The CSS (DVD-Video) bus-auth unlocker as a first-class external plugin, peer
to freemkv-unlock-ld. CssUnlocker impls libfreemkv::Unlocker — matches
DiscKind::Css, self-guards against the hardware (refuses NotApplicable without
issuing a CSS CDB if the drive reports a non-DVD profile), then runs the
libfreemkv bus-auth primitive (unlock_css_reads). libfreemkv keeps the bus-auth
+ keyless descramble; this crate owns the unlocker impl. Additive: a consuming
binary opts in with one register_unlocker(CssUnlocker::new()) line; the in-tree
built-in stays until clients are rewired.
libfreemkv owns the Unlocker trait + registry; this repo holds the concrete
unlocker plugins. LibreDrive moves to the ld/ member (package freemkv-unlock-ld
unchanged). Workspace root + repo README describe the general-unlocker model;
adding an unlocker = a new member + one register_unlocker line in the consumer.
libfreemkv dep is the crates.io version; local dev resolves it via the
gitignored .cargo/config.toml patch.
New crate freemkv-unlock-ld — the LibreDrive Unlocker implementation,
split out of libfreemkv so the library stays firmware-clean on crates.io.
Owns everything about HOW MediaTek MT1959 drives are firmware-unlocked:
- profiles.json (the bundled drive-profile database + DriveProfile parse)
- src/platform/mt1959/* (variant-A/B firmware upload + unlock handshake)
- WRITE_BUFFER / MODE SELECT upload, unlock CDBs, disc-speed calibration
Exposes LibreDrive::new() implementing libfreemkv::Unlocker (name/matches/
unlock). Plug it in with one line at process start:
libfreemkv::register_unlocker(Box::new(freemkv_unlock_ld::LibreDrive::new()));
Depends on libfreemkv (path-patched via gitignored .cargo/config.toml in
dev) for the trait, ScsiTransport, DriveId, and Result. README notes it's
the LibreDrive unlocker (attribution to be added by owner).
