This page explains the special opcodes that can be used in M5 to do checkpoints etc.
The m5 Utility (FS mode)
The m5 utility (see util/m5/) can be used in FS mode to issue special instructions to trigger simulation specific functionality. It currently offers the following options:
- ivlb: Deprecated, present only for old binary compatibility
- ivle: Deprecated, present only for old binary compatibility
- initparam: Deprecated, present only for old binary compatibility
- sw99param: Deprecated, present only for old binary compatibility
- exit [delay]: Stop the simulation in delay ticks.
- resetstats [delay [period]]: Reset simulation statistics in delay ticks; repeat this every period ticks.
- dumpstats [delay [period]]: Save simulation statistics to a file in delay ticks; repeat this every period ticks.
- dumpresetstats [delay [period]]: same as resetstats; dumpstats
- checkpoint [delay [period]]: Create a checkpoint in delay ticks; repeat this every period ticks.
- readfile: Print the file specified by the config parameter system.readfile. This is how the the rcS files are copied into the simulation environment.
- debugbreak: Call debug_break() in the simulator (causes simulator to get SIGTRAP signal, useful if debugging with GDB).
- switchcpu: Cause an exit event of type, "switch cpu," allowing the Python to switch to a different CPU model if desired.
