Hello there! I've been working on a new kernel for the OnePlus 7 Pro that I think our community will enjoy. I hope to bring a new viewpoint to kernel development that hasn't been seen previously in the dev community.
Philosophy
I just wanted to start off with the goal of my kernel. Draco Kernel isn't a feature-rich kernel, nor is it a performance-bias or power-bias kernel. Draco Kernel includes a collection of innovative commits (no backports or upstreams), designed to improve the efficiency of the device. Ideally, I will keep Draco Kernel up-to-date with the OnePlus official source code. The WiFi drivers will be imported from the latest 8.1-r1 CAF tag.
Upstreaming?
The reason I don't upstream is simply because I do not wish to risk instability in the kernel. Most people use their OnePlus as their daily driver, and I wouldn't want any potential panics or data loss due to a bad upstream. I'll leave the upstreaming to CAF and OnePlus, as they have the means for a more in-depth testing method.
Basic Features
Code:
- Minimal debugging and tracing
- No messy upstreams / backports that might cause issues down the line
- Performance and efficiency focused
- Multiqueue I/O scheduling
- Scheduler tweaks and hacks
- CPU governor adjustments
- ZERO in-kernel boosting while maintaining a smooth userspace
Advanced Features
This is just from the first official beta, so this list may change in the future.
Code:
- Remove AVB checks
- Disable SECCOMP (faster syscalls)
- Disable Audit (expensive in Android)
- Use non-blocking random pool
- Target small cluster in Makefile
- Disable IRQ debugging
- Don't use high-priority workqueue for usb policy_engine
- Schedule last-woken task for better cache locality
- Reduce cache pressure to keep cache valid for longer
- Increase vmstat interval to reduce intermittent jitter
- Adjust dirty ratios to writeback dirty pages later rather than sooner
- Do not collect I/O stats from block subsystem
- Don't dump oom_killed tasks
- Do not use UFS for randomness
- Disable ASLR fully by default (performance not benchmarked)
- Disable JTAG debugging by default
- Do not compile HIGHMEM (unused by our system)
- Do not compile watchdog (reduces jitter)
- BFP JIT (better networking performance)
- Increase haptic strength
- Allow GPU to sleep / nap
- Do not compile zRAM (unnecessary for this kernels MM settings)
- Do not perform readahead (proven to improve power and performance by 70%)
- Align scheduler timeslices with jiffies
- Overcommit memory for faster Android start times
- Remove a bunch of debug and tracing that is unnecessary for the kernel
- Remove schedutil hispeed boosting
- Remove iowait boosting (saves a large amount of battery)
- More that I forgot

Solved in new release
avid_droid said:
So I tried flashing over EvoX earlier,cause, I seen you ask for someone to test on custom r. Here's the results:
It's a no go. Stuck at bootloader and couldn't get out. Tried terminal to boot twrp and it was a fail. Only way out was msm tool back to stock. Not your fault as I've volunteered to do it.

That is concerning. Does flashing other custom kernels on EvoX cause that issue?
avid_droid said:
No

I think I found the issue. I didn't disable AVB checks on the /odm partition. I'll add this change right away. Thanks for testing!
Does this kernel come with KCAL?
Using Anxiety , better battery than stock. Thanks OP.

Just flashed and testing now, on the first look its pretty good and smooth. Will report back after 1 or 2 days, especially regarding battery life.

I disabled ram boost internally in the kernel. The slider will not affect anything. I usually leave at off just in case.
Is USB_ACM driver enabled?
If not then can you please enable it in the new release?

Hold the power button and volume up until it reboots,
then hold volume down and power to boot twrp.
This has happened to me way to many times. Take like 10-15secound for the first part
Bug
You have a bug in your kernel. My op7p can't read my usb it say's that there was a problem i can only format it and in an other device i have no problem

My USB via OTG is working fine here.
BETA #47
- Disable msm_performance and core_ctl
- Activate schedutil's hispeed frequency at 80% usage instead of 90% (lower direct input latency)
- Process I/O on the origin CPU to score a cache hit
- Set readahead to 128KiB instead of 512KiB (flash memory suffers higher latency with higher readahead)
- Check dirty writebacks every 1MiB rather than every 128 KiB (less jitter and keep cache valid longer)
- Reduce cache pressure to 50% (our RAM size can handle it)
- Load balance less tasks per scheduling cycle (lower latency)
- Compile DTBO in the kernel
- Remove iowait boosting from schedutil
CUSTOM ROMS ARE FIXED
Huge thanks to avid_droid and also @kaz205 for helping me test the builds.
Latest builds on github and telegram!

Extras:
UKM-Donkey_Edition_v2

Flashing Instructions:
- Flash through recovery (TWRP recommended)
- Flash UKM-Donkey Edition (optional)
- Clean cache (recommended)
- Reboot
- Install Synapse (optional)
- Enjoy (mandatory)
CHANGELOGS:
REFER TO MY KERNEL SOURCE FOR DETAILS ON EVERY COMMIT INCLUDED.
ON HOW TO HANDLE CHARGE_LEVES INTERFACE (proceed with caution, if you don't know what you are doing, just don't do it... I won't support any mess ups with this option!)
- You'll find the sysfs interface for this in this path: /sys/kernel/charge_levels
- The charge_level_ac file contains the value for the wall charger rate in mA; if the file contains a 0 value, it will charge at the standard rate, anything else will be user handled; values should go not more than to the 2100 limit.
- The charge_level_usb file contains the value for the usb charge rate in mA; if the file contains a 0 value, it will charge at the standard rate, anything else will be user handled; values should go not more than to the 500 limit.
- Te charge_info file provides info about the rate in mA and voltage when the phone is charging.
ON HOW TO APPLY ZZMOOVE PROFILES: For now, use Kernel Adiutor, Synapse or any other kernel tweaker to select Zzmoove as the Cpu Governor, and under Governor Optimizers (or in the Sysf folder) and choose the profile_number of your choice:
1 - for Default (set governor defaults)
2 - for Yank Battery -> old untouched setting (a very good battery/performance balanced setting DEV-NOTE: highly recommended!)
3 - for Yank Battery Extreme -> old untouched setting (like yank battery but focus on battery saving)
4 - for ZaneZam Battery -> old untouched setting (a more 'harsh' setting strictly focused on battery saving DEV-NOTE: might give some lags!)
5 - for ZaneZam Battery Plus -> NEW! reworked 'faster' battery setting (DEV-NOTE: recommended too! )
6 - for ZaneZam Optimized -> old untouched setting (balanced setting with no focus in any direction DEV-NOTE: relict from back in the days, even though some people still like it!)
7 - for ZaneZam Moderate -> NEW! setting based on 'zzopt' which has mainly (but not strictly only!) 2 cores online
8 - for ZaneZam Performance -> old untouched setting (all you can get from zzmoove in terms of performance but still has the fast down scaling/hotplugging behaving)
9 - for ZaneZam InZane -> NEW! based on performance with new auto fast scaling active. a new experience!
10 - for ZaneZam Gaming -> NEW! based on performance with new scaling block enabled to avoid cpu overheating during gameplay
11 - for ZaneZam Relax -> NEW! based on moderate (except hotplug settings) with relaxed sleep settings (to react audio/bluetooth/wakeup issues)
Thanks for this man, Just downloaded your unofficial omni build and now this.

Not really, I'm still testing -and will probably keep tuning- hotplugs and governors. I'm even considering adding Bricked Hotplug too.
The beauty -in my opinion- about Omni is how solid it works. With other roms I've allways stepped into A or B annoying bugs. Not talking down about anybody's work, but even when Omni takes more time to add features, things work better, and I like that. Plus these guys are making a true open source project, not meaning to bloat our experience with the goal of making money -like CM theme manager- but again, that's just my point of view.
Back to the kernel, there's still work to be done. For now, at least I'm getting a much more acceptable battery drain and, in my opinion, a very good idle/deepsleep drain. Yet I'm not too fond about excesive options, and 3 hotplug drivers qualify as way too much to choose from. I love mako_hotplug because of it's simple and clean approach, that's why it's defaulted. But I might find some other works better in lollipop. So please toy with settings and try to find ur better config. And... report back if you can, I could use the feedback.
Thanks for downloading and trying out.
Looks like a very interesting kernel for the omnirom!
What does the 'quick wake up' feature exactly do? Does it remove the slight delay between pressing the power button and the screen turning on?
Could not really find something describing it on google.
Omni is using cpuquiet hotplug, right ?
Is it working good ?

Yes, of course. Currently running the oc version with pixel dust GSI.
Btw this kernel is for android 9.0.
Feels good to see Nokia Dev community getting started.
Does this root method work on stock pie, December patch, even without flashing the kernel?
And also do you have gapps on your gsi? If so, how did you flash them? I was trying to install aex gsi, but it's a bit unstable and also no gapps

Yes. For Gsi you need to resize system partition after installing it, so you can install gapps.
Or just flash pixeldust gsi.

https://mega.nz/#!VhFVFYpZ!QBOan6WuHJMzRr0N5uI9MZJAkbhTZMyjgcKGqXppqrk
In this relase there are also other battery saver tweaks. Let me know if the uv its stable. Thanks.

Patched to get more performances without root
(patch zip included below)
AOSP-Extended
Download:
CLICK/TAP HERE
FAQ:
Q: Z00L?
A: i only have Z00T,but i did built it for you, if something goes awfull dont blame me and specify what kinda things happen (if possible, with logs too)
Q: If i've install this on my rom, does it will cause same bug that happen under lineage16?
(For example you're using RR-6 or GroovyAndroid 7.0)
A: No, that was rom bug under Pie custom rom we currently have that unfortunately i couldn't fix unless i find it, fix it and test whole things, i build this kernel for my personal uaage
(For example RR-7.0, Lineage16,AOSPExtended V6.0)
Q: I Want this FEATURE
A: sure, i'll think about it and try merge it later if i have time
Q: Help, There is something WRONG
A: send me your log in proc/kmsg or from log apps
Q: What are you gonna add next?
A: More IO, Governor, Patch, Filesystem Fixes, etc.. if i forgot something please remind me
Q: MSM-Thermal was bugged, it keep enabling itself
A: Dont ask me, i dunno why too.. just delete thermal.conf in system/etc/ to disable them FOREVER
Q: Can I Use F2FS?
A: You can, if your rom support it and also our fstab only support /data f2fs, i might modify it to support cache and system too but for me /data was enough, or you could try messing with that~
Q: When you're gonna release kernel updates?
A: As long i have time to do it and there is something i want to merge, since i also use this kernel as daily driver (My Phone was Z00T).
Known Issues:
My Unity Games Freeze after a slight Stutters!

Does it improve battery life on lineage 16?

if you install it, and change CPU Governor to blu_active it will save more battery than interactive/ondemand while retaining good performance, it also have "fastlane" mode in governor option to scale faster (good for gaming), i recomend to use it and set min cpu to 200mhz.
You could also try Zen if Maple didnt work really well for you~ other than that,this kernel also have performance improvement than your lineage16 because i fork it and apply various change that will accumulate from now.
if you want a very good battery life Try This Kernel Configuration:
Disable MSM Thermal by deleting/moving every thermal-engine.conf you could find under system/etc/
Set min cpu 200mhz and max 1,1ghz(big),800mhz(little), change governor to blu_active or use powersave for extreme low power usage since it scale very slowly
(Note:not recomended, i rather use blu_active)
Also disable perfd to make sure your system didnt change anything on your CPU settings
if your phone was Z00L variant, 800mhz was better than making your phone goes higher
(higher than this will use more voltage and cause more heat, even thermal lock your phone into maximum 800mhz most of times)
Set CPU core big min 0, max 4, little min 4, max 4
Disable any touchboost if you had any configured
Use Maple>Zen>SIOPlus (try any of this three)
Set GPU Max 400mhz, Target 400mhz, min 200mhz, for extreme battery saving measure change governor from msm-adreno-tz to powersave
Disable Zswap,Zram
Reduce Entrophy Amount to 64/128
(Also your choice to disable or enable add random)
Disable Gentle Fair Sleepers
Enable I/O Stats
(some apps maintain performance and usage by using this especially mobile games that use Unity)
I might add hotplug later for better battery usage and see if that can be merged also work, hotplug function was managing core better (on/off itself) than system especially since our device usually have 4 little core allways online.
(it wont scale automatically, dunno maybe bugged that's why i've said little core min 4 to make sure there is no lose in performance caused by system for using power-efficient little core less than 4)

i am very sorry, i am doing this on git-web instead of pull and push commit like everyone else did, its really bad right.. and yes, its build using travis instead locally.. currently im pushing new build using linaro-8.3.
Edit: Build pass, everyone can try if they want it
Okay, enjoy 0.1c~ do tell me if you run into problem especially Z00L because i've only test run Z00T.
Note: do read .zip name properly so you didnt flash wrong variant for your phone
For Every Z00T User, i heavily recomend you to flash new 0.1c build for fixing your cpu display and minor kernel error silent
Z00L 0.1c was available now
What Changes Included:
Restored CPU Info
Fix kernel error loop caused by bw_hwmon
(it barely have effect, but why not?)

Hello there! I've been working on a new kernel for the Redmi Note 9s that I think our community will enjoy. I hope to bring a new viewpoint to kernel development that hasn't been seen previously in the dev community.
MUST CLEAN FLASH ROM THEN FLASH KERNEL TO PREVENT LAGGINESS
Philosophy
I just wanted to start off with the goal of my kernel. Illyrian Kernel which is based off of draco kernel isn't a feature-rich kernel, nor is it a performance-bias or power-bias kernel. Illyrian Kernel includes a collection of innovative commits, designed to improve the efficiency of the device. Ideally, I will keep Illyrian kernel up-to-date.
Problems?
-Weird manufacturer error on bootup, only pops up once after every restart (miui only) - FIXED
Upstreaming?
Has been upstreamed to the latest v4.14.183 linux kernel stable
Basic Features
Code:
- Minimal debugging and tracing
- No messy upstreams / backports that might cause issues down the line
- Latency focused
- Anxiety I/O scheduler
- Scheduler tweaks and hacks
- CPU governor adjustments
- ZERO in-kernel boosting while maintaining a smooth userspace
Advanced Features
This is just from the first official beta, so this list may change in the future.
Code:
- Remove AVB checks
- Disable SECCOMP (faster syscalls)
- Disable Audit (expensive in Android)
- Use non-blocking random pool
- Target small cluster in Makefile
- Disable IRQ debugging
- Don't use high-priority workqueue for usb policy_engine
- Disable profiling (kdrag0n)
- Anxiety I/O scheduler (sync read priority)
- Schedule last-woken task for better cache locality
- Reduce cache pressure to keep cache valid for longer
- Increase vmstat interval to reduce intermittent jitter
- Adjust dirty ratios to writeback dirty pages later rather than sooner
- Do not collect I/O stats from block subsystem
- Don't dump oom_killed tasks
- Do not use UFS for randomness
- Disable ASLR fully by default (performance not benchmarked)
- Disable JTAG debugging by default
- Inform kcompact of fragmentation moreso than full RAM usage
- Do not compile HIGHMEM (unused by our system)
- Awaken kswapd at 1% (80mb free left) instead of 0.1% (8mb free left)
- Do not compile watchdog (reduces jitter)
- BFP JIT (better networking performance)
- Force block requests to execute on their origin cpu (better cache locality)
- Increase haptic strength
- Allow GPU to sleep / nap
- Do not compile zRAM (unnecessary for this kernels MM settings)
- Do not perform readahead (proven to improve power and performance by 70%)
- Align scheduler timeslices with jiffies
- Overcommit memory for faster Android start times
- Remove a bunch of debug and tracing that is unnecessary for the kernel
- Remove schedutil hispeed boosting
- Remove iowait boosting (saves a large amount of battery)
- Do not expedite RCU
- Halve round-robin timeslices
- Expedite wakelock garbage collection
- Lower I/O request limit for lower latency
- More that I forgot

Can we flash this with fastboot flash boot?
wow! its good to see some passionate devs putting some efforts with this phone....waiting for the price to drop cz its being sold at twice the original price in my country ;__;
I like it when we meet someone who loves what they do! The kernel is perfect, using miui.eu, dirty flash, without choking or something, just one question is this kernel focused on being balanced?
Dirty flashed it. Xiaomi.eu 11.0.8. Works great
UI responsiveness is better compared to stock kernel. no lagging.
Nothing breaks. Wifi, bluetooth, in call audio all working as it should.
GPS? not tested as i rarely use gps.
Keep up the good work OP and thanks.
Thanks for the kernel! Do you plan adding wireguard kernel modules? Cheers

Pls give some review to improve better and better
All look good thus far! I'm in the middle of searching what causes my phone to reboot while charging for some weeks now, one thing to do was flashing another kernel but no luck
Apart from my issue, phone is very snappy, no hiccups at all. Idle drain looks great. All functions work as they should, BT with smartwatch and car display. Stable wifi and data connection, stable GPS.
So all good!!
I will try this for a while but on the first run everything is good and get one of the best result on geekbench.
It is working fine for me but I think it is messing the otg flash drive. it is always "the disk need to be check" something after I used my otg so I can't use it the next time. It's fine though when I'm on OD kernel.
@Zeetaa
Thanks for your kernel!
I installed your kernel (+ BatterySaverModV1.1 flashed with Magisk) yesterday and can now compare it with ODK 11.21 (based on Immensity) regarding battery consumption.
I use a standardized scenario that always runs the same and roughly corresponds to my usage. Touch interaction (browsing, messaging) is completely missing in the scenario, because that is difficult to standardize (for me).
Full charge to 100%.
1hr NewPipe (WiFi, always the same video)
1hr call (LTE)
1hr video recording
8hrs idle (in flight mode)
1hr NewPipe (WiFi, always the same video)
2hrs Idle (Cell standby)
All timings are exact. The phone is always at the same place and in the same position. The brightness of the display is always the same. Apps that I do not actively use are frozen. A triggered autostart of these apps is prevented. The OS of the phone is Havoc 4.11. I note the battery level after each step.
Results
Unfortunately, I can't tell yet if it's because of the kernel or the installed mod, but the consumption is slightly higher than ODK, espacially in idle mode. The difference isn't huge, but noticeable.
In the 8hrs that the phone was idle and in flight mode, it consumed 2% with Nexus, but 0% with ODK.
At the end of the scenario, 66% of the battery was left (70% with ODK).
I will test tonight how my phone behaves when I use the BatteryMod together with ODK. Then I will see the influence of the mod.
I agree with @esszett conclusion, while we do have the same result on benchmark and gaming. The battery is worst than OD 11.25 (I am using AICP)
Hey, could one of you please send a link to that batterysavermod? Thanks.
@Zeetaa
Yesterday I started the new scenario with ODK (11.25) and BatterySaverMod. What I can say so far: It is the Nexus kernel that causes the higher drain, not the BatterySaverMod. However, whatever the BatterySaverMod does in detail, it has no effect on my battery in my usage pattern.
