An IPC Language For The Whole Operating System
summary
Fuchsia uses a single IPC language, FIDL, to define kernel syscalls, driver APIs and every IPC boundary; the kernel Zircon exposes about 150 syscalls and userland drivers so IPC performance matters. The system compiles FIDL with a front end into an IR (fiddlec JSON), generates bindings for C++ Rust Dart Go, and uses a wire format compatible with C structs so decoding needs no allocations. Tools like fiddlecat and fiddlebolt exist. GPU teams try to beat it and cannot; it runs on real devices.
