Announcement from eng.stk: blu_spark r38 unified is up!

Kernel features:
  • Powered by Ubuntu 16.04.6 x86_64 (sparky VPS @ www.servercore.com.br - thanks @ChristianLetti)
  • Build with custom toolchain blu_gcc-9.2.0 (cortex-a76.cortex-a55 targeted, build with latest Crosstool-NG from GCC-9.2.0 snapshot)
  • Full -O2 build with device and target flags enhanced, linaro build improvements, etc
  • Less is more: stockish OP7 builds based on OnePlusOSS/android_kernel_oneplus_sm8150 for max stability
  • Systemless installer (doesn't touch system partition, OTA friendly), AnyKernel3 backend (compatible with autoflash apps)
  • Removed some debug and logging options
  • ARM enhanced performance and battery patches
  • CVE security patches, general upstream and CAF fixes for important subsystems
  • Several CPU Governors (blu_schedutil modded governor merged from latest CAF sm8150 patchset)
  • No OC, use 300HZ base timer frequency
  • msm_performance touchboost toggle on/off (enabled by default), tweaked cpu_boost driver
  • Enhanced TCP methods (westwood is default), Network tweaks and updated drivers
  • Several I/O control tweaks, added schedulers ZEN v2 is default, advanced filesystems enabled (F2FS, ExFAT, NTFS, CIFS & NFS)
  • Patched SafetyNet flags to pass CTS
  • Stock thermal driver by default
  • ZRAM Swap (LZ4) and with file disabled
  • Vibrator Strength tunable and Gesture Haptic Feedback control (touchpanel and FPR)
  • KGSL fixes and reworked GPU driver
  • adrenoboost enabled by default at low level
  • KCAL - Advanced color control for Qualcomm MDSS v2 (RGB calibration and post-processing features)
  • KLAPSE support (v5.0)
  • USB Fast Charge (USB mode up to 900mA with MTP on)
  • FS fsync toggle on/off
  • Wakelock blockers available
  • wireguard support
  • CDROM emulation on mass_storage (compatible with DriveDroid 0.10.36+)
  • Compatible with Kernel Adiutor, EXKM, FKM and others


(No mirrors please)


Warning: If you come from other kernel or have any issues, you should dirty flash your ROM before flashing blu_spark zip to avoid problems.
Reflash ROM -> flash TWRP --> reboot to recovery --> flash Magisk if you want (default, no plugins/modules) -> flash blu_spark.
If you are already rooted or upgrading between blu_spark versions, just flash the kernel zip. 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). That includes NO support if using xposed, Magisk with modules, etc.
If you're using custom ROMs (including OOS based ones) or Open Betas you're on your own. I'm only interested on debugging stuff in stock and stable 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, Recovery/TWRP troubleshoots and other userspace stuff. There's threads for it, use them.

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

Info 2 blu_spark r10 release (unified)
All right crew!

New build is up
This kernel is unified, should be good on OP7/Pro (I only can test on Pro).
So keep this in mind if there's anything wonky. Check out the 7 Pro thread, some stuff is already discussed there.


blu_spark_r10 release

Quote:

  • KCAL v2
  • KLAPSE v5.0
  • adrenoboost
  • USB2 fast charge (if it doesn't work, restart the device without any cable, turn on fast charge and connect the cable after)
  • couple init settings tune
  • AnyKernel3 updates


Keep in mind: I will give no active support for custom ROMs (including OOS based ones).
I am only interested on debugging stuff in stock and stable OOS (with logs and reproducible steps to replicate the issue).
Don't spam this thread with LOS 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.

Yes, all good! "Battery life" and performance are great. Zero heat up while playing heavy games. Keep up the good work!

Has the kernel something todo with the signal strength/mechanism of a device or is this a rom setting?

Depends strength of what in particular?
If you're talking about 4g/gsm, nope.
