Added full-system support to the simple mesh toplogy by allowing dma contrllers
to be attached to router zero in the network.
|

|
|
Make sure that instructions are dereferenced/deleted twice by marking they are
on the remove list

- 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
|
|
only show requests processed when the resource is actually in use
|
|
- m5 line enforcement on use_def.cc,hh
|
|
add idle/run/utilization stats for each pipeline stage
|
|
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
|
|
set Active/Suspended/Halted status for threads. useful for system when determining
if/when to exit simulation
|
|
Halt is called from the exit() system call while
deallocate is unused. So to clear up things, just
use halt and remove deallocate.
|
|
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
|
|
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
|
|
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.
|
|
this prints out messages relative to what
threading model is being used (smt, switch-on-miss, single, etc.)
|
|
update address List and address Map to take
into account multiple threads
|
|
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...
|
|
dont check total # of threads but instead all
active threads
|
|
update/add in the use of isThreadReady & isThreadSuspended
functions.Check in activateThread what list a thread is
on so it can be managed accordingly.
|
|
|
|
-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
|
|
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
|
|
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
|
|
some events are going to need instruction data when they process, so just
include the instruction in the event construction
|
|
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
|
|
- 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)
|
|
|
|
- cpuEventNum
- resReqCount

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.
--HG--
rename : tests/quick/50.memtest/test.py => tests/quick/60.rubytest/test.py
|
|
Replaced Ruby debug statements with M5 statements.
|
|
Removed the last level cache support and MOESI_hammer's dependency on it.
Replaces the LLC support with the more generic MachineType count.
|
|
|
|
Removed static members in RubyPort and removed the ruby request unique id.
|
|
Removed the old config interface from RubySystem and libruby.
|
|
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.

Rename the ruby/network/garnet-foo directories to garnet/foo.
Move the common NetworkHeader.hh file from garnet-fixed-pipeline
up to the common garnet directory.
Fix up include paths.

Renamed the MESI directory file to be consistent with all other protocols.

I'm not sure how this got past our initial ruby code import, but this obviously
needed to be removed.
