82c5a754e6 inorder: recvRetry bug fix 
- on certain retry requests you can get an assertion failure
- fix by allowing the request to literally "Retry" itself
  if it wasnt successful before, and then block any requests
  through cache port while waiting for the cache to be
  made available for access

Korey Sewell
4d749472e3 inorder: enforce stage bandwidth 
each stage keeps track of insts_processed on a per_thread basis but we should
be keeping that on a total basis inorder to enforce stage width limits

b4e0ef7837 inorder: set thread status' 
set Active/Suspended/Halted status for threads.  useful for system when determining
if/when to exit simulation
 2010-01-31 18:28:12 -05:00
Korey Sewell
5e0b8337ed inorder: add/remove halt/deallocate context respectively 
Halt is called from the exit() system call while
deallocate is unused. So to clear up things, just
use halt and remove deallocate.
 2010-01-31 18:28:05 -05:00
Korey Sewell
069b38c0d5 inorder: track last branch committed 
when threads are switching in/out the CPU, we need to keep
track of special cases like branches. Add appropriate
variables in ThreadState t track this and then use
these variables when updating pc after context switch
 2010-01-31 18:27:58 -05:00
Korey Sewell
aacc5cb205 inorder: add updatePC event to resPool 
this will be used for when a thread comes back from a cache miss, it needs to update the PCs
because the inst might of been a branch or delayslot in which the next PC isnt always
a straight addition
 2010-01-31 18:27:49 -05:00
Korey Sewell
90d3b45a56 inorder: ready thread wakeup 
allow a thread to wakeup and be activated after
it has been in suspended state and another
thread is switched out. Need to give
pipeline stages a "activateThread" function
so that can get to their suspended instruction
when the time is right.
 2010-01-31 18:27:38 -05:00
Korey Sewell
3eb04b4ad7 inorder: add threadmodel flag 
this prints out messages relative to what
threading model is being used (smt, switch-on-miss, single, etc.)

611a8642c2 inorder: mem. mgmt. update 
update address List and address Map to take
into account multiple threads
 2010-01-31 18:27:12 -05:00
Korey Sewell
4dbc2f1718 inorder: suspend in respool 
give resources their own specific
activity to do for a "suspend" event
instead of defaulting to deactivating the thread for a
suspend thread event. This really matters
for the fetch sequence unit which wants to remove the
thread from fetching while other units want to
ignore a thread suspension. If you deactivate a thread
in a resource then you may lose some of the allotted
bandwidth that the thread is taking up...

4ea296e296 inorder: fetch thread bug 
dont check total # of threads but instead all
active threads
 2010-01-31 18:26:54 -05:00
Korey Sewell
96b493d315 inorder: ready/suspend status fns 
update/add in the use of isThreadReady & isThreadSuspended
functions.Check in activateThread what list a thread is
on so it can be managed accordingly.

Korey Sewell
e1fcc64980 inorder: activate thread on cache miss 
-Support ability to activate next ready thread after a cache miss
through the activateNextReadyContext/Thread() functions
-To support this a "readyList" of thread ids is added
-After a cache miss, thread will suspend and then call
activitynextreadythread
 2010-01-31 18:26:32 -05:00
Korey Sewell
4a945aab19 inorder: add event priority offset 
allow for events to schedule themselves later if desired. this is important
because of cases like where you need to activate a thread only after the previous
thread has been deactivated. The ordering there has to be enforced

Korey Sewell
eac5eac67a inorder: squash on memory stall 
add code to recognize memory stalls in resources and the pipeline as well
as squash a thread if there is a stall and we are in the switch on cache miss
model
 2010-01-31 18:26:13 -05:00
Korey Sewell
d8e0935af2 inorder: add insts to cpu event 
some events are going to need instruction data when they process, so just
include the instruction in the event construction
 2010-01-31 18:26:03 -05:00
Korey Sewell
e8312ab6f7 inorder: switch out buffer 
add buffer for instructions to switch out to in a pipeline stage
can't squash the instruction and remove the pipeline so we kind of need
to 'suspend' an instruction at the stage while the memory stall resolves
for the switch on cache miss model
 2010-01-31 18:25:48 -05:00
Korey Sewell
a892af7b26 inorder: dont allow early loads 
- loads were happening on same cycle as the address was generated which is slightly
unrealistic. Instead, force address generation to be on separate cycle from load
initiation
- also, mark the stages in a more traditional way (F-D-X-M-W)

ab2f864af2 m5: Regression Tester Update 
This patch includes the necessary regression updates to test the new ruby
configuration system.  The patch includes support for multiple ruby protocols
and adds the ruby random tester.  The patch removes atomic mode test for
ruby since ruby does not support atomic mode acceses.  These tests can be
added back in when ruby supports atomic mode for real.

e4218dd08f ruby: Re-enabled orion power models 
Removed the dummy power function implementations so that Orion can implement
them correctly.  Since Orion lacks modular design, this patch simply enables
scons to compile it.  There are no python configuration changes in this patch.
