-===== Project description & Approach to solving the problem ===== +(Details as to how you intend to approach the problem, if applicable. May include ideas as to how to break the problem down into smaller parts, or notes on research you need to do before settling on your final approach to solving the problem)
-Bhyve hypervisor that runs guest operating system inside a virtual machine +
-(parameters like the number of virtual CPUs, amount of guest memory and input-output +
-connectivity can be specified with command line parameter). It has a +
-software emulator of a small number of instructions which needs to be tested using +
-Intel XED tools and after decoding it needs to produce a data structure describing +
-the opcode, operands, and flags or vice versa. The main purpose of this project is +
-to provide a test for Bhyve instructions. The tests are a tiny guest operating system +
-that generally executes few lines of C and assembler test code in order to obtain +
-its PASS/FAIL result. This test harness provides %%FreeBSD%% and software +
-emulator to check the accuracy of their instructions. It is often used for quick and +
-dirty bug reproducer. I will try to provide simplicity to test harness so that it is +
-easy to verify they are correct, easy to maintain and easy to use in timing +
-measurement. +
-Since this %%FreeBSD%% OS supports multiple architectures currently (i386, amd64, +
-ARM, MIPS, PPC, sparc64). I am trying to provide test harness which supports all +
-these architectures. I am creating a test harness for the instructions emulation +
-code using the Intel XED tool which is the software library for encoding and +
-decoding x86(IA-32 instructions set and Intel 64 instructions set) instructions. +
-information and produces a data structure describing the opcode, operands, and +
-flags. From these, we obtain the PASS/FAIL result of the emulation.+
