Re: [Gems-users] addresses for L1 and L2 caches, virtual or physical?

[Dan Gibson <degibson@xxxxxxxx>]

All addresses in Ruby are physical addresses. In some cases, the virtual address is available for profiling, but it is not used by the caches themselves.

Hi, all

  Currently, I am trying to simulate a two-level cache system, which each core has its private L1 cache and L2 cache is shared by all the cores.  I have a question about the addresses used by the L1 and L2 cache. What type of addresses used by them? Both of them use Physical address or L1 uses virtual address and L2 uses Physical address? 

  Thanks a lot for your help.
