I had posted a review request, it is not appropriate to respond to it with
these type of questions. These questions should be asked on gem5-users
list.
And now the answer to your question. We currently do not update GEMS code.
And I do not think that there is any plan to do so in future. In fact, we
advise users to move to gem5.

Hi.
I am currently using GEMS and Simics. So I care about whether the corresponding
codes are also updated in GEMS.

Ruby: Add support for functional accesses
This patch is meant for implementing functional access support in Ruby.
There is one significant change from the previous version of the patch.
In the previous version, during functional writes, only the cache memories
were being checked. During testing I realized that some of the cache lines
could reside in the TBEs. So, now the check is being done at the controller
level. The controller has to provide a function called getAccessPermission()
for functional accesses to be successful. The default implementation of the
function returns busy which means that the functional access cannot
proceed further.
The patch has been tested only for 1 loads and processor count from 1
to 16.

Testing
---
I have tested functional accesses with the ratio between functional
and timing accesses for different ratios -- 100:0, 99:1, 90:1, 50:50,
10:90, 1:99. It is working in all the cases.
Thanks,
Nilay
