Working very well on 099, thank you for your work.
Some small suggestions: the maple occasionally causes the UI animation to drop frames. After I tried FIOPS, ZEN, SIO, CFQ, and maple on the essential, I think the best is SIO, and developers are advised to add it.
And maybe you can consider the support of interactive, so that people who use stock rom will have a stable setting.
Thank you again for your work.

Nah... Maple is out anyway...

Nah... CFQ is actively being developed...

Nope... Interactive does not work on EAS...

Just a heads up, I'll be rolling out an update in much quicker succession than I typically would in order to address some stability issues which have been brought to my attention, i.e. lockups and subsequent reboots. Seems as though the frequency and severity varies among users, but I imagine some of you have encountered similar behavior despite the lack of reports. Regardless, I'm aiming to have maintenance update out by the end of the week. I'll try and cram in as many goodies as I can between now and then to make it at least somewhat significant.

I installed the 167 version of the kernel, in the phone reboot, stuck on the startup page, also can not boot to recovery, and finally had to go back to the official kernel, and then brush into the 161 version of the kernel, 161 kernel does not seem to have this problem.
Thanks to the developer's hard work ~

Not sure what to tell you on that one, I'm fairly confident in the recent build, and everyone else that's used it thus far have only affirmed that the reboot issues that were present on Hercules have been corrected. As far as the phone not booting, and being unable to boot into recovery, this is the first time I've heard anything of the sort about any build I've ever released. Makes me think there's something larger at play here, but regardless there's not a whole lot I can do based on your reporting with no subsequent logs. I'm sorry you had this experience and you are of course free to use whatever you see fit, but I'd hope that this anecdote does not discourage others as I built and tested this lastest release on stock, and all of these builds are tested amongst the telegram group on various ROMs before they hit xda. That's not to say things can't slip through the cracks, but I would have never released something that exhibited such extreme behavior.

Yep, latest kernel is working just fine on the HavocOS GSI ROM. Though I will be switching to a different Pie ROM shortly as HavocOS is pretty outdated now and the team is going on hiatus for a while.

Thank you for all or your hard work, as it's greatly appreciated! I'll get a donation sent out shortly after the holidays.

I didn't encounter any reboots until now ??. I recall a few times the device might have reacted a little slow when switching on the screen - nothing that I consider a serious issue though.

Great work - please keep it up. As said, your kernel made LineageOS useable again! ✌?

    Neutrino Kernel began as an effort to keep the stock LineageOS 15.1 kernel up-to-date with the latest linux-stable releases and has since evolved into an intensive crash course in maintaining my own custom kernel. Although some of you would accuse me of modesty, I think it's important to acknowledge that I am a "kernel developer" in the same way that Amy Schumer is a "comedian". That is to say, my work is highly derivative and built on the backs of individuals who are far more talented than I am. My role here is to have a vision, establish a design philosophy, and use the resources at my disposal to bring that vision to fruition.

    Those of you who've perused my staging repo will know that I'm very particular about cleanliness. All changes and additions are vetted based on viability and purpose. Neutrino is based on kernel.lnx.4.4.r35-rel, pure CAF source for Android 9.0 tracking and upstreamed to the latest linux-stable release. I have manually rebased Essential's stock kernel source on top of CAF using relevant OEM commits from PPR1.181005.034. All major features and patchsets are assembled on independent staging branches of this codebase base and merged into the release repository.

    I do not commit changes that I cannot justify or explain, and I do not go on indiscriminate cherry-picking sprees. There are a handful of developers that I highly respect, and who's projects have served as inspiration for my own. My intention is to incorporate the best of what they've brought to the table in a way that most effectively achieves and enhances this project's design goals.

    I like to think that Neutrino is relatively subdued in terms of "features", with a stronger focus on optimizations over fluff. That being said, there have been quite a few additions which I feel have merit in terms of increased performance and/or efficiency provided the former does not compromise the later:

    • Revamped EAS implementation for Pie
    • sultanxda's CPU/GPU Boost Drivers
    • Dynamic SchedTune Boosting
    • Maple I/O Scheduler
    • Broader subsystem support for Power Efficient Workqueues
    • KCAL Color Control
    • Backlight Dimmer
    • Fsync Toggle (enabled by default)
    • GPU Underclock @ 180 MHz
    • CPU (partial) Overclock, Silver Cores @ 2035 MHz
    • Boeffla Wakelock Blocker v1.1.0
    • Wireguard Support
    • VDSO Support
    • Treewide memory allocation/overflow patches from mainline
    • OOM Reaper and various memory management enhancements to improve LMK
    • Treewide compiler warnings corrected
    • Built with self-compiled Clang 8.0.3 and GCC 8.2.0 toolchains, with a local initialization sanitizer and polly optimization flags

    INSTALLATION:
    **Neutrino now utilizes AnyKernel2 zip format for universal compatibility**
    As a result, you can now flash this kernel on just about anything including Oreo/Pie custom and stock ROMs. The only requirement is that your firmware is current and up-to-date with PPR1.180905.036 at a minimum. Flashing on older firmware will result in broken input detection and a non-functional touchscreen.

    That being said, this is an EAS kernel and is best suited for use on EAS-compatible ROMs. Just because it can be flashed on stock does not mean that you should do so. Installation on ROMs which do not natively support EAS (such as stock) will likely result in sub-optimal battery performance and I will not entertain any complaints stemming from the use of Neutrino on ROMs which are incompatible with EAS. Stock support is a perk and an experiment on my part, please do not make me regret giving you the ability to flash on stock, I will drop public support for it if this disclaimer is routinely ignored. If you choose not to heed my recommendations, you are doing so at your own discretion.

    For ease of use, I would recommend using an app with built-in zip flashing functionality such as EX Kernel Manager or FK Kernel Manager. Of course, I cannot expect all of you to utilize a paid app for installation and as such, conventional installation via TWRP is certainly possible as well.

    Neutrino will preserve existing Magisk installation during kernel update, meaning if you already have Magisk installed on your device you need not worry about reflashing Magisk when updating your kernel. If you do not already have Magisk installed and desire root access then Magisk zip must be flashed following kernel zip via TWRP.

    For the sake of courtesy to anyone who still cares, I will be requesting the closure of this thread. This does not mean I am effectively throwing in the towel on this project, it's just indicative of the fact that I have run up against a wall which I am currently unable to overcome on my own accord. It seems I am currently the only person on the entirety of the internet trying to implement EAS on the new CAF Pie tags, and my individual attempts have had embarrassing results to say the least. I have no desire to maintain an HMP based kernel as there is very little that I'd be able to offer on that end that you wouldn't be able to find elsewhere, by someone more talented than I am. With that being said, until I get smarter, or find a like minded collaborator I see no reason to keep this thread open for the time being and passively stoke expectations for a future release that is unlikely to materialize in any sort of timely manner.

    So, I pretty much spent all day getting back to the point I was at yesterday but such is life. On a positive note I've rebased OEM source on kernel.lnx.4.4.r34-rel (our new CAF branch for 9.0), and upstreamed to 4.4.152. It was a slog considering there was no android-linux-stable repo to work off of this time, but it was good exercise to go through the process myself and I'm extremely pleased with how clean the result turned out to be. Really looking forward to seeing how this progresses, apologies in advance for the delay that ensues, but I promise I'm working as quick as I possibly can (just ask the last 8 hours of my life). If you're at all interested, you can follow the progress here.

    With all do respect guys, I requested this thread be reopened in preparation for new releases. I was hoping that it would silently remain unbumped until I was ready to update it but it seems that ship has sailed.

    Yes, there is a new build and I will be continuing work on this project. Some of you may very well already be running it, but there are a few things I need to take care of before it hits XDA officially and more importantly there is some pertinent information that I need to make clear in the OP in an attempt to mitigate future headaches. I will attempt to summarize some of these points for the times being..

    - New builds will be in AnyKernel zip format

    - They will run on anything including stock and oreo/pie custom ROMs provided that your firmware is up to date with PPR1.180905.036 (September) or newer.

    - Just because it runs on stock does not mean that you should flash it. This is an EAS kernel and is best suited for use with EAS compatible ROMs, I will not entertain complaints stemming from the use of Neutrino on stock or any other ROM that does not natively support EAS.

    - If you choose to flash Neutrino on stock YMMV and you are doing so at your own discretion. Stock/universal support is a perk and an experiment on my part. Do not make me regret giving you the ability to flash on stock, I will drop public support for it like a hot potato.

    That's more or less the gist of it, I'm going to take the next day or two to get a few things in order at which point I will update this thread and officially drop the new release. Thank you for your patience.
