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
2007-03-10Rework the way SCons recurses into subdirectories, making itNathan Binkert
automatic. The point is that now a subdirectory can be added to the build process just by creating a SConscript file in it. The process has two passes. On the first pass, all subdirs of the root of the tree are searched for SConsopts files. These files contain any command line options that ought to be added for a particular subdirectory. On the second pass, all subdirs of the src directory are searched for SConscript files. These files describe how to build any given subdirectory. I have added a Source() function. Any file (relative to the directory in which the SConscript resides) passed to that function is added to the build. Clean up everything to take advantage of Source(). function is added to the list of files to be built. --HG-- extra : convert_revision : 103f6b490d2eb224436688c89cdc015211c4fd30

directly configured by python. Move stuff from root.(cc|hh) to core.(cc|hh) since it really belogs there now. In the process, simplify how ticks are used in the python code. --HG-- extra : convert_revision : cf82ee1ea20f9343924f30bacc2a38d4edee8df3
