[Gems-users] Question about how OPAL handles DTLB miss

["shanshuchang" <shanshuchang@xxxxxxxxx>]

Hi all,

I am studying the OPAL codes and I am puzzled how the OPAL handles a Data TLB miss.

For example, when a LD inst is scheduled to be executed, it need to do address generation with the help of function mmuAccess (in memop.C file).
In such a situation, when a exception occurs, the Execute() function just return.
So I wonder, how does the OPAL module handle the DTLB miss exception?

 

Thanks in advance!
