The allocation decision is thus based both on the cacheability of the line, and the snooping status of the source port. Ultimately we should check if the source of the packet is caching, since also the CPU ports are snooping (but not allocating). Thus, at the moment we rely on the snoop filter being used together with caches. The patch also transitions to use the Packet::getBlockAddr in determining the line address. |
