Thank you, I think I figured out how to do.
If I want to print sth in arch-relevant code like cache_impl.hh,
1. I need to define my own Flag, Let's say the flag is myflag1
2. Add printf like this : DPRINTF(myflag1, “The world is so small %s\n”,
“arguments”); in the arch-relevant code
3. Add declaration of my flag in src/mem/cache/SConscript
like this:
DebugFlag('myflag1')
4. Add #include debug/myflag1.hh in the file you put DPRINTF to output
5. Rebuild
6. Add --debug-flag=myflag1 in the running command
OK now.
