I don't game much at all so I can't give a good timeframe myself. I don't see any major performance issues other than an occasional stutter where I feel like there shouldn't be. My wife, on the other hand, occasionally sees performance issues due to throttling after playing her "tapping" games or snapchatting, as others have mentioned. The Anandtech 5x review gives a fairly detailed assessment of the thermal behavior and states the big cores throttle to 633Mhz after 2 min and then shut off completely after 12. I'd say that probably lines up with some of the behavior my wife is seeing.

It's interesting to me that you don't see this aggressive throttling on other 808 based devices like the G4 or moto x pure. This gives me hope that it can be fixed on the 5X.

To be honest this smells like typical LG bull****. I'll see what I can do.

Well, the "fix" is easy. cpu4 and cpu5 go offline when the battery temp reaches ~31ºC. If we disable core_control on the thermal driver, they won't go offline, ever, but they'll stay throttled to their lowest cpu frequency. Then the little cluster won't start throttling until the sensor reports 70ºC on the cpus (not battery), and they basically stay at 960MHz indefinitely if the CPU temp stays hovering around ~65ºC. The device is a bit warm to touch, but not that much. I can almost safely assume we can disable core_control without any damage prevent major performance hit.

I'm so impressed with how smooth the scrolling is. On tapatalk i can't get it to microstutter as hard as i try. Awesome release for the 1ST OFFICIAL franco.Kernel. The app seems to be running great for the 15 minutes I've had 14.0.2 installed but again I'm new to this app & kernel but looks like it's a winner. Thanks again for purchasing the N5X and bringing your talents to all of us.

Dang you've convinced me to move off of CM13 until the ramdisk stuff gets resolved. I used your kernel on my Nexus 5 and dang... i'd come home from school with 80% battery

r1 officially out. I didn't have time to add sound control, but will do it for r2 - I'd rather get this out instead of delaying since I'm pretty happy with it. Flash this final r1 if you were using the WIP version.

Flashing supersu systemless 2.66 after the official r1 leads to an error. Flashed on top of the wip build. Downloaded it twice, same thing happened.

Edit: tried flashing the boot.img instead of the zip. Then supersu 2.66. Successfully flashed but stuck forever at Google logo. :confused:

Going back to wip for now

I think I know the problem. SuperSU creates a backup before patching the kernel. I think you need to delete the backup first and then flash Franco, then SuperSU again.

The backup is located at /data/stock_boot<long string>.img.gz

Works for me.

P. S. Does that mean that we have to do this every time new Franco kernel comes out?

I see you've disabled ZRAM.

What more is done to minimise lag? Will disabling ZRAM make te device perform more consistently over a period of time? That's my main gripe with this device, performance after a while.

I'll look forward to seeing how the kernel performs in a week. Things are smooth as of now. Didn't like the colour tweaks though, set those back to default.

    Hi all.

    Compatibility:
    It should work on any rom by following this logic:
    Builds (starting with r1) are Android 6.0.1 Marshmallow only.
    Builds (starting with r17) are Android 7.0 Nougat only.
    Builds (starting with r28 up to r37) are Android 7.1.1 Nougat only.
    Builds from r38 up to r44 are for Android 7.1.2 Nougat
    Builds from r45 up to r48 are for Android 8.0.0 Oreo.
    Builds from r49 are for Android 8.1.0 Oreo.

    Download:
    https://francokernel.app

    Installation:
    Flash the zip in your recovery
    or
    Auto-flash from Franco Kernel Updater app

    Features:
    1 - Legendary battery life
    2 - Flash & forget
    3 - Typical interfaces like display adjustments, sound control, vibration control, and all that boring stuff
    4 - Bypasses the verified boot flag for Android Pay compatibility (root still breaks Android Pay but that's your own problem)
    5 - Idle power consumption reduced to the absolute minimum (if you have wakelocks from 3rd party apps you're obviously on your own)
    6 - Support for FKUpdater's Performance Profiles
    7 - Magical support, I'm here every day, checking posts almost hourly, ready to help anytime (well, unless you fail to read the OP, which contains most info you need)
    8 - Seemless integration with my app FKUpdater
    9 - No crap placebo patches, or "magical" optimizations
    10 - Probably more, check my github for all the details - the code speaks for itself

    Kernel Manager for Franco Kernel demo

    Disclaimer to moderators:
    Slight OT is fine, but when users decide to act stupid they should be dealt with with the appropriate means - its really annoying for me when OT turns crazy. Please put the warning/ban hammer anytime any of you think there's lack of respect and/or too much unwanted OT crap - but if it doesn't meet this criteria let the OT posts alone. Thank you.

    Cheers!

    Current r1 is not yet complete, I think it only lacks sound control, but it's pretty much done.
    Took me a little while to find the right balance, this little bastard lags easily, but this Kernel is pretty much a "clone" of FK for the 6P so I'm sure you'll have some fun with improved battery life.

    FKUpdater will be updated tomorrow to support this Kernel and the final r1 release will also be out.
    Any feedback about UI responsiveness and anything else that comes to mind, now's your chance to talk.

    Two things to note though, EIS video stabilisation is enabled automatically with FK, just check your Camera app and you'll see it, and FK ships with a slightly cooler display colour temperature, and a very slight saturation boost.

    I wasn't supposed to work on this device because I didn't want to shell out 450 euros for a device I wouldn't use outside Kernel/app development, but in the end I did it for you.

    Enjoy it & you're ducking welcome.

    New Franco Kernel version for the Nexus 5X

    r35
    1. Offload a lot of background daemons to the system-background group, which only allows them to run on cpus 0, 1 and 2, freeing all other cores, specially the big cluster. This will reduce needlessly cpu wake-ups from idle, and largely reduce processing power requirements from cpu 3, 4, and 5 (4 and 5 are part of the big cluster, which uses a lot of energy)
    2. Lower power consumption from the big cluster by lowering the occurence of sample rate which'll in turn make the big cluster cpus less nervous and say in lower frequencies more often. In contrast little cluster is a little more forgiving and scales up a little easily. Since the little cluster uses 4 times less power, this is just fine
    3. Tweaked Performance Profiles, Power-saving now turns off the big cluster to save precious power, but the little cluster will be boosted for longer during input touch events

    zip: https://kernels.franco-lnx.net/Nexus5X/7.1/anyKernel/fk-r35-anykernel2.zip

    Franco Kernel Manager & Updater is the best companion for this Kernel (https://play.google.com/store/apps/details?id=com.franco.kernel)

    If you don't (yet) have my full featured app you can always just download its free counter part which lets you seamlessly and automagically update Franco Kernel on your device. It's free and my cat approves! (https://play.google.com/store/apps/details?id=com.franco.kernel.free)

    I also strongly suggest you install Naptime (https://play.google.com/store/apps/details?id=com.franco.doze), for free, to achieve the best battery life through out the day. Try it, you won't be disappointed!

    Alright r46 is out. Rebuilt everything from scratch like I should've done in the first place. Everything should be fine now. Sorry for the delay, been busy with lots of things and rebuilding the entire tree on top of the vanilla sources is just tiresome and a pretty long process.
    You can auto-flash it with my app http://get.franciscofranco.xyz or manually through the links in the OP.

    Ok similar to what I've been doing to the 6P, 6 and 5, we are now able to flash r5 onwards on any available rom. This is not yet available through FKUpdater (it needs an update, working on it), but you can download it from my server and play with it. Instructions below and in the OP:

    Download:
    Flash the latest release in your recovery:
    http://kernels.franco-lnx.net/Nexus5X/6.0/anyKernel/
    If you're already on r5, or newer, disregard the messages below - if not:
    * If you're on stock rom + r4, or older, you should be flashing stock boot.img first, then r5, or newer;
    * If you're on a custom rom + r4, or older, you should dirty flash the rom (or extract its boot.img and fastboot flash it) and then r5, or newer;

    Installation:
    1 - Flash the bloody zip on your recovery

    As for the changes compared to r4 I added more ways to prevent memory starvation, reduced power consumption during screen off and other security related patches.

    You're ducking welcome.
