Disko is a user interface application framework for the fast and simple development of flexible applications on embedded Linux systems, with a particular focus on interactive user interfaces. It is high-performance and easy to learn, and due to its architecture is well suited to creating complex applications.
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.
