MON 60 (N500M) Subfunction Table - Authoritative

Every MON 60 subfunction code 000B-177B, with its purpose and server-side handler, taken from the SINTRAN worker source: SINTRAN/NPL-SOURCE/NPL/5P-P2-MON60.NPL

  • Purpose column = the verbatim % FUNCTION=nnn: comment in that source (authoritative).
  • Handler column = the routine named in the INTEGER ARRAY 5IFUNC dispatch (line 1319). 5NOPAR = generic path (no special input-parameter marshalling; the message is forwarded to the ND-500 through the common 5NOPAR routine). ILLFUNC = illegal/unimplemented (EILFUNC). 0 = table slot unused.
  • Client column = the name used by the ND-100 monitor program's thunk (from Developer/MON/calls/60B_N500M.yaml), and the thunk address in nd-500-mon-j04.prog (see SINTRAN/ND500/nd-500-mon/mon60-callers/INDEX.md).

IMPORTANT: NPL is a different build revision than the L07 binary. Treat purposes/handler names as authoritative LOGIC, confirmed where the L07 thunk exists. FUNCMAX=177 (5P-P2-MON60.NPL:287); codes 155-167 are annotated "free for patching". All codes octal.

This table is the reference for the per-command folders under SINTRAN/ND500/nd-500-mon/mon60-callers/.

Notes and reconciliations

  1. 5NOPAR is not "no-op". It is the common input path: the handler computes the process number and forwards the message to the ND-500 without special parameter marshalling (5P-P2-MON60.NPL:1889). A subfunction can be fully functional and still dispatch to 5NOPAR (e.g. 041 READ INTERFACE STATUS, 060 LIST MEMORY CONFIG).

  2. Subfunction 130 = START STANDARD DOMAIN, per the NPL, not "place domain". The yaml client name PLADOM and the NDInsight table sit on this code, but the authoritative purpose is START STANDARD DOMAIN (ISFSYDOM), one of the standard-domain family 127/130/131 (define/start/delete). The operator command PLACE-DOMAIN most likely brackets a place with 055 START-PLACE + 006 LOAD-ONE-SEGMENT + 056 END-PLACE rather than issuing 130. Which operator command reaches 130 needs the command dispatch table to confirm; do not assume it is PLACE-DOMAIN.

  3. This binary extends past the documented table. The NDInsight yaml documents 0-142B. Codes 143B-173B are real here: 143 activate-program, 144 change-CPU, 145 start-standard-domain-from-op.com, 150 list-time-queue, 154 debug-swapper, 156 read-system-info, 157 write-control-store (alias of 024), 160/161 new-domain-format place/define, 166 dump-trace-memory, 170 read-CPU-type+mic-version, 172 read-HW-scratch-register-file, 173 set-CPU-status. The remaining 5NOPAR slots above 142B have no FUNCTION= comment and are marked undocumented.

  4. Duplicate WRITE CONTROL STORE: 024 and 157 share the handler IWCNT (the NPL notes "equal for func=157"). Likewise 023 READ CONTROL STORE notes "equal for func=157" in the read direction.

  5. 147 dispatches to ILLFUNC in the array, yet a FUNCTION=147 comment ("ESCAPE TYPED WHILE RUNNING STANDARD DOMAIN STARTED FROM S3 OP.COM.") exists - the escape path is reached by a mechanism other than the 5IFUNC index. Noted, not resolved.
