Implement fws-gameboot, an orchestrator for seamless dual-boot between FWS and Windows
bare-metal using hibernate-swap mechanism. Enables playing kernel anticheat games
(e.g., Valorant/Vanguard) without persistent virtualization by hibernating FWS
to swap, setting BootNext to Windows UEFI one-shot, and rebooting. Upon Windows
shutdown, the kernel resumes the FWS session via resume= parameter.
Features:
- doctor/status subcommand: validates hibernation readiness (swap size, resume=
parameter, VRAM usage, Secure Boot status)
- to-windows subcommand: hibernates FWS, unmounts NTFS filesystems, arms BootNext,
and initiates hibernation; resumes FWS session on return from Windows
- Safety mechanisms: BootOrder[0] fallback to FWS via fws-gameboot-bootfix,
permanent BootNext cleanup on resume, optional simple reboot fallback
- Configuration via /etc/fws/gameboot.conf (Windows boot entry number, swap margin,
hibernation fallback mode)
- User notification via D-Bus notify-send for graphical feedback
- Comprehensive error handling and preflight validation
Requires validated hardware support for NVIDIA GPU hibernation/resume and firmware
BootNext semantics.
