[async] Change ZX_WAIT_ASYNC_REPEATING to ZX_WAIT_ASYNC_ONCE This is a step towards removing ZX_WAIT_ASYNC_REPEATING. As part of this change, remove port_wait_repeating(), which is a direct consumer of ZX_WAIT_ASYNC_REPEATING, and instead rely on port_wait(). Change utests not use ZX_WAIT_ASYNC_REPEATING. ZX-3090 Test: port-test, threads-test pass. Change-Id: I7b769d7917345de2a756e0b5864dc6653f1b162b
Zircon is the core platform that powers the Fuchsia OS. Zircon is composed of a microkernel (source in kernel/...) as well as a small set of userspace services, drivers, and libraries (source in system/...) necessary for the system to boot, talk to hardware, load userspace processes and run them, etc. Fuchsia builds a much larger OS on top of this foundation.
The canonical Zircon Git repository is located at: https://fuchsia.googlesource.com/zircon
A read-only mirror of the code is present at: https://github.com/fuchsia-mirror/zircon
The Zircon Kernel provides syscalls to manage processes, threads, virtual memory, inter-process communication, waiting on object state changes, and locking (via futexes).
Currently there are some temporary syscalls that have been used for early bringup work, which will be going away in the future as the long term syscall API/ABI surface is finalized. The expectation is that there will be about 100 syscalls.
Zircon syscalls are generally non-blocking. The wait_one, wait_many port_wait and thread sleep being the notable exceptions.
This page is a non-comprehensive index of the zircon documentation.
