Bump to 1.6.0 (workspace sync, no functional change). Fix the README
example that called the removed matches()/unlock() API — rewrite to the
real unlock_features()/unlock_bus() contract (+ ld/README).
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.
Track libfreemkv's finalized 3-capability Unlocker trait:
- unlock(...) -> unlock_drive(...)
- read_vid(...) -> read_volume_id(...)
- add set_max_read_speed(...)
set_max_read_speed issues the matched profile's set_speed_max_cdb
(0xBB SET CD SPEED, to max) over the raw transport; a profile without a
set_speed_max_cdb (or no matching profile) is a no-op so the drive stays at
its current speed. read_disc_keys_cdb is left untouched — inert profile data,
never issued, no trait method.
README: document the 3-method contract, the delete-to-comply fallback, and the
#2-only boundary (freemkv uploads RAM microcode to an already-bootloader-flashed
drive; the permanent bootloader flash #1 is the owner's one-time manual step,
never automated). Left a marked MakeMKV attribution placeholder for the
maintainer to author.
Tests: renamed read_vid tests; added set_max_read_speed tests (issues the CDB
when present, no-op when the profile carries none).
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).
