dev/pktfifo.cc:
need to checkpoint _reserved
dev/pktfifo.hh:
When clearing, clear _reserved
size() is used for determining how many bytes are in the fifo
ready to be pulled, so we don't want to add _reserved
avail() on the other hand is used for determining how much
free space is in the fifo for adding packets.
adjust the implementation of empty() and full() to reflect this.

This is release m5_1.0_beta1 of the M5 simulator. This file contains brief "getting started" information and release notes. For more information, see http://m5.eecs.umich.edu. If you have questions, please send mail to m5sim-users@lists.sourceforge.net. WHAT'S INCLUDED (AND NOT) ------------------------- Since you're reading this file, presumably you've managed to untar the distribution. The archive you've unpacked has three subdirectories: - m5: the simulator itself - m5-test: regression tests and scripts to run them - ext: less-common external packages needed to build m5 (currently ply and libelf) M5 is a capable, full-system simulator that current supports both Linux 2.4/2.6 and the proprietary Compaq/HP Tru64 version of Unix. We are able to distribute Linux bootdisks, but we are unable to distribute bootable disk images of Tru64 Unix. If you have a Tru64 license and are interested in obtaining disk images, contact us at m5-dev@eecs.umich.edu. WHAT'S NEEDED ------------- -GCC(3.X) -Python(2.2.2+) WHAT'S RECOMMENDED ------------------ -MySQL (for statistics complex statistics storage/retrieval) -Python-MysqlDB (for statistics analysis) GETTING STARTED --------------- The following steps will build and test the simulator. The variable "$top" refers to the top directory where you've unpacked the files, i.e., the one containing the m5, m5-test, and ext directories. There are three different build targets and three optimizations in each level: Target: ------- ALPHA - Syscall emulation simulation KERNEL - Linux full system simulation KERNEL_TLASER - Tru64 Unix full system simulation Optimization: ------------- m5.debug - debug version of the code with tracing and without optimization m5.opt - optimized version of code with tracing m5.fast - optimized version of the code without tracing and asserts cd $top/m5/build scons TARGET/OPTLEVL # e.g. KERNEL/m5.opt, use -j N if you have a MP system cd $top/m5-test ./do-tests.pl -B ALPHA # test what you just built ./do-tests.pl -B KERNEL # test what you just built # wait for tests to run... # should end with "finished do-tests successfully!"
