* Support for less than 8 threads per coreDan Crowell2013-02-081-1/+2
| | | | | | | | | | | Modified anywhere that we enable non-master threads to only touch the threads that we are told to update.

* Support RPR register.Patrick Williams2013-01-141-1/+14
| | | | | | | | | | | | | | | | | | | | For P8 the priority of different threads has no effect unless the relative priority register is programmed to tell the relative scheduling weight of the different priorities. We will now be programming the RPR to give 32x performance boost to "high" priority threads relative to "low" priority. This means that when a thread is waiting on another, and thus has low priority, it will get 32x less dispatch cycles then the thread it is waiting on.

* Allow processors on logical nodes != 0.Patrick Williams2012-09-061-29/+55
| | | | | | | | | | | | | | | | | Created per-node arrays of CPU objects rather than a single array for the entire system. These are created dynamically as CPUs are enabled. Also disabled support for P7 due to the PIR layout being different and hence would have needed two different sets of assembly code. We have been running exclusively on the P8 Mambo model for a while.

| | | | | | | | | | | | | | | | | | | | | | Updating the Simics level to get FSI fixes to allow multiple chips to work. This also allows us to remove some previous workarounds. The new Simics build pulled in a different PNOR so needed to disable some of the tests. The new Simics build also modified some of the L3 objects so changes were required to some debug tools.
