docs(spec): DPDK 23.11.5 -> 24.11.6 LTS upgrade — spec generation phase
Phase one (spec) of the F-Stack embedded DPDK upgrade from 23.11.5 LTS to
24.11.6 LTS. This commit lands the 6 deliverable spec documents (per the
plan.md §0.2 7-doc deliverable list, of which plan.md itself is .gitignored
as a local-only AI planning artifact per ea8aac1). Phase two (M1~M6
implementation: tree replace + 3-patch port + glue fix + tests + docs sync)
will follow in subsequent commits.
Spec generation flow (harness + spec-driven + 5 sub-agent team):
- dpdk-23-patch-scout : F-Stack local DPDK patch inventory
- dpdk-24-analyzer : 24.11.6 vs 23.11.5 key change analysis
- diff-comparator : rte-layer file-level diff + symbol intersection
- spec-author : 5 spec docs authored
- gate-keeper : independent review (99-review-report.md PASS)
Documents (6 files, 1708 lines total):
00-overview-and-glossary.md (142 lines) Project overview + glossary +
scope; 4 core decisions table.
01-requirements-spec.md (154 lines) FR-D-1..11 + NFR-D-1..6;
R-D1..D12 risks; DP-A1..A8
decided + DP-B1..B7 closed at
spec phase + DP-C1..C3 deferred
to phase two; gate matrix G1..G7.
02-current-and-target.md (299 lines) F-Stack's 3 historical patches
inventory (5f3768c + 62f1c34
+ 9271817 — diff with upstream
23.11.5 has empty differential
beyond these 3 commits) + key
24.11.6 changes:
- VERSION 23.11.5 -> 24.11.6
- ABI_VERSION 24.0 -> 25.0
- lib/ count 57 -> 59
(+argparse +ptr_compress, both
opt-in, F-Stack 0 ref)
- lib/eal +2962 lines (largest
delta; eal_bus_cleanup() still
unconditional in 24.11.6 stable
-> 9271817 patch must rebase)
- lib/timer 0 line delta (only
__rte_cache_aligned macro
position adjustment)
- lib/net rte_ip.h 21.6KB -> 210B
(split into rte_ip4.h +
rte_ip6.h; F-Stack uses 10
struct rte_ipv{4,6}_hdr but
only includes rte_ip.h —
stub-include forwarding will
make M4 compile pass)
- KNI completely removed in
24.11.6 (R-D2 escalated P2->P1)
- igb_uio not in upstream (F-Stack
maintains own version since DPDK
21.05 removed it)
- meson minimum 0.53.2 -> 0.57
04-port-and-impl.md (490 lines) M1..M6 milestones with full
executable bash command lists;
two-commit semantic layering
('replace:' + 'port:' merged per
plan.md §4.4 / DP-A8) plus
optional 'fix:' if glue layer
needs source-level adaptation;
14-24 turn estimate.
06-test-and-acceptance-spec.md (385 lines) Single-doc test spec covering
TC-A..G:
- TC-A helloworld functional
- TC-B helloworld perf (curl-bench
100/1000, phase-5b methodology
reused, +-5% trade-off threshold)
- TC-C nginx single-proc functional
- TC-D nginx single-proc perf
- TC-E nginx multi-proc functional
+ 9271817 worker-exit & 62f1c34
reload validations
- TC-F nginx multi-proc wrk
functional only (no horizontal
scaling perf — user runs that on
physical machines later)
- TC-G F-Stack phase-2 + vlan-test
historical features single-pass
smoke
99-review-report.md (238 lines) gate-keeper review: PASS, no
P0/P1 blocking. Closed 4 DP-Bx
items at spec phase via direct
measurement. One must-fix-before-
M2: KNI A/B decision (FF_KNI=0 or
preserve KNI subtree).
Spec backed up to /data/workspace/dpdk-stable-24.11.6/f-stack-lib/test-configs/
dpdk-23-24-upgrade/ (matches the freebsd-15.0/f-stack-lib model).
Workspace mandate: 0 direct rm/kill/chmod throughout. Local commit only;
