Re: [Gems-users] Stall time

[Dan Gibson <degibson@xxxxxxxx>]

Often, a memory stall time is not known at request-time. In this case, Ruby stalls Simics for a long long long time, but un-stalls it when Ruby determines its coherence actions have been completed.

Hi,

I'm studying ruby's core and  I'm curious about how a memory transaction can be returned with stall time like this:

 

   { Miss           , SIMICS_STALL_TIME},

 

which is to say an infinite stall time.

I don't know in what condition this is supposed to happen.

 

Thanks
