- bootloader, kernel, userboot, and devmgr now support FLAG_EXTRA for container headers as well as item headers - bootloader generates new style headers for prepended bootdata items when it detects a new style container header - mkbootfs generates large container headers when generating bootdata images with crc32 enabled - bootloader version bumped to 0.6.0 to mark the point of compatibility needed for kernels once we throw the switch to use new headers exclusively Change-Id: Ifcb78d62f882ddd869da8d73ffe774a0f7937bc0
Magenta
Magenta is the core platform that powers the Fuchsia OS. Magenta 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 Magenta Git repository is located at: https://fuchsia.googlesource.com/magenta
A read-only mirror of the code is present at: https://github.com/fuchsia-mirror/magenta
The Magenta 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.
Magenta syscalls are generally non-blocking. The wait_one, wait_many port_wait and thread sleep being the notable exceptions.
