CYFARE Kernel Optimize V2.0 (Debian-only edition)

• Latest Linux Kernel (Update Supported Series!)
• BORE scheduler + CachyOS performance patches (with aggressive multi-source fallback), builds with Clang/LTO/per-CPU tuning, packages as .deb, and installs it on Debian/Ubuntu/Mint/MX/Pop!_OS/Kali and every other Debian-based distribution.
• Default released packages use: All Patches + BORE + Full-LTO + x86-64-v3

This edition:

• Is Debian/apt only — no RPM/pacman/zypper/apk/emerge paths.
• Performs smart detection of CPU ISA level, RAM, cores, GPU, disk type, and boot loader, and picks aggressive-but-safe defaults tuned for a responsive gaming/desktop machine.
• Uses the BORE scheduler + CachyOS patchset pipeline with all the hardening (olddefconfig under the same toolchain, patch fuzz tolerance, auto-series fallback, BORE verification, etc.).

Requires: PyQt6 (apt: python3-pyqt6 ; pip: PyQt6) All build dependencies are installed automatically via apt on first run.

changelog

• Parallel builds actually use multiple cores now. Removed --output-sync=line from compile/package commands; switched make subprocesses to buffered stdout and close_fds=False so GNU make's jobserver FIFO stays open to sub-makes and writers don't block on a full pipe.
• Respect CPU affinity/container limits. Added _available_cpus() using os.sched_getaffinity(0) / os.process_cpu_count() instead of os.cpu_count(). jobs default and system detection now report the CPUs the process can actually use.
• Sanitize inherited MAKEFLAGS. Strip external --output-sync, -jN, and -O... flags so a shell/CI setting can't silently serialize the build.
• Root disk detection now correctly handles NVMe (nvme0n1/nvme0n1p1) and eMMC (mmcblk0pN) devices.
• ISA level detection now accepts abm as an alias for lzcnt and bmi as an alias for bmi1, fixing under-detection on modern Intel CPUs.
• GPU detection AMD branch now has explicit parentheses for correct operator precedence.
• SCHED_BORE checkbox is now wired into BuildConfig and honored during config tuning.

Changed

• Refactored make command construction into _make_base_cmd() and _compile_env() helpers; packaging now uses the same KCFLAGS environment as compilation.
• Subprocess _run() now uses buffered I/O by default and escalates cancel from terminate() to kill() if the process ignores SIGTERM.

Internal

• Moved datetime import to the top-level.
