From: Abdul Mutaal Ahmad Date: Fri, 1 Jul 2016 14:30:15 +0000 (-0500) Subject: misc: Separate stats file for SystemC-gem5 co-simulation X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1051223318360a74c46c0f818bdc599287a51064;p=gem5.git misc: Separate stats file for SystemC-gem5 co-simulation In previous versions of systemC-gem5 coupling statistics were not updated for the systemc-gem5 simulation. systemC-gem5 simulation only need the previously built config.ini file and normal gem5 simulation has to be run once to generate config.ini file. Thus stats.txt inside the m5out folder is redundant for systemC-gem5 simulation. A new stats file is now generated with the all the statistics for systemC-gem5 simulation. This will also resolve the stats issue in tlm-sysmtemC simulation.
