Proton Kernel Features

Full support for both Android 9 and 10
Unparalleled fluidity thanks to:
- Deep scheduler optimizations
- Optional 72 Hz screen refresh rate
- Ultra-low jitter between 0.12 and 0.3 milliseconds (as compared to stock's range of 1.75 to 2.5 ms)
- Static SchedTune boosting and idle CPU preference
- CPU affinities tuned specifically for the Snapdragon 855 CPU
- PELT load tracking with an 8 ms half-life and Android Common Kernel updates
- Memory bus boosting (using Sultan's devfreq boost driver)
- Accurate, measured CPU performance capacities in the EAS energy model
- Reduced unncessary frequent dynamic memory allocations (Sultan, arter97)
- Master GPU dispatcher thread with high priority (Sultan)
- Improved Prime cluster utilization
Efficient memory utilization enabled by:
- Sultan's Simple Low Memory Killer
- Reduced memory leaks
- Disabled the CPU-hogging zRAM swap present on stock
Faster network speeds as a result of:
- A more advanced scheduler (fq_codel) renowned for its bufferbloat management capabilities
- Westwood+ TCP congestion control algorithm
- Retention of Qualcomm's stock RmNet extensions to boost cellular data speeds
Magisk preservation
- No need to re-flash Magisk after kernel installs and updates
Low-level driver optimizations for better overall performance:
- Sultan's IOMMU and ION overhauls that especially help video playback and recording
Built on a rock-solid foundation for enhanced security and stability
- Based on the latest Qualcomm CAF sources
- Latest mainline LTS updates merged
- Minimal Asus changes
Faster and more reliable storage
- Latest F2FS fixes and improvements from mainline (f2fs-stable)
- arter97's Rapid GC for improved long-term performance
- Optimized hot/cold file extension lists for performance and flash longevity (thanks to arter97)
Widespread bug fixes from:
- Qualcomm's code for the Snapdragon X55 5G mode
- Mainline LTS updates
Compiled with state-of-the-art tools
- Specialized toolchain built from bleeding-edge LLVM + Clang 10 sources
- LLVM integrated assembler
- LLD linker
- LLVM replacements for the objcopy, nm, ar, and objdump tools
A plethora of power-user features
- Namespaces to support lightweight containers
- System V IPC
- POSIX message queues
- High-resolution battery level exportation
- WireGuard VPN support
Strong security
- Insecure SELinux auditing removed
- Fixes for unsafe uninitialized memory usage
- Unnecessary debugging features and modem diagnostics disabled
- Support for the USB device lockdown setting in LineageOS Trust
Speedy, customized kernel flasher
- Based on the proven AnyKernel3 template by osm0sis
- More verbose and concise messages in a user-friendly format
- Tuned for faster flashing
- Ramdisk passthrough for improved compatibility with ramdisk modifications
Lean size (11 MB) for:
- Faster downloads
- Reduced boot times
- Reduced internal overhead in some areas
Strong core philosophies
- Transparency
- Open development
- Performance & fluidity without significant battery compromises
Empirical data-driven development
- Using a variety of low-level benchmarks, many of which are available in my Benchkit Magisk module
- Constant system monitoring that leverages professional DevOps tools: InfluxDB and Grafana
- Restored CPU frequency stat accounting (disabled out-of-the-box by Qualcomm)
Additional miscellaneous improvements
- Minimal debugging for increased performance and reduced kernel size
- Optimized reference counting implementation backported from the mainline ARM kernel mailing list (patch)
- Improved BBR TCP congestion control algorithm thanks to arter97's mainline backports
- Profile-based internal driver micro-optimizations
- 32-bit vDSO to accelerate 32-bit applications
- Support for overriding network TTL to bypass hotspot detection on some carriers
- exFAT support using Samsung's sdFAT driver (compatible with both stock and custom ROMs)
- Reduced CPU frequency stat accounting overhead
- Backported faster queued spinlock implementation from mainline
- Backported atomic operation, read-write semaphore, and mutex optimizations from mainline
- Warm resets to preserve kernel logs across reboots
