From 3022d463fbe1f969aadf7284ade996539c9454f9 Mon Sep 17 00:00:00 2001 From: Nilay Vaish Date: Thu, 6 Nov 2014 05:42:21 -0600 Subject: ruby: interface with classic memory controller This patch is the final in the series. The whole series and this patch in particular were written with the aim of interfacing ruby's directory controller with the memory controller in the classic memory system. This is being done since ruby's memory controller has not being kept up to date with the changes going on in DRAMs. Classic's memory controller is more up to date and supports multiple different types of DRAM. This also brings classic and ruby ever more close. The patch also changes ruby's memory controller to expose the same interface. --- configs/example/ruby_direct_test.py | 20 ++++++-------------- 1 file changed, 6 insertions(+), 14 deletions(-) (limited to 'configs/example/ruby_direct_test.py') diff --git a/configs/example/ruby_direct_test.py b/configs/example/ruby_direct_test.py index 6773aea6d..857909ba9 100644 --- a/configs/example/ruby_direct_test.py +++ b/configs/example/ruby_direct_test.py @@ -48,7 +48,7 @@ m5_root = os.path.dirname(config_root) parser = optparse.OptionParser() Options.addCommonOptions(parser) -parser.add_option("-l", "--requests", metavar="N", default=100, +parser.add_option("--requests", metavar="N", default=100, help="Stop after N requests") parser.add_option("-f", "--wakeup_freq", metavar="N", default=10, help="Wakeup every N cycles") @@ -87,13 +87,8 @@ else: print "Error: unknown direct test generator" sys.exit(1) -# -# Create the M5 system.
