Architecture Ports

How the kernel is meant to grow beyond x86-64: an abstraction layer that separates architecture code from the rest, a 64-bit ARM port, and support for machines with more than 16 processors. The kernel runs on x86-64 with up to 16 CPUs today, and none of these roadmaps has started; each page says what exists now and which roadmap section owns the rest.

Planned

One page per roadmap file, each following the page contract.

Document	Topics
Architecture Abstraction Layer	HAL header, `src/kernel/arch/` split, `ARCH=` build variable; where the x86-64 code lives today
AArch64 Kernel Port	`BOOTAA64.EFI`, GICv3, generic timer, PSCI, `SVC`, NEON and SVE, PAN, BTI, PAC and MTE
SMP Scaling and Processor Groups	The 16-CPU limit, MADT parsing, processor groups, `KeSetTargetProcessorDpcEx`, group affinity

Longer-range research on the same subjects is in Future Research.
