Hello guys, do not tell me the FKM program, does it need to be configured somehow after installing the kernel? And is there an instruction on how to do this, if at all?

I'm sorry if this has already been asked... But i don't find any search function threadwise in that xda app.
Is flashing over another kernel a problem? Do i have to go back to stock kernel first? Thanks in advance!

Depends on the kernel you are coming from. But it's safer.
Bluespark modifies the boot image, and also ramdisk as well as the new vendor_boot. So if you are coming from that, you need to flash both the stock boot.img as well as stock vendor_boot.img first, and then Omega.

Any chance to make the charging behavior more aggressive while the screen is on or not sleeping? Similar to blu's? I don't like the idea of having a kernel prod around other partitions besides the boot/kernel itself.

No. I'm not going to break thermal throttling just to have people charge faster. There is a reason thermal throttling exists - to protect your phone.
Thermal throttling used to be broken on Omega as well, until I fixed it. Now it's behaving exactly like stock, which is good.

Can I request to update WLAN/WiFi drivers, as on all previous OnePlus phones and this one I found the default wifi drivers to not be good , and the performance improve with kernels which use different/updated drivers.

Nope, sorry. I actually tried, with multiple CAF tags, and battery life was significantly worse with anything other than the stock WiFi driver version.

    New kernel release!

    Changelog:
    - Further tweaks to GCC's O3 optimization level
    - Pulled in a number of stability fixes from CAF
    - Pulled in a UFS system fix from CrDroid kernel
    - Removed even more logging from the kernel when the phone is not connected to WiFi
    - Reverted to Westwood as default TCP congestion - BBR is still there and can be enabled
    - Disabled OnePlus's TPD module - this was responsible for limiting apps' CPU placement, as reported by multiple news outlets

    Enjoy!

    There might be a light at the end of the tunnel: we are currently testing a new build, with TPD disabled, and idle drain normalized! :)

    I would let the users decide whether you want battery or performance and upload two versions one without and one with TPD module
    He stated that there are issues outside of performance and battery life with the kernel. Also, this is his kernel, his work. I assume he takes pride in providing a polished product, and that is why he is choosing to go the route he's going.

    <rant>
    For anyone complaining about the TPD module and performance, go compile your own kernel with TPD disabled, if you can't, then accept what the developers of the kernels for our device are creating and appreciate that we have that. Tired of seeing people come into these threads and act like spoiled children, the developers owe you literally nothing.

    New kernel release!

    Changelog:
    - Using Clang to compile (stability reasons)
    - Tweaked Clang's LTO for better performance
    - Re-enabled Oneplus's TPD module (stability reasons)
    - Pulled in 3 stability fixes from CAF
    - Re-enabled watermark boosting - now that a fix for it is available in upstream

    Enjoy!

    If you don't mind me asking, what issues did you run into by disabling the TPD module?
    Slightly higher active drain, but significantly higher idle drain.

    Introduction

    Hello everyone, this is my personal kernel for the OnePlus 9 Pro.
    My philosophy on the kernel is pretty simple, intended to replace the stock kernel, but with a lot of under-the-hood tweaks.

    Hopefully you will all 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, no flaming in the forums!

    Features

    • Up to date with OxygenOS 11 source
    • Compiled with Google's Clang toolchain for maximum stability, with all warnings and errors fixed
    • Compiled with Clang's cortex-a55 optimizations
    • Many tweaks under the hood for smoother UX, lower battery drain, etc.
    • Westwood as the default congestion algorithm (BBR is also available)
    • Available to flash with AnyKernel3

    Thanks where it's due

    @pyry666 for all his help getting me logs after logs after logs. Without him this wouldn't have been possible!
    @Burt Squirtz and @crashazz3 and @TheKnux for helping to test
    Kerneltoast for his extreme patience and guidance
    osm0sis (for AnyKernel3)
    @eng.stk for finding a way to have proper hardware detection working

    New kernel release!

    The test team has been crazy busy, flashing sometimes 5 builds a day to pressure test, and come up with this new kernel.
    After tons of performance tests, we found that Clang (with the included optimizations) outperforms even the best GCC builds, so I'm now moving to using Clang by Google to compile the kernel.

    Changelog:
    - Fixed major network error where userspace was trying to modify network settings but the kernel wasn't allowing it (this issue is also present on stock kernel)
    - Pulled in a fix from CAF to improve/lower battery drain
    - Updated Wireguard module to latest version
    - Built using Google's latest Clang (12.0.6)
    - Enabled all Clang internal optimizations (reverted a crazy CAF patch disabling them), and fixed all subsequent code errors
    - Fixed an IRQ saving issue found via lockdep (upstream)

    Enjoy!

    New kernel release!

    This is a huge one in terms of stability and smoothness.

    Changelog:
    - GCC LTO implemented
    - GCC O3 optimization (together with LTO results in significant improvement of hackbench scores)
    - Wireguard added
    - Anykernel 3 updated
    - Critical and stability fixes from CAF
    - More code fixes based on GCC's diagnostics
    - Significant improvement to ZRAM speed

    Enjoy!
