Thanks for the update arter97! However my visual voicemail disappeared!

Edit: Disabled all magisk modules, reinstalled kernel, and got it back on, reinstalled magisk modules, it's still there. All good!

Hi, anyone tryed this kernel on crdroid 7.4 or Derpfest? (Both are android 11, but based on aosp). Both uses the crdoid kernel:

Somehow the bootloader etc should be based on android 10, because twrp still works...
Thats why i ask xD
Cheers

Today Oxygen updater says android 11 stable is available for my OP7. I'm really undecided, android 11 has AOD, but android 10 has arter kernel. I don't really wanna lose the smoothness... I guess I'll stay on android 10 for a while

A11 runs pretty much perfectly for me on my OP7Pro now, after a few hiccups at first.

How do you think a bootloader (which is part of the manufacturers official firmware) gets an update through an unofficial Software build?

i wrote that the bootloader is from android 10 and the crdroid kernel+os is android 11.

because as far i understand, the kernel here isn't compatible with oos11.
But the crdroid 11 kernel, shouldn't be much different from this here.
That's why i ask.
Here is an another example that works with oos10 and aosp10/11.


So why the hell you conter my question with your unrelated nonsense question?

All what i want to know is, if it works with aosp11.

If you look closely at the linked kernel decription, it says it is a unified kernel for Android 10/11. So it means it is a kernel which has modifications for both Android 10 and 11 which gets (de)activated for the Android- Base you are running on your phone

The OP of this kernel clearly says:

r30 and up only supports Android 10

So as long as Arter isnt stating something else, you can safely assume that this kernel is not compatible with Android 11. And why i was asking that Question? To make you rethink your assumptions, because you are basing them on a wrong understanding on how parts on your phone are tied with each other (or not). A kernel or a rom can be tied to a certain firmware but it doesnt have to. So what does it means for your question? While crdroid and their kernel and any other rom can run on a Firmware released for Android 10, it doesnt mean everything can run together with a Android 11 Rom base. OOS Android 11 will most likely (but not necessarily) come with a firmware update, which will be required to install it

What does the bootloader have anything to do with this?

This kernel does not support custom ROMs, if if did, then it would work with AOSP 11 roms (not for long though).

This kernel is strictly OOS10 only.

Hello there :)

This kernel is amazing and works great. Im currently running r65 on my oneplus 7t on newest android 10, without a issue. I have a question in terms of cpu tweaking and I hope someone can help me out with this one.

I love the fact that I can tweak my cpu performance with my rooted phone (for ex. with kernel auditor), cause it makes my phone, even with this efficient kernel, run like 30% longer in powersave profile. Unfortunaterly I can't enable the alternative cpu profile "powersafe" since a couple versions earlier of arter kernel(Symptom when profile "powersafe" is selected and the button "CPU-Govenor-Settings" is pressed: Message something like: "powersafe cant be selected~" in english). If someone who has an idea what to do or how to add powersave values/profile to arter kernel can help me out, I would be more than grateful.

r70a1 is up and it "could" be a major release.

r70 brings a major change in certain subsystem in the kernel that affects battery life, performance and memory management.
Because I want feedback from blind tests, I'll keep the changelog to myself at this point.

Because of something I've changed, you must use your phone for some extended period of time for it to fully kick in.
DO NOT provide feedback in less than 36 hours after installing the kernel.

Also, this version of the kernel now directly affects the system-related partition on your device.
Nothing can catastrophically damage your phone, but as always, back up your data.

I've been testing this build for several days now, and it seems stable enough.
While I don't expect any random reboots, I'm still marking this as an alpha build.

    Hi mate, thnx for the update, I installed it and it works great

    Is it possible that there is a change in the loudness of the headphone speaker when watching media? It seems to loud to me

      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.

      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.

      /* 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.

      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.

      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.
