In syscall emulation I suppose?

How much time approximately?

Can you provide a minimal reproducible C example so we can try to reproduce?

[gem5-users] gem5 takes a lot of time to load global data from program binary

[Nitish Srivastava]

Hi,

I am trying to run some benchmarks in gem5. These benchmarks have really
big matrices stored as global arrays. While simulating it seems like gem5
is taking a lot of time to just load these global matrices i.e. the time
difference between the time when I start gem5 simulation and the time when
the "main" function in the binary actually gets executed is huge. Is there
a way I can speed this up?

Thanks,
Nitish
