This patch developed by Nilay Vaish converts all the old GEMS-style ruby
debug calls to the appropriate M5 debug calls.
|
|
Added an optimization that merges multiple pending GETS requests into a
single request to the owner node.
|
|
This patch allows messages to be stalled in their input buffers and wait
until a corresponding address changes state. In order to make this work,
all in_ports must be ranked in order of dependence and those in_ports that
may unblock an address, must wake up the stalled messages. Alot of this
complexity is handled in slicc and the specification files simply
annotate the in_ports.

Patch allows each individual message buffer to have different recycle latencies
and allows the overall recycle latency to be specified at the cmd line. The
patch also adds profiling info to make sure no one processor's requests are
recycled too much.

This patch tracks the number of cycles a transaction is delayed at different
points of the request-forward-response loop.

The previous slower ruby latencies created a mismatch between the faster M5
cpu models and the much slower ruby memory system. Specifically smp
interrupts were much slower and infrequent, as well as cpus moving in and out
of spin locks. The result was many cpus were idle for large periods of time.
These changes fix the latency mismatch.

Reordered vnet priorities to agree with PerfectSwitch for protocols MI_example,
MOESI_CMP_token, and MOESI_hammer
|
|
|
|
Removed the last level cache support and MOESI_hammer's dependency on it.
Replaces the LLC support with the more generic MachineType count.

This patch includes the necessary changes to connect ruby objects using
the python configuration system. Mainly it consists of removing
unnecessary ruby object pointers and connecting the necessary object
pointers using the generated param objects. This patch includes the
slicc changes necessary to connect generated ruby objects together using
the python configuraiton system.
|
|
Also add SLICC support for state-machine parameter defaults
(passed through to Python as SimObject Param defaults).
