    Hi,
    I'm not sure how standard (triggered from Magisk Manager) Magisk's update works. Does it interfere in any way with my actual configuration (which is stock 10.0.15, magisk 20.4 and arter's kernel) ? I mean, should I proceede some additional tasks after upgrade to magisk 21, like reflashing kernel or anything else ? Or just install v. 21 from Manager and reboot ?
    You can install from Manager and reboot. Dont need to flash the kernel again :)

    Hey,
    Thanks for the reply.
    So just to clarify you flashed arter kernel on top of blu_spark without reverting to stock?
    I think I'm gonna skip the liveformat part cause I don't wanna lose any data too much of a hassle to set everything up again right now.
    Thanks again.
    Sorry for the very late reply.
    As per the above, no need to revert to stock. Just flash this kernel over blu_spark or anything for that matter. Magisk and root will be unaffected. First boot will take longer than usual but you'll know your not in a bootloop because the animations haven't slowed down.
    As per liveformat, it seems it does not work on oos 10.0.13 stable and even the latest magisk beta 21.3. There is no word from the main man on this issue.

    Np.
    Thank you I flashed it without reverting to stock and it's running very good with no issues so far.
    Idk about the latest oos cause I have the indian version which has 10.3.7

    So here's a little anecdotal experience with the kernel and my recent shift to a 7T.

    I have been using arter97's kernels since the S3 days when he probably first arrived in the modding scene. I have been using his stuff for years now and it has been such a breeze every single time. The idea is just flash and forget. Never got any issue with regards to battery drain or performance. I upgraded to a 3T and just jumped to his kernel after he announced his kernel port.

    Now with the 7T. I'm running complete stock OOS 10 with the kernel on top. Idle drain is nearly non-existent. I can go without charging my phone overnight and still have enough juice to last me an entire day. His work is almost magical and the shift to f2fs provides smoothness in the overall experience that I haven't experienced ever. The worst offender is the decryption problem by OnePlus but even that didn't stop me from using his work.

    Android usually requires a restart to help with performance if it becomes sluggish after a while but this dev's work is honestly the best kind of combination between performance and battery life. I can't be thankful enough for people like him making the experience of Android smooth as ever and will continue to use it for years to come. Rock on man! Your work is the only I stick around with xda and the modding scene. Otherwise there's not much reason to flash stuff these days as Android has significantly matured to work absolutely fine compared to the likes of iPhones even. Even better in some cases.

    /* Details */

    - Fully rebased kernel without unnecessary OnePlus' code -


    This kernel is not based on stock OxygenOS kernel source provided by OnePlus. Instead, it’s based on the latest and greatest Qualcomm has to offer. Only the necessary parts from the OnePlus kernel has been cherry-picked, such as OnePlus 7 specific device drivers.

    This brings 2 major changes: less debugging code and an overall lighter kernel.

    There are miscellaneous changes made by OnePlus that are supposed to maximize utilization of system memory. But seeing how it’s implemented(heavily relying on zram and a physical writeback swapfile), I decided to remove it entirely.

    Users are recommended to disable the “RAM Boost” feature from Settings > System > RAM Boost.

    Due to the completely different base, the memory management with this kernel will be drastically different from other kernels.

    - Latest CAF msm-4.14 kernel fully merged -

    This kernel is also constantly merging the latest Qualcomm Android 4.14 kernel. This tag contains more up-to-date changes from Qualcomm than the regular Snapdragon 855 tag(sm8150).

    - Use CONFIG_HZ = 300 -

    This changes the context switching interval from 10ms to 3.33ms. Pixel used this for years and Google recommends other vendors to do the same for less jitter.

    This is even more important on displays with higher refresh rates.

    - Optimized power configuration -

    Stock OnePlus configuration forces display-related processes to use the Gold cluster(formerly known as big cores) exclusively.
    This configuration brings a huge power regression since it makes every frame dispatch to wake up and use Gold cores.

    This kernel resets this profile to use the configuration Google recommends, which is to use the Silver cluster(formerly known as LITTLE cores) exclusively instead. No performance penalty was noticed with this change while massively improving battery life.

    - BBR as the default TCP network congestion control -

    BBR is a (relatively)new TCP congestion control developed by Google, and it’s regarded as one of the best things you could do to your network configuration. You can find its benefits easily just by Googling BBR. I’ve been personally running BBR for months on various Linux machines including the server running arter97.com and it’s been great.

    Now that our Android kernel is running v4.14, I’ve enabled BBR and backported other BBR changes from mainline.

    /* Notice */

    5G variant is unsupported.
    Only OxygenOS is supported, but it is likely that the kernel will work with other ROMs. Though you may encounter minor issues.
    Feel free to tip me which commits are needed to fix other ROMs.

    /* f2fs */

    OnePlus 7T and OnePlus 7T Pro users cannot use f2fs without involving heavy and risky repartitioning operations due to Dynamic Partitions.
    r61+ allows using f2fs on OnePlus 7T and OnePlus 7T Pro.

    This kernel fully supports f2fs for /data and I encourage everyone to use f2fs with my kernel for better performance.
    See here as to why you might want f2fs.

    The process differs with T and non-T series.

    /* T variants */


    The kernel now detects whether the userdata is in f2fs format and patches fstab on boot for OnePlus 7T and 7T Pro users during boot.
    This is done in a volatile manner, which means your system files are not modified and using other kernels will revert the effect.
    This is half of the puzzle.

    The other half of the puzzle is to getting userdata partition into the f2fs format.
    Due to lack of a proper recovery for the OnePlus 7T, I patched up f2fs-tools to support formatting while the Android is up and running.
    You can use Franco Kernel Manager's flasher to flash the live-formatter.

    This obviously removes all data on the device.
    Please make sure your data is fully backed-up.


    f2fs live-formatter:
    https://arter97.com/browse/f2fs/liveformat

    Existing f2fs users won't be affected by any of these changes.
    Note that the OnePlus 7T and 7T Pro's OxygenOS has an issue handling FBE(File-Based Encryption) with f2fs(which is presumably why they left it out while the OnePlus 7 Pro had it), and encryption will be disabled when you use my kernel's f2fs live-patching feature.

    Without encryption, your entire data will be in danger if you lose your device.
    Please use f2fs if you understand this trade-off.
    (Non-T series users can safely use f2fs with encryption.)

    f2fs installation steps:

    1. Download and install my kernel.
    2. Download and install f2fs live-formatter.

    OxygenOS OTA steps:
    1. Install OTA and DO NOT reboot.
    2. Download and install my kernel using Franco Kernel Manager.
    3. Reboot.

    Re-format into ext4 steps:
    1. Use stock recovery and perform a factory reset.

    Re-format into f2fs steps:
    1. Use stock recovery and perform a factory reset and turn the userdata back to ext4.
    2. Reboot to Android.
    3. Download and install f2fs live-formatter using Franco Kernel Manager.


    /* Non-T variants */


    TWRP is not integrated to the kernel.
    Please use a TWRP installer to install TWRP on top of my kernel.

    To use f2fs, simply format /data to f2fs with TWRP.

    Afterwards, flash f2fs-optimize.zip from http://arter97.com/browse/f2fs/optimize

    There’s no need to flash separate zip files for replacing f2fs-tools or fstab.

    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. Hard. A lot.

    It could be possible that we wont see arter kernel on Android 11. Arter mentioned it in the telegram group, he us extremely Busy and dont know when and if he continue this Kernel. I can understand cause this is hell of work.... Arter is the guy that changes every Parameter of a kernel to make it perfect...

    Boy I sure hope we see an arter kernel for android 11. I just updated to the beta 2, which is running great by the way, but the smooth responsiveness of the arter kernel is definitely not there lol

    Hi guys. I went through the entire thread but being new to custom kernels I'm a bit confused and not sure how to proceed.
    I've just flashed the newest oos 10.0.11. After that, twrp keep, magisk and Rice. So i'm rooted, with stock kernel, rebooted several times and want to give Arter a go. I don't want to switch to f2fs. I just want the kernel.
    So, do I just flash it via FKM or are there any other steps I should take?
    Sorry for the noob question and thanks for your time.

      Why do y'all keep asking lol? I'm sure once it supports 11 arter will let you know in his changelog.

      Until then: No, for OOS 10 only.
      1
      Since it's understandably a little quiet, I hope you'll excuse this question: is there a way to disable the OOS11 upgrade notification? I won't switch until Arter kernel is ready, but I'm sick of looking at it.

      Code:
      adb shell pm disable-user --user 0 com.oneplus.opbackup

      or drop the adb shell if you're using Termux or similar directly from phone.

      A major update r50b1 is up.
      This isn't for PA. This version is for OxygenOS.

      Recent OnePlus' kernel breakage forced me to look into cleanly disabling OnePlus brain service, and I think I managed to remove it "just enough".

      Similar to how my Pie kernel was made, r50b1 now removes pretty much all of OnePlus' own kernel hacks. As a result, users no longer have to worry about recent OxygenOS version's compatibility issues.

      Since we no longer need OnePlus' hacks, the kernel has also been rebased cleanly on top of latest Qualcomm's Android 4.14 kernel and incorporates more patches that I missed previously.

      As this new r50 version differs significantly from my previous Q kernels, I felt the need to mark this as a beta for possible regressions, but I've been using the new kernel for couple of days now and I'm happy with the results.

      You may experience differences with battery life or general performance, both positively and negatively.
      Please share your feedback.

      Initial release

      r40 is up and it's a major update.

      I'm expecting this to be my last OxygenOS kernel in preparation for full-time AOSPA development. I won't be updating this OxygenOS kernel unless a critical issue pops up.

      7T and 7T Pro supports are added and due to TWRP not working properly there, you can use FK Kernel Manager for installation.
      EXKM is unsupported due to weird installation issues and it's not worth my time to fix.

      Note that neither of those device can use f2fs due to Dynamic Partitions. You'll have to do a heavy and risky repartitioning like I did for f2fs, which I don't have the time to write down a tutorial.
