fingerprintd — the daemon shell.
|
||
|
|
|
||
|
|
Nothing here talks to hardware yet. The core (Fingerprintd:Sfs and the modules
|
||
|
|
that follow it) is being ported from the fp6 harness one wire format at a time,
|
||
|
|
each landing with tests that run without a phone; this entry point exists so
|
||
|
|
the executable target builds alongside them and so the version constant that
|
||
|
|
gates a package publish has a home.
|
||
|
|
|
||
|
|
What this will own, and why it has to be one long-lived process:
|
||
|
|
|
||
|
|
* the sensor rail (gpio29), reset (gpio74) and IRQ (gpio75) — one sensor
|
||
|
|
reset buys exactly one trustlet init, so whatever powers the sensor must
|
||
|
|
also hold the session;
|
||
|
|
* the QTEE session on /dev/tee0: client env, the QSEECOM-compat loader, and
|
||
|
|
the focal64 trustlet, loaded once;
|
||
|
|
* the storage listeners QTEE calls back into — gpfile 0x7000 and RPMB
|
||
|
|
0x2000 — served from a supplicant thread that must outlive every request,
|
||
|
|
because QTEE's listener table is global and an id is taken for as long as
|
||
|
|
the registration is held;
|
||
|
|
* net.reactivated.Fprint, so pam_fprintd and the desktop need no changes.
