# Linux Kernel Assembly → Explanation Dataset

A dataset of disassembled Linux kernel functions paired with structured natural-language explanations, built from the [Linux Commits Dataset (Zenodo 10654193)](https://zenodo.org/records/10654193).

Each row corresponds to a single compiled function extracted from a `.c` or `.h` file touched by a **Bug-Fix Commit (BFC)** or **Bug-Introducing Commit (BIC)** in the Linux kernel git history. Source files are compiled with `gcc -O2 -g -fno-inline -fno-omit-frame-pointer` and disassembled with `objdump -d -S` (AT&T syntax, source-interleaved).

Intended for training or evaluating models on **assembly code understanding**, specifically, generating natural language explanations from disassembled Linux kernel functions.

## Schema

| Column | Type | Description |
|---|---|---|
| `bfc_hash` | `string` | Hash of the bug-fix commit in the pair |
| `bic_hash` | `string` | Hash of the bug-introducing commit in the pair |
| `commit_hash` | `string` | The specific commit this function was extracted from |
| `commit_type` | `string` | `"bfc"` (bug-fix commit) or `"bic"` (bug-introducing commit) |
| `filename` | `string` | Source file path within the kernel tree (e.g. `kernel/sched/core.c`) |
| `func_name` | `string` | Name of the disassembled function |
| `asm` | `string` | `objdump -d -S` output for one function (AT&T syntax, source lines interleaved) |
| `explanation` | `string` | Structured description: commit type, function name, author, date, commit message, and role |
| `commit_message` | `string` | First 512 characters of the commit message |

---

## Usage

```python
from datasets import load_dataset

ds = load_dataset("theelderemo/linux-asm-pairs", split="train")
print(ds["asm"])
print(ds["explanation"])
```

Filter to only bug-fix commits:
```python
bfc_only = ds.filter(lambda x: x["commit_type"] == "bfc")
```

## Data Pipeline

1. BFC/BIC pairs sourced from `bfc_bic.csv` in [Zenodo record 10654193](https://zenodo.org/records/10654193)
2. Full diffs fetched from a local bare clone of the Linux kernel git repo (snapshot: 2023-11-12)
3. Changed `.c` / `.h` files compiled with `gcc -O2 -g -fno-inline -fno-omit-frame-pointer`
4. Functions extracted via `objdump -d -S --no-show-raw-insn`
5. Explanations constructed from Perceval-parsed commit metadata
