RCore
rCore is a Rust-based operating system kernel and microkernel designed for Linux compatibility. It functions as a self-hosted development kit that implements a system call interface to support the execution of standard Linux userspace applications.
The system is designed for modularity, featuring a mechanism for loading and integrating kernel modules into the active environment without requiring a system reboot.
The kernel provides core operating system capabilities, including virtual memory mapping for process isolation, a disk-based file system for data persistence, and a layered network protocol stack. It also includes an interrupt-driven asynchronous input and output system and a signal coordination mechanism for communication between isolated processes.
