x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU.. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance.
Blue Pill originally required AMD-V (Pacifica) virtualization support, but was later ported to support Intel VT-x (Vanderpool) as well. It was designed by Joanna Rutkowska and originally demonstrated at the Black Hat Briefings on August 3, 2006, with a reference implementation for the Microsoft Windows Vista kernel.
AMD GPUs contain certain additional functional units intended to be used as part of HSA. In Linux, kernel driver amdkfd provides required support. [9] [10] Some of the HSA-specific features implemented in the hardware need to be supported by the operating system kernel and specific device drivers.

It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. [1] KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. [2] KVM has also been ported to other operating systems such as FreeBSD [3] and illumos [4] in the form of loadable kernel modules.
In April 2005, AMD introduced a subset of SSE3 in revision E (Venice and San Diego) of their Athlon 64 CPUs. [2] The earlier SIMD instruction sets on the x86 platform, from oldest to newest, are MMX, 3DNow! (developed by AMD, no longer supported on newer CPUs), SSE, and SSE2. SSE3 contains 13 new instructions over SSE2. [3]
