Hi,
Thank you for your response with the patch link. It helped me a lot to understand what's going on
and limitations with clflush.
Do you have any idea if clflush alternative for arm isa is implemented in gem5 properly or not. I
work on persistent memory and for x86 isa, you need clflush and fence ( which also may not be
implemented properly). If I move to arm, clflush and fence should be replaced with
similar functionality instruction ( I have no idea about arm isa, sorry can't mention explicit
instruction. Most likely DC CVAU and memory barrier in arm isa ).
These will boil down to the same micro-ops, just so you know ...
