[Gems-users] what does the 'may_stall' bit mean in memory transcation?

["huangyongbing" <huangyongbing@xxxxxxxxxx>]

When I try to dump all the memory requests coming from the simics in SimicProcessor, I find that there are so many continous requests which access continous physical addresses and their may_stall attributes are sent to '0'. However, the running benchmark doesn't access continous addresses. In the following procedure, requests with cleared may_stall attribute are returned immediately and not sent to cache. 

 

Thus, what does the 'may_stall' attribute mean in memory transcations?

 

Thanks for advance.
