Hello,
I am following the Getting started instructions, I am stuck at the
beginning!
"Creating a simple configuration script".
I am using the current stable version of gem5 on a Debian (buster) system.
1. `build/X86/mem/mem_interface.cc:793: warn: DRAM device capacity (8192
Mbytes) does not match the address range assigned (512 Mbytes)`
I managed to fix this by increasing `system.mem_ranges` to 8GB.
Buried somewhere on the internet is a comment about something defaulting to
8GB.
2. `warn: No dot file generated. Please install pydot to generate the dot
file and pdf.`
I have installed this with `sudo apt install python-pydot
python-pydot-ng graphviz` . Could this be because my system is running in
server mode (no GUI)?
3. *The SEG. FAULT:*
Here is the whole load down, please let me know what I am doing wrong
