H A DPlotPowerStates.py12269:7aa513567d8b Wed Jun 21 06:17:00 EDT 2017 Radhika Jagtap <radhika.jagtap@arm.com> util: Add script to plot DRAM low power sweep

This change adds a script to generate graphs from the stats file
output by the configuration script low_power_sweep.py.

The graphs show stacked bars for time spent and energy consumed
wherein each component of the stacked bar represents a DRAM power
state (Idle, Refresh, Active, Active Power-down, Precharge Power-down
and Self-refresh). The script generates one plot per delay value. It
also generates a pdf (--pdf option) in which the graphs are laid out
such that you can easily compare how the increasing delay and other
swept params affect the resulting energy.

H A Dsc_main.ccdiff 13097:6efbd43ab80e Sun Aug 26 18:53:00 EDT 2018 Gabe Black <gabeblack@google.com> systemc: Handle sc_stop called from sc_main correctly.

When in sc_main, sc_is_running will return true but we're not going
to run any gem5 events since we're currently in the sc_main Fiber. In
that case, we need to do the sc_stop work inline.

If we're actually running and not just paused, then we do still want to
schedule the work of sc_stop to happen as its own event since that will
happen before returning to sc_main, and actually will likely be the
mechanism by which sc_main starts executing again.
