H A D | inst.proto | diff 12602:69eb7c6e5f7f Thu Jan 25 03:03:00 EST 2018 Gabe Black <gabeblack@google.com> cpu: Make the protobuf inst tracer accept variable sized instructions. This change adds an inst_bytes field which is of type bytes, and puts it in a oneof with the previously required inst field. If an instruction's encoding happens to be 4 bytes long, the original inst field will be used. Otherwise, the new variably sized inst_bytes field will be used. Because this tracer doesn't have visibility into how the data in inst_bytes is structured, it can't do any endian conversion itself. To maintain compatibility between producers and consumers who may have different endiannesses, all data should be manually converted to little endian before being stored in this field. inst will be converted into little endian by protobuf, and so compatibility doesn't have to be handled manually.

H A D | MOESI_hammer.py | diff 7561:02a9a597fce4 Fri Aug 20 14:46:00 EDT 2010 Brad Beckmann <Brad.Beckmann@amd.com> ruby: Disable migratory sharing for token and hammer This patch allows one to disable migratory sharing for those cache blocks that are accessed by atomic requests. While the implementations are different between the token and hammer protocols, the motivation is the same. For Alpha, LLSC semantics expect that normal loads do not unlock cache blocks that have been locked by LL accesses. Therefore, locked blocks should not transfer write permissions when responding to these load requests. Instead, only they only transfer read permissions so that the subsequent SC access can possibly succeed. |
