2018-08-17util: add util/maint/show_changes_by_file.py toolBrandon Potter
The script diffs an upstream branch and a feature branch to find all files which have been changed between the branches. It then searches for all the corresponding changesets and binds them to the files in the output. The tool's output resembles the following: /path/to/file/ filename git-hash git-hash filename git-hash /path/to/file/ filename git-hash Change-Id: Icd67953748f38dad984488c5445313eaa56fa202 Reviewed-on: https://gem5-review.googlesource.com/7861 Reviewed-by: Brandon Potter <Brandon.Potter@amd.com> Maintainer: Brandon Potter <Brandon.Potter@amd.com>

2018-06-15tests,style: add RISC-V assembly testsTuan Ta
This patch adds a subset (rv64*) of RISC-V assembly tests. The original riscv-test project can be found here: https://github.com/riscv/riscv-tests. The riscv-test project is under the BSD license (https://github.com/riscv/riscv-tests/blob/master/LICENSE) and is maintained separately from gem5 project. The tests have been slightly modified to work in gem5 SE mode: (1) Removed a trap handler used in riscv-tests for bare-metal systems (2) Instead of throwing an exception, the tests call the exit syscall with the exit code of - '0' if SUCCESS - Failed test case's number (non-zero) if FAILURE The exit code can be captured after a simuation completes. In addition to original RISC-V assembly tests, this patch adds several assembly tests specifically for AMO, LR, SC and system calls. Those tests target a multi-core system. (1) rv64uamt: multi-threaded tests for A-extension instructions (2) rv64samt: multi-threaded tests for clone and futex system calls This patch also makes the style checker ignore RISC-V assembly test directory. The assembly tests are maintained in an external project that does not follow the gem5 coding conventions. Please find more details in the README file included in this patch.

This change adds a script to generate graphs from the stats file output by the configuration script low_power_sweep.py. The graphs show stacked bars for time spent and energy consumed wherein each component of the stacked bar represents a DRAM power state (Idle, Refresh, Active, Active Power-down, Precharge Power-down and Self-refresh). The script generates one plot per delay value. It also generates a pdf (--pdf option) in which the graphs are laid out such that you can easily compare how the increasing delay and other swept params affect the resulting energy.

2017-11-14util: Optionally search entire history when listing changesAndreas Sandberg
The helper script to list changes currently only looks at the changes between a branch point and two heads. This helps performance, but sometimes misclassifies changes that exist both in the upstream branch before the branch point and in a feature branch. Such changes should normally not exist, but can be the product of an incorrect rebase. This change adds an option to the helper script to search the entire upstream repo history when determining the set of upstream changes. When this option is provided, the script lists the changes that exist upstream before the branch point and in the feature branch as "Incorrectly rebased changes".

The aforementioned registers (Interrupt Processor Targets Registers) are banked per-CPU, but are read-only. This patch eliminates the per-CPU storage of these values that are simply computed.

2017-02-14sim: allow forward dependencies in checkpoint upgradersCurtis Dunham
The notion of forward dependencies is just expressing the same dependency but at the other end of the dependency edge, i.e. at the dependee rather than the depender. As there is no more 'power' here, it's strictly a convenience feature for handling dependencies with tags that are not in the upstream repository.

2017-02-14sim: add support for checkpoint downgradingCurtis Dunham
This commit supports the use case of transitioning tags and their associated checkpoint rewrites out of use for whatever reason. Just replace the upgrader() method with a downgrader() method that performs the appropriate inverse operation. The tag name is still used, but only in this negative, 'zombie' state, as it will be removed from the tags in the checkpoint and gem5 binary.
