ywkang	d2c92b8a18	Wire PE_MMU to router mesh for MmuMapMsg delivery ... Add router → PE_MMU edge so MmuMapMsg can reach PE_MMU via the router mesh. Unskip all PE_MMU fabric tests. 339 passed, 0 skipped Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-04 18:10:42 -07:00
ywkang	5917b3497c	Replace xbar/bridge/single-NOC with explicit router mesh (ADR-0019) ... - Remove xbar_top/bot, bridge, single noc node from topology - Each cube_mesh.yaml router becomes a separate SimPy node (r{row}c{col}) - HBM_CTRL consolidated to single node per cube, attached to all routers - All traffic (DMA data + PE command) routes through same router mesh - Update AddressResolver (no slice suffix), PathRouter (_adj_local) - Update ADR-0002~0019, SPEC.md to remove xbar/bridge references - Regenerate SVG diagrams for new topology structure - Skip cross-SIP PE_TCM and PE_MMU routing tests (not yet wired) 326 passed, 13 skipped Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-04 17:51:28 -07:00
ywkang	08812eda58	Add virtual memory support: PE_MMU, VA allocator, fabric MmuMapMsg ... Implement VA/MMU layer (ADR-0011 Phase 1) enabling Triton kernels to use contiguous virtual addresses on sharded tensors. Key changes: - PE_MMU component: hybrid inbox (MmuMapMsg) + sync translate() for PE_DMA - VirtualAllocator + PEMemAllocator: free-list with coalescing - MmuMapMsg/MmuUnmapMsg fabric path with SIP-level routing - DPPolicy-based mapping: replicate=local, sharded=broadcast - Tensor lifecycle: del + weakref cleanup, context manager - Rename: TensorHandle.pa→addr, DmaReadCmd.src_pa→src_addr, ctx→torch Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-26 00:01:47 -07:00
