Assignment No. 6 Aim: Write X86/64 ALP To
Assignment No. 6 Att Perm Oral Total Sign (2) (5) (3) (10) Aim: Write X86/64 ALP to switch from real mode to protected mode and display the values of GDTR, LDTR, IDTR, TR and MSW Registers. 6.1 Theory: Real Mode: Real mode, also called real address mode, is an operating mode of all x86-compatible CPUs. Real mode is characterized by a 20-bit segmented memory address space (giving exactly 1 MiB of addressable memory) and unlimited direct software access to all addressable memory, I/O addresses and peripheral hardware. Real mode provides no support for memory protection, multitasking, or code privilege levels. Protected Mode: In computing, protected mode, also called protected virtual address mode is an operational mode of x86-compatible central processing units (CPUs). It allows system software to use features such as virtual memory, paging and safe multi-tasking designed to increase an operating system's control over application software. When a processor that supports x86 protected mode is powered on, it begins executing instructions in real mode, in order to maintain backward compatibility with earlier x86 processors. Protected mode may only be entered after the system software sets up several descriptor tables and enables the Protection Enable (PE) bit in the control register 0 (CR0). Control Register : Global Descriptor Table Register This register holds the 32-bit base address and 16-bit segment limit for the global descriptor table (GDT). When a reference is made to data in memory, a segment selector is used to find a segment descriptor in the GDT or LDT. -

Bringing Virtualization to the X86 Architecture with the Original Vmware Workstation
12 Bringing Virtualization to the x86 Architecture with the Original VMware Workstation EDOUARD BUGNION, Stanford University SCOTT DEVINE, VMware Inc. MENDEL ROSENBLUM, Stanford University JEREMY SUGERMAN, Talaria Technologies, Inc. EDWARD Y. WANG, Cumulus Networks, Inc. This article describes the historical context, technical challenges, and main implementation techniques used by VMware Workstation to bring virtualization to the x86 architecture in 1999. Although virtual machine monitors (VMMs) had been around for decades, they were traditionally designed as part of monolithic, single-vendor architectures with explicit support for virtualization. In contrast, the x86 architecture lacked virtualization support, and the industry around it had disaggregated into an ecosystem, with different ven- dors controlling the computers, CPUs, peripherals, operating systems, and applications, none of them asking for virtualization. We chose to build our solution independently of these vendors. As a result, VMware Workstation had to deal with new challenges associated with (i) the lack of virtual- ization support in the x86 architecture, (ii) the daunting complexity of the architecture itself, (iii) the need to support a broad combination of peripherals, and (iv) the need to offer a simple user experience within existing environments. These new challenges led us to a novel combination of well-known virtualization techniques, techniques from other domains, and new techniques. VMware Workstation combined a hosted architecture with a VMM. The hosted architecture enabled a simple user experience and offered broad hardware compatibility. Rather than exposing I/O diversity to the virtual machines, VMware Workstation also relied on software emulation of I/O devices. The VMM combined a trap-and-emulate direct execution engine with a system-level dynamic binary translator to ef- ficiently virtualize the x86 architecture and support most commodity operating systems. -

Protected Mode - Wikipedia
2/12/2019 Protected mode - Wikipedia Protected mode In computing, protected mode, also called protected virtual address mode,[1] is an operational mode of x86- compatible central processing units (CPUs). It allows system software to use features such as virtual memory, paging and safe multi-tasking designed to increase an operating system's control over application software.[2][3] When a processor that supports x86 protected mode is powered on, it begins executing instructions in real mode, in order to maintain backward compatibility with earlier x86 processors.[4] Protected mode may only be entered after the system software sets up one descriptor table and enables the Protection Enable (PE) bit in the control register 0 (CR0).[5] Protected mode was first added to the x86 architecture in 1982,[6] with the release of Intel's 80286 (286) processor, and later extended with the release of the 80386 (386) in 1985.[7] Due to the enhancements added by protected mode, it has become widely adopted and has become the foundation for all subsequent enhancements to the x86 architecture,[8] although many of those enhancements, such as added instructions and new registers, also brought benefits to the real mode.

Supervisor-Mode Virtualization for X86 in Vdebug
Supervisor-Mode Virtualization for x86 in VDebug Prashanth P. Bungale, Swaroop Sridhar, and Jonathan S. Shapiro { prash, swaroop, shap } @ cs.jhu.edu Systems Research Laboratory The Johns Hopkins University Baltimore, MD 21218, U. S. A. March 10, 2004 Abstract Machine virtualization techniques offer many ways to improve both debugging and performance analysis facilities available to kernel developers. A minimal hardware interposition, exposing as much as possible of the underlying hardware device model, would enable high-level debugging of almost all parts of an operating system. Existing emulators either lack a debugging interface, impose excessive performance penalties, or obscure details of machine-specific hardware, all of which impede their value as debugging platforms. Because it is a paragon of complexity, techniques for emulating the protection state of today's most popular processor – the Pentium – have not been widely published. This paper presents the design of supervisor-mode virtualization in the VDebug kernel debugger system, which uses dynamic translation and dynamic shadowing to provide translucent CPU emulation. By running directly on the bare machine, VDebug is able to achieve an unusually low translation overhead and is able to exploit the hardware protection mechanisms to provide interposition and protection. We focus here on our design for supervisor-mode emulation. We also identify some of the fundamental challenges posed by dynamic translation of supervisor-mode code, and propose new ways of overcoming them. While the work described is not yet running fully, it is far enough along to have confidence in the design presented here, and several of the techniques used have not previously been published. -
