Understanding the Memory Layout of Linux Executables

Required tools for playing around with memory:

• hexdump
• objdump
• readelf
• xxd
• gcore

#!/usr/bin/env bash

brew install openssl

git clone git://anongit.mindrot.org/openssh.git
cd openssh

# The './configure' script does not exist, so we have to build it
autoreconf

In general, check the crt/host_config.h file to find out which versions are supported. Sometimes it is possible to hack the requirements there to get some newer versions working, too :)

Thrust version can be found in $CUDA_ROOT/include/thrust/version.h.

A non-maskable interrupt (NMI) is an interrupt type which differs from standard interrupt mechanism by enforcing attention from the interrupt processor (usually the CPU).  This solution discusses an NMI is in more depth and how they are handled.

### What is an Interrupt ? ###

Modern systems architecture has created tightly coupled connect between system components.  Work for components can be handed off to a component for completion.  Rather than wait for the component the main CPU can be tasked to do other pending work.

When the component has completed its work it will raise a signal to the main processor.  The main processor considers this signal an "interrupt", as the current work on the CPU will be interrupted immediately   Each component has a number assigned to it.

### Why "mask" an interrupt ? ###
