get about 6 hours SoT being unplugged for 14 hours with about 20% left in the tank. I use BT and WIFI all the time, listen to music/audiobooks. I also think that our build is much smoother than stock. I am really happy with it.

@joshuous does this mean we will see vertexos on our device soon?
@RenderBroken welcome and thanks for your hard work. Will be flashing this ASAP!
Also, I realize this is a wip and your first release but would sound controls be something your working on? OnePlus, to comply with European regulations dumped volume of speaker and headphone volume way down with Oreo. Now I can barely hear what I'm watching while running. I know there are other possible solutions that could fix this but I'm not looking to flash any other mods unless necessary. Thanks, guys.

[Kernel 3.18.122][Android 8.1.0] Lambda Kernel for the Le Max 2 [Weekly][09/15]

Lambda Kernel was my development start point in the LG G2 glorious period, now you're looking at a new "horizon of possibility" for the LeEco device family. This Kernel has been written from scratch since January 2017, resulting in a small, polished and minimal core that's migratable across Kernel revisions.
It follows the flash n' go principle, everything packed in the Kernel is already tweaked and ready to be used as a daily driver for everyone.
The downloads, contributors and source code are at the bottom of this post, it is recommended to read everything before flashing.
DEVEL: My own testing builds for certain features and tests. They aren't normally shared, although sometimes I publish them. If you see one of them, don't forget they are recommended for advanced users/developers only because of their potential changes that must be debugged before publishing a WEEKLY version.
WEEKLY: They are closer to the proper release version but still can have some errors or bugs to be reported and tested, they should be generally stable.
SNAPSHOT: That's the version for the ones that don't want their devices to be lab rats for new features and staging changes. I don't know whether or not to say something is stable enough to be a SNAPSHOT but if you see one it's because it's been sometime running well.
Pretty straightforward once you get used to it, isn't it?
A general panorama for Lambda Kernel, always matching the latest release, in this case the WEEKLY from 09-15-2018.
HOT ↠ Source-code changes for Lambda Kernel.
COLD ↠ Environment changes for Lambda Kernel.
Latest Kernel Common 3.18 from Google's upstream HOT
Latest LA.UM.6.5.r1-09300-8x96.0 Kernel source base from CAF's upstream HOT
Latest LA.UM.6.5.r1-09300-8x96.0 Wi-Fi driver from CAF's upstream HOT
Compiled with Clang 7.0 and assembled with GCC 7.2 HOT

Read this twice before flashing/posting!
Cod. 000:
State: Placebo!
Priority: Urgent.
Overview: The thread is under construction here as well.
Read this twice before flashing/posting!
Q. How to install this Kernel?
A. Download the version you'd like to use and flash using a custom recovery like TWRP.
Q. What ROMs does this Kernel support?
A. It should support all versions of Android 8.1, being it CAF based.
Q. Does this Kernel support Treble ROMs or GSIs?
A. No, at the moment the /vendor mount point is not present and thus it's not supported.

Yes, this is for EUI at the moment.
XDA has had a little problem I guess or I have pressed the button to apply my XDA DevB project while it was spinning for more than a minute, wow! If any moderator can delete the other threads I appreciate, sorry for the inconvenience.
EDIT: 502 Bad Gateway but it posted, somehow.

Thanks, I'd like to update the thread on what the new version of today has but I'll wait a bit, it's just a classic (CAF) Kernel for EUI with patched battery phandle and faster charging compared to stock but still safe, same constants just a little faster due to updates and fixes I made in charger code.
Hope I can update this and the Pro3 thread as soon as possible with the new stuff.

@GalaticStryder highly appreciated that you chose to work on this device, really looking forward for this kernel to expand its compatibility to all roms, God speed!!

Working on eui 5.8 16s? Please tell me

Backup your boot partition and flash it over, I've only tested it on 26S but on Pro3 my Kernel ran on all versions I tested. Make sure you're not encrypted otherwise it won't flash (Indian 16S for example), to get rid of encryption you'd flash the latest Chinese version or one that is based on it.

My leeco set has this strange color calibration issue-its very warm and yellowish- due to which I don't use stock roms. I also am able to use only those custom ROMs which have color calibration or kcal built in. Is it possible to implement kcal support in your kernel? Thanks a lot.

Wow! It's awesome... Great kernel...

Same for me. But most people keep saying I am wrong. Not kcal, default color calibration in kernel should be changed, because it's invalid.

Could you dump what type of panel you have got and variant? Mine seems to be fine (truly) but I see the panel calibration has a few faults on the others from stock itself, and both open sourced codes for Max2 and Pro3 are the same regarding the panel, no updates.
Need to boot the stock Kernel again and dump all I can from Kernel logs or... reverse engineering.

If it is not excuse to ask, will be there any updates for Lambda Kernel for LG G2 ever?

Truly I guess. Screenshot:
I'm on Lineage 15.1 currently. To get it white I need to set LiveDisplay 9700K. Default color calibration looks terribly wrong.
Btw is your kernel suitable for Lineage 15.1? Or it''s for EUI only.

BTW, works perfectly on Le Max 2 Small eUI V18.
My screen seems yellowish cuz I turned on Reader Mode.
If turned off, my screen is white enough

Hey thank you so much for your kernel. I can't use EUI ROMs because when quick charge is on it never charges more than 1000mH.. But on custom ROMs I can charge my phone even with 4000mH. It's a life saver sometimes.. Does your kernel provide this feature for the EUI @GalaticStryder?

What is the battery life with this kernel?

Introduction
NOTE: This kernel is currently not being updated. Please use another more up to date one if possible.
Hello everyone, this is my personal kernel for the Pixel (sailfish) and Pixel XL (marlin). While I am not a super star kernel developer, I do know my way around it. My philosophy on kernels is pretty simple:
Follow stable Linux always. Updates will be delivered within 24 hours of their release to kernel.org.
Stable kernel rules work best (only add small things when possible).
Security and stability are paramount. Vulnerabilities are patched as soon as they are disclosed.
Features will be added only as needed (I have a list of things in the FAQ I will NOT add, even if requested).
Hopefully you enjoy
Important thread information!
I refuse to acknowledge/respond to bug reports that do not include clear steps to reproduce, a logcat, and a console ramoops (if random rebooting) or a dmesg (any other issues). Follow this guide to do this.
Keep things civil, I do NOT tolerate flaming of any kind.
OT is allowed.
Features
Here are the major features of the kernel (feel free to explore Github)
Up to date with the October security update (android-9.0.0_r0.21)
Up to date with the latest stable Linux version (3.18.125)
Latest binder and sdcardfs commits from kernel/common
Several subsystems converted to use power efficient workqueues
Mainline improvements to CFQ
Kernel hardening from CopperheadOS
Westwood as the default congestion algorithm
Sultanxda's wake boost driver
The following user facing features:
Backlight dimmer
Color control
HBM
Maple I/O scheduler
Sound control
USB fast charging
Wake gestures
Wakelock blocking
Vibration control
Latest WireGuard snapshot (0.0.20181018)
Built with a self compiled Clang 7.0 toolchain with a local initialization sanitizer
Hides bootloader unlock from SafetyNet (can still fail through other means)
Available to flash with AnyKernel2 (thanks to @osm0sis) [zip will automatically detect when Magisk is installed and patch the kernel so reflashing Magisk becomes unnecessary]
Downloads
Primary: https://github.com/nathanchance/marlin/releases
NOTE: Although the kernel's name is Marlin, it is for both Marlin and Sailfish (fully unified).
Installation
NOTE: These sets of steps should work for both initial installations and upgrades. All sane kernels on this device are just replacing the kernel image and maybe adding some cmdline parameters, which this kernel won't care about. If there are ANY issues after flashing this kernel over another, be sure to flash the stock boot image for your ROM, TWRP + Magisk if you want them, then the kernel before reporting any issues.
Through TWRP:
See their instructions for further information, you can install the kernel with TWRP temporarily booted or permanently installed.
Boot into TWRP.
Flash the zip (flashing Magisk is not necessary if you already have it installed).
Reboot and enjoy!
Through FK Kernel Manager (requires root):
Download the zip (and optionally, the md5) from my server
Tap on "Manual flasher"
Navigate to Download
Tap on the zip, select Auto-flash, and choose one of the options.
Reboot and enjoy!
NOTE: On custom ROMs, you must do a reboot between installing the ROM and installing the kernel/Magisk on a clean flash otherwise you may end up in a bootloop...

Frequently asked questions
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue, following this guide. If I can't reproduce reliably, I'm not going to fix the issue.
1.2 Q: Can you add xyz feature?
1.2 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration. I will NOT add the following:
Overclocking or underclocking of CPU or GPU
Undervolting
Any governors other than sched/schedutil
Any schedulers other than cfq
Anything that compromises performance
1.3 Q: How do I control the kernel?
1.3 A: I want to be very clear: the kernel does NOT need to be tuned to be useful. Most of the improvements are under the hood and don't require any user intervention to take advantage of them. In fact, if you don't know what you are doing, you could degrade the experience.
To control the user visible features of the kernel listed above, I recommend using either @franciscofranco's FK Kernel Manager (which has Flash Kernel support for downloading and automatically flashing the latest kernel zip along with some nice, user friendly ways for tuning the kernel) or @flar2's EX Kernel Manager.
1.4 Q: OMFG MY BATTERY SUXXXX PLS FIX!!!
1.4 A: The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone.
Thanks to:
The various other developers for their patches
@osm0sis for AnyKernel2
@franciscofranco for adding Flash Kernel support to FK Kernel Manager
@phantom146 for the thread banner
All of you guys for viewing the thread
A note about donations
Quite a few people have asked to donate to me in the past and I have turned them down. I am not in this for the money, this is my hobby, something I truly enjoy. If you truly want to donate to something (it is not expected in the slightest), I recommend an entity like the Open Source Initiative, the Free Software Foundation, XDA, or any one of the people I have thanked in the OP. Additionally, you are free to copy any and all of my work; the only thing I request is that you not ask for donations as well (though I can't really enforce this lol). Thank you.

You may notice the feature list is a little bare. I wanted to get a nice solid base formed first then add features in as requested. Please read the thread before requesting a feature; if it is already present, just press thanks.
In theory, this should work on P as I have merged the source in. I have only tested on Oreo though.

Add KCAL Color Control and I'm in. All I've wanted for so long is a stock like stable kernel with KCAL so I can tweak the display!
I ran your flash kernel the short time it was available for my old Nexus 6, happy to see this kernel here.

Thank you for bringing this to marlin!!

I tried another kernel on Android P preview 2 and had some problems. You noted that this kernel includes the source links for preview 2. The other I think only had preview 1. Would there be a difference?

@nathanchance I haven't had a change to flash this yet, I really enjoyed this from my 6P days. Can you tell me if HBM and backlight dimmer are available? If not, could I request them? Any wakelock blocks available? Possibly fingerprint scanner boost--NSFW Kernel has this.

I'll add HBM, backlight dimmer, and wakelock blocking. I'll take a look at fingerprint scanner boosting; however, the few implementations I have seen floating around lately seem like they don't work well.

Something occurred to me, the stock power HAL on this device doesn't support schedutil. Custom ROMs can add support easily so I'll still add it but I won't set it as default.

The tl;dr is these tasks get placed whenever is optimal rather than on a specific CPU core.

Hello everyone, this is my personal kernel for the OnePlus 5. While I am not a super star kernel developer, I do know my way around it. Hopefully you enjoy :highfive:
NOTE: This list fluctuates with versions, it will not always been 100% up to date
Here are the major features of the kernel (feel free to explore Github)

Just flash the kernel zip and reboot
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue, following this guide. If I can't reproduce reliably, I'm not going to fix the issue.
1.2 Q: What ROMs are compatible with the custom builds?
1.2 A: My daily driver is GZOSP so I test all the builds on this ROM but this kernel should work on other pie ROMs. If you are using a ROM with no issues, let me know and I'll add it here! If you are having issues, following the above steps and I'll attempt to fix whatever incompatibility there is. If I can't do it without breaking GZOSP compatibility, you're out of luck.
1.3 Q: Can you add xyz feature?
1.3 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration.
1.4 Q: How do I control the kernel?
1.4 A: I want to be very clear: the kernel does NOT need to be tuned to be useful. Most of the improvements are under the hood and don't require any user intervention to take advantage of them. In fact, if you don't know what you are doing, you could degrade the experience. To control the user visible features of the kernel listed above, I recommend using @flar2's EX Kernel Manager.
1.5 Q: OMFG MY BATTERY SUXXXX PLS FIX!!!
1.5 A: The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone.

}
Indroduction:
Weeb Kernel is based on latest CAF with a minimal import off OnePlus's provided source code to retain functionality.
Feel free to ask for any feature requests, but if I think something is useless or doesn't provide any benefit to warrant its addition, I will NOT add it, irrespective of how many people ask for it.
Code:
/*
* Your warranty is not void (Thank you OnePlus!).
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this Kernel
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/
Supports:
- Custom ROMs on 9, 10
-- WiFi will not work on ROMs that use qcacld as a module ( eg. Omni, Treskmod Pie )
Reporting Bugs:
If you want to report any bugs, please post a logcat and dmesg(using an app like syslog), thank you!
Features:
- Here
Downloads:
- Github Releases
Telegram Channel: Weeb weebmsm8998
Join me in my Café: // Weeb Karamel Café //
Flashing Instructions:
- Simply flash the kernel
- If you have magisk AND if you are on android 10, reflash magisk after flashing the kernel
Reason behind the name?
Well, I originally even thought about making this because of some mates in a weeb telegram chat. I'm aware of a kernel of the same name by raphielscape which is now renamed, and she was okay with me using this name.
Credits and Thanks:
- raphielscape for inspiration and dealing with my extremely stupid questions ( she is my sensei )
- osm0sis for AnyKernel3
- nathanchance, akhilnarang, MSFJarvis, kdrag0n, celtare21 et al for their help in totally random places :d
- The Linux Foundation, CAF and OnePlus for the code

Reserved for keks

Reserved for something idk yet

Weeb Kernel v2.22 CodeName: Pandemonium
Downloads:
OxygenOS // Custom ROMs // Omni based Custom ROMs (OmniROM, TreskMOD) // Hax (CodeName Phoenix, Dirty Unicorns)
Changelog:
- Compiled using AOSP Clang 9.0.1
- Upstreamed to latest CAF tag [LA.UM.7.4.r1-04800-8x98.0]
- Revamped EAS implementation [Thanks to Josh for the base and several backports by Kuran and some by others and me]
- Moved to using a 625 Hz timer
- Re-enabled KALLSYMS
- Added ULPS mode
- Performance cluster underclocked to 1958400 kHz - Does not affect performance significantly but has improvements in device temperature and some decent improvements in battery [Disabled by default]
Default setup:
top-app/schedtune.prefer_idle = 1
foreground/schedtune.prefer_idle = 1
top-app/schedtune.boost = 0 [My reason for the top-app schedtune.boost being zero is that we do not really need any boosting when nothing significant is going on, for example, watching a youtube video, or the network indicator changing every second or so. For this reason, I have set it to 0, it does not seem to affect UX in my testing and should be just fine.]
Dynamic Schedtune Boost = 15 [Duration: 1500ms]
top-app/schedtune.sched_boost = 15
CPU Boost = 1171/1056 [Duration: 500ms]
ZRAM Tuning:
swappiness = 8
dirty_ratio = 5
dirty_background_ratio = 2
Kernel variants:
#oos:- This is for OxygenOS. It should also work for HydrogenOS but it's not tested directly by me. I'm typically using this myself.
#custom:- This is for ROMs that use Lineage's implementation of the Qualcomm WLAN Module, that is, inlined and WITHOUT Sultan's hacks.
#omni:- This is for ROMs that use CAF's implementation of the Qualcomm WLAN Module, that is, as a module. eg. Omni, Treskmod
#hax:- This is for ROMs that use the Qualcomm WLAN Module as inline and with sultan's hacks to make it load during device init call. eg. CodeName Phoenix, Dirty Unicorns
Note:
Unfortunately, none of these work with each other, so each variant is for itself. Pick the right one before reporting that wifi doesn't work, thanks. Also, note that sometimes, on Pie, the ROM might just reject the WLAN module for no good reason and it's not unique to our device. I've seen and confirmed that this issue happens on other 4.4.x devices like Whyred as well.
To solve this, simply reboot or reflash the kernel. If neither of these work, dirty flash the ROM and then kernel again. If you're flashing Magisk, please flash it BEFORE the kernel to retain ramdisk changes (if) made by the kernel.
Announcement:
As of this release, I've decided to move the source to the [raphielgang] organization repository.
You can find the new source link for stable builds here.
Major thanks to @raphielscape and the rest of the people for their help.

runnin good on Tresk. thank you.

You consider making an aroma installer for the different versions? I whipped up a quick one here if you want to use it. <link removed>
It uses elementalx theme so you'll probably want to change that but functionally, it does everything you'd want

Thanks a lot, I appreciate it. But I personally like my zips small, and my script takes care of everything for me so it's not really any trouble. Nevertheless, I appreciate this a lot!

Oreo kernels worked on Pie so maybe the other way round too? idk I haven't looked into making it compatible at all. You could try removing the"9" in anykernel.sh in front of supported.versions, that may be enough but I'm not sure.
Personally I want to know if it works on Q

When running this kernel on CNP what should we set the power profiles option to in order to keep the stock kernel settings? Disabled or balanced?

Disabled. I have no idea what the power profiles even do, but disabled shouldn't interfere with anything.

With the new CNP update from last night, you'll be needing "custom" version and not "hax". Would appreciate it if anyone could confirm it for me, thanks!

Hello there

FAQ: (Read this before flashing the kernel and reporting bugs!)
Q. Gaming performace isnt good in this kernel!
A. Disable Samsung Hotplug from your preferred kernel tweaker app! Hotplug is disabled in builds from R2 onwards!
Q. Whats Fsync? should i disable it?
A. fsync transfers ("flushes") all modified in-core data of (i.e., modified buffer cache pages for) the file referred to by the file descriptor fd to the disk device (or other permanent storage device) so that all changed information can be retrieved even after the system crashed or was rebooted. This includes writing through or flushing a disk cache if present. The call blocks until the device reports that the transfer has completed. It also flushes metadata information associated with the file (see stat(2)).
Too scientific, didnt read! : In layman terms disabling Fsync gives you better performance with the risk of a Data loss/corruption during a system crash!
Q. I cant Flash NFS injector, FDE.AI, MAGNETAR and other tweakers on this kernel!
A. I have added a in-built kernel blocker to block installation of these so called "AIO kernel tweakers". You shouldnt install these tweaks in my opinion! If you still want to use a Tweaker, i prefer you use KTweak though i wont be providing support for issues if u have flashed any mods or anything of this likeliness!
Q. I have an issue and i have reported it in the XDA thread, yet nobody replied to me.
A. I might be slow in responding for issues reported in the XDA thread, if u want me to reply more faster, report it in the Telegram support group!
Q. My phone gets HOT while using this kernel!?
A. Short answer: It's your own issue, fix it yourself. Nobody makes a kernel just to burn your hands.
Long answer:
* Install Termux app from Play Store * Enable screen rotation, open Termux in landspace mode * Type this command: su -c top -d 2 * A list of processes will appear and refresh with 2s interval. Find which process consumes the most CPU usage with [%CPU] column and the package name in ARGS column. You should see the culprit of your issue.
Reminder: There is no such thing as "I have nothing in background but the phone still heats up". There definitely something happen and 99% of the time it's some of the rogue apps running in background.
Thanks to Diep Quynh for finding this one out!

I've tried it and for some reason left top corner of the screen never responded to touch. Ex: I couldn't turn on wifi from quick toggles n back arrow in some apps as I couldn't make a touch on left corner...
I didn't collect logs as I immediately reverted back to old kernel.

New kernel build is up guys! =)

Currently running the newest build, runs great, thanks for the work. 6h SOT and still 50% battery. Just wondering, any reason hotplug is disabled? Does it really impact performance that bad? Or is it just samsungs implementation? Tried to build a custom version using your source (with a big core oc and an undervolt), cant seem to for some reason. Once again, thanks for the great work. Any way to buy you a Coffee?

Hi mate!
1. hotplug is disabled cuz in my tests i found em to degrade performance and doesnt make much of a difference battery life wise, hence disabled and yes its a samsung implementation.
2. For OC u can pick ace2nutzers a2n kernel commits, i have tested em and it works
3. as for the undervolt, i havent tried em and probably wont be =)
4. Thanks very much, i dont need coffee or beers and stuff, u can hit the thanks button =)
Thanks and regards,
Stay Safe!

I am using this kernel on android 10 oneui
after i flashed the kernel i had weird issue concerning samsung clear case
when i close the case the screen turn on and when i open the case the screen turns off!
it acts in the opposite manner!

N950N supported?

is there any way to change to enforcing?!
