Revert "[zircon-internal] Remove deprecated zx_crashlogger_request_backtrace" This reverts commit d2f6e543aa4e4139794cbce12e0e77af4e802147. Reason for revert: This breaks global integration, and is blocking the Zircon roller. Original change's description: > [zircon-internal] Remove deprecated zx_crashlogger_request_backtrace > > All clients have been migrated to backtrace_request(). > > Test: no functional change > Change-Id: I33f4b7b4489b6be4fd75a649003a04676c629fd9 TBR=kulakowski@google.com,jamesr@google.com Change-Id: Ie49b31ec6fcb886c39f064bd9be96ab430712697 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
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.
