MUST CLEAN FLASH ROM THEN FLASH KERNEL TO PREVENT LAGGINESS
Philosophy
I just wanted to start off with the goal of my kernel. Illyrian Kernel which is based off of draco kernel isn't a feature-rich kernel, nor is it a performance-bias or power-bias kernel. Illyrian Kernel includes a collection of innovative commits, designed to improve the efficiency of the device. Ideally, I will keep Illyrian kernel up-to-date.
Problems?

Upstreaming?
Has been upstreamed to the latest v4.14.183 linux kernel stable
Basic Features
Code:
- Minimal debugging and tracing
- No messy upstreams / backports that might cause issues down the line
- Latency focused
- Anxiety I/O scheduler
- Scheduler tweaks and hacks
- CPU governor adjustments
- ZERO in-kernel boosting while maintaining a smooth userspace
Advanced Features
This is just from the first official beta, so this list may change in the future.
Code:
- Remove AVB checks
- Disable SECCOMP (faster syscalls)
- Disable Audit (expensive in Android)
- Use non-blocking random pool
- Target small cluster in Makefile
- Disable IRQ debugging
- Don't use high-priority workqueue for usb policy_engine
- Disable profiling (kdrag0n)
- Anxiety I/O scheduler (sync read priority)
- Schedule last-woken task for better cache locality
- Reduce cache pressure to keep cache valid for longer
- Increase vmstat interval to reduce intermittent jitter
- Adjust dirty ratios to writeback dirty pages later rather than sooner
- Do not collect I/O stats from block subsystem
- Don't dump oom_killed tasks
- Do not use UFS for randomness
- Disable ASLR fully by default (performance not benchmarked)
- Disable JTAG debugging by default
- Inform kcompact of fragmentation moreso than full RAM usage
- Do not compile HIGHMEM (unused by our system)
- Awaken kswapd at 1% (80mb free left) instead of 0.1% (8mb free left)
- Do not compile watchdog (reduces jitter)
- BFP JIT (better networking performance)
- Force block requests to execute on their origin cpu (better cache locality)
- Increase haptic strength
- Allow GPU to sleep / nap
- Do not compile zRAM (unnecessary for this kernels MM settings)
- Do not perform readahead (proven to improve power and performance by 70%)
- Align scheduler timeslices with jiffies
- Overcommit memory for faster Android start times
- Remove a bunch of debug and tracing that is unnecessary for the kernel
- Remove schedutil hispeed boosting
- Remove iowait boosting (saves a large amount of battery)
- Do not expedite RCU
- Halve round-robin timeslices
- Expedite wakelock garbage collection
- Lower I/O request limit for lower latency
- More that I forgot
