The next generation Toddler
Major Goals
- Written in C99
- Unified boot protocol for all architectures with Device Tree support, combined with ACPI on x86 and OFW on PPC/SPARC
- Support more architectures (ARM, PowerPC, x86, RISC-V, Alpha, SPARC, m68k) and machines (e.g., Multiple ARM boards)
- More efficient IPC
- Refined kernel APIs
- Refined VFS and user model
- Complete standard C library
- Console, shell, and utilities
- Run on QEMU and other emulators
- Run on real machines
Long-term Goals
- NetBSD as an environment system
- X11
- Package management system
Misc.
- Fix up SMP support
- x86: replace NASM assmebly with GAS on x86 and multiboot compliant
- More architectures - OpenRISC, HPPA, SuperH, IA64, s390, VAX
