ZenScraper
A command line tool to collect AMD uCode!
Overview
ZenScraper gathers AMD CPU microcode (uCode) patches from public upstream repositories, extracts the individual patches from their containers, and stores them under a single directory with a consistent, content-addressed naming scheme. Patches that already exist are de-duplicated by SHA-256, and a hash mismatch on a same-named patch is reported as an error.
Currently supported sources:
- Linux Firmware — the
linux-firmwarerepository (amd-ucodecontainers, extracted into individual patches). - Platomav CPUMicrocodes — the platomav/CPUMicrocodes repository (AMD patches).
Each source is walked across its full git history, so superseded patches are collected as well as current ones.
Installation
pip install zenscraper
Usage
Run the tool to scrape every supported source into the current directory:
zenscraper
Options:
| Option | Default | Description |
|---|---|---|
--workdir, -w |
./workdir |
Directory for temporary and cached files (the cloned repos are kept here between runs). |
--outdir, -o |
. (current directory) |
Directory where the collected patches are stored. |
Output
Collected patches are written to a patches/ subdirectory of --outdir. Each
file is named after its parsed header fields and a short content hash, for
example:
family19_cpuidA20F12_rev0A201210_date20240611_enc00_sha1a2b3c4d5e6f.bin
The fields encode the CPU family, CPU ID, update revision, build date, encryption flag (when present) and the first 12 hex digits of the patch's SHA-256 hash.
