Revert "[syscalls] Remove vestigal vmar_..._old() calls." This reverts commit 70f3d16f38cd2f0227d56fce09e4845693b1ba48. Reason for revert: Chromium and some of its third-party dependencies were apparently still using the old names, so we'll need to update the dependencies, and Chromium, and wait for everything to roll, before we can re-land this. :( Original change's description: > [syscalls] Remove vestigal vmar_..._old() calls. > > Test: CQ > Change-Id: I8b1f1dd01c5cae31de2da4b9ba0e9f41c0fca137 TBR=kulakowski@google.com,davemoore@google.com Change-Id: Idee154db1da8111ccdd0b738ff45d5745f20ee1e No-Presubmit: true No-Tree-Checks: true No-Try: true
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
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.
