Kernel features:
  • Powered by Ubuntu 16.04.1 x86_64 (sparky VPS @ www.servercore.com.br - thanks @ChristianLetti)
  • Build with custom toolchain blu_naro-6.3 (cortex-a53 targeted, build with latest Crosstool-NG from developer snapshot Linaro GCC 6.3-2017.01)
  • Full -O3 support with device and target flags enhanced, linaro build improvements, etc
  • Less is more: stockish OP3/OP3T unified builds based on OnePlusOSS/android_kernel_oneplus_msm8996
  • Systemless installer (OTA friendly)
  • Removed some debug and logging options
  • ARM enhanced performance and battery patches
  • General upstream and CAF fixes
  • Several CPU Governors (blu_active own upstreamed and tweaked governor by default)
  • Overclock available (boots with default freqs), set 300HZ base timer frequency [soon]
  • msm_performace input boost toggle on/off (disabled by default), tweaked cpu_boost driver
  • Enhanced TCP methods (westwood is default), Network and Wifi tweaks and updated drivers
  • Several I/O control tweaks, added schedulers FIOPS and ZEN v2 is default, tweaked filesystems (F2FS upstream, ExFAT, NTFS & CIFS)
  • Removed verify and forced encryption
  • Stock thermal driver by default (custom tunables available)
  • Optimized RWSEM, AES and SHA1 routines (with NEON support)
  • Swap and adaptive LMK off by default
  • Vibrator Strength tunable and Gesture Haptic Feedback control
  • KGSL fixes and reworked GPU driver (use 133MHz min freq to save juice, goes to idle @ 100MHz)
  • sRGB and KCAL - Advanced color control for Qualcomm MDSS v2 (RGB calibration and post-processing features)
  • DASH charge and USB Fast Charge (USB mode up to 900mA with MTP on)
  • Battery/Notification LED control
  • Multimount fstab (you can use data f2fs or ext4)
  • FS fsync toggle on/off
  • CDROM emulation on mass_storage (compatible with DriveDroid 0.10.18+)

  • Compatible with Kernel Adiutor Beta and others

DOWNLOAD KERNEL ZIP


Warning: If you come from other kernel, you should dirty flash your ROM before flashing blu_sp★rk zip to avoid problems.
Reflash ROM -> flash SuperSU -> flash blu_sp★rk.
Also uninstall or clean data of any kernel control app you're using.

About bugs and troubleshoots: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. I only active support stock OOS with NO mods whatsoever (apart from root). If you're using custom ROMs you're on your own, I'm only interested on debugging stuff in OOS.
Save the SOT and battery stats/screenshots for general threads, here we deal with development, not personal tastes and results.
Also don't spam this thread with CM or other ROMs stuff like "this don't work, my app doesn't open, etc" , no OT about OTAs, apps, ROM bugs and other userspace stuff. There's threads for it, use them.

Going back to stock: This kernel installer doesn't change your filesystem (systemless).
You can backup your boot.img with TWRP before flashing blu_spark if you want to go back to full stock or just flash sotck boot.img / dirty flash your full ROM.


Advanced filesystem: If you want to use EXT4 instead of F2FS, do the following (backup your data to external source before attempt this, it will erase all your sdcard data)
  • Flash TWRP and latest blu_sp★rk zip
  • Go to Wipe -> Advanced Wipe -> Select only Data -> Repair/Format File system -> Change partition type to EXT4
  • Go to Wipe -> Advanced Wipe -> Select only Cache -> Repair/Format File system -> Change partition type to EXT4
  • Reboot and profit
To be back on F2FS, just do the same but choose F2FS instead

All right crew!

New build is up. Wicked!

I decided to bring this kernel form the OnePlus 3 to the 3T :victory:
From those of you that already know me from Nexus, Motorola and other Oneplus devices you know what to expect: stability, useful addins, original work and features, no cruft, lean optimizations, security updates, better battery / (real life) performance, better overall UX.
Enjoy!

  • First build for 3T, fully synced with 3 branch
  • Add Disable Gesture Haptic Feedback control json (unzip the attachment and import in Kernel Adiutor Custom Control tab, hit "+" and import)


Keep in mind: I will give no active support for custom ROMs or OB. Meaning, if using anything besides stable OOS don't bother posting about it.
I am only interested on debugging stuff in stable OOS (with logs and reproducible steps to replicate the issue).
Don't spam this thread with CM or other ROMs stuff like "this don't work, my app doesn't open, etc" or debugging features.
Also don't go spam and bug reporting on ROM threads if using this.

@eng.stk Great to see you here! I've been enjoying your op3 kernel very much.

Advanced filesystem: If you want to use F2FS, do the following (backup your data to external source before attempt this, it will erase all your sdcard data)
  • Flash TWRP and latest blu_sp★rk zip
  • Go to Wipe -> Advanced Wipe -> Select only Data -> Repair/Format File system -> Change partition type to F2FS
  • Go to Wipe -> Advanced Wipe -> Select only Cache -> Repair/Format File system -> Change partition type to F2FS
  • Reboot and profit

Is this just copy/paste from your op3 thread or do we really need to wipe data to use f2fs? Thought it's the stock filesystem on the op3t.

I'm wanting to know the same thing, but looking forward to flashing it later today.

Good to see you here buddy, thank you for your continued support :)
Thank my wife, because Oneplus didn't gave me anything despite the huge amount of work I did on the OPX/OP3.
Seems like I don't fit on the "popstar" developer selection, so no device given to me to develop on.
I never monetized my work and I will continue to do so: I prefer to be a rock'n'rolla :)

Yeah it was a typo, no need to format, just flash the zip

@eng.stk : Welcome and a quick question (I hope):

I'm guessing that you create custom modules (/system/lib/modules/*.ko) for your kernel. If so, I'm wondering if it's really possible to revert back to stock kernel , the way many people are claiming it is, by just flashing the old 3.5.3 stock boot.img file? I've not yet developed for Marshmallow, only earlier flavors, so I'm still of the ilk where it mattered what modules were in /system/lib/modules, not just what was in the ramdisk in boot.img.

Can you shut me up for good on this topic with a good answer? (I'm about to shut up anyway lol).

Thanks and thanks for the new kernel.

When I have the original kernel do I have to flash also the dirty ROM?
No, if you are all stock just flash the the kernel zip (you need to have bootloader unlocked and flashed twrp ofc)
If I understood the question correctly...

Sure that's what systemless is: I don't touch the system partition.
Flashing boot.img from 3.5.3 get's you full stock again.

    • Rebase and merge OnePlus N changes
    • Up to 95% features in
    • Custom build for N ROMs and TWRP will be updated later
