Rosenblatt Phase-2: userspace regcmd builder — U3 wrapper + CNA stage (4a)
- librocket.{c,h}: thin ioctl wrapper over the rocket accel uAPI (open + CREATE_BO/
SUBMIT/PREP_BO/FINI_BO + mmap). Compiles with -I/usr/include/drm.
- rkt_matmul_cna.{c,h} + cna_defs.h: CNA-stage regcmd emit for an INT8 matmul-as-
1x1-conv, faithful port of Mesa rocket fill_first_regcmd's CNA section. Compiles
clean (-Wall -Wextra), 85 emits. Cross-validated: two independent ports (dspark
Montessori-scaffolded + big-pickle autonomous) agree at the emit level.
- rkt_matmul_coredpu.{c,h} + coredpu_defs.h: CORE+DPU+PC scaffold (empty body,
@@INSERT@@ marker). Params struct incl. float scales + 3 DMA-addr fields.
Body port is WIP: 82 DPU emits + float requant + PC tail remain (needs slicing).
- *_reference.txt: curated Mesa rocket emit excerpts + register defines (implementer
reference bundles).
Implementer: dspark (DeepSeek-V4-Flash NVFP4, local) via Montessori scaffolding;
autonomous CNA also produced by opencode/big-pickle. Multi-model benchmark in
claude-memory reference_dspark_implementer. NOT golden-verified (faithful-to-Mesa;
needs a Mesa build or NPU hardware to byte-check).
