In the latest version I'm experiment an abnormal overheating. Even when I do simple tasks like see videos in YouTube, using chrome, Tapatalk, Spotify, etc.

Check sync threshold, I set it to 1036 and its fine

Also input boost 1574 on core 1 and core 3

The rest disabled

Hey Omar, I had a forced reboot using v37 with stock CM14.1 Was using the music app and tried turning on the screen with a double tap, then got a reboot. I made a logcat for you, sending the link to your private msg.

Thanks! I will try that config. In kernel adiutor the CPU usage it's of 99%(at 1190 MHz), but I don't do anything and I can't find the reason...

My god latest version has been the most smooth since v31.
Edit: nvm. Lots of microstutters but getting better. Back to v31

DESCRIPTION
This is a custom based Kernel for the D855/D852/D851/D850 variants of the LG G3 with performance enhancements and bug fixes that I have been using personally for a few months, thought it is time to share since I have had no inconvenient bugs and quite a big performance increase and smooth UI benefits. The intention is to have a minimal light-weight kernel that is fine tuned for the device.

FEATURES

  • User space voltage control
  • Backport MSM devfreq features from 3.10 Kernel for the smoothest experience, includes adding cache fabric frequency scaling and better bus utilization
  • User space display color calibration (KCAL)
  • Deeper memory controller power savings on suspend (deeper power savings while sleep)
  • Two new L2 cache frequency steps: 1.88 & 2.03 GHz, allows for better multi-core utilization and hit rates
  • Wireless roaming disconnecting is now fixed
  • MPDecision argument optimization to allow lower thermal dissipation by keeping some cores alive to distribute loads and keep frequencies lower accross SoC die
  • Reduced heat when using wireless chargers
  • Memory and cache subsystem optimizations, you will feel it int the UI
  • Adreno Idler to get better GPU frequency utilization and battery life [removed as msm-adreno now idles properly]
  • Interactive governor tweaks to focus on lower frequencies while still maintaining fluidity in the UI
  • BFQ IO scheduler set by default to avoid slow-downs on task intensive scenarios
  • No overclocking was chosen to avoid unnecessary heat, optimizations were focused on other different areas
  • Small lock and dentry cache optimizations from 3.4.107 backported
  • Kernel Samepage Sharing enabled with deferred timer by default to gain some memory usage optimizations
  • Compiled with GCC 6.x optimized toolchain and -O3 plus other hardware specific flags
  • Undervolted the Adreno 330 GPU voltage rail to keep things cooler, and reduced the GPU min frequency to 27 MHz while keeping it's temperature cool to reach 620 MHz overclock
  • Default thermal values work ok, since GPU voltage rails and others were shaved a few mV
  • 100 Hz tick to prevent excessive battery usage, the smoothness of the UX does not come alone from raw processing -- there are many other changes in the subsystem that helped achieve the fluidity
  • A low value in the min_sample_time so that the interactive governor does not hover on excessive frequencies
  • Heavily tuned the GPU bandwidth and bus requirements to match closer the capabilities of the device and thus preventing micro-stutters
