# FC01 — plan iteracji diagramów w Hazard3
|
||||
|
||||
## Zasada
|
||||
|
||||
Kursor porusza się po diagramie, nie po przypadkowych liniach programu.
|
||||
Każda kotwica ma jeden z dwóch kontraktów:
|
||||
|
||||
- `CODE` — otwiera właściwe źródło lub dowód ELF; nie uruchamia programu;
|
||||
- `RUN` — odtwarza program od czystego resetu do wskazanego checkpointu,
|
||||
ustawia Neovima i udostępnia zestaw wyrażeń GDB.
|
||||
|
||||
Ten sam snapshot może wystąpić w kilku perspektywach. Nie powtarza to
|
||||
eksperymentu: A2 pyta o strukturę, A6 o stan, a A7 o jakość dowodu.
|
||||
|
||||
## A1 CONTEXT — granice odpowiedzialności
|
||||
|
||||
| Step | Tryb | Otwórz | Pytanie kontrolne |
|
||||
|---|---|---|---|
|
||||
| 01 Application | CODE | `main()` | Czy aplikacja dotyka metadanych allocatora? |
|
||||
| 02 FreeRTOS API | CODE | wywołania `pvPortMalloc`, `vPortFree`, stats | Gdzie kończy się publiczny kontrakt? |
|
||||
| 03 heap_4 | CODE | upstream `heap_4.c` | Które funkcje wybierają, dzielą i scalają blok? |
|
||||
| 04 ucHeap | CODE | definicja `ucHeap[4096]` | Gdzie fizycznie leżą nagłówki i payload? |
|
||||
| 05 Hazard3 | CODE | test symboli ELF | Czy debugujemy dokładnie artefakt z karty? |
|
||||
|
||||
A1 nie ma checkpointu: opisuje architekturę, a nie zdarzenie runtime.
|
||||
|
||||
## A2 STRUCTURE — nagłówek, split i scalenie
|
||||
|
||||
| Step | Tryb / replay | Obserwuj | Warunek zaliczenia |
|
||||
|---|---|---|---|
|
||||
| 01 Header | CODE | `BlockLink_t`, `portBYTE_ALIGNMENT` | raw header=8 B, alignment=16 B, `xHeapStructSize`=16 B |
|
||||
| 02 Alignment | RUN E02 | `g_a`, `g_a_consumed` | A jest wyrównane, cały blok zużywa 48 B |
|
||||
| 03 Split | RUN E02 | `g_after_a_stats` | pozostaje 1 wolny blok i 4032 B |
|
||||
| 04 Address order | RUN E06 | `g_a`, `g_b`, `g_c`, stats | adresy rosną, a B rozdziela 2 wolne obszary |
|
||||
| 05 Merge previous | RUN E06 + step | `pxIterator`, `pxBlockToInsert` | poprzedni/lewy blok jest testowany i scalany pierwszy |
|
||||
| 06 Merge next | RUN E06 + step | powiększony blok i `pxNextFreeBlock` | następny/prawy blok jest scalany drugi |
|
||||
|
||||
Dla kroków 05–06 po replay E06:
|
||||
|
||||
```gdb
|
||||
tbreak prvInsertBlockIntoFreeList
|
||||
continue # wykonaj vPortFree(g_b)
|
||||
p pxIterator
|
||||
p pxBlockToInsert
|
||||
next # test poprzedniego/lewego sąsiada
|
||||
next # test następnego/prawego sąsiada
|
||||
```
|
||||
|
||||
## A5 FLOW — pełny przebieg
|
||||
|
||||
| Event | Operacja | Wartości RV32/Hazard3 | Dowód |
|
||||
|---|---|---|---|
|
||||
| E01 | reset/init | free=4080 | 1 blok, largest=4080 |
|
||||
| E02 | alloc A(24) | consumed=48, free=4032 | A != NULL, aligned=1 |
|
||||
| E03 | alloc B(40) | consumed=64, free=3968 | B != NULL, aligned=1 |
|
||||
| E04 | alloc C(16) | consumed=32, free=3936 | C != NULL, aligned=1 |
|
||||
| E05 | free A | free=3984 | 2 wolne bloki |
|
||||
| E06 | free C | free=4016 | 2 bloki, free > largest |
|
||||
| E07 | free B | free=largest=4080 | 1 wolny blok, minimum-ever=3936 |
|
||||
| E08 | oversized alloc | NULL | hook=1, asserts=0, layout=1, PASS=1 |
|
||||
|
||||
Każdy Enter na A5 wykonuje czysty replay do dokładnie jednego eventu. Nie
|
||||
kontynuujemy stanu pozostałego po poprzednim kroku.
|
||||
|
||||
## A6 STATE — znaczenie liczników
|
||||
|
||||
| Step | Replay | Hipoteza |
|
||||
|---|---|---|
|
||||
| 01 Free | E01 | current free i largest są równe |
|
||||
| 02 Allocated | E04 | przydziały zmniejszają current free do 3936 |
|
||||
| 03 Fragmented | E06 | total free może być większe od largest |
|
||||
| 04 Coalesced | E07 | current, largest i initial znów są równe |
|
||||
| 05 Minimum-ever | E08 | minimum-ever pozostaje 3936 mimo odzyskania areny |
|
||||
|
||||
## A7 RUNTIME — jakość dowodu
|
||||
|
||||
| Step | Tryb / replay | Co musi znaleźć się w dowodzie |
|
||||
|---|---|---|
|
||||
| 01 Source | CODE | blob źródła eksperymentu |
|
||||
| 02 ELF | CODE | SHA artefaktu i symbole upstream/checkpointów |
|
||||
| 03 Fragmented | RUN E06 | PC, 2 bloki, free=4016, largest<free |
|
||||
| 04 Memory | RUN E06 | adres `ucHeap`, adresy A/B/C i bajty nagłówków |
|
||||
| 05 Verdict | RUN E08 | final=initial, OOM NULL, hook=1, asserts=0, PASS=1 |
|
||||
|
||||
Snapshot do raportu jest kompletny dopiero wtedy, gdy łączy nazwę eventu,
|
||||
tożsamość ELF, pozycję programu i wartości rozstrzygające hipotezę.
|
||||
|
||||
## Świadomie pominięte perspektywy
|
||||
|
||||
- A3 DISPATCH — allocator nie ma callbacku ani mechanizmu dispatch;
|
||||
- A4 APPLICATION — konkretny eksperyment A/B/C jest pełnym A5;
|
||||
- A8 PATTERNS — first-fit i intrusive address-ordered list są już mierzalne w
|
||||
A2 i A5; osobny diagram powielałby materiał.
|
||||
|
||||
## Definition of done
|
||||
|
||||
1. Hostowe modele i adapter przechodzą `tests/test_host.sh`.
|
||||
2. ELF RV32 zawiera upstream `heap_4` oraz osiem symboli checkpointów.
|
||||
3. Hazard3 RTL kończy Task03 kodem `0`.
|
||||
4. E01–E08 spełniają wyrażenia z `debug_checkpoints`.
|
||||
5. Wszystkie kroki RUN mają `snapshot_ref`; kroki CODE nie udają runtime.
|
||||
6. SVG, HTML i TeX powstają z tego samego `json/card_source.json`.

||||
- budowa RV32I i kontrola symboli ELF;
|
||||
- Hazard3 RTL: zakończenie kodem 0 po 27308 cyklach;
|
||||
- osiem checkpointów obecnych w ELF;
|
||||
- walidacja JSON i odwołań `code_ref`/`snapshot_ref`;
|
||||
- kontrola PlantUML, SVG, HTML, TeX i siedmiostronicowego PDF;
|
||||
- TypeScript/React typecheck generatora.
|
||||
|
||||
## Braki materiału
|
||||
|
||||
- [ ] Zmniejszyć udział prozy.
|
||||
- [ ] Zastąpić akapity:
|
||||
- [ ] listami kontrolnymi;
|
||||
- [ ] tabelami wartości;
|
||||
- [ ] komendami do skopiowania;
|
||||
- [ ] punktami zatrzymania GDB;
|
||||
- [ ] kryteriami zaliczenia.
|
||||
- [ ] Szablon każdego taska:
|
||||
- [ ] `Cel` — maksymalnie 3 punkty;
|
||||
- [ ] `Uruchom` — komendy;
|
||||
- [ ] `Zatrzymaj` — breakpoint/watchpoint;
|
||||
- [ ] `Obserwuj` — symbole i pamięć;
|
||||
- [ ] `Oczekuj` — wartości host/RV32;
|
||||
- [ ] `Zmień` — jeden eksperyment;
|
||||
- [ ] `Zaliczenie` — mierzalna checklista.
|
||||
- [ ] Przenieść pełne listingi C/ASM do dodatku.
|
||||
- [ ] Pierwsze strony PDF przeznaczyć na kartę prowadzącego i przebieg lekcji.
|
||||
|
||||
## Kolejność wznowienia K01
|
||||
|
||||
1. Zamknąć wymagania w bezpośrednim poprzedniku `inf/structures`.
|
||||
2. Dodać testy wyniku do K01.
|
||||
3. Dodać kontrakt `stem-card.yaml`.
|
||||
4. Uruchomić 10/10 tasków na Hazard3 RTL.
|
||||
5. Dodać checkpointy K10.
|
||||
6. Zbudować K10 dla `rp2350-rv`.
|
||||
7. Wgrać i debugować K10 przez JTAG.
|
||||
8. Przebudować README/PDF do formatu list-first.
|
||||
9. Wykonać końcowy review techniczny i dydaktyczny.
|
||||
|
||||
## Bezpośredni poprzednik
|
||||
|
||||
- Seria: `inf`.
|
||||
- Karta: `structures`.
|
||||
- Repozytorium: `lab-rv32i-c-structures`.
|
||||
- Przejście wymagane przed K01:
|
||||
- [ ] `struct` i `typedef`;
|
||||
- [ ] struktura samoreferencyjna;
|
||||
- [ ] pole `next`;
|
||||
- [ ] przejście po liście;
|
||||
- [ ] wstawianie elementu;
|
||||
- [ ] wartownik;
|
||||
- [ ] `sizeof`, padding i wyrównanie na AMD64/RV32;
|
||||
- [ ] niezmienniki listy;
|
||||
- [ ] obserwacja w GDB.
|
||||
## Pozostaje poza zakresem tej iteracji
|
||||
|
||||
- próba na fizycznym RP2350/Pico 2 W;
|
||||
- commit i publikacja — wymagają osobnego polecenia.
