Function Documentation

tz_arch_init_ns_signal()

void tz_arch_init_ns_signal

(

void

)

Initialize the platform-specific mechanism that delivers secure-side wake-up requests to the normal world.

Called once during normal-world TrustZone initialization. Weakly defined as a no-op so platforms without a wake mechanism still link; in that case secure-only events do not autonomously wake the normal world.

tz_normal_request_poll()

bool tz_normal_request_poll

(

void

)

Request a poll of the normal-world TrustZone process.

   Safe to call from any context, including NS interrupt
   handlers. The platform NS-side wake handler invokes this
   when the secure side has signalled that it has work for
   the normal world to drain.
