## 3.0.26 - 29/07/25
- Added single tray galaxy reset option
- Bumped luwen from 0.7.5 -> 0.7.10
  - Chip detect now doesn't wait for eth to train for the 6U galaxy's, allowing multi tray resets to happen independently
- Updated readme with the new reset option

## 3.0.25 - 29/07/25
- Added packaging

## 3.0.24 - 04/07/25
- Now users have 2 galay reset modes available
  - glx_reset: resets the galaxy, informs users if there has been an eth failure
  - glx_reset_auto: resets the galaxy upto 3 times if eth failures are detected

## 3.0.23 - 03/07/25
- Bumped luwen 0.7.3 -> 0.7.5 to fix cargo lock compatibilty issue

## 3.0.22 - 02/07/25
- Bumped tt-tools-common 1.4.16 -> 1.4.17
- Bumped luwen 0.7.2 -> 0.7.3
- Bumped smi 3.0.21 -> 3.0.22

## 3.0.21 - 26/06/25

- Added option to not re-init chips after reset
- Updated galaxy 6u reset option from --ubb_reset to -glx_reset
- Removed the a3 arc message before doing a 6u reset, meaning we can reset even when chips are not pcie accessible
- Added eth link check and return failure if any of the eth links have a LINK_INACTIVE_FAIL_DUMMY_PACKET failure

## 3.0.20 - 04/06/25

- Chore - bumped tt-tools-common version to fix driver version check for compatability with tt-kmd 2.0.0

## 3.0.19 - 30/04/25

- Fixed an issue preventing the telemetry thread from being dispatched when the user clicked tab 2

## 3.0.18 - 22/05/25

- Added BH and WH UBB board type support
- Removed the dependency on tt-tools-common for this info

## 3.0.17 - 13/05/25

- Added proper telemetry heartbeat checks for Grayskull

## 3.0.16 - 12/05/25

- Used new ResetTypes from tools-common to simplify reset code
- Added a heartbeat spinner to the telemetry pane. We expect this spinner to update about twice per second. If the spinner is not moving, this indicates new telemetry is not being fetched.

## 3.0.15 - 24/04/25

- Patch for the ubb_reset to just discover local only post reset. Looks like eth port status 2 has been re-used to mean connected and pyluwen waits for it to clear, leading to eth timeout.

## 3.0.14 - 21/04/25

- Added wh ubb reset via command line `tt-smi --ubb_reset`. Intention is that this command line option will be removed and integrated into `tt-smi -r` after we update board detection with the correct external naming.
- Removed some unused imports and code - no functional changes

## Unreleased

### Added

- `flash`: `--update-boot-images` writes the bundle's bootloader and recovery
  images even when the board already holds the same ones, for provisioning and
  board recovery.

### Changed

- `flash`: the boot-critical images (`cmfw`, `safeimg`, `safetail`, `failover`)
  and the ROM and failover descriptor tables are now left alone when the board
  already holds the same content, so a routine update no longer opens a
  power-loss window on the path by which a board boots at all. Whether an image
  is the same is decided by the SHA-256 and key hash that `imgtool` records in
  it, because signing is not reproducible: two builds of the same source differ
  only in the trailing signature. Pass `--update-boot-images` for the previous
  behaviour of writing them unconditionally.

### Fixed

- `flash`: a P300 chip running recovery firmware publishes no board id, so the
  pairing check filed it as not a P300, left its sibling alone in a group of
  one, and dropped both halves of the card from the flash list -- refusing the
  board because of the chip that most needed flashing. Such a chip is now
  identified by its PCI subsystem id, which carries the same UPI whatever the
  chip is running.
- `boot_fs`: `tt_boot_fs_fd.image_tag_str()` compared each `c_uint8` tag byte
  against the string `"\0"`, which never matched, so NUL padding was included in
  the decoded tag. Tags shorter than 8 bytes (e.g. `cmfw`) now compare correctly.
  This makes `read_tag` robust across the multi-table boot filesystem layout
  (ROM, failover, and mutable descriptor tables).

# Changelog

The **canonical, complete release log lives in [`debian/changelog`](debian/changelog)** —
that's the file the `.deb` packages are built from and where every release is
recorded in full. This file is a friendly pointer plus a summary of the most
recent releases; it deliberately does not duplicate the whole history.

To see everything:

```bash
less debian/changelog          # full history
git tag                        # released versions
```

## Recent releases

Releases 0.11.1 through 0.13.9 are recorded only in `debian/changelog`; this
list is a summary and is not kept for every release.

### 0.13.10
- **Add**: Inference view (`i`) shows the port and chips each model runs on,
  for example `:8000 · chips 0,1`, on each roster row or in a header line for a
  single model.
- **Add**: `--tt-smi-reset-behavior` (`ignore`, `inform` default, `dazzle`,
  `demo`). A `tt-smi -r` in another terminal shows in the status bar of every
  view. `dazzle` adds a takeover box with one of five animations (Quiet
  Notice, 128 Blackholes, a BBS sysop chatbot, TT-TREKLIKE, Silly Cetacean);
  `demo` plays all five at start and on every real reset.
- **Change**: the legend (`l`) and explain (`!`) text for the Training,
  Inference, HivemindSweeper, Insights, Defrag and Memory Castle views matches
  what they draw now; the Help panel shows the reset status segment.

### 0.11.0
- **Add**: Training view (`t`) — a full-screen visualization of a live
  tt-train run, drawn as the network it is: a character grid of transformer
  blocks and attention heads fed by token particles, a loss "mountain range"
  under a twinkling aurora nightscape that opens up as the model converges,
  plus chip telemetry alongside it.
- **Auto-attaches with no command**: scans running processes for a tt-train
  example binary (`nano_gpt`, `mnist_mlp`, `linear_regression`), then resolves
  `/proc/<pid>/fd/1` to find and tail that process's log. Checkpoint saves
  are detected by mtime on the run's rolling checkpoint file.
- **Honest limitation**: tt-train's per-step stream can only be tailed if its
  stdout was redirected to a real file at launch (`> train.log`). If fd 1 is
  a pipe or tty, retroactively reading it is an OS-level impossibility, not a
  gap in this tool — the view says so and falls back to what it can still
  see (process liveness, chip telemetry, and checkpoint mtime) rather than
  drawing a fake loss curve. Gradient norms, MFU, and throughput counters
  aren't emitted live either, so the view derives tokens/sec and ETA only
  from what it can actually read.
- Nine independent color channels (loss magnitude, run-history timeline,
  loss-delta direction, forward/backward sweep cadence, cache compile/steady
  state, checkpoint bursts, plus chip temp/power) — see the new legend and
  explain overlays.

### 0.10.3
- **Security fix**: a direct-vLLM host process's own `PATH` was forwarded
  onto the `sh` the monitor spawns to probe it — a bare `Command::new("sh")`
  lookup re

## [0.1.29] - 2026-09-07

Correctness pass on what a TT-QuietBox 2 actually ships. The three-path venv
activation blocks added in 0.1.25 offered `~/.tenstorrent-venv` as the "QB2
pre-installed" environment for TT-NN and vLLM, and described a QB2 as "4
independent single-chip devices". Neither claim is true, and this release
corrects both everywhere they were found — including in this repo's own
`CLAUDE.md`, `llms.txt`, and two lessons outside the original diff
(`content/pages/FAQ.md`, `monkeypatch-ttnn.md`) that had never been touched
by the earlier topology/venv corrections this built on.

Verified against `tt-installer`'s `install.m4`, the published `tt-metalium`/
`tt-metalium-models` GHCR image configs, `tt-inference-server`'s `run.py`,
and tt-metal `main` — plus live end-to-end testing on a QB2-equivalent
board — rather than other Tenstorrent docs, which largely descend from the
same stale source note this release supersedes.

### Fixed

**`~/.tenstorrent-venv` is not a TT-NN or vLLM environment.** `tt-installer`
only ever installs `tt-smi`, `tt-flash` and (opt-in) `tt-topology` into it, so
`import ttnn` and `import vllm` both fail there. TT-NN lives **only** inside
the TT-Metalium container (`tt-metalium`, where `python3` is
`/opt/venv/bin/python3`); vLLM runs in a container `tt-inference-server`
launches. Corrected everywhere this was asserted or assumed:
- The "QB2 pre-installed image" activation line in all 11 TT-NN blocks across
  `explore-metalium`, `video-generation-ttmetal`, `animatediff-video-generation`,
  `cookbook-game-of-life`, `cookbook-mandelbrot`, `cookbook-particle-life`,
  `cookbook-image-filters`, `cookbook-audio-processor`, and the four lessons
  that used it as a premise (`lfs-00-intro`, `lfs-05-train-and-run`,
  `ct1-understanding-training`, `ct4-finetuning-basics` — their `ttml`-needs-a-
  source-tree conclusions were already correct; only the premise changed).
- `tt-installer`'s own "may not include the container wrapper" framing —
  backwards: a QB2 *has* the wrapper (it's the only way to reach TT-NN) and
  has no host-side TT-NN. Its "Test TT-Metalium" button and pytest demo
  example were also broken independent of this: missing `-c` (so `bash` tried
  to run the whole command string as a filename), a bare `ttnn.__version__`
  that doesn't exist on the built package (now `getattr(ttnn, "__version__",
  "import OK")`), and — for the demo — the wrong container and a Blackhole
  demo path that moved in tt-metal's January 2026 reorg (now
  `tt-metalium-models` + `models/demos/vision/segmentation/ufld_v2/blackhole`,
  with `--install-metalium-models-container` named as off-by-default).
- `vllm-production`'s new "On a QB2 — read this first" section (pointing a

# Changelog

All notable changes to this project will be documented here.

## 2.0.0.dev0

- Establish `tt-transformers` as the standalone package for TTTv2 modules,
  runtime components, sampling, and twelve experimental model families.
- Add reproducible package builds and CPython 3.10/3.12 host validation.
- Add serialized Wormhole and Blackhole hardware qualification policy.
- Require `ttnn==0.79.0`. Trace capture now acknowledges its allocations to
  ttnn's trace allocation tracker (tenstorrent/tt-metal#53735).
- Rename the warmup override `trace_prefill_warmup_seq_lens` to
  `prefill_warmup_seq_lens`.
- Remove the TTTv1 sampler surface from `tt_transformers.sampling`
  (`generator`, `tt_sampling`, `tt_penalties`). Use
  `tt_transformers.modules.sampling`.
- With any trace mode, a prefill bucket that has no captured trace is served
  eager instead of failing. The first eager request per bucket logs one
  warning, and the load logs which buckets are traced.
- A traced configuration whose warmup lengths leave a servable prefill bucket
  uncompiled is refused at load with a `ValueError`.
- A `max_seq_len` that isn't a prefill bucket boundary now warms the bucket it
  pads to.
- Warmup compiles the prefix-cached variant of every prefill bucket a cached
  prompt can reach, including the top one. A configuration whose `max_seq_len`
  is itself the top bucket gains one such case per sampling path, captured as a
  trace where that bucket is traced; the Llama-3.1-8B N300 trace region grows
  to 70 MB for it.
  The Qwen3-32B T3K trace region grows from 120 MB to 150 MB: its batch-32
  cases gain three prefix-cached 1024 traces and need up to 125 MB.
- Default KV-cache sizing leaves room for the decode page table. A paged KV
  cache narrower than the decode page table is refused at load with a
  `ValueError`, instead of failing on the first decode step.
- On-device greedy sampling breaks an exact logit tie by the lowest token id,
  as host argmax does. Before, the pick depended on the batch slot and could
  vary between runs.

This is a developer preview. No model is promoted beyond the support status in
`SUPPORT.md` and its example manifest.

# Changelog

All notable changes to TT-Bio are recorded here. Versioning is [SemVer](https://semver.org);
releases are cut from a commit that has passed the on-hardware test suite (see `RELEASING.md`).

## [Unreleased]

### Fixed

- **A BindCraft 2 out-of-memory refusal says how much of the card the failing trajectory
  allocated.** It used to call everything allocated on the card "held by this fold", and in one
  reported campaign three quarters of that had been held before the trajectory started. A
  campaign now reads the card at each trajectory boundary and the refusal prints both parts; when
  most of it was inherited it points at `resume=true` instead of at the fold's size (#19).

- **A process that used a Tenstorrent card exits on its own, with its own status.** A BindCraft 2
  campaign could finish its work and then exit 139, or hang with SIGTERM ignored after an
  out-of-memory refusal, in teardown after Python was done. tt-bio now ends the process once it
  has closed the card, with the status the program chose, before the C++ destructors of tt-metal
  and XLA run. The stderr filter that tt-bio forked at import is gone; the nanobind leak report it
  dropped is still dropped, and `--debug` (or `TT_BIO_DEBUG_STDERR=1`) shows it (#20).

## [0.13.0] - 2026-10-08

Your own objective and your own outputs, on the models tt-bio already ships. BindCraft 2's design
loss takes terms you write, every structure model writes its full confidence matrices, and a fold
can carry an output head of your own.

### Added

- **A BindCraft 2 loss you can change.** `bindcraft2.loss_terms` adds a term of your own,
  reweights or switches off any of BindCraft 2's 37, or replaces what one computes, from ordinary
  Python with the settings file untouched. A term reaches the gradient, the mutation and
  acceptance scoring and `losses.csv` alike, on the card and on BindCraft 2's own JAX trunk.
  `bindcraft2.check_gradient` grades a term against float64 central differences, and a term whose
  gradient is silently zero is refused by name before a campaign spends on it. With no custom term
  the design loop is unchanged. Worked example: `examples/bindcraft2_custom_loss.py`; reference:
  [`docs/bindcraft2.md`](docs/bindcraft2.md#custom-loss).
- **Confidence exports for every structure model.** `--write_pae` now writes `<name>_pae.npz` with
  the full PAE matrix, the PDE matrix and contact probabilities from the model's own distogram,
  plus a JSON sidecar naming each array's shape and units, for Boltz-2, OpenDDE, OpenFold3,
  OpenBind-0, ESMFold-2, RF3, Protenix and AF2-IG. ESMFold-2 and AF2-IG compute a full PAE matrix
  for the first time, and OpenFold3, OpenBind-0, RF3 and AF2-IG report the chain-pair ipTM matrix
  in `results.json`. `--contact_cutoff` sets the contact distance. Protenix has no contact
  probabilities and AF2-IG no PDE, and the sidecar says so.
  [`docs/confidence-outputs.md`](docs/confidence-outputs.md).
- **An extension surface.** `tt-bio predict --

# Changelog

All notable changes to TT-Atom are recorded here. Versioning is [SemVer](https://semver.org);
releases are cut only from a commit that has passed the on-hardware release gate — accuracy
parity, no OOM across the supported size range, no perf or UX regression, and a clean install
smoke (see `RELEASING.md`).

## [Unreleased]

Behaviour changes are all in the knobs and the caches, not in the models: every numeric path is
byte-identical to 0.3.0.

### Fixed
- The release gate's perf leg no longer decides by luck. It took one measurement per model against
  a fixed 15% threshold, and on a p150a the throughput spread between runs reaches that threshold
  on its own: in the gate run that closed this entry, `uma-s-1-omol-batch` drew 88.9, 104.4 and
  104.8 sys/s, and the first of those alone is a 20% shortfall against the baseline. The leg now
  waits for every other process to let go of a card and gates the median of three independent
  runs, printing all three. With no quiet window it measures anyway and reports a shortfall as
  `GAP`, since a contended run is not evidence of a regression.
- `benchmarks/_harness.host_quiet()` reported the host busy forever. It grepped process command
  lines for `tt_bio`, which matches any agent whose own arguments merely mention it; it asks the
  kernel who holds a `/dev/tenstorrent` node now. The three benchmarks that wait for a quiet host
  used to burn their full 40-minute budget and stop without measuring.
- The edge-bucketing speedup in the README and `docs/orb-port.md` is re-measured and now names the
  environment it was taken in. It said 1.4x cold wall-clock on a 20-system screening stream; two
  draws on the pinned tt-metal source build give **1.11x and 1.14x** (235.1 / 236.5 s unbucketed
  against 210.9 / 207.6 s bucketed). What bucketing saves is compiles, and that is unchanged and
  exact: 20 distinct edge shapes collapse to 7 buckets and 2350 fewer kernel files are built,
  identical to the file across both draws. The wall-clock ratio fell because a compile costs about
  half what it did in whatever environment produced the earlier number — which that log does not
  record, so the three subprocess benchmarks now stamp `ttnn_version` next to `git_sha`.
- `benchmarks/_harness.sandbox_env` resolves the sandbox `$HOME`. A relative `--workdir` reached
  the child as a relative `$HOME`, and tt-metal resolves that against the child's own working
  directory: it died deep in the JIT build with "Failed to open compile failure log file" and a
  path that reads as correct. `bench_compile_pain.py` also defaulted to `--card 3`, a card that
  does not exist on the host this repo is routed to.
- `TT_ATOM_SCATTER_THRESHOLD` is documented. It is the node count above which UMA's dense one-hot
  scatter gives way to the linear path, and therefore what bounds DRAM on a large cell, but it
  appeared in no doc.
- The release gate reads `OVERALL: PASS` again. Both Orb perf rows were seeded on a stock `ttnn`
  0.68.

# Changelog

All notable changes to tt-forge-compiletron are documented here.

## [Unreleased]

### Added
- `docs/kv-cache-bench.md` — teaching companion for the StaticCache KV cache
  benchmark, explaining the two-graph pattern and why static shapes matter

---

## [1.6.0] — 2026-06-30

### Added
- **StaticCache KV cache decode benchmarking** — `bench_decode.py` now compiles
  a second forge graph for the decode step using `transformers.StaticCache`.
  The StaticCache is embedded in `KVDecodeWrapper` as a submodule so forge
  traces K/V tensors as model state and emits `FillCache`/`UpdateCache` ops.
  Falls back to full-recompute for models that don't support `cache_position`.
- `_try_kv_decode()` function — detects model dtype to avoid bfloat16/float32
  mismatches, resolves tokenizer from loader or AutoTokenizer, pre-fills cache
  on CPU before forge compilation.
- Bestiary `decode_note` field now records the method used per model
  ("StaticCache KV cache" vs "no KV cache — full recompute per step").

### Changed
- Decode results updated for all 5 stages — GPT-2 2.30→5.52 tok/s, OPT
  3.98→5.05 tok/s, Phi-2 1.48 tok/s (new), Falcon 3.30 tok/s (new),
  LLaMA-LoRA 2.86 tok/s (new), Gemma-LoRA 2.40 tok/s (new), and more.

---

## [1.5.0] — 2026-06-30

### Added
- **`scripts/bench_decode.py`** — dedicated LLM decode benchmark measuring
  TTFT, prefill tok/s, and decode tok/s for all compiled causal LMs.
  Subprocess isolation + tt-smi health check prevent hardware lockups.
- **Leaderboard columns** — TTFT, Prefill tok/s, Decode tok/s, Params (M)
  replace the old Infer p50 / Throughput columns in `docs/leaderboard.html`.
- 5 benchmark stages: Stage 1 (GPT-2, OPT), Stage 2 (Phi-2, BLOOM, CodeGen),
  Stage 3 (Falcon, Allam, LLaMA-LoRA, Gemma-LoRA), Stage 4 (Qwen 2.5,
  Phi-1 LoRA), Stage 5 (DeepCogito, DeepSeek Coder, frontier models).
- `params_m` field added to all benchmarked bestiary entries.
- `hf:` loader prefix for frontier HuggingFace models loaded without a
  tt-forge-models seed loader.

### Changed
- Bestiary `throughput_unit` relabeled from generic `tok/s` → `prefill_tok/s`
  for all 54 causal LM entries to prevent confusion with decode throughput.

---

## [1.4.0] — 2026-06-29

### Added
- **`scripts/install.sh`** — turn-key smart installer: hardware pre-check,
  hugepages, disk space, forge venv, XLA venv, mesh descriptor probe,
  tt-forge-models clone, stale-shm cleanup. Outputs color-coded summary table.
- **RAM/DRAM budget calculator** — skips models whose weights exceed available
  system RAM + per-chip DRAM; prevents OOM crashes at load time.
- **`scripts/setup-venvs.sh`** — minimal venv setup script for clean Ubuntu
  24.04 installs on Tenstorrent Blackhole hardware.
- Self-contained patches directory — tt-forge-models fixes applied at
  expedition startup without modifying upstream.
- `--ephemeral` / `--evict-failures` flags — evict HF weight cache after
  each model to reclaim disk space on small-storage machines.

### Changed

# Changelog

All notable changes to tensix-viz are documented here.

## [1.3.2] - 2026-09-28

### Fixed

- **Cluster views no longer collapse to their caption's width**
  (`src/cluster.js`). Cluster tiles are empty divs with no width of their own,
  so a shrink-to-fit parent sized the whole widget to its one-line spec text —
  Galaxy SC's 128 chips rendered as 2.7px dots. The tile grid now gets a
  preferred width from its column count (32px tiles, or 10px dots above 64
  chips) and `max-width: 100%`, so it still shrinks on phones.
- **Zoomed cluster breadcrumb no longer covers the spec caption**
  (`tensix-viz.css`). `.tv-cluster.tv-zoomed-in` reserves room at the top for
  the "Cluster › Server N" breadcrumb.

### Docs site (landing page)

- Hero and two-column sections now stack at 1120px instead of 900px. Between
  those widths the QB2 hero chips were squeezed to ~120px and the Memory code
  block hid up to ~140px of each line; the hero now gets full 340px chips there.
- Code blocks wrap at ≤800px instead of hiding most of each line in a sideways
  scroll box (the Quick-start block hid ~400px per line on a phone).
- Phones: tighter padding around the hero system (chips 85px → 119px at
  375px wide), and `kernel_dispatch` may wrap so the mode table fits.

## [1.3.1] - 2026-09-28

### Fixed

- **Chips in a card/system no longer come out at different sizes**
  (`src/card.js`, `src/chip.js`). `TensixViz` caps its drawing size to its
  parent's `clientWidth` once, at construction. `CardViz` builds chips one at a
  time into a flex row, so each chip measured the room its predecessors had
  left — on the docs hero, QB2's second chip in each card rendered at roughly
  half the size of the first. Card chips now pass the new
  `fitContainer: false` option and keep their full logical size; CSS fits them
  (`.tv-chip-wrapper { flex: 0 1 auto; min-width: 0 }`).
- **Shrunk canvases are no longer squished.** The inline `style.height = Hpx`
  overrode `.tv-chip-wrapper canvas { height: auto }`, so whenever
  `max-width: 100%` narrowed a canvas its height stayed put (aspect ratio 0.8
  instead of 1.42). Canvases now get `max-width: 100%`, `height: auto` and an
  explicit `aspect-ratio`, so they scale cleanly after construction too.
- `.tv-card`, `.tv-system`, `.tv-card-wrapper` and `.tv-cluster` can shrink to
  their container (`max-width: 100%` / `min-width: 0`).

### Docs site

- Hero and "chip anatomy" grids use `minmax(0, 1fr)` tracks; a bare `1fr`
  couldn't shrink below the Memory section's `<pre>`, which pushed the page
  sideways even on desktop.
- The mode reference table scrolls inside its own box on phones.
- Hero theme buttons are grouped with the canvas they theme (they were a stray
  third grid cell under the hero text).
- Examples: demo cards can shrink below their canvas's preferred width, page
  padding scales down on phones, and the theme toolbar wraps.

## [1.3.0] - 2026-09-24

### Added

- **`setActivity(value)` and `setProgress(value)`**

Booth — Changelog
=================

## Booth 0.6.0

### Runtime

- `kath run`, `kath build` and `kath doctor`, so one command builds a source
  and runs it on whatever device is there (Zane Hambly, 2026-09-14)

### Backends

- `--nvidia-cubin` writes a cubin the card will load, with no NVCC anywhere in
  the chain. All 67 of ggml-cuda's files now reach the IR
  (Zane Hambly, 2026-09-09)

### Frontend

- `constexpr` and `const` objects fold at every use, and anything the folder
  cannot evaluate refuses with E128 (Zane Hambly, 2026-09-03)

- class templates, specialisations, default template arguments and
  `enum class` parse, so 47 of ggml-cuda's 67 files reach the lowerer
  (Zane Hambly, 2026-09-04)

- the lowerer's tables no longer run out of room on a large translation unit,
  taking ggml-cuda's lowering errors from 774 to 210 (Zane Hambly, 2026-09-04)


## Booth 0.5.3

### Runtime

- #169: the runtime is split by where it runs, the `BC_ERR_*` codes no
  longer collide, and the examples and NVIDIA harness are built
  (Zane Hambly, 2026-08-23)


### Frontend

- variadic template parameter packs, several `.cu` files as separate
  translation units, `mma.sync` and `mfma` lowering, and an i1 that no
  longer strides by zero (Zane Hambly, 2026-09-03)

- `(a) + (b)` adds again; the parser treated any parenthesised identifier as a
  type name without asking whether it named one, so the left operand vanished
  into a cast with no diagnostic (Zane Hambly, 2026-09-03)

- the cast test is now the type name registry, so the registry has to be
  complete. Template type parameters, `using X = T` aliases and the type names
  sema resolves without a typedef (`size_t`, `uint32_t`, `float4` and the rest)
  all reach it. A compound literal through a typedef, `(pair){1, 2}`, parses
  for the first time, and `sizeof(name)` where the name is a type reads as a
  type rather than an expression (Zane Hambly, 2026-09-03)

- llama.cpp's ggml-cuda preprocesses, all 67 files; `#pragma once` is
  honoured, variadic and multi-line macro invocations expand, and an
  expansion too big for the output buffer is E053 rather than an
  unterminated buffer the lexer reads past (Zane Hambly, 2026-09-03)

- `kath --mlir` reads MLIR text, no LLVM in the path. Čertík's pure-C
  reader vendored under `src/mlir/vendor` (mlir 826b69c9, corec a160199d),
  reached only through `src/mlir/mlir_fe.c` (Zane Hambly, 2026-08-11)

- `src/mlir/lower.c` walks the parsed module into BIR: `func.func`, `return`,
  `arith.constant` and every arith binop, compare and conversion the reader
  classifies. From there it is the pipeline CUDA and Triton already use, and
  MLIR reaches all four backends. `--mlir --pp` reprints instead
  (Zane Hambly, 2026-08-11)

- an op outside the subset stops the lowering and names itself. Skipping it
  would leave a function that compiles and computes something else
  (Zane Hambly, 2026-08-11)

- five fixes to the vendored reader, all worth upstreaming, and four of them

# Changelog

Notable changes per release. Format loosely follows
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/);
this project does not yet promise SemVer compatibility on the RPC
wire format or library API surface (we're not 1.0).

## Unreleased

V2 virtio-dispatch redesign. The kick ring + completion ring + host-
side throttle that grew up around #184 are gone; in their place is a
per-(slot, queue) dirty bitmap in BRISC L1. The bitmap is level-
sensitive — guest QUEUE_NOTIFY storms coalesce into a single set
byte, so the dispatch path can't fall behind under any burst. Wire
incompatible with 0.9.0; `TENSIX_PROTOCOL_VERSION` bumped 4 → 5.

### Added

- **V2 dirty-bitmap dispatch** (`#187` / `#188` / `#189`). BRISC
  writes 1 to `CTRL_OFF_DIRTY[slot][queue]` on every guest
  QUEUE_NOTIFY; the daemon's `Dispatcher` clears the byte and
  dispatches each pass. Replaces V1's 2048-entry kick ring +
  daemon-side `consume_kick_ring_pass` consumer.
- **V2 processed-cursor table** at `CTRL_OFF_PROCESSED`. Daemon
  publishes `used.idx` after each successful dispatch so
  warm-resume reads cursors directly without re-probing guest
  DRAM.
- **`bhx_notify_events_total`, `bhx_dispatch_passes_total`,
  `bhx_dispatch_queues_drained`** Prometheus counters surface the
  new dispatch path. The burst regression test (`scripts/
  soak_virtio_burst.py`) asserts `dispatch_passes_total > 0` to
  confirm the workload reached the new path.
- **`scripts/soak_virtio_burst.py`** — multi-queue burst regression
  test. Sustains 16-job direct=1 fio randwrite + a tight
  `printf` loop to `/dev/console`, samples `/metrics` every 1 s,
  and verifies the daemon log contains zero
  `kick.*drop|rescue|throttle.*ENGAGE` matches.
- **`DaemonState.chip_reset_this_session`** flag — gates
  `maybe_opportunistic_reset_board` so 4-way parallel cold boots
  reset the chip exactly once, not once per L2CPU. Without this
  the second-and-later resets blip the chip while earlier-booted
  L2CPUs hold mmap pages, SIGBUSing their workers.
- **`Dispatcher` (was `KickPoller`)** with documented testability
  seam (`CtrlL1Access` trait); `drain_dirty_bitmap` is unit-tested
  against an in-memory L1 fake covering all five visit/clear
  semantics cases plus the address-formula pins.

### Changed

- **`KickPoller` → `Dispatcher`**, plus `kick_poller` → `dispatcher`
  field on `DaemonState`, `tensix-kick-poller` → `tensix-dispatcher`
  thread name, `[kick-poller]` → `[dispatcher]` log tag,
  `kicks_consumed` → `dispatches_total`,
  `last_kick_slot_queue` → `last_dispatch_slot_queue`. Pure
  rename; no behavior change. V1 vocabulary scrubbed throughout
  the codebase (firmware, daemon, scripts, docs).
- **`CTRL_SIZE` shrinks 36 KiB → 4 KiB**. V2 footprint is ~1.5 KiB;
  the rest is reserved for future fields.
- **Stats-page offsets repacked** — V1 `STATS_OFF_KICK_DROPS`,
  `STATS_OFF_COMPL_EVENTS`, `STATS_OFF_LAST_COMPL` retired with
  V1 (#190); deprecated PRECAP / BLINDCAP / POSTCAP slots dropp
