Unofficial Blackhole Documentation

Unofficial documentation for the Blackhole P100A / P150, assembled from reverse-engineering, disassembly, and hands-on experiment. Walks from a self-contained intro through chip architecture (NoC, Tensix tiles, RISC-V cores, L1, memory map), the 3-kernel matmul model, SFPI kernel writing, circular-buffer dataflow, the JIT build and dispatch pipeline, firmware boot sequence, and multi-host scaling. The author notes most pages were drafted by coding agents, with a `human/` folder that is explicitly hand-written.
