eLua (Embedded Lua) aims to introduce the programming language Lua to the embedded software development world. Lua is the perfect example of a minimal yet fully functional language. The aim of the project is to have a fully functional Lua development environment on a microcontroller (Lua interpreter, modules appropriate for microcontroller environments, and editor) without the need to install a specific toolchain on the PC side.
Xvisor is a type-1 hypervisor that aims to provide a monolithic, light-weight, portable, and flexible virtualization solution for ARMv5, ARMv6, ARMv7a, ARMv7a-ve, ARMv8a, x86_64, and other CPU architectures. It primarily supports full virtualization, and hence supports a wide range of unmodified guest operating systems. Paravirtualization is optional and is supported in an architecture independent manner (such as VirtIO PCI/MMIO devices) to ensure that no changes are required in the guest OS.
airbag_fd provides drop-in crash handlers for POSIX (particularly for embedded Linux). It dumps registers, backtraces, and instruction streams to a file descriptor. It is intended to be self-contained and resilient. Where possible, it will detect and intelligently handle a corrupt state (for example, jumping through a bad pointer or a blown stack). The harvesting and reporting of the crash log is left as an exercise for the reader.
