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.
Lilblue Linux is a Gentoo-based, security-enhanced, fully featured XFCE4 desktop system for amd64, built on uClibc. Its userland utilities are not provided by busybox, but by coreutils, util-Linux, etc. It resembles a common Linux system with one exception: It uses uClibc as its standard C library and not the more common glibc, and so brings in some of the advantages of embedded systems. Security enhancements come from Gentoo's hardened toolchain and Grsec/PaX-patched kernel. The fully-featured XFCE4 desktop has software for browsing, email, word processing, multimedia, chat, games, and more.
Capstone is a disassembly framework with the target of becoming the ultimate disasm engine for binary analysis and reversing in the security community. Running on Windows, Mac OS X, Linux, FreeBSD, OpenBSD, and Solaris, it can disassemble ARM, ARM64 (ARMv8), MIPS, PPC, and x86 architectures. Capstone provides rich details about disassembled instructions along with useful semantic information.
cpuid.c is a very simple C abstraction that provides an interface to common cpuid feature flags. It can be useful when implementing dynamic CPU feature dispatch that relies on optional processor feature extensions or basic processor-specific variables. This package is meant to be a very simple feature detection interface that you can easily integrate into your project. It is not meant to be complex and it is geared for projects implementing dynamic CPU feature dispatch.
