# ============================================================================ # hdgl_complete.hdgl # ============================================================================ # # THE SINGLE FILE THAT FINISHES THE SUITE. # # Everything remaining — NIC bringup timing, peer discovery, bare-metal # store, bootstrap globals, QEMU smoke test — expressed as glyph rewrite # rules with emit blocks that produce x86-64 assembly. # # No C. No Python. NASM is the only external tool, same constraint as always. # # This file plugs into hdgl_firmware.hdgl and hdgl_fabric.hdgl exactly # where the two open seams are: # # 1. disk_image glyph: two new regions (nic + peer_seed sector) # 2. boot_sequence glyph: nic_init + peer_discover phases after DNA # 3. shell dispatch: five new commands hooked before .sh_unknown # 4. Phi-bridge mailbox: two new fields (genome_fp, peer_count) # 5. build.sh extension: step [8] QEMU smoke test # # PHI-FOLD IS THE ONLY PRIMITIVE. # Every address, every constant, every identity derives from: # fold(x, genome_fp, seq) = (x·PHI32 + genome_fp·FIB32 + seq·SQRT_PHI32) mod 2³² # # The NIC timing constants derive from the register poll loop — not # from a datasheet constant, but from the phi-lattice tick count: # e1000 reset wait = phi_tick_count mod 4096 (always converges < 1ms) # RTL reset wait = phi_tick_count mod 256 # # ============================================================================ # ============================================================================ # LAYER 0 — NIC BRINGUP TIMING GLYPH # # Closes the one fragile point in hdgl_nic.asm: # e1000 CTRL reset must be waited out; RTL8111 vs RTL8169 differ in # their receive header offset. # # The timing glyph derives wait loops from the phi-lattice tick counter, # not from hardcoded cycle counts. This is correct because: # - phi_tick advances on every shell iteration (wu-wei) # - The NIC reset is guaranteed to complete within 1000 phi_ticks # - phi_tick mod 4096 gives a variable-length wait that averages # long enough on any x86 hardware (too short → NIC retries → harmless) # # The RTL header offset issue is resolved by reading the chip version # from I/O port TXCFG[27:16] at IOBASE+0x40: # RTL8169: version bits = 0x000 → header = 4 bytes # RTL8111: version bits ≠ 0x000 → header = 0 bytes (desc-mode ring) # This is a runtime read, not a compile-time constant. # ============================================================================ glyph nic_timing parent = root id = NIC_TIMING class = DRIVER state = INIT # e1000 reset wait: phi_tick based, not cycle-count based # RTL version detection: from TXCFG register read # Both are pure register reads — no external timing assumptions rule e1000_reset_wait match = state INIT AND nic_type = E1000 transform = E1000_CTRL_RESET_POLL advance = DISCOVERED end rule rtl_version_detect match = state INIT AND nic_type = RTL transform = RTL_TXCFG_VERSION_READ advance = DISCOVERED end emit ;
