Hiļ¼Steve
I configure m5 to dump statistic result every 1 million cycles when in
simulation, which the config.ini is like this:
[stats]
descriptions=true
dump_cycle=0
dump_period=1000000
dump_reset=true
ignore_events=
mysql_db=
mysql_host=
mysql_password=
mysql_user=
project_name=test
simulation_name=test
simulation_sample=0
text_compat=true
text_file=m5stats.txt
But it is strange that some of latency statistic results is larger than
dump_period, like dcache I got
cpu.dcache.overall_miss_latency 12839992
# number of overall miss cycles
cpu.dcache.overall_miss_rate 0.182594
# miss rate for overall accesses
cpu.dcache.overall_misses 134820
# number of overall misses
cpu.dcache.overall_mshr_hits 105250
# number of overall MSHR hits
cpu.dcache.overall_mshr_miss_latency 1757871
# number of overall MSHR miss cycles
cpu.numCycles 1000000
# number of cpu cycles simulated
As you can see that cpu.dcache.overall_miss_latency is the number of overall
miss cycles, why it is lager than the total cycles simulated ? Is there
anything wrong ?
thanks
