From f5b52a265afe9d4bd0144b0e2d7a0d9fcdbcbd3f Mon Sep 17 00:00:00 2001 From: Nilay Vaish Date: Fri, 20 Dec 2013 20:34:03 -0600 Subject: ruby: mesi: remove owner and sharer fields from directory tags The directory controller should not have the sharer field since there is only one level 2 cache. Anyway the field was not in use. The owner field was being used to track the l2 cache version (in case of distributed l2) that has the cache block under consideration. The information is not required since the version of the level 2 cache can be obtained from a subset of the address bits. --- configs/ruby/MESI_CMP_directory.py | 1 + 1 file changed, 1 insertion(+) (limited to 'configs/ruby') diff --git a/configs/ruby/MESI_CMP_directory.py b/configs/ruby/MESI_CMP_directory.py index 2dba25b1a..95b4904a5 100644 --- a/configs/ruby/MESI_CMP_directory.py +++ b/configs/ruby/MESI_CMP_directory.py @@ -174,6 +174,7 @@ def create_system(options, system, piobus, dma_ports, ruby_system): use_map = options.use_map), memBuffer = mem_cntrl, + l2_select_num_bits = l2_bits, transitions_per_cycle = options.ports, ruby_system = ruby_system) -- cgit v1.2.3
