2007-03-233 memory system fixes:Kevin Lim
1. Update packet's flags properly when a snoop happens 2. Don't allow accesses to read a block's data if the block has outstanding MSHRs. This avoids a RAW hazard in MP systems that the memory system was not detecting properly earlier (a write required a block to upgrade, and while the upgrade was outstanding, a read came along and read old data). 3. Update MSHR's request upon a response being handled. If the MSHR has more targets than it can respond to in one cycle, then its request must be properly updated to the new head of the targets list. src/mem/bus.cc: Update packet's flags properly upon snoop. src/mem/cache/cache_impl.hh: Be sure to not allow accesses to a block with outstanding MSHRs. src/mem/cache/miss/miss_queue.cc: Update MSHR's request upon a response being handled. --HG-- extra : convert_revision : 76a9abc610ca3f1904f075ad21637148a41982d6
