2018-03-23learning_gem5: Add a simple config for MI_exampleJason Lowe-Power
Adds a new config script to configure the MI_example protocol. This script closely follows the script used for MSI, but instead supports the MI_example protocol. This script works with the simple_ruby runscript and can be included instead of msi_caches.

2018-03-23learning_gem5: Add config files for MSI protocolJason Lowe-Power
Adds the required configuration files to run the MSI protocol. These config files are much simpler than the current Ruby examples and follow the pattern in the other Learning gem5 run scripts. By default, this script runs with two CPUs and runs the recently added thread test binary. Currently, only SE mode is supported.

2016-11-09syscall_emul: [patch 5/22] remove LiveProcess class and use Process insteadBrandon Potter
The EIOProcess class was removed recently and it was the only other class which derived from Process. Since every Process invocation is also a LiveProcess invocation, it makes sense to simplify the organization by combining the fields from LiveProcess into Process.
2017-02-14mem: Update DRAM configuration namesWendy Elsasser
Names of DRAM configurations were updated to reflect both the channel and device data width. Previous naming format was: <DEVICE_TYPE>_<DATA_RATE>_<CHANNEL_WIDTH> The following nomenclature is now used: <DEVICE_TYPE>_<DATA_RATE>_<n>x<w> where n = The number of devices per rank on the channel x = Device width Total channel width can be calculated by n*w Example: A 64-bit DDR4, 2400 channel consisting of 4-bit devices: n = 16 w = 4 The resulting configuration name is: DDR4_2400_16x4 Updated scripts to match new naming convention. Added unique configurations for DDR4 for: 1) 16x4 2) 8x8 3) 4x16 Change-Id: Ibd7f763b7248835c624309143cb9fc29d56a69d1 Reviewed-by: Radhika Jagtap <radhika.jagtap@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com>
2016-11-30mem: Split the hit_latency into tag_latency and data_latencySophiane Senni
If the cache access mode is parallel, i.e. "sequential_access" parameter is set to "False", tags and data are accessed in parallel. Therefore, the hit_latency is the maximum latency between tag_latency and data_latency. On the other hand, if the cache access mode is sequential, i.e. "sequential_access" parameter is set to "True", tags and data are accessed sequentially. Therefore, the hit_latency is the sum of tag_latency plus data_latency. Signed-off-by: Jason Lowe-Power <jason@lowepower.com>
2016-10-14config: Make configs/common a Python packageAndreas Hansson
Continue along the same line as the recent patch that made the Ruby-related config scripts Python packages and make also the configs/common directory a package. All affected config scripts are updated (hopefully). Note that this change makes it apparent that the current organisation and naming of the config directory and its subdirectories is rather chaotic. We mix scripts that are directly invoked with scripts that merely contain convenience functions. While it is not addressed in this patch we should follow up with a re-organisation of the config structure, and renaming of some of the packages.
2015-10-01config: Fix 'learning gem5' configs after SMT pushAndreas Hansson
This patch updates the 'learning gem5' example scripts to match the recent push of the SMT patches.
2015-09-16config: Add configs scripts used in Learning gem5Jason Lowe-Power
Added a new directory in configs (learning_gem5) to hold the scripts that are used in the book. See http://lowepower.com/jason/learning_gem5/ for a working copy. For now, only the scripts in Part 1: Getting started with gem5 have been added. A separate patch adds tests for these scripts. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
