The main module and entrypoint
Various facilities of the kernels are implemented as submodules. The most important ones are:
trap
: Handles all cases of switching from userspace to the kernelsyscall
: System call handling and implementation
The operating system also starts in this module. Kernel code starts
executing from entry.asm
, after which rust_main()
is called to
initialize various pieces of functionality. (See its source code for
details.)
We then call batch::run_next_app()
and for the first time go to
userspace.
