Trusted Firmware M – what’s cooking?
summary
Trusted Firmware-M is an open source PSA implementation for Arm M that ships two partition models: a shared-memory function-call model and an IPC/thread model, with static and proposed dynamic secure-context allocation. Work targets higher isolation levels (RFC and a level 2 isolation design, rudimentary level 3 proof-of-concept), secure interrupt handling via de-privileged sandboxed ISRs, concurrent context management prototype, and dual-core proof-of-concept; designs and some implementations are on public review.
