FreeBSD on Power9 (ppc64) Parity

• NMI semantics: NMIs need to be emulated by only soft disabling interrupts, disabling interrupts blocks all interrupts except machine check exceptions and system resets.

• Superpage support is stable and on by default in the POWER9BSD staging branch

• NUMA support: Parse OFW and set up appropriate structures for memory to be allocated from the correct domain and interrupts to be bound to the

Bootstrapping Rust and Cargo on FreeBSD/aarch64

At the time of this writing, Rust and Cargo are available on FreeBSD/amd64 and FreeBSD/i386 only, whether it is from rustup or from the FreeBSD ports tree. Here is how I could bootstrap Rust and Cargo for FreeBSD/aarch64 from FreeBSD/amd64.

Base system for the target

To be able to cross-compile anything, you need a userland for the target.

Scaling:
FreeBSD 12 saw the introduction of a number of performance improvements:
   - the introduction of the new synchronization primitive epoch to replace the
     use of reader locks for providing existence guarantees for data structures
   - epoch was used to provide an 85+% reduction in the overhead of pcb lookup
     in high core count systems
   - It was used to provide an 85+% reduction in UDP send overhead on high core
     count systems see the link for a bit more detail:
