• Built with GCC + Graphite + LTO + PGO
• Built-in kernel modules for better optimization with LTO
• Backport upstream Multi-gen LRU to optimize page reclaim and performance under memory pressure
• Backport entire RCU subsystem to Linux 6.0
• Lazy RCU which should result in power-savings while the device is lightly-loaded or idling
• Backport EEVDF Scheduler (Earliest Eligible Virtual Deadline First) in favor of CFS
• Disable unused touchscreen and keyboard drivers
• Disable tracing, statistics and various debugs
• Use power efficient workqueues
• Relax kernel wakelocks
• Backport upstream mremap
• Allocate small objects on stack instead of heap to reduce overhead
• Import latest version of Cortex strings' functions
• Disable kernel hardening for faster syscall performance
