Constructor & Destructor Documentation

ThreadedKernel::ThreadedKernel ( int argc, char ** argv )

Interpret command line arguments. ThreadedKernel::ThreadedKernel Interpret command line arguments in order to determine flags for the initialization (see also comments in main.cc) Definition at line 25 of file kernel.cc.

ThreadedKernel::~ThreadedKernel ( )

deallocate the kernel. ThreadedKernel::~ThreadedKernel Nachos is halting. De-allocate global data structures. Definition at line 71 of file kernel.cc.

Member Function Documentation

void ThreadedKernel::Initialize ( )

initialize the kernel -- separated from constructor because refers to "kernel" as a global. ThreadedKernel::Initialize Initialize Nachos global data structures. Separate from the constructor because some of these refer to earlier initialized data via the "kernel" global variable. Reimplemented in NetKernel, and UserProgKernel. Definition at line 50 of file kernel.cc. Referenced by UserProgKernel::Initialize().

void ThreadedKernel::Run ( )

do kernel stuff. ThreadedKernel::Run Run the Nachos kernel. For now, do nothing. In practice, after initializing data structures, the kernel would start a user program to print the login prompt. Reimplemented in NetKernel, and UserProgKernel. Definition at line 89 of file kernel.cc. Referenced by UserProgKernel::Run().

void ThreadedKernel::SelfTest ( )

test whether kernel is working. ThreadedKernel::SelfTest Test whether this module is working. Reimplemented in NetKernel, and UserProgKernel. Definition at line 106 of file kernel.cc. Referenced by UserProgKernel::SelfTest().
