[KERNEL] [blu_spark r237 OP8/Pro/T] [A14 Custom]

[eng.stk]

Kernel features:

• Build with custom upstream LLVM 14.x (Clang 14.0.6 + LLD linker + IAS)
• Full -O2 build with device and target flags enhanced, build improvements and compiler fixes, etc
• Less is more: stockish OP8 builds based on LineageOS/android_kernel_oneplus_sm8250 for max stability
• Systemless installer (doesn't touch system partition, OTA friendly), AnyKernel3 backend (compatible with autoflash apps)
• Removed some debug and logging options
• CVE security patches, general upstream and CAF fixes for important subsystems
• No OC, use 250HZ base timer frequency
• msm_performance touchboost toggle on/off (enabled by default), tweaked cpu_boost driver
• Enhanced TCP methods (westwood is default, BBR available), Network tweaks and updated drivers
• Several I/O control tweaks, added schedulers ZEN v2 is default, advanced filesystems enabled (F2FS, ExFAT, NTFS, CIFS & NFS)
• ZRAM Swap (LZ4 default) and with file disabled, LZO-RLE and ZSTD are available
• Vibrator Strength tunable and Gesture Haptic Feedback control (touchpanel and FPR)
• KGSL fixes and general improvements for GPU driver
• adrenoboost ready (disabled by default)
• Backlight min brightness and backlight scale option
• Gamepad support enabled (xbox, ps4, switch)
• 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

DOWNLOAD KERNEL ZIP
FKM download configs: oos | custom
(No mirrors please)​

Setup and troubleshoot: To install just flash the zip on a stock setup with either TWRP or autoflash kernel app.
If you come from other kernel or have any issues, you should restore your stock boot.img or dirty flash your ROM before flashing blu_spark zip to avoid problems. Also uninstall or clean data of any kernel control app you're using.
If you are upgrading between blu_spark versions, just flash the kernel zip.

About bugs and reports: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. I only active support ROMs with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with added modules, etc.
Currently only LineageOS or LOS based ROMs are supported, OOS is EOL.
Also try not to spam the thread with OT. There's threads for all kind of stuff, use them.

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

blu_spark r12 release

All right crew!

It's that time again, 1st build is up :highfive:

This kernel source is unified for OP8/Pro, don't know how it will run in the regular model (can only test in the Pro). Let me know.
At the moment we're maybe at 80% of the usual goodies, get a nice and stable base and go from there.
I'm building with clang currently got some hiccups with gcc. I'll probably revisit this in the future but it will need more TLC.
You can now use FKM download kernel feature, just import the links bellow in the app :highfive:


blu_spark_r12release
FKM download configs: oos | custom

• Build with latest Google Clang version 11.0.2 (Android 11) - blu_gcc may come in the future, needs som TLC
• Synchronize codes for OnePlus 8 Oxygen OS 10.5.9.IN21AA and OnePlus 8 Pro Oxygen OS 10.5.10.IN11AA
• Build errors and warnings fixes
• Compiling improving and target optimizations
• Goodies: IO and filesystem stuff, priorities and UX, touchboost, zram, wakelock blocker, haptic and gestures level, adrenoboost, etc
• wireguard updates (v1.0.20200611)
• init adjust for sdm8250
• AnyKernel3 latest updates
• For root, stable Magisk 20.4 or newer is mandatory

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.

ur kernel is great for daily use when I have 6t, it's fast, smoot, and stable. do u plan to build one for oneplus 8?

 

[galaxys]

Great to see your blu-spark here! Kudos

 

[Surfeur-des-Reves]

Great job! Any list of the best settings to activate for your kernel in FKM? Can't manage to activate westwood TCP method, it gets stuck to reno, for example. Or any config file to have the best settings selected, maybe? Sorry, I'm not too familiar with FKM yet.

 

[tbalden]

Hey there, welcome. Nice to see you here.

Just one question, why are so many features listed in the OP and many or most not in the sources on GitHub? Isn't this a copy paste error?

At the moment I'm focused on the bringup.

I already inject settings I see importanton the background. TCP method is westwood by default, that reno situation is a bug from the app, franco is on it :good:

it's not working on regular 8

 

[akshat207]

After installing this kernel I'm getting an option to boost GPU clock to 900 MHz. This also resulted in a much higher compute score. Is this normal? @eng.stk

 

[Smturbo]

On8 not working

 

[hjjiang]

Cool to see another old kernel dev from the nexus 5 days xD

On8 not working

Hum too bad. Seems like there's driver differences between the models, we'll see what can be done ib the future.
For now I'll concentrate on the pro.

Wait, what? Seem like that app is on acid lol

Then how did I get 4351 OpenCL score on Geekbench lol?

You probably still have custom dtb from the kernel that have gpu oc, since this kernel doesn't replace the dtb and you switched kernels without keeping that in mind you ended up with mixed kernel images and dtbs.

So, how is that much GPU OC possible? that's almost double the stock max frequency!

EDIT: You were right, it was from "Evira Kernel". Now my question is, is that much OC safe? That's insane.

Do note that my device didn't get hot when I was running the benchmark even at 900 MHz.

what was the problem for the regular OnePlus 8? bootloop and what region was ur phone

At the bootloader unlock screen, after a few seconds, the text turns green and has black lines through it, when it finishes booting, by the screen goes completely black. Vibration and sound still work though. Have to force power off and back to TWRP to restore stock boot.
