| 2014-02-24 | ruby: correct errors in changeset 4eec7bdde5b0 | Nilay Vaish | |
| Couple of errors were discovered in 4eec7bdde5b0 which necessitated this patch. Firstly, we create interrupt controllers in the se mode, but no piobus was being created. RubyPort, which earlier used to ignore range changes now forwards those to the piobus. The lack of piobus resulted in segmentation fault. This patch creates a piobus even in se mode. It is not created only when some tester is running. Secondly, I had missed out on modifying port connections for other coherence protocols. | |||
| 2014-01-04 | ruby: add a three level MESI protocol. | Nilay Vaish | |
| The first two levels (L0, L1) are private to the core, the third level (L2)is possibly shared. The protocol supports clustered designs. For example, one can have two sets of two cores. Each core has an L0 and L1 cache. There are two L2 controllers where each set accesses only one of the L2 controllers. | |||
